Answer:
<h2>43 1/2</h2>
Step-by-step explanation:
The formula to find the area of a triangle is multiplying base times height divided by 2.
So we have 3+3+3 (which is the base) times height. Finally we have: 9 x 11, which is 99 and now we divide it by 2. So 99/2 = 49 1/2.
Now we subtract the missing rectangle, which we can find by multiplying 3 by 2, which is 6.
So now subtract 6 from 49 1/2, and you'll get 43 1/2.
What is the question you only put the number?
Answer:
D
Step-by-step explanation:
The formula for calculating circumference (C) are
C = 2πr ( r is the radius ) → D
or
C = πd ( d is the diameter )
Answer:
103.5
Step-by-step explanation:
c is correct
X+y+z=22
(x+y+z+t)/4=8
subsitute
x+y+z=22
(22+t)/4=8
multiplly by 4
22+t=32
subtract 22
t=10
the fourth number is 10
