The perimeter = 2 * (3*y - 5) + 2*2*y = 6*y - 10 + 4*y = 10y - 10
Answer:
20 - (3(7) - 4(4)) = 15
Step-by-step explanation:
Answer:
4 years
Step-by-step explanation:
I=prt
1440=4000(r)0.09
4000r * 0.09 = 1440
divide both sides by 4000 times 0.09
r = 4
Answer:
x=t/5
Step-by-step explanation:
5x=t
multiply both sides by 5 to make x the subject
x=t/5
Answer: Below
Step-by-step explanation:
Volume is based off of the formula (base × height/depth), with base being (width × length).
We know the three dimensions of the taller box, so:
7.75 × 2 × 12 = 186
The smaller box is 20% shorter. 12 × 0.8 gives us the 0% height, which is 9.6.
7.75 × 2 × 9.6 = 148.8
Since the problem is asking for the difference of the two volumes we do:
186 - 146.8 = 39.2
Our answer is 39.2
