Answer: 12 cm^2
Step-by-step explanation:
BC ==> Base of triangle
Divide the triangle in two parts:
BC/2=BC'
6/2=BC'
BC'=3
Distance formula: a^2+b^2=c^2
c^2-a^2=b^2
5^2-3^2=b^2
25-9=b^2
b^2=16
b=4 ==> height of triangle
Area of triangle=A. b=base. h=height
A=1/2 * b * h=
A=1/2 * 6 * 4
A=1/2 * 24
A=12 cm^2

change each mixed number to an improper fraction
33 1/2 = (2*33 +1)/2 67/2
1 1/4 = (4*1+1)/4 = 5/4
67/2 divided by 5/4

67/2 * 4/5
268/10
26 8/10
26 4/5 miles per gallon
Answer:
A
Step-by-step explanation:
∠ABC is formed by 2 tangents to the circle and is measured as
∠ABC =
(m arc ADC - m arc AC ), that is
(y - 119) = 61 → A
<span>So we need to find the average speed of the bus that travels 20 km in 30 minutes. Average speed is defined as: Average speed=distance travelled/time taken or: v=s/t. We know s=20 km and t=30 minutes=0.5h. So after we input our numbers in the equation, we get: v=20km/0.5h=40km/h. So the correct answer is C) 40km/h.</span>
