The problem does not mention what level tanks A and B were filled to before the leak. I'll assume that the tanks were filled as the figure shows.

Part (a)

Initial volume of water of tank A is
20 cm * 36 cm * 40 cm = 28,800 cm^3

Initial volume of water in tank B is
30 cm * 36 cm * 9 cm = 9,720 cm^3

The total combined water in tanks A and B is
28,800 cm^3 + 9,720 cm^3 = 38,520 cm^3

Now the water is in tanks A and B.
The area of the base of the entire tank (A & B) is
50 cm * 36 cm = 1,800 cm^2.

The total volume of water in tanks A and B evenly (same height) distributed
into tanks A and B has a height
(38,520 cm^3)/(1,800 cm^2) = 21.4 cm

Part (b)

The volume of water in tank B, after the water in both tanks is at the same level, is
30 cm * 36 cm * 21.4 cm = 23,112 cm^3

Tanks B already contained 9,720 cm^3, so the amount of water that flowed from tank A to tank B was

23,112 cm^3 - 9,720 cm^3 = 13,392 cm^3

1 1/2 h = 90 min

(13,392 cm^3)/(90 min) = 148.8 cm^3/min

g A shopping center includes a grocery store and a drug store. One%E2%80%8B afternoon, a total of 200 people visited the shoppin
QveST [7]

Answer:

a) 179 people shopped at the grocery store or the drug store.

b) 21 people shopped at neither the grocery store nor the drug store

Step-by-step explanation:

I am going to treat these events as Venn sets.

I am going to say that:

Set A: Shopped at the grocery store

Set B: Shoped at the drug store.

121 shopped at the grocery store:

This means that A = 121

91 shopped at the drug store:

This means that B = 91

33 shopped at both businesses.

This means that A \cap B = 33

a) How many people shopped at the grocery store or the drug store?

This is

A \cup B = A + B - (A \cap B)

With the values given in the exercise.

A \cup B = A + B - (A \cap B) = 121 + 91 - 33 = 179

179 people shopped at the grocery store or the drug store.

b) How many people shopped at neither the grocery store nor the drug store?

179 of 200 shopped in at least one. So 200 - 179 = 21 shopped at neither.

21 people shopped at neither the grocery store nor the drug store

Help, I don’t know how to solve this.

Answer: Angles ABD and BAD (B)

Step-by-step explanation: Angles ABD BAD are not congruent angles, since they are the same angles.

Congruent angles are angles that both measure the same in degrees.

In this case, B is your correct answer since that answer has the same angle and not comparing any 2 angles, just the same one.

Hope This Helped, Have A Great Day!
