You are the administrator of an annual essay contest scholarship fund. This year a $80,000 college scholarship is being divided

Hatshy [7]

Answer:

Runner Up Amount=$16,000

Winner Amount=$64,000

Step-by-step explanation:

Amount of the college's scholarship=$80,000

The fund is being divided between the top two contestants so that the winner receives four times as much as the runner-up.

Therefore: we can say it is being divided into 5 parts where the winner gets 4 parts and the runner up gets 1 part, i.e in the ratio 4:1.

Runner Up Amount $=\dfrac{1}{5}X\$ $80,000=\$16000$

Winner Amount $=\dfrac{4}{5}X\$ $80,000=\$64000$

The winner gets $64,000 and the runner up gets $16,000.

If f(x) = V7x + 31 , find f(0).

Arte-miy333 [17]

Answer:

f(0) = 31

Step-by-step explanation:

We are given the following function:

$f(x) = \sqrt{7x} + 31$

f(0).

This is the value of f when $x = 0$ . So

$f(0) = \sqrt{7*0} + 31 = \sqrt{0} + 31 = 0 + 31 = 31$

So f(0) = 31

An airplane started at point K, travelled 560 miles to point L, adjusted its route and travelled another 575 miles to point M. I

S_A_V [24]

Answer:

Step-by-step explanation:

Using the cosine theorem:

$c^{2} =a^{2} +b^{2} -abcos\beta$

$952^{2} =560^{2} +575^{2} -560*575cos\beta$

$\beta =cos^{-1} (\frac{560^{2}+575^{2}-952^{2} }{2*560*575} )$

The angle is 114.014 degrees if we substract 90 degrees it means that at point L the plane changed its angle by 24 degrees
