Answer:

-1°F

Step-by-step explanation:

10AM = -15

11AM = -13

12AM = -11

1PM = -9

2PM = -7

3PM = -5

4PM = -3

5PM = -1

or 10AM to 5PM is 7 hours and 2*7 = 14, so them -15 + 14= -1

The sum of two numbers is 24 and their difference is . what are the numbers

Darina [25.2K]

X + y = 24
x - y = 2
-------------add
2x = 26
x = 26/2
x = 13

x - y = 2
13 - y = 2
-y = 2 - 13
-y = - 11
y = 11

ur numbers are 11 and 13

janie has 196 rock and country cd's that she listens to at home if there are 76 more rock cd's than country cds how many of each

marshall27 [118]

There are 60 Country CDs and 136 Rock CDs.

Rock and country CDs = 196

Country CD = x
Rock CD = x + 76

Country CD + Rock CD = 196
x + (x + 76) = 196
2x = 196 - 76
2x = 120
2x / 2 = 120 / 2
x = 60 * number of Country CD

Rock CD = x + 76 = 60 + 76 = 136

To check:
Country + Rock = 196
60 + 136 = 196
196 = 196

the relationship between altitude and the boiling point is linear.AT an altitude of 8300ft 8300 ft , the liquid

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

$y = -0.001943(2600) + 210.3569$

=> $y = 205.3051 \ °F$
