Nana76 [90]

Answer:

6 pints of white paint she used to paint her bedroom walls.

Step-by-step explanation:

Joy uses 9.5 pints of blue paint + white paint.

Joy used 3.5 pints of blue paint.

So, white paint used = total paint - blue paint used

Plug in the known values into the equation.

White paint used = 9.5-3.5 =6 pints

Answer:

Step-by-step explanation:

When the population drops by 4.5%, there will be (1 - 4.5%) = 0.955 portion of the original population staying. When it happens 3 years in a row with an original population of 937, there will be:

937*0.955*0.955*0.955 = 816.11

~816 people staying in Bloom Falls.

A baseball team plays in a stadium that holds 62000 spectators. With the ticket price at $11, the average attendance has been 27

sasho [114]

Answer:

$15.625

Step-by-step explanation:

Let the revenue collected be R and price per spectator be p then the number of spectators be N. Therefore

R=Np

Using equation of slope of y=mx +c where m is gradient and c is y-intercept

When p=$11, N=27000 and when p=$8, N=31000

The gradient, m will be

$m=\frac {31000-27000}{8-11}= -1333.33$

To get the y-intercept

N=-1333.33p+c

When spectator number n is 27000, the price p is $11

27000=-1333.33(11)+c hence we solve c

c=27000+(11*1333.33)= 41666.67

Therefore, the linear equation is

N=-1333.33p+ 41666.67

Substituting the linear equation into R=Np we obtain

R=p(-1333.33p+41666.67)

$R=-1333.33p^{2}+41666.67p$

To obtain maximum revenue, we differentiate the above with respect to price hence obtain

0=2*-1333.33p+41666.67

$p=-\frac {41666.67}{2(-1333.33)}= 15.625$

Therefore, the price that maximizes revenue is $15.625

= 7(8n - m ) how do I rewrite this in distributive property?

Natalija [7]

Answer:

56n - 7m

Explanations:

Note that according to the distributive property:

a(b + c) = ab + ac

a(b - c) = ab - ac

Therefore, follow the rule above to rewrite 7(8n - m) using the distributive property.

7(8n - m) = 7(8n) - 7m

7(8n - m) = 56n - 7m
