Alana earnerd money doing chores. Her grandmother agreed to add $4.00 to the amount Alana earned and then give her half of that sum. Alana's grandmother gave her gave her $4.25. Write and solve an equation to find the amount of Alana's donation

Answers

Answer:

Hence amount of Alana's donation is $4.5.

Step-by-step explanation:

Amount of Alana's donation = x

Her grandmother agreed to add $4.00 to the amount Alana earned.

So new amount of money = (x+4)

She gives only half of the sum which is (x+4)/2.

She gave her $4.25 so both values must be equal.

[tex]\frac{\left(x+4\right)}{2}=4.25[/tex]

[tex]x+4=4.25*2[/tex]

[tex]x+4=8.5[/tex]

[tex]x=8.5-4[/tex]

[tex]x=4.5[/tex]

Hence amount of Alana's donation is $4.5.

Alana earned $4.50 from doing chores before her grandmother added an additional $4.00 and then gave her half of the total, which was $4.25.

The question relates to finding out how much money Alana earned by doing chores before her grandmother added $4.00 and then gave her half. In this scenario, we let x represent the amount of money that Alana earned from doing chores. According to the information provided, Alana's grandmother agreed to add $4.00 to Alana's earnings and then give her half of the total sum. This can be expressed as:

(x + 4.00) / 2 = 4.25

To solve for x, we first multiply both sides of the equation by 2 to get rid of the denominator:

x + 4.00 = 4.25 * 2

x + 4.00 = 8.50

Next, we subtract $4.00 from both sides of the equation to solve for x:

x = 8.50 - 4.00

x = 4.50

Therefore, the amount of money Alana earned from doing chores is $4.50.

Given the regular decagon (10-sided polygon), which statements are true?


Choose all that apply
A. The polygon has 90° rotational symmetry
B. The polygon has 36° rotational symmetry
C. The polygon has 144° rotational symmetry
D. The polygon has point symmetry

Answers

D. The polygon has point symmetry
Final answer:

The regular decagon has 36° rotational symmetry and point symmetry because it can map onto itself by rotating 36° and when flipped 180° around its center.

Explanation:

The subject of the question is a regular decagon, which is a 10-sided polygon.

To find out which statements are true regarding its symmetry, consider that rotational symmetry of a polygon is determined by the angle of rotation that maps the polygon back onto itself without altering its general outline.

For a regular decagon, the angle of rotation that achieves this is 360 degrees divided by the number of sides, which is 10 in this case.

Therefore, the correct angle of rotational symmetry is 360/10 = 36 degrees.

Thus, the correct answer from the provided options is:

B. The polygon has 36° rotational symmetryD. The polygon has point symmetry

which equation and ordered pair represent the correct vertex form and vertex for j(x) = x^2 - 12 x +7?

Answers

Answer:

see explanation

Step-by-step explanation:

the equation of a parabola in vertex form is

y = a(x - h)² + k

where (h, k) are the coordinates of the vertex and a is a multiplier

Given the equation in standard form : ax² + bx + c : a ≠ 0

then the x-coordinate of the vertex is

[tex]x_{vertex}[/tex] = - [tex]\frac{b}{2a}[/tex]

j(x) = x² - 12x + 7 is in standard form

with a = 1, b = - 12 and c = 7, hence

[tex]x_{vertex}[/tex] = - [tex]\frac{-12}{2}[/tex] = 6

substitute x = 6 into j(x) for y- coordinate

y = 6² - 12(6) + 7 = 36 - 72 + 7 = - 29

vertex = (6, - 29 ) and

j(x) = (x - 6)² - 29 ← equation in vertex form

The account after 20 years is $73798.8.

Step-by-step explanation:

Given : James and Terry open a savings account that has a 2.75% annual interest rate, compounded monthly. They despoit $400. Into the account each month.

To find : How much will be in the account after 20 years ?

Solution :

Using monthly payment formula,

[tex]M=\frac{\text{Amount}}{\text{Discount factor}}[/tex]

Discount factor is [tex]D=\frac{1-(1+i)^{-n}}{i}[/tex]

Substitute in the formula,

[tex]\text{Amount}=M\times \frac{1-(1+i)^{-n}}{i}[/tex]

Where, M=$400 amount deposited monthly

r= 2.75%=0.0275 is the interest rate

[tex]i=\frac{0.0275}{12} =0.00229[/tex]

t=20 years is the time

[tex]n=12\times 20=240[/tex]

Substitute the value,

[tex]\text{Amount}=400\times \frac{1-(1+0.00229)^{-240}}{0.00229}[/tex]

[tex]\text{Amount}=400\times \frac{1-0.5775}{0.00229}[/tex]

[tex]\text{Amount}=400\times 184.497[/tex]

[tex]\text{Amount}=73798.8[/tex]

Therefore, the account after 20 years is $73798.8.

A candy mixture is made from 6 pounds of sugar sticks of $10 per pound and 14 pounds of jelly beans of $8 per pound. Find the price of the candy mixture per pound.

Answers

6 × 10 = 60$ per 6 pounds
14 × 8 = 112$ per 14 pounds

you'll get 20 pounds of the candy mixture and will cost 172

172/20
8.6$ per pound

Final answer:

The price of the candy mixture per pound is $8.60.

Explanation:

To find the price of the candy mixture per pound, we need to calculate the total cost of the sugar sticks and jelly beans, and then divide it by the total weight of the candy mixture.

Let's start by calculating the total cost of the sugar sticks. The cost per pound of sugar sticks is $10, and we have 6 pounds of sugar sticks, so the total cost of the sugar sticks is 6 x $10 = $60.

Next, let's calculate the total cost of the jelly beans. The cost per pound of jelly beans is $8, and we have 14 pounds of jelly beans, so the total cost of the jelly beans is 14 x $8 = $112.

Now, let's calculate the total weight of the candy mixture. We have 6 pounds of sugar sticks and 14 pounds of jelly beans, so the total weight of the candy mixture is 6 + 14 = 20 pounds.

Finally, let's calculate the price of the candy mixture per pound. We divide the total cost of the candy mixture by the total weight of the candy mixture: ($60 + $112) / 20 = $172 / 20 = $8.60.

Therefore, the price of the candy mixture per pound is $8.60.

How do you solve this? r^2+32=12r

Answers

Answer:

r = {-8, -4}

Step-by-step explanation:

Simplifying

r2 = -32 + -12r

Solving

r2 = -32 + -12r

Solving for variable 'r'.

Reorder the terms:

32 + 12r + r2 = -32 + -12r + 32 + 12r

Reorder the terms:

32 + 12r + r2 = -32 + 32 + -12r + 12r

Combine like terms: -32 + 32 = 0

32 + 12r + r2 = 0 + -12r + 12r

32 + 12r + r2 = -12r + 12r

Combine like terms: -12r + 12r = 0

32 + 12r + r2 = 0

Jasmine borrowed $15,000 for 8 years and she paid $6,600 in interest. What was the interest rate for Jasmine's loan?

A) .055%

B) 6%

C) 3.25%

D) 5.5%

Answers

Answer:

D) 5.5%

Step-by-step explanation:

To find the interest rate, use the equation:  I = prt


I = Interest = $6,600


p = principal = $15,000


r = rate = unknown


t = time = 8 years



Now plug the numbers into the equation.


6,600 = 15,000 * r * 8


6,600 = 120,000 * r



Now isolate the variable by dividing both sides of the equation by 120,000.


0.055 = r



Now change the rate to a percent by moving the decimal point 2 digits to the right.


5.5% = r   OR   r = 5.5%

Answers

Answer:

finding the number of equal-sized parts into which a number can be split

Step-by-step explanation:

Let us split the number 80 into 10 equal parts.

80 = 8 + 8 + 8 + 8 + 8 + 8 + 8 + 8 + 8 + 8

= 8 + 8 + 8 +...to 10 times

= 8(10)

or [tex]\frac{80}{10} =8[/tex]

So, if N is any number and p is one of its equal part, then the number of parts into which N is split by p is [tex]\frac{N}{p}[/tex].

Hence, finding the number of equal-sized parts is best modeled with a division expression.

Answer:

Finding the number of equal-sized parts into which a number can be split

Step-by-step explanation:

The correct answer is - finding the number of equal-sized parts into which a number can be split.

Division is defined as the action of splitting something in equal parts.

So, here the first option states this definition.

Taking an example of: Lets divide 100 in 5 equal parts. So, this becomes

[tex]\frac{100}{5}=20[/tex]

This can be also written like : [tex]20+20+20+20+20=100[/tex]

So, division is where you split something equally.

To find sum of geometric series we use formula

[tex]S_n = \frac{a(1-r^n)}{1-r}[/tex]

In the question , given i=1  so a= 11* -1/5 = -11/5

Here a= 11

r= -1/5, n=10

Plug in the values in the formula

[tex]S_10 = \frac{-11}{5}*\frac{(1-(\frac{-1}{5})^{10}}{1-(\frac{-1}{5})}[/tex]

S_10 = -1.83



Final answer:

The correct option is c.

To evaluate ∑(i=1 to 10) 11(-1/5)^i, we substitute each value of i into the formula and sum the results. Rounding the answer to the nearest hundredth gives -0.01.

Explanation:

To evaluate the given expression, we need to substitute each value of i from 1 to 10 into the formula 11(-1/5)^i and then sum up the results:

i = 1: 11(-1/5)^1 = -11/5i = 2: 11(-1/5)^2 = 11/25i = 3: 11(-1/5)^3 = -11/125i = 4: 11(-1/5)^4 = 11/625i = 5: 11(-1/5)^5 = -11/3125i = 6: 11(-1/5)^6 = 11/15625i = 7: 11(-1/5)^7 = -11/78125i = 8: 11(-1/5)^8 = 11/390625i = 9: 11(-1/5)^9 = -11/1953125i = 10: 11(-1/5)^10 = 11/9765625

Summing up all these values, we get:
-11/5 + 11/25 - 11/125 + 11/625 - 11/3125 + 11/15625 - 11/78125 + 11/390625 - 11/1953125 + 11/9765625 ≈ -0.00001

Women athletes at the a certain university have a long-term graduation rate of 67%. Over the past several years, a random sample of 42 women athletes at the school showed that 23 eventually graduated. Does this indicate that the population proportion of women athletes who graduate from the university is now less than 67%? Use a 1% level of significance.

Answers

Answer:

The null and alternative hypotheses are:

[tex]H_{0}: p=0.67[/tex]

[tex]H_{a} : p <0.67[/tex]

Under the null hypothesis, the test statistic is:

[tex]z=\frac{\hat{p}-p}{\sqrt{\frac{p(1-p)}{n} } }[/tex]

Where:

[tex]\hat{p}= \frac{23}{42} = 0.5476[/tex]

[tex]\therefore z = \frac{ 0.5476 -0.67}{\sqrt{\frac{0.67(1-0.67)}{42} }}[/tex]

         [tex]=\frac{-0.1224}{0.072555398}[/tex]

         [tex]=-1.69[/tex]

Now, we have to find the left tailed z critical value at 0.01 significance level using the standard normal table. The z critical value at 0.01 significance level is:

[tex]z_{critical} = -2.33[/tex]

Conclusion: Since the test statistic does not fall in the critical region, therefore, we fail to reject the null hypothesis, and conclude that there is not sufficient evidence to say that the population proportion of women athletes who graduate from the university is now less than 67%.


Answer: No

Step-by-step explanation:

By considering the given information , the null and the alternative hypotheses will be :-

[tex]H_0: p=0.67\\\\H_a: p<0.67[/tex]

Since the alternative hypotheses is left-tailed , so the test applied here is left-tailed.

Sample size : n= 42

The sample proportion of graduated : [tex]\hat{p}=\dfrac{23}{42}\approx0.55[/tex]

The test statistic for population proportion :-

[tex]z=\dfrac{\hat{p}-p}{\sqrt{\dfrac{p(1-p)}{n}}}[/tex]

i.e. [tex]z=\dfrac{0.55-0.67}{\sqrt{\dfrac{0.67(1-0.67)}{42}}}\approx-1.65[/tex]

The p-value : [tex]P(z<-1.645)=0.0494715[/tex]

Since the p-value is greater than the significance level, then we do not reject the null hypothesis.

Hence, it does not give enough evidence to indicate that the population proportion of women athletes who graduate from the university is now less than 67%.

The number of points the stock changed in a week will be equal to -1 2/3.  Hence, option D is correct.

What are arithmetic Operations?

The four fundamental operations of arithmetic are addition, subtraction, multiplication, and division of two or even more items.

Included in them is the study of integers, especially the order of operations, which is important for all other areas of mathematics, notably algebra, data management, and geometry.

As per the given information in the question,

Value of a stock increased 14 2/3 twice in one week.

Then, its value will be.

= 2 × 14 2/3

= 2 × 44/3

= 88/3

Then, the other 3 days it decreased by 10, 8 1/3, and 12 2/3 points.

So, the total decrease will be,

10 + 25/3 + 38/3

= (30 + 25 + 38)/3

= 93/3

So, the value of stock change will be,

88/3 - 93/3

= - 5/3 or,

In mixed fraction form, it can be written as -1 2/3.
