Kyle ran the 200 yard dash in 40 seconds. How many feet can Kyle run each second?

2 answers:

7 0

Actually there are 3 feet in 1 yard so 200 yards equates to 600 feet. 600 feet divided by 40 seconds equals 15 feet per second.

Kyle can run 1.5 feet every single second.

Answer:

Step-by-step explanation:

Set up equations (L= Lisa; M = Maria; A = April; J = Jim)

L = 12M

A = 2J

Substitute x for Maria and 6x for Jim

L = 12x

A = 2(6x) = 12x

So, you get:

Maria = x

Jim = 6x

Lisa = 12x

April = 12x

Find the length of the height of the right trapezoid shown below, if it has the greatest possible area and its perimeter is equa

Artyom0805 [142]

Answer:

The height of the right trapezoid is $\frac{6}{5+\sqrt{3}}\ units$

Step-by-step explanation:

Let

x ----> the height of the right trapezoid in units

we know that

The perimeter of the figure is equal to

$P=AB+BC+CD+DH+HA$

we have

$P=6\ units$

$AB=BC=CH=HA=x$ ---> because is a square

substitute

$6=x+x+CD+DH+x$

$6=3x+CD+DH$ -----> equation A

In the right triangle CDH

$sin(30\°)=\frac{CH}{CD}$

$sin(30\°)=\frac{1}{2}$

Remember that $CH=x$

$\frac{1}{2}=\frac{x}{CD}$

$CD=2x$

$tan(30\°)=\frac{CH}{DH}$

$tan(30\°)=\frac{\sqrt{3}}{3}$

$\frac{\sqrt{3}}{3}=\frac{x}{DH}$

$DH=x\sqrt{3}$

substitute the values in the equation A

$6=3x+CD+DH$ -----> equation A

$CD=2x$

$DH=x\sqrt{3}$

$6=3x+2x+x\sqrt{3}$

$6=5x+x\sqrt{3}$

$6=x[5+\sqrt{3}]$

$x=\frac{6}{5+\sqrt{3}}\ units$
