Anna71 [15]

Answer:

Length = 120 ft

Total cost = 1500$

Step-by-step explanation:

First, to find the length of the backyard we reverse the formula (A = l * w) and divide 10,800 by 90.

10,800 ft^2 / 90 ft = 120 ft.

we can check this by plugging the length of 120 ft into the formula:

120 ft * 90 ft = 10,800 ft^2.

Next, to find the cost of the single length of fence we multiply our length (120 ft) by the cost ($12.50):

120 * 12.50 = $1500

Step-by-step explanation:

The solution to a system of equations are the point(s) where the graphes intersect. On the graph is a linear function and an exponential. Because of the curve in the exponential, the graph has two solutions at (-6,3) and (-4,-5).

5 cats each ate 1/4 cup of cat food. Four other cats each ate 1/3 cup of cat food. How much did the nine cats eat?

serg [7]

<u>ANSWER</u>

Number of cups consumed by five cats

$=5\times \frac{1}{4}$

$= \frac{5}{4}$ cups.

Number of cups consumed by four cats

$=4\times \frac{1}{3}$

$= \frac{4}{3}$ cups.

Number of cups consumed by all nine cats

$=\frac{5}{4} + \frac{4}{3}$

The LCM is 12. So we collect LCM to get;

$= \frac{5\times 3+4\times4}{12}$

$= \frac{15+16}{12}$

$= \frac{31}{12}$

$=2 \frac{7}{12}$ cups
