Answer:

$11.50

Step-by-step explanation:

To find the 15% tip, let’s break it up into simple pieces.

We know that 15 is 10 + 5.

First, find 10% of 10, which is simply 1. (You move the decimal point over one time)

5% of 10 is half of what 10% of ten is. Therefore, 5% of ten is 0.5.

Now, we add all the numbers together (10+1+0.5) and you get 11.5.

If you jut want the tip, don’t add ten to your equation.

How many 4 card hands that contain exactly 3 aces and 1 queen can be chosen from a 52 card deck?

sesenic [268]

There are 16 possible hands.

Choosing 3 aces from 4 possible is expressed by:
$_4C_3=\frac{4!}{3!1!} = 4$

Choosing 1 queen from 4 possible is expressed by:
$_4C_1=\frac{4!}{1!3!}=4$

This gives us 4*4 = 16 possible hands.

Answer:

x = 7, arc DE = 198°

Step-by-step explanation:

Inscribed angles from the same arc are congruent.

∠ DCE and ∠ DWE are inscribed angles from the same arc DE , thus

12x + 15 = 3x + 78 ( subtract 3x from both sides )

9x + 15 = 78 ( subtract 15 from both sides )

9x = 63 ( divide both sides by 9 )

x = 7

Thus

∠ DCE = 12x + 15 = 12(7) + 15 = 84 + 15 = 99°

The inscribed angle DCE is half the measure of its intercepted arc, thus

arc DE = 2 × 99° = 198°

Using a 10' long piece of strut as a straightedge, you are trying to determine the outside diameter of a grain storage silo. You

Vesna [10]

The radius of the silo is the distance from its center to the outside wall

The radius of the silo is 7 3/8" or 7 3/8 inches

<h3>How to determine the radius?</h3>

From the question, we have the following parameters:

Length of strut = 10'
Outside diameter of silo = 14 3/4"

The radius is then calculated as:

Radius = 0.5 * Diameter

This gives

Radius = 0.5 * 14 3/4"

Evaluate the product

Radius = 7 3/8"

Hence, the radius of the silo is 7 3/8" or 7 3/8 inches
