Answer:
We have l = 2w and 2l + 2w = 100 inches;
Then 4w + 2w = 100 inches;
6w = 100 inches;
w = 16.6;
l = 3 x 16.6;
l = 49.8 inches;
Step-by-step explanation:
Answer:
x = 10
Step-by-step explanation:
Since L is the midpoint
KL = LM
2x-3 = x+7
Subtract x from each side
2x-3-x = x+7-x
x-3 = 7
Add 3 to each side
x-3+3 = 7+3
x = 10
Answer:
The time it will take the population to grow to 800 insects is 17 days.
Step-by-step explanation:
The growth function of the insects is exponential.
The exponential growth function is:

Here,
<em>y</em> = final value
<em>a</em> = initial value
<em>r</em> = growth rate
<em>t</em> = time taken
It is provided that there were 270 insects after 9 days and initially there were 80 insects.
Compute the value of <em>r</em> as follows:

Now, compute the time it will take the population to grow to 800 insects as follows:

Thus, the time it will take the population to grow to 800 insects is 17 days.
Answer: 7
Step-by-step explanation:
Since we are given the information that a group of friends had 28 driveways to shovel and that one of them shoveled 1/4 of the driveways.
The number of driveways that he shovel will be:
= 1/4 × 28
= 7
Therefore, he shovel 7 driveways.
Answer:
14 square units
Step-by-step explanation:
If you graph the points your triangle's height will be 4, and base would be 7.
<em>A = 1/2bh 4</em> x 7 = 28, 28 x 1/2 = 14.
Hope this helps :D
