Answer:

the truck with the fewest number of miles per gallon is TRUCK D with a distance of 9miles per gallon

Step-by-step explanation:

Four trucks were used to make deliveries.

Truck A 45 3

Truck B 24 2

Truck C 14 1

Truck D 36 4

Which truck drove the fewest number of miles per gallon of gas?

To calculate for mile per gallon for each truck = miles/gallon

Truck A 45 3 =45/3 = 15miles/gallon

Truck B 24 2 = 24/2 =12miles/gallon

Truck C 14 1 = 14/1 = 14miles/gallon

Truck D 36 4= 36/4 = 9miles/gallon

the truck with the fewest number of miles per gallon is TRUCK D with a distance of 9miles per gallon

Im a lil stuck on this :v
12345 [234]

Answer:

C-----> x<-7

Step-by-step explanation:

first u do this to turn x in positive and consequently change the > to an <:

(-1).(-4x)>28.(-1)

so:

4x<-28

x<-7

# when multiplying each side by (-1), you have to change the symbol (>) to an (<), or (<) to an (>)

The length of the diagonal of a wooden cube is 24 cm. The cube is cut into the cylinder of the
jek_recluse [69]

The biggest possible volume of the cylinder will be 2089.497\hspace{1mm}\text{cm}^3.

<h3>What will be the diameter and height of the cylinder obtained from a cube and what are the formulas for the diagonal of a cube and the volume of a cylinder?</h3>
  • If a cylinder with the biggest possible volume is cut inside the cube, the height of the cylinder and the diameter of the cylinder will be equal to the side length of the cube.
  • For example, consider the following figure in which the cylinder is cut inside of the cube and since the side length of the cube is x, the diameter and the height of the cylinder are also x
  • If the side length of a cube is x unit, then its diagonal will be x\sqrt{3} unit.
  • The formula for the volume of a cylinder is V=\pi r^2h, where r is the radius and h is the height of the cylinder. If d is the diameter, then r=\frac{d}{2}.

Now, given that the diagonal of the cube is 24 cm. So, if the side length of the cube is x cm, then we must have

x\sqrt{3}=24\\\Longrightarrow x=\frac{24}{\sqrt{3}}\\\Longrightarrow x=8\sqrt{3}

Thus, the side length of the cube is 8\sqrt{3} cm.

So, the height of the cylinder with maximum volume will be h=8\sqrt{3} cm and the diameter will be d=8\sqrt{3}cm i.e. the radius will be r=\frac{d}{2}=\frac{8\sqrt{3}}{2}=4\sqrt{3} cm.

So, using the above formula for the volume of a cylinder, we get

V=\pi r^{2}h=\pi\times (4\sqrt{3})^2\times 8\sqrt{3}=2089.497\hspace{1mm}\text{cm}^3.

Therefore, the biggest possible volume of the cylinder will be 2089.497\hspace{1mm}\text{cm}^3.

I need help, it’s a true or false question
marusya05 [52]

Answer:

The answer to this is False, False, True.

Step-by-step explanation:

A is false because WAU is an obstute angle, which can't be 55 degree.

B is flase because YAU is actually the angle that is 55 degree, not 35 degree.

C is true because WAX is congruent to YAU and it is 55 degree.
