Four milliliters of ink A is added to 10 milliliters of ink B, forming a mixture of inks. Ink A contains 10% blue pigment. Ink B contains an unknown percentage of blue pigment. The mixture of the two inks contains 35% blue pigment.

Answers

Answer 1

Answer: We will assume that B contains higher percentage of blue pigment than the mixture ( because A contains lower). First we will subtract:
35-10=15 and then: x-35
So we will make the proportion:
4 : 10 = (x-35) : 15
4 * 15 = 10(x-35)
60=10 x- 350
10 x =410
x = 41%
Answer: Ink B contains 41 % of blue pigment.

Henry wants to avoid interest capitalization on his $7,800 unsubsidized Stafford loan. Henry will graduate in four years, and the loan has a duration of ten years. The loan has an interest rate of 5.6%, compounded monthly. How much must Henry pay every month to avoid interest capitalization?

Answers

Interest capitalization means adding the interest to the principal balance. To avoid that you need to keep the balance at or below $7800. Let's assume Henry wants to pay the minimum amount necessary to avoid interest capitalization. Then, since it compounds monthly at an APR of 5.6%, each month a certain amount is added to the balance. That amount should be the yearly interest rate divided among the months in the year. Multiply that number by the principal to see how much interest accrues at the end of each month. That's what Henry needs to pay.

large cylinder: 12,924.24 m3
C.
small cylinder: 851.22 m3
large cylinder: 13,300.25 m3
D.
small cylinder: 682.95 m3
large cylinder: 13,539.68 m3

Answers

r1² π : r2² π = 9 : 1.44
r1 : r 2 = 3 : 1.2
r2 = 1.2 · r1 / 3
r 2 = 0.4 · r1
If the two cylinders are similar than also: h 2 = 0.4 · h 2
V 1 = r1² · π · h1
V 2 = ( 0.4 r1)² π · 0.4 · h1 = 0.064 r1² · π · h1
V 2 ( small cylinder )= 0.064 · V 1 ( large cylinder )
851.22 m³= 13.300.25 m³ · 0.064
Answer: C )

What is 3/8 written as a percent? 3/8 = 0.375 * 100 = 37.5%

Answers

To convert a fraction to a percentage, multiply it by 100 and add the percent (%) sign.

$(3)/(8)* 100 = (300)/(8) =(150)/(4) =(75)/(2) = 37.5$

So 3/8 is 37.5%.

If you would like to know what is 3/8 written as a percent, you can calculate this using the following steps:

3/8 = 375/1000 = 0.375
0.375 * 100 % = 37.5%

The correct result would be 37.5%.
