<u>Given</u><u>:</u>
- Area of rectangular prism ( cuboid ) = 448 cm²
<u>To</u><u> </u><u>find</u><u> </u><u>out</u><u>:</u>
Find the height, h ?
<u>Formula </u><u>used </u><u>:</u>
Area of rectangular prism ( cuboid ) = 2 ( lb + bh + hl )
<u>Solution</u><u>:</u>
We know that that,
Area of rectangular prism ( cuboid ) = 2 ( lb + bh + hl )
=> 448 = 2 ( 14 × 6 + 6 × h + h × 14 )
=> 448 = 2 ( 84 + 6h + 14h )
=> 448 = 2 ( 84 + 20h )
=> 448 = 168 + 40h
=> 40h = 448 - 168
=> 40h = 280
=> h = 280/40
=> h = 7 cm
Answer:
5 < x < 13
Step-by-step explanation:
9+4 > x
4 + x > 9
A 2 - - 7 = 9
b - 3 - - 4 = 1
c - 5 - 6 = - 11
d - 3 - - 5 = 2
Y = x + 4
y = 3x + 6
set them equal..
x + 4 = 3x + 6 <==
Answer:
78.88%
Step-by-step explanation:
We have been given that
The z-score formula is given by
For
For
Now, we find the corresponding probability from the standard z score table.
For the z score -1.25, we have the probability 0.1056
For the z score 1.25, we have the probability 0.8944
Therefore, the percent of the trees that are between 20 and 30 years old is given by
0.8944 - 0.1056
= 0.7888
=78.88%
