Answer:
The area of the base is <u>126 mm²</u>.
Step-by-step explanation:
Given:
A rectangular prism that has a 9mm width and 8mm height and a 14mm length.
Now, to find the area of the base of the rectangular prism.
The dimensions of rectangular prism are:
Length = 14 mm.
Width = 9 mm.
Height = 8 mm.
Now, to get the volume of rectangular prism by putting formula:
<u><em>Thus, the volume of rectangular prism is 1008 mm³.</em></u>
Now, to get the area of the base we put formula:
Dividing both sides by 8 we get:
Therefore, the area of the base is 126 mm².
(84÷7)+(9÷3) The parentheses are not necessary but I just put them.
I think that's what you meant. If you meant the other thing this would be the equation: (84÷7+9)÷3. Here the parentheses are nessasary
The prime factorization is 5 and 17 because those are the prime factors of 85
- ok so
- 16.(1+3) = 16 . 4 = 64
- so let's solve them
- A = (16 . 1) + (3 . 16) .. here it's right because we split the 6 on each number ... if you want a prove solve it (16 . 1 ) + (3 . 16 ) = 64
- B = (3+1) . 16 = 4 . 16 = 64
- C = (16 +3) . 1 = 19 . 1 = 19
- D = 161 + 163 = 324
so A & B = 64 .... so yeah right A & B are the correct answers
<em><u>by</u></em><em><u> </u></em><em><u>the</u></em><em><u> </u></em><em><u>way</u></em><em><u> </u></em><em><u>i </u></em><em><u>multiplied</u></em><em><u> </u></em><em><u>for</u></em><em><u> </u></em><em><u>the</u></em><em><u> </u></em><em><u>"</u></em><em><u>.</u></em><em><u>"</u></em><em><u> </u></em>
Yes the treasury can determine whether the gold bar is
really weighing 500 ounces.
We can use the equation:
7 x + 11 y = 500
where x is the amount of the 7 ounce weights while y is
the amount of 11 ounce weights.
We know that x and y should be whole numbers therefore
this is solved through trial and error.
By trial and error I got:
x = 7 and y = 41
<span>
So that;</span>
7 * 7 + 11 * 41 = 500
49 + 451 = 500
500 = 500
<span>Hence they can use 41 11-ounce weights and 7 7-ounce
weights to test</span>
