The set {126, 168, 189} has 21 as a common factor.
The set{154, 231} has 11 as a common factor.
Common factor:If a number m is completely divisible by number n. Then number n will be the one factor of number m.
(a). Given set of number is, {126, 168, 189}
Now check, 21 is a common factor or not.
[tex]\frac{126}{21}=6,\frac{168}{21}=8,\frac{189}{21}=9[/tex]
It is observed that all numbers are completely divisible by 21.
So that , 21 is common factor.
(b). Given set of number is, {154, 231}
[tex]\frac{154}{11}=14,\frac{231}{11}=21[/tex]
It is observed that all numbers are completely divisible by 11.

D is the second best answer. It is still incorrect. If you simply subtract the x's don't cancel. B and C are both incorrect because you're not doing anything to adjust the ys.
the answer is A. If you simply add, the x's will cancel and you will be left with 11y = 22

The measure of angle D is 50⁰, the measure of angle E is 80⁰, and the measure of angle F is 10x . What is the value of x ?
By the interior angle theorem of triangles, the value of x is 5°.
What is a triangle?A triangle is a three-sided closed-plane figure formed by joining three noncolinear points. Based on the side property triangles are of three types they are Equilateral triangle, Scalene triangle, and Isosceles triangle.
We know the sum of the interior angles in a triangle is 180°.
Given, In a triangle DEF the measure of angle D is 50⁰, the measure of angle E is 80⁰, and the measure of angle F is 10x .
Therefore, m∠D + m∠E + m∠F = 180°.
50° + 80° + 10x = 180°.
10x = 180° - 130°.
10x = 50°.
x = 5°.
So, The value of x is 5°.

The value of a car decreases by 5% each year. Sophie bought a car two years ago for £10000. Work out the value now.
Given:
The value of car before two years = £10000
The value of the car decreases by 5% each year.
To find:
The present value of the car.
Solution:
The exponential decay model for present value is
[tex]y=a\left(1-\dfrac{r}{100}\right)^t[/tex]
Where, a is the initial value, r is the rate of decay and t is time in years.
Putting P=10000, r=5 and t 2, we get
[tex]y=10000\left(1-\dfrac{5}{100}\right)^2[/tex]
[tex]y=10000\left(1-0.05\right)^2[/tex]
[tex]y=10000\left(0.95\right)^2[/tex]
On further simplification, we get
[tex]y=10000(0.95)(0.95)[/tex]
[tex]y=9025[/tex]
Therefore, the present value of the car is £9025.
_________________________ 6Harry is planning a holiday for 4 people for 7 days. Here are the costs for the holiday for each person. Travel£150 Hotel£50 for each day Spending money£250 Work out the total cost of the holiday for 4 people for 7 days.
Answer: $3,000
Step-by-step explanation:
The cost for a single person is:
Travel £150
Hotel £50 for each day
Spending money £250
Hotel is the only one that changes per the number of days so the total cost for a single person for 7 days is:
= 150 + (50 * 7) + 250
= 150 + 350 + 250
= $750
There are 4 people so the total cost will be:
= 750 * 4 people
= $3,000

The bases of a trapezoid have lengths 10 and 18. If the height of the trapezoid is 6, what is the area of the trapezoid
Answer:
84
Step-by-step explanation:
The bases of a trapezoid have lengths 10 and 18. If the height of the trapezoid is 6, what is the area of the trapezoid
The area of a trapezoid is given as:
1/2(b1 + b) × h
Where:
b1 = Base 1 = 10
b2= Base 2 = 18
h = Height = 6
Therefore, the area of a trapezoid =
1/2 (10 + 18) × 6
= 28/2 × 6
= 84
Therefore, the area of the trapezoid = 84
(Easy) What is the next term in the sequence: 2, -2/3, 2/9, -2/27
Answer:
[tex]\frac{2}{81}[/tex]
Step-by-step explanation:
There is a common ratio between consecutive terms in the sequence
r = [tex]\frac{-\frac{2}{3} }{2}[/tex] = [tex]\frac{\frac{2}{9} }{-\frac{2}{3} }[/tex] = [tex]\frac{-\frac{2}{27} }{\frac{2}{9} }[/tex] = - [tex]\frac{1}{3}[/tex]
To find a term in the sequence multiply the previous term by - [tex]\frac{1}{3}[/tex] , then
a₅ = - [tex]\frac{1}{3}[/tex] × a₄ = - [tex]\frac{1}{3}[/tex] × - [tex]\frac{2}{27}[/tex] = [tex]\frac{2}{81}[/tex]

They are 20 blocks per mile in tara's city. Tara's walks 13 blocks. Her fitness tracker say he walk 0.71 mile. Show if her fitness tracker is accurate.
Answer:
Step-by-step explanation:
13 blocks × (1 mile)/(20 blocks) = 13/20 mile = 0.65 mile
Tracker is inaccurate
The fitness tracker is inaccurate.
What is a Ratio?A ratio indicates the number of times one number contains another.
Given that, there are 20 blocks per mile.
20 blocks = 1 mile
1 block = (1/20) mile
13 block = (13/20) mile
13 block = 0.65 mile
Therefore, Tara walks 0.65 miles, not 0.71 miles.
Hence, the fitness tracker is inaccurate.

The captains of the soccer team describe ordering identical T-shirts for the team. Bindi says the total cost is $192. Gina says the cost is 8t, where t is the number of T-Shirts. Which person tells how much each T-shirt costs? How do you know?
Answer:
Both of them.
Step-by-step explanation:
Gina says the cost is 8t, which means you can easily find out the cost of each t-shirt if you know the the total cost too. Bindi says the total cost was 192, which is completely useless on its own, but paired with Gina's info, you can get the answer. Divide 192 by 8, and you get the cost of each t-shirt.
