Answers

Answer 1

Answer:

D

Step-by-step explanation:

Following Pythagorean Theorom, we know a^2 + b^2 = c^2. We know b and c.  a^2 + 5^2 = 13^2.

a^2 + 25 = 169

a^2 = 144

a = √144

a = 12

So, the answer is 12, which means we pick D

Safety standards require a pool to add 3 chlorine tablets to every 2,000 gallons of water. Today, the lifeguards at Park Pool added 8 chlorine tablets to their pool's 10,000 gallons of water.

How does Park Pool's chlorine compare to the safety standards?
Choose 1 answer:

A
Park Pool has more chlorine than the safety standards require.

B
Park Pool has less chlorine than the safety standards require.

C
Park Pool has the right amount of chlorine.

Answers

Answer:

B

Step-by-step explanation:

The requirement is 3 chlorine tablets per every 2,000 galloons of water.

The lifeguards added 8 chlorine tablets for 10,000 galloons of water.

To get from 3 tablets to 8 tablets, we multiply by 8/3.

By multiplying 2,000 galloons of water by 8/3, we acquire approximately 5,333 galloons of water.

Since 5,333 is less than 10,000, the Park Pool has less chlorine than the safety standards require.

Hey there!

The correct answer is B

If they are supposed to add 3 for every 2000, that means they should have 6 for every 4000, and 9 for every 6000, and 12 for every 8000. This means they have less.

Hope it helps and have a great day!

Answer:

2d = 58 (If you are just finding d then d = 29)

Step-by-step explanation:

69 + 53 = 122

180 - 122 = 58

Answer:

29

Step-by-step explanation:

The total degree of a triangle is 180 so

(69 + 53) + 2d= 180

122 + 2d= 180

2d= 180-122

2d= 58

Divide both side by 2

which 29

BUT

i dont really understand if the 2 was the multiple or it just "2d"

in that case "2d" would be 58.
