Answer:
In two similar geometric figures, the ratio of their corresponding sides is called the scale factor.
To find the scale factor,we need to follow some rules:
locate two corresponding sides, one on each figure.
Write the ratio of one length to the other to find the scale factor from one figure to the other
Answer:
a.12/13
Step-by-step explanation:
- FORMULA: sine of an angle in a triangle is given by,
- here, in the given triangle PQR, for angle 'p'
opposite side= QR
adjacent side= PQ
hypotenuse=PR
- Therefore, sine of angle p=
- Thus, by using the above given formula, the sine of angle p in the triangle PQR is 12/13.
- hence, the trigonometric formulas as mentioned above should be remembered for sure to solve these type of problems
Your answer is D.
The jeans are 40% off (because you add 20% more).
And the original cost of the jeans is $30.
You could have done:
30 · 0.40 = 12 (Find 40% of $30, then subtract 30 by 40% of 30 to get the new sale price]
30 - 12 = 18
1 - 0.40 = 0.60 (You subtract 1 by 0.40 to get 0.60, which is the % of the original price that you have to pay)
30 · 0.60 = 18
Company B; the ratios of cost to weight are equivalent.
Step-by-step explanation:
Step 1:
In the equation, 
k is the constant of proportionality.
If the values are in accordance with , the values of k will be constant for all the values.
So we determine the values of k for both the companies and see which has a constant k.
If 
. In these tables, y is the total cost and x is the weight in lbs.
Step 2:
For company A,
when 
when 
when 
For company B,
when 
when 
when 
So company B has a constant value of 
.
