Answer:

The answer to your question is Volume = 14012 ft³

Step-by-step explanation:

Data

radius = 5 ft

height = 175 ft

Volume = ?

π = 22/7

Process

1.- Calculate the area of the cylinder

Volume = πr²h

-Substitution

Volume = (22/7)(5)²(175)

-Simplification

Volume = 13750 ft³

2.- Calculate the volume of a semi-sphere.

Volume = (4/3)πr³

-Substitution

Volume = (4/3)(22/7)(5)³

-Simplification

Volume = 523.8 ft³

Volume / 2 = 261.9 ft³

3.- Total volume

Volume t = 13750 + 261.9

= 14011.9 ≈ 14012 ft³

How many terms are there in a geometric series if the first terms is 2, the common ratio is 4, and the sum of the series is 2,73

arsen [322]

The sum of n terms of a geometric series is given by
$S_{n}=a_{1}\dfrac{r^{n}-1}{r-1}$

Substituting the given numbers, you have
$2730=2\dfrac{4^{n}-1}{4-1}\\\\2730\dfrac{3}{2}=4^{n}-1\\\\4096=4^{n}\\\\\dfrac{\log(4096)}{\log(4)}=n=6$

There are 6 terms in the series.

Door is 77 inches high, 35.25 inches wide and 1,75 inches thick how much paint is needed

Leviafan [203]

If you wanted to paint the entire door (even the top and bottom which people don't usually paint)

the surface area is
SA=2(LW+LH+WH)
where L=length, W=width and H=height

given
L=35.25
W=1.75
H=77

SA=2(35.25*1.75+35.25*77+1.75*77)
SA=2(61.6875+2714.25+134.75)
SA=2(2910.6875)
SA=5821.375

you need enough paint to cover 5821.375 square inches of door

Graph this function: y = 2x

77julia77 [94]

Graph is attached below.

Step-by-step explanation:

We have to graph function y = 2x,

From equation, we can see a linear relationship between the values of x and y. This equation shows that the value of y is double than the value of x.

For example,

x = 0

y = 2(0)

y = 0

So, point would be (0,0)

x = 1

y = 2(1)

y = 2

So, point would be (1,2)

x = 3

y = 2(3)

y = 6

So, point would be (3,6)

x = -1

y = 2(-1)

y = -2

So, point would be (-1,-2)

x = -3

y = 2(-3)

y = -6

So, point would be (-3,-6)

By matching these points, a linear graph can easily be drawn. I have also attached the graph pic below.

Hurry I need the answers plz and how u got it

aleksley [76]

There are 122,100 public school teachers in Ohio and Ohio has a population of 11.6 million people. Illinois has a population of 12.9 million people. If the number of public school teachers per capita in Illinois was proportional to that of Ohio, how many public school teachers would we expect Illinois to have?

This problem uses proportionality or the relationship between two values. Typically, proportions are expressed as fractions. So, we can set this up as

$\frac{Teachers}{Population}$ and we can use this to express both of our values. So, for Ohio, we have $\frac{122,100}{11,600,000}$ and for Illinois we have $\frac{x}{12,900,900}$ . Now, because they are proportional, we can set them equal to each other and we get $\frac{122,100}{11,600,00} = \frac{x}{12,900,000}$ . Now we can cross multiply to get $11,600,000x=1446090000000$ . To get the $x$ alone on one side, we divide by $11,600,000$ and we get 124,662.931034, which is about equal to 124,663.

Therefore, we expect Illinois to have 124,663 public school teachers
