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.

if manny the martian's shadow is 17.5 ft. in length and the shadow of a yard stick sitting perpendicular to the ground is 7.5 ft., what is manny's height

Answers

Answer:

Here the ratio of length of the shadow to the height of the object (in this case a yardstick) is 15:36. The ratio of shadow to the height of tree will also be the same. the shadow of tree is 25 feet long. So the height of tree will be (25*36)/15, that is 60 feet.

you are hiking along a trail that in 13½ miles long.you plan to rest every 2¼miles.how many rest stops will you make?

Answers

Answer:

6 stops

Step-by-step explanation:

well if you stop every 2 1/4 miles for 13 1/2....13 1/2 divided by 2 1/4 is 6. So they'll stop 6 times.

The number of rest stops before finishing the trail is 5 rest stops.

Given,

You are hiking along a trail that is 13½ miles long.

you plan to rest every 2¼miles.

We need to find how many rest stops will you make.

How do distribute equally a given value?

We divide the given value by the total number of items we want to distribute.

Example:

In 35 minutes how many 5 minutes?

= 35/5

= 7

We have,

Trail distance = 13 1/2 miles = 27/2 miles

Distance travelled before every each = 2 1/4 miles = 9/4 miles

The number of 4/9 miles in 27/2 miles.

= 27/2 / 9/4

= 27/2 x 4/9

= 27x4 / 2 x 9

= 3 x 2

= 6 times.

This means on the 6th time you have already finished the trail so,

You have rested 5 times before finishing the trail.

Thus the number of rest stops before finishing the trail is 5 rest stops.

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

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

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

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

350 = 1, 2, 5, 10, 7, 14, 25, 35, 50, 70, 175, 350

Highest common factor of 275 and 350 is 25.

The HCF of 275 and 350 is given by the equation A = 25

What is HCF and LCM?

The Greatest Common Divisor GCF or the Highest Common Factor HCF is the highest number that divides exactly into two or more numbers. It is also expressed as GCF or HCF

Least Common Multiple (LCM) is a method to find the smallest common multiple between any two or more numbers. A common multiple is a number which is a multiple of two or more numbers

Product of HCF x LCM = product of two numbers

Given data ,

Let the HCF of the two numbers be represented as A

Now , the equation will be

Let the first number be p = 275

The factors of 275 = 1 , 5 , 11 , 25 , 55 and 275

Let the second number be q = 350

The factors of 350 = 1, 2, 5, 7, 10, 14, 25, 35, 50, 70, 175 and 350

So , the highest common factor of 275 and 350 is 25

Therefore , the value of A is 25

Hence , the HCF is 25
