• Ok so first for the rectangle:
Use the formula: b•h
50 • 20 = 1000 ft2
• Next, the triangle:
Formula: b•h/2
Add the 10 and 50, which is 60.
60 • 20 = 1200
1200/2 = 600 ft2
• For the circle:
Formula: π • r^2
The radius is 10ft
3.14 • 10^2
3.14 • 100 = 314 (Whole circle)
Since we need half of the circle, we divide by 2 to split them.
314/2 = 157 ft2
• Now add all together:
1000 + 600 + 157 = 1757 ft2
I don’t know if you meant b^2 and c^2 or b x 2 and c x 2 so I’ll do both.
If it’s meant to be multiplied by 2, then you do 9^2 + (40)2 =c2
81 + 80 = c2
161 = c2
/2
80.5 = c
However I do doubt it’s that. This means it’s likely meant to be squared instead. In which case, use the following answer.
9^2 + 40^2 =c^2
1681 = c^2
Then square root both sides to get just c (which i assume is what you’re trying to find?)
Square root of 1681 = 41
So your answer would be 41.
Answer:
y=18.2 x=5.6
Step-by-step explanation:
sin 73 = y/19
19 sin 73 = y
cos 73 = x/19
19 cos 73 = x
There are several information's already given in the question. Based on those information's, the answer can be easily deduced.
The equation given in the question is
x = 0.8x + 72
x - 0.8x = 72
0.2x = 72
x = 360
Now
Number of people that became
member of the site = (80/100) * 360
= 288 people
From the above deduction, it can concluded that the correct option among all the options that are given in the question is 288.
