Step-by-step explanation:
You start by asking yourself or as I call it crossmultiply
if 20 min the bucket is 1/8 full what about 8/8 or a whole
<u>2</u><u>0</u><u>×</u><u>8</u><u>/</u><u>8</u><u>×</u><u>1</u><u>/</u><u>8</u>
=160 min or 2.6 hrs
Here's another one.
See the attached picture.
Answer:
12.56 ft.
Step-by-step explanation:
The formula of the circumference is
C = pi *d where d is the diameter
C = 3.14 *4
C =12.56
You answer would be Oy= 7x-1. I hope this helps!
Answer:
Third option
Step-by-step explanation:
We can't factor this so we need to use the quadratic formula which states that when ax² + bx + c = 0, x = (-b ± √(b² - 4ac)) / 2a. However, we notice that b (which is 6) is even, so we can use the special quadratic formula which states that when ax² + bx + c = 0 and b is even, x = (-b' ± √(b'² - ac)) / a where b' = b / 2. In this case, a = 1, b' = 3 and c = 7 so:
x = (-3 ± √(3² - 1 * 7)) / 1 = -3 ± √2
