1.Mary has ( 20xy - 10x²) sweets. She wants to divide the sweets equally among her (5x) friends.
if X=6 and Y=4, how many sweets:
will she give to each friend?
Answer:
4
Step-by-step explanation:
The number each friend will get is the total number divided by the number of friends:
(20xy -10x²)/5x = (4y -2x) = 2(2y -x)
__
For x=6 and y=4, the number each friend will get is ...
2(2×4 -6) = 2(2) = 4
Mary will give 4 sweets to each friend.

Answer:
15/2
Step-by-step explanation:
If you need to simplify it/it can't be a decimal then 15/2 would be your answer.
Work:
30/4 = 7.5 (decimal)
15 times 2 = 30 (15 goes into 30 twice evenly)
15/2 is the simplest you can make it without it being uneven.
15/2

Bag of tulips = $ 7
Step-by-step explanation:
Given :

Step-by-step explanation:
when picking (ahem, buying) a soccer ball, there are 75 total possibilities.
the chance to pick a bad one is then
4/75 = 0.053333333...
now we are buying 3 balls out of the 75.
how many possible options do we have ?
picks cannot be repeated, and the sequence does not matter, so we need combinations :
C(75,3) = 75! / (3! × (75-3)!) = 75×74×73/(3×2) = 25×37×73 =
= 67,525 possible groups of 3 balls.
from all these possibilities, how many have 2 good and 1 bad ball ?
as many as options we have to pick 2 balls out of 71 and 1 out of 4 :
C(71,2) × C(4,1) = 71! / (2 × (71-2)!) × 4! / (1 × (4-1)!) =
= 71×70/2 × 4 = 71×70×2 = 9,940 possibilities
so, the total probability to buy 2 good and 1 bad ball is
9940/67525 = 1988/13505 = 0.147204739...

Write the standard form of the equation of the line that is perpendicular to y = -x + 12 and contains the
point (-6, -5)
Answer:
y = x + 1
Step-by-step explanation:
Multiply the original by -Ax to find the perpendicular, then the point it lines up with on the y-intercept is so because there is a 1 difference between 5 and 6
the value of n is a distance of 3 units from 1 1/2
Answer:
3
Step-by-step explanation:
Given the question :
The value of n is a distance of 3 units from 1 an 1/2 on a number line click on the number line to the possible values of n
From the context of the expression:
n is the distance which exists between 1 1/2 and 3 units from it;
Which may be ;
1 1/2 - - - - (1 1/2 + 3) = 4 1/2
1 1/2 - - - - - (3 - 1 1/2)
Either way, there exists a distance of 3 units between 1 1/2 and 3 units from it.
Hence, n = 3
-9x+2x+32=-10 The solution for X
Answer: x = 6
Step-by-Step Explanation:
=> -9x + 2x + 32 = -10
= -7x + 32 = -10
= -7x = -10 - 32 = -42
=> x = -42/-7 = 42/7 = 6
Therefore, x = 6

-9x+2x+32=-10. what is x?
[tex]\dashrightarrow\large\blue\textsf{\textbf{\underline{Answer \& How to solve:-}}}[/tex]
When solving an equation, we need to make sure all variables are on the
left-hand side, and all numbers are on the right-hand side.
There are numbers on both sides, so we need to move all of them to the right.
[tex]\bold{-9x+2x=-10-32}[/tex]
[tex]\bigstar[/tex] On simplification,
[tex]\bold{-9x+2x=-42}[/tex] Next, combine like terms (-9x+2x).
[tex]\bigstar[/tex] On further simplification,
[tex]\bold{-7x=-42}[/tex] Next, divide by -7 on both sides.
[tex]\bigstar[/tex] Which results in
[tex]\bold{x=6}[/tex]
Note:-It's always a good idea to make sure the solution is correct.
We can check that by substituting the value of x (x=6) in lieu of x (into the original equation) and seeing whether or not we have a true statement:-
[tex]\bold{-9(6)+2(6)+32=-10}[/tex]
[tex]\dagger[/tex] On simplification,
[tex]\bold{-54+12+32=-10}[/tex]
[tex]\dagger[/tex] On further simplification,
[tex]\bold{-42+32=-10}[/tex]
[tex]\dagger[/tex] Which results in
[tex]\bold{-10=-10}[/tex]
LHS=RHS, so our solution is indeed correct.
So we conclude that [tex]\boxed{\bold{x=6}}[/tex].

8. A patient in a hospital is given soup daily in a cylindrical bowl of diameter [tex]7 \mathrm{~cm}[/tex] . If the bowl is filled with soup to a height of [tex]4 \mathrm{~cm}[/tex] , how much soup the hospital has to prepare daily to serve 250 patients?
Answer:
38.5 litres soup the hospital has to prepare daily to serve 250 patients.Step-by-step explanation:
As we given that A patient in a hospital is given soup daily in a cylindrical bowl of diameter 7 cm. If the bowl is filled with soup to a height of 4 cm.
So,
Heigth of cylinder = 4 cmDiameter of cylinder = 7 cmRadius of cylinder = 7/2 = 3.5 cm[tex]\bigstar[/tex]To Find Volume of soaps required in the hospital to prepare daily to serve 250 patients. Firstly we need to find The volume of Soap in each bowl for 1 patient.
Using formula:
[tex] \\ \: \: \: \: \dashrightarrow \: \: \: \: \sf \red{\underbrace{Volume_{(Cylinder)} = \pi r^2 h}} \\ \\ [/tex]
On substituting the required values, we get:
[tex] \\ \: \: \: \: \dashrightarrow \: \: \: \: \sf Volume_{(Cylinder)} = \dfrac{22}{7} \times {(3.5)}^{2} \times 4 \\ \\ \\ \: \: \: \: \dashrightarrow \: \: \: \: \sf Volume_{(Cylinder)} = \frac{22}{7} \times 12.25 \times 4 \\ \\ \\ \: \: \: \: \dashrightarrow \: \: \: \: \sf Volume_{(Cylinder)} = \frac{22}{ \cancel{7} } \times{ \cancel{ 49}} \\ \\ \\ \: \: \: \: \dashrightarrow \: \: \: \: \sf Volume_{(Cylinder)} = 22 \times 7 \\ \\ \\ \: \: \: \: \dashrightarrow \: \: \: \: \sf{ \red{ \underbrace{Volume_{(Cylinder)} = 154 \: {cm}^{3}}}} \\ \\ [/tex]
Hence, We have get the volume of soap for 1 patient is 154 cm³.
Now we need to find the volume of soap for 250 patients:
[tex] \\ \: \: \: \: \: \: \dashrightarrow \: \: \: \: \: \: \sf 154 \times 250 \\ \\ \: \: \: \: \: \dashrightarrow \: \: \: \: \: {\red{\underbrace {\sf {38500 \: cm^3}}}} \\ \\ [/tex]
Soap In litres:
1000 cm³ = 1 litre 38500/1000 = 38.5 litres[tex]\therefore[/tex]38.5 litres soup the hospital has to prepare daily to serve 250 patients.

Write a cosine function that has a midline of 2, an amplitude of 3 and a period of 7π/4.
PLS EXPLAIN! THXS!
Answer:
[tex]y=3\cos(\frac{8}{7}x)+2[/tex]
Step-by-step explanation:
Recall
General cosine function: [tex]y=a\cos(bx+c)+d[/tex][tex]|a|[/tex] represents the amplitude, or the distance between the maximum/minimum of the function and the midline[tex]\frac{2\pi}{|b|}[/tex] represents the period, or the length of a cycle of the function which repeats continuously[tex]-\frac{c}{b}[/tex] is the phase shift/vertical shift[tex]d[/tex] is the midline, or the average between the maximum and the minimum, creating a horizontal center lineWe are given that the amplitude is [tex]a=3[/tex] and that the equation of the midline is [tex]d=2[/tex]. Since we know the period to be [tex]\frac{7\pi}{4}[/tex], we need to solve for [tex]b[/tex] by setting up the equation [tex]\frac{7\pi}{4}=\frac{2\pi}{|b|}[/tex]:
[tex]\frac{7\pi}{4}=\frac{2\pi}{|b|}\\\\7\pi b=8\pi\\\\b=\frac{8}{7}[/tex]
Hence, our cosine function will be [tex]y=3\cos(\frac{8}{7}x)+2[/tex]. See the attached graph for a visual.
Alex is standing still and throws a football with a speed of 10 m/s to his friend, who is also standing still. the two friends are standing 5 meters apart. which describes how each person observes the speed of the football? alex observes it as 10 m/s, and his friend observes it as less than 10 m/s. alex observes it as less than 10 m/s, and his friend observes it as 10 m/s. both alex and his friend observe it as 10 m/s. both alex and his friend observe it as less than 10 m/s.
The statement that describes how each person observes the speed of the football is both Alex and his friend observe it as 10 m/s.
To answer the question, we need to know what speed is.
What is speed?Speed is the distance moved per unit time
Since Alex is standing still and throws a football with a speed of 10 m/s to his friend, who is also standing still. If there were relative motion between Alex and his friend, that is Alex or his friend were moving, each person would observe a different speed for the football.
Since there is no relative motion between Alex and his friend, they both observe the same speed for the football.
So, both Alex and his friend observe it as 10 m/s.
So, the statement that describes how each person observes the speed of the football is both Alex and his friend observe it as 10 m/s.

So if the total number of peanuts and raisins in a mix is 84, calculate the number of peanuts of raisins in the mix.
Answer:
60 peanuts and 24 raisins.
Step-by-step explanation:
First work out the divisor which is 5 + 2 = 7.
84 / 7 = 12.
So there are 12 * 2= 24 raisins and 5 * 12 = 60 peanuts.

At first glance, you'll notice that the line is going from left to right which tells us that the slope will be negative therefore the bottom option can be eliminated.
Knowing that the formula for slope is rise over run, you'll notice that the lines rises by -8 and runs by 3 which means that the slope would be -8/3.
