Answer:
3 inches=60 miles
Step-by-step explanation:
Multiply 0.5 times 6 because 1/2 an inch equals 10 miles. 0.5 x 6 = 3. 6 x 10 = 60. The actual distance between Aurora Springs and Glendale is 60 miles or 3 inches

Dennis wants to save $189 for a trip to an amusement park. He sets aside $14 of his allowance at the end of each week. How many weeks will it take him to save enough money for the whole trip?
Answer:
x = 13.5 weeks
Step-by-step explanation:
Since he wants to save $189 in total, that will be on one side of the equation by itself. You have to set this up in a y = mx + b equation. The y will be the 189. Since the word "each" goes with the number 14, that will be your m value. There is no value for b.
189 = 14x is your equation. The only step after setting up the equation is to divide 189 by 14. This gives you 13.5. Dennis will have to save up for 13.5 weeks.
The boundary of a lamina consists of the semicircles y = 1 − x2 and y = 64 − x2 together with the portions of the x-axis that join them. Find the center of mass of the lamina if the density at any point is proportional to its distance from the origin.
Answer:
The center mass of the lamina = [tex]{\begin {pmatrix} 0, \dfrac{1755}{146 \pi } \end {pmatrix}[/tex]
Step-by-step explanation:
Let take a look at the boundary of the lamina that comprises of the semicircles [tex]y = \sqrt{1-x^2}[/tex] and [tex]y = \sqrt{64-x^2}[/tex]
We are also informed that the density at any point is proportional to its distance from the origin.
Thus, the main task required is to find the center mass of the lamina.
In as much as the density is proportional to the distance from the origin;
Then;
[tex]\rho (x,y) = k \sqrt{x^2 + y^2} = kr[/tex]
Thus; the mass of the lamina is determined as:
[tex]m = \iint \limits _ D \rho (x,y) \ dA= \int ^{\pi}_{0}\int ^{8}_{1} kr.r dr d \theta[/tex]
[tex]m = \int ^{\pi}_{0}\int ^{8}_{1} kr^2 dr d \theta[/tex]
[tex]m = k \int ^{\pi}_{0} \begin {bmatrix} \int \limits ^8_1 r^2 dr \end {bmatrix} d \theta[/tex]
[tex]m = k \int ^{\pi}_{0} \begin {bmatrix} \int \limits\dfrac{r^3}{3} \end {bmatrix} ^8_1d \theta[/tex]
[tex]m = k \int ^{\pi}_{0} \begin {bmatrix} \dfrac{512}{3}- \dfrac{1}{3} \end {bmatrix} d \theta[/tex]
[tex]m = \dfrac{511 \ k}{3} \int \limits ^{\pi}_{0} \ d \theta[/tex]
[tex]m = \dfrac{511 \ k}{3} \bigg (\theta \bigg ) ^{\pi}_{0}[/tex]
[tex]m = \dfrac{511 \ k \pi}{3}[/tex]
Now, about the y-axis, the moment of the entire lamina can be computed as:
[tex]M_y = \iint \limits _D x\rho (x,y) \ dA = \int \limits^{\pi}_{0} \int \limits ^{8}_{1} r cos \theta kr .r \ dr \ d \theta[/tex]
[tex]M_y = k \int \limits ^{\pi}_{0} \int ^{8}_{1} \ cos \theta . r^3 \ dr \ d \theta[/tex]
[tex]M_y = k \begin {bmatrix} \int \limits ^{\pi}_{0} cos \theta d \theta \end {bmatrix} \begin {bmatrix} \int \limits ^8_1 r^3 dr \end {bmatrix}[/tex]
[tex]M_y = k (sin \ \theta )^{\pi}_{0} \begin {bmatrix} \dfrac{r^4}{4} \end {bmatrix}^8_1[/tex]
[tex]M_y = k(sin \pi - sin 0 ) \bigg ( \dfrac{8^4}{4}- \dfrac{1^4}{4} \bigg)[/tex]
[tex]M_y = 0[/tex]
Similarly; about the x-axis, the moment of the entire lamina can be computed as:
[tex]M_x = \iint \limits _D y \rho (x,y) \ dA = \int \limits^{\pi}_{0} \int \limits ^{8}_{1} r sin \theta kr .r \ dr \ d \theta[/tex]
[tex]M_x = k \int \limits ^{\pi}_{0} \int ^{8}_{1} \ sin \theta . r^3 \ dr \ d \theta[/tex]
[tex]M_x = k \begin {bmatrix} \int \limits ^{\pi}_{0} sin \theta d \theta \end {bmatrix} \begin {bmatrix} \int \limits ^8_1 r^3 dr \end {bmatrix}[/tex]
[tex]M_x= k (- cos \ \theta )^{\pi}_{0} \begin {bmatrix} \dfrac{r^4}{4} \end {bmatrix}^8_1[/tex]
[tex]M_x = k(-cos \pi +cos 0 ) \bigg ( \dfrac{8^4}{4}- \dfrac{1^4}{4} \bigg)[/tex]
[tex]M_x = \dfrac{4095}{2}k[/tex]
Hence, The center mass of the lamina is:
[tex]( \overline x, \overline y) = \bigg ( \dfrac{M_y}{m}, \dfrac{M_x}{m} \bigg )[/tex]
[tex]( \overline x, \overline y) = \begin {pmatrix} \dfrac{0}{\dfrac{511 \ k \pi}{3}}, \dfrac{\dfrac{4095 \ k}{2}}{\dfrac{511 \ k \pi}{3}} \end {pmatrix}[/tex]
[tex]( \overline x, \overline y) = \begin {pmatrix} 0, \dfrac{1755}{146 \pi } \end {pmatrix}[/tex]

Marc earns $45,000 per year. If he does not work for 2 months in a year, how much money would he earn?
Answer:
$37500
Step-by-step explanation:
45000 divided by 12 = 3750
3750 is how much he earns each month.
3750x2=7500
7500 is how much he earns in 2 months
45000-7500=37500
Answer:
37,500
Step-by-step explanation:
if he makes 45,000 a year, we need to find out how much he makes per month.
divide 45,00 by 12= 3750 per month
3750 times 2 months= 7500
45,000-7,500= 37,500

the length of a rectangular sign is 4 times it's width. if the sign's perimeter is 30 inches, what is the area?
Answer:
36
Step-by-step explanation:
Width = x
Length = 4x
Perimeter = Width + Width + Length + Length (Because there are four sides; two sides are the widgth and two sides are the length)
30 (because 30 is given as the perimeter) = x + x + 4x + 4x
30 = 10x
x = 3
Width = 3
Length = 4(3) = 12
Area = Width * Length
Area = 3 * 12 = 36
The area of the rectangular sign is equal to 36 square inches, if its perimeter is 30 inches.
Let the length of the rectangular sign be L.Let the width of the rectangular sign be W.Given the following data:
Perimeter of rectangular sign = 30 inches.Translating the word problem into an algebraic equation, we have;
[tex]L = 4W[/tex]
Mathematically, the perimeter of a rectangle is given by the formula;
[tex]P = 2(L+W)\\\\30 = 2(4W + W)\\\\30 = 2(5W)\\\\30 = 10W\\\\W = \frac{30}{10}[/tex]
Width, W = 3 inches
For its length:
[tex]L = 4W\\\\L = 4(3)[/tex]
Length, L = 12 inches.
Now, we can determine the area of the rectangular sign by using the formula:
[tex]Area = LW\\\\Area = 12(3)[/tex]
Area = 36 square inches.
Therefore, the area of the rectangular sign is equal to 36 square inches.

Graph the data below and then answer the questions that follow. year 1=$20,000, year 2=$21,750, year 3=$23,500, year 4=$25,250, year 5=$27,000. is this an arithmetic sequence? How do you know?
Answer:
Since the difference between the value for each year is constant, this is an arithmetic sequence.
Step-by-step explanation:
Year 2 - Year 1 = 21,750 - 20,000 = 1,750
Year 3 - Year 2 = 23,500 - 21,750 = 1,750
Year 4 - Year 3 = Year 5 - Year 4 = 1,750

4) Jamar is driving cross-country from California to Florida over seven day. Each day from
Monday through Friday, he drives 451.15 miles. On Saturday and Sunday, he drives half this
distance each day. How many miles will Jamar drive in the entire week? Tell me how you got the answer for Brainlyest
Answer:
2,706.9
Step-by-step explanation:
451.15 × 5 = 2,255.75
451.15 ÷ 2 = 225.575
2,255.75 + 225.575 = 2,481.325
2,481.325 + 225.575 = 2,706.9
total= 2,706.9

Given that Jocelyn saved $60 in 8 weeks, predict the number of weeks it will take Jocelyn to save $90. Include in your explanation any assumptions that must be made in order to make the prediction. Enter your explanation in the space provided.
number of weeks: w is the x value, and the number of money saved: m is the y value. First, we need to find out how much she makes in 1 w and because k = y/x, we need to divide 60 by 8, which gives u 7.5, so she saves $7.50 every week Finally, we figure out the number of weeks it takes her to save $90, and to do that, we use the formula x = y/k. Using that formula, we get the expression $90/$7.50 or $90/$7.5. 90/7.50 = 12, so x = 12. It will take her 12 weeks to save $90. In order to check our answer, we can say that we didn't know the number of m she saved, but we do know how many weeks. To find a solution, we use the formula y = kx (the blank between kx means that we are multiplying). Using that formula, we get the equation 12 X 7.50. When we solve this equation, we get 90, and since it is the same answer as the real problem, that means the answer for the real problem is correct. (BTW sorry this is so long)
