Explanation:
A cube is made up of equal length sides (s).
The volume of a cube is s x s x s.
Therefore, s=4 in this case (4x4x4=64).
A cube is made up of 6 squares, each with an area of s x s.
Therefore, the surface area of a cube is 6 x s x s = 6 x 4 x 4 = 96
Explanation:
If you divide both sides of the formula by M, then A = F/M
Explanation:
3451/7562=.4563
Explanation:
40 divided by .08 = 500
Explanation:
With each of the 4 shirts you can wear one of the 5 ties,
so the total number of combinations is 4 x 5 = 20
Explanation:
$4.20/4 = $1.05
$4.20 - $1.05 = $3.15
Explanation:
Divide both sides by 0.05.
Therefore, z= 1/0.05=20
Explanation:
If x = y,
then you can subsitute x for y in the 2nd equation - so 4(x-x)+7 =
4(0)+7=7
Explanation:
V=LxWxH
L (327) x W(15.3) x H(12.6) =
63,039 cubic feet
Explanation:
4 cubed is 4 x 4 x 4 = 64
Explanation:
93 is not a prime number since it is equal to 31 x 3.
If you add up the digits of a number and they are divisible by 3,
then the number is also divisible by 3.
Explanation:
-1 × 1.8 + 32 = 30.2
Explanation:
If 1/3 are on vacation, then 2/3 are not. Of those 2/3 not on vacation,
3/4 are NOT sick. Therefore 2/3 x 3/4 are in the office (not on vacation and not sick)
= (2x3)/(3x4)=6/12=1/2
Explanation:
If x + y + 15 = 30, then z+ 15 = 30 (substitute x + y = z)
which means that z = 15. If z = 15, then 40 - z = 40 - 15 = 25
Explanation:
(10×3) = 30
12+18 = 30
Explanation:
You need to subtract the money that she spent ($500) from the original money that she had (Z).
Explanation:
There are 12 cards in total. Therefore,
the probability of picking a hockey card is 6/12 or 1/2.
Explanation:
-9x, -6x, -3x, x, 5x
Since we know x is positive, the terms can be placed in order from smallest to largest.
By definition the median is the middle term in this list
Explanation:
There are 18 total pieces of candy and 3 lollipops.
Therefore, the probability of picking one lollipop is 3/18 which simplifies to 1/6
Explanation:
There are a total of 28 cards – 7 red; 21 green.
Therefore the probability of selecting an red card is: 7/28 = 1/4)
Explanation:
After distributing the 2, the equation is equivalent to 6a -1 = 2a + 2.
Simplifying, 4a = 3, so a = 3/4
Explanation:
The goal here is to isolate the variable to one side with the constants on the other.
By subtracting 5x from both sides, you can rewrite the equation as: -5 = x + 8.
This simplifies to x = -13 when 8 is subtracted from both sides
Explanation:
The diagonal forms a right triangle with the width and the length acting as legs.
Using the Pythagorean theorem, the length of the triangle will be √25^2 – 15^2 =
√400 = 20, and the area will be 20 x 15 = 300
Explanation:
If the number of sophomores in the room is x, then the number of freshman is 7x.
The total number of people in the room is 7x + x = 8x. The number of people in the
room (8x) must be a multiple of 8.)
Explanation:
The sum of the exterior angles of any polygon is 360°, so the exterior angle at vertex Z is 360°-130°-110° = 120°.
However, this is not the value of the question asked. Since the sum of the interior angle of a polygon and its
exterior angle is 180°, the interior angle at vertex Z is 180°-120° = 60°
