Direct variations can be set up as proportions
5/75 = 8/x....5 hrs to 75 dollars = 8 hrs to x dollars
now we cross multiply
(5)(x) = (75)(8)
5x = 600
x = 600/5
x = 120 <== so he makes $120 for working 8 hrs
another way...
75/5 = 15..so he makes 15 per hr
15 * 8 = 120
Answer:
4695.90
Step-by-step explanation:
The exponential growth function is given as:
y = a(1 + r)^t
a = Initial value = 390
y = Value after time t = ?
r = Growth rate = 5% = 0.05
t = Time in years =51
Hence
y = 390(1 + 0.05)⁵¹
y = 4695.9002123
Approximately = 4695.90
Answer:
8.3 cm
Step-by-step explanation:
So a pentagon has 5 equal sides, and the perimeter is the distance around a figure. Because we know the perimeter is 41.5 centimeters, we just divide that number by 5.
Perimeter (P) = s+s+s+s+s (sides)
P: 41.5 cm ÷ 5 =
8.3 cm
We know this is correct because:
8.3 + 8.3 + 8.3 + 8.3 + 8.3 = 41.5
Hope this helps!
If the volume of this pyramid is 234 units, the height of the pyramid is equal to 13 units.
<h3>How to calculate the volume of a pyramid.</h3>
Mathematically, the volume of a pyramid is given by the formula:
<u>For the </u><u>base area</u><u>:</u>
The area of a right triangle is given by:
A = 54 square units.
<u>Given the following data:</u>
Volume of a pyramid = 234 units.
Side lengths of right triangle = 9 and 12 units.
Now, we can calculate the height of the pyramid:
h = 13 units.
