1. Divide by 4
sqrt 2x+8 = 6
2. Square both sides to remove square root
2x+8 = 36
3. Subtract 8
2x = 28
4. Divide by 2 to make x by itself
x = 14
Answer: 3 fluid ounces
Step-by-step explanation:
The family size bottle of shampoo holds 10 fluid ounces of sunscreen while the regular bottle holds 70% percent less.
To get the fluid ounces the regular bottle of shampoo will hold, we find 70% of 10 fluid ounces and them subtract from 10 fluid ounces. This will be:
= 70% of 10 ounces
= 7/10 × 10
= 7 fluid ounces.
Since the regular holds 70% less, week subtract 7 fluid ounces from 10 fluid ounces. This will be:
= 10 ounces - 7 ounces
= 3 ounces.
The regular bottle of shampoo holds 3 fluid ounces.
Answer:
Step-by-step explanation:
We have been given that Courtney had 15 hits in 60 at bats.
We know that batting average can be determined by dividing hits by number of at-bats.
Therefore, Courtney's batting average is 0.25.
We are already told that Katie's average was 0.300. Therefore, Katie's batting average is 0.300.
We have been given that Sara got a hit 32.5% of the time. To find Sara's batting average, we need to convert 32.5% into decimal as:
Therefore, Sara's batting average is 0.325.

Answer:
x = 2√3 ≈ 3.464
Step-by-step explanation:
The side marked x is opposite the given 30° angle. The side marked 6 is adjacent to that angle. The trig function relating opposite and adjacent sides of a right triangle is ...
Tan = Opposite/Adjacent
Filling in values, we have ...
tan(30°) = x/6
Multiplying by 6 gives ...
x = 6tan(30°) = 6(√3/3)
x = 2√3 ≈ 3.464
