20% of 50....turn percent to decimal..." of " means multiply
0.20(50) = 10...so 10 is 20% of 50
Wat is help sheet, didn't help,
instructions unclear, got my calculator stuck in the ceiling fan
remember some simple exponential laws
and
first one
2nd one
third one
dunno wat to do with 'help sheet'
Answer:
x=10/3
Step-by-step explanation:
6x+5=3x+15
you subtract 3x from both sides
3x+5=15
you subtract 5 from both sides
3x=10
you divide 3 from both sides
x=10/3
i hope this helped!
Elouise and Marcus are 20 km apart. There is a lake due west of Elouise that is also 10√3 km due north of Marcus, so 22.36 km distance the bearing of Marcus from Elouise.
<h3>What is Pythagoras theorem?</h3>
According to the Pythagoras theorem, the square of the hypotenuse of a right-angled triangle equals the sum of the squares of the other two sides. The formula for this theorem is c² = a² + b², where c is the hypotenuse and a and b are the triangle's two legs. Pythagoras theory triangles are another name for these triangles.
At first assume a triangle, In the triangle, assume Elouise at the point A and Marcus at the point B, and the lake at the C point.
Given that,
Elouise and Marcus are 20 km apart (AB)
There is a lake due west of Elouise that is also 10√3 km due north of Marcus (BC)
Now, according to a Pythagoras theorem,
(AC)² + (AB)² = (BC)²
or, (AC)² = (BC)²- (AB)²
or, (AC)² = (10√3)² - (20)²
or, AC =
or, AC = 22.36 km
So, distance bearing of Marcus from Elouise is 22.36 km.
