The midpoint of gh is m(4,-3). One endpoint is G(-2,2). Find the coordinates of endpoint H

Mars2501 [29]

Answer:

Step-by-step explanation:

(-2 + x)/2= 4

-2 + x = 8

x = 10

(2 + y)/2 = -3

2 + y = -6

y = -8

(10, -8) for endpoint H

A realtor a lock box to store the keys to a house that is for sale. The access code for the lock box consists of five digits. Th

guapka [62]

Answer:

36,000 possible codes.

Step-by-step explanation:

I guess you want the total number of arrangements possible.

The first digit can be any number from 0 to 8. the middle numbers must each be any number from 0 to 9 and the last digit must be 2,4,6 or 8.

So the number of arrangements possible = 9 * 10 * 10 * 10 * 4

= 36,000.

A 600-ft tall building is represented by a 30-in. tall model.

alexdok [17]

$\huge\boxed{19\ \text{inches}}$

First, find the scale factor by dividing the first building's real-life height by its model height.

$\frac{600}{30}=\frac{60}{3}=20$

Now, we'll write an equation to find the model height of the second building.

$r=20m$

Here is an equation where $r$ represents the real-life height of a building, $20$ represents the scale factor, and $m$ represents the model height of the same building.

Fill in the information we already know.

$380=20m$

Divide both sides by $20$ .

$\frac{380}{20} = \frac{20m}{20}$

$\large{\boxed{19}}=m$

So, the model height of the second building is $19$ inches.

Addie walked 2 1/2 miles in 45 minutes. Suzie covered 2 2/5 miles in 2/3 of an hour.

N76 [4]

Answer:

Suzie's speed was 3.6 mph

Step-by-step explanation:

we know that

The speed is equal to divide the distance by the time

Let

s ----> the speed in mph (miles per hour)

x ----> the distance in miles

y ----> the time in hours

$s=\frac{x}{y}$

Find Suzie's speed

we have

$x=2\frac{2}{5}\ mi$

$y=\frac{2}{3}\ h$

substitute

$s=2\frac{2}{5}:\frac{2}{3}$

Convert mixed number to an improper fraction

$2\frac{2}{5}=2+\frac{2}{5}=\frac{2*5+2}{5}=\frac{12}{5}$

substitute

$s=\frac{12}{5}:\frac{2}{3}=\frac{36}{10}=3.6\ mph$
