Answer:
$2.75
Step-by-step explanation:
A quarter's value as placed on it by the U.S. Treasury Department is $0.25, or 1/4 of a dollar.
Henry had 15 quarters, in which he gives his sister 4: 15 - 4 = 11
Henry now has 11 quarters. Multiply 11 with 0.25: 11 x 0.25 = 2.75
Henry has $2.75

If there are 12 boys and 13 girls, there are 25 kids in the class total. This means that 13/25 are girls. In order to know the probability, you must divide 13 by 25, which gets an answer of 0.52, which is equal to 52%.

Answer:
w = 10
Step-by-step explanation:
Solve for w:
w/4 + 8.25 = 10.75
Put each term in w/4 + 8.25 over the common denominator 4: w/4 + 8.25 = w/4 + 33/4:
w/4 + 33/4 = 10.75
w/4 + 33/4 = (w + 33)/4:
(w + 33)/4 = 10.75
Multiply both sides of (w + 33)/4 = 10.75 by 4:
(4 (w + 33))/4 = 4×10.75
(4 (w + 33))/4 = 4/4×(w + 33) = w + 33:
w + 33 = 4×10.75
4×10.75 = 43:
w + 33 = 43
Subtract 33 from both sides:
w + (33 - 33) = 43 - 33
33 - 33 = 0:
w = 43 - 33
43 - 33 = 10:
Answer: w = 10
