Answer:
See below.
Step-by-step explanation:
To calculate a percentage divide by the part by the whole, You will get a decimal. The decimal becomes a percentage after you multiply by 100. This moves the decimal place two places to the right. So 0.10 becomes 10%.
1. 20 is 50% of 40 since 20/40 = 0.5
2. 8/ 32 = 0.25 so it is 25%
3. 2/40 = 1/20 = 0.05 so it is 5%
4. 100/25 = 4 so it is 400%
5. 3/ 2 = 1.5 so 150%
To find a percentage of a number, multiply the number by the decimal conversion of the percent.
6. 0.15(300) = 45
7. 33/75 = 0.44 so it is 44%
8. 12/18 = 2/3 = 0.66 so it is 66%
9. 0.35(1000) = 350
10. 40 is 20% of what can be solved by remembering that 20* 5 = 100%. So 5*40 = 200. The number is 200.

Answer:
First term: <u>A(1) = 5 </u>
Fourth term: <u>A(4) = 5 1/2 </u>
Tenth term: <u>A (10) = 6 1/2</u>
Step-by-step explanation:
Let's find the first, fourth and tenth terms of the arithmetic sequence described by the given rule:
A(n) = 5 + (n-1) (1/6)
First term:
A(1) = 5 + (1-1) (1/6)
A(1) = 5 + (0) (1/6)
<u>A(1) = 5 </u>
Fourth term:
A(4) = 5 + (4-1) (1/6)
A(4) = 5 + (3) (1/6)
<u>A(4) = 5 + 3/6 = 5 3/6 = 5 1/2 </u>(simplifying)
Tenth term
A(10) = 5 + (10-1) (1/6)
A(10) = 5 + (9) (1/6)
<u>A (10) = 5 + 9/6 = 6 3/6 = 6 1/2</u> (simplifying)
Simplify \frac{5}{3}x35x to \frac{5x}{3}35x
x-\frac{5x}{3}<3x−35x<3
2
Simplify x-\frac{5x}{3}x−35x to -\frac{2x}{3}−32x
-\frac{2x}{3}<3−32x<3
3
Multiply both sides by 33
-2x<3\times 3−2x<3×3
4
Simplify 3\times 33×3 to 99
-2x<9−2x<9
5
Divide both sides by -2−2
x>-\frac{9}{2}x>−29
250*2 which gives your answer
