URGENT!!! Amy, on a jog, runs in a straight line for 3 miles. She then changes direction, heading 50 degrees to the right and ru

Mariana [72]

Answer:

8.2500000000 miles

Step-by-step explanation:

I drew a triangle to illustrate the reference triangle.

So, Amy ran from summit A for 3 miles then turned to her right by 50 degrees (creating angle B of 130 degrees), and runs for another 6 miles.

Based on the Cosines Law, we have:

$cos(B) = \frac{c^{2} + a^{2} - b^{2} }{2 * c * a}$

If we isolate b, we have the following formula.

$b = \sqrt{a^{2} + c^{2} - 2 * a * c * cos(B) } \\ \\b = \sqrt{6^{2} + 3^{2} - 2 * 6 * 3 * cos(130) } = 8.25$

So, as she stops at summit C, she's 8.25 miles away from her starting point.

Tom [10]

Answer:

(3x^2-5x-5)/(x^2+x) <--- answer

Step-by-step explanation:

3x/(x+1) - 5/x = (3x^2 - 5(x+1) )/[ x(x+1) ]

= (3x^2 - 5x - 5)/(x^2 + x)

А.

mylen [45]

Answer:

E. $\frac{2}{5} a^{3}$

Step-by-step explanation:

$\sqrt{\frac{36a^{8} }{225a^{2} }}$

√36 = 6

√225 = 15

√a² = a

√a⁸ = a⁴

We now have;

$\frac{6a^{4} }{15a}$

$\frac{2}{5} a^{3}$

Dalia earns $108.75 for working 15 hours a day as a holiday helper wrapping presents. At this rate, how much money will she make

Amanda [17]

Calculate the proportion:

108.75 : 15 = x : 19

x = (108.75 × 19) / 15

x represents the amount of money she would get daily

Plug this into the calculator
