Answer:
<h2>4 and 8</h2>
Step-by-step explanation:
4 and 8 are corresponding angles as they form at parallel lines cut by a transversal.
4 and 3 are supplementary angles (they both add up to 180°).
4 and 1 are vertically opposite angles and are equal to each other.
<u>From the above explanations, only 4 and 8 are corresponding angles. </u>

Answer:
75 minutes
Step-by-step explanation:
In this question, we are asked to calculate the time it will take a smaller hose out of two hoses to fill a swimming pool by itself.
Firstly, let’s say the volume of the swimming pool to fill is Xm^3.
Hence for both, the rate of filling is x/30 m^3/minutes. For the larger hose, rate will be x/50 m^3/minutes. For the larger hose, let the time taken be z minutes. It’s rate will be x/z m^3/minute.
Mathematically, adding both rates together give the rate of both at the same time. This means;
X/30 = x/50 + x/z
X/z = x/30 - c/50
x/z = 20/1500
x/z = 1/75
z = x/75
This means the time that it will take the smaller hose will be 75 minutes
Step 1: Simplify 0.02 x 0.789 to 0.01578
0.01578 ÷ 3.0999
Step 2: Simplify 0.01578 ÷ 3.0999 to 0.0051
0.0051
Done! :) Decimal Form Would Be 0.0051
9=3^2
3^(2x)=(3^2)^(3x-4)
3^(2x)=3^(6x-8)
2x=6x-8
0=4x-8
8=4x
2=x

Amount = $400
Interest rate = 4% a year
----------------------------------------------------
Equation
----------------------------------------------------
Total amount = 400 + 0.04(400)
Total amount = 400 + 16
Total amount = $416
----------------------------------------------------
Answer: Total Amount = 400 + 0.04(400)
