Answer:

total earning is  $64.80

Step-by-step explanation:

Price of one work = $18.00

Payment  by owner = 1/4 of $18.00

                                 = 18/4

                                  = $4.50

Earning by tip =  20% of $18.00 =  20/100 x18 = 3.60

Total earning from one work   =   $4.50+$3.60

                                                = $ 8.10

Earning from 8 tips =  8x8.10

                                = $64.80

Used PEMDAS:

P Parentheses first

E Exponents (ie Powers and Square Roots, etc.)

MD Multiplication and Division (left-to-right)

AS Addition and Subtraction (left-to-right)

First Power, next Addition

Answer: A.

Step-by-step explanation:

2, 5, 10, 17, 26

First, check the difference between each term:

2 → 5 = +3

5 → 10 = +5

10 → 17 = +7

17 → 26 = +9

Since the difference (d) is not the same, this is not an arithmetic sequence.

Now, check the second tier {3, 5, 7, 9}

3 → 5 = 2

5 → 7 = 2

7 → 9 = 2

The difference (d) of the second tier is the same, so it is an exponential sequence.

--> the only option that is an exponential sequence is option A.

Answer:

Short-response question = 20.

Step-by-step explanation:

Let x be number of short response questions and y be the number of essay questions.

We have been given that there are 22 questions that are worth 100 points in total. Each short-response question is worth 4 points, and each essay question is worth 10 points. Using our given information we can form a system of equations as:

[tex]x+y=22...(1)[/tex]  

[tex]4x+10y=100...(2)[/tex]

Now we will solve our system of equations using substitution method.

From equation 1 we will get,

[tex]y=22-x[/tex]

Upon substituting [tex]y=22-x[/tex] in equation 2 we will get,

[tex]4x+10(22-x)=100[/tex]

[tex]4x+220-10x=100[/tex]

[tex]4x-10x=100-220[/tex]

[tex]-6x=-120[/tex]

[tex]x=\frac{-120}{-6}[/tex]    

[tex]x=20[/tex]  

Therefore, there are 20 short-response questions on the exam.

x/4*4 = 10*4

x = 40

Answer:The Answer of this probelm is D 40.

Step-by-step explanation:

x/4 - 7=3

First you need to add 7 to both sides

x/4 - 7+7=3+7

x/4 = 10

second you need to multiply by 4 on each side

x/4*4 = 10*4

Once you finish this should be your final answer right here x = 40

Answer:

Money  club have after the show is  $358 .

Step-by-step explanation:

As given

The art club at a school raised $248 at a car wash.

They spent $206 to set up an art show, and raised $316 at the art show by selling artwork the members had made.

Than

Money club have after the show =  school raised money at a car wash +  Raised money at the art show  -  spent money to set up an art show.

Money club have after the show =  248 +  316 - 206

Money club have after the show =  564 - 206

Money club have after the show =  $358

Therefore  money  club have after the show is  $358 .

Answer:

It is 358.

Step-by-step explanation:

The club started with $248, and then spent $206.

248−206=42

The club had $42, left after they spent for the art show.

Then, they raised another $316, at the show.

42 + 316 = 358

Answer: 358

First question:

By definition of sine and cosine, we have

[tex]\sin30^\circ=\dfrac h{\sqrt5}\implies h=\dfrac{\sqrt5}2[/tex]

[tex]\cos30^\circ=\dfrac g{\sqrt5}\implies g=\dfrac{\sqrt{15}}2[/tex]

Second question:

By definition of tangent, we have

[tex]\tan60^\circ=\dfrac{5\sqrt2}x\implies x=\dfrac{5\sqrt2}{\sqrt3}=\dfrac{5\sqrt6}3[/tex]

Then by Pythagoras' theorem,

[tex](5\sqrt2)^2+x^2=y^2\implies y=\sqrt{(5\sqrt2)^2+\left(\dfrac{5\sqrt6}3\right)^2}=\sqrt{50+\dfrac{50}3}=\sqrt{\dfrac{200}3}=\dfrac{10\sqrt6}3[/tex]

So firstly, we need to find how much the entire trip will cost. To do this, add the product of 16 and 35 (since tickets are 35 per student, and there are 16 students) with 960:

[tex](35*16)+960\\560+960\\\\\$ 1520[/tex]

The total cost of the trip is $1520. Next, we know that the sweatshirts will be making a profit of $19 per article sold so divide 1520 by 19:

[tex]1520\div 19=80[/tex]

The students need to sell 80 sweatshirts total to get enough money for the trip. Now, to know how many sweatshirts each student needs to sell individually, divide 80 by 16 (since there are 16 students):

[tex]80\div 16=5[/tex]

In short, each student must sell 5 sweatshirts to pay for the entire trip.

The height of Cone Mountain, given the trail length and the radius, would be C. 2,520 feet

How to find the height ?

To find the height of Cone Mountain, we can use the properties of a right circular cone. The key relationship we'll use is the Pythagorean theorem :

[tex]l^2 = r^2 + h^2[/tex]

The slant height (l) is the length of the trail, which is 3,150 feet.

The radius (r) is 1,890 feet.

Pythagorean theorem:

[tex](3,150)^2 = (1,890)^2 + h^29,922,500 = 3,572,100 + h^2[/tex]

Make h the subject:

[tex]h^2 = 9,922,500 - 3,572,100\\h^2 = 6,350,400[/tex]

Take the square root of both sides to find h:

h = √(6,350,400)

h = 2,520 feet

Answer:

(D)68

Step-by-step explanation:

If 1 litre =4.23 cups

and 1 cup = 8 ounces

Therefore: 1 litre = 4.23 X 8 Ounces = 33.84 Ounces

2 litres = 2 x 33.84 Ounces

           =67.68 Ounces

           =68 Ounces (To the nearest whole number)

The number of ounces in 2 liters will be 68 ounces. Thus, the correct option is D.

Given that:

1 liter = 4.23 cups

1 cup = 8 ounces

Unit modification is the process of converting the measurement of a given amount between various units, often by multiplicative constants that alter the value of the calculated quantity without altering its impacts.

The number of cups in 2 liters is calculated as,

⇒ 2 x 4.23

⇒ 8.46 cups

The number of ounces in 8.46 cups is calculated as,

⇒ 8.46 x 8

⇒ 67.68 or 68 ounces

Thus, the correct option is D.

The least common multiple of 7 and 3 is 21, so both the football and volleyball teams will have games on the same day again in 21 days.

The question requires us to determine when the football and volleyball teams will have games on the same day again. Since the football team plays every 7 days and the volleyball team plays every 3 days, we are looking for the least common multiple (LCM) of 7 and 3, which represents the number of days until both teams will have games on the same day again.

To find the LCM of 7 and 3, we can list the multiples of each number until we find a common multiple:

Multiples of 7: 7, 14, 21, 28, ...

Multiples of 3: 3, 6, 9, 12, 15, 18, 21, ...

The first common multiple we encounter is 21. Therefore, both teams will have games on the same day again in 21 days.

Let the Distance traveled by the tourist by walking be : D miles

Given : Tourist walks at a rate of 4 Miles per Hour

[tex]\mathsf{\implies Tourist\;travels\;D\;Miles\;in : \frac{D}{4}\;Hours}[/tex]

Given : The Total Distance of Mountain Path = 31 Miles

Distance traveled by the tourist by hiring a Taxi is : (31 - D) Miles

Given : The Taxi travels at a constant speed of 50 miles per hour

[tex]\mathsf{\implies Tourist\;travels\;(31 - D)\;Miles\;in : (\frac{31 - D}{50})\;Hours}[/tex]

Given : The Tourist reaches the destination 2 Hours after he started

Time taken by Walking + Time Taken by travelling in Taxi = 2 Hours

[tex]\mathsf{\implies \frac{D}{4} + \frac{31 - D}{50} = 2}[/tex]

[tex]\mathsf{\implies \frac{D}{2} + \frac{31 - D}{25} = 4}[/tex]

[tex]\mathsf{\implies (\frac{25D + 2(31 - D)}{50}) = 4}[/tex]

[tex]\mathsf{\implies (\frac{25D + 62 - 2D}{50}) = 4}[/tex]

[tex]\mathsf{\implies ({23D + 62}) = 200}[/tex]

[tex]\mathsf{\implies 23D = 200 - 62}[/tex]

[tex]\mathsf{\implies 23D = 138}[/tex]

[tex]\mathsf{\implies D = 6}[/tex]

⇒ Distance traveled by the tourist by walking = 6 Miles

⇒ Distance traveled by the tourist by hiring a taxi = (31 - 6) = 25 Miles

⇒ The Distance for which tourist has to pay for cab driver is 25 Miles

The distance traveled by taxi = 25 miles

2*10 = 20

Total is 80 Euros charge

10% booking fee

so 10% of 80 is 8 (Add this onto the total bill) = 88

3% of 88 is (well 1% is 0.88 3% is 0.88 * 3 = 2.64)

Answer:

x = 5

Step-by-step explanation:

in ΔABC , AB = BC , hence triangle is isosceles, thus

∠A = ∠C = 73° ( base angles are equal )

the sum of the 3 angles in a triangle = 180°

subtract the sum of the base angles from 180 for ∠B

∠B = 180° - (73 + 73)° = 34°

⇒ 6x + 4 = 34 ( subtract 4 from both sides )

6x = 30 ( divide both sides by 6 )

x = 5
