A class is planning a trip to the local City Museum of Art. The class needs 3 trucks and 1 car to transport all 22 people on the trip.

Generally, To solve this problem, we can set up a system of equations using the information given. Let C be the number of cars needed and T be the number of trucks needed.

The first equation will represent the number of people that can be transported in the cars: 4C + 6T = 22

The second equation will represent the number of drivers: C + T = 4

Now we can solve this system of equations using elimination or substitution.

Using elimination, we can multiply the first equation by 2 and the second equation by 4 to get: 8C + 12T = 44 4C + 4T = 16

Then we can subtract the second equation from the first equation to get: 4C + 8T = 28

Then we can divide both sides by 4 to get: C + 2T = 7

Then we can substitute this value for C in the second equation to get: 7 - 2T = 4 T = 1.5

Since T represents the number of trucks, which must be a whole number, this solution is not possible.

Using substitution, we can solve for C in the second equation and substitute it into the first equation: C = 4 - T 4(4 - T) + 6T = 22 16 - 4T + 6T = 22 2T = 6 T = 3

Substituting this value for T into the second equation, we get: C = 4 - 3 C = 1

Answer:

360 in commission.

Step-by-step explanation:

If you received a 4% commission on the TVs you sold, and you sold $9,000 worth of TVs, then you would have received 4/100 * $9,000 = $<<4/100*9000=360>>360 in commission.

Answer:

P= RS. 9000

R=7.6%

T= 9 months

Simple Interest (SI}=?

By using formula,

SI= PTR/100

= 9000* 7.6* 9/ 100* 12

= 615600/1200

Answer:

39 inches

Step-by-step explanation:

All of the sides are the same length because all of the angles are equal

21 - x = 2x - 3  Set two sides equal to each other and solve for x.  Add x to both sides

21 = 3x - 3  Add 3 to both sides

24 = 3x  Divide both sides by 3

x = 8

Substitute in 8 for x to find the value of a side

2x - 3

2(8) - 3

16 - 3

13

Each side length is 13

3 x 13 = 39

Answer:

To calculate the interest rate for your account, you will need to use the formula for simple interest:

Interest = Principal x Rate x Time

In this case, the principal is the amount of money you deposited, or $600. The time is the number of months the money was in the account, or 18 months. And the interest is the amount of money you earned, or $31.50.

Plugging these values into the formula, we get:

$31.50 = $600 x Rate x 18

To solve for the rate, we can divide both sides of the equation by $600 and 18:

Rate = $31.50 / ($600 x 18)

Simplifying this expression gives us:

Rate = 0.01625

So, the interest rate for your account is approximately 1.625%.

The length of side BC is approximately 10.928.

What is the right triangle?

In a right triangle, the side opposite the right angle is called the hypotenuse. In triangle ABC, side AC is the hypotenuse, and sides AB and BC are the other two sides.

To find the length of side BC, we can use the Pythagorean theorem, which states that in a right triangle, the square of the length of the hypotenuse is equal to the sum of the squares of the other two sides.

We can use the given information to write the Pythagorean theorem in the form:

AC^2 = AB^2 + BC^2

Substituting the given lengths, we get:

13² = 5² + BC²

Solving for BC, we get:

BC = √(13² - 5²)

= √(144 - 25)

= √(119)

= approximately 10.928

Therefore, the length of side BC is approximately 10.928.

Answer:

5.75

Next you would divide 11.5/2 because a triangle is half of a square.11.5/2 is 5.75

The value of the tangent of angle 37° is 3/4. Then the height of the cell tower will be 24.5 meters.

Trigonometric functions examine the interaction between the dimensions and angles of a triangular form.

A specialist gazes toward the highest point of a cell tower. The specialist stands 30 meters from the focal point of the pinnacle with a view of 37° from the level. The designer's eyes are 2 meters over the ground.

Let 'h' be the height of the tower. Then we have

tan 37° = (h - 2) / 30

Simplify the equation, then we have

tan 37° = (h - 2) / 30

3/4 = (h - 2) / 30

4h - 8 = 90

4h = 98

h = 24.5 meters

The level of the cell pinnacle will be 24.5 meters.

The minimum score Sam needs to get on his final exam to get a "C" in the course is 82.

What is a probability?

A random event's occurrence is the subject of this area of mathematics. The range of the value is 0 to 1. Mathematics has incorporated probability to forecast the likelihood of various events.

Given that, Sam's test scores are 62, 71, and 65.

The total score in three test is (62 + 71 + 65) = 198

Assume that, he scored x in the final test.

Total score of Sam is 198 + x.

He needs to score 70% means he needs to score 70 out of 100.

According to question,

(198 + x)/ 400 ≥ 70/100

Multiply both sides by 100:

(198 + x)/ 4 ≥ 70

Multiply both sides by 4

198 + x ≥ 280

x ≥ 280 - 198

What is limits?

Limits are very interesting concepts in mathematics which are veryuseful when we are dealing with numbers like infinity or numbers where some functions are not defined

Concepts of limits give us brief understanding that why these things are not defined

Solution;

We are asked to calculate a limit

By limits laws we can apply limit to both numerator and denominator respectively

Numerator = lim x--->2 2x-2

= just put 2 in place of x we will get 4 - 2 = 2 ans

Denominator = 2f(3x) - x

put limit as x = 2 in this we get

Step-by-step explanation:

The correct values for A, B and C are given as follows:

The table shows the ratios of black to white keys on pianos of various sizes, and these ratios are constant, meaning that the following proportional relationship is established:

A/13 = 18/B = 45/65 = 72/C

Then the value of A can be obtained as follows:

A/13 = 45/65

Applying cross multiplication, we have that:

65A = 13 x 45

A = 13 x 45/65

A = 9.

The value of B can be obtained as follows:

18/B = 45/65

Applying cross multiplication, we have that:

45B = 18 x 65

B = 18 x 65/45

B = 26.

Finally, the value of C can be obtained as follows:

72/C = 45/65

Applying cross multiplication, we have that:

Comparing two amounts of the same units and determining the ratio tells how much of one quantity is in the other.

when evaluating the relationship between two quantities or numbers. In general, x: y, which can be interpreted as "x is to y," is used to denote a ratio between two quantities.

Here we have

15 Cookies need 80g Oats

=> Amount of Oats for 1 cookie = 80g/15 gms

So the amount Oats for 36 Cookies = 80g/5 × 36 = 192 grams

15 Cookies need 340 grams of Maple syrup

=> Amount of Maple syrup for 1 cookie = 340/15 gram

So the amount of Maple syrup for 36 cookies = (340/15)×36 = 816 grams

By the above calculations,

For 36 Cookies we need 192 grams of Oats and 816 grams of Maple syrup

The Ratio of Oats to Maple syrup = 192 gram: 816 gram

Equation used to represent the relation between the number of pages written to the number of hours used with constant of proportionality is

x = 4y.

As given in the question,

Let us consider number of pages write by Bill be 'x'

And number of hours represented by 'y'

Number of hours used by Bill to write 4 pages = 1 hour

Number of pages written by Bill in 1 hour = 4

Given :

Number of pages is proportional to the number of hours

⇒ x ∝ y

⇒ x = ky

Where 'k' is the constant of proportionality.

When x = 4 , y = 1

substitute the value in the equation,

4 = k(1)

⇒ k = 4

Now the required equation with the constant of proportionality k = 4 is:

x = 4y

Therefore, the required equation to represent the relation between number of pages written to the number of hours used with constant of proportionality is equal to x =4y.

Answer:

m∠QRS = 30°

m∠SRT = 75°

Step-by-step explanation:

Now,

The sum of m∠QRS and m∠SRT is equal to m∠QRT which is 105°

So,

m∠QRS + m∠SRT = m∠QRT

(6x)° + (14x + 5)° = (105)°

6x + 14x + 5 = 105

20x + 105 - 5

20x = 100

x = 100/20

x = 5

Thus, The value of x is 5°

Now,

m∠QRS = (6x)° = 6 × 5 = 30°

m∠SRT = (14x + 5)° = 14(5) + 5 = 70 + 5 = 75°

Answer:

x = 90 , y = 43

Step-by-step explanation:

Since AB and AC are congruent , then Δ ABC is isosceles with base angles congruent , that is

∠ ABD = ∠ ACD = 47°

AD is the perpendicular bisector of BC , so

∠ ADB = x = 90

the sum of the 3 angles in Δ ABD = 180° , then

y = 180° - (90 + 47) = 180 - 137 = 43
