A bill for repairing the breaks on the Johnsons car was $125.25. If 20% of the bill was for parts and the rest for labor, how much were the Johnsons charged for labor?
Answer:
181
Step-by-step explanation:
Assuming that the 'x's' all symbolize multiplication, follow these steps.
First, begin with the innermost set of parenthesis: 3x2
This will give you the answer of six, this will now give you the new equation of:
13+[9x(6)-12]x4
Following the rules of PEMDAS (Parenthesis, Exponents, Multiplication, Division, Addition, and Subtraction), it is inferable that you must multiply before subtracting the twelve.
Perform this step: 9x6 to get the answer of 54.
13+[54-12]x4
Now, as there are still brackets, perform the bracketed information:
54 - 12 = 42
This now gives you: 13+[42]x4
Yet again, following the rules of PEMDAS, you multiply 42x4 then add the result of that to 13.
42x4 = 168
168 + 13 = 181
Therefore, this expression provides the answer of 181.
Hope this helps!
Probability is represented as the number of ways for an event to happen over all possible outcomes. For the theoretical probability, there is 1 black spot and 5 total options. Therefore, the probability is 1/5, or 0.20.
For experimental probability, there were 103 times it landed on black out of 500 spins. The probability is 103/500, or 0.206.
Lastly, the multiple choice. The larger sample size you take, assuming a fair spinner, the more likely you are to see results similar to the theoretical probability. This is because the larger sample size taken, the less each individual spin effects the outcome.
Well 2.5 + 2.5 is 5 so 5 - 2.5 is 2.5
Answer:
Option d) 115 degrees
Step-by-step explanation:
We are given a trapezium ABDE in the picture. AB and ED are the parallel sides.
F is the mid point of AE and C the midpoint of BD. FC is joined.
We are also given that angle of AED = 65 degrees.
To find the measure of angle BAE.
Since sides AB and ED are parallel sides we find that AE is the transvesal intersecting the two parallel lines.
Hence by parallel lines axiom, the two interior angles namely Angle AED and BAE are supplementary.
i.e. 65 +angle BAE=180
Hence angle BAE = 115 degrees.
Option d is the answer.
