In 2014 the tenants at Jefferson school’s Fall festival Was 650. In 2015 the attendance was 575. What was the percent change in

navik [9.2K]

The percent change in attendance from 2014 to 2015 is 11.54 %

Solution:

Given that,

In 2014 the tenants at Jefferson school’s Fall festival Was 650

In 2015 the attendance was 575

To find: percent change in attendance from 2014 to 2015

Percentage change equals the change in value divided by the absolute value of the original value, multiplied by 100.

$\text {Percent change }=\frac{\text { change in attendance from } 2014 \text { to } 2015}{\text { atendance in } 2014} \times 100$

Change in attendance from 2014 to 2015 = attendance from 2014 - attendance from 2015

Change in attendance from 2014 to 2015 = 650 - 575 = 75

Therefore percentage change is given as:

$\text {Percent change }=\frac{75}{650} \times 100=\frac{7500}{650}=11.54$

Thus the percent change in attendance from 2014 to 2015 is 11.54 %

A gym memebership costs a flat fee of $68 and an additional $19.99 per month.Since she became a member Ellen has paid the gym $2

fomenos

Answer:

She has been a member of the gym for seven months

Step-by-step explanation:

In this question, we are asked to calculate the number of months a customer has been a member of a gym, given the pricing template of the gym.

Now, as we can see from the question, there are two kinds of fees to be paid. The flat fee and the subscript class.

First, let’s represent the number of months she has been a member of the gym by m. This means the total amount of money she has paid for m months would be m * 19.99m

Now, recall, we have a flat fee of $68, adding this to the total monthly payment for m months bring the wages to 19.99m + 68

This is said to equal $207.93

This means;

19.99m + 68 = 207.93

19.99m = 207.93 -68

19.99m = 139.93

m = 139.93/19.99 = 7

Sketch the region bounded by the curves, and visually estimate the location of the centroid. y = 2x, y = 0, x = 1 WebAssign Plot

ASHA 777 [7]

Answer:

the graph is in the attachment.

the coordinates of the centroid : (2/3,2/3)

Step-by-step explanation:

y=0 represents x-axis ( you can easily mark it on the graph)

now draw x=1 line.( It is a line parallel to y axis and passing through the point (1,0) )

y=2x is a line which passes through origin and has a slope "2"

by using these sketch the region.

I have uploaded the region bounded in the attachment. You may refer it. The region shaded with grey is the required region.

to find centroid:

it can be easily identified that the formed region is a triangle

the coordinates of three vertices of the triangle are

(1,2) , (0,0) , (1,0)

( See the graph. the three intersection points of the lines are the three vertices of the triangle)

for general FORMULA, let the coordinates of three vertices of a triangle PQR be P(a,b) , Q(c,d) , R(e,f)

then the coordinates of the centroid( let say , G) of the triangle is given by

G = $(\frac{a+c+e}{3} , \frac{b+d+f}{3} )$

therefore , the exact coordinates of the centroid =

$(\frac{1+0+1}{3}, \frac{2+0+0}{3} ) = (\frac{2}{3}, \frac{2}{3} )$

this point is marked as G in the graph uploaded.

Which of the following rotations will produce a 12-sided polyhedron? ANSWERS: Rotating a 12-gon about a vertical axis running al

Komok [63]

Answer:

No rotation will produce a polyhedron. The solids of rotation are non-polyhedral.

Step-by-step explanation:

Solids of rotation will always have a curved face, so they’re always non-polyhedral.
