The length is 18
12+12=24
60-24=36
36/2=18
therefore the length is 18
4 students still need to finish their science project because if you do
20 x 0.80=16
20-16=4
Answer:
$22.88
Step-by-step explanation:
The total bill is the subtotal plus tax. The tax is computed by multiplying the tax rate by the subtotal, which is the total of all items being billed.
subtotal = $5.25 +12.75 +2.99 = 20.99
tax = $20.99 × 0.09 = $1.89
The total bill is ...
subtotal + tax = $20.99 +1.89 = $22.88
Answer:
C. The total surface area is multiplied by 16. The volume is multiplied by 64.
Step-by-step explanation:
The volume of a rectangular prism is V = Base area × Height
Volume = Length × Breadth × Height
Surface area of a prism = A=2(wl+hl+hw)
l is the length
w is the width
h is the height
If all the dimensions are multiplied by 4;
Volume = 4L×4W×4H
New Volume = 64LWH
View volume = 64× Original volume.
New Surface area =2(16WL + 16HL +16HW)
New surface area = 2(16){WL+HL+HW}
New surface are = 16×2(WL+HL+HW)
New surface area = 16×original surface area.
The right answer is therefore;
The total surface area is multiplied by 16. The volume is multiplied by 64.
