Answer:
80 : 100: 40: 140
Step-by-step explanation:
The four angles of a quadrilateral add to 360 degrees.
Ratio
4 : 5 : 2: 7
Multiply each by x
4x: 5x : 2x : 7x This total is 360 degrees
4x+5x + 2x+7x =360
18x = 360
Divide each side by 18
18x/18 = 360/18
x =20
The angles are
4x: 5x : 2x : 7x
4(20): 5(20) : 2(20) : 7(20)
80 : 100: 40: 140
Answer: your answer will be 22.
Step-by-step explanation:
3t+1
3(7)+1
21+1
22
I think it’s C because the base is 180 degrees so C would be the best response
Step-by-step answer:
This is a problem involving subtraction of fractions.
To solve the problem, we find out the increase of the fraction of container and equate it to the amount of water added. Then we find the amount of water contained in the whole container (fraction = 1)
7 gallons = 4/5 - 3/10 = 8/10 - 3/10 =5/10 = 1/2 container
therefore, multiply by two on both sides,
14 gallons = 1 container
So container can hold 14 gallons.
Answer:
m=12
Step-by-step explanation:
8m=4m+48 subtract 4m from both sides
4m=48 divide both sides by 4 to get m alone
m=12
