Answer:
420
Step-by-step explanation:
Simple addition! I double checked!
10 yellow cards over 30 = 10/30
second selection : 9 yellow cards over 29 = 9/29
10/30 * 9/29 = 1/3 * 9 /29 = 3/29 = 0.1034 = 10.34%

Answer:
See below ~
Step-by-step explanation:
<u>Circle 1</u>
- Circumference = 2πr = 2 x 3.14 x 2.5 = 5 x 3.14 = 15.7 m
- Area = πr² = 3.14 x (2.5)² = 3.14 x 6.25 = 19.625 m²
<u>Circle 2</u>
- Area = πr² = 3.14 x 1² = 3.14 mm²
- Circumference = 2πr = 2 x 3.14 x 1 = 6.28 mm
Answer:
m<C = 66°
Step-by-step explanation:
Perpendicular bisector, AB divides angle CAD into two equal parts. Therefore:
(5x + 9)° = (7x + 3)°
Solve for x
5x + 9 = 7x + 3
Collect like terms
5x - 7x = -9 + 3
-2x = -6
Divide both sides by -2
x = 3
✔️m<C + m<CBA + m<BAC = 180° (sum of triangle)
m<C + 90° + (7x + 3)° = 180 (substitution)
Plug in the value of x and solve
m<C + 90 + 7(3) + 3 = 180
m<C + 90 + 21 + 3 = 180
m<C + 114 = 180
m<C = 180 - 114 (Subtraction property of equality)
m<C = 66°
