Hi!
Let's separate this shape into three sections to make it easier to find the area. (see image)
Let's start with the green shape.
The base of the green shape is 20. The height is 6.
20 x 6 = 120
Now the blue shape.
The base of the blue shape is 20, the height is (9 + 6) 15.
20 x 15 = 300
Now the red shape.
The base of the red shape is (20 - 10) 10, the height is 5.
10 x 5 = 50
Add all of the areas together.
120 + 300 + 50 = 470
The answer is
470Hope this helps! :)
Answer:
20
Step-by-step explanation:
2x + 10 = 50
-10 -10
2x = 40
x = 20
Answer:
The 5th day must be 90
Step-by-step explanation:
The first 4 days averaged out to 80
You can find their total just by multiplying by 4. That won't tell you the exact values, but it will tell you their total when you add the 4 of them together.
80*4 = 320
Now you need to add another day into the mix. Call it x
320 + x
Now there are 5 days, not 4, and the new total is 82.
(320 + x) / 5 = 82 Multiply both sides by 5
5*(320 + x) / 5 = 82 *5
320 + x = 410 Subtract 320
-320 -320
x = 90
