Answer:

Step-by-step explanation:

The length of side AC can be found by counting the squares between AC: 8.

The length of side BC can be found using the Pythagorean Theorem. B is 3 units to the right of C and 4 units above C. Thus:

|BC| = √(3² + 4²) = √25 = 5.

|AC| has the same length: 5.

Thus, the perimeter of this triangle is 5 + 5 + 8, or 18.

Complete question

To find $\sqrt{5}$ , Beau found $2^2 = 4$ and $3^2 = 9$ . He said that since 5 is between 4 and 9, $\sqrt{5}$ , is between 2 and 3. Beau thinks a good estimate for $\sqrt{5}$ , is $\frac{2 + 3}{2} = 2.5$ Is his estimate high or low? How do you know?

Answer:

The estimation is high because 5 is very close to 4 so $\sqrt{5}$ will also be very close to $\sqrt{4}$ which is lower than the estimate

In order to get a good estimate

The first step is to choose a number between 2 and 3 let say 2.8 , 2,85 , 2.9 and the square them

i.e

$2.1^2 = 4.41$

$2.2^2 = 4.84$

$2.3^2 = 5.29$

From here we can see that $\sqrt{5}$ lies between 2.2 and 2.3 but is closer to 2.2

So a good estimate for $\sqrt{5}$ is 2.2

Translate the phrase into an algebraic expression.

adell [148]

Answer:

8 + $\frac{5}{w}$

Step-by-step explanation:

From the phrase, the answer is smaller(less) by 8 when compared(equal (=)) to quotient of 5 and w ...

So:

Answer - 8 = quotient of 5 and w

Here, quotient is the whole number from a division. The division here is $\frac{5}{w}$

Therefore,

Answer - 8 = $\frac{5}{w}$

Answer = 8 + $\frac{5}{w}$

Hence the phrase into algebraic expression is 8 + $\frac{5}{w}$
