Answer:
The answer is option 3.
Step-by-step explanation:
First we have to find the area of both rectangle and triangle :
Rectangle,
![area = base \times height](https://tex.z-dn.net/?f=area%20%3D%20base%20%5Ctimes%20height)
Let base = 9,
Let height = 3,
![area = 9 \times 3 \\ area = 27 \: {m}^{2}](https://tex.z-dn.net/?f=area%20%3D%209%20%5Ctimes%203%20%5C%5C%20area%20%3D%2027%20%5C%3A%20%20%7Bm%7D%5E%7B2%7D%20)
Triangle,
![area = \frac{1}{2} \times base \times height](https://tex.z-dn.net/?f=area%20%3D%20%20%5Cfrac%7B1%7D%7B2%7D%20%20%5Ctimes%20base%20%5Ctimes%20height)
Let base = 3,
Let height = 3,
![area = \frac{1}{2} \times 3 \times 3 \\ area = \frac{1}{2} \times 9 \\ area = \frac{9}{2} \\ area = 4.5 \: {m}^{2}](https://tex.z-dn.net/?f=area%20%3D%20%20%5Cfrac%7B1%7D%7B2%7D%20%20%5Ctimes%203%20%5Ctimes%203%20%5C%5C%20area%20%3D%20%20%5Cfrac%7B1%7D%7B2%7D%20%20%5Ctimes%209%20%5C%5C%20area%20%3D%20%20%5Cfrac%7B9%7D%7B2%7D%20%20%5C%5C%20area%20%3D%204.5%20%5C%3A%20%20%7Bm%7D%5E%7B2%7D%20)
Lastly, in order to find the shaded region you have to substract the area of triangle from the area of rectangle :
![area = 27 - 4.5 \\ area = 22.5 \: {m}^{2}](https://tex.z-dn.net/?f=area%20%3D%2027%20-%204.5%20%5C%5C%20area%20%3D%2022.5%20%5C%3A%20%20%7Bm%7D%5E%7B2%7D%20)
Answer:
Properties of operations help a lot in solving problems related to integers and rational numbers.
<u>Step-by-step explanation:</u>
There are four properties of operations in math. These properties are applicable in case of addition and multipication but not in case of division and subtraction.
These properties are used to solve problems involving rational numbers as well as integers.These properties are associative,commutative, distributive and identity.
commutative property is A+B=B+A
⇒5+4=4+5
and A*B=B*A
⇒5*4=4*5
associative property ( 32+14)+7= 32+(14+7)
( 8*9)*7= 8*(9*7)
Identity property is 35+0= 35
1*58=58
distributive property is 15*21
⇒ 15*(20+1)
⇒15*20+15*1
15*21
⇒ 15*(22-1)
⇒15*22-15*1
Answer: 6% of profit
Step-by-step explanation:
Find the % of profit
179 500 / 190 270 ≈ 0,94 = 94 %
100% - 94% = 6%
Answer:
120 gallons per hour.
Step-by-step explanation:
Between 1:30 P.M. and 1:50 P.M., 40 gallons of water leaked into a boat.
We know, the (1: 50 P.M. - 1: 30 P.M.) = 20 minutes.
So, the time span is of 20 minutes and the amount of water leaked into is 40 gallons.
Therefore, the amount of water that will leak into the boat in 60 minutes is
gallons.
So, the rate in gallons per hour of the leaking water is 120 gallons per hour. (Answer)
