Answer:
20 yards
Step-by-step explanation:
The area of a square is calculated by multiplying its height by its base. Because they are the same in a square, the area of a square is obtained by squaring one of its sides. Let's call the sides 'x'. Then we can express the area of the garden as x^2=400.
From here we simply need to square root both sides which gives us:
x=20
Therefore the length of one side of the garden is 20 yards.
Hope this helped!
Answer:
A
Step-by-step explanation:
Since the triangles are similar then the ratios of corresponding sides are equal, that is
=
, substitute values
=
← cross- multiply
2.7TU = 3.3 × 1.8 ← divide both sides by 2.7
TU =
→ A
Answer:
the gcd of 50 100 and 120 is 20
Step-by-step explanation:
Answer:
1. 3.14
Step-by-step explanation:
If we have

That just equals

For example, consider function

The inverse of that function is




So

If we compose the function, f(x) into f^-1(x).
We get

That proof of that.
1. Here x=f^-1(3.14)and f(3.14) cancel out so the answer is 3.14
2. We first find f(-7) which is -12,
We then find f(-12)= 5 so the answer here is 5.
1-31= -30.
Taking an absolute value makes any value positive, so -30 becomes 30.
The absolute value of 1-31 is 30.
