The answer is 20% of the 1000 people, as 100%-80%+20%. 1000 times 0.2 equals 200 people that knew the name.

The square ABCD has side length 20 cm,
bogdanovich [222]

Answer:

AE=22.4

Step-by-step explanation:

BE is 1/2 of BC

BC is 20 cm                 All sides of a square are equal

BE = 1/2 BC                  Property of a midpoint.

BE = 10

Now just use Pythagorus

AB^2 + BE^2 = AE^2

AE^2 = 20^2 + 10^2   Perform the sqrs

AE^2 = 400 + 100      Add the terms

AE^2 = 500                Take the square root of both sides

√AE^2 = √500

AE = 22.36

AE ≈ 22.4

Find the indicated length. find LM
Roman55 [17]

The overall length is given as 22.

The line is split into 2 parts X and 3X.

So we have X + 3X = 22

Add X and #X to get 4X:

4X = 22

Divide both sides by 4 to get X:

X = 22 /4

X = 5.5

Now we know what X is so now replace x with 5.5 and solve for LM:

LM = 3X = 3*5.5 = 16.5

You have been asked to find the inverse of f(x) = 3+ V2 - 1. What would your first step be?
Aleonysh [2.5K]

Answer:

Add 1 to both sides of the equation.

Subtract 3 from both sides of the equation.

Step-by-step explanation:

The inverse of a function refers to that function that tends to undo another function.

If we intend to find the inverse of the function, f(x) = 3+ V2 - 1, we have to first add 1 to both sides of the equation and subsequently subtract 3 from both sides of the equation before taking the square root of both sides to obtain the inverse function.
