The diagonal of a square is x units. What is the area of the square in terms of x?

Answers

Answer 1

The area of the square is (x²/2) square units.

We are given a square. The length of the diagonal of the square is x units. We have to find the area of the square in terms of "x".

Let the side of the square be denoted by the variable "s". We will use the Pythagorean theorem to find the length of the side of the square.

s² + s² = x²

2s² = x²

s² = x²/2

s = √(x²/2)

s = (x/√2)

The area of the square is given by the square of the side length. Let the area of the square be denoted by the variable "A".

A = s²

A = (x/√2)²

A = x²/2

Hence, the area of the square is (x²/2) square units.

Answers

Trip of 700 km required 70 liter  gasoline

For go 200 km Distance total gasoline required = 20 liter

For go 1 km Distance total gasoline required = 20÷200

                                                                          =  0.1 liter

Total trip distance =700 km

Total gasoline required for  going 700 km = Total distance×Gasoline required for 1 km

 Total gasoline required for  going 700 km  = 700×0.01

70 liters of gasoline will be used on a trip of 700 kilometers.

Given that,

200 kilometer is covered by 20 liters of gasoline.

For go 1 km Distance total gasoline required = 20÷200

                                                                          =  0.1 liter

Now,

Let x be the liters of gasoline required for a 700-km trip.

            ⇒ 20/200 = x/700

            ⇒ (200) (x) = (20) (700)

            ⇒ 200x = 14,000

            ⇒ 200x/200 = 14,000/200

x-2/5=2/3-3x-2/6

Answers

Answer:

11/48

Step-by-step explanation:

x-2/5=2/3-3x-2/6

collect like terms

x-2/5 + 3x = 2/3 - 2/6

taking LCM on both sides

[(x-2) + 5(3x)]/5 = [2(2) -2]/6

(16x - 2)/5 = 2/6

cross multiply

6(16x - 2) = 5(2)

96x - 12 = 10

96x = 22

therefore; X = 22/96

= 11/48

CHECK:

(11/48 - 2)/5 = 2/3 - 3(11/48) - 2/6

[tex]x=\frac{11}{60}[/tex]

Step-by-step explanation:

Given the equation

[tex]x-\frac{2}{5}=\frac{2}{3}-3x-\frac{2}{6}[/tex]

Lets solve for x.

Simplify the right side of the equation.

Cancel the common factor of 2 and 6 .

Factor 2 out of 2 .

[tex]x-\frac{2}{5}=\frac{2}{3}-3x-\frac{2(1)}{2(3)}[/tex]

[tex]x-\frac{2}{5}=\frac{2}{3}-3x-\frac{1}{3}[/tex]

Combine the numerators over the common denominator.

[tex]x-\frac{2}{5}=-3x-\frac{2-1}{3}[/tex]

[tex]x-\frac{2}{5}=-3x-\frac{1}{3}[/tex]

Move all terms containing x to the left side of the equation.

Add [tex]3x[/tex] to both sides of the equation.

[tex]x-\frac{2}{5}+3x=\frac{1}{3}[/tex]

Add [tex]x[/tex] and [tex]3x[/tex].

[tex]4x-\frac{2}{5}=\frac{1}{3}[/tex]

Move all terms not containing x to the right side of the equation.

Add [tex]\frac{2}{5}[/tex] to both sides of the equation.

[tex]4x=\frac{1}{3}+\frac{2}{5}[/tex]

To write [tex]\frac{1}{3}[/tex] as a fraction with a common denominator, multiply by [tex]\frac{5}{5}[/tex] .

[tex]4x=\frac{1}{3}*\frac{5}{5} +\frac{2}{5}[/tex]

To write [tex]\frac{2}{5}[/tex] as a fraction with a common denominator, multiply by [tex]\frac{3}{3}[/tex]

[tex]4x=\frac{1}{3}*\frac{5}{5} +\frac{2}{5}*\frac{3}{3}[/tex]

Simplify.

Write each expression with a common denominator of 15 , by multiplying each by an appropriate factor of 1 .

A telecommunications company will be laying new fiber optic cables underground. One cable will be perpendicular to the road shown, passing through the point ( 7, 2 . At what point will the cable pass through the road?

Answers

The point at which this cable would pass through the road shown is at the y-intercept of (0, -17/2).

How to determine an equation and the point on this perpendicular line?

Mathematically, the slope of a straight line can be calculated by using this formula;

Slope, m = (Change in y-axis, Δy)/(Change in x-axis, Δx)

Slope, m = (y₂ - y₁)/(x₂ - x₁)

By critically observing the road shown in the graph above, the points on the line include the following:

Points (x, y) = (0, -2)

Points (x, y) = (-3, 0)

Substituting the given points into the formula, we have;

Slope, m = (0 + 2)/(-3 - 0)

Slope, m = 2/-3

Slope, m = -2/3.

In Mathematics, a condition that must be met for two lines to be perpendicular is given by:

m₁ × m₂ = -1

-2/3 × m₂ = -1

-2m₂ = -3

m₂ = 3/2

At point (7, 2), a linear equation for the line can be calculated by using the point-slope form:

y - y₁ = m(x - x₁)

Where:

m represents the slope.x and y represent the points.c represents the y-intercept.

Substituting the given points into the formula, we have;

y - 2 = 3/2(x - 7)

y - 2 = 3x/2 - 21/2

y = 3x/2 - 21/2 + 2

y = 3x/2 - 17/2

At the y-intercept of (0, -17/2), the cable pass through the road.

If you are tossing a six-sided die, what is the probability of getting either a 1 or a 2 on your first toss and a 1 or a 2 on your second toss?.

Answers

A six sided dice is tossed twice. The probability of getting either a 1 or a 2 on your first toss and a 1 or a 2 on your second toss is 1/9 .

A dice has six faces or sides and it is throws twice . When a dice is toss first time,

Total possible outcomes on toss = 6 ={ 1,2,3,4,5,6}

In our first toss we want to get 1 or 2

So, favourable outcomes of getting 1 or 2 = 2

Probability of getting 1 or 2 on first toss= favourable cases /total outcomes = 2/6 = 1/3

For second toss, we want to get a1 or a2 again.

Total possible outcomes = 6

Probability of getting a1 or a2 on second toss= 2/6= 1/3

Now, Multiply these probsbilites togethers and chance of getting 1 or 2 on first and second which is 1/3× 1/3 = 1/9

Hence , probability of getting either a 1 or a 2 on your first toss and a 1 or a 2 on your second toss is 1/9.

it takes an airplane 1 hour 30 minutes to fly 600 km against the wind. the return trip with the wind takes only 1 hour. find the total flying time for the round trip if there was no wind.

Answers

The total flying time for the round trip if there was no wind would be 2 hours 24 minutes. The result is obtained by using the elimination method.

What is elimination method?

The elimination method is a method for solving system of linear equations where we eliminate one variable so that we can get an equation in one variable. In doing that, we can either add or subtract the equations.

Given the case that an airplane takes 1 hour 30 minutes to fly 600 km against the wind. It takes only 1 hour in the return trip.

What would be the total flying time for the round trip if there was no wind?

Let's say:

v = the speed of the airplanew = the speed of the wind

When the airplane leaves,

v - w = 600 km / 1.5 hour

v - w = 400 kph ... (equation 1)

When the airplane returns,

v + w = 600 km / 1 hour

v + w = 600 kph ... (equation 2)

We eliminate the equation 2 and 1 to get the speed of the airplane.

v - w = 400 kph

v + w = 600 kph +

2v = 1000 kph

v = 1000 ÷ 2

v = 500 kph

For the round trip, the airplane would fly 600 × 2 = 1200 km.

The total flying time if there was no wind would be

t = s/v

t = 1200/500

t = 2.4 hour

t = 2 hours 24 minutes

Hence, the  total flying time for the round trip if there was no wind is 2 hours 24 minutes.

Solving the inequality -6.6 < 1.7 + u for u, the solution is simplified as: u > -8.3 or -8.3 < u.

What is an Inequality?

In maths, an inequality is defined as a statement that is used to compare two quantities that are unequal. For example, we can state that 5 is greater than 3 + 1, or 5x is less than 4x + 3x. We can equally state that a given value of a variable can be equal to or greater than a number, and so on.

Basically, we are comparing two unequal quantities when we state inequalities.

Given the inequality, -6.6 < 1.7 + u, we are asked to solve the inequality for u. That is, we need to find the possible value that u represents in the inequality or that would make the inequality true.

Therefore:

-6.6 < 1.7 + u

Subtract 1.7 from both sides

-6.6 - 1.7 < 1.7 + u - 1.7 [subtraction property of equality]

-8.3 < u

A graph can be vertically translated by moving the base graph up or down in the y-axis direction. Each point on a graph is moved k units vertically to translate the graph by that many units.

The rules for transforming a function f(x) into g(x):

g(x) = a·f(b(x-c)) + d

a = vertical dilation (stretch); reflects across x-axis if negativeb = horizontal dilation (stretch); reflects across y-axis if negativec = horizontal translation (shift); shift right if c is positive, left if c is negatived = vertical translation; up if d is positive, down if d is negative

In one day, the bakery made 719 bagels. The bagels were divided into 9 equal shipments. A few bagels
were left over and given to the baker. How many bagels did the baker get?

Answers

in order to solve this problem, we need to figure out the number of equal bagels go into the 9 crates.
719 bagels / 9 crates = 79 bagels per crate.
now that we know that there are 79 bagels per crate, we can multiply by the number of crates to see how many bagels were shipped out in total
9 crates * 79 bagels per crate = 711 bagels
now, we subtract how many bagels were made by how many were shipped to see how many are left.
719-711 = 8 bagels. this value makes sense because there is not enough bagels left to add an equal amount to each crate.
hope this helps!

Answer:

8 bagels

Step-by-step explanation:

This is a remainder division problem. We need to divide 719 by 9 and find the remainder.

First off, 9 is bigger than 7, so we need to move to the next digit. How many times does 9 go into 71? 9 times 7 is 63! That's the closest smaller number we can get, so I will write a 7 in the long division problem above the 1. I will subtract 63 from 71 to get 8.

      7

9 | 719

   -63

       8

Now, the 9 can be brought down, making our 8 into an 89. How many times does 9 go into 89? 9 times 9 is 81! That's the closest we can get! I will write a 9 by the 7 above the 9 in 719, and write 81 below the 89. Subtracting these leaves us with a remainder of 8.

      79

9 | 719

  -63 ↓

      89

      -81

         8

This means that the bagels were sent in 9 equal shipments of 79 bagels each, and the baker was left with 8 bagels!

Each of the original statements is presupposed to be false in an inverted statement. "If it is not snowing" would be the polar opposite of "If it is snowing." "Then it is not chilly" would be the polar opposite of "then it is cold."

Contrapositive statements:

When you reverse the hypothesis and the conclusion in a statement and reject both of them, you have a contrapositive statement. When the hypothesis and the conclusion are switched in this example and both are negated, the outcome is: If it is not a triangle, then it is not a polygon.

So, the given sentences are:

(A) If it is after midnight, Anissa is sleeping: Converse statements(B) If Anissa is sleeping, it is not after midnight: Inverse statements(C) If Anissa is sleeping, it is after midnight: Converse statements(D) If it is not after midnight, Anissa is sleeping: Inverse statements(E) If it is not after midnight, Anissa is not sleeping: Contrapositive statements(F) If Anissa is not sleeping, it is not after midnight: Contrapositive statements


Therefore, the statements are characterized as converse, inverse, and contrapositive statements as follows:

A) If it is after midnight, Anissa is sleeping: Converse statements(B) If Anissa is sleeping, it is not after midnight: Inverse statements(C) If Anissa is sleeping, it is after midnight: Converse statements(D) If it is not after midnight, Anissa is sleeping: Inverse statements(E) If it is not after midnight, Anissa is not sleeping: Contrapositive statements(F) If Anissa is not sleeping, it is not after midnight: Contrapositive statements

The scale of a map is 1:20 000. What area does 8 cm² represent?

Answers

The 8 cm² area on a map  represent the actual area = 3200000000 cm² .

Scale factor of a map

S = 1/20000

The scale factor for area is found by squaring the scale factor for length. Thus the scale factor for area is S^2

When applied to the area we consider  S^2 as a scale factor.

The area on the map = 8 cm²

So The actual area = 8 × (20000)^2 = 8× 20000×20000

=3200000000 cm²  = 320000 m² =32 hectare.

So the 8 cm² area on a map  represent the actual area = 3200000000 cm² .

The graph of the function, f(x) = x2 - 5x - 7 opens
and has a
value.

Answers

The parabola has a positive leading coefficient, which means that it opens upwards.

The graph opens up or down?

We want to find the leading coefficient and see how the parabola opens.

A general quadratic equation is written as:

y = A*X^2 +b*X+ c

Where a is the leading coefficient.

If a is positive, then the parabola opens upwards, and if a is negative, the parabola opens downwards.

In this case, the equation is:

y = x^2 - 5x - 7

The leading coefficient is a = 1, it is positive, so the parabola opens upwards.

Math trigonometry non right angle help please
guys please

Answers

Answer:

  about 21.3 cm²

Step-by-step explanation:

Given a triangle with three sides 6 cm, 8 cm, and 12 cm, and smallest angle 26.4°, you want the area.

Area using sine formula

  A = 1/2ab·sin(C)

  A = 1/2(12 cm)(8 cm)·sin(26.4°) ≈ 21.34 . . . . square units

Area using Heron's formula

The semiperimeter is ...

  s = (6 +8 +12)/2 = 13

The area is ...

  A = √(s(s -a)(s -b)(s -c))

  A = √(13·(13 -12)(13 -8)(13 -6)) = √(13·1·5·7) = √455

  A ≈ 21.33 . . . . square centimeters

The area of the triangle is about 21.3 cm².

Additional comment

The problem with over specifying the dimensions of a geometry problem is that it is often difficult to make them consistent. Here, the area values agree to three significant figures. That is about all we can expect, given the angle precision is 3 significant figures.

Your answer depends on the set of dimensions you choose to use. It will be different yet if you use the Law of Sines to find angle A or B for the Sine Formula, especially if you round the angle value to tenths.

A student used the equation below to create a table.
y = 2.50x
The student used 15 as one of the values for the x. Which ordered pair could be taken from the table?
O a 17.50, 15)
Ob (15, 17.50)
Oc 37.50, 15)
Od (15,37.50)

Answers

The resulting ordered pair is (15, 37.50) when the value of x as 15.

Ordered pair

Ordered pair refers a set of numbers that tells us where to find a point on a coordinate grid. In the grid, the first number represents the value on the x-axis and the second number represents the value on the y-axis.

Given,

A student used the equation below to create a table.

y = 2.50x

The student used 15 as one of the values for the x.

Here we need to find the resulting ordered pair.

Through the given question we have identified that the given function is,

y = 2.50x.

Here x represents the number of students.

Now, we have to calculate the y value for 15 number of students,

So, here we have to apply the value x as 15, then we get,

y = 2.50 (15)

Now, we have to perform the multiplication on it,

y = 37.50

Therefore, the resulting ordered pair is (15, 37.50)
