Answer:
the height of the water in the pool is 2m
Step-by-step explanation:
This problem bothers on the mensuration of solids.
Given data
Volume of pool v= 270m³
Base length l= 15m
Base width b= 9m
Height h=?
The pool takes the shape of a rectangular prism
The expression for the volume of the pool is
v= l*b*h
Substituting our given data we have
270= 15*9*h
270= 135h
h= 270/135
h= 2
Therefore the height h =2m
Answer:
$43.20
Step-by-step explanation:
A swimsuit that originally cost $90 before any discount is on sale for 20% off.
X = price of swimsuit
X = 90
20% off = 90 * 0.8 = 72
The swimsuit is then put on clearance for an additional 40 % off the sale price.
72 * 0.6 = 43.2
what is the final price?
$43.20
Answer:
Play 3
Step-by-step explanation:
Given:
Required [Missing from the question]:
Determine the play with the least change in yard?
To do this, we ignore the sign in front of each yard before we analyze.
So, we have:
Play 1 has a change of 4
Play 2 has 6
Play 3 has 2
Play 4 has 3
<em>From the above analysis, play has the least (which is 2)</em>
Given that the tornado traveled 260 miles in 4 hours, its initial speed is 65 mi/h. Then, slowing by 20% every hour, the speed after 2 hours can be calculated through the equation,
speed = (65 mi/h) x (1-0.2)^2
speed = 41.6 mi/h
Thus, the speed of the tornado after 2 hours is approximately 41.6 mi/h.
