Cones and polyhedrons both only have one base

Mathematics
1 answer:
Leona [35]3 years ago
8 0

Answer:

Cones only have one base but polyhedrons can have multiply surfaces that can be used as a base. ... A polyhedron is a three-dimensional object with flat two dimensional faces such as a cube. So it can have multiple bases depending upon which side is placed horizontally on the ground.

which has greater cenetic energy a car traveling 30.0 km/hr or one twice as heavy traveling at 15 km/hr?​
iVinArrow [24]

Answer:

30 km/h car

Step-by-step explanation:

From analysis the   car traveling at 30 km/h has greater kinetic energy

we can deduce it from the expression of kinetic energy which is

KE=\frac{1}{2} mv^2

Assuming the mass m= 1 kg

 

For the 30 km/h

KE=\frac{1}{2}*1*30^2 \\\\KE=\frac{1}{2}*1*900\\\\\KE=450 J

   

For the 15 km/h

KE=\frac{1}{2}*2*15^2 \\\\ KE=\frac{1}{2}*2*225 \\\\\ KE=\frac{1}{2}*450 J\\\\\ KE=225 J

Though the kinetic energy is a function of mass and velocity, but from our analysis the faster moving object has more KE

A delivery truck is transporting boxes of two sizes: large and small. The large boxes weigh 50 pounds each, and the small boxes
skad [1K]
So this is how we are going to solve for the given problem above.
Given that x = number of large boxes
and 120-x = number of small boxes.
So here is the solution:
50x + (120-x)20 = 4050
50x + 2400 - 20x = 4050
30x + 2400 = 4050
30x = 4050 - 2400
30x = 1650 <<divide both sides by 30
x = 55.
Therefore, there are 55 large boxes
120 - x = small boxes
120 - 55 = 65 small boxes.
Hope this is the answer that you are looking for.
Let me know if you need more help next time!

What is the slope of (8,3) and (-4,-6)?
Nonamiya [84]

<u>Answer:</u> The slope of the line formed by these two points is \frac{3}{4}

<u>Step-by-step explanation:</u>

To calculate the slope, we use the formula:

Slope=\frac{y_2-y_1}{x_2-x_1}

For the coordinates given:

x_1=8\\y_1=3\\x_2=-4\\y_2=-6

Putting values in above equation, we get:

Slope=\frac{(-6-3)}{(-4-8)}\\\\Slope=\frac{-9}{-12}\\\\Slope=\frac{3}{4}

Hence, the slope of the line formed from these two coordinates is  \frac{3}{4}
