SOLUTION

In a photograph, a skyscraper measures 5.8 in, tall

The scale of the photo to the actual skyscraper is 1 : 245

That is 1 : 245 = 1 / 245 = 5. 8 / x

Cross- multiply we have:

1 X x = 5 . 8 X 245

x = 1421 inches in feet = 118.4167 feet

Answer: 80

Step-by-step explanation:

You do 2 times= 8 and multiply 8 to the 5 white and black tiles which equals 40+40=80.

The total area for the parallelogram shaped tiles Felix needs to buy is 80cm² at the price of $40.

In calculating for the area of parallelogram, the base is multiplied by the height, as the same way for calculating the area of a rectangle.

Given that, the base of one parallelogram shaped tile is 4cm with height as 2cm.

Area of one parallelogram shaped tile = 4cm × 2cm

Area of one parallelogram shaped tile = 8cm²

Total area for the 5black and 5white tiles = 10 × 8cm²

Total area for the 5black and 5white tiles = 80cm²

Therefore, Felix needs to buy a total of 80cm² of 10 parallelogram shaped tiles.

The value of g(x) will be expressed as g(x) = (x + 5)

A function may be defined as an expression in which for one value of input variable x there is only one value of output variable y. The input variable is called as independent variable and output variable is called dependent variable. Composite functions are the functions which are written as combination of two functions. A function f(x) may be defined as composite function of another function g(x) when it can be written as either f(g(x)) or g(f(x)). We know that f(x) = x⁹ and the composite function H(x) = f(g(x)) = (x + 5)⁹. So, from this we can say that the function g(x) will be given as (x + 50 as we put (x + 5) as x in the function H(x).

Given the following question:

The principal wants to estimate the percentage of students in the school who play video games, which is a good number of students. Selecting 30 random students and asking them if they play video games can represent the entire school. Asking 30 random students keeps it from being biased for example option B, asking 30 students who take coding classes is biased because they are in one specific class, they do not represent the majority of the school unless the school is a coding school.

The answer is the first option because it is a random sample of people to represent a population of people. This keeps the results from being biased so asking 30 random students is the way to go.

Answer:

y = 3x + 3 :D

Step-by-step explanation:

Equation of line: y = mx + b :)

b: Y intercept

m: Slope

Now lets solve :)

Lets find M first :)

We need 2 points so lets use (0,3) and (1,6) :)

We fist need to subtract :)

6 - 3 = 3

1 - 0 = 1

Now we divide :)

3/1 = 3

Lets put that into our equation :)

y = 3x + b

Now lets find B :)

To find b, we need to see where the line intercepts the y axis! This will be at point (0,3)!

The y intercept will be 3 :)

The final equation will be y = 3x + 3 :)

a. Greg can eat 8 breakfasts from 1 box.

b. The cost of 1 breakfast from a regular-sized box is $34.32.

c. Greg will enjoy 4 breakfast more.

a. A regular-sized box contains 12 servings. If Greg eats 1 1/2 servings for breakfast every day, the number of breakfasts that Greg can eat from 1 box will be:

= 12 ÷ 1 1/2

= 12 ÷ 1.5

= 8

b. Since the regular-sized box of cereal costs $4.29. The cost of 1 breakfast from a regular-sized box of cereal cost Greg will be:

= 8 × $4.29

= $34.32

c. If Greg purchased the family-sized box of cereal that contains 18 servings, the number of breakfasts will be:

= 18 ÷ 1.5

= 12 breakfast

The difference will be:

= 12 - 8

= 4 breakfast more.

Define Radicals

The √ symbol that is used to denote square root or nth roots. Radical Expression - A radical expression is an expression containing a square root.

The given expression is,

2√6(√2 + 5)

First, open the brackets

2√6 * √2 + 5 * 2√6

we know, √6 = √3 * 2 = √3 * √2

so, 2√3 * √2  * √2 + 10√6

We didn't open the both √6 values it's because we want to remove  root from √2 so as we know √2 * √2 = 2

2√3 * 2 + 10 * √6

=> 4√3 + 10 * √6

Now, put the values of √3 = 1.732 and √6 = 2.449

=> 4 *  1.732 + 10 * 2.449

=> 6.928 + 24.49

The equation of the line that passes through the points ( -3,18 ) and ( 2,-7 ) is f(x) = -5x + 3.

The formula for equation of line is expressed as;

y = mx + b

Where m is slope and b is y-intercept.

Given the data in the question;

Point 1( -3,18 )

Point 2( 2, -7 )

First, we find the slope of the line.

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

m = ( -7 - 18 ) / ( 2 - (-3) )

m = ( -25 ) / ( 2 + 3 )

m = ( -25 ) / ( 5 )

m = -5

Next, next we find the y-intercept

y = mx + b

18 = (-5)(-3) + b

18 = 15 + b

b = 18 - 15

b = 3

Now that the values of slope m and y-intercept b is known, plug these into y = mx + b to determine the equation of the line.

y = mx + b

y = (-5)x + 3

y = -5x + 3

Therefore, the equation of the line is y = -5x + 3

When we have two chords intersecting inside a circle, the products of the lengths of the segments are equal to one another. This means that for the given circle, we have the following:

10 * 4 = 5 * x

We can solve for x by multiplying 10 by 4, which is 40, and then dividing by 5, to isolate x, which is 8.

Let

x -----> the number of milliliters of the 3.5% solution

y ----> the number of milliliters of the 6% solution

we have that

3.5%=3.5/100=0.035

6%=6/100=0.06

5%=5/100=0.05

so

0.035x+0.06y=0.05(500) -------> equation A

and

x+y=500 -----> x=500-y ------> equation B

solve the system of equations

substitute equation B in equation A

0.035(500-y)+0.06y=0.05(500)

solve for y

17.5-0.035y+0.06y=25

0.025y=25-17.5

0.025y=7.5

y=300

Find out the value of x

The distances that the footballs travel before hitting the ground is 50 yards.

For the given question;

The football is kicked by the player.

The second kick is modeled by f(x) = -0.051x(x - 50).

Where, f is the height (in yards) and x is the horizontal distance (in yards).

For calculating the distances that the footballs travel before hitting the ground, Put f(x) = 0.

As, the ball will reach the ground the height of ball above ground will be zero, thus f(x) = 0.

f(x) = -0.051x(x - 50) = 0

Simplifying;

-0.051x² + 2.25x = 0

Or, divide wole equation by x.

0.051x = 2.25

x = 50 yards.

Thus, the distances that the footballs travel before hitting the ground is 50 yards.

Answer:

  y = -7/8x -2

Step-by-step explanation:

You want the slope-intercept equation of the line through the points (8, -9) and (0, -2).

The slope of the line through points (x1, y1) and (x2, y2) is given by the formula ...

  m = (y2 -y1)/(x2 -x1)

For the given points, the slope of the line is ...

  m = (-2 -(-9))/(0 -8) = -7/8

The y-intercept of the line is the y-value when x = 0. The point (0, -2) tells you the y-intercept is -2.

The slope-intercept equation is ...

  y = mx +b . . . . . . where m is the slope, and b is the y-intercept

For a slope of -7/8 and a y-intercept of -2, the equation is ...

  y = -7/8x -2

The rate at which the area of this square increases when the area of the square is 9 cm is 24 cm²/s.

The rate of change is a type of function that describes the average rate at which a quantity decreases or increases with respect to another quantity.

Mathematically, the area of a square can be calculated by using this formula;

A = s²

Where:

Next, we would determine the side length of a square by making s the subject of formula as follows:

A = s²

s = √A

s = √9

s = 3 cm.

By applying chain rule of differentiation, the rate of change (da/dt) in area of this square with respect to time is given by:

dA/dt = 2 × s(t) × ds/dt

dA/dt = 2 × 3 × 4

dA/dt = 24 cm²/s.

The number of bookshelves needed if each bookshelves contain 5 books is 10.

She has 47 books. . She wants to put them all on bookshelves.

Therefore, the number of bookshelves she will need if each shelf holds 5 books can be calculated as follows:

The total number of books she has in her possession is 47 books.

All the books must have a place in the bookshelves.

Each bookshelves can only contain 5 books.

Hence,

let

x = number of bookshelves

Therefore,  the equation to find the number of bookshelves is as follows:

5x = 47

divide both sides by 5

The mid-point of LP is 1.5.

Here we have to find the mid-point of the line LP

L is on -2 on the line and P is on 5.

To find the mid-point we have a formula:

mid-point = (b - a)/2

where a and b are two points between which we have to find the mid-point.

So, mid-point of LP = 5 - (-2) / 2

                                = 7/ 2

                               = 3.5

Now we have to find the value so we will subtract -2 with 3.5.

So the mid-point is 3.5 - 2= 1.5.

Therefore the mid-point of the line LP is 1.5.
