Step-by-step explanation:
Answer:
k=62
Step-by-step explanation:
K divided by 5 = 12.4
Multiply both sides by 5
5k/5=12.4×5
Simplify;
k=62
Hope this helped!!
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.
13: multiply the amount by the tax rate (to make a percent a decimal move the decimal point 2 places to the left) and add the original amount and the taxed amount together. For 12 do above but then multiply the total by the tip rate and add together (basically the same as the tax again) :) I hope this helps
Answer:
3
Step-by-step explanation:
You'll need to use the Angle Bisector Theorem.
CU / ZU = BC / BZ
From the first part of the problem, you used Pythagorean theorem to find that BZ = 10.
Let's say that CU = x. That means ZU = 8 − x. Plugging in values:
x / (8 − x) = 6 / 10
Cross multiply:
10x = 6(8 − x)
Solve:
10x = 48 − 6x
16x = 48
x = 3
