Ryan went to lunch with his family. The cost of their meal was $130.
They left a tip of 18% on the $130 and paid the sales tax of 9% on the
bill. What was the total cost of the meal?

Answers

Answer:

$167.20

Step-by-step explanation:

0.18 x 130 = $32.4 (this is what they tipped)

the total now stands at $153.4 before tax

now to work out the tax you multiply the decimal of 9% by $153.4

0.09 x 153.4 = 13.8

the total cost of the meal is $167.20

The total cost of the bill will be equal to $167.20

What is the percentage?

The percentage is defined as representing any number with respect to 100. It is denoted by the sign %. The percentage stands for "out of 100." Imagine any measurement or object being divided into 100 equal bits.

Step-by-step explanation:

multiply in the brackets

5 × 5x = 25x, 5 × -2 = -10, 3 × x = 3x, 3 × -2 = -6

25x - 10 + 3x - 6

a path of width 2 meters runs around and outside a square plot of side 10 meters. then the area of the path is what square meters

I am 7th class ​

Answers

Answer:

area of the path = 96 m²

Step-by-step explanation:

See attached diagram.

The green square is the square plot of side 10 m.

The grey is the path of width 2 m running around the outside of the square.

The easiest way to calculate the area of the path is to work out the entire area of the path and square plot, then subtract the area of the green square from it.

Area of a square = (side length)²

Area of green square = 10² = 10 x 10 = 100 m²

We are told that the width of the path is 2 m, so the side length of the square incorporating the path AND the green square will be:

side length of green square + 2 + 2 = 10 + 2 + 2 = 14 m

Therefore, entire area = 14² = 14 x 14 = 196 m²

To find the area of the path only:

entire area - area of green square = 196 - 100 = 96 m²

So the area of the path is 96 m²

Answers

The period of the tangent function is given by:

b) 2pi

What is the period of a function?

It is the distance between the repetition of the function. If a function is defined on an interval and said to be periodic, the period is the length of the interval.

In this problem, the interval is [tex][-\pi, \pi][/tex], and after that the values will start repeating, hence the period is:

[tex]p = \pi - (-\pi) = 2\pi[/tex]

Thus option b is correct, as the period is of [tex]2\pi[/tex].

How do you solve isosceles and equilateral triangles

Answers

Short answer: X = 110* Y = 49*

To solve for x we have all the necessary numbers, because in an isosceles triangle two of the angles are equal.
So the angles are 35*, 35*, and x*
And since the interior angles of any given triangle will always equal 180*
Then we know that x = 180-70 (35+35) or X = 110*

Use the same method for the other triangle and you’ll get Y = 49*

Sorry if my math is off a little.
Hope this helps!

Answer:

x = 110°

Step-by-step explanation:

Triangle ABD is isosceles, with two 35° angles

angle x = (180-35-35)° = (180-70)° = 110°

The price of a new motorcycle is $4500, but the value of the motorcycle drops
by 11% each year. The function (t) = 4500 . 0.89 models this situation for v
dollars and tyears. What is a realistic domain for this situation?
.

Answers

t_>0. Option C. In the Test

A realistic domain for this situation is t = 0, 1, 2, 3, ... and consists of non-negative whole numbers representing the number of years after the motorcycle was purchased.

In the context of the situation, the domain represents the possible values for the number of years (t) for which the motorcycle's value is being calculated. Since the value of the motorcycle drops by 11% each year, it is reasonable to consider a domain that represents a finite number of years and includes only positive integers.

Typically, when modeling the depreciation of an asset like a motorcycle, it is reasonable to assume that the number of years (t) is a non-negative whole number (i.e., t = 0, 1, 2, 3, ...). The value at t = 0 represents the initial value of the motorcycle, and then each subsequent year represents the value after one more year of depreciation.

So, a realistic domain for this situation is t = 0, 1, 2, 3, ... and consists of non-negative whole numbers representing the number of years after the motorcycle was purchased.

A box of chocolates shaped like a regular hexagon is placed snugly inside of a rectangular box as shown in the figure.If the side length of the hexagon is 4 inches, what are the dimensions of the rectangular box? (30°-60°-90° )

Answers

A regular hexagon has 6 congruent sides.

The dimension of the rectangle is 8 inches by [tex]4\sqrt 3[/tex] inches

How to determine the length of the rectangle

Start by calculating the value of x using the following cosine ratio

[tex]\cos(60) = \frac{x}{4}[/tex]

Make x the subject

[tex]x = 4 * \cos(60)[/tex]

Evaluate cos(60)

[tex]x = 4 * 0.5[/tex]

[tex]x = 2[/tex]

So, the dimension of the rectangle is:

[tex]Length = 2x + 4[/tex]

[tex]Width = 2x\sqrt 3[/tex]

This gives

[tex]Length = 2 * 2 + 4[/tex]

[tex]Length = 8[/tex]

[tex]Width = 2 * 2\sqrt 3[/tex]

[tex]Width = 4\sqrt 3[/tex]

Hence, the dimension of the rectangle is 8 by [tex]4\sqrt 3[/tex]
