Which equation represents a line which a perpendicular to the line y=4x-7?​
jasenka [17]

Answer:

-1/4

Step-by-step explanation:

The slope-intercept form is  y = m x+b ,

where  m  is the slope and  b  is the y-intercept.

y = m x + b

Using the slope-intercept form, the slope is  4.

4  m = 4

The equation of a perpendicular line to  

y = 4 x - 7

must have a slope that is the negative reciprocal of the original slope.

− 1 /4

Math help please show work thanks

Problem 5

d = 29 = diameter

r = d/2 = 29/2 = 14.5 = radius

SA = surface area of sphere

SA = 4*pi*r^2

SA = 4*pi*(14.5)^2

SA = 841pi

SA = 841*3.14

SA = 2,640.74 square inches

To convert from square inches to square feet, we divide by 144. This is because 12^2 = 144.

2,640.74 square inches = (2,640.74)/144 = 18.3 sq ft

<h3>Answer: 18.3 square feet (approximate)</h3>

=====================================

Problem 6

d = 10.7 = diameter

r = d/2 = 10.7/2 = 5.35 = radius

L = 22.3 = slant height

SA = surface area of the cone

SA = pi*r^2 + pi*r*L

SA = pi*(5.35)^2 + pi*5.35*22.3

SA = 147.9275pi

SA = 147.9275*3.14

SA = 464.49235

<h3>Answer:  464.49235 square cm (approximate)</h3>

Khloe made 20% of her free throws over the season. If she shot 240 free throws, how many did she make?
Butoxors [25]
20% is the same as saying 0.2, so if you multiply 0.2 by 240, you should get your answer. Or an alternate way of seeing it is 2 times 24.
