Find the surface area of this rectangular prism: Don't forget to show the unit of measure.
Ann [662]

Answer:

See Explanation

Step-by-step explanation:

The question is incomplete as the attachment of the prism is not given.

From the attachment:

L =10cm -- Length

W = 4cm -- Width

H=5cm -- Height

Required

Determine the volume

So, the volume is:

Volume = Length * Width (* Height

Volume = 10cm * 4cm * 5cm

Volume = 200cm^3

What is the difference between Compound Interest and simple interest???
oksian1 [2.3K]

Answer:

Simple interest is calculated using initial principle while compound interest is calculated considering the interest also .

Step-by-step explanation:

Interest is the cost of borrowing money, where the borrower pays a fee to the lender for using his money. The interest, typically expressed as a percentage, can either be compounded or simple .

Simple interest is based on the principal amount , while compound interest is based on the principal amount and the interest that adds onto it in every period and the final principle is used for calculating the interest.

Simple interest is calculated  on the principal amount of a loan and it's easier to find out than compound interest.

Draw a line that connects each table to the correct graph
stealth61 [152]

Answer:

For number 1, you draw a line to the middle graph

For number 2, you draw a line to the bottom graph

For number 3, you draw a line to the top graph.

Step-by-step explanation:

To figure out where the graph goes, you only need to know if the point is on the graph. For the top graph, you know that the point 2,2 is on the graph so that means one part of the graph has to be 2 and 2. The x has to equal to and the y is equal 2. Therefore, you have to draw it to the bottom graph.

Some farms use a hay elevator to move bales of hay to the second story of a barn loft. The bottom of the elevator is 9 meters fr
-Dominant- [34]

Answer: The height is 6.07 meters

Step-by-step Explanation: The distance between the elevator and the bottom of the barn is given as 9 meters. Also for the hay elevator to move bales of hay to the second story of the barn lift it makes an angle of elevation of 34 degrees with the ground. With these we can derive a right angled triangle with the reference angle as 34 degrees, the side facing it which is the height or h (opposite) is yet unknown, and the side between the reference angle and the right angle (adjacent) is 9. We shall apply the trigonometric ratio as follows;

Tan 34 = opposite/adjacent

Tan 34 = h/9

0.6745 = h/9

0.6745 x 9 = h

6.0705 = h

Therefore the approximate height of the barn to the ground is 6.07 meters

Find the missing side
dybincka [34]

Answer:

7) 8.94

8) 6.71

Step-by-step explanation:

for both questions, use pythagorean theorem

a^{2} + b^{2} = c^{2}

<u>Question 7:</u>

4^{2} + 8^{2} = c^{2}

16 + 64 = c^{2}

80 =  c^{2}

\sqrt{80} = \sqrt{c^{2}}

c = 8.94

<u>Question 8:</u>

6^{2} + 3^{2} = c^{2}

36 + 9 = c^{2}

45 = c^{2}

\sqrt{45} = \sqrt{c^{2} }

c = 6.71
