Since the number after the decimal is higher or equal to 5 the number in front of the decimal goes up 1. The answer is 9 inches.

It would be rounded to 9 inches because anything 5 and over you go to the next next number

Olivia is going to an amusement park. The price of admission into the park is $40, and once she is inside the park, she will hav

svetoff [14.1K]

Answer:

Cost for 13 rides: $92

Cost for r rides: I am guessing it would be 40+4r

Step-by-step explanation:

If you automatically pay 40 dollars to get in, then that is the constant, and paying 4 dollars per ride is a coefficient, so that would be multiplied by how many rides you go on, the variable. Once you plug those into the equation above, you would get 92 dollars for the thirteen rides.

A can of tuna has a volume 18pi cm3 and a height of 2 cm. Find the area of the label that wraps around the entire can and does n

Sphinxa [80]

Answer:

The area of the label is $12\pi\ cm^{2}$

Step-by-step explanation:

step 1

Find the radius

we know that

The volume of the cylinder (can of tuna) is equal to

$V=\pi r^{2} h$

In this problem we have

$V=18\pi\ cm^{3}$

$h=2\ cm$

substitute and solve for r

$18\pi=\pi r^{2} (2)$

Simplify

$18=r^{2}(2)$

$r^{2}=9$

$r=3\ cm$

step 2

<em>Find the lateral area of the can</em>

The lateral area of the cylinder (can of tuna) is equal to

$LA=2\pi rh$

we have

$r=3\ cm$

$h=2\ cm$

$LA=2\pi (3)(2)=12\pi\ cm^{2}$

Which graph represents x

Maurinko [17]

The answer is the second graph.

$\frac{x}{3} \leq 2$
You need to isolate x, in order to do this you need to multiply both sides by 3, or 3/1
2*3 = 6
x/3 * 3 = x
Your equation should now be
$x \leq 6$

So the circle should be filled in and pointing towards the left starting from 6

Sand falls onto a conical pile at the rate of 10 cubic feet per minute. The radius of the pile is always equal to one half it al

Andreas93 [3]

Answer:

Either one of these.

Step-by-step explanation:

volumepile=1/3 (PI r^2)h

but r=h/2, so

volume=1/12 PI h^3

dv/dt=10 ft^3/min

but dv/dt=1/12 PI 3h^2 dh/dt

solve for dh/dt

This assumes you mean by "altitude" the height. If you mean altitude as slant height, you have to adjust the fromula

_______________________________________________

given: r = h/2

V = (1/3)π r^2 h

= (1/3)π (h/2)^2 (h)

= (1/12) π h^3

dV/dt = (1/4)π h^2 dh/dt

for the given data ...

10 = (1/4)π(25)dh/dt

dh/dt = 10(4)/((25π) = 1.6/π feet/min

What is the median of the following set of numbers? 15, 12, 18, 17, 13, 12, 12, 14, 15, 19 A) 15 B) 12 C)14 D)14.5

xenn [34]

Answer:

14.5

Step-by-step explanation:

you put the numbers in order, then you look at what two numbers are in the middle(if there is one number in the middle that is your median) then you take the two numbers that are in the middle and you add them up and when you get that answer you divide by two (14+15 divided by 2= 14.5)
