The perimeter of a rectangle is twice the sum of its side lengths.

P=2(L+W), we are told that L=3W and P=176 so

2(3W+W)=176

2(4W)=176

8W=176

W=22 ft, since L=3W

L=66 ft

So the yard is 22 feet wide and 66 feet long.

P = 2(L + W)
L = 3W
P = 176

176 = 2(3W + W)
176 = 2(4W)
176 = 8W
176/8 = W
22 = W <=== width

L = 3W
L = 3(22)
L = 66 <===length

If (he)={(0,1),(2,3),(-4,1)}, find h^-1(x)

ololo11 [35]

The given function is

$h(x) = \{ (0,1), (2,3), (-4, 1) \}$

The inverse function is

$h^{-1}(x) = \{ (1,0), (3,2), (1,-4)\}$

To get the inverse, we swap each x and y coordinate.

The rule is $(x,y) \to (y,x)$

So that's why the point (0,1) becomes (1,0) for instance.

Answer:

raise a product to a power.

you first simplify the parenthesis in the numerator by raising 2 by the power of three and multiplying the exponents.

i suck at explaining, but after the first step the expression looks like:

$(\frac{8r^{6}t^{3} }{4t^{2} })^{2}$

7. Nick’s youth group has 20 regular students that attend weekly get togethers. They saved up enough money for each person to go

Anna11 [10]

Answer:

If each youth saves $10 daily, their weekly savings would be $1400. So they donated $1400 to the church.

Step-by-step explanation:

Let the daily pay plan for each youth be $y

Daily pay plan for 20 youth = $20y

Weekly pay plan = 7×20y = $140y

Assuming each youth saves $10 daily

Daily savings for 20 youth = 20×$10= $200

Weekly savings for 20 youth = 7×$200= $1400

If they used the early pay plan ($140y) to go swimming, they saved $1400 which they donated to the church.
