______ square feet​

Answer:

The answer is D.5(9a-2b)

Step-by-step explanation:

Step-by-step explanation:

5x9a -5x2b= 45a - 10b

so that is the answer

Answer:

Top row, third one from left to right

Step-by-step explanation:

Use test points:

when x = 0 , y = 2(0) - 4 = 0 - 4 = -4

(0, -4)

when y = 0, 0 = 2x - 4, 4 = 2x, 2 = x

(2, 0)

Top row, third one from left to right

Answer:

x = -1

Step-by-step explanation:

AB + BC = AC = 28

the way from A to C goes through B.

so, the total way of A to C is the sum of the way from A to B and then from B to C.

=>

(5x + 10) + (2x + 25) = 28

7x + 35 = 28

7x = -7

x = -1

Answer:

x = -1

Step-by-step explanation:

5x + 2x + 10 + 25 = 28

7x + 35 = 28

7x = -7

x = -1

Step-by-step explanation:

Answer:

187, 199, 211, 250, 298, 331, 347, 362

[tex]median = {( \frac{n}{2} + 1) }^{th} \: value \\ = ( \frac{8}{2} + 1) {}^{th} \: value \\ = {5}^{th} \: value \\ median = 298[/tex]

Answer:

The median is the middle number in a set of data when the data is arranged in ascending (this is more common) or descending order. If there are an even number of values in the data set, the median is the arithmetic mean of the two middle numbers. Thus, the median separates the lower and higher half of a data set.

Step-by-step explanation:

ascending order : 187, 199, 211, 250, 298, 331, 347, 362

answer: 250, 298 .

Answer:

Step-by-step explanation:

The center of the circle is the midpoint of the two end points of the diameter.

Formula

Center = (x2 + x1)/2 , (y2 + y1)/2

Givens

x2 = 4

x1 = - 10

y2 = 6

y1 = - 2

Solution

Center = (4 - 10)/2, (6 - 2)/2

Center = -6/2 , 4/2

Center = - 3 , 2

So far what you have is

(x+3)^2 + (y - 2)^2 = r^2

Now you have to find the radius.

You can use either of the endpoints to find the radius.

find the distance from (4,6) to (-3,2)

r^2 = ( (x2 - x1)^2 + (y2 - y1)^2 )

x2 = 4

x1 = -3

y2 = 6

y1 = 2

r^2 = ( (4 - -3)^2 + (6 - 2)^2 )

r^2 = ( (7)^2 + 4^2)

r^2 = ( 49 + 16)

r^2 = 65

Ultimate formula is

(x+3)^2 + (y - 2)^2 = 65

The radius is √65 = 8.06

Answer:

x=58 degree

Step-by-step explanation:

angle AGF +32 =90 degree (being perpendicular)

angle AGF =90-32

angle AGF =58 degree

angle x =angle AGF (being vertically opposite angles)

x=58 degree

Answer: It is asking for the answer to angle x, which is 68 degrees

Answer:

Volume of cylinder B = 720 cm³

Step-by-step explanation:

Given:

A and B are similar cylinder

Height of cylinder B = 10 cm

Height of cylinder A = 5 cm

Area of the cross section for cylinder A = 18 cm²

Find:

Volume of cylinder B

Computation:

Area of the cross section for cylinder B = a

So,

(10/5)² = (a/18)

4 = a/18

Area of the cross section for cylinder B = 72 cm²

Volume of cylinder B = Area of the cross section for cylinder B x Height of cylinder B

Volume of cylinder B = 72 x 10

Volume of cylinder B = 720 cm³

$50 is the earned for every sales

$30000 is earned for 30000/50=600

He has to made 600 sales to earn 30000

Answer:

Step-by-step explanation:

This is a right triangle; so you can use the Pythagorean Theorem ([tex]a^2 + b^2 = c^2[/tex]), where a and b are the lengths of the legs and c is the hypotenuse.

You get: [tex]5^2 + 12^2 = c^2[/tex]

Simplify the expression: [tex]25 + 144 = c^2[/tex]

Combine like terms: [tex]169 = c^2[/tex]

Take the square root of both sides: [tex]\sqrt{169} = \sqrt{c^2}[/tex]

Evaluate: 13 = c

So the answer is letter c ... x = 13

Answer:

Step-by-step explanation:

Daisy's mom is 4 times as old as she.

m = 4d

The sum of their ages 6 years ago was 28.

(m - 6) + (d - 6) = 28

Substitute for m = 4d

(4d - 6) + (d - 6) = 28

Combine like terms

5d - 12 = 28

5d = 40

Divide by 5

d = 8

m = 4d

m = 4 * 8

m = 32

Answer:

The second space (13 feet wide & 15 feet long) is the larger space.

Step-by-step explanation:

According to the question,

Thus, The Area Of Rectangle = Length x Width ⇒ 12 × 16 ⇔ 192 Feet² .

Thus, The Area Of Rectangle = Length x Width ⇒ 13 × 15 ⇔ 195 Feet² . Hence it is Clearly Shown here the The second space (13 feet wide & 15 feet long) is the larger space .

Answer:

(5, 0)

Step-by-step explanation:

Se the equations equal

x² - 2x - 15 = 8x - 40

Subtract 8x from both sides

x² - 10x - 15 = -40

add 40 to both sides

x² - 10x + 25 = 0

Factor

(x - 5)(x - 5) = 0

x = 5

---------------

plug in x = 5 into

y = 8x - 40

y = 8(5)- 40

y = 0

-----------------

Solution

(5, 0)

Answer:

The desired single multiplier is 1.26.

Step-by-step explanation:

A 5% increase results in the original amount PLUS 5% of the original amount:

1.05(original amount)

If a 20% increase follows, we must multiply the above 1.05(original amount) by 1.20:

1.20(1.05)(original amount), or (after multiplying), 1.26.

The desired single multiplier is 1.26.

Answer:

-7/45

-4/15+1/9 (two negatives make a plus or addition)

least common multiple of 15 and 9 = 45

 45 is the denominator

15*3=45 , 9*5 = 45

-4*3 = -12 ,1*5 = 5

-12+5 = -7/45

Answer:

-7/45

Step-by-step explanation:

find lowest common denominator: 45 (9 x 5 = 45, 15 x 3 = 45)

[tex]-\frac{4}{15} = \frac{(4*3)}{(15*3)} =-12/45\\\\\frac{1}{9}=\frac{(1*5)}{(9*5)} =5/45[/tex]

subtracting a negative = addition

[tex]-\frac{12}{45} +\frac{5}{45}\\\\=\frac{-12+5}{45} \\\\=-\frac{7}{45}[/tex]

Answer:

a) 60, because in every triangle, the angles always add up to 180. there are three angles in a triangle, and you k is two add to 120, so of you and 60 to 120 you get 180

Answer:

Step-by-step explanation: Let the total no of cars in the collection be X

Number of black cars = (1/4)X

Number of red cars = (5/8)X

Number of white cars= 7

Summation of all the cars,

(1/4)X + (5/8)X + 7 = X

X= 56

Therefore,

Number of black cars = (1/4) of 56 = 14

Number of red cars = (5/8) of 56 = 35

Number of white cars = 7
