1. 4^5/4^2

2. 8^-2

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

Answers

Answer 1

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 2

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:

[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]

Greg has
3 rows of stamps with 10 stamps in
each row. Greg says there are a total of
35 stamps. Use what you have learned
about multiples of 10 to explain why
Greg is incorrect.

Answers

Answer:

All multiples of 10 end with 0 only. So 35 must be wrong as it ends with 5. Therefore, Greg is incorrect.

It could not end in 5 and only in 0

Find the slope of the line that has a y intercept of 4 and passes through the point (-3, 1)

Answers

Answer: m = 1 (m is slope)

Step-by-step explanation:

1. y-int is coordinate, so it is (0,4)

2. with (0,4), we can now use (-3,1):
           4 - 1 = 3 and with the x, it is 0 + 3 = 3
                    So, it is 3/3 = 1, so the slope is 1



Answer:

Line L1 : Passes thro' (3,3)

y-intercept = 4 ===> (0,4)

Slope = (4 - 3)/(0 - 3) = 1/-3

Slope of L1 = -1/3.

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

Prime factorization of 48: 2x2x2x2x3
Prime factorization of 72: 2x2x2x3x3

The greatest common factor is 2'2'2'3x3

What is Ryan's error?

(A) Ryan did not add the common prime factors to get the greatest common factor
(B) Ryan did not list all the factors in the prime factorization of 48
(C) Ryan did not list all the factors in the prime factorization of 72
(D) Ryan did not include only common prime factors in the greatest common factor

Answers

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.

The answer is A ryan did not add the common prime factors

What would be the equation (using x) to solve "What are the dimensions of a rectangle whose length is 4 more than twice the width and whose perimeter is 3 less than 7 times the width?"

Answers

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)

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

w = 11

A rectangle has a length of 8 and width of 12. A scale copy was made with a width of 24. What is the area of the new rectangle?

Answers

Answer:

192 feet^2

Step-by-step explanation:

Length X Width = area

Answer:

The area of the new rectangle is 384 square units.

Step-by-step explanation:

For the original rectangle, the length is 8, and the width is 12. For the scale copy, the width is 24 (12 × 2), so the length will be 16 (8 × 2). Multiplying 24 by 16, we obtain 384 as the area of the new rectangle.
