Answer:
125 %
Step-by-step explanation:
Computers purchased in the last month = 8
By the middle of the current month, 8 more computers than the last month were purchased. This means, total number of computers purchased by middle of current month = 8 + 8 = 16
Number of computers purchased by end of current month = 2
So,
Total computers purchased by current month = 16 + 2 = 18
We have to find the percentage increase in the number of computers from last month's purchases to the end of this month's purchases. The formula for percentage change is:
Here, Original Value is the number of computers from last month and New Value is the number of computers from current month. Using the values in the formula, we get:
Thus, there was a 125% increase from last month's purchases to the end of this month's purchases
The answer is C.
Think of a pyramid. The base is a rectangle, and the four sides are triangles that meet at the top. If a plane were to intersect this rectangular pyramid perpendicular to the base and through the vertex, then the plane would intersect the pyramid vertically. The resulting cross section would be a trapezoid.
Answer:
Points scored in 3 games is 42
Points scored in 1 game = 42/3 = 14
Points scored in 11 games = 14 x 11 = 154 points

Answer:
112 in^2
Step-by-step explanation:
The equation to calculate the area of a circle is A=πr^2. We can solve for the radius of the circle by:
1) plugging in our known value, A=7. So 7=πr^2
2) dividing both sides by π.
7/π=r^2
3) square rooting both sides.
Sqrt(7/π)=r
Plug that into a calculator and you get about 1.4927
Now we multiply that by 4, giving us our new radius of about 5.9708
Plugging that number back into the equation A=πr^2 as r will give us 112.
So, you're multiplying two consecutive numbers. One of them must be even, and if a factor of a product is even, the result will be even.
