Answer:
Number of trucks = 28
Number of cars = 14
Number of SUVs = 46
Total number of vehicles = 88
Step-by-step explanation:
Let T = the number of trucks, C = the number of cars, and S = the number of SUVs washed.
We are told :
They washed twice as many cars as trucks.
Hence: T = 2C
They washed a total of 28 trucks and cars and SUVs
Number of trucks = 28
Number of Cars =
T= 2 C
C = T/2
C = 28/2
C = 14
The number of trucks washed was 2 fewer than half the total number of cars and SUVs washed.
T = 1/2(C + S) - 2
T = 28
C = 14
Hence:
28 = 1/2(14 + S) - 2
28 = 1/2(14) + 1/2(S) - 2
28 = 7 - 2 +S/2
28 - 7 + 2 = S/2
30 - 7 = S/2
23 = S/2
S = 23 × 2
S = 46
Hence, number of SUVs = 46
Total number of vehicles = 28 + 14 + 46
= 88
Answer: the fraction for number 2 is 5/16, the decimal is 0.3125 this number as a percent is 31.25%
Step-by-step explanation: you're supposed to add all the numbers and the number you're being asked to find the probability of /the 5 nickels they were talking about, you divide 5/16 get 0.3125, then move the decimal over 2 spaces leaving you with 31.25% so number 2 is (fraction: 5/16, Decimal: 0.3125, percent: 31.25
now if you add one dime 1 quarter and 2 pennies then you have 19 total
so 5/19=0.263 then turn 0.263 into a percent it's 26.3 (slide the decimals over twice) so now you have ( fraction: 5/19, decimal: 0.263, fraction: 26.3)
