Answer:
4.08 inches.
Step-by-step explanation:
A cube has six sides, and each of the sides has area of , where is the length of the edge of the cube.
Thus the total surface area of the cube is
Now we are told that this surface area is 100 square inches, therefore , and now we can solve for :

Step-by-step explanation: 6 26 18 13
The two outside angles are congruent. The two inside angles are supplemental thus they are equal. The last two angles the high one and the lower one must sum to 180° in their respective triangles so they are equal since their similar angles are equal.
find x
4 is to x as 5 is to 7.5
4/x = 5/7.5 solve for x
4 × 7.5 / 5 = x
30 / 5 = x
6 = x
Answer:
12
Step-by-step explanation:
You set up cross multiplication 3/4 x 9/x, you go 4x9=36 divided by 3 equals 12
First equation: 3x+4y-12=0. Solving for 4y, we get 4y = -3x + 12, from which
y = (-3/4)x - 3. The slope is -3/4 and the y-int. is -3.
Second equation: 2x + y = 1. y = -2x + 1. The slope is -2 and the y-int. is 1.
