Answer:

y=x+12

Step-by-step explanation:

y=-x+12; is a line with slope m1=-1

to find perpendicular slope of intersecting line take the negative inverse of m1. so -1*(1/(-1))=1=m2

use equation for a line of y=m*x+b and put in the point (-5,7) and solve for b=the y axis intercept

7=1*(-5)+b

7=-5+b

12=b

y=x+12

The diameter of a sphere is 2,160 mm. The diameter of a second sphere is 7,520 mm. Approximately how many times larger is the vo

fgiga [73]

Answer:

Approximately 42 times larger

Step-by-step explanation:

The diameter of a sphere is 2,160 mm.

The diameter of a second sphere is 7,520 mm.

To see how many times larger is the diameter of second sphere is than the diameter of the second sphere, we divide to get:

$k = \frac{7520}{2160}$

$k = 3.481$

To see how many times larger the volume is, we cube both sides

${k}^{3} = {3.481}^{3}$

This implies that

${k}^{3} = 42.181$

Therefore the volume of the second sphere is approximately 42 times larger

Alexandra [31]

Answer:

The answer is 743.4 square inches

Step-by-step explanation:

1. find the length- 2 x 40=80 cm

2. find the width- 1.5 x 40= 60cm

3. find area (Length x width)- 80 x 60= 4800 square cm

4. find length but in inches- 1in=2.54cm length=80/2.54 = 31.5 inches

5. find width but in inches- width= 60/2.54= 23.6 inches

6. Find area(length x width)- 31.5 x 23.6= 743.4 square inches
