Answer:
Step-by-step explanation:
This is permutation question
<u>The formula for it: </u>
- N = b!/(b-s)!, where N- number of ways, b- number of books, s- number of slots
<u>Finding the answer:</u>
- N = 7!/(7-5)! = 7!/2! = 7*6*5*4*3 = 2520
To calculate this, we need to do the following:
92 * 115 = 10580 (we first multiply the percentage with our number)
10580 / 100 = 105.8 (and divide what we get by 100 to get the final answer)
And this is also already the answer: 105.8
Answer:
Total gallon of fuel used =
gallons
Step-by-step explanation:
Given -
The total distance travelled by car in one gallon of gas = 21 miles
Total distance travelled each day = 48 miles
Number of days days in a week in which Candice drive is 5 days
Total miles travelled per week =
= 240 miles
Total gallon of fuel used =
gallons
Answer:
D. 8/2 +(-10)² = 104
Step-by-step explanation:
To find which statements are true, evaluate the expression for the given variable values. You do this by putting the numbers in place of the respective variables, then doing the arithmetic.
The respective expression values are ...
A 83 ≠ 37 . . . . (4/2) +9² = 2 +81 = 83
B 31 ≠ 61
C 52 ≠ 61
D 104 =104 . . . . true statement

I find it less tedious to write a function into a calculator or spreadsheet and let it do the repetitive math. Examples of the calculation are shown above.
