Answer: D(2750) = 637.5

if total sales = $2750 then total donation = $637.5

Step-by-step explanation:

GIven: A local coffee shop has made a flat donation of $500 and also give a percent of their total sales over a specified weekend.

The total donation can be modeled by the function rule D(s)=500+0.05s,

where s = total sales at the coffee shop during the fundraising weekend in dollars.

Now, D(2750) = 500+0.05(2750)

= 500+ 137.5

= 637.5

i.e. if total sales = $2750 then total donation = $637.5

$25.20 for the cranberry juice (see explanation)

Step-by-step explanation:

4 quarts of apple juice and 4 quarts of cranberry juice are the simplest amount I can come up with. Meaning: 4 quarts of cranberry juice being $25.20 mixed with the apple juice.

Given parameters:

Length of the gift box = 8 inches

Width of the box = 3 inches

Height of the box = 4 inches

Unknown :

Length of its longest diagonal = ?

Solution:

This is a rectangular box.

To find the diagonal of such box, let us use the formula below;

             Diagonal  = [tex]\sqrt{l^{2} + w^{2} + h^{2} }[/tex]

l is the length

w is the width

h is the height

Input the parameters and solve;

           Diagonal  = [tex]\sqrt{8^{2} + 3^{2} + 4^{2} }[/tex]   = 9.4inches

The diagonal of the box is 9.4inches

Answer:

Step-by-step explanation:

Since it's a right angled triangle we can use trigonometric ratios to find the value of B

To find the value of B we use cosine

That's

cos∅ = adjacent / hypotenuse

From the question

adjacent = 4

hypotenuse = 5

We have

[tex] \cos(B) = \frac{4}{5} \\ B = { \cos }^{ - 1} ( \frac{4}{5}) \\ = 36.869897645...[/tex]

We have the final answer as

Answer:

Part (i)

Answer:  m/n

--------------------

Explanation:

You divide the total bill over the number of people at the dinner. This leads to the quotient and the amount each person pays (each person pays the same amount).

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

Part (ii)

Answer:  80 dollars

--------------------

Explanation:

Plug in m = 400 and n = 5 to get

m/n = 400/5 = 80

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

Part (iii)

Answer:  m = 7x

--------------------

Explanation:

x = m/n

x = m/7

7x = m ... multiply both sides by 7

m = 7x

The total bill is 7 times of what each person paid.

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

Part (iv)

Answer:  7 people

--------------------

Explanation:

x = 20 is the amount each person paid

m = 140 is the total bill

n = number of people who went to dinner

x = m/n

20 = 140/n

20n = 140 ..... multiply both sides by n

n = 140/20 ..... divide both sides by 20

n = 7

Seven friends went to do dinner, splitting a $140 bill, paying $20 each

Answer:

m/n; $80; 7*x; 7 friends

Step-by-step explanation:

(I) $x=$m/n

(II) $x=400/5=$80

(III) $m=7*x

(IV) n=140/20=7

Answer: 6.5 cm

Step-by-step explanation: 1 km = 100,000 cm, so 130 km= 130,000,00 cm, 130,000,00÷2,000,000=6.5 cm

The Charles river will be "6.5 cm" long. A complete solution is provided below.

On the map,

→ 1 : 2,000,000

As we know,

The conversion of kilometer in to centimeter is:

→ [tex]1 \ km = 100,000 \ cm[/tex]

then,

→ [tex]130 \ km= 130,000,00 \ cm[/tex]

hence,

The river will be:

= [tex]\frac{130,000,00}{2,000,000}[/tex]

= [tex]6.5 \ cm[/tex]

Thus the above answer is the appropriate.

Step-by-step explanation:

Let x=smaller number

Then x+5=larger number

Now we are told the following:

1/5(x+x+5)=x-5 multiply each side by 5

x+x+5=5x-25 subtract 5x and also 5 from both sides

x+x+5-5-5x=5x-5x-25-5 collect like terms

-3x=-30 divide both sides by -3

x=10-----------------------smaller number

x+5=10+5=15 ---------larger number

Answer:

157.5 pages

Step-by-step explanation:

First, find your rate. You want to know how many pages you can read per minute. We can use any nuber, but using 2 minutes will be the simplest solution:

2m = 7

---      ---      <---- Here we divide both sides of the equal sign by 2

2        2

m = 3.5 <---- we read 3.5 pages per minute

45 x 3.5 = 157.5 (We multiplied 45 because it's the number of minutes we have, by the 3.5 pages we read each minute. This gives us our total of 157.5 pages in 45 minutes.

Answer:

The length of one side is 13 feet.

Step-by-step explanation:

To start, a square is 4 sides that are equal in length. This means that when you have a problem like this, you need to set the equations equal to each other like:

[tex]2x+5=6x-11[/tex]

In order to solve a problem like this, with the same variables on different sides, start by subtracting the smaller variable from both sides. In this case, you would be subtracting 2x from both sides, which would leave us with:

[tex]5=4x-11[/tex]

After that, you solve it like a normal one-step equation. Add 11 to both sides.

[tex]16=4x[/tex]

Now, divide both sides by 4 and you will know how much [tex]x[/tex] is worth.

[tex]4=x[/tex]

Now that we know how much [tex]x[/tex] is worth, we can plug that into either of the equations given to us. It doesn't matter which since they are equal to each other.

[tex]2(4)+5[/tex]

That would give us 13.

Answer:

the sides are 13

x= 4

Step-by-step explanation:

2x+5 = 6x-11     subtract five from both sides

2x = 6x-16        subtract 6x from both sides

-4x = -16           divide both sides by -4

x = 4                substitute into original problem

2(4) + 5 = 6(4) - 11

8 + 5 = 24 - 11

13 = 13
