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 $\sqrt{2}$

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 9 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 9 purses in her collection.
