It works out that: y = 1 or 5 and therefore x = 5 or 1
Answer:
<u>14762 ft³</u>
Step-by-step explanation:
<u>Volume of top prism</u>
- V = 61 x 8 x (19 - 3)
- V = 488 x 16
- V = <u>7808 ft³</u>
<u />
<u>Volume of bottom prism</u>
- V = 61 x 38 x 3
- V = 183 x 38
- V = <u>6954 ft³</u>
<u />
Total volume = Volume (top) + Volume (bottom)
- 7808 + 6954
- <u>14762 ft³</u>
If solving for Y; divide by 8 to get you by self. also divide 12ty by 8.
y=12/8ty
reduce
y= 3/2ty
Answer:
<h3>x = 21/10y</h3>
Step-by-step explanation:
If the variables x and y vary inversely, this is expressed as;
x ∝ 1/y
x = k/y
k is the constant of proportionality
Given;
x = 7/2 and y = 3/5
Substitute;
7/2 =k/(3/5)
Cross multiply
k = 7/2 * 3/5
k = 21/10
Substitute the value of k into the formula;
x = k/y
x = (21/10)/y
x = 21/10 * 1/y
x = 21/10y
Hence the equation relating x and y is x = 21/10y
