Container at the petting zoo holds 8138.88 cm³ of green visitors can feel peoples homes with rain from the container the cones h
slamgirl [31]

Answer:

We can fill the cone 54 times with the grain.

Step-by-step explanation:

Amount of grain = 8138.88 cm³

Dimensions of cone:

Radius = 4 cm

Height = 9 cm

Volume of 1 cone =

V = \displaystyle\frac{1}{3}\pi r^2 h\\\\V = \frac{1}{3}(3.14)(4)^2(9)\\\\V = 150.72\text{ cubic cm}

Let n be the number of times the cone that can be filled.

Thus, we can write:

\text{Amount of grain} = n \times \text{Volume of cone}\\8138.88 = n \times 150.72\\\\n = \dfrac{8138.88}{150.72}\\\\n = 54

Thus, we can fill the cone 54 times with the grain.

if p represents doubling the dimensions of a rectangle and q represents the area increasing by a factor of 4 , what could be tru
dusya [7]

Answer:

Step-by-step explanation:

I don't know the full question, or whether this had answer choices, but let's put this into a mental picture. (Found the answer choices online, should have added that, but alright.) It states that there's a rectangle and p is representing the dimensions to be doubled. You could stop there and draw a rectangle, nothing too fancy.

We know that a rectangle has 4 right angles, and 2 sides that match. A square with two longer sides. They're being doubled, so it'd be 2p. It's being increased by a factor of four. An area of a rectangle is BXH.

A. p → q represents the original conditional statement.  (True)

If you double the area of the rectangle, 2b*2h it would increase the area by a factor of 4. 2b*2h is 4bh, bh=area so it's just the area times 4 which makes it correct.

B. ~p → ~q represents the inverse of the original conditional statement.  (True)

This means that if. (Okay, I don't have time, but if you don't understand something comment on it.)

C. q → p represents the original conditional statement.  (False)

D. ~q → ~p represents the converse of the original conditional statement. p → ~q represents the contrapositive of the original conditional statement (False)

sergij07 [2.7K]

Answer:

Maximum number of people is 35

Step-by-step explanation:

With a total of $160 you have to pay for the bus and all the people. The bus cost $90 so you subtract that from the 160 because you bought (or rented) the bus. Then you have $70 left to pay for everyone's tickets. If each ticket is $2 then you can buy 35 tickets in total because 70 divided by 2 = 35.
