Math problem please help
A student bake sale is selling baked goods. In total they sell 100 pieces of baking, Chocolate chip cookies sell for $0.50 and Muffins for $1.25. The total money earned from the bake sale came to 68.75. How many muffins did they sell?
Please show explanation
Will mark brainlist!
Step-by-step explanation:
Equations:
68.75 = 0.5c + 1.25m
c + m = 100
First, let's get rid of one of the variables. Let's start with the simplest equation first. Let's move a variable, so that only one variable is equal to the rest of the equation.
c + m = 100 to c = -m + 100
(it doesn't matter which variable)
Next, since we have what variable c is equal to, we will now incorporate it into our more complex equation.
68.75 = 0.5(-m + 100) + 1.25 m
Now, to get rid of the parentheses, and just have a regular addition equation with the only variable being m.
68.75 = -0.5m + 50 + 1.25m
Next, we need to make it so that there is only one version of the variables. Just combine the variables together so that the form one cohesive unit.
68.75 = 0.75m + 50
Now, we are going to do the same thing that we did in our first equation (with a mix of the last step we just did), but instead of variables, we are going to do it with the whole numbers instead, and converge them onto one side of the equal sign. Keep in mind that at this step in the process, the variable with it's cohesive unit should be isolated on one side of the equal sign and the other being taken up solely by whole numbers.
118.75 = 0.75m
Now, we just need to make the variable equal to 1 (or just m). So we must either multiply or divide. In this case we will be multiplying both sides by 0.75.
118.75 x 0.75 = 0.75m
So, after this step, you should have an answer of;
89.0625
However, you can't just sell a 0.0625% portion of something to somebody (especially muffins, like come on). Also, the amount of cookies and muffins must be equal to 100 and each variable is in whole numbers (usually).
*Always make sure that when you are done with a problem that you double check it. Usually, with equations like this, you just plug in the variables into the equations, and if they fit both equations, you've done well.
From this point forward, I'm leaving you to your own devices. It's 2:38 a.m. and I need to get up at 7:15. I hope this helps!

Write the equation for the line that has the given slope and contains the given point.
slope = −2
passes through ( 3 , 1 )
Answer:
Step-by-step explanation:
y = mx + b
m = slope
b = y intercept
y and x in the equation represent the coordinate points (3,1)
so substituting,
y = -2x + b
1 = -2(3) + b
1 = -6 + b
b = 7
so the final equation is,
y = -2x + 7
A bouncy ball is dropped such that the height of its first bounce is 6.25 feet and each
successive bounce is 80% of the previous bounce's height. What would be the height
of the 11th bounce of the ball?
Answer:
0.67 feet
Step-by-step explanation:
This question can be interpreted as find the 11th term of a geometry progression where a = 6.25 and r = 80%
So, we have:
[tex]T_n = ar^{n-1}[/tex]
In this case:
[tex]r - 80\% = 0.8[/tex]
[tex]n = 11[/tex]
So, we have:
[tex]T_{11} = 6.25 * 0.8^{11-1}[/tex]
[tex]T_{11} = 6.25 * 0.8^{10}[/tex]
[tex]T_{11} = 6.25 * 0.1073741824[/tex]
[tex]T_{11} = 0.67ft[/tex]
Hence, the height of rebound at the 11th time is approximately 0.67

2x - 5 = 7
Answer:
[tex]x = 6[/tex]Step-by-step explanation:
[tex]2x - 5 = 7 \\ 2x = 12 \\ x = 6[/tex]
Hey there!
“Solve 2x – 5 = 7”
FIRST: ADD both SIDES by 5
2x – 5 + 5 = 7 + 5
CANCEL out: –5 + 5 because it gives you 0
KEEP: 7 + 5 because it helps us solve for x
7 + 5 = 12
NEW EQUATION: 2x = 12
SECOND: DIVIDE both sides by 2
2x / 2 = 12 / 2
CANCEL out 2 / 2 because that gives you 1
KEEP: 12 / 2 because it gives you the value of x
NEW EQUATION; x = 12 / 2
SOLVE ABOVE and you have your answer
12 / 2 = 6
Therefore, x = 6 ☑️
Good luck on your assignment and enjoy your day!

A.
12.4%
B.
24.7%
C.
32.1%
D.
62.3%
Answer: Your answer would be C) 32.1%
Step-by-step explanation:
With the number of successes needed to be 4 and the total amount of trials (games) for this to be achieved in being 6 you can calculate a percentage based on their currenting winning percentage of .623 (don't forget decimals can be percentages, just move the decimal point over) and you can input all of this into the binomial model equation to get your answer. Please do note also that it would be a different answer entirely if you were to use .500 (50%) as a winning percentage which would be the logical conclusion as any team has a 50/50 chance of winning a given game but instead the question is asking us to calculate this percentage off the already given winning percentage. After inputting the data into the model formula you can conclude the answer to be 32.1% chance of them winning 4 out of the next 6 games. I hope this has been of assistance to you :)
Have a wonderful rest of your day!

Delta Airlines' flights from Boston to Seattle are on time 70 % of the time. Suppose 6 flights are randomly selected, and the number on-time flights is recorded. 1.The probability that at least 4 flights are on time is
Answer:
P(at least 4) = 0.74431
Step-by-step explanation:
Here
Probability of the flights on time is = 70% = 70/100= 0.7
q= 0.3
n= 6
As the probability of success and failure is constant and the n is also fixed then the binomail probability distribution can be used to solve this.
P (x= 4) = 6c4 *(0.7)^4 (0.3)^2= 15*0.2401* 0.09= 0.324135
P (x= 5) = 6c5 *(0.7)^5(0.3)^1= 6*0.16807* 0.3=0.302526
P (x= 6) = 6c6 *(0.7)^6 (0.3)^0= 0.117649P
P (x= 0) = 6c0 *(0.7)^0 (0.3)^6= 0.000729
P (x= 1) = 6c1 *(0.7)^1 (0.3)^5=0.010206
P (x= 2) = 6c 2*(0.7)^2 (0.3)^4=0.059535
P (x= 3) = 6c3 *(0.7)^3 (0.3)^3=0.18522
Probability of at least 4 means that probability of greater than 4 inclusive of 4.
This can be obtained in two ways.
First is by subtracting the probabilities of less than 4.
Second is by adding probabilities greater than 4 including 4.
We get the same answer with any of the two methods used.
P(at least 4) = 1- P(x<4)
= 1- [ 0.000729+ 0.010206 +0.059535+ 0.18522]
= 1- 0.25569
= 0.74431
P (at least 4) = P(x=4) +P(X=5) + P(x=6)
=0.324135+ 0.302526+ 0.117649
=0.74431
Find the number of outcomes in the complement of the given event. Out of 246 shoes in a department store, 198 are women's shoes.
Answer:
I suppose that the event here is selecting randomly a shoe.
We know that there are 246 shoes in the store, and 198 of them are women's shoes.
Then there are 246 - 198 = 48 shoes that are not women's shoes.
This means that if the event is something like "finding randomly a women's shoe"
The complement would be "selecting randomly a shoe which is not a women's shoe"
And there will be 48 outcomes that meet this condition.

Five years ago, Mark was twice as old as Max. In three years, Max's age will be 2/3 that of Mark. What is the sum of their ages now
Answer:
4years
Step-by-step explanation:
Let the present age of Mark be x
Let the present age of Max be y
Five years ago
Mark = x-5
Max = y - 5
If mark was twice as old as Max, then;
x - 5 = 2(y-5)
x-5 = 2y - 10
x-2y = -10+5
x - 2y = -5 ... 1
In three years,
mark = x+3
Max = y+3
Now if Max's age will be 2/3 that of Mark, then;
x+3 = 2/3(y+3)
3(x+3) = 2(y+3)
3x + 9 = 2y+6
3x-2y = -3 .... 2
Solve 1 and 2 simultaneously
x - 2y = -5 ... 1
3x-2y = -3 .... 2
From 1: x = -5 + 2y
Substitute into 2:
3(-5+2y) - 2y = -3
-15 + 6y - 2y = -3
-15 + 4y = -3
4y = -3 + 15
4y = 12
y = 3
Recall thet x = -5+2y
x = -5+2(3)
x = -5 + 6
x = 1
The sum of their ages will be x+y
x+y = 1+3
x+y = 4
Hence the sum of their ages now is 4years
[Calculus] particle at rest question. Show steps, please!
Answer:
E
Step-by-step explanation:
We are given that a particle's position along the x-axis at time t is modeled by:
[tex]x(t)=2t^3-21t^2+72t-53[/tex]
And we want to determine at which time(s) t is the particle at rest.
If the particle is at rest, this suggests that its velocity at that time is 0.
Since are we given the position function, we can differentiate it to find the velocity function.
So, by differentiating both sides with respect to t, we acquire:
[tex]\displaystyle x^\prime(t)=v(t)=\frac{d}{dt}\big[2t^3-21t^2+72t-53\big][/tex]
Differentiate. So, our velocity function is:
[tex]v(t)=6t^2-42t+72[/tex]
So, we will set the velocity to 0 and solve for t. Hence:
[tex]0=6t^2-42t+72[/tex]
We can divide both sides by 6:
[tex]0=t^2-7t+12[/tex]
Factoring yields:
[tex](t-3)(t-4)=0[/tex]
By the Zero Product Property:
[tex]t-3\text{ and } t-4=0[/tex]
Hence:
[tex]t=3\text{ and } t=4[/tex]
Therefore, at the 3rd and 4th seconds, the velocity of the particle is 0, impling that the particle is at rest.
Our answer is E.
