Answer:
m = 170
Step-by-step explanation:
The angles are supplementary so they add to 180 degrees
70 + m-60 = 180
Combine like terms
10 + m = 180
Subtract 10 from each side
10-10 +m = 180-10
m = 170
Answer:
(-2, 5)
Step-by-step explanation:
The form you're trying to match is the vertex form of the equation of a parabola:
y = a(x -h)^2 +k . . . . . . . vertex (h, k)
You have ...
y = -4(x +2)^2 +5
Comparing forms, you see that a=-4, h=-2, k=5.
Then the vertex (h, k) is (-2, 5).
When the metronome was created out of a piece of solid wood, the minimum amount of solid wood that was used from the pyramid will be C. 540 centimeters cubed.
<h3>How to calculate the pyramid?</h3>
From the information given, the metronome ticks at adjustable intervals to help keep time when playing music.
In rhis case, when the metronome was created out of a piece of solid wood, the minimum amount of solid wood that was used from the pyramid will be:
= 20 × 9 × ✓9
= 20 × 9 × 3
= 540

Answer:
The answer to your question is: P(A) = 0.47
Step-by-step explanation:
Data
7 red flowers
3 white flowers
5 yellow flowers
Probability that he select a red one
Formula
P(A) = Number of favorable cases of A / total number of outcomes
Number of favorable cases = 7
Total number of outcomes = 7 + 3 + 5 = 15
Substitution
P(A) = 7 / 15
P(A) = 0.47
