Hopefully someone can help you because I can’t do math either
Answer:
Volume of a cube with side length 1/3 of a meter = 1/27m^3
Step-by-step explanation:
Let
1 meter = m
V = s^3
Where,
V= volume of a cube
s= side length
s = 1/3 of a meter
= 1/3 × m
= 1/3m
V = s^3
= 1/3^3
= 1/3m * 1/3m * 1/3m
V = 1/27m^3
Volume of a cube with side length 1/3 of a meter = 1/27m^3
300 = 5t + 150
150 = 5t
30 = t
1990+ 30 = 2020
Answer:
x=12 ADB= 56 BDC= 54
Step-by-step explanation:
ADB and BDC are complementary, so they add up to 90 degrees. In other words ADB+BDC= 90 So I can input my knowns into the equation
(3x+10) + (4x-4) = 90
I combined like terms to give me 7x+6=90
Then I subtract 6 from both sides giving me 7x=84
Last I divide 7 on both sides. x=12
Then I input the x (12) into the equation and solve it from there
3(12)+10 and 4(12)-4
3(12)+10=56
4(12)-4=54
. . . I think. Hope this helps!
