Answer:
18 nickels
Step-by-step explanation:
4 pennies = $0.04. 22 coins minus the 4 pennies = 18. So, 18 nickels is equal to $0.90. Because she has at most 22 coins and they're worth at least $0.78 then $0.94 would make since.
Nice and simple. PEMDAS. Parentheses, exponents, multiple, division, addiction, subtraction.
The first thing you do is solve the numbers in the parenthesis, which would turn to
(312) + (714) = 1026
Answer:
1. 24 quarts. 2. 85 seconds.
Step-by-step explanation:
1. We need to know how many 2/3 are in 4.
if 3/3 are in 1 cup, then 12/3 are in 4 cups.
there are 6 twos in 12, so there are 6*2/3 cups in 4 cups.
Each 2/3 needs 4 quarts of green, and we have six times that.
6*4 = 24, so we need 24 quarts of green paint.
2. The 12.75 miles would go in the "d" or distance part of the equation.
d = 0.15t
12.75 = 0.15t (divide both sides by 0.15)
12.75/0.15 = 0.15t/0.15
t = 85, so 85 seconds.
12.75 miles isn't the distance between the two cities, it's much farther, so this answer makes sense.
<h2>circumference = 87.92ft</h2>
Step-by-step explanation:
radius (r) = 14ft
circumference = 2π×r
= 2 × 3.12 × 14
= 87.92ft
