David received a 20% tip on a bill of $86.40. how much was his tip?

choli [55]

To find the tip of the bill. You will need to find how much of $86.40 is 20%. In this question, they're asking how much is the tip, not how much will the final price be.

When you multiply a percentage you move the decimal point 2 times to the left: 20. → .20

You would multiply $86.40 by .20

When you solve it 86.40 × .20 = 17.28

$17.28 is 20% of $86.40

$17.28 will be the amount he got for his tip.

Find the radius of a circle in which an inscribed square has a side of 8 inches.

Semenov [28]

Answer:

$4\sqrt{2} =5.66$

Step-by-step explanation:

The square is in the circle, so the diameter is the diagonal line of the square. This divides the square into two right triangles.

Two sides of the right triangle equal 8. This qualifies it as a special right triangle. This triangle has two sides that = x (in this case 8) and the hypotenuse is $x\sqrt{2}$ .

Substitute 8 in for x.

$8\sqrt{2}$ is the diameter, so we divide in half to get the radius = $4\sqrt{2}$

A group of 5 people paid for general admission to the museum. Some of the people also bought movie tickets. The whole group spen

sashaice [31]

Answer:

5 k + x m = 108 is the needed equation.

k : Cost of 1 general admission ticket

x : Number of movie tickets purchased.

m : cost of 1 movie ticket.

Step-by-step explanation:

The number of people who visited the museum = 5

The total amount spent on general admission and movie tickets = $108

x : the number of movie tickets purchased

Let us assume the cost of each ticket = $ m

So, the cost of x tickets = x ( cost of 1 ticket) = x ( $m) = m x

Also, the general admission amount for 1 person = $ k

⇒ General admission amount for 5 people = 5 x ( $k) = 5 k

So, according to the question:

The general admission + Amount + cost of x movie tickets = $ 108

$ 5 k + x m = 108

So, here: 5 k + x m = 108

k: Cost of 1 general admission ticket

x: Number of movie tickets purchased.

m : cost p=of 1 movie ticket.

Hence, the needed equation is 5 k + x m = 108.
