Hey there!
Let's do this step by step:

1. P-13=2  -------Write out the equation

2. P-13+13=-2+13  ------- Undo the operations

3. \frac{p}{1} = \frac{11}{1}  ------- What you get

4. P=11

Eight out of 21 instruments in the band are woodwinds. If there are 63 instruments in the band, how many more are not woodwinds
Zepler [3.9K]

I don't think you need to do anything special for this question. But do be careful how you read it.

Total number of instruments = 63

Number of woodwinds = 21

Number of non woodwinds = 63 - 21 = 42 non woodwinds.

What you have to be careful about is that this is not the answer.

It says how many more .... So now you have to do another subtraction.

Total number more = Number of non woodwinds - woodwinds.

Total number more = 42 - 21

Total number more = 21 <<<< Answer

3x+4y =-5<br> 3x+3y=-2<br><br> solve using substitution
galben [10]
3x + 4y = -5 
-3x              -3x

4y= -3x -5
/4      /4

y= -3/4x-5/4

3x + 3y = -2
-3x             -3x

3y = -3x-2
/3       /3

y= -1x-2/3

A ball is thrown upward with an initial velocity of 60 mph. it is thrown from a height of 5 feet. what is the maximum height it
natima [27]

Answer:

h = 61.25 m

Step-by-step explanation:

It is given that,

The initial velocity of the ball, v = 60 m/s

It is thrown from a height of 5 feet, h_o=5\ ft

We need to find the maximum height it reaches. The height reached by the projectile as a function of time t is given by :

h=-16t^2+vt+h_0

Putting all the values,

h=-16t^2+60t+5 .....(1)

For maximum height, put

\dfrac{dh}{dt}=0\\\\\dfrac{-16t^2+60t+5}{dt}=0\\\\-32t+60=0\\\\t=\dfrac{-60}{-32}\\\\t=1.875\ s

Put t = 1.875 in equation (1)

h=-16(1.875)^2+60(1.875)+5\\\\h=61.25\ m

So, the maximum height reached by the ball is 61.25 m.
