Answer:
speed conversion. feet into inches and minutes into seconds.
120 inches/sec
Step-by-step explanation:
600 ft / min
youd multiply feet into inches and minutes into seconds
so since 12 inches are in a foot it would be 600 feet x 12 inches
and there are 60 seconds in a minute so 1 minute x 60 seconds
600 x 12 = 7200
1 x 60 = 60
now you divide 60 into 7200
7200 inches / 60 seconds = 120 inches per second
120 inches / second
Answer:
x = number of quarters = 25
y = number of dimes = 15
Step-by-step explanation:
Let
x = number of quarters
y = number of dimes
1 dime = $0.10
1 quarter = $0.25
x + y = 40 (1)
0.25x + 0.10y = 7.75 (2)
From (1)
x = 40 - y
Substitute x = 40 - y into (2)
0.25x + 0.10y = 7.75 (2)
0.25(40 - y) + 0.10y = 7.75
10 - 0.25y + 0.10y = 7.75
- 0.25y + 0.10y = 7.75 - 10
-0.15y = -2.25
y = -2.25/-0.15
y = 15
Substitute y = 15 into (1)
x + y = 40 (1)
x + 15 = 40
x = 40 - 15
x = 25
x = number of quarters = 25
y = number of dimes = 15
Total quarters = 25 × $0.25
= $6.25
Total dimes = 15 × $0.10
= $1.5
Answer:
(20 - 24)/6
Step-by-step explanation:
We have the algebraic expression
6(x + 4)= 20
We expand the brackets
6x + 24 = 20
Collect like terms
6x = 20 - 24
x = (20 - 24)/6
A correct solution to the expression is
(20 - 24)/6
Given that a vehicle travels 25 miles in 2 hours, determine the average speed of the vehicle in miles per hour.
Work:
In order to find the average mph of the vehicle, you have to divide the distance the vehicle travels in a certain period of time by that amount of time.
So, in this case, the vehicle traveled 25 miles in 2 hours, so you would divide 25 by 2.
25/2 = 12.5
That means, the vehicle is traveling at a speed of 12.5 mph.
Thus, the average speed of the vehicle is 12.5 miles per hour (mph).
The shortest distance between two points would be a straight line
