F = 9/5(40) + 32
F = 72 + 32
F = 105
40°C is ~105°F, and the closest would be D.
10.25 hours on average
8+12+12+9=41
41/4= 10.25
Answer:
E
Step-by-step explanation:
19) Amount of oil in = amount of oil in final product
.025(x) + .09(40-x) = .055(40) (x = 2.5% amt 40 - x = 9% amt)
x = 21.54 L of 2.5 % then 9% = 18.46 L
Make it a fraction
7/25 * 4/4 = 28/100
0.28 = 28 percent
There is a 28 percent chance the next marble will be red
