Answer:
c. 135 hr
Step-by-step explanation:
The following method of converting units is called "dimensional analysis."
Write every conversion factor as a fraction. Each conversion factor fraction equals 1, so it changes units but not the value. In the end, all the undesired units cancel out leaving the desired units. Multiply the given amount by the necessary conversion factors until you arrive at the desired units.
Answer:
1. is a 30 60 90 triangle so x = 30
pardon my bad handwriting for below
2.
STEP 1: subtract the angle you have from 180
STEP 2: add your x values together, if there is a non x number (such as + 10) balance it out on the other side by adding or subtracting
STEP 3: divide so that x has no coeffecient in front of it
STEP 4: substitute x values with the value you got
STEP 5: verify by adding the angles you got, it'll be correct if it equals 180
Answer:
14.29% probability that Marlon's friend will think of the number 9
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
In this problem, we have that:
There are 7 numbers from 5 to 11(5,6,7,8,9,10,11)
9 is one of them
So
14.29% probability that Marlon's friend will think of the number 9
