Correct Answer: 60 \sqrt{5}

We are to find:

5 \sqrt{3} *4 \sqrt{15}

Multiplying and simplifying the radicals, we get:

20 \sqrt{45}  \\  \\ 
=20 \sqrt{9*5}  \\  \\ 
=20*3 \sqrt{5}  \\  \\ 
=60 \sqrt{5}

The hypotenuse of a 90-45-45 triangle is 20√2. What is the short leg and the long leg>
stepan [7]

Answer:

Both legs would be 20

Step-by-step explanation:
In the image below, it shows the relationship between the legs and the hypotenuse in every 45 45 90 triangle. If we know that the hypotenuse is 20, then the 2 legs are both 20.

I am slightly confused with the problem since they asked for the "short" leg and the "long" leg. Both legs should be the same length because a 45 45 90 triangle is isosceles, with the two legs being the same length.

The area is found by base x height

To find the missing height in the first one you divide 147 by 15 3/4 and get 9 1/3. 
To find the missing base in the second one you divide 140 5/8 by 11 1/4 and get 12 1/2.
To find the missing height in the third one you divide 151 3/16 by 10 1/4 and get 14 3/4.

Each calendar will sell for $5 each write an equatio to model the total income for selling calendars
Brrunno [24]
To answer the question above, I let x be the number of calendars sold. You may use any other letter as this is just for representation. The total income generated in selling calendars is calculated by multiplying the number of calendars with the price. That is,
                                   total income = 5x
If we let total income be y, our equation is further simplified into, 
                                            y = 5x

What is the answer for:
Blababa [14]

Answer:  6n + 3

Step-by-step explanation:

Since, Here  the smaller number = 2n - 1

Since, Numbers are consecutive.

Therefore, remaining numbers are 2n - 1 + 2 , 2n - 1 + 2 + 2

= 2n +1, 2n +3

Thus, the sum of these all numbers = 2n - 1 + 2n + 1 + 2n +3

= 6 n +3    ( By equating the like terms)
