Answer:

12

Step-by-step explanation:

Using the rule of radicals

\sqrt{a} × \sqrt{b} ⇔ \sqrt{ab} and \sqrt{a} × \sqrt{a} = a

Given

\sqrt{8} × \sqrt{18}

Simplifying each radical

\sqrt{8} = \sqrt{4(2)} = \sqrt{4} × \sqrt{2} = 2\sqrt{2}

\sqrt{18} = \sqrt{9(2)} = \sqrt{9} × \sqrt{2} = 3\sqrt{2}

Thus

\sqrt{8} × \sqrt{18}

= 2\sqrt{2} × 3\sqrt{2}

= 2 × 3 × \sqrt{2} × \sqrt{2}

= 6 × 2

= 12

Keisha bought cups of coffee and bagels for the people in her office. Each bagel cost $2 and each cup of coffee cost $1.50. Keis
-Dominant- [34]

Answer:

The number of bagels is <u>11</u> and the cups of coffee is <u>12</u>.

Step-by-step explanation:

Given:

Keisha bought cups of coffee and bagels for the people in her office. Each bagel cost $2 and each cup of coffee cost $1.50.

Keisha spent a total of $40 to buy 23 items.

Now, to find the number of cups of bagels and coffee.

As given in question:

Let x represent the number of bagels.

And y represent the number of cups of coffee.

So, the total number of items:

x+y=23

x=23-y    ......(1)

Now, the total money spent on items:

2x+1.50y=40

Substituting the value of x from equation (1):

2(23-y)+1.50y=40

46-2y+1.50y=40

46-0.50y=40

<em>Subtracting both sides by 46 we get:</em>

-0.50y=-6

<em>Dividing both sides by -0.50 we get:</em>

y=12.

<em>The number of cups of coffee = 12.</em>

Now, to get the number of bagel we substitute the value of y in equation (1):

x=23-y

x=23-12

x=11.

<em>The number of bagels = 11.</em>

Therefore, the number of bagels is 11 and the cups of coffee is 12.
