The correct answer is 10,1 Have a great day! :)
Answer:
<em>33.75 red counters</em>
Step-by-step explanation:
Given the ratio of the red counters to blue counters as 5:4. The total ratio will be 5 + 4 = 9
If there are 27 blue counters in the bag, the total amount of counters there will be gotten using the expression;
4/9 * x = 27
x is the total counter in the bag.
4x/9 = 27
4x = 9*27
x = (9*27)/4
x = 60.75
The amount of red counters there will be
red counters = Total - blue counter
red counter = 60.75 - 27
<em>red counter = 33.75 red counters</em>
We turn -5,12 into polar coordinates. It's a Pythagorean Triple so
r = 13 Ф=arctan(-12/5) + 180° ( in the second quadrant )
so -5 = 13 cos Ф, 12 = 13 sin Ф
12 sin x - 5 cos x = 6.5
13 sinФ sin x + 13 cos Ф cos x = 6.5
13 cos(x - Ф) = 6.5
cos(x - Ф) = 1/2
cos(x - Ф) = cos 60°
x - Ф = ± 60° + 360° k integer k
x = Ф ± 60° + 360° k
x = 180° + arctan(-12/5) ± 60° + 360° k
That's the exact answer;
x ≈ 180° - 67.38° ± 60° + 360° k
x ≈ 122.62° ± 60° + 360° k
x ≈ { 62.62°, 182.62°} + 360° k, integer k
Answer:
3n + 75
Step-by-step explanation:
Multiply n by 3 = 3n
Multiply 25 by 3 = 75
Answer:
y = 2x + 7
The m in the equation is the slope and the b is always the y-intercept.
