If Janelle has 8 nickels in her coin purse, what is the total value of the coins?

a. 52 cents
b. 50 cents
c. 48 cents
d. 46 cents

Answers

Answer 1
The answer is 50 cents. Why? Well, when there’s 6 nickels (which make up 30 cents), there is a total of 40 cents. I noticed this pattern throughout all of the relationships. The total amount of coins is usually 10 cents more than how much the amount of nickels are worth. So, by using this strategy, we will find that there is 50 cents because 8 nickels is equal to 40 cents, which we can find by multiplying 8 by 5 since each nickel is worth 5 cents. The amount of nickels makes up 90% total of the quantity of coins altogether. Because 8 multiplied by 5 equals 40, we can add 10 to find that our total value of coins is 50 cents.

Your final answer: Your answer is B. If you need help, let me know and I will gladly assist you.

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

Substituting the values in the equation , we get

A = ( √14 - √3 ) ( √12 + √7 )

On simplifying , we get

A = √14 ( √12 ) - √3 ( √12 ) + √14 ( √7 ) - √3 ( √7 )

A = √168 - √36 + √98 - √21

On further simplification , we get

A = 2√42 - 6 + 7√2 - √21

Therefore , the value of A is 2√42 - 6 + 7√2 - √21

Hence , the product is A = 2√42 - 6 + 7√2 - √21

Step-by-step explanation:

The three angles added together form a circle, which is 360 degrees

We want to find the sum of k+i, so we subtract 70 from each side

k+i + 70-70 = 360-70

Triangle A B C has centroid G. Lines are drawn from each point through the centroid to the midpoint of the opposite side to form line segments A F, B D, and C E. The length of line segment A G is 19 x + 14 and the length of line segment D G is 9 x + 2.

G is the centroid of triangle ABC.

What is the length of GF?

units

Answers

Based on the calculations, the length of GF is equal to 26 units.

How to find the length of GF?

In Geometry, the centroid of any triangle always divides the lines in a ratio of 2:1. Thus, G divides line B F as follows:

2DG = BD

2(9x + 2) = 40

18x + 4 = 40

18x = 40 - 4

x = 36/18

x = 2.

Similarly, G divides line A F as follows:

2GF = A F

GF = A F/2

GF = (19x + 14)/2

GF = (19(2) + 14)/2

GF = 52/2

GF = 26 units.

Assume that all conditions are met. The mean of the differences was 1. 33 and the standard deviation of those differences was 2. 90. What is the test statistic for this procedure?.

Answers

The test static used for this procedure is Aspin Welch's t-test.

What is Aspin Welch's T-test?

A variation of the Student's t-test used to determine if two sample means are substantially different is known as the Aspin Welch's T - test for Unequal Variances (also known as Welch's t-test, Welch's adjusted T, or unequal variances t-test). The test's degrees of freedom have been changed, which generally boosts the test's power for samples with unequal variance.

The means being equal is the test's null hypothesis.The notion that the means are not equal serves as the test's alternate hypothesis.

Formula for Aspin Welch's T - test

The t-statistic in Aspin Welch's T-test is given as,

t = [tex]\frac{X' - X}{\sqrt{\frac{S1^{2} }{N1^{2} } -\frac{S2^{2} }{N2^{2} } } }[/tex]

Here, X' is the mean of the sample

X is the mean of the population

S1 and S2 are the respective standard deviations for the two samples

N1 and N2 are the respective strength of samples.

Calculating t-statistic for Aspin Welch's T-test

Given that,

X'-X = 1.33

[tex]\sqrt{\frac{S1^{2} }{N1^{2} } -\frac{S2^{2} }{N2^{2} } } = 2.90[/tex]

∴ t = 1.33/2.90

In the equation y=kx, where k is a constant. when y=12, then x=5. when y=60, what does x equal?

Answers

Answer:

If y = 60 then x = 25

Step-by-step explanation:

You know that when y = 12 then x = 5

So when y = 60, x = 25

The reason for this is because 12 * 5 = 60.

Which means that since the y = 12 was multiplied by 5, the x = 5 should be multiplied by 5 too.

Since 5 * 5 = 25, then we know that if y = 60, then x will equal 25.

Write a system of equations that represent the total fees charged for each plan. How many visits does it take before the plans are equal? Separate your equations and final number of visits by comas

Answers

The system of equation is y = 300 + 3x and y = 250 + 5x and  the number of visits is 25

The system of equations

The given parameters are:

Jim's Gym

Initial fee = $300Charges = $3 per visit

Sally's Salon

Initial fee = $250Charges = $5 per visit

The equation is calculated as:

Total (y) = Initial * Charges * Number of visits (x)

So, the system of equation is

y = 300 + 3x

y = 250 + 5x

Number of visits before the plans are equal

We have:

y = 300 + 3x

y = 250 + 5x

Substitute y = 300 + 3x in y = 250 + 5x

300 + 3x = 250 + 5x

Evaluate the like terms

-2x = -50

Divide by -2

x= 25

help me please eeeeeeeeee

Answers

Answer:

A

Step-by-step explanation:

Fundamental Theorem of Algebra:

   This states that any polynomial with degree n will have n solutions which are real or complex.

Since this function you gave has 4 zeroes, this function has to have at at least a degree of 4. The reason I say at least, is because of something called multiplicity. When a zero has an even multiplicity it will have a turning point at the zero, if it has an odd multiplicity it will pass the x-axis. So assuming each zero only has a multiplicity of 1, then this will have at least a degree of 4. It also might have complex zeroes which still count as zeroes.

End Behavior of Polynomial Functions:

   So this is pretty easy to remember, but if the leading coefficient is positive, then the end behavior to the right will go up, if it's negative it will go down. Now the next thing to know is an odd degree means that the end behavior will go in opposite directions. So if the right goes up, then the left side will be going down and vice verse. if it's an even degree then the two opposite sides will go in the same direction.

In this case both ends are going down, in the same direction. This means that the leading coefficient is negative and the degree is even.

Using these two things, we can exclude answers

B can't be the answer, it only has 3 zeroes, this has at least 4.

C can't be the answer, it has an odd degree so the end behaviors would go in opposite directions

D can't be the answer, it has a positive leading coefficient so the right side would be going up

This means the only possible equation is A which has at least a degree of 4, negative leading coefficient, and even degree.
