Answer:
231.7 cm^2
Step-by-step explanation:
We can find the area by adding the area of the rectangle to the area of the 2 triangles.
The rectangle is
7+7+7 by 9
21 by 9
A = length * width
A = 21*9
A = 189
The triangles are identical so we find the area of one of them and multiply by 2
The base is 7 and the height is 6.1
A = 1/2 b*h
but since we have 2 of them
2A = 2*1/2 b*h
2A = b*h
2A = (7* 6.1)
= 42.7
Add the rectangles area to the area of the two triangles
189 + 42.7
231.7 cm^2
Answer:
It is not arithmetic sequence
Step-by-step explanation:
If you take any number in the sequence then subtract it by the previous one, and the result is always the same or constant then it is an arithmetic sequence.

Answer:

Step-by-step explanation:
Given
Molly: 50 out of 200
Joel: x out of 280
Required
Find x
Start by representing the giving parameters as ration
Molly= 50 : 200
Joel = x : 280
From the question, the ratios are equivalent. So,

Convert to fractions

Solve for x
