Answer:

540 inches equals 45 feet and 15 yards (E,D,F)

Step-by-step explanation:

18 feet = 216 inches

           = 18 feet

           = 6 yards

10 feet = 120 inches

           = 10 feet

           = 3.333 (repeating) yards

540 inches = 540 inches

                   = 45 feet

                   = 15 yards

Answer:

read explanation

Step-by-step explanation:

this is a quadratic equation

first, move the 7x over to the other side so that we have 0 on one side

x^2+7x+12=0

now, we can factor

turn 7x into 3x and 4x, so x^2+3x+4x+12=0

you can turn x^2+3x into x(x+3) and 4x+12 into 4(x+3)

so, our new equation is x(x+3)+4(x+3)=0

that can be turned into (x+4)(x+3)=0 via the distributive property

so, either x+4 or x+3 has to be equal to 0

so, x is either -4 or -3

Answer:

15 cu ft

Step-by-step explanation:

figure A~figure B

4-->2 ft

10-->5 ft

3-->1.5 ft

V=2×5×1.5=15 cu ft

The volume of Figure B is  15 [tex]ft^{3}[/tex]

The RATIO OF SIMILARITY between any two similar figures is the ratio of any pair of corresponding sides. Simply stated, once it is determined that two figures are similar, all of their pairs of corresponding sides have the same ratio.

According to the question

Figure A ≈ Figure B

Therefore , ratio of corresponding sides have the same ratio .

Figure A              Figure B

4 ft                ⇒         2 ft  (given )

( As ratio of [tex]\frac{side\\\ of\\\ figure A}{side\\\ of\\\ figure B} = \frac{2}{1}[/tex] )

10 ft                ⇒        5 ft

3 ft                ⇒         1.5 ft

Now, volume of Figure B (which is cuboid ) =  Length * Breath * Height

                                                                       =  2 * 5 * 1.5

                                                                       =    15 [tex]ft^{3}[/tex]

Hence, the volume of Figure B is  15 [tex]ft^{3}[/tex]

Answer:

x = 8

y = 14

Step-by-step explanation:

2x + 6 = 4x - 10 (Corresponding angles so they're equal)

2x - 4x = -10 - 6

-2x = -16

x = 8

2x + 6 + 13y - 24 = 180 (Supplementary angles so they add up to 180)

2(8) + 6 + 13y - 24 = 180

16 + 6 + 13y - 24 = 180

13y - 2 = 180

13y = 182

y = 14

Answer:

Step-by-step explanation:

Since r=2 and |r|>1 the sum does not converge to any value. The sum does not exist for this infinite geometric series.

The sum to infinity of the sequence is -18

The formula for calculating the sum to infinity of a geometric sequence is expressed as:

Sinfty = a/1-r

where

a is the first term

r is the common ratio

From the nth term

a = 18

r = 2

Substitute

Sinfty = 18/1-2

Sinfty = -18

Hence the sum to infinity of the sequence is -18

sample 1=1 rock=1,200songs

Answer:

A' = 103°

B' = 100°

C' = 80°

D' = 77°

Step-by-step explanation:

B' = 180 - 80 = 100°

C' = 80 because it is a corresponding to 80°

D' = 180 - 125 = 55, 180 - 48 - 55 = 77°

A' = 360 - 77 - 100 - 80 = 103°

Answer:

The recommended number of flowers is 32

Step-by-step explanation:

Given

The attached graph

Required

The number of flowers when area = 15

First, calculate the slope (m)

Considering

[tex](x_1,y1) = (12,60)[/tex]

[tex](x_2,y_2) = (15,20)[/tex]

[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

[tex]m = \frac{20-16}{15-12}[/tex]

[tex]m = \frac{4}{3}[/tex]

Considering:

[tex](x_1,y_1) = (15,20)[/tex]

[tex](x_2,y_2) = (24,y)[/tex]

The slope is:

[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

[tex]m = \frac{y - 20}{24 - 15}[/tex]

[tex]m = \frac{y - 20}{9}[/tex]

Recall that: [tex]m = \frac{4}{3}[/tex]

So:

[tex]\frac{4}{3} = \frac{y - 20}{9}[/tex]

Multiply through by 9

[tex]3*4 = y - 20[/tex]

[tex]y = 20 + 3 * 4[/tex]

[tex]y = 32[/tex]

Answer:

89

Step-by-step explanation:

So we need to find the area of the triangle. We already know that the individual two triangles height is 6 and so we need to find the width. The top is 13m and we know that 4m+4m is 8. 13-8 would be 5, and 5/2 (because there are two right triangles) is 2.5

After that, we can find 2.5 times 6 would be 15. We don't need to divide by two because we'll just have to multiply again because there are two triangles.

After that, we can find the area of the figure. 8 times 13 would be 104. 104-15 would be 89. That is the area of the figure, 89.
