What is the greatest common factor of 8x and 22xy?
RideAnS [48]

The greatest common factor of 8x and 22yx is 2x.

I got this answer by factoring out 8 and 22:


8: 1,2,4,8

22: 1,2,11,22


Their greatest common factor was 2 and they both have x.


Your answer is 2x.

What is the solution set for<img src="https://tex.z-dn.net/?f=%20-%204%20%5Ctimes%20%20%2B%2010%20%5Cgeqslant%205%28x%20%2B%2011
Alexus [3.1K]

Answer

The solution set to this inequality equation is

x ≤ -5

Explanation

We are asked to find the solution set for

-4x + 10 ≥ 5 (x + 11)

-4x + 10 ≥ 5x + 55

-4x - 5x ≥ 55 - 10

-9x ≥ 45

Divide both sides by -9 (Note that dividing both sides of an inequality equation by -9 will reverse the inequality sign)

(-9x/-9) ≤ (45/-9)

x ≤ -5

Hope this Helps!!!

URGENT PLEASE ANSWER To find the distance across a river, a surveyor chooses points A and B on one side of the river. She then c
Rus_ich [418]

Answer:

The distance between A and C = 127.4

Step-by-step explanation:

* We have 3 different points A , B , C lets consider them as

 a vertices of a triangle ABC

- AB = 100

- m∠A = 47°

- m∠B = 82°

* To find the distance AC we can use the sin Rule

- In any triangle the ratio between the length of each side

 to the measure of each opposite angle are equal

- In Δ ABC ⇒ AB/sinC = BC/sinA = AC/sinB

* Lets do it to find the distance between A and C

∵ m∠A = 47° and m∠B = 82°

∵ The sum of the interior angles in any triangle is 180°

∴ m∠C = 180 - (47 + 82) = 180 - 129 = 51°

∵ AC/sin(82) = 100/sin(51)

∴ AC = 100 × sin(82) ÷ sin(51) = 127.423691

* AC = 127.4

A local rectangular shaped pool used by lap swimmers has dimensions 25 yd by 30 yd and is 5.1 feet deep. Find the cost for filli
Lelu [443]

Answer:

the cost of filling the pool is $386.3

Step-by-step explanation:

Given;

dimension of the rectangular pool, = 25 yd by 30 yd by 5.1 ft

covert the given dimensions to feet;

1 yd = 3 ft

25 yd = 25 x 3 ft = 75 ft

30 yd = 30 x 3 ft = 90 ft

The volume of the rectangular pool in cubic feet (ft³);

Volume = 75 ft  x 90 ft  x 5.1 ft

Volume = 34,425 ft³

Convert the volume to gallons;

1 ft³ = 7.481 gallons

10,125 ft³ = 34,425 x 7.481 gallons

               = 257,533.425 gallons

The cost per a 1000 gallons is $1.50, then cost of the 257,533.425 gallons is calculated as;

cost = \frac{\$ 1.50}{1000 \ gallons} \times 257,533.425 \ gallons = \$ 386.3

Therefore, the cost of filling the pool is $386.3
