What is 8640 minutes, in days?

Flura [38]

Surface Area (SA) of a Cylinder formula:
SA = 2*pi*r*h+2*pi*r^2
If you fill in the formula:
SA = 2*3.14*2*9+2*3.14*2^2
Simplify:
SA = 6.28*18+6.28*4
SA = 113.04 + 25.12
SA = 138.16 in
I hope I helped
If its wrong I'm super duper extra sorry!

Three basketball teams measured the height of each player on their team. The table shows the mean and the mean absolute deviatio

Dimas [21]

Answer:

(A) and (D)

Step-by-step explanation:

It is given that Three basketball teams measured the height of each player on their team.

Team Mean height (cm) MAD (cm)

Bulldogs 165 6.9

Panthers 177 7.1

Warriors 176 4.8

From the information given, The heights of the Bulldogs’ players vary more than do the Warriors’ heights and The heights of the Panthers’ players and those of the Warriors vary about the same amount.

Therefore, option A and d are the correct statements about the data given.

Use the segment addition postulate to write three equations using the diagram below

creativ13 [48]

Answer:

$PQ + QR = PR$ => equation 1

$RS + ST = RT$ => equation 2

$PR + RT = PT$ => equation 3

Step-by-step explanation:

Points P, Q, R, S, and T are collinear therefore, the following equations can be written based on the segment addition postulate:

$PQ + QR = PR$ => equation 1

$RS + ST = RT$ => equation 2

$PR + RT = PT$ => equation 3

More equations can actually be written from the diagram given using the segment addition postulate. Such as:

$PQ + QR + RS + ST = PT$

Find two numbers whose difference is 176 and whose product is a minimum.

Zanzabum

Let the two required numbers be x and y, then x - y = 176, thus y = x - 176.

Let the product of the two numbers be represented by

$P = xy x(x - 176) = x^2 - 176x$

For the product to be minimum, $\frac{dP}{dx} =0$

$\frac{dP}{dx} =2x - 176=0 \\ \\ \Rightarrow2x=176 \\ \\ \Rightarrow x=88$

Thus, y = 88 - 176 = -88

Therefore, the two numbers are 88 and -88.

i had 3 times as many rose bushes as holly bushes in my garden. Then i moved seven of my rose bushes to my grandfather’s garden,

PIT_PIT [208]

Total number of rose and holly bushes that I had initially = 20

<h3>System of linear equations</h3>

Let the initial number of rose bushes be r

Let the initial number of holly bushes be h

I had 3 times as many rose bushes as holly bushes in my garden

r = 3h......................(1)

After moving seven of my rose bushes to my grandfather’s garden, the remaining number of rose bushes = r - 7

After planting 11 new holly bushes in my garden, the new number of holly bushes = h + 11

Now my garden has half as many rose bushes as holly bushes

r - 7 = 0.5(h + 11)

r = 0.5h + 5.5 + 7

r = 0.5h + 12.5...............(2)

Compare equations (1) and (2)

3h = 0.5h + 12.5

3h - 0.5h = 12.5

2.5h = 12.5

h = 12.5/2.5

h = 5

Substitute h = 5 into equation (1)

r = 3h

r = 3(5)

r = 15

Total number of rose and holly bushes that I had initially = h + r

Total number of rose and holly bushes that I had initially = 5 + 15

Total number of rose and holly bushes that I had initially = 20
