2√72 + 5√242 what is the answer for this question please can u tell me the right answer​
Radda [10]

Answer:

67\sqrt{2}

Step-by-step explanation:

Assuming you require to simplify the expression.

Using the rule of radicals

\sqrt{a} × \sqrt{b} ⇔ \sqrt{ab}

Simplifying the radicals

\sqrt{72} = \sqrt{36(2)} = \sqrt{36} × \sqrt{2} = 6\sqrt{2}

\sqrt{242} = \sqrt{121(2)} = \sqrt{121} × \sqrt{2} = 11\sqrt{2}

Then

2\sqrt{72} + 5\sqrt{242}

= 2(6\sqrt{2} ) + 5(11\sqrt{2} )

= 12\sqrt{2} + 55\sqrt{2}

= 67\sqrt{2}

Sophie [7]

Number of ounces left is 1120

Step-by-step explanation:

  • Step 1: Find number of ounces left after each day.

Given total soup prepared each day = 15 gallons

Amount served each day = 1/4 of 15 = 15/4 gallons

Amount left after each day = 15 - 15/4 = 60 - 15/4 = 35/4 gallons

  • Step 2: Convert gallons into ounces. 1 gallon = 128 ounces

35/4 gallons = 35/4 × 128 = 1120 ounces

Cierra has three more than 1/2 as many purses as Asia defined a variable and write an expression to represent the number of purs
Ray Of Light [21]

Answer:

The equation representing the number of purses Ceirra has is c=3+\frac{1}{2}\times a.

Ceirra has <u>9</u> purses in her collection.

Step-by-step explanation:

Given,

Cierra has three more than 1/2 as many purses as Asia.

Solution,

Let the number of purses Cierra has be 'c'.

And also the number of purses Asia has be 'a'.

Now according to question, Cierra has 3 more than 1/2  purses as Asia has.

Framing in equation form, we get;

c=3+\frac{1}{2}\times a

Hence The equation representing the number of purses Ceirra has is c=3+\frac{1}{2}\times a.

Now we solve the equation;

Since Asia has 12 purses.

So we substitute the value of 'a', and get;

c=3+\frac{1}{2}\times12=3+6=9

Hence Ceirra has <u>9</u> purses in her collection.
