Answer:

YR = 33.6 in.

Step-by-step explanation:

△DLZ∼△MYR

LZ / DZ = YR / MR

21/18 = YR / 28.8

7 / 6 = YR / 28.8

YR = 7 * 28.8 / 6

YR = 33.6

The volume of the Apple iPad Mini 2 is 12.561 in³.

The new volume of the  Pear-Apple is  24.53 in³.

The new volume of the  Pear-Apple is 5.3in³.

The scale factor to have a volume that is half that of the iPad Mini is 0.79.

The scale factor to have a volume that is double that of the iPad Mini is 1.26

<h3 /><h3>What is the volume of the Apple iPad Mini 2?</h3>

Volume = length x width x height

7.9 x 5.30 x 0.30 = 12.561 in³

<h3>What is the volume after the scale factors are applied?</h3>

Dimensions after the 1.25 scale factor is applied: (1.25 x 7.9) x (1.25 x 5.30) x (1.25 x 0.3)

= 9.875 x 6.625 x0.375 = 24.53 in³

Dimensions after the 0.75 scale factor is applied: (0.75 x 7.9) x (0.75 x 5.30) x (0.75 x 0.3)

= 5.925 x 3.975 x 0.225 = 5.3in³

Scale factor to have a volume that is double that of the iPad Mini : 2^{1/3} = 1.26

Scale factor to have a volume that is half that of the iPad Mini : 0.5^{1/3} = 0.79

Answer:

38

Step-by-step explanation:

Given that,

x = -4

f(x)=x² - 4x +6

so,

f(-4)= (-4)² - 4 . (-4) +6

       =16 +16 +6

        = 38

A moving company charges $40 plus $0.25 per mile to rent a van. Another company charges $25 plus $0.35 per mile to rent the same
Bond [772]
<h3>Answer:</h3>

c. 150 miles

<h3>Step-by-step explanation:</h3>

You want to find the number of miles (m) that make the charges equal.

... 40 +0.25m = 25 + 0.35m

... 15 = 0.10 m . . . . . . add -25-0.25m

... 150 = m . . . . . . . . . divide by the coefficient of m

For 150 miles, the rental cost will be the same for both companies.
