It’s a prediction so basically an estimate of how much students he thought were going to be there. An actual number is the real total.
Answer:
should be 30
Step-by-step explanation:
triangles have 180°
if x is 30
2x is 60
the other angle is 90
add those all together and you get 180°
Answer:
=-4
Step-by-step explanation:
Answer: D. n + q = 20
5n + 25q = 300
Step-by-step explanation:
Let n represent the number of nickels that you have.
Let q represent the number of quarters that you have.
Suppose you have 20 coins. It means that
n + q = 20
The total value of the coins is $3. The value of a quarter is $0.25 and the value if a nickel is $0.05. Therefore, the equation would be
0.05n + 0.25q = 3
Multiplying both sides of the equation by 100, it becomes
5n + 25q = 300
The correct option is
D. n + q = 20
5n + 25q = 300

Steps:
1. Draw a line connecting the point to the center of the rectangle
2. Then construct a perpendicular bisector to the line drawn in step 1
3. Place the compass on the midpoint of the line, adjust its length to reach the end point, and draw an arc across the circle
4. Where the arc crosses the circle will be the tangent points. So connect the endpoint to the tangent point
