Answer:
Step-by-step explanation:
area of rectangle=l*b
=8*15
=120 cm^2
area of rectangle=l*b
96=16*b
96/16=b
6=b
Answer:
volume from geometri always:
base area × h
if have peak point always:
1/3 × base area × h
the base of the pyramid in the figure is rectangle. then base from rect. is:
l × w
= 9 × 7
= 63
let get into formula: (use the second formula because pyramid has a peak point)
=1/3 × ba × h
=1/3 × 63 × 7
=21 × 7
=147 yd³
Answer:
8 hours
Step-by-step explanation:
Let's first find how many inches the candle would have burned in 1 hour.
6 in:12 hours
x: 1 hour
We can divide 12 by 12 to get 1. This means we need to divide 6 by 12 to get x
x=1/2 inches
1/2 inches:1 hour
4 inches: x hours
We divide 4 by 1/2 to get 8. 1/2*8=4. This means...
x=1 hour*8=8 hours
