If a square piece of land is 20m long, how much cord is needed to go around it 5 times​
pav-90 [236]

Answer:

You will need 400 meters of cord.

Step-by-step explanation:

Since it's a square, we know the perimeter of the piece of land is 20 times 4, or 80. Because it is going around it 5 times, we just multiply 80 by 5 to get 400. You will need 400 meters of cord.

The sum of 1/9, 2/3, and 5/18is<br><br> A. 8/30.<br> B. 12/9.<br> C. 19/18.<br> D. 4/15.
mafiozo [28]
The least common multiple of 9, 3, and 18 is 18.

Convert 1/9 to 2/18.

Convert 2/3 to 12/18.

Then add the numerators:

2 + 12 + 5 = 19

So the answer is 19/18, or 1 1/18 if you prefer.

Anna11 [10]

Answer:

y(t) = \$1900*1.0375^t

Step-by-step explanation:

If y is the future value of the $1900 investment, in dollars, after t years at a rate of 3.75% per year, compounded annually. The exponential function that describes the relationship between the variables y and t is:

y(t) = \$1900*(1.0375)^t

This relationship means that for every year t, the amount y will increase by a factor of 1.0375.

Given the function h(x)=x^2-7x+6h(x)=x
Goryan [66]

Answer:

0 (no change)

Step-by-step explanation:

Recall that the average rate of change of a function f(x) over the interval [a,b] is equal to \frac{f(b)-f(a)}{b-a}:

\frac{h(b)-h(a)}{b-a}\\ \\\frac{h(6)-h(1)}{6-1}\\\\\frac{0-0}{5}\\ \\0

Hence, the average rate of change of the function h(x) over the interval [1,6] is 0, or no change.
