Hello. Good?
Formula for calculating two overlapping sets:
A + B - both + not (A or B) = Total
20 (french) + 20 (german) - 10(both) + Not = 50
40 - 10 + not = 50
30 + not = 50
not = 50 - 30
not = 20
Answer: 20 students do not speak french or german.
Thanks, I hope I have helped.
Answer:
Option C and option D
Step-by-step explanation:
we have that

This is the equation of a vertical parabola open upward
The vertex is a minimum
Convert the equation into vertex form
Complete the square




----> equation of the parabola in vertex form
The vertex is the point (2,1)
therefore
when the bird is 2 feet away from the first fence post, it reaches its minimum height of 1 foot
As the scale drawing and the actual car are similar .
so,
height of bumper in drawing
height of bumper in actual car=height of the window in drawing/height of the window in actual car
6 in./16*12 in.=¾ in./height of the window in actual car
height of the window in actual car=¾*16*12/6 in.

Answer:
14 = 8 + 2d
Step-by-step explanation:
Odometer is a device that is equipped in the vehicles to count the distance traveled by the vehicle.
It has been given in the question that,
Distance between beach and her friend's house = d miles.
Distance between Brenna's house and her friend's house = 8 miles
Total distance traveled by Brenna = 14 miles.
Starting from the Brenna's house, we will add each distance traveled till the end of her journey and will make it equal to the 14 miles.
So,
Total distance = Distance between Brenna's house and her friend's house + Distance between her friend's house and beach + Distance between beach and her friend's house
Thus, we can now put the values as,
14 = 8 + d + d
We will get the final equation as
14 = 8 + 2d
