Answer:

Q4) 256 roses

Q5) 40 hamburgers

Q6) 60 professors and 168 lecturers

Q7) 20 percussionist on the sideline

Step-by-step explanation:

Q4) First to set up a proportion you simply have to write a letter to represent the missing number. In this case we'll be using x. So it'll look something like these:

I) 160:5 = x:8 (using colon) or

II) 160/5 = x/8 (as two equal fractions)

You can use one of the two above.

I used the fractions here to solve the question.

After setting up the proportion, your going to cross multiply to get the value of x so its going to look like this:

160×8 = 5×x

1280 = 5x

5x = 1280

Now you have to divide on both sides to isolate x.

5x÷5 = 1280÷5

x = 256

Therefore your answer is 256 roses.

Q5) Use the same method in Q4.

Q6) This is where the proportion using colon comes in. It should look like this 5:14. 5 representing the professors and 14 the lecturers. Now it said that the total number of faculty members is 228.

First thing your going to do is add the proportion together. So basically 5+14=19.

After acquiring this your going to use the sum to divide the total number of faculty members which is 228. So 228÷19=12.

And finally you now have to multiply both sides of the proportion by 12. Therefore 5×12:14×12

60:168

To make sure the answer is right add the proportions of the working above which will give you the total number of faculty members. 60+168=228.

Your final answer: There are 60 professors and 168 lecturers.

Q7) Use the same method done in Q6.

I gave the answers to questions 5 and 7 because I wanted to give you the opportunity to try out the working outs yourself for a better understanding on your part and see if you can get the same answers as me. Anyway hope this helped.

qm = A - D

q =(A-D) /m

Answer:

q = (A - D)/m

Step-by-step explanation:

A = D + qm

A - D = qm

(A - D)/m = q

So, the solve for q is q = (A - D)/m

Answer:

B) 4,1,3,2

Explanation:

Michele's credit cards have the following balances and APR

Credit Card         Balance       APR

     #1                 $4,380          17%  

     #2                $1,365          19%

     #3                $2,480         23%

     #4                $5,000         15%

If she wants to start paying them off one at a time depending on their balance, she could start by paying the credit card with the highest balance, then continue with the second highest balance and so on. She would pay first her credit card #4, then #1, #3 and finally #2.

Answer:

w=-8.6 is your answer

-5w-43. is the simple version

Step-by-step explanation:

First distrubute the -7 and set equal to 0 so that we can move the w to the other side.

-7w-28+2w-15=0

-5w-43=0

add 43 to both sides so you can slove for w

-5w=43

divide both sides by -5 to isolate the w

w=-8.6

[tex]-15[/tex]

Step-by-step explanation:

We can factor out a 1 from -3 to get [tex]5\cdot(-3)=5\cdot-1\cdot3=-1(5\cdot3)[/tex].

We know from simple arithmetic that [tex]5\cdot3=5+5+5=10+5=15[/tex].

So, our answer is [tex]-1(15)=\boxed{-15}[/tex]

Answer:

The product of 5 and 3 is 15.

Statement: The product of a positive and a positive is a positive.

Step-by-step explanation:

5 x 3 = 15

d.) .7107

e.) .2185

:)

Step-by-step explanation:

185 is to 14.8 as x is to 18.5

185/14.8 = x/18.5

x = 185(18.5)/14.8

x = $231.25

Answer:

Step-by-step explanation:

Refer to attached picture. Not to scale.

The picture explains all the given parameters.

We need to find the distance d, which is the sum of x and y.

First convert minutes to degrees:

Find x:

Find y:

The distance between the planes:

The maximum distance is the diameter of the circle, which is of 44 units.

The equation of a circle of radius r and center [tex](x_0,y_0)[/tex] is given by:

[tex](x - x_0)^2 + (y - y_0)^2 = r^2[/tex]

In this problem, the circular path is modeled by:

[tex]x^2 + y^2 - 10x - 18y - 378 = 0[/tex]

We complete the squares to place it in the standard format, thus:

[tex]x^2 - 10x + y^2 - 18y = 378[/tex]

[tex](x - 5)^2 + (y - 9)^2 = 378 + 25 + 81[/tex]

[tex](x - 5)^2 + (y - 9)^2 = 484[/tex]

Thus, the radius is:

[tex]r^2 = 484 \rightarrow r = \sqrt{484} = 22[/tex]

Then, the diameter is:

[tex]d = 2r = 2(22) = 44[/tex]

The maximum distance is the diameter of the circle, which is of 44 units.
