Note: <em>As you have not added the drawing. So, I assume the total number of two-inch cubes are stacked are FIVE. So, I will explain based on that assumption which anyways will clear your concept.</em>
Answer:
The total surface are will be:
Step-by-step explanation:
As we know that
- A cube contains faces of equal area.
So, the total surface area of the cube is equal to multiplied by the area of one of the faces.
As the edge of the cube = 2 inches
So, the area of one of the faces is:
Thus, the total area of the cube is:
Assuming there are total 5 cubes which are stacked, so the total surface are will:
Therefore, the total surface are will be:
Answer:
Option A, SSS Postulate
Step-by-step explanation:
<em>Since it gives you three sides, that means that it is a SSS.</em>
There are no angles given which eliminates 2 options.
Answer: Option A, SSS Postulate
Answer:
Step-by-step explanation:
Let the first angle = x
Let the second angle = y
They are complementary so
x + y = 90
x = y + 30
Substitute for x
y + 30 + y = 90
2y + 30 = 90 Subtract 30 from each side
2y = 90 - 30
2y = 60 Divide by 2
2y/2 = 60/2
y = 30
x = y + 30
x = 30 + 30
x = 60
Answer:
a students test score is likely to increase about 20 pointsfor each hour spent studying.
Step-by-step explanation:
i did the quiz and got it correct!!
First 45 / 10
that is exactly 4.5 meaning there are 4.5 groups of 10 red balloons
63 / 4.5 is 14
There will be 14 blue balloons for every 10 balloons.
Hope this helps :)
