A rectangle is a four-sided flat shape where every angle is a right angle<span> (90°).

</span> $QRST = 90^0$

$5x + 30 = 90$

$5x = 60$

$5x = 60 / 5$

$x = 12$

If QRST is a rectangle then Q = 90°.

Threfore

5x + 30 = 90 |subtract 30 from both sides

5x = 60 |divide both sides by 5

x = 12

Samantha and Mia each left Julia’s house at the same time. Mia walked north at 7 kilometers per hour. Samantha ran west at 11 ki

Lena [83]

Mia walked 7km/h so after 1 hour, she is 7 km north of the house of Julia

Samantha walked 11km/h so after 1 hour, she is 11 km west of the house of Julia.

The points where Mia and Samantha are after 1 hour , and the house of Julia form a right triangle with sides 7 and 11 km. The distance between the girls, is the hypotenuse of his triangle.

by the pythagorean theorem:

$MS= \sqrt{ 7^{2} + 11^{2} }= \sqrt{49+121}= \sqrt{170}= 13 (km)$

Answer: 13 km

Explain why you might want to write very large and very small numbers like the ones in the example problem in scientific notatio

slava [35]

Answer:

Extremely large and small numbers that have many zeros are long to write and take up a lot of room. So, by using scientific notation a number can be written shorter. For example, numbers such as 295,000,000,000 can be shortened to 2.95x $10^{11}$ . This is easier to write and understand. This is why the scientific notation is used over standard.
