Answer:
63 minutes
Step-by-step explanation:
Set up a ratio equation.
(8 miles/84 minutes should be equal to 6 miles/x amount of minutes). Set the two fractions equal to each other and solve for x by cross multiplying.
Answer: It will take Dan 63 minutes to run 6 miles.
Step-by-step explanation:
=
do cross product.
8x = 504
x= 63
Answer:
55 mph
Step-by-step explanation:
Let x represent Bob's speed. Then John's speed is x+10, and their respective times are found by ...
time = distance/speed
330/x = 390/(x+10) . . . . . . . the times are the same
330(x +10) = 390x . . . . . . . multiply by x(x+10)
3300 = 60x . . . . . . . . . . . . . subtract 330x
55 = x . . . . . . . . . . . . . . . . . . divide by the coefficient of x
Bob is driving at 55 miles per hour.
1. a=0
2. b=2
3. b=-2
4. none of the above
Answer: The correct option is (2)
Step-by-step explanation: We are given to find the exclude value for the following algebraic expression:
We know that
for a rational expression, we must exclude those values for which the denominator of the fraction becomes zero.
So, in equation (i), the excluded value will be given by
Thus, the required excluded value is
Option (2) is CORRECT.
Product A is 8 oz and sells for = $1.36
So, 1 oz of Product A will cost = = $0.17
So, unit price of product A is $0.17
Product B is 16 oz and sells for = $3.20
So, 1 oz of product B will cost = = 0.20
Unit price of product B is $0.20
Hence, comparing the two unit prices, Product A has a lower unit price.
Answer: $52.5
Step-by-step explanation:
Given : Last month you used 125 minutes and your bill was $37.50.
i.e. Charges for each minute used =
i.e. it charges $0.3 for each minute home phone used.
If this month you used 175 minutes.
Then , your this month's home phone bill will be :-
Hence, you month home phone bill will be $52.5 .
