This question is solved using a system of equations. I am going to say that:

Doing this, we get that: There are 4 nickels and 12 dimes.

There are 8 more dimes than nickels in the bank.

This means that: [tex]y = x + 8[/tex]

There is a total of $1.40.

Thus, for the nickels:

[tex]0.05x + 0.1y = 1.4[/tex]

Since [tex]y = x + 8[/tex]

[tex]0.05x + 0.1(x + 8) = 1.4[/tex]

[tex]0.05x + 0.1x + 0.8 = 1.4[/tex]

[tex]0.15x = 0.6[/tex]

[tex]x = \frac{0.6}{0.15}[/tex]

[tex]x = 4[/tex]

For the dimes:

[tex]y = x + 8 = 4 + 8 = 12[/tex]

There are 4 nickels and 12 dimes.

Final answer:

To solve the problem, we use algebra to express the relationship between the number of dimes and nickels and their total value in pennies. We find that there are 4 nickels and 12 dimes in the piggy bank.

Explanation:

Calculating the Number of Dimes and Nickels

Let's denote the number of nickels as N and the number of dimes as D. According to the problem, there are 8 more dimes than nickels, which means D = N + 8. Now, we need to convert the total value of coins into pennies because there are 100 pennies in one dollar.

The value of nickels and dimes in pennies is 5N (for nickels) and 10D (for dimes), respectively. Since the total amount is $1.40 or 140 pennies, we can express this as the equation 5N + 10D = 140.

Replacing D in the equation with N + 8 we get 5N + 10(N + 8) = 140. Simplifying this, we get 5N + 10N + 80 = 140, which simplifies further to 15N + 80 = 140.

Subtracting 80 from both sides gives us 15N = 60, and dividing both sides by 15 yields N = 4. This means there are 4 nickels.

To find the number of dimes, we substitute N with 4 in the earlier expression for D (D = N + 8) giving us D = 4 + 8, which equals 12.

Therefore, there are 4 nickels and 12 dimes.

Answer:

10d cents.

Step-by-step explanation:

This is an everyday mathematics question, in which the value of the currency has to be known. It is a fact that:

1 dime = 10 cents and 1 cent = 1/10 dimes

These relationships can be used to determine the value of the dimes in terms of cents and the value of the cents in terms of dimes respectively. In the question, it is given that there are d dimes. Therefore, using the first formula, it can be inferred that:

d dimes = 10*d cents.

So, the value of d dimes in cents is 10d cents!!!

Answer:

r = ∛(3V/4π)

Step-by-step explanation:

The formula for the volume of a sphere is V = (4/3)πr³.

We want to solve this first for r³ and then for r.

Multiplying both sides of V = (4/3)πr³ by 3 yields an equation without fractions:  3V = 4πr³.

Dividing both sides of this equation by 4π isolates r³:

       3V

r³ = -------

       4π

To find r, take the cube root of both sides of

       3V

r³ = -------

       4π

obtaining r = ∛(3V/4π)

[tex]\bf \textit{volume of a sphere}\\\\ V=\cfrac{4\pi r^3}{3}~~ \begin{cases} r=radius\\ \cline{1-1} V=113 \end{cases}\implies 113=\cfrac{4\pi r^3}{3}\implies 339=4\pi r^3 \\\\\\ \cfrac{339}{4\pi }=r^3\implies 26.98\approx r^3\implies \sqrt[3]{26.98}=r\implies 2.999 \approx r\implies \stackrel{\textit{rounded up}}{3=r}[/tex]

Answer:

(3,3)

(-5,19)

Step-by-step explanation:

y= x^2 - 6

y=-2x + 9

Set the two equations equal to each other y=y

x^2 - 6  =-2x + 9

Add 2x to each side

x^2 +2x- 6  =-2x+2x + 9

x^2 +2x- 6  = 9

Subtract 9 from each side

x^2 +2x- 6-9  =9- 9

x^2 +2x- 15 =0

Factor the left hand side

What 2 numbers multiply to -15 and add to 2

-3 *5 = -15

-3+5 = 2

(x-3) (x+5) =0

Using the zero product property

x-3 =0        x+5 =0

x=3             x=-5

Now we find y for each x

x=3

y=-2(3) + 9 = -6+9 =3

(3,3)

x=-5

y=-2(-5) + 9 = 10+9 =19

Answer:

The x-intercept is (6,0).

The y-intercept is (0,-21/2).

Step-by-step explanation:

So we are told this is a line.

Linear equations in the form y=mx+b tell us the slope,m, and the y-intercept,b.

So we are going to write our equation in this form to determine x- and y- intercept.

Let's begin.

First thing I'm going to is compute the slope.  The slope can be found by lining up the points vertically and subtracting them vertically then put 2nd difference over 1st difference.

Let's do that:

 (   -10  ,  -28)

- (    -6  ,   -21)

-----------------------

   -4             -7

So the slope is -7/-4 which is 7/4.

Now we know our equation to be in this form

y=(7/4)x+b

Use one of the points along with y=(7/4)x+b to find b.

Doesn't matter which one, you get to choose.

How about (-2,-14)?

-14=(7/4)(-2)+b

-14=-7/2+b

Add 7/2 on both sides:

-14+7/2=b

-21/2=b

So our equation is

[tex]y=\frac{7}{4}x-\frac{21}{2}[/tex]

So we already know the y-intercept is (0,-21/2).

We knew this because we were putting into slope-intercept form.

Now to find the x-intercept, set y=0 and solve for x:

[tex]0=\frac{7}{4}x-\frac{21}{2}[/tex]

Clear the fractions; multiply both sides by 4:

[tex]0=7x-42[/tex]

Add 42 on both sides:

[tex]42=7x[/tex]

Divide both sides by 7:

[tex]\frac{42}{7}=x[/tex]

So x=6

The x-intercept is (6,0).

Answer:

The correct answer is f(x) =1/2 x + 6

Step-by-step explanation:

We have to convert the equation of line in the form of a function to compare with the options

Given equation of line is:

[tex]y-8=\frac{1}{2}(x-4)\\ Distributing\ 1/2\\y-8=\frac{1}{2}x-(4)(\frac{1}{2})\\y-8=\frac{1}{2}x-2\\y=\frac{1}{2}x-2+8\\y=\frac{1}{2}x+6[/tex]

Therefore, the correct answer is f(x) =1/2 x + 6  ..

Area of a circle is found using the formula: Area = π * r^2

Using 3.14 for π

Area of the bull'e eye = π * 2^2 = 4π = 4 * 3.14 = 12.56 square inches.

This is 20% of the entire target.

To find the area of the entire target, divide the area of the bull's eye by the percentage:

Area = 12.56 / 0.20 = 62.8 square inches.

Round the answer as needed.

Answer:

Area of target = 62.8 inch²

Step-by-step explanation:

A bull’s-eye with a 4-inch diameter covers 20 percent of a circular target.

Diameter of bull's eye = 4 inch

[tex]\texttt{Area of bull's eye = }\frac{\pi\times 4^2}{4}=12.56inch^2[/tex]

Given that  bull’s-eye covers 20% of circular target.

[tex]\texttt{Area of bull's eye = }\frac{20}{100}\times \texttt{Area of target}\\\\\texttt{Area of target}\times 0.2=12.56\\\\\texttt{Area of target}=\frac{12.56}{0.2}=62.8inch^2[/tex]

Area of target = 62.8 inch²

Answer:

[tex]g(x)=x+6[/tex]

Step-by-step explanation:

we have

[tex]f(x)=x+8[/tex]

If f(x) is shifted 2 units to the right

then

The rule of the translation is

[tex]g(x)=f(x-2)[/tex]

so

[tex]g(x)=(x-2)+8[/tex]

[tex]g(x)=x+6[/tex]

Answer:  The correct option is

(D) [tex]g(x)=x+6.[/tex]

Step-by-step explanation:  Given that the following function is shifted 2 units to the right :

[tex]f(x)=x+8~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)[/tex]

We are to write the equation when the function (i) is shifted 2 units to the right.

We know that

if a function is shifted 2 units to the right, then its x co-ordinate is reduced by 2 units.

Therefore, the equation of the new function is given by

[tex]g(x)=f(x-2)=(x-2)+8=x+6.[/tex]

Thus, the required function is [tex]g(x)=x+6.[/tex]

Option (D) is CORRECT.

Answer:

35

Step-by-step explanation:

To calculate the mean(average) of a data set, add all of the numbers together and then divide by the amount of points you have.

Mean = (16+32+41+54+32)/5 because there are 5 numbers you are adding.

To find the mean of a set of data you must add the data together then divide the sum by the number of data in the set.

Step 1: Adding together the data

16 + 32 + 41 + 54 + 32 = 175

Step 2: Count how many number there are in the data set

There are 5 numbers in this data set

Step 3: Divide the sum of the data by the number of data in the set

175 ÷ 5 = 35

The mean of this data set is 35

(16x^2-1) can be factored over integers so, Option C is correct.

Step-by-step explanation:

Given: 256x^4y^2-y^2

Factorizing the given expression:

Taking y^2 common

=y^2(256x^4-1)

Using formula: a^2-b^2 = (a-b)(a+b)

=y^2((16x^2)^2-(1)^2)

y^2(16x^2+1)(16x^2-1)

y^2(16x^2+1)((4x)^2-(1)^2)

y^2(16x^2+1)(4x-1)(4x+1)

Since (16x^2-1) can be factored over integers so, Option C is correct.

Answer:

A. f(x)=155-6x

B. Plug in x=8 and solve.

Step-by-step explanation:

-we can develop an equation for this by first realizing that each week, the sales decrease by 6. thus, we know the amount of sales decreases by 6 every week so we know the formula is: the initial sales amount-6x (x being whatever week).

-we can find the initial amount by noting i=initial sales amount and using the Info from the first week.

149=i-6(1)

155=I

thus, the formula: f(x)=155-6x

- we can plug in 8=x to predict the sales amount on the eighth week:

155-6(8)

155-48

sales on eighth week=107
