Answer:

9.8

Step-by-step explanation:

Accordinng to the question,A bicyclist travelled for T = 0.7 hours at a constant speed of R = 14 kilometers (km) per hour. Use the formula D = R · T to find the total distance traveled in kilometers. Do not include the units in your answer.

We all know that speed= distance/ time and if you cross multiply,we will have distance as Time × Speed.

But since we were told to use D= R • T

And D is the distance

T is the time which is 0.7

R is the speed which is 14 kilometers per hour

Therefore, the total distance traveled by the cyclist is 14 × 0.7 = 9.8

Answer:

9.8

Step-by-step explanation:

We have the following formula:

D = R \times T

We have that:

R = 14, T = 0.7

So

D = 14*0.7 = 9.8

The total distance traveled in kilometers is 9.8

There is a 50% chance that the Fed will cut interest rates tomorrow. On any given day, there is a 67% chance the DJIA will incre
Amanda [17]

Answer:

3) 0.72

Step-by-step explanation:

The probability that tomorrow the Fed will cut interest rates (P(F)) OR the DJIA will go up (P(D)), is the sum of each event's individual probability minus their joint probability (Fed cutting interest rates AND the DJIA will going up, P(FD))

P(F+D) = P(F) +P(D) - P(FD)\\P(F+D) = 0.5 + 0.67 - (0.5*0.9)\\P(F+D) = 0.72

The probability that tomorrow the Fed will cut interest rates or the DJIA will go up is 0.72.

To determine if an ordered pair is a solution to a system of linear equations in two variables, __________.
vitfil [10]

Answer:

B

Step-by-step explanation:

When an ordered pair is a solution to a system of equations in two variables, it must mean that when you plug in the ordered pair into both equations, it must come out true (this is literally the definition of a solution to a system of equation). Technically, A is also facts, but B is a "more inclusive" facts so that's your answer. Hope this helps! :)

he radius of the base of a cylinder is 10 centimeters, and its height is 20 centimeters. A cone is used to fill the cylinder wit
Elis [28]
Volume of cylinder: V_{\text{cyl}}=\pi r^2h, where r is the radius and h is the height. This volume is \pi\times10^2\times20=2000\pi (cubic cm).

Volume of cone: V_{\text{cone}}=\dfrac13\pi r^2h, with the same variables denoting the same parameters. This volume is \dfrac13\pi\times5^2\times10=\dfrac{250}3\pi (also cubic cm).

The number of times it would take to fill the cylinder with water using the cone as a source would be

\dfrac{2000\pi}{\dfrac{250}3\pi}=24
