For this case we have that the temperature drops steadily at a speed of {\sf0.8\:\frac{degree}{hours}}, that is, every hour drops 0.8 degrees. So, we can propose a rule of three:

1 hour ----------> 0.8 degrees

x ------------------> 4.4 degrees

Where the variable "x" represents the number of hours that must pass for the temperature to decrease by 4.4 degrees.

{\sf{x\:=\:\frac{4.4\:x\:1}{0.8}

{\sf{x\:=\:5.5

Thus, for the temperature to decrease by 4.4 degrees, 5.5 hours must pass.

<u>Answer:</u>

5.5 hours

The points (6, -3) and (7, -10) fall on a particular line. What is its equation in point-slope form? Use one of the specified po
kumpel [21]

Answer:

Step-by-step explanation:

Given the coordinate points (6, -3) and (7, -10), we are to find the equation of a line passing through this two points;

The standard equation of a line is y = mx+c

m is the slope

c is the intercept

Get the slope;

m = Δy/Δx = y2-y1/x2-x1

m = -10-(-3)/7-6

m = -10+3/1

m = -7

Get the intercept;

Substitute the point (6, -3) and m = -7 into the expression y = mx+c

-3 = -7(6)+c

-3 = -42 + c

c = -3 + 42

c = 39

Get the required equation by substituting m = -7 and c= 39 into the equation y = mx+c

y = -7x + 39

Hence the required equation is y = -7x + 39

Let i be the first of four consecutive integers. what is 3 less than the sum of those integers ?
Dmitrij [34]
The consecutive integers are i, i+1, i+2, i+3.

3 less than sum of the integers

= i + i +1 + i + 2 + i + 3 - 3 = 4i + 3

Find the slope for the pair of points (1,1)(4,-4)
wolverine [178]
(1, 1) and (4, -4)

Slope formula is : m = (y₂-y₁) / (x₂-x₁)

In this case :

x₁ = 1 ; x₂ = 4 ; y₁ = 1 ; y₂ = -4

Now that you know what variable counts as what, we simply just need to plug everything in.

m = (-4 - 1) / (4 - 1)

Simplify.

m = -5/3

Therefore, your slope is -5/3

A restaurant sells burritos for $8.00 each. The cost of the meat is $1.50 and the cost of the other ingredients is $1.00 for eac
Zina [86]

Answer: $550

Step-by-step explanation:                                                                                                                            

How much is the profit for 1 burrito?: $8 - ($1.50+$1) = $5.5

So, profit for 100 burritos is $5.5 x 100 = $550.

Hope this helps.
