Answer:
Reflection, Triangle B is a reflection of A
Step-by-step explanation:
Reflection <em>is when we flip a figure over.
</em>
Translation <em>is when we slide a figure in any direction.
</em>
Rotation <em>is when we rotate a figure a certain degree around a point.
</em>
Dilation <em>is when we enlarge or reduce a figure.</em>

Answer with Step-by-step explanation:
We are given that a sample space
S={a,b,c,d,e}
P(a)=0.1
P(b)=0.1
P(c)=0.2
P(d)=0.4
P(e)=0.2
a.A={a,b,c}
P(A)=P(a)+P(b)+P(c)
P(A)=0.1+0.1+0.2=0.4
b.B={c,d,e}
P(B)=P(c)+P(d)+P(e)=0.2+0.4+0.2=0.8
c.A'=Sample space-A={a,b,c,d,e}-{a,b,c}={d,e}
P(A')=P(d)+P(e)=0.4+0.2=0.6
d.
={a,b,c,d,e}
=P(a)+P(b)+P(c)+P(d)+P(e)=0.1+0.1+0.2+0.4+0.2=1
e.
={c}

Answer:
133 1/3 km/hour
Step-by-step explanation:
Average speed is computed as ...
average speed = (total distance)/(total time)
= (80 km +120 km +200 km)/(2/3 + 1 + 1 1/3 hour) = 400 km/(3 hour)
= 133 1/3 km/hour
Answer:
49
Step-by-step explanation:
Product of GCD and LCM = Product of the 2 numbers
Product of GCD and LCM = 7 × 140 = 980
One number is 20 so let the other number be N
20×N=7×140
20N=980
2N=98
N=49
so the other number is 49
Answer:
A statement that is true about the angle measures of the pieces is that the angle measure of each piece is 72°. This is because there are 360° in a full circle, and if each piece is equal, that means that each piece is a fifth of that. Therefore, the angle measure is 360/5= 72°
