Answer:
Step-by-step explanation:
Assuming each person gets the same amount of work done, each wall in the first scenario takes 8 minutes to paint. If 3 people paint 4 walls, then each person is painting 1 1/3 of a wall. We can use that to find out how long it takes one person to paint 1 1/3 walls:
. Interpreting that, it takes each person 10 2/3 minutes to paint 1 1/3 walls.
If 4 people paint 7 walls, that means that each person is painting 7/4 walls, or 1.75 walls each. Using the fact that it takes 10.66666 minutes to paint 1.33333 walls, we can find out how many minutes it will take to paint 1.75 walls:
Cross multiply to get
18.666655 = 1.3333x so
x = 14.000 minutes
Answer:
1/6
Step-by-step explanation:
To find the value of x that makes the equation true we isolate x on one side of the equation. Technically this is solving for x. The Division Property of Equality states that if we divide both sides of an equation by the same amount then we will have an equivalent equation. We can divide both sides of this equation by 36 to get x = 1/6
Answer:
17
Step-by-step explanation:
The point plotted is 4.1. In order to find what it is the square root of, you need to square it:
4.1^2 = 16.81 ≈ 17
We have that
1/16 = 64<span>^x
applying log both sides
log(1/16)=log(</span>64^x)
log 1-log16=x*log64
-log 16=x*log 64
divide by log 64 both sides
x=-log 16/log 64
log 16=log 2^4-----> 4*log 2
log 64=log 2^6-----> 6*log 2
-log 16/log 64=(-4*log 2)/(6*log 2)-----> -4/6------> -2/3
the answer is
x=-2/3
