C. 3 times 1/3 = 1 Its inverse property so that’s why it the answer
Answer:
4/5 frames/h
Step-by-step explanation:
Find the ratio frames per hour by dividing frames by hours:
(4 frames)/(5 hours) = (4/5) frames/hour
Answer:
-138/7
Step-by-step explanation:
use l.c.m . Or multiply through by 30.
Suppose the length of the card board was x cm by x cm
After squares of 4cm was cut from the corner, the dimension for the box will be:
length=(x-8) cm
width=(x-8) cm
height=4 cm
thus the volume will be:
V=length*width*height
V=4×(x-8)×(x-8)=144
x²-16x+64=36
this can be simplified to form a quadratic equation given by:
x²-16x+28=0
solving the quadratic equation we get:
x=2 or x=14
Thus we conclude that the original dimensions was:
length=14 cm ; width=14 cm
