Answer:
Step-by-step explanation:
This is an inverse proportion.
men = k / Time So first we need to find k
k = men * Time Substitute values
k = 15*80
k = 1200 Notice the units are man days.
Now what happens if we increase the number of men to 20? What happens to the number of days.
20 = 1200 / time Multiply both sides by time
20*time = 1200 Now divide by 20
time = 1200/20
Answer: time = 60 days
Hey!
To find the area of Jamal's bed, we must multiply the dimensions together:
27 × 36 = 972
So, the area of the bottom of his bed is 972 square inches.
Angle G is common to both of the triangles.
Answer:
Step-by-step explanation:
Hi there,
To solve this problem, we will need to isolate the variable by moving the variable to one side and the number to the other side.
1. - 16.5v - 19.94 = 19.39 - 9.6v <em>Rewrite the problem</em>
2. - 16.5v = 39.33 - 9.6v <em>Move the non-variable number to one side</em>
3. -6.9v = 39.33 <em>Isolate the variable</em>
4. v = - 5.7 <em>Divide by -6.9</em>
Thus, we can see the answer to this problem is v = - 5.7.
Have a good day,
