Equation a: 3x y = 6 equation b: 6x - 2y = 4 equation c: y = 3x - 2 equation d: y = 1/3x 7 which two lines are perpendicular?

1 answer:

7 0

Perpendicular have slopes that multil to -1
for
ax+by=c
slope=-a/b

and

y=mx+b
m=slope

equations find slope
A. -3/1=-3
B. -6/-2=3
C. 3
D. 1/3

1/3 times -3=-1

A and D

C is the answer

What is the approximate volume of a cylinder with a diameter of 12 meters and a height of 7 meters? Use 3.14 for pi.

storchak [24]

The mathematical equation for volume of a cylinder is pi times radius Squared Times height

The radius squared is 36

So 3.14 x 36 =113.04
Then you multiply 113.04 x 7 = 719.28.
Round that number and you get to 791.3.

So the answer is c

it takes Joey 1/16 of an hour to write one Thank you card how many cards can he write in 3/4 of an hour?

bearhunter [10]

To solve this problem you will need to use the cross product method:

1/16 of an hour → write 1 card

3/4 of an hour → write X cards

(3/4) ÷ (1/16) = X

0.75 ÷ 0.0625 = X

12 = X

Joey can write 12 Thank you cards in 3/4 of an hour.

There you go! I really hope this helped, if there's anything just let me know! :)
