Answer:
a) 40 pints b) 64 ounces c) 46.5 quarts d) 52 cups e) 23 tablespoons f) 7 gallons g) 108 teaspoons h) 384 fluid ounces
Step-by-step explanation:
<u>a. 5 gallons to pints</u>
1 pint = 0.125 gallons
x pint = 5 gallons
<em>Cross multiply</em>
0.125x = 5
x = 40 pints
<u>b. 128 tablespoons to fluid ounces</u>
1 ounce = 2 tablespoon
x ounce = 128 tablespoons
<em>Cross multiply</em>
2x = 128
x = 64 ounces
<u>c. 93 pints to quarts</u>
1 quart = 2 pint
x quart = 93 pints
<em>Cross multiply</em>
2x = 93
x = 46.5 quarts
<u>d. 13 quarts to cups</u>
1 cup = 0.25 quart
x cup = 13 quarts
<em>Cross multiply</em>
0.25x = 13
x = 52 cups
<u>e. 69 teaspoons to tablespoons</u>
1 tablespoon = 3 teaspoons
x tablespoons = 69 teaspoons
<em>Cross multiply</em>
3x = 69
x = 23 tablespoons
<u>f. 112 cups to gallons</u>
1 cup = 0.0625 gallons
112 cups = x gallons
<em>Cross multiply</em>
x = 112 x 0.0625
x = 7 gallons
<u>g. 18 fluid ounces to teaspoons</u>
1 teaspoon = 0.166667 ounces
x teaspoon = 18 fluid ounces
<em>Cross multiply</em>
0.166667x = 18
x = 108 teaspoons
<u>h. 3 gallons to fluid ounces</u>
1 gallon = 128 fluid ounces
3 gallons = x fluid ounces
<em>Cross multiply</em>
x = 128 x 3
x = 384 fluid ounces

You could set up a proportion
86/x = 98/100
Then solve for x, I'll do it by cross-multiplying.
86 times 100 divided by 98 = 87.755102
87-88 problems
the recipocal is 0.17857142857
This year there are 900 rabbits which represents 200% of last year's population, means that last year the number of rabbits was:
x = 900 (100/200) = 450 rabbits.
The mathematical expression can be derived by a simple rule of three.
So, for last year the population was 450 rabbits.
Answer:
3.2
Step-by-step explanation:
I'm not totally sure what you mean. I'm reading it as y² = 5x
So let y = 4
4² = 5x
16 = 5x Divide by 5
16/5 = x
3.2 = x
