Graphs are attached.

__

Equations are in slope-intercept form, so it is convenient to graph them by identifying the y-intercept, then finding another point or two based on the slope.

Of course, the y-intercept is the constant in the equation. This is where the line crosses the y-axis. The slope is the coefficient of x, and represents "rise" over "run", the number of units the line goes up for every unit to the right.

Dominic is a server at a restaurant. Each dish at the restaurant costs $8. A sales tax of 8% is charged. The total bill amount includes the sales tax of the meal.

Dominic earns tips left by customers. The amount of money tipped can be represented by a percentage of the total bill.

Order the tip amounts from least to greatest tip, in dollars.

5 dishes
17.5% tip

6 dishes
14% tip

7 dishes
11% tip

4 dishes
20% tip

Answers

Answer:

In this order is least to greatest:

1. 4 dishes-20% tip

2. 6 dishes -14% tip

3. 7 dishes-11% tip

4. 5 dishes-17.5% tip

Order the tip amounts from least to greatest tip will be $6.65, $6.91, $7.25, and $7.56.

What is the percentage?

The amount of any product is given as though it was a proportion of a hundred. The ratio can be expressed as a quarter of 100. The phrase % translates for one hundred percent. It is symbolized by the character '%'.

The percentage is given as,

Percentage (P) = [Final value - Initial value] / Initial value x 100

Dominic is a server at a restaurant. Each dish at the restaurant costs $8. A sales tax of 8% is charged. The total bill amount includes the sales tax of the meal.

The amount of tip for all the orders, then we have

A. 5 dishes and 17.5% tip, then the tip cost is given as,

⇒ ($8 x 5) x (1.08) x (0.175)

⇒ $7.56

B. 6 dishes and 14% tip, then the tip cost is given as,

⇒ ($8 x 6) x (1.08) x (0.14)

⇒ $7.26

C. 7 dishes and 11% tip, then the tip cost is given as,

⇒ ($8 x 7) x (1.08) x (0.11)

⇒ $6.65

D. 4 dishes and 20% tip, then the tip cost is given as,

⇒ ($8 x 4) x (1.08) x (0.20)

⇒ $6.91

Order the tip amounts from least to greatest tip will be $6.65, $6.91, $7.25, and $7.56.

The height of the parallelogram is 6/7 units and base of the parallelogram is one third of the height. Find the area of the parallelogram.
147/36 sq. units
36/147 sq. units
6/21 sq. units
6/63 sq. units

Answers

Answer:

Area of the parallelogram:

A = a * h

where a is the base and h is the height;

91 = a * h

a = 2 h + 1

( 2 h + 1 ) * h = 91

2 h² + h - 91 = 0

h 1/2 = ( - 1 +/- √(1+728)) / 4 = ( - 1 +/- 27) / 4

h = 6.5 ( another solution is negative )

a = 2 * 6.5 + 1 = 13 + 1 = 14

The base is 14 units and the height 6.5 units long.

The smallest number that is a common multiple to the denominator of two or more fractions is called the least common denominator.

Now, given fractions are 4/7 and 7/10, note that 70 is the smallest number that is a common multiple of 7 and 10, therefore, multiply the numerator and the denominator of the first fraction by 10 and the second fraction by 7.

Therefore, 4/7=40/70 and 7/10=49/70

Find the value of x.

Answer:

I want to say the answer is D

Step-by-step explanation:

The angle is supplementary because if you remove that line it becomes a 180 degree angle so you would have to subtract 57 - 180 to find the value of x.

The last one is correct.

Because:

A supplimentary angle its a 180° angle. meaning that if you subtract 57 from 180 you will get 123 and 123+57=180°.
