Answer:
V = 10.5 ft³
Step-by-step explanation:
Volume formula: length x width x height
We are given all 3, so all we have to do is multiply them all together, When we plug it into the calc, we should get 21/2 or 10.5 ft³ as our answer.
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:
6
Step-by-step explanation: You can set up the equation: = You square both sides to cancel out the squares which leaves you with = n - 4. Then you just solve as normal which ends you up with an answer of 6. You can check this by plugging 6 back into the equation and see that you end up with on both sides.
5(2x-6) + 20 = 10
10x - 30 + 20 = 10
10x-10 = 10
OR 10x = 20
so x = 2
