Identify the type of solution from a graph.

Juan starts walking at 4 miles per hour. An hour and a half later, Cathy starts jogging along the same route at 7 miles per hour

kifflom [539]

Answer:

The answer to your question is 2 hours

Step-by-step explanation:

Data

Juan speed = 4 mi/h

Cathy speed = 7 mi/h

t = x

Formula

speed = distance/time

Solve for distance

distance = speed x time

d = s x t

Distance travelled by Juan

d = 4t

Distance travelled by Juan in 1.5 h

d = 4(1.5)

d = 6 mi

total distance d = 6 + 4t

Distance travelled by Cathy

d = vt

d = 7t

Equal both equations

6 + 4t = 7t

Solve for t

6 = 7t - 4t

6 = 3t

6/3 = t

2 = t

Cathy wll catch up with Juan in 2 hours

mojhsa [17]

Complete Question

The relationship between altitude and the boiling point is linear. At an altitude of 8300ft, the liquid boils at 194.23 ° F

At an altitude of 4200 ft , the liquid boils at 202.02° F.

Write an equation giving the boiling point b of the liquid, in terms of altitude a in feet . feet . What is the boiling point of the liquid at 2600ft

Answer:

The equation is $y = -0.001943x + 210.3569$

At 2600ft the temperature is $y = 205.3051 \ °F$

Step-by-step explanation:

From the question we are told that

The temperature at 8300ft is 194.23 ° F

The temperature at 4200 ft is 202.02° F

Generally the slope for this relationship is mathematically represented as

$m = \frac{ 202.2 - 194.23}{ 4200 - 8300}$

=> $m = 0.001943 ^o F / ft$

Generally the according to the point slope formula is

$y - y_1 = m(x -x_1 )$

=> $y - 194.23 = -0.001943 (x - 8300 )$

=> $y - 194.23 = -0.001943x + 16.1269$

=> $y = -0.001943x + 210.3569$

Now we are given from the question that x = 2600 ft

Then

$y = -0.001943(2600) + 210.3569$

=> $y = 205.3051 \ °F$

Ymorist [56]

Tina increased 40% time from Tuesday to Thursday

Step-by-step explanation:

The percent increase is given by:

$Percent\ increase = \frac{Increase}{Initial\ Value}*100$

Where

$Increase = Current\ value- initial\ value$

Here given

Increase = 10 minutes

Initial value = 25 minutes

So the percentage increase will be:

$Percent\ increase = \frac{10}{25}*100\\= 0.4*100\\=40\%$

Tina increased 40% time from Tuesday to Thursday
