Answer: 
Step-by-step explanation:
You can use the following formula to calculate the surface area of the right rectangular prism:

Where "w" is the width, "l" is the length, and "h" is the height.
Knowing that this rigth rectangular prism has a length of 8 centimeters, a width of 3 centimeters and a height of 5 centimeters, you can substitute these values into the formula.
Then, the surface of the right rectangular prism is:
![SA = 2[(3cm*8cm) + (8cm*5cm) + (5cm*3cm)]\\\\SA=158cm^2](https://tex.z-dn.net/?f=SA%20%3D%202%5B%283cm%2A8cm%29%20%2B%20%288cm%2A5cm%29%20%2B%20%285cm%2A3cm%29%5D%5C%5C%5C%5CSA%3D158cm%5E2)
Answer:
the time taken is 22 mins
Answer:
Step-by-step explanation:
If J can paint a room in 3 hours, in 1 hour she gets
of the job done.
If A can paint a room in 4 hours, in 1 hour she gets
of the job done. We need to find out how long it takes them if they paint together. The equation for this is:
where x is the number of hours it takes them to get the job done together. Multiply everything through by 12x to get
4x + 3x = 12 so
7x = 12 and
x = 1.7 hours to get the room painted together.
Answer:
$54.6
Step-by-step explanation:
Amount borrowed = $560
Interest paid in the 12-month period = 6.5% of 560 =$36.4
The amount of interest Trudy pays in 18 months is worked out as
Monthly interest = $36.4/12
Interest payable in 18 months
= ($36.4/12) x 18
= $54.6
Answer:
a) 24
b) 10
c) 12/13
d) 5/13
e) 12/5
Step-by-step explanation:
a) We can see that the leg opposite <C is AB, and we are given AB = 24
b) We can see the leg adjacent to <C is AC, and we are given that AC = 10
c) The trig function sine is equal to

The opposite, AB, is 24, and the hypotenuse, BC, is 26. We can plug those numbers in:

d)The trig function cosine is equal to

The adjacent, AC, is 10, and the hypotenuse, BC, is 26. We can plug those numbers in:

d)The trig function tangent is equal to

The opposite, AB, is 24, and the adjacent, AC, is 10. We can plug those numbers in:
