A water tank in the shape of a cylinder contains 54,000 gallons of water. 60% filled If the tank is only 60% filled, how many gallons of water can the tank hold? Enter the correct answer in the box.
Answer:
90000 gallons
Step-by-step explanation:
Given
[tex]Capacity\ at\ 60\% = 540000[/tex]
Required
Determine the full capacity
Let the maximum number of gallons be m.
So, we have:
[tex]60\% * m = 54000[/tex]
Convert % to decimal
[tex]0.60 * m = 54000[/tex]
Divide both sides by 0.60
[tex]m = \frac{54000}{0.60}[/tex]
[tex]m = 90000[/tex]
Hence, the maximum number of gallons it can hold is 90000 gallons
Answer:
Step-by-step explanation: capacity is 60% = 54000
Determine what is missing = 90000
a 4kg ham cost $13/kg. Find the cost per pound . Round to the nearest hundred
Answer:
The cost per pound of the ham is $5.89.
Step-by-step explanation:
Given that a 4kg ham cost $13/kg, in order to find the cost per pound the following calculation has to be made:
1 kg = 2.20462 pounds
2.20462 = 13
1 = X
((1 x 13) / 2.20462) = X
13 / 2.20462 = X
5.89 = X
Therefore, the cost per pound of the ham is $5.89.

Tasha is packing gift bags that include
the same items. She has 72 glow sticks,
36 markers, and 24 bottles of bubbles.
Tasha believes that she can pack no
more than 6 bags using all of her
supplies. Do you agree with Tasha? Explain.
Answer:
No, I do not.
She can pack up to 12 bags
Step-by-step explanation:
Given
[tex]Glow\ sticks = 72[/tex]
[tex]Markers = 36[/tex]
[tex]Bubbles = 24[/tex]
Required
Is Tasha correct?
The maximum number of bags she can pack is determined by the greatest common factors (GCF) of the items.
i.e. GCF of 72, 36 and 24.
This is calculated as:
[tex]24 = 2*2*2*3[/tex]
[tex]36 = 2 * 2 *3*3[/tex]
[tex]72 = 2 * 2 * 2 *3*3[/tex]
Multiply all common factors:
[tex]GCF = 2 * 2 * 3[/tex]
[tex]GCF = 12[/tex]
The GCF is 12.
This implies that she can pack up to 12 bags
Suppose a - b = 0Which one of these expressions equals ab?
A. 2a
B. 0
C. b^2

E. a/b
If a-b=0, a=b, so ab=bb=b^2
Answer:
b^2
Step-by-step explanation:
a - b = 0
Add b to each side
a-b+b = 0+b
a=b
We want to find ab
Replace a with b

What is the sum of the interior
angle measures of a polygon
that has 7 sides?
Sum = [?]
Hint: Sum = (n-2)180
Answer:
Sum = 900 degrees.
Step-by-step explanation:
Sum = (n-2)180
=(7-2)180
=(5)180
=900
Answer:
900 degrees
Step-by-step explanation:
The formula for calculating the sum of the interior angles of a regular polygon is : ( n - 2) × 180°. when n is number of sides.
Sum of angles = ( n-2) × 180
Sum of angles = (7-2) × 180
Sum of angles = 5 × 180
Sum of angles = 900 degrees
The price of a shirt has been discounted by $20. The sale price is $24.95. What percent of the original list price is the discount?
(a) Use the verbal description to write a verbal model.
o change in price = (original price)/(percent)
o change in price = (percent)(original price)
O change in price = (percent) - (original price)
o change in price = (original price) + (percent)
O change in price = (percent)/(original price)
(b) Assign labels to the quantities in the verbal model.
--Select-
= 20
---Select-
---Select-
= 44.95
(C) Use the labels to write a mathematical model.
(d) Solve the problem. (Round your answer to the nearest whole number.)
%
Answer:
this is an example
Step-by-step explanation:
There are a few different ways to approach this problem, including the following two methods.
1) Find 20% of the original price, then subtract that amount from the original price.
To find a percentage of a number, you multiply the number by the percentage. (You are finding a part of a whole.)
20% = 20/100 = 1/5 or 20% = 0.20
Original Price: $24 Find 20% of $24. (Note: "of" is taking part of a whole, so you multiply.)
0.20 x 24 = 4.80 This is the mark down, or the amount you subtract from original price.
Sale Price = Original Price - Mark Down
= 24.00 - 4.80
= 19.20
2) If you save 20%, you are still paying 80%. (100-20 = 80) Therefore the sale price is 80% of the original price.
80% = 80/100 = 4/5 or 80% = 0.80
Sale Price = 80% of Original Price
= 0.80 x 24
= 19.20

In the diagram, ∠XWY congruent to ∠ZWY. Find XY.
Answer:
10
Step-by-step explanation:
Let XY = a
Since,
XY + YZ = XZ
a + YZ = 24
YZ = 24 - a
By angle bisector property:
[tex]\frac{WX}{WZ} = \frac{XY}{YZ} \\ \\ \frac{15}{21} = \frac{a}{24 - a} \\ \\ \frac{5}{7} = \frac{a}{24 - a} \\ \\ 5(24 - a) = 7a \\ \\ 120 - 5a = 7a \\ \\ 120 = 7a + 5a \\ \\ 120 = 12a \\ \\ a = \frac{120}{12} \\ \\ a = 10 \\ \\ \implies \: XY = 10[/tex]
