Answer: 450 minutes
Step-by-step explanation:
4 hours and 30 minutes equals 4.5 hours.
3+4.5=
7.5 hours
1 hour equals 60 minutes
Hence,
7.5*60=
450 minutes
Answer:
x=-3
Step-by-step explanation:
You need to move all the x values together, so minus 4x. Then move the +3 to the other side of the equals by minusing it to get -3.
5x+3=4x
x+3=0
x=-3
Answer:
x=6
Step-by-step explanation:
Since both have the same base,
5x-8 = 22
5x = 22+8
5x = 30
x= 30 ÷ 5
x= 6
Answer:
by using distributive property
4( 1 + 9 x) = 4.1 + 4.(9 x)
Step-by-step explanation:
<u>Step :- 1</u>
<u>Explanation :-</u>
The distributive property of multiplication states that when a number is multiplied by the sum of two numbers , the first number can be distributed to both of those numbers and multiplied by each of them separately, then adding the two products together for the same result as multiplying the first number by the sum.
a .(b+c) = a.b + a.c
Given 4 + 36 x = 4(1+9 x)
by using distributive property
4 .( 1+36 x ) = 4.1 + 4.(9 x)
= 4.1+4.9(x)
Answer:
97 cm²
Step-by-step explanation:
The complete question is attached.
The circle has a diameter of 12 m. The radius of the circle = diameter/2 = 12/2 = 6 cm.
The area of the circle = πr² = π × 6² = 113 cm²
To find the area of the shaded portion we have to find the area of sector and subtract it from the circle area.
The angle of the sector (θ) = 360 - 310 = 50°
![Area\ of\ the\ sector=\frac{\theta}{360} *\pi r^2=\frac{50}{350}*\pi*6^2=16\ cm^2](https://tex.z-dn.net/?f=Area%5C%20of%5C%20the%5C%20sector%3D%5Cfrac%7B%5Ctheta%7D%7B360%7D%20%2A%5Cpi%20r%5E2%3D%5Cfrac%7B50%7D%7B350%7D%2A%5Cpi%2A6%5E2%3D16%5C%20cm%5E2)
Area of shaded portion = Area of circle - Area of of sector = 113 - 16 = 97 cm²
