Zoe goes out to lunch. The bill

DanielleElmas [232]

Answer:

$60

Step-by-step explanation:

To find how much Zoe paid before the sales tax and tip, we first need to consider the amount she paid in sales tax and tips.

Sales tax + Tips = $18.60

Let x = original price

Sales tax = 11% * original price

Sales tax = 0.11 * x

x= 0.11x

Tips = 20% * original price

Tips = 0.20 * x

x = 0.2x

Now that we have a value for both the sales tax and tips, we can then proceed to find the original price by:

0.11x + 0.2x = 18.60

0.31x = 18.60

Now we need to divide both sides by 0.31 to find x.

x = 60

Zoe's dinner before the sales tax and tips was $60.

8h+(-6.3d)-15+4d-3.3h

Drupady [299]

Answer:

Not exactly sure if you are asking to simplify, but that is all I can do with the information you have given.

Here is the simplified version:

−2.3d + 4.7h − 15

Step-by-step explanation:

Combine Like Terms:

=8h+−6.3d+−15+4d+−3.3h

= (−6.3d+4d) + (8h+−3.3h) + (−15)

= −2.3d+ 4.7h − 15

A person casts a shadow that aligns with a shadow of a tree. the person is 5.5 feet tall and casts a shadow 8.25 feet long. the

SOVA2 [1]

An equation that can be used to determine the tree's height is 22.5/8.25 = x/5.5.

The height of this tree is equal to 15 feet.

The distance of this person from the tree is equal to 14.25 feet.

<h3>What are the properties of similar triangles?</h3>

In Geometry, two (2) triangles are similar when the ratio of their corresponding sides are equal in magnitude and their corresponding angles are congruent.

Additionally, two (2) geometric figures are considered to be congruent only when their corresponding side lengths are congruent and the magnitude of their angles are congruent.

Now, we can write an equation that can be used to determine the tree's height. Since the ratio of the corresponding sides of similar triangles are equal in magnitude, we have the following mathematical expression (equation):

22.5/8.25 = x/5.5

Where:

x represents the height of the tree.

22.5/8.25 = x/5.5

Cross-multiplying, we have:

8.25x = 22.5 × 5.5

8.25x = 123.75

x = 123.75/8.25

x = 15 feet.

<h3>How far is the person standing from the tree?</h3>

The distance of this person from the tree can be calculated as follows;

Distance = Length of tree's shadow - Length of person's shadow

Distance = 22.5 - 8.25

Distance = 14.25 feet.
