Answer:
528 cm²
Step-by-step explanation:
First I would calculate the area of the side rectangles:
20 x 9 = 180 cm²
There are two identical rectangles on both sides so i would x2
180 x 2 = 360 cm²
The area of the middle rectangle:
6 x 20 = 120 cm²
The area of the triangles:
Area of a triangle = (Base x Height)/2
8 x 6 = 48
48 ÷ 2 = 24
There are two identical triangles on the bottom and the top so x2
24 x 2 = 48
Now add all the values up:
360 + 120 + 48 = 528 cm²
I hope this helps!
Answer:
The ladder reach a height 8.485 ft.
Step-by-step explanation:
The ladder with the building made right angle triangle
The length of the ladder is the hypotenuse 12 ft.
The angle between the ladder and the building is 45°
The height of the ladder reach is the vertical side of the Δ
∴ h = 12 cos 45° = 6√2 = 8.485 ft.
( f + g ) (x) = –2x + 6
( f – g ) (x) = 8x – 2
( f × g ) (x) = –15x2 + 2x + 8

Answer:
2 sweatshirts per student
Step-by-step explanation:
I'm not sure whether or not I understood this problem correctly, but I tried my best. Try to make your questions more clear in the future.
($35 per ticket * 16 students) + ($19 per sweatshirt * X sweatshirts sold) = $960
$560 from the sweatshirt + 19X = 960
19X = 960 - 560 = $400
X = 21 sweatshirt sold overall
Number of sweatshirt sold per student = 21/19 = 1.105 ---> 2 per student
Answer:
10n-13+3y
Step-by-step explanation:
The only way to simplify is add like terms. This is an expression so no answer can be displayed.
n+9n=10 n
-10-3=-13
and 3y is by itself.
