use this equation for Parts B and A[/tex]
Part C: Given your calculations regarding the volumes in Parts A and B, do you anticipate that Jenny will be able to transport all of the cookie sandwiches in one food storage container? In two or more complete sentences, explain your reasoning.
Answers
volume = PI x r^2 x h
volume = 3.14 x 1^2 x 1.5 = 4.71in^3 = 5 in^3 ( one cookie)
B) container volume = 3.14 x 3.5^2 x 5 = 192.3in^3 = 192 in^3
C) 36 cookies x 5in^3 = 180 in^3
this is less than the volume of the container so they will all fit
Alright to solve it
Part A)
C = 1.5
F =1
You will need to solve it for volume= length times width and times height
3.14 x 1^2 x 1.5
The answer you will get is 5 in^3
Part B) Just do the same proccess as i did on the first one
CV= 192 in^3
Part C)
C=36x5in^3
So this is going to be 180 in^3 because is the less volume.

The networking organization you joined is throwing a party. You are in charge of buying the chips, which cost two dollars and fifty cents per bag and salsa, which costs four dollars per jar. The chips & salsa budget you are given totals $60. The inequality 2.5x + 4y 60 represents the possible combinations of chips (x) and salsa (y) you can buy. graph of the inequality 2.5 x plus 4 y is less than or equal to 60 Which of the following does not represent a solution to the inequality?
Answers
Explanation:
These are the propositions missed:
10 bags of chips and 2 jars of salsa
20 bags of chips and 2 jars of salsa
14 bags of chips and 5 jars of salsa
18 bags of chips and 6 jars of salsa
Solution:
The inequality that you have to graph is:
2.5x + 4y ≤ 60
To graph that you:
1) draw the line 2.5x + 4y = 60
That is the same that:
4y = -2.5x - 60
y = - (2.5/4)x - 60/4
y = -0.625x - 15
That is a line with y-intercept 15 and x-intercpet 15/0.625 = 24.
So, use those two points (0,15) and (24,0) to draw the line.
The sign ≤ implies that the region of solution is below the line (of course in the first quadrant, because x ≥ 0 and y ≥ 0).
The pair (18,6) is not inside the region (it is aboe the line).
You can prove it:
2.5(18) + 4 (6) = 45 + 24 = 69 which is greater than 60, and so it does not fit into the inequality. This is, the money to spend on 18 bags of chips and 6 jars of salsa exceeds the budget of $60. That is why that option is not a solution.

To simplify expressions, one needs to apply rules correctly, such as combining like terms and using exponentiation rules. The process includes correctly applying the rule that simplifies multiplications of the same base by adding their exponents. Cubing exponentials involves multiplying the original exponent by 3.
Explanation:To simplify mathematical expressions, it's crucial to follow the correct rules and operations. In this case, the example provided shows the exponentiation and multiplication rules. Specifically, when dealing with expressions like 3².3⁵, this is equivalent to multiplying 3 x 3 and then taking that result and multiplying it by 3 five more times. According to the rule xPx9 = x(p+q), where x is the base and p and q are the exponents, it simplifies to adding the exponents when the base number is the same and multiplied together.
The process of simplifying expressions involves several steps:
Identifying like terms and combining them.Applying the rules of exponents correctly.Dividing or multiplying to simplify equations as demonstrated with loop equations, dividing by a constant to simplify the equation.Additionally, when cubing exponentials, one should cube the digit normally and multiply the existing exponent by 3, a rule demonstrated in squaring operations as well.

Brenda invests $4,848 in a savings account with a fixed annual interest rate of 5% compounded 2 times per year. What will the account balance be after 6 years?
Answers
She invests some amount in a saving account of fixed interest compounded half-yearly. It says to find its Future Value after six years.
The principal amount is P = $4,848.
Annual interest rate is 5% i.e. r = 0.05
Compounding period is two times per year i.e. n = 2.
Time of investment is t = 6 years.
We know the formula of Future Value is given by :-
[tex] FV=P*(1+\frac{r}{n})^{nt} [/tex]
We can plug the given values in the formula to calculate the answer.
[tex] FV = 4848*(1+\frac{0.05}{2})^{(2*6)} \\\\
FV = 4848*(1+0.025)^{(12)} \\\\
FV = 4848*(1.025)^{(12)} \\\\
FV = 4848*(1.344888) \\\\
FV = 6520.02102 [/tex]
Hence, future value of investment after six years is 6,520.02 dollars.
The question involves calculation of compound interest. The formula to use is A = P (1 + r/n)^(nt), where P is the principal amount, r is the annual interest rate, t is the time in years, n is the number of times interest is compounded per year and A is the amount of money accumulated after n years.
Explanation:This question involves the concept of compound interest. Compound interest is calculated each period on the original deposit, or principal, along with any interest previously earned. Unlike simple interest which only takes into account the principal amount, compound interest accounts for the interest that accumulates on the initial amount as well as the interest that has previously been added.
In Brenda's case, as she's benefiting from compounded interest, the formula to use here is A = P (1 + r/n)^(nt), where P is the principal amount, r is the annual interest rate, t is the time in years, n is the number of times interest is compounded per year and A is the amount of money accumulated after n years.
So, plug in the given values: P=$4848, r=0.05 (as 5% = 5/100), t=6, and n=2 (since it's compounded semi-annually). This will allow us to find the final account balance after 6 years.

Input in standard form the equation of the given line. The line with m=1/2 and b=3
Answers
You are given a slope of m = 1/2 and b = 3. Note that m is used in the slope intercept form of a line, so let's first express this using slope intercept form of for a line, which is y = mx + b.
Plugging in given values you get
y = (1/2)x + 3.
Standard form requires coefficients to be integers, so multiply both sides by 2 to get rid of the fraction.
2y = x + 6
Finally reorder the terms. Subtract both sides by 2y then subtract both sides by 6.
x - 2y = -6
Final answer:
To find the equation of a line with a given slope and y-intercept in standard form, substitute the values of the slope and y-intercept into the equation y = mx + b.
Explanation:
To write the equation of a line given the slope m and y-intercept b in standard form y = mx + b, you can directly substitute the values of m = 1/2 and b = 3 into the equation.
Substitute m = 1/2 and b = 3 into y = mx + b: y = (1/2)x + 3
Therefore, the equation of the line in standard form is y = (1/2)x + 3.
What is the Value of X? Sin(x+22 degree) = Cos( 2x-7 degree) I might have a idea of what it is but I’m not sure
Answers
Hey !!
Check the attachment.
Hope it helps you :)
The value of x in the equation Sin(x+22 degrees) = Cos(2x-7 degrees) can be found by using the identity sin(90° - x) = cos(x), leading to x = 22.67° (or in radians by converting degrees to radians).
To find the value of x in the equation Sin(x+22 degrees) = Cos(2x-7 degrees), we can utilize the trigonometric identity sin(90° - x) = cos(x). By setting the angle inside the cosine to equal 90° - (x + 22°), we can equate this to (2x - 7°) as both represent the same cosine value.
So we have the equation 90° - (x + 22°) = 2x - 7°. Solving for x, we combine like terms: 68° = 3x, which then gives us x = 68°/3. Therefore, x = 22.67°, which is the angle in degrees.
If we needed to find x in radians, we would have to convert degrees to radians by using the conversion factor: π radians = 180°. This would yield x as x = (22.67°/180°) * π.
If you make random guesses for 10 multiple-choice test questions (each with five possible answers), what is the probability of getting at least 1 correct? if a very lenient instructor says that passing the test occurs if there is at least one correct answer, can you reasonably expect to pass by guessing?
Answers
P(X ≥ 1) = 1 - P(X = 0)
This is because the only other option than getting at least one correct is to get nothing correct.
Since there is a 1/5 chance of getting each question correct, there is a 4/5 chance of getting each question wrong:
1 - P(X = 0) = 1 - (4/5)^10 (since there are 10 questions, with a 4/5 chance of missing each one)
= 1 - 0.1073741824 ≈ 0.8926 = 89.26% chance of getting at least one question correct. Given this probability, it is reasonable to expect to pass by guessing.
The probability of getting at least 1 correct answer when guessing on a multiple-choice test can be found by subtracting the probability of getting all answers wrong from 1. Whether it is reasonable to expect to pass by guessing depends on the passing percentage and the probability of getting at least 1 answer correct.
Explanation:To find the probability of getting at least 1 correct answer when making random guesses for 10 multiple-choice test questions, we can look at the probability of getting 0 correct and subtract it from 1. Since each question has 5 possible answers, the probability of getting a question wrong is 4/5. So the probability of getting all 10 questions wrong is (4/5)^10. Therefore, the probability of getting at least 1 correct answer is 1 - (4/5)^10.
To determine if you can reasonably expect to pass the test by guessing, we need to compare the probability of getting at least 1 correct answer to the passing percentage. If the probability of passing is higher than the passing percentage, then it is reasonable to expect to pass by guessing.

2. Find x and y, given that line KL and line MN are parallel. Show all work
Answers
Answer:
[tex]x=9.5[/tex]
[tex]y=8.8[/tex]
Step-by-step explanation:
We have been given a diagram of triangles. We are asked to find the value of x and y.
We can see that triangle JKL and JMN share same vertex that is angle J. Since line KL is parallel to line MN, therefore, there corresponding angles will be equal.
Therefore, Angle-angle-angle similarity [tex]\Delta JKL\sim \Delta JMN[/tex].
Since corresponding sides of similar triangles are always proportional, so we can set a proportion for the sides of our given triangles as:
[tex]\frac{x-2}{5}=\frac{12}{8}[/tex]
Upon cross multiplying our equation we will get,
[tex]8(x-2)=12*5[/tex]
[tex]8x-16=60[/tex]
Let us add 16 to both sides of our equation.
[tex]8x-16+16=60+16[/tex]
[tex]8x=76[/tex]
Let us divide both sides of our equation by 8.
[tex]\frac{8x}{8}=\frac{76}{8}[/tex]
[tex]x=9.5[/tex]
Therefore, x equals 9.5.
We can also set a proportion to solve for y as:
[tex]\frac{y}{22}=\frac{8}{12+8}[/tex]
[tex]\frac{y}{22}=\frac{8}{20}[/tex]
Upon cross multiplying our equation we will get,
[tex]20y=22*8[/tex]
[tex]20y=176[/tex]
Let us divide both sides of our equation by 20.
[tex]\frac{20y}{20}=\frac{176}{20}[/tex]
[tex]y=8.8[/tex]
Therefore, y equals 8.8.
Rachel pays $131.44 for a desk, including tax. The task is 31 cents less than 1*16 the desk’s price. What is the price for the desk before adding the tax?
Answers
Answer:
The cost of the desk is 124 dollars.
Step-by-step explanation:
irst, change this into an equation
tax=1/16x-.31
x equals the cost of the desk without tax:
x+tax=131.44
tax=131.44-x
Set the first equation equal to the second:
1/16x-.31=131.44-x
Solve for x:
17/16x=131.75
x=$124
Hope that helps
The equivalent percentage value for the decimal number 1.16 is 116% which is obtained by multiplying the decimal by 100. Before including the tax the price of the desk was $60.99.
What is percentage?A percentage is a value that indicates 100th part of any quantity.
A percentage can be converted into a fraction or a decimal by dividing it by 100.
And to convert a fraction or a decimal into percentage, they are multiplied by 100.
Given that,
The amount paid by Rachel for a desk is $131.44.
Suppose the price of desk is before adding the tax is x.
Then, as per the problem the following expression can be written for the tax amount as,
1.16x - 0.31
Now, the expression for the price of desk after tax is,
x + 1.16x - 0.31 = 131.44
⇒ 2.16x = 131.44 + 0.31
⇒ 2.16x = 131.75
⇒ x = 131.75 / 2.16
⇒ x = 60.99
Hence, the price for the desk before adding the tax is $60.99.

Answers
In order to find the slope of [tex]f(x)[/tex] we can use the formula:

So, using first two pairs from the given table we have:
[tex]m=\frac{-10-(-15)}{0-(-1)}=\frac{-10+15}{1}=\frac{5}{1}=5[/tex]
Every linear function has the following general look:
[tex]y=mx+b[/tex], where [tex]m[/tex] is the slope of the function.
Applying that general look to our function [tex]g(x)[/tex] we see that it's slope equals 2.
So, we can say that value of [tex]f(x)[/tex] is growing two and half more times faster then value of [tex]g(x)[/tex] as their slopes' ratio is 5:2.
Part B:
The y-intercept of function is it's value in case x is equal 0.
Using the given table we find that the y-intercept of [tex]f(x)=-10[/tex]
As for [tex]g(x)[/tex], let's substitute x value with 0 and solve the equation:
[tex]g(x)=2\cdot0+8=8[/tex]
So, the function [tex]g(x)[/tex] has greater y-intercept then function [tex]f(x)[/tex].

This is the Commutative property of multiplication, which states that two numbers can be multiplied in any order to create the same number.
That tells us that when we're multiplying, it gives us the same value when you multiply two numbers in different orders. Just like here, we have the same numbers, -7/8 and 10, but the difference is they're in different orders, they mean the same thing. For example:
4 *5 = 5* 4
Keep in mind that it doesn't always work with other operations. Observe:
