Answer:
9
Step-by-step explanation:
Each pen can only hold 8 pigs, and pens cannot be split up into fractions.
Divide. 71 / 8 = 8.875
There is no 7/8 of a pen, so you must round up.
8.875 → 9.
7.
irt = simple Interest we can fill in what we know so $500 * I * 20 = $250 than we solve for I so $250 / 500 = 0.5 than 0.5 / 20 = 0.025
8. Irt = simple interest fill it in 850 * I * 10 = $255 and then solve for I 255 / 850 = 0.3 than 0.3 / 10 = 0.03
9. Irt = simple interest 1200 * I * 15 = $720 and than solve for I so 720 / 1200 = 0.6 and then 0.6 / 15 = 0.04
Assuming that you mean 7500 a year, Alex would have to pay 30,000 over the course of 4 years. His scholarship will bring that total down to 29,750. If he has four years to save, each year he should be saving $7,437.50. (29,750/4). For each month, he should be saving a total of $619.79 (7,437.50/12)
Answer: 12
40% = 40/100 = 0.40
"of" means "multiply" in percent word problems like this. Multiply 0.40 with 30 to get 0.40*30 = 12
Optionally, you can solve the equation below for x
part/whole = percent/100
x/30 = 40/100
x/30 = 0.40
x = 0.40*30
x = 12
much of those steps follow a similar pattern to what was mentioned earlier.
Answer:
a =5.3
Step-by-step explanation:
The Pythagorean theorem is
a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse
a^2 + 6^2 = 8^2
a^2 +36 = 64
Subtract 36 from each side
a^2 +36-36 = 64-36
a^2 =28
Take the square root of each side
sqrt(a^2) = sqrt(28)
a = 5.291502622
To the nearest tenth
a =5.3
