Length of the aquarium is 35 yd
Step-by-step explanation:
- Step 1: Volume of the aquarium = 210 yd³ given by Volume = length × width × height. Width = 3 yd and Height = 2 yd
Length = Volume/Width × Height
= 210/3 × 2 = 210/6
= 35 yd
Answer:
Step-by-step explanation:
1) Price of 8 pack of toothbrushes = $ 18.12
Price he paid after using coupon = 18.12 - 3 = $ 15.12
Unit rate = Price he paid ÷ number of toothbrushes
= 15.12 ÷ 8
= $ 1.89
2) 0.5 hours = 30 minutes
Duration of guitar class on Monday = 30 minutes
Duration of guitar class on Tuesday = 1.5 hours = 1 hr 30 min
Duration of guitar class on Thursday = 2 hrs
Total duration = 30 min + 1hr 30 min + 2 hrs
= 4 hrs
Amount paid for 4 hrs = $ 180
Rate per hour = 180 ÷ 4
= $ 45
Answer:
Choice A: x^2−2x+4− 15/x+2
Step-by-step explanation:
Answer:
A = 5x^2 + 10x
Step-by-step explanation:
A = H*W
H = 5x
W = x + 2
A = 5x(x + 2)
Distribute
5x*x = 5x^2
5x*2 = 10x
A = 5x^2 + 10x
A + 4 = s
2(a+2) = (s+2)
plug in the upper equation into the lower equation
2(a+2) = (a+4+2)
2a+4 = a+6
a+4 = 6
a = 2 years old
