The radius of container is 2.6 inch.
What is volume?The amount of space occupied by a three dimensional figure as measured in cubic units.
Formula for the volume of cylinder[tex]volume of cylinder= \pi r^{2} h[/tex]
where,
r is the radius
h is the height
According to the given question
shape of the container is cylindrical.
Height of the container, h = 12 inches
Volume of container = 258.75 cubic inches
for the radius of the container
volume of container = [tex]\pi r^{2}h[/tex]
258.75 = 3.14×[tex]r^{2}[/tex]×12
258.75 =37.68×[tex]r^{2}[/tex]
[tex]\frac{258.75}{37.68} =r^{2}[/tex]
[tex]6.9=r^{2}[/tex]
⇒ [tex]r = \sqrt{6.9} =2.62inch[/tex] = 2.6 inch
Hence, the radius of container is 2.6 inch.

Marisol is being paid $792 to provide nutrition counseling, It took her 8 hours more than she expected, so
she earned $4 per hour less than she originally calculated. How long had she anticipated it would take to do
the job?
Answer: 44 hours.
Step-by-step explanation:
Marisol is being paid $792.
We know that the job took her 8 hours more than she expected, so if we define T as the time she expected, this job took her:
T + 8 hours.
The amount of money per hour that she expected is calculated as:
$792/T = X
And for those 8 extra hours, she won $4 less per hour, then we have:
$792/(T + 8hs) = X - $4
Then we have a system of equations:
$792/T = X
$792/(T + 8hs) = X - $4
To solve this, we can notice that in the first equation X is isolated, then we could replace that in the second equation to get:
$792/(T + 8hs) = $792/T - $4
Now we can solve this for T.
$792 = ($792/T - $4)*(T + 8hs) = $792 + $792*(8hs/T) - $4*T + $32*hs
0 = $792*(8hs/T) - $4*T + $32*hs
Let´s multiply this both sides by T
0*T = ($792*(8hs/T) - $4*T + $32*hs)*T
0 = $792*8hs - $4*T^2 +$32*T*hs
This is a quadratic equation, where i will write this witout units so it is easier to read and follow:
0 = -4*T^2 + 32*T + 792*8
The solutions cab be found by using the Bhaskara´s formula, these are:
[tex]T = \frac{-32 +- \sqrt[2]{(32^2 - 4*(-4)*(792*8)} }{2*-4} = \frac{-32 +-320}{-8}[/tex]
Then the solutions are:
T = (-32 + 320)/-8 = -36 hours (This is a negative time, and it does not really have a meaning in this problem, so we can discard this option)
The other solution is:
T = (-32 - 320)/-8 = 44 hours.
Then we can conclude that she expected the job would take 44 hours in total.

A recipe calls for 2/3 cups of sugar per batch. Elena used 5 1/3 cups of sugar to make multiple batches of cookies. How many batches did she make?
Answer:
8
Step-by-step explanation:
In order you find the answer, you must divide 5 1/3 by 2/3.
In order to do this, you have to convert 5 1/3 into an irregular fraction, by multiplying 5 by 3 and adding it to 1. You'll end up with 16/3
When dividing fractions, you multiply the first number by the reciprocal of the second. 16/3 is the number being divided, so 2/3 will be our second number. The reciprocal of 2/3 is 3/2.
16/3 x 3/2 = 8.

Perhaps, x = 9 ?
Step-by-step explanation:
The value 9 is 200% of what number?
Answer:
18
Step-by-step explanation:
If 100% is 9 then you need to multiply by 2 to get 200% which is 18.
Answer:
4.5
Step-by-step explanation:
To get from 200% to 100%, you have to divide by 2, so then do the same thing to 9.
9 divided by 2 is 4.5
Evaluate 2(5 + x^2)+ y if x = 3 and y = 2
Answer:
30
Step-by-step explanation:
Start by substituting
2(5+3²) +2 = ___
Parenthesis
3²= 3 · 3 = 9
add that to 5 = 14
2(14) +2 = ___
2 times 14 = 28.
28 + 2 = 30
Answer:
30.
Step-by-step explanation:
2(5+ x^2)+ y
x=3, y=2
Using the given information for x and y and distributing that into the equation, the equation becomes:
2(5+ 3^2)+ 2
Now, use order of operations or PEMDAS (parenthesis, exponents, multiplication, division, addition, subtraction) to solve the problem.
The answer you should get is 30. :,)
