what is the greatest common factor of the expression below?
22x^5 + 20x
Answers
Answer:
the answer is 2x
Step-by-step explanation:
The greatest common factor of the expression 22x^5 + 20x is 2x. Both the numerical values and the variable components are considered to determine this.
Explanation:To find the greatest common factor of the expression, we need to identify the highest number and the highest power of variable that evenly divides both terms. In the case of the expression 22x^5 + 20x, the numerical part of the greatest common factor can be found by examining 22 and 20. The greatest common factor of 22 and 20 is 2. Next we need to look at the variables in each term, in this case 'x'. The highest power of 'x' that will divide both 'x^5' and 'x' is 'x' itself.
So, combining these two elements, the greatest common factor of the expression is 2x.

According to one survey, 25% of high school
students reported that they would not get summer
jobs. Predict how many of the 948 students at
Mohawk High School will not get summer jobs.
Answers
Answer:
237
Step-by-step explanation:
25/100 = x/948, simplify to get 1/4 = x/948
cross multiply and get 948=4x
swap the sides and get 4x=948
divide both sides by 4 and get x=237
in conclusion 237 students won't get summer jobs.
About 237 students at Mohawk High School are predicted not to get summer jobs based on applying the survey percentage of 25% to the total student population of 948.
Explanation:To predict how many students at Mohawk High School will not get summer jobs, we use the percentage from the survey and apply it to the total number of students at the school. According to the survey, 25% of high school students reported that they would not get summer jobs. Mohawk High School has a total of 948 students.
To find the number of students who will not get summer jobs, we perform the following calculation:

Find the exact area of a triangle with two sides that measure 6 yd and 2 yd with an included
angle of 10°
Answers
Answer:
1 yd^2
Step-by-step explanation
A=1/2(2)(6)Sin(10)
Final answer:
The area of a triangle with sides of 6 yd and 2 yd and an included angle of 10° is approximately 1.0439 square yards.
Explanation:
To find the exact area of a triangle with two sides measuring 6 yd and 2 yd and an included angle of 10°, you can use the formula for the area of a triangle when two sides and the included angle are known: A = ½ ab × sin(C), where a and b are the sides and C is the included angle.
The calculation will be: A = ½ × 6 yd × 2 yd × sin(10°). Using a calculator with the sine function set to degrees, we find that sin(10°) ≈ 0.17365. Therefore, the area A is approximately: A = ½ × 6 yd × 2 yd × 0.17365 ≈ 1.0439 yd².
Thus, the exact area of the given triangle is approximately 1.0439 square yards.

Answers
In a mixed market economy, which typically combines elements of both market and government intervention, the BEST example is the government imposes a limit on the number of television sets that can be exported annually. Here option D is correct.
This scenario reflects a government intervention aimed at managing international trade and protecting domestic industries. By imposing export limits on television sets, the government can regulate the flow of goods, balance trade, and potentially safeguard local industries from excessive foreign competition.
This intervention allows for a controlled market environment while still allowing private enterprises to operate. Unlike the other options, this scenario demonstrates a strategic use of government intervention to achieve economic objectives without completely dominating the market or infringing on individual business operations.
It showcases a balance between free-market principles and government oversight, characteristic of a mixed market economy. Here option D is correct.

Samuel and Randi are placemat weavers. Samuel can weave 7 placemats in 8 hours. Randi can weave 5 placemats in 4 hours. How many placemats can they make in 5 days if they worked 8 hours each day?
Answers
Answer: 85 placemats
Step-by-step explanation:
Let’s split it into three parts: how much Samuel can weave, how much Randi can weave, and how much they can weave in total
Part 1: Samuel
First, let’s figure out how much Samuel can weave!
First, we know that Samuel can weave 7 placemats in 8 hours (1 day). So, if he weaved placemats for 5 days, then:
= 7 x 5
= 35
Therefore, Samuel weaved 35 placemats in 5 days if he worked 8 hours each day.
Part 2: Randi
We know that Randi makes 5 placemats in 4 hours, which is half, a day. But lets figure out how many placemats he can make it a day.
All we have to do is multiply by two.
= 5 x 2
= 10
So, we now know that he can make 10 placemats in a day. Now, let’s see how many placemats he can make in five days.
= 10 x 5
= 50
Therefore, Randi weaved 50 placemats in 5 days if he worked 8 hours each day.
Part 3: Adding Them
Now, we have 35 placemats from Samuel and 50 placements from Randi. So, we have to add them.
= 35 + 50
= 85
Therefore, Randi and Samuel can make 85 placemats in 5 days together if they work 8 hours each day.
Samuel and Randi can make a total of 85 placemats in 5 days.
Explanation:To find out how many placemats Samuel and Randi can make in 5 days, we need to calculate how many placemats each of them can make in one hour. Samuel can weave 7 placemats in 8 hours, so he can weave 7/8 placemats in one hour. Randi can weave 5 placemats in 4 hours, so she can weave 5/4 placemats in one hour. To find out how many placemats they can make in 5 days, we need to multiply their rates by the number of hours they work in 5 days. Samuel can make (7/8) * (8 * 5) = 35 placemats in 5 days. Randi can make (5/4) * (8 * 5) = 50 placemats in 5 days. Therefore, Samuel and Randi can make a total of 35 + 50 = 85 placemats in 5 days.

To find the value of [tex]\(x\)[/tex] in the given circle, we need to use the properties of the circle and the given information about the segments.
1. Given:
PM is a chord of the circle with center [tex]\(Q\)[/tex].
[tex]\(NL\)[/tex] is the perpendicular bisector of [tex]\(PM\)[/tex].
[tex]\(T\)[/tex] is the midpoint of [tex]\(PM\)[/tex], and [tex]\(T\)[/tex] lies on [tex]\(NL\)[/tex].
[tex]\(MT = 5x - 6\)[/tex] and [tex]\(TP = 2x + 9\)[/tex].
2. Key Properties:
Since [tex]\(T\)[/tex] is the midpoint of [tex]\(PM\)[/tex], we have [tex]\(PT = TM\)[/tex].
The perpendicular bisector of a chord passes through the center of the circle, so [tex]\(NL\)[/tex] passes through [tex]\(Q\)[/tex].
3. Equating the Segments:
Since [tex]\(T\)[/tex] is the midpoint of [tex]\(PM\)[/tex], we have:
[tex]\[ PT = TM. \][/tex]
Using the given expressions for [tex]\(MT\)[/tex] and [tex]\(TP\)[/tex]:
[tex]\[ MT = 5x - 6 \quad \text{and} \quad TP = 2x + 9. \][/tex]
Because [tex]\(T\)[/tex] is the midpoint, [tex]\(PT = TM\)[/tex].
Therefore, we have:
[tex]\[ PT = TM = 2x + 9. \][/tex]
Since [tex]\(MT = 5x - 6\)[/tex], and [tex]\(PT = TM\)[/tex], we have:
[tex]\[ 5x - 6 = 2x + 9. \][/tex]
4. Solving for [tex]\(x\)[/tex]:
[tex]\[ 5x - 6 = 2x + 9. \][/tex]
[tex]\[ 3x - 6 = 9. \][/tex]
[tex]\[ 3x = 15. \][/tex]
[tex]\[ x = 5. \][/tex]
9600 dollars is placed in an account with an annual interest rate of 5%. To the nearest year, how long will it take for the account value to reach 37800 dollars?
Answers
Answer: lt will take 28.09 years for the account value to reach $37800
Step-by-step explanation:
Hi, to answer this question we have to apply the compounded interest formula:
A = P (1 + r) t
Where:
A = Future value of investment (principal + interest)
P = Principal Amount
r = Annual Nominal Interest Rate (decimal form)
Replacing with the values given
37800= 9600 (1+0.05)^t
Solving for t (years)
37800/9600 = 1.05^t
3.9375 = 1.05^t
log 3.9375 = log 1.05^t
log 3.9375 = t (log 1.05)
log 3.9375/log 1.05 = t
t = 28.09 years
Noah scores n points in a basketball game.
a. What does 15 < n mean in the context of the basketball game?
Answers
Answer: Noah scores more than 15 points.
Step-by-step explanation:
Hi, to answer this question we have to analyze the inequality:
15 < n
Where n are the scored points on a basketball game.
< means greater than.
So, in the context of the basketball game, it means that Noah scored more than 15 points.
Feel free to ask for more if needed or if you did not understand something.
The correct interpretation of 15 < n in the context of the basketball game is that Noah scores more than 15 points.
The inequality 15 < n indicates that the number of points Noah scores, represented by n, is greater than 15. This means that the actual number of points Noah scores must be any number that is a increment above 15, but cannot be 15 itself. For example, if Noah scores 16 points, 17 points, or any number of points greater than 15, the inequality 15 < n would be satisfied. It is a mathematical way of stating that Noah's score exceeds 15 points.

Lindsay bought 3 shirts for $15 each. The sales tax in Indiana is 7%. What is the total cost of her purchase?
Answers
Answer:
$48.15
Step-by-step explanation:
To work this out you will first need to work out the cost of the shirts. You can do this by multiplying 15 by 3, which gives you 45. The next step is to work out the percentages, however there are two methods you can use. Method 1 is easier and involves directly calculating the total. While Method 2 is to use the traditional method of working out the percentage and then adding it to the price of the shirts.
1) Multiply 15 by 3.
[tex]15*3=45[/tex]
Method 1:
The first step for method 1 involves converting the percentage into a decimal. You can do this by dividing 7 by 100, which gives you 0.07. This is because percentages are out of 100. the next step is to add 1 to 0.07, which is 1.07. This is because we are increasing the amount by 7%. You would then multiply 45 by 1.07, which gives you $48.15.
1) Divide 7 by 100.
[tex]7/100=0.07[/tex]
2) Add 1 to 0.07.
[tex]0.07+1=1.07[/tex]
3) Multiply 45 by 1.07.
[tex]45*1.07=48.15[/tex]
Method 2:
The first step for the second method you would first need to divide the percentage of 7 by 100, which gives you 0.07. Then you would multiply that by the amount of 45, which gives you 3.15. Then you would add 3.15 to 45, which gives you $48.15
1) Divide 7 by 100.
[tex]7/100=0.07[/tex]
2) Multiply 0.07 by 45.
[tex]0.07*45=3.15[/tex]
3) Add 3.15 to 45.
[tex]3.14+45=48.15[/tex]
