45, Because all of the ratios between the numbers are 4/3
your left with the equation 60/x=4/3, now simply solve for x.
60/x=4/3 multiply by x
60=4x/3 multiply by 3
180=4x divide by 4
x=45
Answer:
7
Step-by-step explanation:
Perpendicular lines will have negative reciprocal slopes. Example : if u r given a slope of 1/3, to find the negative reciprocal, flip the slope and change the sign. So the negative reciprocal of 1/3 is -3/1 or just -3. So slope 1/3 and slope -3 are perpendicular.
==================
equation 2 :
4x + 2y = 6
2y = -4x + 6
y = -2x + 3...the slope here is -2....a perpendicular line will have a slope of 1/2.
y = (a/3)x - 6......so we have to make a/3 = 1/2......1.5/3 = 1/2
so a = 1.5
===================
eq. 2 : 3/4x + 2
not sure what the entire equation is.....but it looks to have a slope of 3/4. That means a perpendicular line will have a slope of -4/3.
3y + ax = 9
3y = -ax + 9
y = (-a/3)x + 3.....therefore, a has to be 4
The orientation of the solid is odd, but here is what I see.
24+24+39+52+65= 204 units^2
We are told that 21% of the total cans is 63 cans, therefore
100% of all the cans collected would be.
(63*100)/21=300 cans were collected in all
