This composite figure is made of three identical cylinders that are connected together

Radius:3 Height:8

Answers

Answer 1
The surface are of a cylinder is

SA = 2πr2 + 2πrh

where:
r = radius
h = height

This formula comes from adding the areas of the surfaces of the cylinder. It has two flat circular faces and a rounded face.

If we cut the cylinder from the circular face symmetrically, the surface area for one piece will be

SA = 2[(πr2)/2] + (2πr/2)h + 2rh

We will have 2-half flat circular faces, a flat rectangular surface, and half of the rounded surface.

Simplify the SA formula.

SA = πr2 + πrh + 2rh
SA = r(πr + πh + 2h)

Substitute the values into this formula.

SA = 3(3π + 8π + (2*8))
SA = 3(11π + 16)
SA = 33π + 48
SA = 151.67 cm2

Since we have 2 pieces, multiply this result by 2.

2(151.67 cm2) = 303.34 cm2.

The total area is 303.34 cm2.

During the period 1800-1900, 6 out of the 23 u.s. Vice Presidents later became U.S. presidents during the period 1901-200 7 out of 21 presidents later became presidents. During which period did a greater fraction of Vice Presidents become presidents?

Answer:

The relative ease with which the United States dispatched the Spanish squadron in Manila Bay was only the beginning of what would become a nearly 50-year American presence in the Philippines. It was one thing to capture the islands, but another thing entirely to set up a working administration. The Philippines encompasses about 7,100 islands and sits nearly 8,600 miles away from Washington, DC ...

Step-by-step explanation:

You can solve this in more than 1 way. The easiest way to solve though is by diving.
Step one: create a fraction
6/23 1800-1900
7/21 1901-2000

Step Two:
Divide the fractions. (Divide the numerator by the denominator, top by bottom)
6/23 ≈ .26
7/21 ≈ .33

From here you can see that 7/21 is greater because it has a greater number. I hope this helps!

Answer:

12 shirts

Step-by-step explanation:

First, let x = # of shirts and y = total cost in $. Then create an equation with x and y representing each company. The first company is y = 9.65x + 43 and the second company is y = 8.40x + 58. Since we need to find the # of shirts that would result in the equal total cost, we need to find x when y is equal to the other. Thus here is the setup: 9.65x + 43 = 8.40x + 58, and we would get 1.25x = 15, so x = 12.

First you set up your equations
Company 1–> 9.65x+43
Company 2–> 8.40x+58

Next you set them equal to each other
9.65x+43=8.40x+58
9.65x-8.40x=58-43
1.25x=15/1.25
x=12
When you plug 12 into both equations you’ll get that they both equal 158.8

What is the ending balance?
Enter your answer in the box. $.

Answers

Answer:

The balance in the bank after 5 years of 6.5% interest is $5,300.

Step-by-step explanation:

*Presuming that this is not a compounding interest the interest would just multiply by the even balance.*

So every 5 years the balance earns 0.065 of 4,000 dollars.

This would make our equation:

4000 + (4000  x .065 x 5 )

= 4000 + (1300)

= 5300

The balance in the bank after 5 years of 6.5% interest is $5,300.

A triangle has an area of 15. One of its sides has length 10. What is the length of the altitude to that side?

Answers

Answer:

Altitude = 3

Step-by-step explanation:

Given the area of a triangle as 15, with a length of 10:

We can use the following formula for finding the area of a triangle:

Area (A) = ½bh  

Where:

Base (b) = 10

Height (h) or altitude = unknown

Substitute the given values into the formula:

Area (A) = ½bh  

15 = ½(10)h  

15 = 5h

Divide both sides by 5 to solve for h:

[tex]\displaystyle\mathsf{\frac{15}{5}\:=\:\frac{5h}{5} }[/tex]

h = 3

Therefore, the length of the altitude or height of the given triangle is 3.

When thinking of things that “fall in the fall,” perhaps the first things that come to your mind are leaves? For many people around the country, the leaves are falling from their trees, and hours of raking are necessary. Joe decided that he would try to make some extra money by raking the leaves in his neighbors’ yards. Joe figured he would need approximately seven bags per yard in which to collect the leaves. The bags are sold 10 to a box, and Joe is planning on raking 14 yards. How many boxes of bags
must he buy?

Another thing that seems to “fall in the fall” is the temperature. Heather noticed that the high temperature on October 21st was 66 degrees, the high temperature on October 26th was 63 degrees and the high temperature on October 31st was 60 degrees. It appears that the high temperatures on every fifth day are forming an arithmetic sequence. If this sequence were to continue, on what date would the high temperature be 33 degrees?

A third thing that tends to “fall in the fall” is people’s amount of physical activity. It is believed that people generally gain weight in the colder months in large part due to this lack of physical activity. Lou decided to be proactive about this and promised himself he would exercise at least four days of every calendar week (or every Sunday through Saturday time period). If Lou never wants to skip exercising on consecutive days within a calendar week, and he exercises exactly four days out of the seven, how many
different workout schedules are possible for a calendar week?

Answers

Answer:

For one you would need 10 boxes of bags you would approximately need 98 bags.

for two The temp. would reach 33 degrees by December 15th.

for three.... I have no clue :/ If I figure it out I will get back to you

Step-by-step explanation:

1. 7 bags per yard, you have 14 yards so 14x7=98 which you should round to 100 bags which would be 10 boxes if each box has 10 bags  

2. all I did was follow the pattern (using a 2021 calendar so I wouldn't mess up the days)  went through months following the pattern every five days the temp. goes down by 3 degrees.

Joe would need to buy 10 boxes out of which 2 bags will be unused. The date on which temperature will be 33 degrees is 30th December. The schedule should be Monday, Wednesday, Friday, and Sunday.

1.

Given information:

Joe figured he would need approximately 7 bags per yard in which to collect the leaves.

The bags are sold 10 to a box, and Joe is planning on raking 14 yards.

The number of bags required to collect the leaves from 14 yards will be,

[tex]14\times7=98\rm\; bags[/tex]

So, the number of boxes required will be,

[tex]b=\dfrac{98}{10}\\b=9.8[/tex]

Since the number of boxes can't be a fraction. Joe would need to buy 10 boxes out of which 2 bags will be unused.

2.

Given information:

The high temperature on October 21st was 66 degrees, the high temperature on October 26th was 63 degrees and the high temperature on October 31st was 60 degrees.

The temperature on every fifth day forms an AP. SO, the AP will be 66, 63, 60, .....

It is required to find the date on which the temperature will be 33 degrees.

The place of term 33 in the AP will be,

[tex]a_n=a+(n-1)d\\33=66+(n-1)(-3)\\n-1=11\\n=12[/tex]

33 is placed in 12th position. So, after [tex]12\times5=60[/tex] days, the temperature will be 33 degrees.

Therefore, the date on which temperature will be 33 degrees is 30th December.

3.

Lou decided to be proactive about this and promised himself he would exercise at least four days of every calendar week.

Lou never wants to skip exercising on consecutive days within a calendar week.

He will work on consecutive days and four days a week. So, there is only one possibility to match the condition.

The schedule should be Monday, Wednesday, Friday, and Sunday.
