The tree diagram shows that there are a total of six sample
spaces.
math------science
art
science---math
art---math
science
math---art
art---science
math
science---art
Based on the tree
diagram, the probability that the science project is first is two over six.
This is because science appears first in two out of the six sample spaces (boldened).
Answer:
5
Step-by-step explanation:
10,000,000÷2,000,000=5
(1x10^7)÷ (2x10^6) = 5
Okay, so the rate is 1 job / hours, so:
1/3 + 1/7 (This covers both their work rates) = 1/n (n represents the time it take for them to work together)
Get the LCD:
7/21+ 3/21 = 1/n
10/21 = 1/n
Cross multiply:
10n = 21
n = 2.1
It will take them 2.1 hours, or 2 hours and 6 minutes
-3 x -2 = 6
-3 + -2= -5
answer is -2
