Answer:

Use PEMDAS

Step-by-step explanation:

Parenthesis, If there are none move on to exponents if there are no exponents move to multiplication. No multiplication? use division. If you dont see division use addition and lastly if there is no addition use subtraction. In the equation, it looks like you have to make the -3 and 8 positive. So, since the -4 is in the parenthesis(P) multiply(M) 4 by 3 and 8 once the three is positive. So your final answer would be either C or D

Its the best i could do but good luck. I tried...

Answer:

Add -3+8

Step-by-step explanation:

You would do this first because it is in the brackets. Usually you would do (*) first but those are just there because the 4 is negative and if they were not there it would get confusing and look like this::[-3+8]--4. So the next step would be the [*].

HOPE THIS HELPS!!!

A salesman’s commission on a 150,000 sale is 3,000. What percent is commission

Tasya [4]

Okay, so we need to make a proportion:

$\frac{3000}{150000}$ $\frac{x}{100}$

We multiply:

3000 x 100 = 300,000

Then we divide:

300,000 / 150,000 = 2

So, the answer would be 2%

I hope this helps! :)

100 pts. & will give brainliest! answer asap

Zanzabum

First we need to differentiate y

$\\ \sf\Rrightarrow \dfrac{dy}{dx}$

$\\ \sf\Rrightarrow \dfrac{d}{dx}(-16x^2-110x+15)$

$\\ \sf\Rrightarrow -32x-110$

Now let it be 0

$\\ \sf\Rrightarrow -32x-110=0$

$\\ \sf\Rrightarrow -32x=110$

$\\ \sf\Rrightarrow x=|110/-32$

$\\ \sf\Rrightarrow x=3.44s$

Put it in y

$\\ \sf\Rrightarrow y=15-110(3.44)-16(3.44)^2$

$\\ \sf\Rrightarrow y=204.05ft$

Please help me due today i really need to pass

Answer:

1) 45 degrees

2) 75 degrees

3) 37 degrees

4) 43 degrees

5) 137 degrees

Step-by-step explanation:

1) Angle 1 is equal to the 45 degree angle above it, so we know it is 45 degrees

2) All triangles are 180 degrees. Angle 2 = 180 - 60 - Angle 1 = 180 - 60 - 45 = 75

3) These three angles = 180 degrees. 180 - 68 - Angle 2 = 180 - 68 - 75 = 37

4) All triangles are 180 degrees. 180 - 100 - Angle 3 = 180 - 100 - 37 = 43

5) 180 - Angle 4 = 180 - 43 = 137
