Answer:
136
Step-by-step explanation:
7*5=35
35+35=70
1/2*6*4=12
12+12=24
6*7=42
70+42+24=136
sorry if it is wrong.
Upwards because a is one and therefore positive
Answer:
13% chance
Step-by-step explanation:
Area of backyard = length * width
A = 30 ft * 20 ft
A = 600 
Area of bathtub = π 
A = π *
A = 78.54 
Probability of arrow landing in tub can be found by dividing Area of the bathtub by the area of the backyard, and then multiplying by 100 for a percentage
Prob. = 78.54/600
Prob. = 0.13
Prob. = 0.13 * 100
Prob. = 13%
Answer: The third one
C.
Step-by-step explanation:
The equation of circle is:
(x-a)^2+(y-b)^2=r^2 where C(a, b) is the center.
In order to find r you have to find the distance between C(-2, 1) and let's say A(-4, 1)
The formula for distance is:

r = 2
The equation of circle is
(x+2)^2+(y-1)^2=4
