Answer:

area is 180

Step-by-step explanation:

Answer:

TQ = 24

Step-by-step explanation:

Δ RST and Δ RPQ are similar, thus ratios of corresponding sides are equal, that is

[tex]\frac{RS}{RP}[/tex] = [tex]\frac{RT}{RQ}[/tex] , substitute values

[tex]\frac{15}{35}[/tex] = [tex]\frac{18}{RQ}[/tex] ( cross- multiply )

15 RQ = 630 ( divide both sides by 15 )

RQ = 42

Then

TQ = RQ - RT = 42 - 18 = 24

Answer:

length is 32

formula of finding the length of square is 92 divided by 3

32

area is 1024

the formula of finding area is Lenght multiply by length

so 32 multiply by 32

1024

Given:

Grocery store located at point (5,-4).

Park is located at point (-5,4).

Paula's house is halfway between the Grocery store and park.

School is halfway between the Paula's house and park.

To find:

Ordered pair for the school.

Solution:

Formula used:

[tex]\text{Midpoint}=\left(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2}\right)[/tex]

Paula's house is halfway between the Grocery store and park. It means the location of Paula's house is the midpoint of (5,-4) and (-5,4).

[tex]\text{Paula's house}=\left(\dfrac{5+(-5)}{2},\dfrac{(-4)+4}{2}\right)[/tex]

[tex]\text{Paula's house}=\left(\dfrac{0}{2},\dfrac{0}{2}\right)[/tex]

[tex]\text{Paula's house}=\left(0,0\right)[/tex]

So, the Paula's house is located at (0,0).

School is halfway between the Paula's house and park. It means the location of the school is the midpoint of (0,0) and (-5,4).

[tex]\text{School}=\left(\dfrac{0+(-5)}{2},\dfrac{0+4}{2}\right)[/tex]

[tex]\text{School}=\left(\dfrac{-5}{2},\dfrac{4}{2}\right)[/tex]

[tex]\text{School}=\left(-2.5,2\right)[/tex]

Therefore, the correct option is B.

Answer:

18= -6x+11

19= 2(x+1)

20= 11x+2

Answer:

[tex](x-0)^{2} + (y-5)^{2} = 25[/tex]

Step-by-step explanation:

The "template" equation of a circle is:

[tex](x-h)^{2} + (y-k)^{2} = r^{2}[/tex]

All you're doing after that, is filling in the blanks:

h = 0

k = 5

r = 5

Answer:

Correct answer:

(x−0)² + ( y−5)²=5²

Explanation:

The equation of a circle is (x−h)²+(y−k)²=r²

The center is (0,5) or, written another way (h,k). Substituting 0 for h and 5 for k, our formula becomes (x−0)²+(y−5)²=5²

Finally, the formula of the circle is (x−0)²+(y−5)²=25

Answer:

15.21

Step-by-step explanation:

All of the bills total to $2432.50. The person works 160 hours in a month. $2432.50 ÷ 160 = $15.20, BUT:

$15.20 × 160 = $2432, which is 50 cents short of what they need, so one extra cent in their wage will give them the amount they need.

$15.21 × 160 = $2433.60

Answer:

(-2,2)

Step-by-step explanation:

Substitute answer for y in first equation (y=x + 4) into y of second equation

x+4=-2x-2

3x=-6

x=-2

put value of x (-2) into either equation to solve for y

y=x+4

y=-2+4

y=2

or y=-2x-2

y=-2(-2)-2

y=4-2

y=2

Answer:

The Blue Tile covers more area by 40 mm^2

Step-by-step explanation:

convert centimeter  to  millimeters

1cm = 10 mm

(6 x 10) by (8 x 10)

Area of a rectangle = length x breadth

60 x 80 = 4800

70 x 68 = 4760

difference = 4800 - 4760 = 40

Answer:

12 inches in 1 foot

Step-by-step explanation:

In this problem, we need to find an example that is a scale.

There must be a relation between two units.

There are many types of units of lengths. These can be metre, cm, mm, foot, inches.

The relation between inch and foot is given by :

1 foot = 12 inch

So, we can say there are 12 inches in 1 foot.

Hence, the correct option is (c).

Answer:

Step-by-step explanation:

× A = 4y + 2 = 2(4y/2 + 2/2) = 2(2y + 1) ≠ 4(y + 2)

✓ B = 4y + 8 = 4(4y/4 + 8/4) = 4(y + 2) = 4(y + 2)

× C = y + y + y + y + 2 =

y (1 + 1 + 1 + 1) + 2 = 4y + 2 = A ≠ 4(y + 2)

✓ D = 5(y + 2) – (y + 2) = 5(y + 2) – 1(y + 2) =

(5 – 1)(y + 2) = 4(y + 2)

✓ E = y + y + y + y + 2 + 2 + 2 + 2 =

y (1 + 1 + 1 + 1) + (2 + 2 + 2 + 2) =

4y + 8 = B = 4(y + 2)

× F = 5(y + 2) – (y – 2) =

(5y + 10) + (-y + 2) =

(5y – y) + (10 + 2) =

4y + 12 = 4(y + 3) ≠ 4(y + 2)

Answer:

80%of 25 is 20

Step-by-step explanation:

Answer:

20

Step-by-step explanation:

To solve we must first find what 80% is in decimal form.

to do this we can move the decimal place to the left 2 spots

80% ---> 0.80

We can now multiply this decimal by 25

25 × 0.80 = 20
