Answer:
Step-by-step explanation:
The question contains typos as I believe the boxes should be 5x4.2x3.2 in dimensions instead.
Assuming that and all 6 faces of each storage boxes will be painted, the surface area of each box is:
= (5*4.2*2) + (4.2*3.2*2) + (3.2*5*2)
= 100.88 square feet
4 boxes will have a total surface area of
100.88*4
= 403.52 square feet
Each pint of paint covers 50 square feet so a total of
403.52/50 = 8.07 or
9 pints is needed.

How long does it take for a 15 by 15 ft pond to evaporate
Answer:
Evaporation is when liquid turns into a gas or vapor.
This process happens to almost any body of water under the right conditions, including swimming pools.
This means, as a pool owner, you lose a measurable amount of pool water every day through evaporation. Several thousands of gallons of water per year for an average residential pool, in fact.

There is a population of 56,950 bacteria in a colony. If the number of bacteria doubles every 370 hours, what will the population be 1,850 hours from now?
Answer:
370×1850= 6,84,500
and then
56,950+6,84,500=7,41,450
the population will be 7,41,450
The population of bacteria after 1850 hrs in a colony, if the number of bacteria doubles every 370 hours, is 1822400.
What is multiplication?Along with addition, subtraction, and division, multiplication is one of the four basic mathematical operations. In mathematics, multiply refers to the continuous addition of sets of the same size.
Given:
The population of bacteria, P = 56950,
If the number of bacteria doubles every 370 hours then in 1850 hrs = 1850 / 370 = 5,
So, the no doubles 5 times in 1850 hrs,
Now if it doubles 1 time it will be 56950 × 2, and
for 5 times double population will be = 56950 × 2 × 2 × 2 ×2 × 2
P = 1822400
Therefore, the population of bacteria after 1850 hrs in a colony, if the number of bacteria doubles every 370 hours, is 1822400.

Answer:
Step-by-step explanation:
If 70% passed both, then that means 30% passed either one test, or neither test.
Since 80% passed the first test, we know that 20% of the students failed the first test.
This means that the other 10% of the students came from the 80% that already passed the first test.
These make up 10/80 = 12.5% of the people that passed the first test, meaning your answer is 100-12.5=87.5%

Step-by-step explanation: Is (5, 5) a solution to the equation y=x ?
Answer:
Yes, (5,5) is a solution of y=x
Step-by-step explanation:
A point is given as a coordinate pair, (x,y). The first number is x and the second number is y. A solution is a pair of numbers that will make the equation true.
To check if the point is a solution, fill in the first number in place of x in the equation. Then fill in the second number for the y.
Here we have the equation:
y = x
Substituting (filling in) we get:
5 = 5 a true statement. So (5,5) IS a solution.
Alternatively, you could graph the equation and verify that the point is on the graph. see image.

given f(x) = -x^2+x, find f(-1)
Answer:
f(-1)=0
Step-by-step explanation:
[tex]f(x) = -x^2+x\\\\Now,\\\\f(-1)=-(1)^{2} +(-1)\\\\f(-1)=1-1\\\\f(-1)=0[/tex]
Answer:
-2
Step-by-step explanation:
Since they said f(-1) we know that x = -1
So we plug in -1 for anything that says x
-1^2 - 1
Now we do 1^2 = 1 then mulitpy by -1
that give us -1
-1^2 = -1
-1 - 1 = -2

Maya started to run on a treadmill after setting its timer for 57 minutes. The display says that she has finished 27% of her run. How many minutes have gone by? Round your answer to the nearest tenth.
Answer:
15.4 minutes :)
Step-by-step explanation:
We need to turn the percentage into a decimal first :)
27/100 = 0.27
Now we multiply it by 57 to see how much time has gone by!! :)
0.27 x 57 = 15.39

Step-by-step explanation:
The equation h = 7 sine (startfraction pi over 21 endfraction t) 28 can be used to model the height, h, in feet of the end of one blade of a windmill turning on an axis above the ground as a function of time, t, in seconds. how long is the blade? assume that the blade is pointing to the right, parallel to the ground, at t = 0, and that the windmill turns counterclockwise at a constant rate. 7 feet 14 feet 21 feet 28 feet
The length of the blade of the windmill will be equal to 7 feet.
What will be the length of the windmill?
We have the equation
[tex]\rm h=7 \ Sin(\dfrac{\pi}{21t})+28[/tex]
At the time 't' = 0, the end of the blade is pointing to the right parallel to the ground meaning it is at the same height as the other end. (Ф = 0°)
So, by calculating the maximum height of this end at Ф = 90°. we can calculate the length of the blade.
Now, we know that a general model equation of a circular simple harmonic motion is represented as
[tex]\rm y=A\ Sinwt+k[/tex]
Where A is the amplitude that is, maximum displacement from mean to maximum position.
ω is the angular frequency.
Comparing the above equations we can conclude that
A = 7
so the difference in blade's end height at Ф = 0° and Ф = 90° is 7 feet.

Step-by-step explanation:
Let f(x)= x(2x-3)/(x+2)x. Find the domain, vertical and horizontal asymptote
Step-by-step explanation:
Domain of a rational function is everywhere except where we set vertical asymptotes. or removable discontinues
Here, we have
[tex] \frac{x(2x - 3)}{(x + 2)x} [/tex]
First, notice we have x in both the numerator and denomiator so we have a removable discounties at x.
Since, we don't want x to be 0,
We have a removable discontinuity at x=0
Now, we have
[tex] \frac{2x - 3}{x + 2} [/tex]
We don't want the denomiator be zero because we can't divide by zero.
so
[tex]x + 2 = 0[/tex]
[tex]x = - 2[/tex]
So our domain is
All Real Numbers except-2 and 0.
The vertical asymptors is x=-2.
To find the horinzontal asymptote, notice how the numerator and denomator have the same degree. So this mean we will have a horinzontal asymptoe of
The leading coeffixent of the numerator/ the leading coefficent of the denomiator.
So that becomes
[tex] \frac{2}{1} = 2[/tex]
So we have a horinzontal asymptofe of 2
A soccer stadium had a capacity of 25000 seats, but with the new area built this increased by 20%.
Calculate the number of people in the stadium if on a match only 65% of the seats are occupied.
Answer:
19,500 people
Step-by-step explanation:
20% of 25,000 is 5,000.
Add 5,000 to 25,000 - this will give you 30,000. That is a 20% increase.
65% of 30,000 is 19,500, thus there are 19,500 people in the stadium.
