<u>Answer:</u>
Rhonda will not fall 264 times in 360 jumps.
<u>Solution:</u>
Given, The ratio of jumps to falls for ice skater Rhonda is 4 falls to every 15 jumps.
We have to find At this rate, how many times will she not fall in 360 jumps.
Now,
For 15 jumps → 4 falls
For 360 jumps → n falls
Now apply Chris cross method,
So, she falls 96 times in 360 jumps.
Then, number of times she will not fall = 360 jumps – 96 falls = 264 times.
Hence, Rhonda will not fall 264 times in 360 jumps.
Answer:
y = 0.36x + 4200.00
15100.00 miles.
Step-by-step explanation:
If the yearly cost for driving x miles is given by y dollars then the two ordered pairs to find the linear relation between x and y are (10000,7800) and (20000,11400).
So, the equation will be
⇒
⇒
⇒
⇒
⇒ y = 0.36x + 4200.00 ........... (1) (Answer)
Now, for y = $9636.00, from equation (1),
9636 = 0.36x + 4200
⇒ 0.36x = 5436
⇒ x = 15100.00 miles. (Answer)
Two straight lines or edges intersect
Answer:
The value of x = 2
Step-by-step explanation:
Given algebraic expression as :
Or, 10x + 6 = 4x + 18
Or, 10x - 4x = 18 - 6
Or, 6x = 12
Or, x =
∴ x = 2
Hence The value of x is 2 Answer
Answer:
n ≥ 5
Step-by-step explanation:
The money that Janie earns (E) must be greater than or equal to the cost (c) of the CD.
In symbols,
E ≥ c
2n + 3 ≥ 13 Subtract 2 from each side
2n ≥ 10 Divide each side by 2
n ≥ 5
Janie must do five or more chores to buy the CD.
