a person bikes 2 1/2 miles at a constant rate in 1/8 of an hour what distance , does the person bikes in an hour.​
yuradex [85]

Answer:

20 miles

Step-by-step explanation:

We are given that

Person traveled total distance by bike=2 1/2 miles

Person traveled total distance by bike==2+\frac{1}{2}=2.5miles

Time taken by person ,t=1/8 hour

We have to find the distance traveled by person bike in an hour.

We know that

Rate==\frac{Distance}{time}

Using the formula

Rate=\frac{2.5}{\frac{1}{8}}miles/hr

Rate=20mph

In 1 hour person bike traveled distance=20 miles

Evaluate the absolute value of 54
andreyandreev [35.5K]
| 54 | = 54

the absolute value of a number is just how far that number is from 0. And it is always positive.

in fact...| -54 |...the absolute value of -54 is also 54...because absolute values are positive, even if they say negative

Given four functions, which one will have the smallest y-intercept?
Natalka [10]
F(x) function has a starting value of $6.00 and increases from there.So the y-intercept is 6.

g(x) function shows in the table that when x = 0, y = 6. This is the y-intercept.

h(x) shows on the graph that the y-intercept is  4.

j(x) is an exponential growth function, a * b^x where a is the y-intercept.
y = 10^ x^x has a y-intercept at 10. 

The smallest y-intercept is function h(x).
