Answer:

Step-by-step explanation:

If the upper triangle has a right angle at Island C, we need only use the Pythagorean Theorem to find x:

(10 mi)^2 + (20 mi)^2 = x^2, so that

x^2 = 100 mi^2 + 400 mi^2 = 500 mi^2, which reduces to

x = +10√5 mi

Note that the shortest side (10 mi) is adjacent to a 30 degree angle. Thus, the upper triangle is a 30-60-90 triangle, meaning that the Pythagorean Theorem DOES apply here.

Next time, please incude ALL of the verbal instructions. Thank you.

Carlos find the absolute value of -5 3/10 and then find is the opposite of his answer Jason finds the opposite of -5 3/10 and th

a_sh-v [17]

we know that

$5 \frac{3}{10}= \frac{5*10+3}{10} = \frac{53}{10}$

Step 1

Carlos's method

1) Find the absolute value of $-\frac{53}{10}$

$\left|-\frac{53}{10}\right|=\frac{53}{10}$

2) Find the opposite

$opposite=-\frac{53}{10}$

Step 2

Jason's method

1) Find the opposite of $-\frac{53}{10}$

$opposite=\frac{53}{10}$

2) Find the absolute value

$\left|\frac{53}{10}\right|=\frac{53}{10}$

Step 3

Compare the answers

$\frac{53}{10} > -\frac{53}{10}$

therefore

The answer is

The greater value is obtained with the method of Jason

Explain in 1-2 paragraphs how design and problem solving are related. provide an example of a problem situation in which design

luda_lava [24]

When comparing and contrasting, it's always good to think about what your doing it with.
I'm not going to give to a full paragraph, but I'd love to help get one started for you!

First, let's look at the definition of both terms:

-Design: "purpose, planning, or intention that exists or is thought to exist behind an action, fact, or material object" ~ Google

-Problem Solving: "Taking different approaches to finding a solution to the problem, or task at hand."

Now, let's compare. When designing things, you in a way, are problem solving to figure out how to create or build a solution to a problem. This can be through trial and error, or complex thinking.

I hope this helps, and good luck! :)
