Answer:

$\sqrt {72} = 6\sqrt 2$

Step-by-step explanation:

Ashton estimates the square root of 72 in the following way:

√72=

2√36=

2×6=12

a) Explain why his reasoning is incorrect

This is incorrect because $\sqrt2 * 6$ is the correct answer but he has missed the square root term on 2.

$=\sqrt {2^2X2X3^2 }$

$=\sqrt {2^2} \sqrt 2 \sqrt {3^2 }$

$=2 X \sqrt 2 X 3$

$= \sqrt 2 X 6$

or can be written as:

$= 6\sqrt 2$

b) Estimate the square root of 72 to the nearest tenth without using your calculator. Show your work.

Find the factors of 72 we get $\sqrt {2X2X2X3X3 }$

Now, we will combine 2 terms if the are same so,

$=\sqrt {2^2X2X3^2 }$

$=\sqrt {2^2} \sqrt 2 \sqrt {3^2 }$

$=2 X \sqrt 2 X 3$

$= \sqrt 2 X 6$

$= 6\sqrt 2$

$\sqrt {72} = 6\sqrt 2$

What fraction is equivalent to 7.25?

Answers

The fraction equivalent to 7.25 is 7 and 25/100

The decimal .25 could be written as $(1)/(4)$ . So a fraction equivalent to 7.25 would be 7 $(1)/(4)$ .

If you want a mixed fraction, multiply 7 with the denominator and add it to the numerator. Then divide the new value by the denominator.
So 7 $*$ 4 = 28.
28 + 1 = 25.
$(25)/(4)$ .

The answer is $(25)/(4)$ .

Step-by-step explanation:

Rosie wrote this expression to describe the amount she paid for each yoga class. Which situation could be described by this expression? A. Rosie knows that each yoga class costs $30. She doesn't know how many classes she bought. B. Rosie knows that she paid $30 for one yoga class. She does not know the total amount she spent. C. Rosie knows that she paid a total of $30 for the yoga classes. She doesn't know how many classes she's gone to so far. D. Rosie knows that she paid a total of $30 for the yoga classes. She does not know how many classes she bought.

Answers

If Rosie is trying to figure out the amount that she needs to pay for her total yoga classes.

First, we need to establish what we know, and what we do not know.
We know that Rosie knows how many yoga classes she has.
We know that she knows how many yoga classes she bought.
She does not know how much each yoga class costs.

So, that cancels out A, B, and C because she doesn't know how much one yoga class costs.

It can only be D, because D tells us that she knows the total is $30, but not the amount each class costs.

Answer:

Rosie knows that she paid a total of $30 for the yoga classes. She does not know how many classes she bought.

CF is perpendicular to AE

Since those two triangles are congruent, all of their sides have to be equal as well as their angles. If CF was not equal to AE, then the two corresponding angles of the triangle which are also supplementary angles will not be congruent. The only pair of angle measures that is both supplementary and equal is 90 and 90. I hope this helps!
