Answer: its 11

Step-by-step explanation:

DE is similar to BF and BF is half the line of BC so half of 22 is 11

Answer:

11

Step-by-step explanation:

Another way you can think is as

\frac{AD}{AB}  =  \frac{AD}{2AD}  =  \frac{1}{2}

Given D & E are mid points of AB & AC

So, DE must be parallel to BC

By the property of similar triangles

ADE ~ ABC

\frac{DE}{BC}  =  \frac{1}{2}  \\  \frac{DE}{22}  =  \frac{1}{2 }  \\ DE =  \frac{22}{2}  = 11

Hope it helps too ;))

Elodia [21]

Answer:

addition and multiplication are the inverse of subtraction and division, respectively.

The inverse of a function can be viewed as reflecting the original function over the line y = x. In simple words, the inverse function is obtained by swapping the (x, y) of the original function to (y, x).

We use the symbol f − 1 to denote an inverse function. For example, if f (x) and g (x) are inverses of each other, then we can symbolically represent this statement as:

g(x) = f − 1(x) or f(x) = g−1(x)

One thing to note about the inverse function is that the inverse of a function is not the same as its reciprocal, i.e., f – 1 (x) ≠ 1/ f(x). This article will discuss how to find the inverse of a function.

Since not all functions have an inverse, it is therefore important to check whether a function has an inverse before embarking on determining its inverse.

During a certain day, a worker made 81 parts. He usually does 45 parts per day. What was the percent by which he increased the n
Lana71 [14]

Answer:

The answer is 80%.

Step-by-step explanation:

During a certain day, a worker made 81 parts.

He usually does 45 parts per day.

Number of extra parts made = 81-45=36

The percent by which he increased the number of parts he usually makes can be given as = \frac{36}{45}\times100 = 80%

Therefore, on that day, the percent increased by 80%.
