Answer:a=10
Step-by-step explanation:
I don’t know how to explain this in detail but I hope these notes and work help you.
The answer is C. all the savings added up is $450. 1 percent of 3,470 is $34.7. $450/$34.7 is 12.9682997, which rounded up is 13.
By solving a system of equations, we will see that m measures 12 units.
<h3>
How to get the measure of m?</h3>
Notice that we have 3 right triangles.
Then we can write the equations:
cos(a) = 6/m
For the small triangle on the left, where m is the hypotenuse.
cos(a) = m/(6 + 18)
For the larger triangle (the one composed of the two triangles).
Where in both equations, angle "a" is the one in the top left.
Then we have the system of equations:
cos(a) = 6/m
cos(a) = m/(6 + 18)
Then we can write:
6/m = m/(6 + 18)
If we simplify the expression, we get:
6*(6 + 18) = m^2
6*(24) = m^2
144 = m^2
√144 = m = 12
Then we conclude that m measures 12 units.

Answer:
30% increase
Step-by-step explanation:
1.43 - 1.10 = 0.33
0.33 = 30% of 1.10
Answer:
The distance from Greentown to Glenavon is D1 = g*(15+x) miles downstream.
The distance from Glenavon to Cambria is D2 = g*(15-x) miles upstream.
The difference D1 - D2 is 2 miles, according to the condition.
It gives you an equation g*(15+x) - g*(15-x) = 2, which you can easily solve and find "x", the rate of the current. x = 1/g miles per hour.
