A car that travels 20 miles in \frac{1}{2} 2 1 ​ hour at constant speed is traveling at the same speed as a car that travels 30 miles in \frac{3}{4} 4 3 ​ hour at a constant speed.

Answers

Answer 1

Step-by-step explanation:

If distance is 20 miles and time is (1/2) h. Its speed is given by :

[tex]v=\dfrac{d}{t}\\\\v=\dfrac{20\ miles}{1/2\ h}\\\\v=40\ mph[/tex]

If the distance is 30 miles and the time is (3/4) hours. Its speed is given by :

[tex]v=\dfrac{d}{t}\\\\v=\dfrac{30\ miles}{3/4\ h}\\\\v=40\ mph[/tex]

So, the rate or the speed ib both the case is constant.

5x +2y = 12
5x −2y = 28

Answers

i used elimination. so you start by adding the 2 equations. |5x+2y=12+5x-2y=28| you end up getting |10x=40| the 2y’s cancel out because on is positive and one is negative. then you divide each side by 10. |x=4| you plug this in for x in the first equation. |5x+2y=12|=|5(4)+2y=12| multiply parentheses. |20+2y=12| subtract 20 from each side. |2y=12-20| add like terms. |2y=-8| divide by 2 on each side. |y=-4|. sorry for the long explanation. in conclusion, x=4 and y=-4, or (4,-4)

What is the volume of a cone with a radius of 4 centimeters and a height of 5 centimeters? please help

Answers

Answer:

V = [tex]\frac{80\pi }{3}[/tex]

Step-by-step explanation:

Using the equation for finding the volume of a cone

V = [tex]\pi[/tex]r²[tex]\frac{h}{3}[/tex]

Were "V" is Volume, [tex]\pi[/tex] is pi, r² is radius to the second power, and [tex]\frac{h}{3}[/tex] is height divided by 3.

We can fill in the missing components to find "V" as in for Volume.

V = [tex]\pi[/tex]4²[tex]\frac{5}{3}[/tex]

Now let's simplify

V = 16[tex]\pi \frac{5}{3}[/tex]

Now simplify for the last time

V = [tex]\frac{80\pi }{3}[/tex]
