Answer:
20 hrs
Step-by-step explanation:
20 hours: The volume of the pool is (length) × (width) × (height), or 30×10×2=600 cubic meters. Use a standard work equation, RT= W, where W represents the total work of 600 m
3
.
0.5×t=600
t=1200 minutes
Convert this time to hours by dividing by 60: 1200÷60=20 hours.
Alternatively, you could convert first:
hr
0.5m
3
×60min=
hr
30m

Next, use the standard work equation:
30 t = 600
t = 20 hours
The perimeter of the rectangular pool would be 90 meters and the length of the pool is 20 meters.
What is the perimeter of the rectangle?The perimeter of a rectangle is defined as the addition of the lengths of the rectangle's four sides.
The perimeter of a rectangle = 2(L+W)
Where W is the width of the rectangle and L is the length of the rectangle
We have been given that the ratio of length to width of a rectangular swimming pool is 4 : 5.
Let the length of rectangular swimming pool would be 4x
And the width of rectangular swimming pool would be 5x
Since the width of the swimming pool is 25 meters.
So 5x = 25 ⇒ x = 25/5 = 5
So the length rectangular swimming pool would be 4(5) = 20 meters.
The perimeter of the pool = 2 [ length + width ]
The perimeter of the pool = 2 [ 20 + 25]
The perimeter of the pool = 2 (45)
The perimeter of the pool = 90 meters

Karen bought cupcakes for her sister's birthday party. 3 cupcakes had sprinkles on top. The other 27 cupcakes did not have sprinkles. What percentage of the cupcakes had sprinkles?
Answer:
10%
Step-by-step explanation:
so
3 cupcakes had sprinkles
27 didn't have sprinkles
which means that there are a total of 30 cupcakes, (because 3 + 27 is 30)
so then set up a proportion
part/whole = percent/one hundred
substitute in the given values
3 / 30= precent/100
simplify
1/10 = precent/100
you don't have to use cross products here because it is pretty obvious that 10 * 10 = 100 so then just multiply 1/10 by 10 and you get your answer
percent = 10

Marcus is trying to lose weight for next football season, Four weeks into his diet, he weighed 232
pounds. At nine weeks, he weighed 224.5 pounds. How many weeks will it take Marcus to reach his
goal weight of 214 pounds?

18/1.5 = 12 weeks
The science club and the French club both ordered pizzas for their end-of-year banquets. After the banquets, the science club had 1 1/4 pizzas leftover and the French club had 2 5/24 pizzas leftover. Between the two clubs, how many total pizzas were leftover?
A. 23/24
B. 1 1/4
C. 3 1/4
D. 3 11/24
Answer:
[tex]3\frac{11}{24}[/tex]
Step-by-step explanation:
Given parameters:
Leftover pizza from the Science club = [tex]1\frac{1}{4}[/tex]
Left over pizza from french club = [tex]2\frac{5}{24}[/tex]
Unknown;
Total left over pizzas between the two clubs = ?
Now to solve problem, simply add the leftover from the science club and the french club together;
Total left over pizza = [tex]1\frac{1}{4}[/tex] + [tex]2\frac{5}{24}[/tex]
= [tex]\frac{5}{4} + \frac{53}{24}[/tex]
= [tex]\frac{83}{24}[/tex]
= [tex]3\frac{11}{24}[/tex]
The total left over pizza between the two clubs is [tex]3\frac{11}{24}[/tex]

Help Simplify 6(x + 4).
Answer:
6x+24
Step-by-step explanation:
The simplified form of the expression 6(x + 4) is 6x + 24.
We have,
To simplify the expression 6(x + 4), we can apply the distributive property of multiplication over addition.
The distributive property states that when we have a number multiplied by a sum of terms, we can distribute the multiplication to each term separately and then simplify.
In this case, we have 6 multiplied by the sum (x + 4). Applying the distributive property, we can multiply 6 by both x and 4:
6(x + 4) = 6 * x + 6 * 4
Simplifying further:
6x + 24
Therefore,
The simplified form of the expression 6(x + 4) is 6x + 24.

1.The growth of a sample of bacteria can be modeled by the function b(t)=100(1.06)t where b is the number of bacteria and t is time in hours.
What is the number of total bacteria after 3 hours?
Given:
The growth of a sample of bacteria can be modeled by the function
[tex]b(t)=100(1.06)^t[/tex]
where, b is the number of bacteria and t is time in hours.
To find:
The number of total bacteria after 3 hours.
Solution:
We have,
[tex]b(t)=100(1.06)^t[/tex]
Here, b(t) number of total bacteria after t hours.
Substitute t=3 in the given function, to find the number of total bacteria after 3 hours.

Parallel to y=-3x+4, x-intercept at 4
Answer:
y = -3x + 12
Step-by-step explanation:
The slope of parallel line is the same as the original line.
If the x-intercept is 4, this as a point can be stated as (4, 0)
We can now solve for the y-intercept.
y = -3x + b
0 = -3(4) + b
0 = -12 + b
12 = b
Put everything we solved for back into the formula [ y = mx + b ]
y = -3x + 12
