I needdddddd hellpppp it’s due TODAYyYYyY

Look up "Everything You Need To Know About Math In One Big Fat Notebook pdf." It's the best thing I've ever been given, I have it with me in math class all the time and I've aced every test.

Answer:

Step-by-step explanation:

-4=2x+16

-16. -16

-20=2x

20/2=2x/2

10=x

Answer:

A and D and E

Step-by-step explanation:

Substitute the variable(in this case) t for 3, then use the order of operations to simplify(PEMDAS), which will give you 33 for both expressions. To see if two expressions are equivalent, you need to substitute the variable for an odd number AND an even number, so next, substitute the variable t for the number 6, which will give you 51 for both expressions. That means the expressions are equivalent

Hope this helps :)

P.S. Mark brainliest pls

Answer:

Step-by-step explanation:

Given expressions:

The value of both expressions when t=3 is 33.

The value of both expressions when t=3 is 23.

The value of both expressions when t=6 is 41.

The value of both expressions when t=6 is 51.

The two expressions are equivalent.

The two expressions are not equivalent.

The answer is c and the second part im not sure

Answer:

The 3rd option is correct

Step-by-step explanation:

Answer:

130°

Step-by-step explanation:

Using the formula

Area of the triangle = 1/2 absin theta

a and b are the sides

theta is the obtuse angle

Given

a = 30m

b = 26m

Area = 200m²

Required

theta

Substitute into the formula;

300 = 1/2(30)*(26)sin theta

300 = 15*26sin theta

300 = 390 sintheta

sin theta = 300/390

sin theta = 10/13

sin theta = 0.7692

theta = arcsin(0.7692)

theta = 50.28degrees

Since the angle is obtuse, it must lie between 90 and 180degrees

theta = 180-50.28

theta = 129.72°

Hence the measure of the obtuse angle to the nearest degree is 130°

so.......

y=20underroot 3

and X=20

Answer:

A triangles angle always equal to 180 degrees. So if you add up what you already have which is 80+40=120

Answer:

1. The Pacific Ocean has an area of 63.78 million square miles, an average depth of 3,688 meters, and a volume of 660,000,000km cubed.

2. Use these guidelines when developing questions:

   Plan your questions.

   Know your purpose.

   Open conversation.

   Speak your listener's language.

   Use neutral wording.

   Follow general questions with specific ones.

   Focus your questions so they ask one thing at a time.

   Ask only essential questions.

Answer:

39600 words

Step-by-step explanation:

Given data

In 1 minute, Alex can type 44 words

from 10:00 AM until 1 AM= 15 hours

15 hours to minutes= 15*60= 900 minutes

Hence in In 1 minute, Alex can type 44 words

            in  900 minutes he will type x words

cross multiply

x= 900*44

x= 39600 words

Hence he will type 39600 words

the answer

y/x so its 9/5

Answer:

[tex]\frac{8}{\left(-x+2\right)^2}[/tex] & [tex]x = 1, x = 3[/tex]

Step-by-step explanation:

I'm sure you are familiar with the product rule,

If y = u*v => dy/dx = u * dv/dx + v * dy/dx <----- product rule

In this case:

[tex]u=3x+2,\:v=\left(2-x\right)^{-1},\\=>\frac{d}{dx}\left(3x+2\right)\left(2-x\right)^{-1}+\frac{d}{dx}\left(\left(2-x\right)^{-1}\right)\left(3x+2\right)[/tex]

Now remember the sum rule:

[tex]\frac{d}{dx}\left(3x+2\right) = \frac{d}{dx}\left(3x\right)+\frac{d}{dx}\left(2\right),\\\frac{d}{dx}\left(3x\right) = 3,\\\frac{d}{dx}\left(2\right) = 0\\\frac{d}{dx}\left(3x+2\right) = 3[/tex]

For this second bit we apply the chain rule:

[tex]\frac{d}{dx}\left(\left(2-x\right)^{-1}\right) = -\frac{1}{\left(2-x\right)^2}\frac{d}{dx}\left(2-x\right),\\\frac{d}{dx}\left(2-x\right) = -1,\\\\=> -\frac{1}{\left(2-x\right)^2}\left(-1\right)\\=> \frac{1}{\left(2-x\right)^2}[/tex]

If we substitute these values back into the expression...[tex]\frac{d}{dx}\left(3x+2\right)\left(2-x\right)^{-1}+\frac{d}{dx}\left(\left(2-x\right)^{-1}\right)\left(3x+2\right)[/tex]

...we get the following:

[tex]3\left(2-x\right)^{-1}+\frac{1}{\left(2-x\right)^2}\left(3x+2\right)[/tex]

The rest is just pure simplification:

[tex]3\left(2-x\right)^{-1}+\frac{1}{\left(2-x\right)^2}\left(3x+2\right)\\= \frac{3}{-x+2}+\frac{3x+2}{\left(-x+2\right)^2}\\= \frac{3\left(-x+2\right)}{\left(-x+2\right)^2}+\frac{3x+2}{\left(-x+2\right)^2}\\\\= \frac{3\left(-x+2\right)+3x+2}{\left(-x+2\right)^2}\\\\= \frac{8}{\left(-x+2\right)^2}[/tex]

Now let's equate this to equal 8 for the second bit and solve for x:

[tex]\frac{8}{\left(-x+2\right)^2}=8,\\\frac{8}{\left(-x+2\right)^2}\left(-x+2\right)^2=8\left(-x+2\right)^2,\\8=8\left(-x+2\right)^2,\\\left(-x+2\right)^2=1,\\x = 1, x = 3[/tex]

Answer: $‭176.4‬0

Step-by-step explanation:

Keith mowed the yard 12 times.

Each time he mowed took 1.75 hours.

The number of hours he took in total is therefore:

= 12 * 1.75 hours

= 21 hours

He gets paid $8.40 for every hour he works. For the 21 hours therefore, he would earn:

= 8.40 * 21 hours

= $‭176.4‬0

Answer:

It will not fit.

Step-by-step explanation:

The mat is 1/2 by 2/3. So, lets add that together.

1/2 + 2/3 = 7/6

Now there are 24 sixths in a fourth.

So subtract 24 - 4 = 17

Final answer would be 17/4. Still way to big to fit in the 1/4 step.

30/x

Step-by-step explanation:

rsm

================================================

Explanation:

We'll only focus on points J and K.

J = (3, -6)

K = (-1, -6)

Because these two points have the same y coordinate (which is -6), this means we can ignore those values and subtract the x coordinates

3 minus (-1) = 3 - (-1) = 3 + 1 = 4

Or we could plot points J and K on the same xy grid system, and count out the number of spaces between J and K. You should count out 4 spaces.

This means segment JK is 4 units long.
