The third answer
1 quarter, 6 dimes, 1 nickel, 7 pennies
Answer:
C -6
step by step explanation:
So lets say for example you have 4 remainder 2. To turn that into a decimal you have to divide the whole number by the remainder to make to fraction. So now you have 4 2/4 which is the same as 4 1/2. To turn the fraction into a decimal you do 100 divided by the denominator (2) which is 50, and then multiply by the top numerator (1). Now you add on the whole number (4) onto your other number/100 (50/100=0.5) to make 4.5.
Examples:
5 remainder 4:
4/5 = (100/5 x 4) 20 x 4 = 80
80/100=0.08
0.08 + 5= 5.08
If you have a denominator that goes into 10 easily (2, 4, 5, 10) then you just have to multiply the numerator (top number) by the same number as the bottom to make 10, and then just turn that into a decimal:
Example:
4 remainder 3:
3/4 x 2.5 = 7.5/10
=75/100 = 0.75
0.75 + 4 = 4.75
Answer: The value of q is exactly 7
------------------------------------
Explanation:
L = 16 is the length
W = 3 is the width
H = q is the unknown height
S = 362 is the surface area
We'll use the formula
S = 2*(L*W+W*H+L*H)
which is the surface area formula for any rectangular block
So plug in the given info and solve for q
S = 2*(L*W+W*H+L*H)
362 = 2*(16*3+3*q+16*q)
362 = 2*(48+3q+16q)
362 = 2*(48+19q)
362/2 = 2*(48+19q)/2 ... divide both sides by 2
181 = 48+19q
48+19q = 181
19q+48 = 181
19q+48-48 = 181-48 .... subtract 48 from both sides
19q = 133
19q/19 = 133/19 .... divide both sides by 19
q = 7
