Answer:

Width= 85

Length= 485

Step-by-step explanation:

The width will be x, and the length will be x + 400, since it is 400 more than the width.

We know that the perimeter of a rectangle can be found using the equation 2w + 2l.

We plug in the values we have found.

2(x) + 2(x+400) = 1140

4x + 800 = 1140

4x = 340

x = 85

Now we know the width, since it is simply x. To find length all we have to do is add 400.

400 + 85 = 485

A rectangle has a width of 6 inches and a perimeter of 26 inches. What is the length of the rectangle?
labwork [276]

Answer:

Length = 7 inches

Step-by-step explanation:

Perimeter = 2L+2W

Perimeter = 26

W = 6

Plug these in: 26=2L + 2*6 ; 26 = 2L + 12

Subtract 12 from both sides.

26-12 = 2L +12 -12 ; 14 = 2L

Devide by 2

14/2 = 2L/2

L=7

Are the graphs of 6 <br>y = -2x + 4 and y = 6x - 4 parallel perpendicular or neither
timurjin [86]
1st slope is -1/3. 2nd slope is 6

slope is same in parallel lines so not parallel

slopes are negative reciprocals in perpendicular lines so they aren't perpendicular

they are called oblique

The population of a certain species of bird in a region after t years can be modeled by the function P(t)= 1620/1+1.15e^-0.042t
natka813 [3]

Answer:

A

Step-by-step explanation:

The function is  \frac{1620}{1+1.15e^{-0.042t}}

To find the maximum population, we need to set t towards infinity to get our answer.

So, we replace time with maximum (\infty). Let's check:

\frac{1620}{1+1.15e^{-0.042t}}\\=\frac{1620}{1+\frac{1.15}{e^{0.042t}}}\\=\frac{1620}{1+\frac{1.15}{e^{0.042(\infty)}}}\\=\frac{1620}{1+\frac{1.15}{\infty}}\\=\frac{1620}{1+0}\\=\frac{1620}{1}\\=1620

The population of birds approaches 1620 as t goes towards infinity. So we can say the max population of the species is 1620.

Correct answer is A

Mom has ⅘ quart of strawberries. She needs to fill ¼-quart jars. How many jars will she be able to fill?
Blababa [14]
She will be able to fill 3 jars because 4/5=16/20 and 1/4 = 5/20 so 5/20 x 3 = 15/20
