Answer: C
Explanation:
Since tan(H) equals 1, we can conclude that angle H equals 45 degrees. Therefore, we know that it is a 45-45-90 triangle. Therefore, since both legs are equal, sin or cos doesn’t matter. Therefore, C is correct. (Draw it for yourself, it helps)
Answer: 77/10
Step-by-step explanation:
Convert to improper fractions and solve
2 1/5 --> 2*5+1/5 = 11/5
3 1/2 --> 3*2+1/2 = 7/2
Answer:
$319.50
see the procedure
Step-by-step explanation:
we know that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form or
Let
y ---> represents the total cost
x ---> represents the number of months
we have
so
The relationship between x, and y, represent a proportional variation
<u><em>Complete the table</em></u>
For x=9 months
substitute the value of x in the linear equation and solve for y
The answer is D good luck
