ANSWER
307½ gallons of water
EXPLANATION
The volume of the rectangular swimming pool is
where l=25ft and w=20½ ft.
when it is filled to a depth of 4½ ft ,then the height is , h=4½ ft.
We substitute these values into the formula to get:
If one cubic foot of water is 7½ gallons, then 2306.25 cubic feet will be
We need 307.5 gallons of water to fill the pool.
Answer:
They will take 6 minutes to do the job together.
Slowest person do 2/5 of the total work.
Step-by-step explanation:
Given,
Time taken by first person = 10 minutes,
⇒ One day work of the first person = ,
While, time taken by second person = 15 minutes,
⇒ One day work of second person = ,
So, when both persons work together, total one day work = ,
Thus, the total time taken by the both persons when they work together,
x = = 6 minutes
The one who takes more time is slower.
Now, the part of the work done by the slowest person ( second one),
Answer:
The percentage increase in A is 44%. The percentage increase in V is 72.8%.
Step-by-step explanation:
The easiest way to go about solving this problem is to pick your own numbers and plug them into the given equations.
For example, let's say that k = 5 and that r = 10.
⇒
⇒
The question is asking, what is the percentage increase if r is increased by 20%. Our chosen k-value will stay the same but our r-value is going to increase. To find the new value of r, we multiply 10, our current value of r, by 1.2. This gives us a new value for r, which is 12.
Now, we are going to plug in our new r-value and our k-value into the given equations. k = 5; new r = 12
⇒
⇒
Next, we have to calculate the percentage increase in our values of A and V. To do this, we use the following formula:
Percentage Increase for A
Initial value: 500
Final Value: 720
Percentage Increase for V
Initial value: 5000
Final Value: 8640
The percentage increase for A is 44% and the percentage increase for V is 72.8%.
Hope this helps!
b. 3x - 4 = 5x - 10
c. 3x + 4 = 5x + 10
d. 3x - 4 = 5x + 10
Answer:
number rounded to the nearest thousand is 276,000
Step-by-step explanation:
A museum had 275,608 visitors last year.
We round the given number to nearest thousand
275,608
8 is in once place
0 is in tens place
6 is in hundreds place
5 is in thousands place
7 is in ten thousands place
2 is in hundred thousands place
Here 5 is in thousand place, 6 is in hundreds place that is greater than 5
so we add 1 with 5. put 0 for remaining places
276,000
