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]

Higher Order Thinking: Junior says the
product of 25 x 10 is 250. How can you
use patterns to check Junior's answer?
Junior says the product of 25 x 10 is 250. Junior's answer is correct.
What is the fundamental principle of multiplication?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.

Please Help!! Grade 7 Math!! K12!!
Answer:
See below
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

Please help ASAP! (1 x 10^4) - (5 x 10^1)
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

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?"
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
length = 2w + 4 = 2(11) + 4
length = 26
P = 7(11) -3 = 77 - 3
Perimeter = 74

What is the length of bottom side of the scaled copy?
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.

Step-by-step explanation:
Describe how to evaluate an expression that contains variables. Be specific.
Answer:
To evaluate an algebraic expression, you have to substitute a number for each variable and perform the arithmetic operations. In the example above, the variable x is equal to 6 since 6 + 6 = 12. If we know the value of our variables, we can replace the variables with their values and then evaluate the expression.
Step-by-step explanation:
Answer:
You must substitute a number for each variable and carry out the arithmetic operations in order to evaluate an algebraic expression.
Step-by-step explanation:
To determine the value of a variable expression: Replace the values for the variables in step 1.

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
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.
