For the last 4.5 hours, the temperature has decreased at a rate of 2.8 Degrees Fahrenheit per hour. Which best represents the overall change in temperature over this time period? –12.6 Degrees Fahrenheit –1.6 Degrees Fahrenheit 1.6 Degrees Fahrenheit 12.6 Degrees Fahrenheit?
Please help me!
Answers
Answer:
The overall change in temperature over the time period ∆T = -12.6°F
Step-by-step explanation:
Rate of change of temperature r = -2.8°F per hour
Time t = 4.5 hours
The overall change in temperature ∆T = Rate of change of temperature × time period
∆T = r × t
∆T = -2.8°F per hour × 4.5 hours
∆T = -12.6°F
The overall change in temperature over the time period is -12.6°F

What is the slope of the line that passes through (3, −7) and (−1, 1)? (1 point)
Answers
Answer:
The slope of the line is -2
Step-by-step explanation:
The rule of the slope of a line is:
[tex]m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex] , where
[tex](x_{1},y_{1})[/tex] and [tex](x_{2},y_{2})[/tex] are two points on the line
Let us find the slope using the rule above
∵ The line passes through points (3, -7) and (-1 , 1)
∴ [tex]x_{1}[/tex] = 3 and [tex]x_{2}[/tex] = -1
∴ [tex]y_{1}[/tex] = -7 and [tex]y_{2}[/tex] = 1
Substitute these values in the rule above to find m
∴ [tex]m=\frac{1--7}{-1-3}=\frac{1+7}{-4}=\frac{8}{-4}=-2[/tex]
∴ The slope of the line that passes through the given points is -2

[tex]180-152= 28\\28+115=143\\180-143=37\\m<1=37[/tex]
Answer:
Step-by-step explanation:
6a. inside the triangle:
x + 62 + 67 = 180
x + 129 = 180
x = 51
For <1: m<1 + 51 = 180
m<1 = 129
6b. for next to the exterior:
x + 152 = 180
x = 28
Inside the triangle:
m<1 = m<1 + 28 + 115 = 180
m<1 + 143 = 180
m<1 = 37

Below is a typical Geometric Two-Column Proof that you will be able to complete by the end of your Geometry course. But right now you only have a few postulates and theorems in your Geometry toolbox. Using what you already know about the Vertical Angles Theorem, fill in Step 3 of this proof.
A. ∠A≅∠D
B. ∠AMB≅∠DMC
C. ∠ABM≅∠DCM
D. ∠C≅∠B
Answers
Answer:
the answer is B.
Step-by-step explanation:
since the M is the middle point of the angles AB and DC.
we just add the M in the middle.
also i did the test and got it right, soooo im 100% sure its B
This is about understanding vertical angles theorem.
Option B is Correct
Vertical angles theorem is an angle theorem that states that when two lines intersect each other, the two opposite vertical angles formed will always be congruent i.e equal to each other.Looking at the image, we can see that the two lines that intersect each other are Line AD and Line BC.
The two opposite angles they form are; ∠AMB and ∠DMC.
Now, from the vertical angles theorem quoted above, we can say that;∠AMB is congruent to ∠DMC.
The congruency symbol is ≅.
Thus; ∠AMB ≅ ∠DMC.

What is an Inverse Function?An Inverse function is found when the variables x and y are interchanged in the f(x,y) function and then the equation is solved for y.
The function is

solve A = 1/2bh for b
Answers
Answer:
[tex]\displaystyle b=\frac{2A}{h}[/tex]
Step-by-step explanation:
Solving an equation
To solve en equation for a given variable, the general method is to isolate the variable by performing inverse operations.
Let's focus on the equation:
[tex]\displaystyle A=\frac{1}{2}bh[/tex]
First, let's flip both sides of the equation:
[tex]\displaystyle \frac{1}{2}bh=A[/tex]
Multiply both sides by 2 since it's dividing the required variable:
[tex]\displaystyle \not 2\cdot \frac{1}{\not 2}bh=2*A[/tex]
Simplifying
[tex]bh=2A[/tex]
Dividing by h:

Driver C had a mean race time of 3.99 seconds and a standard deviation of 0.19 seconds. a. Which driver had the fastest typical race time?
Answers
Answer:
Driver B has the fastest race timeStep-by-step explanation:
From the options presented, driver B has the fastest typical race time because he recorded the smallest time taken to complete an individual race.
Also from the standard deviation given (3.96) for driver B, it shows that the individual time spread from the standard deviation is minimal and that the driver maintained a fairly consistent time of race throughout the racing period.

Of course, that is incorrect. What is the mean score for all ninth graders in the city? USE EXCEL. Round your answer to one decimal place.
Answers
Answer: 83.56
Step-by-step explanation:
To calculate the mean score for all ninth graders in the city, we multiply the mean score test for each school by the number of months grade students and then add all together and divide by the total ninth grade students. This is solved below.
Mean = [(79 × 285) + (94 × 336) + (72 × 191)]/285+336+191
= (22515+31584+13752)/812

Answer:
x = 124°y = 88°z = 92°Step-by-step explanation:
find:
1) x
2) y
3) z
solve for x:
1) opposite angle are equal.
x = 124°
solve for y:
2) inside angle of a triangle = 180
180 = 53 + 39 + y
180 - 53 - 39 = y
y = 88°
solve for z:
3) z + y = 180
substitute y = 88
z + 88 = 180
z = 180 - 88
z = 92°

Step-by-step explanation:
Given that :
Objective is to compete in a 5km road race ;
Reduction in race tone per month = 15 seconds
Rqce comes up in 3 months
Total change in race time he hopes to achieve :
1. What integer represents the change in race time Riley wants to achieve each month ; 15 seconds
2. What integer represents the number of months she will train?
She will train for 3 months ; 3 months
Write a multiplication expression that can be used to find the total change in time.
Change in race time * number of month she will train
15 seconds * 3 months = 45 seconds
Let initial race time = (t)
t - 15(month in which race comes up).
t - (15-3) = t - 45
