An above-ground swimming pool is 5 feet long, 4 feet wide, and 3 feet deep and is shaped like a rectangular prism. A rectangular prism has a length of 5 feet, height of 3 feet, and width of feet. If you use a net to find the amount of material used to make the pool, what faces are included in the calculation?
Answer:
the faces representing the sides and bottom of the pool are included
Step-by-step explanation:
Obviously, there is no pool material covering the top of the pool. Rather, it is "an open-top box", so the area of the faces of the box does not include the area of the top. The five faces other than the top face are included.

Batman, who is having a slow year for crime, has resorted to saving cats from very tall buildings. Our fearless 6 foot tall hero is 40 feet from the the Petsmart building the cat was trying to break in to, in order to get his paws on the pumpkin spice cat nip. Batman sights the top of the building at a 30° angle, how high is the building?
Answer:
29.094 feet tall
Step-by-step explanation:
tan(30) = [tex]\frac{x}{40}[/tex]
so tan is opposite over adjacent which means that we should be able to solve for the opposite as we have the angle (30) and the distance from Batman to to building, which is (40 feet), with these numbers you will do, tan(30) = [tex]\frac{x}{40}[/tex] and from that you will solve for x, and from x you add the 6 foot of batmans height
A cylindrical tank is half-full of oil. The cylinder has base radius of 100cm.The height of the cylinder is 250cm. 1 litre =1000cm cubed
How many litres of oil are in the tank? Round your answer to the nearest litre.
Answer:
Step-by-step explanation:
area of a cylinder=. V=πx r^2xh
so...
πx100^2x125=3926990.817 (the height is 125 because only half of it has oil)
3926990.817/1000=3927litres

What is the volume, in cubic cm, of a rectangular prism with a height of 19cm, a
width of 16cm, and a length of 8cm?
Answer: 2432
19 x 16 x 8 = 2432
Answer: 2,432 cm³
Step-by-step explanation: To find the volume of a rectangular prism or a prism whose base is a rectangle, we use the formula below.
Volume = length × width × height
Since the rectangular prism has a length of 8 centimeters, a width of 16 centimeters, and a height of 19 centimeters,
we can plug this information into the formula to get
(8 cm)(16 cm)(19 cm).
This gives us 2,432 cm³.
So the volume is 2,432 cm³.

The mean temperature for the first 7 days in January was 4 °C.
The temperature on the 8th day was 4 °C.
What is the mean temperature for the first 8 days in January?
Answer:
4 degrees Celsius
Step-by-step explanation:
Since the mean is (total/amount), we can remake this to get That mean*amount=total. For the first 7 days, 4*7=28 for our total, and add that to the 8th day to get 32 for our total. 32/8=4 for our mean for the first 8 days of january
Answer:
Answer:
4 degrees Celsius

How to solve #2 if you don’t know any of the side lengths?? (We’re learning about Pythagorean Theorem)
Answer:
Applying Pythagorean theorem in right triangle with c is longest side and a, b are the other sides:
=> c^2 = a^2 + b^2
=> a^2 = c^2 - b^2
=> b^2 = c^2 - a^2
Hope this helps!
:)
Answer:
c² = a² + b²
a² = c² - b²
b² = c² - a²

Sherri hikes on the Pacific Coast trail. She plans to hike 3.72 miles. If she hikes at an average speed of 1.2 miles per hour, how long will she hike?
Answer:
3.1 hours
Step-by-step explanation:
Average Speed=Distance Traveled ÷ Time Taken
Sherri plans to hike 3.72 miles at an average speed of 1.2 miles per hour.
Average Speed=1.2 miles per hour.Distance =3.72 milesTherefore:
1.2 miles per hour=3.72 miles ÷ Time
1.2 miles per hour X Time=3.72 miles
Time = 3.72 ÷ 1.2 hours
Time taken by Sherri=3.1 hours
Sherri will hike for 3.1 hours.
Find the value of x.
Answer:
x = 61
Step-by-step explanation:
x and 29 are complementary angles so they add to 90 degrees
x+29 = 90
Subtract 29 from each side
x+29-29 = 90-29
x = 61
Answer:
61 degrees = x
Step-by-step explanation:
Since angle measures x and 29 are complementary angles, subtract 29 from 90 degrees.
90 - 29 = 61 degrees is the value of x

Which statement is true? Question 10 options: A) |13| = – 13 B) – |13| = 13 C) |–13| = 13 D) – |–13| = 13
Answer:
The answer is C
Step-by-step explanation:
Every negative or positive number in the modulus while be positive at the end
The true statement is C) |–13| = 13, indicating that the absolute value of -13 is 13, representing the distance of -13 from zero on the number line.
How to Solve Absolute Value Equations?The true statement is: C) |–13| = 13, as explained below.
The expression |–13| represents the absolute value of -13, which is the distance of -13 from zero on the number line, always resulting in a non-negative value.
|–13| = 13, because the absolute value of -13 is 13, meaning it is 13 units away from zero on the number line. So, the correct option is C) |–13| = 13.

PLEASE HELP me with the magic square
Fill in each slot in the square with variables a, b, c, d, and e, in order from left-to-right, top-to-bottom. In a magic square, the sums across rows, columns, and diagonals all add up to the same number called the magic sum.
The magic sum is -3.9, since "diagonal 2" (bottom left to top right) has all the information we need:
3 + (-1.3) + (-5.6) = -3.9
Use this to find the remaining elements
row 1:a + b + (-5.6) = -3.9
row 2:c + (-1.3) + d = -3.9
row 3:3 + e + 0.02 = -3.9
column 1:a + c + 3 = -3.9
column 2:b + (-1.3) + e = -3.9
column 3:(-5.6) + d + 0.02 = -3.9
diagonal 1 (top left to bottom right):a + (-1.3) + 0.02 = -3.9
You will find
a = -2.62
b = 4.32
c = -4.28
d = 1.68
e = -6.92

If you were to roll a six-sided number cube 60 times, about how many times would you expect the number cube to land on a 1?
Answer:
10
Step-by-step explanation:
Probability is the likeliness of happening of an event.
Probability of any event A can be be defined by
no. of time event A happens/ total no. all possible event that can occur
___________________________________
In the problem
probability of occurrence of 1 on rolling a cube is needed.
A cube has six sides with one written on one sides and rest has 2,3,4,5,6.
No of times 1 can occur on rolling the dice once will be = 1
Since there six sides and and each has different number (1,2,3,4,5,6)
There is chance that each of the number can come.
Thus, total no possible outcome = 6
Probability of occurrence of 1 = No of times 1 occurs on rolling the dice /total no possible outcome = 1/6
_____________________________________________
If dice is rolled 1 time there is 1/6 chance that 1 will be the outcome.
If dice is rolled 1*60 time then there is 1/6*60= 10 chance that 1 will be the outcome
Thus , If you were to roll a six-sided number cube 60 times, about 10 times it is expected that the number cube to land on a 1.
