Answer:
36.45 cm
Step-by-step explanation:
You can automatically assume that if it was 20% cut off, Wendy's hair would've been 36 cm. Multiply 45 by 0.19 to get 8.55 since that is how much Wendy's hair is being cut off. Subtract that number from 45 to get your final answer which is 36.45 cm.
Answer:
21,550

Answer: Ana will hit the water after 3 seconds.
Step-by-step explanation:
The exercise gives you the following function which models Anna's height above the water (in meters) after diving "x" seconds:
You can rewrite the function with 
:
In order to calculate the number of seconds Ana will hit the water after diving, the procedure is:
- Substitute 
into the function:
- Solve for "x".
By the Zero Product Property, you know that if 
, then 
or 
.
Then you get:
- Choose the positive value (
)
Then, Ana will hit the water after 3 seconds.
4b+2c=36, solve for b, subtract 2c from both sides
4b=36-2c divide both sides by 4
b=9-0.5c
Then we are told that:
7b+3c=59, using b=9-0.5c we get:
7(9-0.5c)+3c=59 perform indicated multiplication on left side
63-3.5c+3c=59 combine like terms on left side
63-0.5c=59 subtract 63 from both sides
-0.5c=-4 divide both sides by 0.5
c=8
So each souvenir cup costs $8.
(and each bag of cotton candy is $5)
