Answer:
Step-by-step explanation:
Let the numbers be x,y, where x>y
The geometric mean is
The Arithmetic mean is
The ratio of the geometric mean and arithmetic mean of two numbers is 3:5.
We can write the equation;
or
l
and
or
Make y the subject in equation 2
Put equation 3 in 1
When x=1, y=10-1=9
When x=9, y=10-9=1
Therefore x=9, and y=1
The ratio of the smaller number to the larger number is
50 * 3 = 150 and 150 * 3 = 450
So the answer is b 150
Answer:
33g
Step-by-step explanation:
10% of 30g is 3g so add 30g to 3g and you get 33g.
AB=24 AC=24. The triangle is SSS Which means all sides are congruent so just setting AB = AC then finding x. Then plugging it in u get your answer
Answer:
123
Step-by-step explanation:
A+C and E+G will equal 180 separately. Because the lines are parallel we can see that C is equal to G so we can exchange them. Next we have to fill in an equation by using the two equations given which would be 180=9x+15+5x-3 Now solve it
Add alike terms: 180= 14x+12
Subtract 12 to both sides to get operations alone: 168=14x
divide by 14 to get X alone which is 12=x
Now fill in x
9(12)+15= 123
