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?
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.

Answer:
[tex] \frac{11}{20} [/tex]
Step-by-step explanation:
*0.45 can be put over 1. (All decimals can)
Multiply the numerator and denominator by 100, then simplify:
[tex] \frac{0.45 \times 100}{1 \times 100} = \frac{45 \div 5}{100 \div 5} = \frac{9}{20} [/tex]
Multiply both fractions:
[tex] \frac{9}{20} \times \frac{11}{9} = \frac{99}{180} [/tex]
Simplify:

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
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

A. -2:1
B. X-3:3x-2
С. 3x x
D. (4x-12): (12x-8)
E. X-1 : x - 2
Answer:
B and D
Step-by-step explanation:
(2x-6):(6x-4)
you can divide everything by 2
2x÷2=x, -6÷2=-3
6x÷2=3x, -4÷2=-2
so it's B X-3:3x-2
(2x-6):(6x-4)
multiply everything by 2
2x × 2 = 2x, -6 × 2 = -12
6x × 2 = 12x, -4 × 2 = -8
so it's D (4x-12): (12x-8)
Answer:
x-3:3x-2 and (4x-12): (12x-8)
Step-by-step explanation:
Divide both sides by 2, then multiply both sides by 2

Answer:
[tex]y=\frac{3}{4} x+6[/tex]
Step-by-step explanation:
Slope intercept form is y=mx+b.
Subtract 6x from both sides.
-8y=-6x-48
Then, simplify by dividing both sides by -8 and simplifying the fractions.
You end up with:

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?
.
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.

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:

Since the centre of dilatation is the origin then multiply the coordinates of B by the scale factor.
B (4, 8 ) → B' (4 × [tex]\frac{1}{4}[/tex] , 8 × [tex]\frac{1}{4}[/tex] ) → B' (1, 2 )
