Answer:
2nd and 5th options
Step-by-step explanation:
the solution to a system of equations is at the point of intersection of the 2 lines.
If the lines are parallel then they never intersect and will have no solution.
The slopes m of parallel lines are equal.
The options with equal slopes , both - 2 are the
2nd and 5th options
Answer:
C
Step-by-step explanation:
1. 12+6 = 18 so that's the diameter of the big circle
2. next we take the square of 18 and multiply it by pi (324x3.14)
3. answer: 1017.36
SOLUTION:
= 3 / 4
= 75 / 100
= 0.75
Therefore, Robert came in first for 0.75 of his race.
Hope this helps. :)
Have a lovely day! <3
Answer:
Z-score = 1.5
Step-by-step explanation:
Z-score = (x-mean)/standard deviation
= (90-75)/10
= 1.5
Answer:
x = 14.4
Step-by-step explanation:
Similar means that the figures are proportional to each other. Because of this, we can form a problem. (the short side lengths) = (the long side lengths). Now we can solve this by cross-multiplying. If we multiply 9 · 8 we get 72, and 5 · x is 5x. 72 = 5x. Now divide both sides by 5. 72 ÷ 5 = 14.4. Therefore, x should be equal to 14.4. Does this make sense?
