4x+4=-3+2x+15
Step 1: combine like terms
4x-2x=15-3-4
2x=8
Step 2: divide by 2 on both sides
x=4
Answer:
4000π cm^2
Step-by-step explanation:
first we change the 1.6m to cm:
1.6m = 160cm
Now we can use the formula:
V = πr^2h
where π is just π, r is the radius (not the diameter) and h is the height
V = π * 5^2 * 160 = 4000π cm
A) The number 0.66666667 as fraction is = ![\frac{66666667}{100000000}](https://tex.z-dn.net/?f=%5Cfrac%7B66666667%7D%7B100000000%7D)
B) 32 students prefer granola bars over muffins.
The total number of classmates = 48
The probability that a student says yes = 0.66666667
Note that 0.66666667 can also be written as ![\frac{0.66666667}{1}](https://tex.z-dn.net/?f=%5Cfrac%7B0.66666667%7D%7B1%7D)
To convert 0.66666667 to fraction, multiply both the numerator and the denominator by 100000000
The probability that a student says yes = ![\frac{66666667}{100000000}](https://tex.z-dn.net/?f=%5Cfrac%7B66666667%7D%7B100000000%7D)
Therefore, the number 0.66666667 as fraction is = ![\frac{66666667}{100000000}](https://tex.z-dn.net/?f=%5Cfrac%7B66666667%7D%7B100000000%7D)
Number of students that prefer granola bars over muffins = 0.66666667 x 48
Number of students that prefer granola bars over muffins = 32
Therefore, 32 students prefer granola bars over muffins.

Answer:
<h3>1/4</h3>
Step-by-step explanation:
Given
amount of salamanders, = 5
amount of crayfish = 3
amount of minnows = 12
Total fish = Total outcome = 5+3+12
Total outcome = 20
Since we are looking for the probability of selecting salamanders, our expected outcome will be 5.
Probability = expected outcome/total outcome
Pr( salamanders,) = 5/20
Pr( salamanders) = 1/4
Hence the probability of selecting salamanders, is 1/4
