Natalija [7]2 years ago

A percentage is a way to describe a part of a whole. The percentage of 4c that is equal to 0.04c is 1%.

<h3>What are Percentages?</h3>

A percentage is a way to describe a part of a whole. such as the fraction ¼ can be described as 0.25 which is equal to 25%.

To convert a fraction to a percentage, convert the fraction to decimal form and then multiply by 100 with the '%' symbol.

The percentage of 4c that is equal to 0.04c can be found as,

x% of 4c = 0.04

(x/100) × 4c = 0.04

x = \dfrac{0.04c \times 100}{4c}

x = 1%

Hence, the percentage of 4c that is equal to 0.04c is 1%.

Hi. If you need me to explain please tell me so I will edit this comment. I'll just solve the answers for you... basically if they have a common denominator just add/ subtract, and if they don't, make it so they do by multiplying the same on each side.

2)
a. 1 3/4 + 2 1/4 = 4
b. 3 7/10 + 1 1/10 = 4 4/5
c. 2 1/8 + 3 3/8 = 5 1/2
d. 5 1/2 + 3 1/4 = 8 3/4
e. 5/8 + 2 1/4 = 2 7/8
f. 3 3/10 + 5 2/5 = 8 7/10

3)
a. 2 7/10 - 1 3/10 = 1 2/5
b. 3 5/8 - 2 3/8 = 1 1/4
c. 1 5/6 - 1/6 = 1 2/3
d. 3 7/10 - 1 1/2 = 2 1/5
e. 4 3/5 - 2 = 2 3/5
f. 1 3/8 - 1 1/8 = 1/4

y is directly proportional to x^3. it is known that =5 for a particular value of x. find the value of y when this value of y whe
alina1380 [7]

Answer:

The value of y when the value of x is multiplied by \frac{1}{2} is \frac{5}{8}.

Step-by-step explanation:

According to the statement, we have the following relationship:

y = k\cdot x^{3} (1)

Where:

x - Independent variable.

y - Dependent variable.

k - Proportionality constant.

We can eliminate the proportionality constant by constructing the following relationship:

\frac{y_{2}}{y_{1}} = \left(\frac{x_{2}}{x_{1}} \right)^{3}

If we know that y_{1} = y, y_{2} = 5, x_{2} = x_{o} and x_{1} = \frac{1}{2}\cdot x_{o}, then the value of y when the value of x is multiplied by \frac{1}{2} is:

\frac{5}{y} = \left(\frac{x_{o}}{\frac{1}{2}\cdot x_{o} } \right)^{3}

\frac{5}{y} = 8

y = \frac{5}{8}

The value of y when the value of x is multiplied by \frac{1}{2} is \frac{5}{8}.

What happens to the value of the expression 150-j150−j150, minus, j as jjj decreases?
nikklg [1K]

Answer:

The value of the expression increases as j decreases

Step-by-step explanation:

Let f(j) = 150 - j150 - j150

f(j) = 150 - j300

As j decreases, the value of j300 decreases (i.e the farther j300 is from 150). Due to the wider gap between 150 and j300, the value of f(j) increases.

For example:

When j = 1, f(j) = 150 - (300*1) = -150

When j = 0.5, f(j) = 150 - (300*0.5) = 0

When j = 0. f(j) = 150 - (300*0) = 150

It is obvious from the analogy above that the expression 150-j150−j150 increases as j decreases
