Find the values of x y and z

andrey2020 [161]

9514 1404 393

Answer:

x = 18√2
y = 18√3
z = 36

Step-by-step explanation:

These "special" right triangles have side length ratios that it is useful to remember.

<u>45°-45°-90° triangle</u>

Sides have the ratios 1 : 1 : √2. That is, x is √2 times as long as the side length shown as 18.

x = 18√2

<u>30°-60°-90° triangle</u>

Shortest to longest, sides have the ratios ...

1 : √3 : 2

That is, y is √3 times the length of the side marked 18, and z is 2 times the length of the side marked 18.

y = 18√3

z = 2·18 = 36

- In 1927, Charles Lindbergh had his first

Hitman42 [59]

Answer:

Each hour he fly 107.76 miles

Step-by-step explanation:

we know that

Charles Lindbergh flew 3,610 miles in 33.5 hours

To find out the unit rate, divide the total distance by the total time

$\frac{3,610}{33.5}= 107.76\frac{miles}{hour}$

therefore

Each hour he fly 107.76 miles

Simplify the scalar multiplication on the matrix.

Romashka-Z-Leto [24]

Answer:

third option

Step-by-step explanation:

Given

3 $\left[\begin{array}{ccc}-2&5\\1&0\\\end{array}\right]$

Multiply each element in the matrix by 3

= $\left[\begin{array}{ccc}3(-2)&3(5)\\3(1)&3(0)\\\end{array}\right]$

= $\left[\begin{array}{ccc}-6&15\\3&0\\\end{array}\right]$

A swimming pool at a park measures 9.75 meters by 7.2 meters.

neonofarm [45]

Answer:

Part a) The area of the swimming pool is $70.2\ m^2$

Part b) The total area of the swimming pool and the playground is $105.3\ m^2$

Step-by-step explanation:

Part a) Find the area of the swimming pool

we know that

The area of the swimming pool is

$A=LW$

where

L is the length side

W is the width side

we have

$L=9.75\ m\\W=7.2\ m$

substitute the values

$A=(9.75)(7.2)$

$A=70.2\ m^2$

therefore

The area of the swimming pool is $70.2\ m^2$

Part b) The area of the playground is one and a half times that of the swimming pool. Find the total area of the swimming pool and the playground

we know that

To obtain the area of the playground multiply the area of the swimming pool by one and a half

$\frac{1}{2}(70.2)=35.1\ m^2$

To obtain the total area of the swimming pool and the playground, adds the area of the swimming pool and the area of the playground

$70.2\ m^2+35.1\ m^2=105.3\ m^2$

therefore

The total area of the swimming pool and the playground is $105.3\ m^2$
