Answer:

B, H

Step-by-step explanation:

The electrician charges 45 dollars per hour and 30 at the beginning. We are multiplying the hours, h, by 45 to get 45h. We add 30 to get C=45h+30

Jerome will always earn 75 dollars, but he also gets 10 percent commission, which is 0.10.

Answer:

B and H are the correct answers

Answer:

B

Step-by-step explanation:

Given

[tex]\frac{4}{2}[/tex] = [tex]\frac{3}{x}[/tex] ( cross- multiply )

4x = 6 ( divide both sides by 4 )

x = 1.5 → B

Answer:

3/2 0r B. 1 1/2

Step-by-step explanation:

Step 1: Cross-multiply.

4/2=3/x

4*x=(3)*(2)

4x=6

Step 2: Divide both sides by 4.

4x/4=6/4

x=3/2

Answer:

x=3/2

3/2 is an equivilant to B 1.5 or 1 1/2

Answer:

a) Area = 2x² + 3x - 2

b) Perimeter = 64x + 28

c) Length = 60 feet and Width = 50 feet

Step-by-step explanation:

It is given that:

Length of building = 12x + 24

Width of building = 20x - 10

Area = Length * Width

Area = (12x + 24) * (20x - 10)

Area = 12x(20x - 10) +24(20x-10)

Area = [tex]240x^2-120x+480x-240[/tex]

Area = [tex]240x^2+360x-240 = 2x^2+3x-2[/tex]

Perimeter = 2 (Length + Width )

Perimeter = 2 (12x + 24 + 20x - 10 ) = 2 (32x +14 )

Perimeter = 64x + 28

Putting Perimeter = 220

220 = 64x + 28

64x = 220 - 28

64x = 192

Dividing both sides by 64

x = 3

Length = 12(3) + 24 = 36 + 24 = 60 feet

Width = 20(3) - 10 = 60 - 10 = 50 feet

Therefore,

a) Area = 2x² + 3x - 2

b) Perimeter = 64x + 28

c) Length = 60 feet and Width = 50 feet

The given statement is false because a quadratic equation may have no solutions, one solution, or two solutions, regardless of whether it can be factored or not.

The quadratic equation is defined as a function containing the highest power of a variable is two.

A quadratic equation is a type of polynomial equation that can be written in the form ax² + bx + c = 0, where a, b, and c are constants and x is a variable.

If a quadratic equation cannot be factored, it does not mean that it does not have any solutions.

A quadratic equation may have no solutions if the discriminant, which is the quantity b² - 4ac, is less than zero.

In this case, the quadratic equation has no real solutions, as the solutions would be complex numbers.

However, if the discriminant is equal to zero, the quadratic equation has one solution, which is the value of x that makes the equation equal to zero. If the discriminant is greater than zero, the quadratic equation has two solutions, which are the values of x that make the equation equal to zero.

In summary, a quadratic equation may have no solutions, one solution, or two solutions, regardless of whether it can be factored or not.

Thus, the given statement is false.

Answer:

f=-1/9

Step-by-step explanation:

Answer:

First, isolate the variable, f. Subtract 4 to both sides to result with 2f > -7f -1.

Then, add 7f to both sides to result with 9f > -1. Now, we can divide 9 to both sides to get f > -1/9.

Answer:

2 1/6

Step-by-step explanation:

2 3/5 x 5/6

convert the 2 3/5 to an improper fraction so it can be easier to multiply

2 3/5 = 13/5

13/5 * 5/6

All you need to do is multiply across. Both denominators, and both numerators.  

13 * 5 = 65 (numerator)

5 * 6 = 30 (denominator)

65/30 and that is in an improper form

2 5/30 = 2 1/6 = In a simplified mixed number

2 1/6

Answer:

Step-by-step explanation:

That depends on how many sections there are. If there are 2 sections, then it will be a 50/50 chance it lands on 1 if there are 3 sections then it would be 1/3 or for 4, 1/4, and for 5, 1/5, etc.

The theoretical probability of spinning a 1 is 1/4.

Probability is simply the possibility of getting an event. Or in other words, we are predicting the chance of getting an event.

The value of probability will be always in the range from 0 to 1.

Theoretical probability is the probability that we find through the theoretical approach without doing the experiment.

Total number of sections that the spinner has = 4

Number of sections numbered  1 = 1

Probability of spinning a 1 = 1/4

Hence the required probability = 1/4.

Answer:

0.51

Step-by-step explanation:

Given:

Principal= $6000

Rate of interest = 2.1% compounded quarterly.

To find:

The balance after one year.

Solution:

The formula for amount is:

[tex]A=P\left(1+\dfrac{r}{n}\right)^{nt}[/tex]

Where, P is principal, r is rate of interest, n is number of times interest compounded in an year and t is number of years.

We have, P=6000, r=0.021, n=4 and t=1.

Putting these values in the above formula, we get

[tex]A=6000\left(1+\dfrac{0.021}{4}\right)^{4(1)}[/tex]

[tex]A=6000\left(1+0.00525\right)^{4}[/tex]

[tex]A=6000\left(1.00525\right)^{4}[/tex]

[tex]A=6126.9957[/tex]

[tex]A\approx 6126.996[/tex]

Therefore, the balance after one year is $6126.996.

Work Shown:

There are,

This means there are 3*4*2*2 = 12*4 = 48 different coffees. We'll use this value later, so let A = 48.

There are 6 bagel options. Also, there are 3 choices in terms of if you order the bagel plain, with butter, or with cream cheese. This leads to 6*3 = 18 different ways to order a bagel. Let B = 18.

Multiply the values of A and B to get the final answer

A*B = 48*18 = 864

There are 864 ways to order a coffee and bagel at this restaurant.

--------------

If you're curious why you multiply the values out, consider this smaller example.

Let's say you had 3 choices of coffee and 2 choices for a bagel. Form a table with 3 rows and 2 columns. Place the different coffee choices along the left to form each row. Along the top, we'll have the two different bagel choices (one for each column).

This 3 by 2 table leads to 3*2 = 6 individual table cells inside. Each cell in the table represents a coffee+bagel combo. This idea is applied to the section above, but we have a lot more options.
