Final answer:

Fredric's gross pay for working 46 hours at an hourly rate of $8.50 is $391.00.

Explanation:

The question asks about calculating Fredric's gross pay given the number of hours he worked and his hourly rate. To find Fredric's gross pay, we multiply the number of hours worked by his hourly rate.

Fredric worked 46 hours last week and his hourly rate is $8.50. Therefore,

Gross Pay = Hours Worked × Hourly Rate

= 46 hours × $8.50/hour

= $391.00

So, Fredric's gross pay for the week is $391.00.

Fredric's gross pay for working 46 hours at $8.50 per hour is $391.00.

To find Fredric's gross pay, we multiply his hours worked by his hourly rate.

1. **Calculate total earnings for the week:**

[tex]\[ \text{Total earnings} = \text{Hours worked} \times \text{Hourly rate} \][/tex]

[tex]\[ \text{Total earnings} = 46 \text{ hours} \times \$8.50/\text{hour} \][/tex]

2. **Perform the multiplication:**

 [tex]\[ \text{Total earnings} = 46 \times \$8.50 \][/tex]  

[tex]\[ \text{Total earnings} = \$391.00 \][/tex]

So, Fredric's gross pay for the week was $391.00.

Step-by-step explanation: 16 girls means that there are 8 boys. 8+16=24.

Answer:

To solve -5/6 + (-1/12), convert both to have a common denominator of 12, resulting in -10/12 + (-1/12). Add the numerators to get -11/12. The sum of two negative fractions maintains a negative sign.

To find the answer to the problem -5/6 + (-1/12), we need to add the two fractions. When adding fractions with different denominators, we first find a common denominator. In this case, the common denominator for 6 and 12 is 12. We then convert each fraction to an equivalent fraction with this common denominator.

For the first fraction -5/6, we multiply both the numerator and the denominator by 2 to get -10/12. The second fraction is already with a denominator of 12, so we keep it as -1/12. Now, we add the numerators while keeping the denominator the same:

-10/12 + -1/12 = -11/12. The sum of the two fractions is -11/12, which is already in simplest form.

This example demonstrates that when two negative numbers add, the answer has a −ve sign, and the numerators are simply added together while the denominator remains the same.

For direct variation, represented by y = kx, we replace y and x with the provided values. We solve for k to get 36. The direct variation equation is y = 36x.

In the case of direct variation, the equation is usually presented in the form of y = kx, where k is the constant of variation. To write an equation to represent the direct variation between x and y with the given values, we will begin by replacing y and x in our equation with the given values 12 and 1/3 respectively.

That gives us 12 = k(1/3). By solving for k, we obtain k = 12 / (1/3) = 36. Thus, the equation representing the direct variation between x and y is y = 36x.

  - The diagram bar is attached.

  - Addition equation:  [tex]7+7+7=21[/tex]

  - Multiplication equation: [tex](3)(7)=21[/tex]

  -  How are the equation related? Each equation shows 3 groups of 7.

Step-by-step explanation:

We know that Jan buys 3 bags of beads and each bag contains 7 beads, then, you can draw the bar diagram shown attached.

 Observe that the diagram has 3 blocks (each block represents a bag of bead) and there is a number 7 inside of each block (which is the number of beads contained in a bag).

Therefore:

- Add the numbers inside the blocks in order to get the addition equation that shows the number of  beads Jan buys. This is:

[tex]7+7+7=21[/tex]

- Multiply 3 blocks by 7 in order to get multiplication equation that show the number of beads Jan buys:

[tex](3)(7)=21[/tex]

The equations are related. Each one shows 3 groups of 7.

Step-by-step explanation:

Answer:

It costs $0.14 to drive your car for one mile.

Hope this helps :)

To calculate the cost of driving per mile, the price of gasoline ($4.2) should be divided by the car's fuel efficiency (30 mpg). This results in a cost of $0.14 per mile.

To find out how much it costs to drive per mile, we need to divide the cost of one gallon of gas by the number of miles that can be driven with that gallon. In this case, the cost of gasoline is $4.20 per gallon and the mileage of the car is 30 miles per gallon.

So, in this scenario, it costs approximately $0.14 to drive your car for one mile on the highway.

By definition:

Odd numbers cannot be divided by 2 evenly

Examples are

Answer:

Step-by-step explanation:

You are copying a square of side 20 inches into a smaller version of it that is exactly 25% of the original size.

Notice that 25% can be written in fraction form as: [tex]\frac{25}{100} = \frac{1}{4}[/tex]

This gives us a clue about how to reduce the original dimension: "multiply it by [tex]\frac{1}{4}[/tex], which is the same as divide it by 4:

Answer: 218

Step-by-step explanation:

(y - yo) = m.(x - xo)

Let's go

(-1/n - (-1/m)) = s.(1 - n/m)

(-1/n + 1/m) = s.(1 - n/m)

(-m+n)/mn = s.(m - n)/m

If we multiply both sides by m

(-m + n)/n = s.(m - n)

If we take the (-1) from the left side we have

(-1.(m - n))/n = s.(m - n)

And if we divide both sides by (m - n)

-1/n = s

So our slope is -1/n

Answer:

Step-by-step explanation:

If Chad had 7 sandwiches and that was 6 fewer than the amount Sarah has then Sarah made 6 sandwiches. The working is as follows :

Chad = 7 sandwiches (6 fewer than Sarah)

Sarah = ?

Sarah = 7 + 6 = 13 sandwiches.

In order for Chad to have eaten that many sandwiches, Sarah would have had to have made 13 sandwiches.

Sarah made x number of sandwiches and Chad ate 7 out of it.

The 7 that Chad ate remained 6 sandwiches out of the total that Sarah made.

The number of sandwiches Sarah made is therefore:

= Number that Chad ate + Number that was left

= 7 + 6

= 13 sandwiches

In conclusion, Sarah made 13 sandwiches

use the substitution method

y=3x-5

y= 1/2x+5

3x-5= 1/2x+5

move -5 to the other side

sign changes from -5 to +5

3x-5+5= 1/2x+5+5

3x= 1/2x+10

move 1/2x to the other

3x-1/2x= 1/2x-1/12x+10

3x-1/2x= 10

find the common denominator for 3x

pretend that there is a 1 for 3x. 3x/1. The common denominator is 2. Mutiply the fraction by 2

3x(2)/1(2)

= 6x/2

6x/2-1/2x= 10

5/2x= 10

mutiply both sides by 2/5

5/2x(2/5)= 10(2/5)

Cross out 5 and 10, divide by 5 . Then becomes 2*2= 4

Answer: (4,7)

To find the ordered pair (x, y) that satisfies the given equations y=3x-5 and y=1/2x+5, we can solve the system of equations simultaneously. The ordered pair is (4, 7).

To find the ordered pair (x, y) that satisfies the given equations y=3x-5 and y=1/2x+5, we need to solve the system of equations simultaneously. By setting the two expressions for y equal to each other, we can find the x-coordinate. Substituting this value back into either equation will give us the y-coordinate.

Let's set 3x-5 equal to 1/2x+5:

3x-5 = 1/2x+5

Multiplying through by 2 to eliminate the fraction:

6x-10=x+10

Combining like terms:

5x=20

Dividing both sides by 5:

x=4

Substituting this value of x into y=3x-5:

y=3(4)-5

y=12-5

y=7

Therefore, the ordered pair (x, y) is (4, 7).

Answer:

2:5

Step-by-step explanation:

8:20 divided by 4 on bothe sides would equal 2:5

Equivalent ratios to 8:20 can be found by simplifying this ratio to its lowest terms, which is 2:5, and then scaling these numbers up or down by the same factor. Examples of equivalent ratios to 8:20 include 2:5, 4:10, 6:15, 8:20, and 10:25.

The question is asking for ratios equivalent to the ratio 8:20. To find equivalent ratios, we need to either multiply or divide both numbers in the ratio by the same amount. Ratios are a method of comparing quantities and numbers.

Let's start by simplifying the ratio 8:20 to its simplest form. To do this, we find the greatest common divisor of 8 and 20 which is 4. Then, divide both numbers by 4. This simplifies the ratio to 2:5.

Now that we have the simplified form of the ratio, we can find equivalent ratios by simply multiplying or dividing these numbers by any other number. For instance, multiplying by 2, we get the ratio 4:10. This is an equivalent ratio to 8:20 because the relationship between the numbers remains the same.

Here are some other equivalent ratios to 8:20: 6:15, because 2 x 3 = 6 and 5 x 3 = 15; 8:20, because 2 x 4 = 8 and 5 x 4 = 20; and 10:25, because 2 x 5 = 10 and 5 x 5 = 25.

Step-by-step explanation:

You can use a proportion.

To make it easier to write the proportion, we rewrite the numbers as decimals.

3/4 = 0.75

Let x be the unknown amount of sugar.

3.5 cups of flour is to 0.75 cup of sugar as 6 cups of flour is to x cups of sugar.

3.5/0.75 = 6/x

Cross multiply.

3.5x = 4.5

x = 4.5/3.5 = 45/35 = 9/7 = 1 2/7
