Answer:
<h2>1525.7 square meters, approximately.</h2>
Step-by-step explanation:
Notice that the radius is 28 meters, and the angle of the orange sector is 137°. However, the angle of the blue sector is:
360° - 137° = 223°
The area of a circular sector is
Replacing given values, we have
Therefore, the right answer is the second choice.
The number 1934 can be written as:
1,000 + 900 +30 +4
so the value of the 3 is 30, of the 9 is 900 and of the 1 is 1000.
900 is indeed 10 times 30, so
"<span>the value of the 9 in the hundreds place ten times the value of the 3 in the tens place</span>"
Answer: true
Answer:
put the equations in tiger math
Step-by-step explanation:
The least common is 3 x 3=9
1 step. Let ABC be a triangle with vertices
Define segments BD and CE as medians of triangle ABC.
2 step. Write linear equation for medians BD and CE:
- median BD passes through points B and the midpoint D of AC, then The equation of BD is
- median CE passes through the points C and the midpoint E of AB, then The equation of CE is
3 step. Solve the system of equations:
4 step. Write an equation for AO, where O is the point of intersection BD and CE.
5 step. Write an expression for the midpoint of BC, point F:
6 step. Check that coordinates of point F satisfy the equation of AO (then f lies on AO and AO is the third median, that means that all three medians intersect in one point).
Simplify it and get 1=1. This means that point F lies on AO.
