Carlos paid an electrician x dollars per hour for a 4-hour job and $85 for parts. The total charge was $305. Which equation can be used to determine how much the electrician charged per hour?

Answer:

There are approximately 343 families in the sample.

Step-by-step explanation:

xth percentile:

A measure is said to be in the xth percentile if it is greater than x% of the measures.

Twenty-four of the families in the sample turned on the television for 16 hours or less for the week. The 7th percentile of the data is 16 hours.

This means that 7% of the sample size n is 24. So

[tex]0.07n = 24[/tex]

[tex]n = \frac{24}{0.07}[/tex]

[tex]n = 342.86[/tex]

Rounding up, there are approximately 343 families in the sample.

Answer:

400 cm²

Step-by-step explanation:

Triangles: 1/2x15x8=60 (two of those)

Base: 8x7=56

Back: 15x7=105

Sloped side: 7x17=119

60+60+56+105+119=400 cm²

Answer: its H

Answer:

X= 2/5 y=-2

Step-by-step explanation:

5x + 2y = -2

3x - 5y = 11.2

Using the elimination method

Multiply equation 1 by 3

Multiply equation 2 by 5

15x + 6y = -6

15x - 25y = 56

Subtrat  3 from 4

-31y= 62

Divide both sides by -31

y= -2

To arrive at x, substitute y= -2 in equation 1

5x + 2y = -2

5x + 2(-2)= -2

5x -4 = -2

Collect like terms

5x= -2+4

5x= 2

Divide both sides by 5

x= 2/5

Is these type of questions the decimal, (the little dot between the numbers) is really important.

        2.094<=>2.702    In both of the equations there is a 2, and then the decimal, what numbers are next? 7, and 0. Which one of those it bigger?  7!!!!

so 2.094<2.702

Answer:

t=-4

Step-by-step explanation:

48/-12

Answer:

48=-12t

We simplify the equation to the form, which is simple to understand  

48=-12t

We move all terms containing t to the left and all other terms to the right.  

+12t=-48

We simplify left and right side of the equation.  

+12t=-48

We divide both sides of the equation by 012 to get t.  

t=-4

Answer:

Step-by-step explanation:

Math is in our everyday lives. We calculate and use math in our daily lives without knowing it. By learning math, we build on useful knowledge that will help us have a better future. For example, learning how to pay taxes acquire math. Grocery shopping needs you to find the cost of the product you’re buying. When we learn math, we gain knowledge and we can pass that knowledge to our future generations so more and more people can use it to find better jobs, make your life easier, and so much more. Therefore, that is why it is important for students to learn about math.

Step-by-step explanation:

Sine is opposite divided by the hypotenuse.

sin(30) = 9/y

1/2 = 9/y

y = 18

Cosine is adjacent divided by the hypotenuse

cos(30) = x/18

[tex]\frac{\sqrt{3} }{2}=x/18\\x=9\sqrt{3}=15.6[/tex]

Answer: You are correct. The answer is choice A. Nice work.

Explanation:

Assuming Ramon did his steps correctly, ending up with 53 = 477 means that the original equation doesn't have any solutions.

Consider an example such as x+5 = x+6

We can subtract x from both sides to end up with 5 = 6, but that's a false statement. So no value of x can be plugged into x+5 = x+6 to lead to a solution. This idea applies to Ramon's original equation. The equation 53 = 477 is a contradiction (the left side contradicts the right side since the numbers don't match).

Answer: 9% sales tax

Step-by-step explanation: 40.33-37=3.33

so, now we got to divide 3.33 by 37 (3.33/37) and that = 0.09. Now we got to do 0.09x100 and you get 9%. So basically, subtract, divide, and multiply by 100

Answer:

You can always find the 'nth term' by using this formula: nth term = dn + (a - d) Where d is the difference between the terms, a is the first term and n is the term number.
