A cone has a radius of 1 foot and a height of 2 feet. How many comes of Liquid would it take to fill a cylinder with a diameter

of 2 feet and a height of 2 feet

find the volume of the cone:

1/3 pi r squared × h

1/3 pi (1) squared × 2

= 2/3 Pi (feet cubed)

find the volume of the cylinder:

pi r squared × h

(the radius is 1 foot because its half the diameter which is 2 feet)

pi (1) squared × 2

= 2 Pi (feet cubed)

2 Pi is÷ 2/3 Pi

= 3

therefore it will take 3 cones of liquid to fill a cylinder with a diameter of 2 and height of 2

The probability of selecting one student who is both from math and science is 1/10

There are the total number of student = 300

Out of which,the number of students who are only in Maths  = 120

The number of students who are only in Science  = 50 and  the students who are not from any subject = 100

<h3>What is the formula for the total students?</h3>

Total no of students=science student+math students +none

Therefore,the number of student who are from both math and science = Total student - Math student (only) - science student (only) - None

= 300 - 120 - 50 - 100

= 30

That is, there are 30 students who are both from science and math,

Thus, the probability of selecting one student who is both from math and science = 30/300 = 1/10

The product of some negative number and 3 less than twice that number is 209. find the number
zepelin [54]
The negative number would most likely be -19/2

let the negative number be x,
3 less than twice that negative number would be (2x-3)
hence,
equation form
x multiply by (2x-3) equals to 209
it would result in equation
2x^2-3x=209
2x^2-3x-209=0

hence using quadratic eqn
x=11 ( rej since qn stated x is a negative number)
x=-19/2

A city planner wants to build a ramp onto a highway. The vertical distance that the ramp goes up is 160ft. The length of the ram
Dimas [21]

Answer:

300 ft

Step-by-step explanation:

Given that a city  planner wants to build a ramp onto a highway. The vertical distance that the ramp goes up is 160ft. The length of the ramp is 340ft and represents the hypotenuse of a right triangle.

i.e. the triangle formed is a right one with hypotenuse  340 ft and one side 160ft.  The other side is the horizontal distance the ramp will cover say x

Then by Pythagorean theorem we get

340^2 = 160^2+x^2\\x^2 =(340+160)(340-160)\\\\x^2 =90000\\x =300 ft

Thus horizontal distance the ramp will cover = 300 ft.
