To find the rate in miles per hour, divide the miles by the hours.
(1 1/2 miles)/(3/5 hour) =
= 3/2 miles * (5/3 hour)
= 5/2 mph
= 2 1/2 mph
Her walking rate is 2 1/2 mph.
(4 1/2 miles) / ( 2 1/2 mph) =
= 9/2 miles / (5/2 mph)
= 9/2 * 2/5 hours
= 9/5 hours
= 1 4/5 hours
From 9:00 a.m. to 11 a.m., she has 2 hours, but she only needs 1 4/5 hours to walk, so she will make it to work on time.
Answer: it is c
Step-by-step explanation:
if it is leaking 3/4 in 1/2 h than it will leak 6/4 in one whole hour
Given:
The equation of a line is
To find:
The slope and y-intercept of the line.
Solution:
We have,
...(i)
The slope intercept form of a line is
...(ii)
Where, m is the slope and b is the y-intercept.
On comparing (i) and (ii), we get
Slope of the line = 1
y-intercept of the line = -4
The coordinate form of y-intercept is (0,b). So, the y-intercept of the given line is (0,-4).
Therefore, the slope of the line is 1 and the y-intercept is (0,-4).
As the focus is at (0,5) it will be symmetrical about the y axis and will open upwards
General formula is x^2 = 4ay where a is the y coordinate of the focus
So its y = x^2/5*4
y = 1/20 x^2
Answer:
Part A: x=3
Part B: 6oz
3x=18
Step-by-step explanation:
Part A-
So, he needs 3 oz for each sandwich.
This gives us 3 for the equation.
The question says that we need an equation for this.
If we need an equation, we could write something like
x=3
There's really not anything else that we could write here.
Part B-
We now have something that we need to write.
He has 18 oz for sandwiches.
Each sandwich needs 3 oz.
So, we can write something like 3x=18
Then we could solve the equation by dividing both sides by 3.
This will leave us with x=6
Hope this works!
