Tina bought 15.25 gallons of gasoline at a price of $2.31 per gallon. What is the total cost of the gasoline rounded to the near

To find the total cost, we must multiply the amount that was bought by the price of each individual item. So we need to multiply the price of one gallon by how many gallons Tina bought:

15.25*2.31=35.227

However, the question says to round to the nearest hundredth, so we must round up. Therefore the total amount Tina paid for the gasoline was $35.23.

product: -48  sum: 2

8, -6

x^2 +8x - 6x - 48

=> x(x+8) -6(x+8)

=> (x+8)(x-6)

Jesse is looking for the volume of the cone below, and she is using the formula V=(1/3)Bh. Which of the following is the value o
Sidana [21]

Answer:

B =  \pi *r^2

(Base of the cone)

Step-by-step explanation:

The volume of the cone is always 1/3 of the volume of a cylinder with the same radius and height.

Volume of the cylinder

V_cylin = ( \pi *r^2 )* h

Where

r is the radius

h is the height

This means the volume of the cone is equal to

V_cone = (1/3)* ( \pi *r^2 )* h

By looking to the equation of the problem

V=(1/3)Bh

We can easily deduce that

B =  \pi *r^2

(Base of the cone)

Which expression represents the volume, in cubic units, of the shaded part of the sphere? four-thirdsπ(103) four-thirdsπ(43) fou
oee [108]

The volume of the shaded part in cubic units is  4/3π(20)³ -  4/3π(4)³

<h3>Volume of composite object</h3>

The sphere is a a solid 3-dimensional object. THe formula for calculating its volume is expressed as:

V = 4/3πr³

where:

r is the radius of the sphere

<u>For the outer sphere:</u>

V = 4/3π(20)³

<u>For the inner sphere:</u>

V = 4/3π(4)³

The volume of the shaded part in cubic units is  4/3π(20)³ -  4/3π(4)³

I need help ASAP................................
Anestetic [448]

Answer:

x = -1

Step-by-step explanation:

-2(x - 5) = 12

-2x + 10 = 12 (this is the mistake, -2 times -5 = + 10)

-2x = 12 - 10

-2x = 2

x = 2/(-2)

x = -1
