Fewer centimeters because there will be fewer centimeters

There would be fewer meter. Since 1 m=100 cm.

The mass of a freight train is 9.98 ⋅ 106 kilograms. The mass of an aircraft carrier is 7.3 ⋅ 107 kilograms. Approximately how m

shutvik [7]

Mass of freight train: 9.98 • 106
= 1057.88 kg
mass of aircraft carrier: 7.3 • 107
= 781.1 kg
difference: 1057.88 - 781.1
= 276.78 kg
= 2.7678 x 10^2

A ball is dropped from a height of 64 feet. Its height, in feet, can be modeled by the function h(t) = -167 + 64, where t is the

Oliga [24]

Answer:

Step-by-step explanation:

Known facts:

the ball dropped from a height of 64 feet
function $h(t) = -16t^{2} + 64$

First question:

the ball hits the ground when h(t) = 0, thus we get the equation

$-16t^{2} +64 = 0\\16t^{2} = 64\\t^{2} =4\\t = 2$

So the ball hits the ground in 2s

Second question

to find how long it takes the ball to fall 36 feet, we must set h(t) = 64 - 36 = 28

$-16t^{2} +64 = 28\\16t^{2} = 36\\t = \frac{6}{4} =1.5s$

So the ball hits the ground in 1.5s

Hope that helps!

Answer:

B. 2/3

Step-by-step explanation:

To solve this we have to take into account this axioms:

- The total probability is always equal to 1.

- The probability of a randomly selected point being inside the circle is equal to one minus the probability of being outside the circle.

Then, if the probabilities are proportional to the area, we have 1/3 probability of selecting a point inside a circle and (1-1/3)=2/3 probability of selecting a point that is outside the circle.

Then, the probabilty that a random selected point inside the square (the total probability space) and outside the circle is 2/3.
