Answer:

97.5

Step-by-step explanation:

Supplementary angles always add up to 180.

180 - 82.5 = 97.5

Answer:

97.5

Supplementary means they add up to 180 degrees.

So just subtract 82.5 from 180. You get 97.5

In your own words, explain to me what is absolute value? . Make sure to talk about the definition of it, how you find it, and how it's different from just plotting an integer on a number line. You must provide 3 sentences or more.

Answers

Answer:

Absolute Value Is Pretty Simple Actually In Middle School Math. Absolute Value Refers To The Numerical Difference From 0 To The Integer. To Find Absolute Value All We Have To Do Is Find The Difference From 0 To The Number. For Example -9 The Absolute Value Is 9 Because On A Numberline There Are 9 Spaces Between 0 and -9 and +6 Is 6.

Khan Academy Slope from graph !! Please help me I am having so much trouble !!!! PLEASEEE HELPPPPPPPP

Answers

I think the slope is 3/2

Answer:

The slope of this line is 5/3. Or, 1 2/3. The equation would be y = 5/3x

Step-by-step explanation:

You are in luck my friend!

To find the slope of a line on a graph, you need to find the rise over run. You need to pick two definite points on a graph. An intersection whereyou can clearly tell the value. For example 1,1 and -4,-4. Then use your finger and trace how many units up you have to go, and then how many units across. (This is a very common topic so if you need further help just look up rise over run. This fact will put you ahead, do you see how the line intersects between the 2 and the 3 in the y axis? This is called the y intersect, you will see it added to the slope so if the equation is y = 5/3x it would be written as y = 5/3x + 2.5 because that is where the line intersects with the y axis.) Back to slope, remember that the formula is always rise/run. Later, you will find to points and use a slope formula. y2-y1/x2-x1.

Answers

Answer:

See Below

Step-by-step explanation:

Lets look at our numbers:

The balloon is at 1000 feet.

The balloon drops at a constant speed of -4 1/2 per second.

How long will it take to get to 215ft, in seconds, s.

Lets see, if you were to subtract 1000-215, you will get 785.

The balloon needs to drop 785ft to get to 215ft above the ground.

The question asks how long will it take to get below 215ft.

Lets do the math for the descending feet. We calculated that it takes 785ft to hit 215ft above the ground, so, you need to divide 785ft by 4 1/2 to see how many seconds it takes. The answer for this is 174.4, we can make this 174 4/9.

**VERY IMPORTANT** If you use 174 4/9, this equals 215 seconds, it asks for below this, so you can use ANY number for this that it above this number.

Now for the inequality, look at the question, it asks how long will it take to get below, not equal to or more below, meaning that you can cancel out the inequality signs with lines below them. So your answer is 270 > ,

Please tell me if this is right, if its not let me know I apologize.

What is the value of the expression when c=0 and d=-6 ?

Answer:

-9

Step-by-step explanation:

This what you wrote:

[tex] cd - \dfrac{d^2}{4} = [/tex]

[tex] = (0)(-6) - \dfrac{(-6)^2}{4} [/tex]

[tex] = 0 - \dfrac{36}{4} [/tex]

[tex] = -\dfrac{36}{4} [/tex]

[tex] = -9 [/tex]

Maybe this is what you meant to write:

[tex] \dfrac{cd - d^2}{4} = [/tex]

[tex] = \dfrac{(0)(-6) - (-6)^2}{4} [/tex]

[tex] = \dfrac{-36}{4} [/tex]
