For each question we must apply the Pythagorean theorem and clear the value of x.
question 5
x = root (14 ^ 2 + 16 ^ 2)
x = root (452)
x = 2raiz (113)
question 6
x = root (8 ^ 2 + 15 ^ 2)
x = 17
question 7
x = root (12 ^ 2 + 12 ^ 2)
x = root (2 * (12 ^ 2))
x = 12raiz (2)
question 8
x = root (18 ^ 2 - 9 ^ 2)
x = root (243)
x = 9raiz (3)

Answer:

$\alpha =107.4^{o}$

Step-by-step explanation:

$15=\frac{\pi (8)\alpha }{180}$

$\alpha =\frac{(15)(180)}{8\pi } =\frac{2700}{25.13}=107.4$

A. $6800 + $1360= $8160 total cost

b.
$68.85 each * 165 bracelets = $11360.25
$11360.25- $8160 total cost = $11278.75 profit

$11278.75 profit/$8160 total cost= 1.38218
1.38218= about 138%

Final answer: 138%
Warning: This answer will vary if you find the percent over cost (not including duty).

I need some help with this one. Please give it a go! Thank you for your time!

Answer:

y = 4x - 3

Step-by-step explanation:

When we re-write the given equation into its slope-intercept form, it will like this:

y = (-1/4)x - 6

This line has a slope equal to -1/4 so the slope of the required line has a slope of +4 (perpendicular to the given line). Use this new slope and the given point P0(-1, -7) into this equation:

y - y0 = m(x - x0) ---> y + 7 = 4(x + 1)

Rearranging the terms into its slope-intercept form, we get

y = 4x - 3

Write an inequality that represents the following problem. There are two cell phone plans available from Cell Phones R Us compan

Sergio [31]

If PLAN A is cheaper than PLAN B then,
P (A) subtract 29.95 from both sides)
-0.04t < -10 (divide both sides by -0.04)
t > 250
So plan A is cheaper than plan B when you send more than 250 texts.
Hope it helps.

Answer:

A, B, C, E, and F

To solve this problem, you should make sure to find the equation first. Start by doing rise/run with your two given points on the graph. From the point (-1,1) you rise 4 and then run 16 over to the point (3,2). That gives us a slope of 4/16 which can then be simplified to 1/4. That means that letter F tells us the equation of the line is y= 1/4x + 5/4.

From there you want to check your points, (3,2) and (-1,1). The first number is always x and the second number is always y. So you plug the point numbers into the equation we just found to see if they work. In the photos I inserted are how to do this step.

Once you have checked your points and you know for sure they're solutions, that gave you letters A and B. Since the point (1, 3/2) is also given in one of the answers we should check that point as well. (Also done in one of the photos) Since the point came out correctly that gives us letter C and also tells us there is more than 2 solutions. This means that letter E is also correct.

Hope this helped!
