Answer:
6.8 cubic feet
Step-by-step explanation:
7.3/4=1.825, which is the side length, 1.825*1.825=20.2575 and then ypu divide 20.2575 by 3 because it is a pyramid and that gives you 6.7525
Answer:
The prove that the value of the expression : 38^9–38^8 is divisible by 37 is 38 ÷ 37
Given:
38^9–38^8 is divisible by 37
=
The exponents in scientific notation should be added or subtracted
= 38¹ ÷ 37
= 38 ÷ 37
Therefore, the expression : 38^9–38^8 is divisible by 37 is 38 ÷ 3
Step-by-step explanation:
First, we need to figure out the probability of landing on white one time. The probability of landing on black is 1/2, and the probability of landing on red is 1/3. If we add these probabilities together we get:
![\frac{1}{2}+ \frac{1}{3} = \frac{3}{6}+ \frac{2}{6} = \frac{5}{6}](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7B2%7D%2B%20%5Cfrac%7B1%7D%7B3%7D%20%3D%20%20%5Cfrac%7B3%7D%7B6%7D%2B%20%5Cfrac%7B2%7D%7B6%7D%20%3D%20%20%5Cfrac%7B5%7D%7B6%7D%20%20%20)
So if there is a 5/6 chance of NOT landing on white, then there must be a 1/6 chance of landing on white.
To find the probability of landing on white 4 times, multiply 1/6 to itself 4 times.
![( \frac{1}{6})^4 = \frac{1}{1296}](https://tex.z-dn.net/?f=%28%20%5Cfrac%7B1%7D%7B6%7D%29%5E4%20%3D%20%5Cfrac%7B1%7D%7B1296%7D%20)
The answer is D.
Answer:
x=2/3
Step-by-step explanation:
25-(3x+5)=2(x+8)+x
25-3x-5=2x+16+x
20-3x=3x+16
20-3x-3x=16
20-6x=16
6x=20-16
6x=4x=4/6
simplify
x=2/3
Answer:
About 32º
Step-by-step explanation:
since 17 m is one leg, and 20m is the hypotenuse, we can write:
cos (x) = 17/20
x = cos-1(17/20)
x is about 32º
