Answer:

with what?

Step-by-step explanation:

Answer:

A= C + 12%C = 1.12C

S=.C -2%C = .98C

A,C and S are the speeds of Alex, Cameron and Sam

400 meter race

how far is Sam from the finish line when Alex crosses the finish line?

distance = speed times time

400 = AT where T=Alex' finish time

400=1.12T

400=CU where U = Cameron's finish time

400=SV where V = Sam's finish time

T<U<V

Alex' finish time is less than Cameron's finish time is less than Sam's finish time

if Cameron runs at 20 meters per second, finishing in 20 seconds

then Sam is about 50 meters from the finish line when Alex finishes

sorry if i´m too late, hope this helps!

Since y is directly proportional to x then the value of y is 8

In a proportional relationship, one variable is always equal to the constant value of the other.

It is clear that y increases in proportion to x by applying the direct proportionality formula, y = kx.

Given y is directly proportional to x.

Therefore y = kx

now at x = 20 , y = 16/5

∴16/5 = 20 k

or, k = 16 /100

Now at x = 50 ,

Y = 16 /100 × 50

or, y = 8

Therefore that value of y is 8.

Yes, it is a solution

y = -10x + - 4

The given point: (0, -4)

To know if it is a solution, we need to replace the y and x with the points given.

If the result on the left hand side is the same as the right hand side then, it is a solution

x =0, y = -4

-4 = -10(0) + -4

-4 = 0 + (-4)

Multiplication of same sign gives positive number. Multiplication of opposite signs give negative number.

-4 = 0 - 4

-4 = -4

The left hand side is the same as the right hand side. Hence, it is a solution

Answer:

Yes it is a solution

Step-by-step explanation:

y = -10x + - 4

Answer:

y = -x - 7

Step-by-step explanation:

Perpendicular to the slope m = 1 is the slope -1/m = -1.

y = m * (x - Px) + Py

y = -1 * (x - 2) + (-9)

y = -x + 2 - 9

y = -x - 7

The lottery's anticipated worth is $80.

Given that,

The probability of receiving $125 is 0.25; the likelihood of receiving $100 is 0.3; and the likelihood of receiving $50 is 0.45.

A) EV=125*.2+100*.3+50*.5=$80

The lottery's anticipated worth is $80.

The expected value is obtained by multiplying each result by its likelihood.

The expected value of the lottery is then calculated by adding up all of these.

This is what we have: ;;

125(0.2) + 100(0.3) + 50(0.5) (0.5)

= 25 + 30 + 25 = $80

B) This is the formula for variance is shown in figure :

So, we can calculate the variance as follows:

.2*(125-80)^2+.3*(100-80)^2+.5*(50-80)^2=975

C) A risk-neutral person would pay $80 or less to play the lottery.

Answer:

Step-by-step explanation:

Expected value of the lottery is $83.75.

Variance of the outcome is 909.6.

A risk-neutral person would pay $83.75 or less to play the lottery.

a) The expected value is obtained by multiplying each result by its likelihood.

This is,

125(0.25) + 100(0.3) + 50(0.45)

          = $83.75

b) we can calculate the variance as follows:

Variance=.25*(125-83.75)^2+.3*(100-83.75)^2+.45*(50-80)^2=909.6

The equation for the line that passes through the given point and is perpendicular to the given line is x - 4y = 3

Given : x - 4y = 8

4y = x- 8

On dividing by 4 we get;

y= x/4 - 2

This is of the form y = mx + c

Thus m in this case on comparing we get m= 1/4

We know the formula of the slope ;

y - y₁ =m ( x - x₁ )

y - 1 = 1/4 ( x- 7)

On cross multiplying we get ;

x- 4y = 3

Step-by-step explanation:

24/6=4

4x6=24

Answer:

110

Step-by-step explanation:

To find the measure of the exterior angle we first need to find the value of t.

The sum of interior angles in a triangle is equal to 180° so we can write the following equation:

t + 10 + t + t + 20 = 180 add like terms

3t + 30 = 180 subtract 30 from both sides

3t = 150 divide both sides by 3

t = 50

The exterior angles and the angle represented with t + 20 make a straight line

and they are supplementary angles so their sum is equal to 180

t + 20 = 70 to complete this to 180 we need 110

What is Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

100 times my number is 12.6 more than 5000

Let the number be x

100 times the number = 100x

Now, 100x is 12.6 more than 5000

100x = 5000 + 12.6

100x = 5012.6

Divide by 100 on both sides , we get

No, it is not feasible to produce any two structuring elements that is not always congruent with one another. This is because equilateral triangles have no internal angles.

This is further explained below.

Generally, In the field of geometry, a triangle is said to be equilateral if all three of its sides have the same length.

In the well-known geometry of Euclidean, an equilateral triangle is also an equiangular triangle. This means that all three of the triangle's interior angles are equivalent to each other and are each 60 degrees.

No, it is not possible to create any two equilateral triangles that are not always congruent with one another.

In conclusion, The logic for this is that while each angle in an equilateral triangle is 60 degrees, the sides of the triangle cannot always be identical.

The total surface area of the triangular prism is 756 meter²

Given,

A triangular prism and its net.

We have to find the surface area of the triangular prism.

First we can consider the right angled triangle.

Height = 9 meter

Base = 12 meter

Hypotenuse = 15 meter

Area of the right angled triangle = (1/2 bh)

Here,

Area = 2 × (1/2 bh) = 2 × (1/2 × 12 × 9) = 2 × 6 × 9 = 108 meter²

Now, area of right rectangle.

Area of rectangle = length × breadth

Here, the breadth of the rectangle is the height of the triangle = 9 meter

Length = 18 meter

Area = length × breadth = 9 × 18 = 162 meter²

Then, area of middle rectangle.

Length = 18 meter

Breadth = 12 meter

Area = length × breadth = 18 × 12 = 216 meter²

Next, area of left rectangle.

Length = 18 meter

Breadth = Hypotenuse of the triangle = 15 meter

Area = length × breadth = 18 × 15 = 270 meter²

Now, lets calculate the total surface area of the triangular prism.

Surface Area of triangular prism = 108 + 162 + 216 + 270 = 756 meter²

The dimensions of the mold are a length and width of 3 inches and a height of 7 inches.

The volume of a rectangular prism is the space that it contains. We know that the volume of any prism is calculated by multiplying its base area by its height.

Given :

Let's assume that the length and the width of the "box" is x.

It is said that the height is 4 inches greater, so the height is x+4.

The volume of the mold is:

V = (x)(x)(x +4)

V = x²(x +4 ) using the Distributive Property.

V = x³ + 4x²

Since from the question we have Volume = 63 cubic inches

The equation we have is,

63 = x³ + 4x²

Subtracting 63 from both sides of the equation,

x³ + 4x²- 63 = 0

The cubic equation can be written as,

(x−3)(x²+7x+21) = 0

The solution of the quadratic equation (x²+7x+21) is,

x = -b ±√(b² - 4ac) / 2a

a = 1 , b =7 and c = 21

Substituting the values in the formula,

x = -7 ±√(7² - 4(1(21)) / 2(1)

x = -7 ±√-35 / 2

Hence,there are no real solutions to the quadratic equation.

There is only one real solution to the equation x = 3.

Therefore, the length and width of the rectangular prism are 3 inches and the height is x+4 = 3+4 = 7 inches.
