EFGH is a parallelogram. Find the measure of FG.

Serggg [28]

Answer:

Step-by-step explanation:

FG = EH ( being opposite sides of parallelogram)

3z + 8 = 5z - 14

5z - 3z = 8 + 14

2z = 22

z = 11

Now

FG = 3z + 8 = 3 *11 + 8 = 33 + 8 = 41

Hope it will help :)❤

What number makes the equation true? 82 − <br> − 33 = 35

-BARSIC- [3]

First you should subtract the first numbers. 82-33=49
Next, you need to subtract 49- the product, which is 49-35=14
Finally, check your work. 82-14-33=35

I think this is what you mean, at least?

Justin Verlander of the Astros threw a pitch 100 miles per hour. How many seconds did it take to get to home plate. The plate is

castortr0y [4]

It will take 0.4 seconds to get to the home plate.

Given:

The speed of the pitch thrown by Justin is 100 miles per hour

The distance of home plate from the pitching rubber is 60.5 feet

To find:

The time taken by a pitch to reach the home plate

Solution:

The distance home plate from the pitching rubber = d = 60.5 feet

$1 mile = 5280 feet\\1 foot=\frac{1}{5280} mile\\60.5 feet=60.5 \times \frac{1}{5280} mile=\frac{60.5}{5280}miles$

The speed of pitch thrown by Justin = s = 100 miles/hr

The time taken by a pitch to reach the home plate = t =?

The speed of the moving object is given by dividing the distance covered from the time taken to cover that distance.

$Speed=\frac{Distance}{Time}\\s=\frac{d}{t}\\100 miles/hr=\frac{\frac{60.5}{5280}miles}{t}\\t=\frac{60.5}{5280}miles\times \frac{1}{100 miles/hr}\\= 0.000114583 hr$
