for a fundraising campaign, a club has a choice of buying products for $20 plus 50% of the sales or $100 plus 25% of the sales. For what level of sales would the club have to pay the same total with either deal?
Answer:
Step-by-step explanation:
20 plus .5x = 100 plus .25x
.25x=80
x=320.
An equation is formed of two equal expressions. The level of sales for which the club have to pay the same total with either deal is $320.
What is an equation?An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
Let the level of sales be represented by x, and the total amount to be paid be represented by y. Therefore, for the first option, the equation can be written as,
y = 20 + 0.5x
Also, For the second option, the equation can be written as,
y = 100 + 0.25x
Now, the level of sales for which the club have to pay the same total with either deal can be found by computing the equation with each other. Therefore,
20 + 0.5x = 100 + 0.25x
0.5x - 0.25x = 100 - 20
0.25x = 80
x = 320
Hence, the level of sales for which the club have to pay the same total with either deal is $320.

What is the slope of the line passing through the given points 4,2 and -2,1
Answer:
Alright, here is the formula.
m = (y2 -- y1) / (x2 -- x1)
So, now we have to take the points and replace them with the variables.
m = (1 - 2) / (-2 - 4)
Great! So now, we have to solve.
1 - 2 = -1
-2 - 4 = -6
So now, it would be:
-1/6
That is the slope! Hope this helps! :)

Write the equation of the line that is perpendicular to the y-axis and passes through the point (-4, 5).
Explanation:
The y axis is vertical. Anything perpendicular to this is horizontal.
All horizontal linear equations are of the form y = k, where k is any number.
In this case, k = 5 so that the line y = 5 goes through all points with y coordinate 5. Two points on this line are (-4,5) and (1,5).
Note how y = 5 is equivalent to y = 0x+5. We see the slope is 0 and the y intercept is 5. Compare this to y = mx+b.

full answer is needing pls with steps!
Answer:
1/8
Step-by-step explanation:
First, take 3/4 and make a common denominator with 3/8. You can make 3/4 into 6/8. Now, subtract 3/8 from 6/8 which is 3/8.
Second, find the common denominator between 3/8 and 1/2. You can make 1/2 into 4/8.
Third. Now subtract 3/8 from 4/8. You get 1/8.
The answer therefore is 1/8

You are Miguel Cervantes de Navas y Colon, captain in the Royal Spanish Army in Sevilla in the year 1842. Outside your barracks window is a stack of cannonballs, as shown in the illustration. On an idle afternoon you decide to calculate the number of cannonballs in the stack. What is the number of cannonballs?
In Sevilla in the year 1842, you are Miguel Cervantes de Navas y Colon, a captain in the Royal Spanish Army. The total number of cannonballs in the stack is 385.
Given that,
In Sevilla in the year 1842, you are Miguel Cervantes de Navas y Colon, a captain in the Royal Spanish Army.
A pile of cannonballs is seen outside the window of your barracks.
The total number of cannonballs can be calculated using the steps below:
The following is a general formula to determine how many cannonballs are altogether in the stack:
Total number of cannonballs is n(n+1)(2n+1)/6
where "n" represents the overall number of layers.
Change the value of "n" in the formula above.
1st layer is stack of cannonballs is 1²=1 cannonball.
2nd layer is stack of cannonballs is 2²=4 cannonballs.
3rd layer is stack of cannonballs is 3²=9 cannonballs.
last layer is stack of cannonballs is 10²=100 cannonballs.
n is 10.
Substitute in the formula
=10(10+1)(2×10+1)/6
=10×11×21/6
=385
Therefore, the total number of cannonballs in the stack is 385.

A packaging company is planning is in the planning stages of creating a box that include a three dimensional support inside the box.The box has a width of 5 feet a length of 6 feet and a height of 8 feet. How long will the diagonal support need to be
Answer:
The length of the diagonal support is 69 feet.
Step-by-step explanation:
Dimensions of the box: length = 6 feet
width = 5 feet
height = 8 feet
The diagonal support relates with the diagonal of the base and the height.
From the base of the box, let the length of its diagonal be represented by x. Applying Pythagoras theorem;
[tex]/Hyp/^{2}[/tex] = [tex]/Adj 1/^{2}[/tex] + [tex]/Adj 2/^{2}[/tex]
[tex]x^{2}[/tex] = [tex]6^{2}[/tex] + [tex]5^{2}[/tex]
[tex]x^{2}[/tex] = 36 + 25
= 61
x = [tex]\sqrt{61}[/tex]
= 7.81
let the length of the diagonal support be represented by l. So that;
[tex]/Hyp/^{2}[/tex] = [tex]/Adj 1/^{2}[/tex] + [tex]/Adj 2/^{2}[/tex]
[tex]l^{2}[/tex] = [tex]x^{2}[/tex] + [tex]8^{2}[/tex]
= [tex]\sqrt{61}[/tex] + 64
l = [tex]\sqrt{\sqrt{61} + 64 }[/tex]
= 61 + 8
= 69
Thus, the length of the diagonal support is 69 feet.
Colin and Brian were playing darts. Colin scored 141. Brian scored 154 more than Colin. What was their combined score?
Answer:436
Step-by-step explanation:
Since Colin scored 141 and Brian scored 154 more than Colin that would be (154+141). So Brian scored 295, so you add Brian's score and Colin's so 295+141, the total score is 436
