Answer:

Hope this helps!^^

Step-by-step explanation:

1. 4^5/4^2

Apply exponent rule x^a/x^b=x^a-b

4^5-2

64

2. 8^-2

apply exponent rule a^-b =1/a^b

1/8^2

1/64

3. 19a(2y)^3(y)^0 y=3 a=2

First, lets complete the inside parenthesis

2*3=6

so
19a(6)^3(3)^0

19*2(6)^3(3)^0

8208

Answer:

1. 64

2. 1/64

3. 8208

Step-by-step explanation:

1.

4^5 = 1024

4^2 = 16

1024/16 = 64

2.

8^-2 = 8^(-1)x2

1/8^2 = 1/64

3.

19(2)x (2(3))^3(3)^0

38x6^3x1

38x216x1

=8208

Answer: Mario can (E) feed 12 friends with four pizzas.

Step-by-step explanation:

There are 4 pizzas, you'll need to find out how many 2/6 can fit into four pizzas which one of them equals 6/6. You know that 2/6 pizzas for each friend, so you can count how many slices of pizzas are there by two.

Answer:

[tex]\displaystyle {y^4}[/tex]

Step-by-step explanation:

The GCF of a set of numbers is the biggest divider that will divide all the numbers without leaving a remainder
As an example, the GCF of 4, 8 and 20 is 4, for 3, 4 and 5 it is 1 since there is no common factor

[tex]\textrm {We have the three numbers as }[/tex] [tex]y^4, y^5 \;and\; y^{10}[/tex]

Which of these numbers will divide into each of these without leaving a remainder?

[tex]\mathrm{The \:exponent\:rule}:\quad \dfrac{x^a}{x^b}=x^{a-b}[/tex]

This means the smallest exponent value [tex]y^4[/tex] will be the GCF because
[tex]\dfrac{y^4}{y^4} = 1\\\\\dfrac{y^5}{y^4} = y^{5-4}} = y^1\\\\\dfrac{y^10}{y^4} = y^{10-4}} = y^6\\\\\\[/tex]

So the general rule for finding the GCF of [tex]y^a, y^b \;and\; y^c is\\\\\mathrm {\;Choose\; the\; one \;with \;the \;lowest \;exponent \;value \;among \;exponents\; a, \;b \;and\; c}[/tex]

she forgot y and put x in the wrong spot

9.8

Step-by-step explanation:

becaus 2.5 +1 equals 7.8 +2 equals 9.8

Answer:

n each scaled copy, the sides are a certain number of times as long as the corresponding sides in the original. We call this number the scale factor. The size of the scale factor affects the size of the copy. A scale factor greater than 1 makes a copy that is larger than the original.

Junior says the product of 25 x 10 is 250.  Junior's answer is correct.

If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.

Given problem is;

25 × 10 = ?

Since, 1 × 10 = 10

2 × 10 = 20,

3 × 10 = 30,

4 × 10 = 40

When we observe this sequence,

It is found that, when we multiply a number by 10 we obtain the resultant number by putting 0 in the ones place of the given number.

That is,

25 × 10 = 250

Therefore, Junior's answer is correct.

Answer:

9,950

Step-by-step explanation:

First simplify the problem

1 x 10^4 would equal 1 x 10,000 so that would be 10,000 than,

5 x 10^1 would equal 5 x 10 so that would be 50 now,

10,000 - 50 = 9,950

And whenever your doing 10 to the power of anything just put a 1 and the number of zeros the power of is

Example: 10^9 = 1,000,000,000 or 10^3 = 1,000

This rule does not apply to numbers other than 10

Hope this helps <3

Answer:

10000 - 500= 9500

Step-by-step explanation:

so 10 exponent 4 is the same as 10000 and 10 exponent 1 is hundred 5×100= 500. so basically it's just 10000-500 which is 9500

Step-by-step explanation:

To find the total cost we need to know whats fixed, and what's variable (changing)

Fixed: $14 handbag

Variable: $0.50 / earring

Set up your polynomial, rule of thumb, all variables get multiplied by x

Total cost = x($0.50/earring) + $14 handbag

Substitute 0,5,10, and 15 for x and see which one matches the answer choices

Step-by-step explanation:

Let w = the width

Let 2w + 4 = the length

Let 7w-3 = the perimeter

P = 2l + 2w

7w-3 = 2w + 2(2w+4)

7w-3 = 2w + 4w + 8

w = 11

length = 2w + 4 = 2(11) + 4

length = 26

P = 7(11) -3 = 77 - 3

Perimeter = 74

Answer:Let w = the width

Let 2w + 4 = the length

Let 7w-3 = the perimeter

P = 2l + 2w

7w-3 = 2w + 2(2w+4)

w = 11

length = 2w + 4 = 2(11) + 4

length = 26

P = 7(11) -3 = 77 - 3

Answer:

The work that Ryan did to find the greatest common factor of 48 and 72 has no error, and Ryan found the least common multiple.

What is GCF (the greatest common factor)?

GCF or greatest common factor is the common number that all the term has in a group of terms.

The work that Ryan did to find the greatest common factor of 48 and 72 is shown below.

Prime factorization of 48: 2,2,2,2,3

Prime factorization of 72: 2,2,2,3,3

The greatest common factor is 2 ' 2 ' 2 ' 2 ' 3 ' 3

Here, the greatest common factor found is 2 ' 2 ' 2 ' 2 ' 3 ' 3 which is,

The number 144 is divisible by 48 and 72 in 3 times and 2 times respectively.

Thus, the work that Ryan did to find the greatest common factor of 48 and 72 has no error, and Ryan found the least common multiple.
