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:

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.

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.

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]

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

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

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.
