The formula for the volume of a box (assuming that it is in the shape of a cube) is <u>V=B^3</u>.
12=B^3
Now, do the cube root of 12 to find each dimension, all dimensions will be equal as it is a cube.
B= about 2.29 (when doing on a calculator keep full answer and do not round)
Now to find the volume of box B, multiply each dimension by 5
5(2.29...) times 5(2.29...) times 5(2.29...)
=1,500 m^3
Hope this helps!
A
x=75°
B
We know that ∠EFG=∠ABF because they are corresponding angles.
We also know that ∠x+∠ABF=180, because angles along a straight line always equal 180:
x+105=180
x=75°
♥ Solve:
(Arjun) 40*30=1200
(Dalia) 55*30=1650
Now subtract
1650-1200=450.
That means that Dalia will type 450 minutes more.
Final answer: 450
(74 + 78 + 70 + x) / 4 = 80
Divide each number by 4.
18.5 + 19.5 + 17.5 + x = 80
Add the numbers you know so far.
18.5 + 19.5 + 17.5 = 55.5
You need 24.5.
Now, since we divided all the others by 4, we have to multiply 24.5 by 4 to see what the exam score would be.
24.5 * 4 = 98.
To get an average of 80%, the student would need to get a 98 on their fourth exam.
F(29) fits the 3rd set, so replace x with 29 and solve.
2(29-20)+ 30 = 18+30 = 48
The answer is 48
