Answer:

406 meters squared

Step-by-step explanation:

14 times 5= 70 (Section 1)

21 times 16= 336 (Section 2)

(Combine Sections 1 and 2)

336 + 70= 406

Answer: 406m^2

Step-by-step explanation:

Area of a parallelogram: A=b*h

Area of a rectangle: A=l*w

Find these 2 separate areas and add them together.

Parallelogram:

Base: 21m

Height: 16m

----------------------------------------------------------------------------------------------

A=b*h\\A=(21m)(16m)\\A=336m^2

----------------------------------------------------------------------------------------------

Rectangle:

Length: 14m

Width: 5m

----------------------------------------------------------------------------------------------

A=l*w\\A=(14m)(5m)\\A=70m^2

-----------------------------------------------------------------------------------------------

Area of the composite figure: A_p+A_r=A_c_f\\336m^2+70m^2=A_c_f\\Area_c_f=406m^2

Help me!! A water tank is 1/8 full. The tank is 3/4 full when 42 gallons of water is added to the tank. How much can the water t
chubhunter [2.5K]

Answer(s):

1.) 56 gallons

2.) 7 gallons

3.) 28 gallons

Step-by-step explanation:

<u><em>Q1: How much water can the tank hold?</em></u>

Based on the question, we know that 3/4 of the tank equals 42 gallons. Divide 42 by the numerator, 3.

42/3 = 14

Now, multiply 14 by the denominator, 4.

14 x 4 = 56.

<em><u>So, the tank can hold 56 gallons.</u></em> [If you'd like to double check this answer, take the fraction 42/56 and simplify it to get 3/4.

<u><em>Q2: How much water was originally in the tank?</em></u>

We know that the tank's maximum capacity is 56 gallons. So, if it was 1/8 originally full, multiply 56 by 1/8. [Remember that 56 as a fraction can be written as 56/1]

1/8(56/1) = 7

<u><em>This means that the tank was originally 7 gallons full.</em></u> [If you'd like to double check this answer, take the fraction 1/8 and multiply the numerator and denominator by 7. This gets you 7/56, or 7 gallons out of the total capacity, 56 gallons.]

<u><em>Q3: How much water is in the tank when it is 1/2 full?</em></u>

Earlier, we found out that the maximum capacity of the tank is 56 gallons. To find out how many gallons it holds when its half full, divide 56 by 2.

56/2 = 28

<em><u>So, when the tank is 1/2 full, it contains 28 gallons.</u></em> [If you want to double check this answer, take  the fraction 28/56 and simplify it. When you do, you get 1/2.]
