The Washington family had dinner at a restaurant and the bill was $85.00. They gave their server a $13.60 tip. What percent of the cost of the meal did they leave as a tip?

Answer:

-3 = N

Step-by-step explanation:

2-2N=3N+17

Add 2N to each side

2-2N+2N=3N+2N+17

2 = 5N +17

Subtract 17 from each side

2-17 = 5N+17-17

-15 = 5N

Divide each side by 5

-15/5 = 5N/5

-3 = N

Answer:

N= -3

Step-by-step explanation:

First, bring 3N on to the left side by subtracting 3N with 2N

2-2N-3N=17

Then, move 2 to the right side by subtracting 17 and 2: -2N-3N= 17-2

Solving the like terms gives us -5N= 15

N= 15/-5

N= -3

Answer:

The angels are 60 degrees and 120 degrees

Step-by-step explanation:

The sum of two supplementary angels equal 180 degrees.

So, lets look at the ratio: 6:3

We then add 6 and 3 together which gives us 9.

Then you put it in this equation:

9x = 180

x= 20

- You are adding the two numbers and dividing the sum by 180 because the answer will tell us how much 1 would equal.

- In this case, we multiply 20 by 6 = 120 degrees

- Then we multiply 20 by 3 = 60 degrees.

(We can check our answer by: 120 + 60 = 180 degrees) :)

Answer:

D

Step-by-step explanation:

Mathematically, for us to have a right triangle, Pythagoras’ theorem must be obeyed

From the theorem, the square of the hypotenuse (longest side) equals the sum of the squares of the two other sides

Let us take a look at the given set of numbers:

2 square is not same as 1 squared + 1 squared

9 squared is not equal to 3 squares + 5 squared

7 squared is not equal to 4 squared + 3 squared

But;

root 2 squared equals 1 squared plus 1 squared and that is our answer

Answer:

x = 4

Step-by-step explanation:

By intersecting secants theorem:

[tex]10(10 + 2x) = 9(2x + 3 + 9) \\ \\ 100 + 20x = 18x + 108 \\ \\ 20x - 18x = 108 - 100 \\ \\ 2x = 8 \\ \\ x = \frac{8}{2} \\ \\ x = 4[/tex]

Answer:

433.5

Step-by-step explanation:

The volume of the cone with a radius of 6ft and a height of 10ft is approximately 301.4 cubic feet.

A cone is simply a 3-dimensional geometric shape with a flat base and a curved surface pointed towards the top.

The volume of a cone is expressed as;

V = (1/3)πr²h

Where r is the radius of the base, h is the height of the cone and π is constant pi ( π = 3.14 ).

From the diagram:

Slant height l = 10 ft

Radius r = 6 ft

Height h =?

Volume V =?

First, we determine the height of the cone using Pythagoras theorem:

h² = 10² - 6²

h² = 100 - 36

h² = 64

h = √64

h = 8

Plug the values into the above formula and solve for the volume:

V = (1/3)πr²h

V = (1/3) × 3.14 × 6² × 8

V = (1/3) × 3.14 × 36 × 8

V = 301.4 ft³

Therefore, the volume is approximately 301.4 cubic feet.

*see attachment for the diagram of the wall

Answer:

6 cans

Step-by-step explanation:

First, let's calculate the area of the wall to be painted = area of a rectangle

Area of the rectangle = length*width

From the diagram,

Length = 13 ft

Width = 10 ft

Area = 13*10 = 130 ft²

Given that 1 can of paint covers 25 ft²,

Number of can of paints that will cover 130 ft² = 130/25 = 5.2

This means we will need more than 5 cans. So Joan will need to get roughly 6 cams of blackboard paint.

Answer:

(31, 2); Substitution.

Step-by-step explanation:

x - 3y = 25

Use SUBSTITUTION by setting everything in the above equation equal to x...

x = 3y + 25

2(3y +25) + y = 64

6y + 50 + y = 64

7y + 50 (-50) = 64 (-50)

7y = 14

y = 2

Then, substitute y = 2 into the original equation.

x - 3(2) = 25

x - 6 = 25

x = 31

(x, y) = (31, 2)

Answer:

the answer is

Step-by-step explanation:

There are more students in biology than students in geometry.

The following statements does not support the given venn diagram:

There are 55 students taking geometry and biology.

There are more students in biology than students in geometry.

What are Venn diagrams?

The components of a set or group are schematically represented by a Venn diagram. It is a diagram that depicts every conceivable logical connection between a finite collection of sets or groups. It is also known as set diagram.

In a Venn diagram, sets of various elements are represented by many overlapping shapes (often circles). It seeks to give a pictorial representation of the components, emphasizing their similarities and differences.

Solution:

                                   17₊ 22 ₊8 = 47

The result of the addition operation is not equal to the number of        students, hence it does not support to the statement.

                                    17 ₊ 22 = 39

The result of the addition operation is equal to the number of        students, hence it supports the statement.

                                     17 ₊ 8 = 25 and 8 ₊ 22 = 30

                                            where, 25 < 30

Here, we can observe that students are less in biology and more in geometry, hence the result does not support the statement.

                                     22 ₊ 8 = 30

                                       30 > 17

Here, we can observe that students are more in geometry than students taking only biology, hence the result supports the statement.

So the following statements does not support the venn diagram given:

There are 55 students taking geometry and biology.

There are more students in biology than students in geometry.
