Darius filled up his gas tank with 24 gallons of gas. For each mile that he drives, he uses 0.06 miles of gas. (THE REST OF THE QUESTION IS DOWN BELOW, PLEASE HELP!)
Answer:
400 miles
Step-by-step explanation:
Step one:
Given data
Darius filled up his gas tank with 24 gallons of gas
Required
The distance 24 gallons will cover
Step two:
1 mile will take 0.06 gallons
hence x miles will take 24 gallons
cross multiply we have
0.06x= 24
divide both sides by 0.06
x= 24/0.06
x=400 miles

Answer:
20x-60=280
Equation
So x for unknown amount of months, since 20 dollar each month 20x
-60 becuase she withdraws 60 one time
=280 becuase thats what she has left
Now solve
add 60 on both sides
20x=340
Divide 20 on both sides
x=17

Leroy borrowed P1500 at an annual simple interest rate of 12%. He paid P270 in interest. For what time period did Leroy borrow the money? A. 8 years B. 5 years C. 18 months D. 18 years
Answer:
C. 18 months
Step-by-step explanation:
Given data
Principal= P1500
rate= 12%
Simple interest= P270
We know that
Simple interest= PRT/100
substitute
270= 1500*12*T/100
cross multiply we have
270*100= 1500*12*T
27000= 18000 T
divide both sides by 18000
T= 27000/18000
T=1.5 years
That is 12 months + 6 months
in all = 18 months
The time is C. 18 months
An elementary school bus comes at 8:15 am every morning to pick up children in a neighborhood. The probability that the bus will be late is 0.19 and the probability that the bus will be early is 0.02.
What is the probability that the bus will arrive early next two days?
What is the probability that the bus will arrive on time next two days?
In two or more complete sentences, explain your calculations for parts A and B. In your explanation, include their similarities and differences.
Answer:
a. .02 * .02 = .0004
b. (1 - .02 - .19) = .79; .79*.79 = .6241
Step-by-step explanation:
The probability that the bus will arrive on time next two days is 0.79, The probability that the bus will arrive early next two days is 0.0004.
What is Probability?Probability is the likeliness of an event to happen, it has a range from 0 to 1.
Probability that the bus will be late is 0.19
Probability that the bus will be early is 0.02.
The probability that the bus will arrive early next two days is
= 0.02 * 0.02
=0.0004
The probability of coming early one day is small and the probability that it will come early two days in a row is smaller.
The probability that the bus will arrive on time next two days
= (1 - 0.02 -0.19) = 0.79
The probability that the bus will come on time is more as the probability of coming early or late is less.
