Hello!
The aquarium that is 15 inches long, 18 inches deep, and 12 inches wide can hold exactly 3240 cm^3 of water.
To fine the volume of the tank, we must use this formula:
V = l × d × w
We know that all three aquariums are 18 in deep and 12 in wide, but we do not know the length.
We've been given three lengths (12 in, 15 in, and 18 in). Substitute and find out which one will give us a volume of 3,240 cm^3:
V = 12 × 18 × 12
V = 2,592
The first length won't work.
V = 12 × 18 × 15
V = 3,240
Area of a rectangle= lxw
1.7=3.4z
1.7/3.4= 0.5
z=0.5
Anything smaller than 0.75 would work, such as 0.25
Answer:
x = 0
Step-by-step explanation:
if 2y + x = 4
we can assume that y = 2
if y - 3x = 2
it means 2 - 0 = 2
therefore x = 0
Answer:
D. 1.08 hours
Step-by-step explanation:
Speed = distance / time
Going to the bike shop
speed = 6 mile/hour
Distance = 2.5 mi
Time = t
Speed = distance / time
6 = 2.5 / t
Cross product
6t = 2.5
Divide both sides by 6
t = 2.5/6
= 0.417 hour
She waited for 30 minutes for the repair, that is 0.5 hour
Going back home
Speed = 15 miles/hour
Distance = 2.5 mi
Time = t
Speed = distance / time
15 = 2.5 / t
Cross product
15t = 2.5
Divide both sides by 15
t = 2.5 / 15
= 0.167 hour
Total time of the entire trip =
0.417 hour + 0.5 hour + 0.167 hour
= 1.084 hour
Approximately 1.08 hour
The correct answer is D. 1.08 hours
