Alex’s lunch at a restaurant costs $13.00, without tax. He leaves the waiter a tip of 17% of the cost of the lunch, without tax.

motikmotik

Answer:

$15.21

Step-by-step explanation:

The total cost will be the cost of the meal plus the tip.

The tip is 17% of the meal's price. Multiply 13 by 0.17, and you will have $2.21 as the tip.

$13 + $2.21 = $15.21

Explain how combining like radicals is similar to combining like terms.

pickupchik [31]

Answer:

Just like combining like terms with the same variables, you combine like

radicals with the same number under the radical signs.

Step-by-step explanation:

Example:

3x + 2x

= 5x {combined like terms}

3√2 + 2√2

= 5√2 {combined like radicals}

Find the area of the following shape. Show all work

Pavel [41]

Best way to solve this is by using

$\sqrt{s(s - a)(s - b)(s - c)}$

$where \: s = \frac{a + b + c}{2}$

s=(12+8+17)/2

=18.5

using the formulae

area =43.5

Rob peeled 125 oranges in 5 hours. At that rate, how many oranges<br> would he peel in 12 minutes?

marin [14]

Answer:

$\boxed {\tt 5 \ oranges}$

Step-by-step explanation:

Let's set up a proportion.

$\frac{oranges}{minutes} =\frac{oranges}{minutes}$

He can peel 125 oranges in 5 hours. First, let's find the minutes in 5 hours.

There are 60 minutes in 1 hour, so multiply 60 and 5 (60*5=300). There are 300 minutes in 5 hours.

$\frac{125 \ oranges}{300 \ minutes}=\frac{oranges}{minutes}$

We don't know how many oranges he can peel in 12 minutes. So we say he can peel x oranges in 12 minutes.

$\frac{125 \ oranges}{300 \ minutes}=\frac{x \ oranges}{12 \ minutes}$

$\frac{125 \ }{300 \ }=\frac{x \ }{12 }$

Solve for x by isolating it. x is being divided by 12. The inverse of division is multiplication. Multiply both sides of the proportion by 12.

$12*\frac{125 \ }{300 \ }=\frac{x \ }{12 \ }*12$

$12*\frac{125 \ }{300 \ }=x$

$12*0.416666667=x$

$5=x$

Rob can peel 5 oranges in 12 minutes.
