Answer:
Adam's total cost: $9.20
Cindy's total cost: $9.20
Step-by-step explanation:
Since Adam and Cyndi's total bill costs $16, evenly splitting the cost means that each of them has to pay $8, not including the tip.
To find out the dollar value of their 15% tip, multiply $8 by 0.15:
$8 × 0.15 = $1.20.
Adam and Cindy will have to pay $8 (lunch cost) + $1.20 (tip) = $9.20 separately.
9362000 people had jobs in new york in 2002. if 41% of them worked in service positions, such as restaurants and dry cleaners, how many people were employed in the service industry in new york in 2002?
Answers
The number of people employed in the service industry in New York is 3,838,420.
How many people were employed in the service industry in 2002?
Percentage is a measure of frequency that is used to determine the fraction of an amount as a number out of hundred. The sign that represents percentage is %.
In order to determine the number of people employed in the service industry, multiply the percentage of the people who work in the service industry by the number of people who had jobs in 2002.
Number of people employed in the service industry = 41% x 9,362,000
0.41 x x 9,362,000 = 3,838,420

[tex]\sf 4\left(x+2\right)-2x=0[/tex]
Answers
Answer:
x = -4
Step-by-step explanation:
Step 1: Apply distributive property.
[tex](4)(x)+(4)(2)-2x=0[/tex] [tex]4x + 8 - 2x = 0[/tex]Step 2: Combine like terms.
[tex](4x-2x)+(8)=0[/tex] [tex]2x + 8 = 0[/tex]Step 3: Subtract 8 from both sides.
[tex]2x + 8 - 8 = 0 - 8[/tex] [tex]2x = -8[/tex]Step 4: Divide both sides by 2.
[tex]\frac{2x}{2} = \frac{-8}{2}[/tex] [tex]x = -4[/tex]Step 5: Check if solution is correct.
[tex]4(-4+2)-2(-4)=0[/tex] [tex](4)(-4)+(4)(2)+8=0[/tex] [tex]-16 + 8 + 8 = 0[/tex] [tex]-8 + 8 = 0[/tex] [tex]0 = 0[/tex]Therefore, x = -4.

The area of the parallelogram is 24 square miles find its base and height?
Answers
Answer:
Base-3 mi
Height-8 mi
Step-by-step explanation:
The area of a parallelogram is base*height.
Base*height=24
Now we just need to number that multiply to get 24. Those numbers can be 3 and 8 because 3*8=24.
The dimension of the parallelogram are 1 x 24, 2 x 12, 4 x 6, 8 x 3, and 24 x 1.
What is the area of the parallelogram?The opposite sides of the parallelogram are parallel and congruent. Let H be the height and W be the width of the parallelogram.
Then the area of the parallelogram will be
Area of the parallelogram = H × W square units
The area of the parallelogram is 24 square miles.
Then the dimension of the parallelogram is given as,
Area = 24
Area = 2 x 2 x 2 x 3
Area = 1 x 24, 2 x 12, 4 x 6, 8 x 3, 24, 1
The dimension of the parallelogram are 1 x 24, 2 x 12, 4 x 6, 8 x 3, and 24 x 1.

Step-by-step explanation:
First, let's turn these mixed fractions to regular fractions to make multiplying easier:

1 1/4 = 1/4 + 4/4 = 5/4
Then multiply:

The sum of three consecutive odd integers is 2,193. What are the integers? (show your work)
Answers
Answer: x = 729
Step-by-step explanation:
729+731+733 = 2193
x+(x+2)+(x+4) = 2193
3x +6 = 2193
Subtract 6 on both sides of the equal sign.
3x =2187
Divide 3 on both sides of equal sign so that you isolate the variable
x= 729
729, 731, 733
To get the three numbers plug in x to each equation in the first line .
x =729 729+2 = 731 729+4 =733
what slope intercept equation of the following line?
Answers
Answer: y=2x+7
Step-by-step explanation:
The og equation to get to the equation is y=mx+b. M=slope & B=y intercept
Lets first pick 2 points to find the slope (the formula is y2-y1/x2-x1). After using the formal, I got my slope as 2. Now I could say y=2x+b. Now to find the y intercept, the x point should be 0 because these are on going lines (you could tell by the infinite arrows) meaning there is no starting point. I got my y intercept as 7. Now, I know that y=2x+7.

Which equations are parallel to the line -3x-6y=30? Select all that apply.
A. 2x-y=15
B. 4y=20-2x
C. x=18-2y
D. y=-3x+1
E. 5x+10y=10
F. 6-2y=4x
Answers
Answer:
B and E
Step-by-step explanation:
The slope has to be 1/2 because the equation in the question is equal to 1/2 so only B and E are parallel
The equations of the line parallel to -3x-6y=30 are 4y=20-2x and 5x+10y=10. The correct options are B and E.
What is an equation of the line?An equation of the line is defined as a linear equation having a degree of one. The equation of the line contains two variables x and y. And the third parameter is the slope of the line which represents the elevation of the line.
The general form of the equation of the line is y = mx + c. Given that the equations are parallel to the line -3x-6y=30.
To check the line parallel to -3x-6y=30 find the slope of each line and if the slope is equal to the given equation of the line then both the lines will be parallel to each other.
The slope of the given equation of the line:-
-3x-6y=30
y = ( -1 / 2 )x + 5
Slope = -1 / 2
Check all the equations:-
A. 2x-y=15 or y = -2x + 15
B. 4y=20-2x or y = ( -1 / 2 )x + 5
E. 5x+10y=10 or y = ( -1 / 2)x + 1
Therefore, equations 4y=20-2x and 5x+10y=10 are parallel to the line -3x-6y=30.

∠A and \angle B∠B are vertical angles. If m\angle A=(7x-27)^{\circ}∠A=(7x−27) ∘ and m\angle B=(3x+29)^{\circ}∠B=(3x+29) ∘ , then find the value of x.
Answers
Answer:
x = 14
Step-by-step explanation:
Vertical angles are congruent , then
7x - 27 = 3x + 29 ( subtract 3x from both sides )
4x - 27 = 29 ( add 27 to both sides )
4x = 56 ( divide both sides by 4 )
x = 14

As the steps above show, the goal is to get both sides be the same identical expression. You should only work with one side to transform it into the other. In this case, the left side transforms while the right side stays fixed the entire time. The general rule is that you should convert the more complicated expression into a simpler form.
We use other previously established or proven trig identities to work through the steps. For example, I used the pythagorean identity [tex]\sin^2(\theta)+\cos^2(\theta) = 1[/tex] in the second to last step. I broke the steps into three parts to hopefully make it more manageable.
