How can you rewrite a^7 using exponent rules?

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

could be wrong but, go for II

Answer:

II

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.

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:

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:

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: 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

Step-by-step explanation:

9% of 20,000 is 1,800. So, if you keep subtracting 1,800 from 20,000, it will take 4 times until you get to 12,800, which is as close as you can get to 13,000 in this scenario.

Answer:

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:

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
