Answer:
22.5 inches
Step-by-step explanation:
To find the unit rate, you divide the amount the plant grew by the amount of weeks. We learned that the plant grew 75 inches in 100 weeks, so we divide 75/100, to get 0.75. This means that the plant grows 0.75 inches per week, so in 30 weeks, it would grow 22.5 inches. This is calculated by multiplying 0.75 by 30 weeks.
Answer:
288 cubic feet
Step-by-step explanation:
add the 3 blocks.
block 1: 12*6*2=12*12=144
block 2: (12-4)*2*6=8*2*6=8*12=96
block 3: (12-4-4)*6*2=4*12=48
add them up:
144+96+48
288 cubic feet
with help of calculator
First, you multiply 2/5 by -5 to get -2. Then, you multiply -2 by -2/3 (-4/6's simplified form) to get 1 1/3 as your answer.
Yes because it shows that y is proprtional equal to 99 times x. so whenever you need to work out y, you get x and times it by 99.
