When we multiply powers with the same base, we add the powers together. This will give us:

[tex]\frac{3^8*3^4}{3^2 * 3^8} \\\frac{3^{12} }{3^{10}}\\[/tex]

When we divide the fractions with the same base then we subtract the exponents:

3^12 / 3^10 = 3^12-10 = 3^2

If the perimeter of a regular pentagon can be expressed as 10s - 20, determine the length of each side.

50 s - 100
5 s - 10
s - 2
2 s - 4

Answers

Answer:

2 s - 4

Step-by-step explanation:

A Regular pentagon means that it has 5 evenly lengthen sides. In other words, the shape with 5 sides has lengths are equal to each other.  

Because the total perimeter as mentioned of the pentagon is 10s - 20,  

dividing it by 5 should find the length of each side!

Equation: (10s - 20) / 5

Once you finish dividing each digit inside the bracket you are done!

= 2s - 4

So that leaves us with 2s-4

Answer:

2 s - 4

Suppose Enrique has two building blocks. The area of one face of one of the blocks is 4 square centimeters and the area of the face of the other block is 100 square centimeters. What is the scale factor from the smaller block to the larger​ block?

Answers

Answer:

I think the larger block has a scale 25 times bigger than the smaller block since 100 divided by 4 equals 25

Please tell me if I'm wrong

I hope this helps

:D

Answer:

The Scale factor is 5.  

Step-by-step explanation:  

Because the area has cm^2  to find the scale factor you find the number it takes to get from one area to the next and take the square root.

4X = 100

X = 100/4

X = 25 (Take the sqrt because of area)

X = sqrt(25)

X = 5

The Scale factor is 5.

ΔABC is an isosceles triangle with AB = AC, D is the midpoint of BC and
AD is joined. Prove that ΔABD ≅ ΔACD.
I kinda have a problem with triangles and congruency....little help please ?

Answers

Step-by-step explanation:

Okay, so the triangle would look something like this:

see the image attached

Since AB=AC, which is given; <ABD = <ACD, because they are the angles opposite from the congruent sides of the isosceles triangle; and <ADB=<ADC, as AD is the bisector*; ΔABD ≅ ΔACD using SAA/AAS (side-angle-angle) congruencey.

*If the bisector of an angle in a triangle meets the opposite side at its midpoint, then the triangle is isosceles, and vice versa

After sales tax, A $96 watch costs $101.28. what is the sales tax percentage?

Answers

Answer:

i think it's 5.5 percent

Answer: The answer is 5.5% sales tax percentage

Step-by-step explanation:

First, subtract the total amount by the original amount

$101.28-$96= 5.28

Next, you would divide 5.28 by 96

5.28/96 = 0.055

The final part in which to get the answer is to multiply 0.055 with 100%

0.05·100= 5.5%

Regina is buying a new car. She sees two advertisements in the paper for the same car at two different prices from two different dealerships. Both dealers are offering a simple-interest loan for the price of the car.
