The polynomial 40p + 50f + 90 represents the amount of ink, in milliliters, of printing "p" poster and f flyers in
colour. The polynomial 15p+20f + 45 represents the amount of ink, in milliliters, of printing "p" poster and f flyers
in black and white.
How much ink is saved (HINT: use subtraction) if someone prints 26 posters and 45 flyers in black and white rather
than in colour?
ongle below. Then determine the area when
color : 40p + 50f + 90
b&w : 15p+20f + 45
p = 26
f = 45
[substitute the values given]
color : 40(26) + 50(45) + 90
b&w : 15(26)+20(45) + 45
[solve the equation]
color : 3380
b&w : 1335
[subtract to see how much ink is saved]
3380 - 1335 = 2045

At her sisters birthday party Cheyenne thought it would be funny to drink lemonade from a party hat if the radius is 4.8 cm and the height of a hat is 12 cm how many cubic centimeters of lemonade can Cheyenne pour into the hat
92.16 pi cm^3.
Step-by-step explanation:
Shape of a party hat : conical
Volume of a cone = (1/3)(pi)(r^2)(h)
(pi(1/3)(23.04)(12))cm^3
Therefore, approximately
92.16 pi cm^3.
Question 17
Consider the equation y = 15 - 4x.
Which of the following is a graph of this equation?
The graph of the given linear equation is the one that you can see below.
How to get the graph of the linear equation?
To graph lines, we need to get two points on the line. To get the points, we can evaluate the line in two different values of x. Here I will use x = 1 and x = 0.
For x = 0 we have:
y = 15 - 4*0 = 15
So we have the point (0, 15).
For x = 1 we have the point:
y = 15 - 4*1 = 11
So we have the point (1, 11).
Now we need to graph these two points and connect them with a line, you will get the graph that you can see below.

It’s been a while since I did Math but, in most scenarios, when you solve for an equation with only 1 x variable and you substitute it back in, it should always be true and equal the answer in the original equation(?).
For this equation, the answer was x=7, but when I substitute it back in, I was unable to get the original solution back, which means it is “no solution” after all.
Why is that?
Let's replace every copy of x with 7 and simplify.
[tex]\sqrt{5x+1}+9 = 3\\\\\sqrt{5*7+1}+9 = 3\\\\\sqrt{35+1}+9 = 3\\\\\sqrt{36}+9 = 3\\\\6+9 = 3 \ \text{ .... note the 6 on the left isn't negative}\\\\15 = 3\\\\[/tex]
Which is clearly false. This is probably the set of steps you followed to get "no solution".
Why is there no solution? Well let's subtract 9 from both sides to isolate the square root
[tex]\sqrt{5x+1}+9 = 3\\\\\sqrt{5x+1}+9-9 = 3-9\\\\\sqrt{5x+1} = -6\\\\[/tex]
Recall that the result of a square root operation is never negative. The range of [tex]y = \sqrt{x}[/tex] and [tex]y = \sqrt{5x+1}[/tex] is the set of nonnegative numbers. There is no way we can have the left hand side result in -6
If there was a negative sign out front the square root and we have this instead
[tex]-\sqrt{5x+1}+9 = 3\\\\[/tex]
then the answer would be x = 7
Unfortunately, there isn't such a negative sign, so we stick with "no solutions".

The theoretical probability that applesauce and broccoli will both offered on monday is 20%.
What is combination?A combination is a way of selecting items from a collection where the order of selection does not matter. It is calculated by
[tex]^{n} C_{r} = \frac{n!}{(n-r)!}[/tex]
Where,
[tex]^{n} C_{r}[/tex] is the total number of combinations.
n is the total number of objects
r is the number of objects selected.
What is theoretical probability?The theoretical probability is defined as the ratio of the number of favourable outcomes to the number of possible outcomes.
According to the question.
There are total 6 dishes.
Manger have to choose three dishes for monday.
Now the total number of combination of selecting 3 dishes from 6 dishes
[tex]=^{6} C_{3}[/tex]
[tex]= \frac{6!}{3!(6-3)!}[/tex]
[tex]= \frac{6\times5\times4\times3!}{3\times2\times1\times3!}[/tex]
[tex]=20[/tex]
So, the manager has total 20 choices to select three dishes randomly out or 6 dishes.
Also, it is given that for monday applesauce and broccolli will both offered so the number of choices or combination or the three dishes will be
Applesauce, broccoli, and cornapplesauce, brocolli, and dumplingsapplesauce, brocolli, and egg rollsapplesauce, brocolli, and french friesTherefore, the theoretical probability that applesauce and brocoli will both be offered on monday
[tex]= \frac{4}{20}\times100[/tex]

Step-by-step explanation:
an open (empty) point means the point itself is not included.
