Answer:
The surface area is 
Step-by-step explanation:
The surface area of a rectangular prism is calculated using the formula;
![S.A=2[lw+lh+wh]](https://tex.z-dn.net/?f=S.A%3D2%5Blw%2Blh%2Bwh%5D)
The length of the rectangular prism is
The height is 
The width is 
The surface area
![S.A=2[10(8)+10(6)+8(6)]](https://tex.z-dn.net/?f=S.A%3D2%5B10%288%29%2B10%286%29%2B8%286%29%5D)
![S.A=2[80+60+48]](https://tex.z-dn.net/?f=S.A%3D2%5B80%2B60%2B48%5D)


Answer:
C
Step-by-step explanation:
given the fact that the other side measures all multiply by 4 when they are enlarged in the second shape, we know that the scale factor is 4. 3 enlarged by a scale factor of 4 = 12
Answer:
The answer is 62
Step-by-step explanation:
You just need to simply divide. 992÷16 is equivalent to 62 with no remainder.
95% of red lights last between 2.5 and 3.5 minutes.
<u>Step-by-step explanation:</u>
In this case,
- The mean M is 3 and
- The standard deviation SD is given as 0.25
Assume the bell shaped graph of normal distribution,
The center of the graph is mean which is 3 minutes.
We move one space to the right side of mean ⇒ M + SD
⇒ 3+0.25 = 3.25 minutes.
Again we move one more space to the right of mean ⇒ M + 2SD
⇒ 3 + (0.25×2) = 3.5 minutes.
Similarly,
Move one space to the left side of mean ⇒ M - SD
⇒ 3-0.25 = 2.75 minutes.
Again we move one more space to the left of mean ⇒ M - 2SD
⇒ 3 - (0.25×2) =2.5 minutes.
The questions asks to approximately what percent of red lights last between 2.5 and 3.5 minutes.
Notice 2.5 and 3.5 fall within 2 standard deviations, and that 95% of the data is within 2 standard deviations. (Refer to bell-shaped graph)
Therefore, the percent of red lights that last between 2.5 and 3.5 minutes is 95%
Answer & Step-by-step explanation:
This can be proven with the SAS theorem (side-angle-side)
With a perpendicular bisector, the line it bisects is cut directly in half. This creates two equal sides:
and it creates two 90° angles:
∠
∠
And because of the reflexive property of congruence:

Side-Angle-Side.
