Part A- DISCOUNT-SALES TAX--- 42.5
WITH TAX-- 45.05
part b- the tip is... 10.5
part c- 11.11
Answer:
step 2
Step-by-step explanation:
step 1 is good: -5x + 8 = 7
step 2 (error): meant to subtract 8 on both sides
-5x = 7 - 8
-5x = -1
step 3 : divide -5 on both sides
x = -1 / -5
x = 1/5
Answer:
Developed Length
Step-by-step explanation:
A developed length is the length along the centre line of a circular shape.
From the question, the degree of bend is 90°
Also, from the question; the length of an arc of 1 quadrant.
1 quadrant = 90°
And the degree of bend = 90° (from the question)
So, it's safe to say 1 quadrant = the degree of bend = 90°
A small change in 90° will move change the quadrant to another quadrant.
So, at exactly 90° (or other multiples of 90° which are 180°, 270° and 360°), it is at its developed length.
Answer:

Step-by-step explanation:
Represent the first half with F and the second with S
We have that:
--- From the first statement
--- From the next statement
Required
Determine the ratio of S to the total point
First, we need to determine the value of S
Substitute 9 for F in



Next, we determine the total points



The ratio of S to total is: (Represent total with T)

Divide both ration by 3


<em>Hence, the ratio is 5 to 8</em>
