Answer:

x=2\frac{2}{3}

Step-by-step explanation:

divide both size by 3

⇒\frac{3x}{3}=\frac{8}{3}

3 will cancel 3x then x will stand on it own

x=\frac{8}{3}

3 will divide 8

x=2\frac{2}{3}

The answer is -8/3. first you set it equal to zero, subtract 8 from both sides you get 3x=-8, divide both sides by 3 and you get -8/3

I think starting from the top it would go as follows

9/36, 27/36, 32/36 , 4/36

b.) 9/36

c.) I really don't remember how to do the "order doesn't matter" thing anymore, so idk. my best idea is for you to look up the formulas for permutation and combinations. I know it has to do with that

forsale [732]
<h3>Answer:</h3>

133 ft

<h3>Step-by-step explanation:</h3>

Given in the question,

length of the rectangle = 31 ft

width of the rectangle= 20 ft

diameter of semicircle = 20 ft

radius of semicircle = 20/2 ft = 10 ft

<h3>Formula to use:</h3>

perimeter of rectangle + perimeter of semicircle

perimeter of rectangle = 2(l+w)

perimeter of semicircle = 1/2(2πr)

<h3>Plug values in the formula above</h3>

2(31 + 20) + 3.14(10)

133.4 ft

≈ 133 ft

olya-2409 [2.1K]
Use the formula of the present value of an annuity ordinary which is
Pv=pmt [(1-(1+r/k)^(-kn))÷(r/k)]
Pv present value 5500
PMT monthly payment?
R interest rate 0.115
K compounded monthly 12
N time 5years
Solve the formula for PMT
PMT=Pv÷ [(1-(1+r/k)^(-kn))÷(r/k)]
PMT=5,500÷((1−(1+0.115÷12)^(
−12×5))÷(0.115÷12))
=120.95

So the answer is C

Hope it helps!
