Answer:
total pages = 20
Step-by-step explanation:
60% of an unknown number is 12
Let the unknown number (total pages) be x.
60/100 of x = 12
60/100 * x = 12
3/5 x = 12
x = 12 * 5/3
x = 20
Answer:
38 quarters
Step-by-step explanation:
0.25 x 63 = 15.75
0.05 x 63 = 3.15
----------------------------
0.25 x 50 = 12.50
+ = $13.15
0.05 x 13 = 0.65
----------------------------
0.25 x 25 = 6.25
+ = $8.15
0.05 x 38 = 1.90
----------------------------
0.25 x 30 = 7.50
+ = $9.15
0.05 x 33 = 1.65
--------------------------
0.25 x 35 = 8.75
+ = $10.15
0.05 x 28 = 1.40
-------------------------
0.25 x 38 = 9.50
+ = $10.75
0.05 x 25 = 1.25
------------------------------
I hope this helps!
Answer:
the least common denominator would have to be 77
Step-by-step explanation:
because the product of 11 and 7 equals 77 but there is nothing less than that that can actually be a COMMON denominator
for example: 7 can be multiplied by numbers to get these out comes //
7,14,21,28,35,42,49,56,63,70,77 and 77 is the only one that 11 can actually equal to that is common with 7
Answer:
Volume = 18 cm^3
Surface Area = 58 cm^2
Step-by-step explanation:
Find the volume with the formula V=w*h*l
W= width
H = height
L = length
W= 2cm
H= 1 cm
L= 9 cm
V= w*h*l
V= 2cm * 1 cm * 9cm
V= 18 cm^3
Find the surface area with the formula A= 2(w*l + h*l + h* w)
W= width
H = height
L = length
W= 2cm
H= 1 cm
L= 9 cm
A= 2(w*l + h*l + h* w)
A= 2(2cm*9cm + 1cm*9cm + 1cm* 2cm)
A= 2(29cm)
A= 58cm^2
