Answer:
Part A: 4 cups
Part B: 5 fluid ounces
Step-by-step explanation:
Part A: Since the ratio of vinegar to water is 1:16, 1 cup of vinegar is 16 cups of water. Divide both by 4 to get 1/4 cups of vinegar to 4 cups of water.
PartB: Since we have 80 fluid ounces of water, and 16 is 16 times 1, 80/16 is 5 fluid ounces.
Answer:
a negative times a negative is a positive so 8×3=24/19 will give you that answer
you add -2 to the other side with 25 and get 27 then u work the rest of the problem out to solve for x
Answer:
106
Step-by-step explanation:
Given that:
Mean (m) = 13.5 pounds
Error margin = 0.025
α = 99%
Variation interval = range = 13.3 to 13.7
Standard deviation (σ) estimate from range :
Range / 4
(13.7 - 13.3) /4
= 0.4 / 4
= 0.1
Zcritical at 99% = 2.576
Using the formula :
Sample size (n) = [ (Zcritical * σ) / M. E]^2
n = [(2.576 * 0.1) / 0.025]^2
n = (0.2576 / 0.025)
n = 10.304^2
n = 106.172
n = 107 samples
Answer:
8
Step-by-step explanation:
hypotenuse^2= leg^2 + leg^2
10^2= 6^2 + x^2
100= 36 + x^2
100-36= x^2
64= x^2
√64=√x^2
8= x
Astronomers deal with objects in space, so it's most likely they would use geometry to determine how far they are, how big they are, etc.
Have a nice day! :)
