<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:
2250 ml
Explanation:
1 day = 0.45 L
5 days = 0.45 x 5
=2.25 L
1 L = 1000 ml
2.25 L = 2250 ml
1. Observe Problem
It can be flipped on the x axis and y axis
so, Flipped on the x axis, it becomes:
<h2><u><em>
(0,-7)</em></u></h2>
So, flipped on the y axis, it becomes:
<h2><u><em>
(0,7)</em></u></h2>
Which is the same thing
12 boys : 26 students
divide by 2 and you get
6 : 13
this can’t be divided anymore so the ratio in simplest form is 6:13
By algebraic handling we find that the unique solution of the system of linear equations is: (x, y, z) = (- 2, 4, 3). (Correct choice: A)
<h3>What is the nature of a system of linear equations?</h3>
If the system of equations has no solutions, then the determinant of the dependent coefficients of the system of linear equations must be zero. Let see:
This determinant can be determined by Sarrus' rule:
D = (1) · (- 1) · (7) + 4 · (- 1) · 1 + (- 1) · 1 · (- 8) - (- 1) · (- 1) · 1 + 4 · 1 · 7 - 1 · (- 1) · (- 8)
D = - 7 - 4 + 8 - 1 + 28 - 8
D = 16
The system of linear equations have at least one solution. This system has only one solution any of the three equations is not a function of the other two. By algebraic handling we find that the unique solution of the system is: (x, y, z) = (- 2, 4, 3).
