Bus A travels according to the function y = 125 /2 x where y is distance traveled in miles and x is time in hours. Bus B travels according to the graph below, where the distance y is a function of time x . Which bus travels faster? Include all necessary calculations in your final answer.

Answers

Answer:

Bus B travels faster.

Step-by-step explanation:

The graph of the question in the attached figure

we know that

the linear equation in slope intercept form is equal to

where

m is the slope

b is the y-intercept

x ---> is the time in hours

y ---> is the distance in miles

In this problem we have

Bus A

The slope of the linear equation represent the speed of the bus

so

The speed of bus A is

Bus B

Find  the slope

take two points from the graph

(0,0) and (3,200)

The formula to calculate the slope between two points is equal to

substitute

Compare the slope Bus A with the slope Bus B

therefore

Bus B travels faster.

i bought a box of fruit snacks worth $9.98, there are 90 packs of fruit snacks in the box. How much is each pack of fruit snacks worth ? please help

Answers

Answer:

About $0.11

This is because 0.11 is how much money one pack is Worth.

Answer:

Cost of each pack = $0.11

Step-by-step explanation:

Given information,

→ Total cost of the snacks = $9.98

→ Total packs in the box = 90 packs

Now we have to,

→ Find the cost of each pack.

Let us assume that,

→ Cost of each pack = x

Forming the equation,

→ x × 90 = 9.98

Then the value of x will be,

→ x × 90 = 9.98

→ 90x = 9.98

→ x = 9.98 ÷ 90

→ [ x = $0.11 ]

Hence, the value of x is 0.11.

On average, employees at a particular company miss 1 day of work per year. That is 75% less than it was historically, back before there were major management changes. What was the average back then?

Answers

Answer:

4 miss days per year

Step-by-step explanation:

Let the previous employees miss days be = x

As given, miss days now are 75% less than previous

x - 75%x = 1/365

0.25x = 1/365

x = 1 / (365 x 0.25)

x = 4/365

So, average back then could have been 4 days per 365 days
