A cylinder has a base diameter of 18ft and a height of 16ft. What is its volume in cubic ft, to the nearest tenths place?​

Answers

Answer 1
Answer:

Answer:4073 cubic feet

Step-by-step explanation:

VOLUME OF A CYLINDER

V=Πr²h

radius = diameter/2 =18/2 =9ft

V= 22/7 × 9² × 16

=28512/7

=4073.14

V= 4073 cubic feet to the nearest tenth

Write the slope intercept form of the equation of the line through the given points and slope 1,1 and slope of -3/5

Answers

Slope is already given in the question so we only need to solve for the y-intercept.

Slope intercept form: y = mx + b

m = slope

b = y-intercept

-3/5 = -0.6

1 = -0.6(1) + b

1 = -0.6 + b

1 + 0.6 = -0.6 + b + 0.6

1.6 = b

Now, write in slope-intercept form.

y = -3/5x - 1.6

Simplify each expression using the properties of numbers

Answers

Firstly you should add the like terms i.e. 5x + x. So The answer will be 6x + 2. If it requires you to factorise then take out the highest common factor i.e. 2. So factorised the answer will be 2(3x + 1). 

at a wonderful water park, the water trough ride $2.75 per ride. if you have $15, then how many times could you ride

Answers

Answer:

5 times

Step-by-step explanation:

Since it is 2.75 dollars per ride if you multiply 2.75 times 5 you get $13.75 and you cant add anymore.
DO 15\2.75 (Divide)

You should get 5.4545454545

So you will have to round

So you can ride it about 5 times
