Answer:5 people were in each car.
Step-by-step explanation:
Let x represent the number of people that travelled in each car.
The total number of people in the Bailey family that made the trip to the drive-in movie theater was 42.
Seven cars filled and 7 more people traveled in a truck. This means that
7x + 7 = 42
Subtracting 7 from the left hand side and the right hand side of the equation. It becomes
7x + 7 - 7 = 42 - 7
7x = 35
Dividing the left hand side and the right hand side of the equation by 7, it becomes
7x/7 = 35/7
x = 5
Answer:
12y-24
thats what the answer is to your problem
21+-3 so 18 to 24 is the answer
Answer:
66.91 km^2
Step-by-step explanation:
This answer will be long:
Interior angles of hexagon sum to (4)(180) = 720 each is 120 degrees
each side is 24/6 = 4 km
area of hexagon = 12 * 1/2 2 * (2 tan60) =<u> 41.5692 km ^2 </u>
L triangle 5 = hypot leg1 = 4 leg2 = 3 area = 1/2 * 3 * 4 =<u> 6 km^2</u>
TOP triangle is 4 = hypot leg1 = 3.464 leg2 = 2
area = 1/2 * 3.464 * 2 = <u>3.464 km^2</u>
R triangle two legs = 4 area = 1/2 * 4 x 4 =<u> 8 km^2 </u>
BOTTOM triangle two sides = 4 use sin rule sin40/4 = sin 100/x
third side = 4/sin 40 * sin 100 = 6.1284 km
semi perimter = ( 4 + 4 + 6.1284) / 2 = 7.0641 km
Use Herron's rule for area =
sqrt ( 7.0641 (7.0641-4)(7.0641-4)(7.0641-6.1284) ) =<u> 7.878 km^2 </u>
<u> add all of the areas to get 66.91 km^2 (IF I made no math errors!) </u>
It should be 12cm because
h=height
a=area
b=base
h=a/b we have base 15cm and height 8cm
8cm=a/15cm
8cm*15cm=a
120cm^2=a
we then use the area to find the height with base 10
h=a/b
h=120cm^2/10cm
h=12cm
