what is -4/5 + 3/20 in simplest form

Answers

Answer 1
-4/5 = -16/20, so the new expression is (-16/20)+(3/20)
then, -16 + 3 is -13, so the solution is -13/20
Answer 2
-4/5 + 3/20 = 3/20 - 4/5

To subtract 2 fractions, they both need to have the same denominator.
Since 5 is one of the divisors of 20, we can just multiply the numerator and denominator of 4/5 by 4.
4/5 = (4*4) / (5*4) = 16/20

P.S. when the denominators of both fractions don't have any relation, you multiply the numerator and denominator of the first fraction by the denominator of the second, and the numerator and denominator of the second by the denominator of the first.

3/20 - 4/5 = 3/20 - 16/20

Now you just subtract the numerators:
3/20 - 16/20 = (3-16)/20 = -13/20

So -4/5 + 3/20 = -13/20

Hope this helps! :)

Relationship A has a lesser rate than Relationship B. This table represents Relationship B.

Hours worked 2 4 5 8
Amount paid ($) 36.50 73 91.25 146
Which equation could represent Relationship A?

Hours worked is represented by x and Amount paid is represented by y.

Select each correct answer.

y = 18.1x

y = 18.6x

y = 18.3x

y = 18x

Answers

Answer:

y = 18.1x ; and y = 18x

Explanation:

The rate of change in Relationship B can be found by using the formula for slope:

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

Using the first two points, we have

[tex]m=\frac{73-36.50}{4-2}=\frac{36.50}{2}=18.25[/tex]

We know that Relationship A has a lesser rate than this.  The choices given for Relationship A are written in slope-intercept form, y=mx+b, where m is the slope and b is the y-intercept (in this case b = 0).

The slope of the first equation is 18.1; this is less than 18.25.

The slope of the second equation is 18.6; this is greater than 18.25.

The slope of the third equation is 18.3; this is greater than 18.25.

The slope of the fourth equation is 18; this is less than 18.25.

Answer:

Option A and D.

Step-by-step explanation:

If a linear function passes through two points, then the rate of change is

[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]

From the given table it is clear that the Relationship B have two ordered pairs (2,36.50) and (4,73). So, the rate of Relationship B is

[tex]m=\dfrac{73-36.50}{4-2}[/tex]

[tex]m=\dfrac{36.50}{2}[/tex]

[tex]m=18.25[/tex]

The rate of relation B is 18.25.

Let hours worked is represented by x and amount paid is represented by y. So the Relationship B is defined as

[tex]y=kx[/tex]

Where, k is the rate of relationship A.

It is given that Relationship A has a lesser rate than Relationship B.

[tex]k<18.25[/tex]

We know that

[tex]18.1<18.25[/tex], [tex]18.6>18.25[/tex], [tex]18.3>18.25[/tex] and [tex]18<18.25[/tex].

The relationship A could be

[tex]y=18.1x[/tex] and [tex]y=18x[/tex]

Therefore, the correct options are A and D.

Mt. Everest rises 54768 feet in the air while Mt. Rushmore stretches a mere 8976 feet . What is the difference in the height of these two mountains expressed in scientific Notation?

Answers

so first, 54,768 - 8976 = 45,792.
In scientific notation, that would be 4.5792 x 10^4
Final answer:

The difference in height between Mt. Everest and Mt. Rushmore is 45,792 feet expressed in standard notation and 4.5792x10^4 feet in scientific notation.

Explanation:

The student is asked to calculate the difference in height between Mt. Everest and Mt. Rushmore and express that difference in scientific notation. The height of Mt. Everest is 54,768 feet and the height of Mt. Rushmore is 8,976 feet. To calculate the difference in height, subtract the height of Mt. Rushmore from the height of Mt. Everest: 54,768 feet - 8,976 feet = 45,792 feet.

To express this difference in scientific notation, move the decimal point to just after the first digit (4), resulting in 4.5792. Then count how many places you moved the decimal. In this case, it moved 4 places, so the exponent is 4. Therefore, the difference in height between Mt. Everest and Mt. Rushmore is approximately 4.5792x10^4 feet in scientific notation.

Final answer:

In a cinema with 120 rows and 75 seats in each row, we can find the total number of seats by multiplying these two numbers together. This results in 9000 total seats.

Explanation:

The subject of this question is related to a real-world mathematical problem. Suppose there is a cinema having 120 rows and each row consists of 75 seats. We want to find out the total number of seats in the cinema hall.

To solve this, we need to use multiplication. In mathematics, multiplication is one of the four elementary mathematical operations, with the other three being addition, subtraction, and division. By multiplying 120 (the number of rows) with 75 (the number of seats in each row), you can find out the total number of seats in the cinema hall.

So, 120 * 75 = 9000. Hence, there are 9000 seats in the cinema.

Carmen has 18 connecting cubes. She wants to model a house shaped like a rectangle. If the model has a height of one connecting cube, how many different ways can Carmen model the house using all 18 connecting cubes?

Answers

Final answer:

To determine the number of ways Carmen can model the house using all 18 connecting cubes, considering them as distinguishable objects and applying permutations is essential.

Explanation:

Carmen has 18 connecting cubes and wants to model a house shaped like a rectangle with a height of one connecting cube. To find the number of ways to model the house using all 18 cubes, we can approach it using combinatorics. One way to visualize this is by considering the cubes as distinguishable objects and applying permutations.

One approach could involve fixing the base of the rectangle, which will have a length of 16 cubes, leaving 2 cubes for the width. The 2 remaining cubes can be placed in 2! = 2 ways. So, the total number of ways to model the house would be 16!×2.

Answer:

There are 3 ways.

Step-by-step explanation:

Let each cube be 1 cm on the side.

The volume of each cube is 1 cm³.

volume = length × width × height

We are told the height is 1.

The volume is 18 cubes, so volume = 18 cm³.

length × width × height = 18 cm³

length × width × 1 cm = 18 cm³

length × width = 18 cm³

There are 3 ways to factor 18 into integer factors:

1, 18

2, 9

3, 6

Carmen can make the model 18 cubes long by 1 cube wide,

or 9 cubes long by 2 cubes wide, or 6 cubes long by 3 cubes wide.

Answer: There are 3 ways.

How many times greater is 7,000 than 70

Answers

Final answer:

To find out how many times greater 7,000 is than 70, one needs to perform a division operation. In this case, it would be 7,000 divided by 70 which equals 100. Hence, 7,000 is 100 times greater than 70.

Explanation:

To determine how many times greater 7,000 is than 70, one must use division. This is done by dividing 7,000 by 70. The equation would look like this: 7,000 ÷ 70. If you solve the equation, the answer is 100. Therefore, 7,000 is 100 times greater than 70.

This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.

Based on the problem, we can see that the original cost of the product cannot be more than 75 which means that it can be equal to 75 or less than 75. We can actually express the inequality as x< or = 75 since we are looking for the cost before Chet applied the $25 gift certificate.

Hello,

To set up the equation, you would do: 2x - 3 = x + 4.

Let's add 3 from the left side to the right, it would then be: 2x = x + 7.

We then want that "x" from the right side to be with the "2x", so we will subtract "x" from the right to cancel it out, and then we will subtract "x" to other side too.

After you do that, the equation should be: x=7. This is the final answer. Hope this helps!
