PLZ HELP Find the value of x that makes ΔXYZ~PQR

Galina-37 [17]

Answer:

x = 8

Step-by-step explanation:

$\triangle XYZ \sim\triangle PQR... (GIVEN) \\\therefore \frac{XY}{PQ} = \frac{YZ}{QR}.. (csst) \\\therefore \frac{20}{30}= \frac{x+6}{21}\\\therefore \frac{2}{3}= \frac{x+6}{21}\\\therefore \frac{2\times 21}{3}= {x+6}\\\therefore 14= {x+6}\\\therefore 14-6= {x}\\\therefore 8= {x}\\\huge \orange{\boxed {\therefore x = 8}}$

1) A train travels 25 miles in 1/5 of an hour whats the trains speed in miles per hour?

Radda [10]

Answer:

<em>Hope this helps! ↓</em>

Step-by-step explanation:

1.) 90 Km/h. Example: What is the speed of a cheetah that travels 112.0 meters in 4.0 seconds? ... Speed of the cheetah in miles per hour 28m 1 mile 3600 s 63 miles

2.) y=kx is the direct variation formula. Inserting the information and variables from this scenario we get h = kn.

12 = k*(10) First solve for 'k', the constant of proportionality by dividing by 10.

1.2 = k

Next write the equation using this k and the h & n.

h = 1.2*n

Now we want to find the height if we have 24 books so plug 24 in for n.

h = 1.2 * 24

h = 28.8 inches

3.) 10/3
