Rachel has 75 books.18 of the books are comics books. The rest of books are novels.
a. What percentage of the books are novels?
b. What percentage of her books are comics?

Answers

Answer:

Novels: 24% Comics: 76%

Step-by-step explanation:

Divide 18/75= 0.24= 24% to find percent of novels

Subtract 100-24= 76 to get the remaining percent

Or

Subtract 75-18= 57 (to get the number of comics she has)

Divide 57/75= 0.76= 76% to find percent of comics

what is the value of 4/15 ÷ 2/3​

Answers

The answer should be 2/5

When you divide fractions you multiply by the reciprocal.

So you do 4/15 divided by 2/3 get the reciprocal of 2/3 and you have 3/2. 3 would become the nominator and 2 would become the denominator.

So then you would multiply right across 4/15 x 3/2, it would look like 4x3 and 15x2. (4x3=12) (15x2=30)

Then you’d get 12/30 which can be simplified it by 2 it’d be 6/15 but if you simplify it again by 3 you get your final answer 2/5

You know your done simplifying when both the nominator and denominators are prime numbers meaning they can only be divisive ale by 1 and itself

The value of 4/15 ÷ 2/3 is 2/5

In order to solve this, the first thing is to change the division sign to multiplication sign and this will be:

= 4/15 ÷ 2/3

= 4/15 × 3/2

= 12/30

Reduce to lowest term

12/30 = 2/5

In conclusion, the value of 4/15 ÷ 2/3 is 2/5.

You deposit $20 in a savings account. The account earns 4% simple interest per year. What is the balance after 4 years?

Answers

Answer:

$23.20

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 4%/100 = 0.04 per year,

then, solving our equation

I = 20 × 0.04 × 4 = 3.2

I = $ 3.20

The simple interest accumulated

on a principal of $ 20.00

at a rate of 4% per year

for 4 years is $ 3.20.

Based on the calculations, your balance after four (4) years is equal to $23.2.

Given the following data:

Interest rate = 4% = 0.04.Principal = $20.Time = 4 year

To determine the balance after four (4) years:

How to calculate simple interest.

Mathematically, simple interest is given by this formula:

[tex]I = PRT[/tex]

Where:

S.I is the simple interest.P is the principal or starting amount.R is the interest rate.T is the time measured in years.

Substituting the given parameters into the formula, we have;

[tex]I=20 \times 0.04 \times 4[/tex]

Simple interest = $3.2.

Balance = [tex]3.2 +20[/tex] = $23.2.

PLS HELP ASAP If -2 is added to each of the x and y intercepts of the line 3x + 2y = 6, find the new equation of the line

Answers

Answer:

3x + 2y = -4

Step-by-step explanation:

x intercept of the line occurs at y = 0

Given the equation 3x+2y = 6

3x+2(0) = 6

3x  = 6

x = 2

The x intercept is at (2, 0)

Adding -2 to each axis will give (2-2, 0-2) = (0, -2)

y intercept of the line occurs at x = 0

Given the equation 3x+2y = 6

3(0)+2y = 6

2y  = 6

y =3

The x intercept is at (0, 3)

Adding -2 to each axis will give (0-2, 3-2) = (-2, 1)

The new coordinates are (0, -2 and (-2, 1)

Using the point slope form of the equation y - y0 = m(x-x0)

slope m = y2-y1/x2-x1

m = 1-(-2)/-2-0

m = 1+2/-2

m = -3/2

Using m = -3/2 and (0, -2)

y - (-2) = -3/2(x-0)

y+2 = -3/2 x

2(y+2) = -3x

2y+4 = -3x

-3x-2y = 4

3x + 2y = -4

Hence the required equation is 3x + 2y = -4

Answer:

1a. 3y = 18

1b. y + 7 = 18

1c. 2y + 4 = 18

Step-by-step explanation:

In each case, let's take the red boxes to be constant why the the green boxes represents the variable, y.

Thus,

1a. There are only 3 green boxes which gives us 18, therefore, the equation that expresses this would be:

3y = 18

1b. We have 7 red boxes which represents the constant, 7.

We also have 1 green box which represents the variable, y. Therefore, the equation that expresses this would be:

y + 7 = 18

1c. We have 4 red boxes = 4

We have 2 green boxes = 2y

Therefore, we would have:

2y + 4 = 18

the length of a rectangle is 6 meters more than its width. if the area of the rectangle is 135 square meters, find its dimensions, PLEASE explain and show steps

Answers

Answer:

length 15 width 9

Step-by-step explanation:

Then the length can be represented by the following expression: (x + 6)

Since area is equal to length times width, we can write the following equation for the area:

A = length * width

135 = (w + 6) * w

Now we can solve for w after using the distributive property and factoring:

135 = (w + 6) * w

135 = w^2 + 6w

0 = w^2 + 6w - 135

This factors to:

0 = (w + 15) (w -9)

w = -15 OR w = 9
