1. [(24÷12)⋅6]+3⋅8÷2 = (2⋅6) + 3⋅8 /2 = 12 + 12 = 24

2.(26÷13)⋅(−7)+14−4 = 2 ⋅ (-7) + 14 - 4 = -14 + 14 - 4 = -4

3.9 + 3 × 2 = 6 + 9 = 15

4.6⋅[(32−8)÷4+2] = 6 ⋅ (24 / 4 + 2) = 6 ⋅ (6+2) = 6 ⋅ 8 = 48

5.6y+5z+8y−3z = 14y + 2z

Can someone help me with 16 and 20? If you’re supposed to write a contrapositive and inverse, but the word not is already in the statement, what do you do?

Answers

Since 2 'not's cancel out, 16's contrapositive is 'If the light will go on, then the fuse has not blown'. In addition, the inverse would be 'If the fuse has not blown, then the light will go on'. I challenge you to do 20 using this information!

Write the equation of the line that is perpendicular to 5x+8y=16 and passes through (-5,7).

Answers

In order to do this problem, we should first put the equation in slope-intercept form, and then consider the relationship between the slopes of perpendicular lines. 
Slope Intercept form (y=mx + b), m=slope, b=y-intercept
5x + 8y = 16         Subtract 5x from both sides
8y=-5x + 16          Divide both sides by 8
y= (-5/8)x  + 2

This is our line in slope-intercept form. What will the slope be of a line that is perpendicular to this one? It will be the opposite inverse of the slope of our equation. The opposite inverse means flipping the numerator and denominator, and multiplying by negative one.
Our slope = -5/8, so the opposite inverse is 8/5.

The slope of our perpendicular line will be 8/5
In slope intercept form, our line will be 
y=(8/5)x + b
We know it passes through the point (-5,7), so we can plug in -5 for x and 7 for y in order to find b:
7 = (8/5) * -5 + b
7 = 8 *-1 + b        Add 8 to both sides
15 = b
Plugging in b, we can get our general function in slope-intercept form:

y= (8/5)x + 15

A moving company charges a $2,000 fee plus $100 per hour. Another moving company charges an $1,800 fee plus $150 per hour. How long is a job for which the two companies' costs are the same?

Answers

The costs of two moving companies are the same for a job that lasts 4 hours.

To find out how long a job must last for the two companies' costs to be the same, we need to set up an equation where both company costs are equal and solve for the time variable, which I will denote as 't' hours.

The first moving company's cost can be represented as:$2,000 + $100 x t.

The second moving company's cost can be represented as: $1,800 + $150 x t.

To find the time when both costs are the same, we set the two expressions equal to each other:

$2,000 + $100t = $1,800 + $150t

Now, we need to solve for 't' by subtracting $100t from both sides and subtracting $1,800 from both sides:

$200 = $50t

Divide both sides by $50 to isolate 't':

t = 4 hours

So, the two companies would have the same cost for a 4-hour job.

The angles below are supplementary. what is the value of x? a pair of supplementary angles is shown. one angle measures 5x plus 20 degrees, and the other angle measures 50 degrees. 4 6 14 22

Answers

5x + 20 + 50 = 180
5x + 70 = 180
5x = 180 - 70
5x = 110
x = 110/5
x = 22 <===

The measure of the value 'x' for the supplementary angles will be 22. The correct option is D.

What are supplementary angles?

If two angles add up to 180 degrees, they are said to be supplementary angles. When supplementary angles are combined, they form a straight angle (180 degrees).

In other words, if Angle 1 + Angle 2 = 180°, angles 1 and 2 are supplementary. Angles 1 and 2 are referred to as "supplements" in this case.

The measure of the value x will be calculated as:-

5x + 20 + 50 = 180

5x + 70 = 180

5x = 180 - 70

5x = 110

x = 110/5

x = 22

Hence, the value of x will be 22.

What can be divided into 5 AND 8? 40!

How many times can 40 be divided into 5? 8 times!

How many times can 40 be divided into 8? 5 times!

So, you take that number and multiply it by the numerator (top number) and you get your new yet equivalent fraction.

3/5 turns into 24/40 & 5/8 turns into 25/40

So, our new question looks like this :

24/40 + 25/40

Since both of these fractions have the same denominator (bottom number), you can simply add the top numbers together! :)

24 + 25 = 49

So, our answer to 3/5 + 5/8 = 49/40

Turn this into a mixed number.

If a function f(x) is the temperature in degrees as a function of time in minutes. then the function f'(x) is

Answers

f'(x)  is the instantaneous change of temperature at  a specific time in minutes.

In the context of a function representing temperature over time, the derivative f'(x) indicates the rate of change of the temperature with respect to time.

If a function f(x) represents the temperature in degrees as a function of time in minutes, the function f'(x) represents the rate of change of temperature with respect to time. This implies that if you have the temperature reading from a thermometer at different times, f'(x) tells you how quickly the temperature is rising or falling at any given moment. The concept of the derivative as the rate of change applies to many types of functions beyond just temperature over time.

what is cos of negative pi/3?
what is sin of negative pi/3?

Answers

pi/3 is equivalent to 60 degrees, as 2pi is equal to 360 degrees. cos(60) in a triangle yields 1/2, and sin(60) yields (3^(1/2))/2. Thus, -pi/3, or -60 degrees would be a fourth quadrant point on the unit circle and these values would be negative as well, at cos(-pi/3)=-1/2 and sin(-pi/3)=-(3^(1/2))/2 
Cosine is even function, so:

[tex]$\cos(-\frac{\pi}{3})=\cos(\frac{\pi}{3})=\frac{1}{2} [/tex]

and sine is odd function, so:

[tex]$\sin(-\frac{\pi}{3})=-\sin(\frac{\pi}{3})=-\frac{\sqrt{3}}{2} [/tex]

5c - 5 = 90

5c - 5 + 5 = 90 + 5
