Step-by-step explanation:
<u>Substitute the value of y into the equation;</u>
Find the value of x.
<u>Multiply;</u>
<u>Add 8 to </u><u>each</u><u> side;</u>
<u>Divide </u><u>each</u><u> side by 8;</u>
Answer:
x =5
Step-by-step explanation:
c = 5√2
a = x
b = x
Formula
x^2 + x^2 = c^2 Combine the x^2
Solution
2x^2 = (5√2)^2 Expand the right side
2x^2 = 2*25 Divide both sides by 2
x^2 = 25 Take the square root of both sides.
x = 5
Answer:
A= ~2.55
Step-by-step explanation:
Using Pemdos, or gemdos, you can find you do the exponent first
4^2 = 16
then to everything else in left to right order since they're all multiplication or division
22/7 = ~3.14 * 13 = ~40.86/16 = ~2.55
(I'm using "~" to mean about/rounded to)
Answer:
- C. π(3in)2(12in) − 9(four over threeπ(1.5in)3)
Step-by-step explanation:
Volume of water is the difference of volume of vase at 12 in height and the total volume of marbles.
<u>Volume of cylinder up to water level:</u>
- Vs = πr²h = π(6/2)²(12) = π×(3 in)²×(12 in)
<u>Volume of marbles:</u>
- Vm = 9(4/3πr³) = 9×(4/3×π(3/2)³) = 9×(4/3×π×(1.5 in)³)
<u>Volume of water:</u>
- Vw = Vs - Vm = π×(3 in)²×(12 in) - 9×(4/3×π×(1.5 in)³)
Correct choice is C
