Answer: the answer is number four.
Step-by-step explanation:
<h2>because when you take five multiply by A (5*a) you will get 5a and when you take five multiply by six (5*6) you will get 30 and there is positive sign so the plus (+) stays the same and your will be (5a+30) that is your answer. good luck.</h2>
Answer:
9 ft, 28 ft, 26 ft
Step-by-step explanation:
The perimeter is the sum of side lengths, so ...
P = a + b + c
63 = n +(4n -8) +(2n +8) . . . . fill in the given side lengths
63 = 7n . . . . . . simplify
9 = n . . . . . . . . divide by 7
4n -8 = 36 -8 = 28 . . . . second side length
2n +8 = 18 +8 = 26 . . . . third side length
The side lengths are 9 ft, 28 ft, 26 ft..
Answer:
The surface area of the prism is <u>480 in²</u>.
Step-by-step explanation:
Given:
The prism dimensions are 8in 15in 17in and 9in.
Now, to find the surface area:
So, to get the surface area we put formula:
a=8in, b=15in, c=17in and h=9in.
Surface area = 2A+(a+b+c)h.
Whereas, 
And, 
<em>Now, we find </em><u><em>s</em></u><em> first:</em>
<em>Then, we get</em><u><em> A </em></u><em>:</em>
<em>On solving we get:</em>
Now, putting the value of A in the formula to get the surface area:
Therefore, the surface area of the prism is 480 in².
Answer: 40
Step-by-step explanation:
16 + 24
= 8(2) + 8(3)
= 8(2 + 3)
= 8(5)
=40
From the title of your worksheet, you have to convert improper fractions to proper fractions. So, you see those two numbers on the top and the bottom separated by a line? Those are fractions. For example, 12/4 is an improper fraction.(I can't use the exact 'line' that separates it as its not on my keyboard, so I'm just using '/'.) In 12/4, 12 is 'on top'. The number on top is the numerator. And the number on the bottom, 4, is the denominator. 12/4 is an improper fraction as the numerator is bigger than the denominator. So, you can divide 12 by 4, giving you 3. 3 is a whole number as 12 could be divided by 4 without remainder, so that's your answer if you wanted to convert it into a proper fraction. That's just an example, though. Another example for things that have remainder when divided; let's use 13/4 for this example. 13 can't be divided by 4 perfectly, so you use the closest number that can be divided by 4, which is 12. But what happens to the the number left after using 12? 13-12=1. That's where the fraction comes along. The denominator was 4 in 13/4 so the proper fractions that you get is 3(the whole number) and 1/4(the one left after using 12).
So, for that example, your answer's 3 1/4.(note that the whole number should be bigger than the fraction when you write it out.)
Sorry for this really long answer. I didn't want to just give you the answer without you understanding it.
Anyway, for your questions in your worksheet.
I'm starting from question 1 and not the example question in your worksheet.
1) 4 5/8
2) 10 3/10
3) 6 2/4
Or in simplest form if required: 6 1/2
4) 3 1/3
5) 5 3/8
6) 3 6/7
7) 10 9/10
8) 7 1/3
9) 7 4/5
10) 2 4/5
11) 4 1/2
12) 5 1/3
13) 9 2/8
Or in simplest form if required: 9 1/4
14) 5 2/3
15) 8 9/10
16) 8 3/4
17) 10 1/6
18) 1 2/6
19) 7 3/6
20) 10 7/10
( I put some spaces between the whole numbers and fractions so that it's not too complicating.)
I apologize if I made any mistakes ^^;;
Happy learning! :)
