Answer:

Step-by-step explanation:

Given the simultaneous equation

3x+4y=15. Equation 1

3x-y=30. Equation 2

Using elimination method

Sutract equation 2 from 1

Then, will have

3x-3x+4y--y=15-50. -×-=+

4y+y=-15

5y=-15

Divide Both sides by 5

y=-15/5

y=-3

From equation 2

3x-y=30

3x--3=30

3x+3=30

3x=30-3

3x=27

Divide both side by 3

x=27/3

x=9

Then, x=9 and y=-3

Answer:

x=7 y=-9

Step-by-step explanation:

Use a system of equations to solve.

3x-y=30 changes to y=-30+3x

This can then be substituted into the other equation.

3x+4(-30+3x)=15

solve for x

X=7

Answer:

(6+x)(6-x)

Step-by-step explanation:

Use the difference of squares formula: a^2-b^2=(a+b)(a-b)

Here, a is 6 and b is x, so you just substitute it into the formula

Final answer:

To factor the expression 36 - x², we recognize it as a difference of squares and use the identity a² - b² = (a + b)(a - b) to get (6 + x)(6 - x).

Explanation:

The question involves factoring the expression 36 - x^2 as the product of two binomials. To factor this expression, observe that it has the form of a difference of squares. The difference of squares can be factored using the identity a² - b² = (a + b)(a - b). In this case, a^2 is 36 and b² is x², where a is 6 and b is x. Therefore:

36 - x² = (6² - x²) = (6 + x)(6 - x)

This is the factored form of the given expression as the product of two binomials.

Answer:

Around 16 hours

(16 hours, 2.74 minutes)

Step-by-step explanation:

In 3 hours,

Rachel has managed: 3 ÷ 5/2 = 6/5

In 6 hours,

Jenna has managed: 6 ÷ 9 = ⅔

Till 9 am,

Thomas and Paul have been woking and maneged:

(9 ÷ 7) ÷ (9 ÷ 2) = 81/14

Total works done in first 9 hours:

6/5 + 2/3 + 81/14 = 1607/210

Remaining work:

15 - 1607/210

= 1543/210

Rachel, Paul and Thomas complete this remaining job together in next 't' hours

(t/2.5) + (t/2) + (t/7) = 1543/210

73t/70 = 1543/210

t = 7.0456621 hours

Or 7 hours 2.74 mins

Overall, it will take them around 9+7 = 16 hours to complete the task

They'll be done at 1600

Which is 4 pm

Final answer:

It will take them approximately 22 hours and 21 minutes to build 15 tractors. The tractors will be finished at around 10:21 PM.

Explanation:

To find out how long it will take them to build 15 tractors, we need to first calculate how many tractors each person can build in 1 hour. Jenna can build 1/9 of a tractor in 1 hour, Thomas can build 1/7 of a tractor in 1 hour, Rachel can build 2/5 of a tractor in 1 hour, and Paul can build 1/2 of a tractor in 1 hour.

Adding up the fractions, we get 1/9 + 1/7 + 2/5 + 1/2 = 85/126. Therefore, in 1 hour, all four of them can build 85/126 of a tractor. To build a total of 15 tractors, we need to find how many hours it will take to build 126/85 of a tractor.

Therefore, it will take them (126/85) × 15 = 22.35 hours to build 15 tractors. Since they started building at midnight, it will take them about 22 hours and 21 minutes, so they will finish building the tractors at around 10:21 PM.

Answer:

(52, 32 )

Step-by-step explanation:

Given the 2 equations

y = x - 20 → (1)

x + y = 84 → (2)

Substitute y = x - 20 into (2)

x + x - 20 = 84, that is

2x - 20 = 84 ( add 20 to both sides )

2x = 104 ( divide both sides by 2 )

x = 52

Substitute x = 52 into (1) for corresponding value of y

y = 52 - 20 = 32

Solution is (52, 32 )

Answer:

1. P(N) =  3/5

2. P(R) =  2/5

3. P(N and R) = 1/4

4. P(N or R) = 3/4

Step-by-step explanation:

1. Let's review the information given to us to answer the problem correctly:

Number of students in a high school senior class = 500

Number of students that regularly wear a necklace = 300

Number of students that regularly wear a ring = 200

Number of students that wear a necklace and a ring = 125

2. What is P(N), the probability that a senior wears a necklace?

Let's recall the formula of probability:

Probability = Number of favorable outcomes/Total of possible outcomes

Substituting with the real given values:

P(N) = 300/500 = 3/5 (Dividing by 100 numerator and denominator)

P(N) =  3/5

3. What is P(R), the probability that a senior wears a ring?

Substituting with the real given values:

P(R) = 200/500 = 2/5 (Dividing by 100 numerator and denominator)

P(R) =  2/5

4. What is P(N and R), the probability that a senior wears a necklace and a ring?

Substituting with the real given values:

P(N and R) = 125/500 = 1/4 (Dividing by 125 numerator and denominator)

P(N and R) = 1/4

5. What is P(N or R), the probability that a senior wears a necklace or a ring?

P(N or R) = P(N) + P(R) - P(N and R)

Substituting with the real given values:

P(N or R) = 3/5 + 2/5 - 1/4

P(N or R) = 5/5 - 1/4

P(N or R) = 1 - 1/4

P(N or R) = 3/4

The probabilities are:

P(N) = 0.6
P(R) = 0.4

P(N and R) = 0.25

P(N or R) = 0.75.

Let's solve the given probabilities step-by-step using the provided information.

Step 1: Calculate P(N)

The probability that a senior wears a necklace, P(N), is calculated by dividing the number of students wearing a necklace by the total number of students.

Step 2: Calculate P(R)

The probability that a senior wears a ring, P(R), is calculated similarly by dividing the number of students wearing a ring by the total number of students.

Step 3: Calculate P(N and R)

The probability that a senior wears both a necklace and a ring, P(N and R), is given directly in the problem.

Step 4: Calculate P(N or R)

The probability that a senior wears either a necklace or a ring is given by the formula:

1. D

2. D

3. c

4. A

5. C

Answer:

6

Step-by-step explanation:

6+30=36

6^2=36

Answer:

the positive number is equal to  6.

Step-by-step explanation:

from the question which says A positive number is 30 less than its square. Find the number.

let the number be "n"

and the square of the number = n²

So, we have  the expression to be

n = n²-30

n ²-30 -n =0

Re-arrange the equation

n²-n-30=0

the factors of -30 are 5 and -6

so we have

(n+5)(n-6)=0

n+5 =0

n = -5

or

n-6 =0

n = 6

therefore the number can either be -5 or 6.

note we are asked to find the positive number , so the positive number is 6

Answer:

Avg. monthly expenses are $1,481.83

Step-by-step explanation:

Just took the test :)

Chandra's average monthly expenses are calculated by adding her total annual expenses for each category and then dividing by 12, yielding an average monthly expense of $1,481.83.

To calculate Chandra's average monthly expenses, we first need to sum up all the expenses for each month and then divide by the total number of months (12).

Adding all these up gives us the total annual expense:

$852 (cell phone) + $12,300 (rent) + $300 (gym) + $300 (internet) + $850 (auto insurance) + $1,440 (gas) + $1,740 (food) = $17,782 total annual expense.

To find the average monthly expense, we divide by 12:

$17,782 / 12 months = $1,481.83

Therefore, Chandra's average monthly expenses are $1,481.83.

Answer:

(6, 2)

Step-by-step explanation:

Flipped is equivalent to mirrored, so on the other side of the y axis should be a mirrored point equally far from 0, which is -6 and the value for y should be the same: 2.

The coordinates (-6,2) when flipped on the y-axis become (6,2), as the process involves changing the sign of the x-coordinate while keeping the y-coordinate same.

The coordinates (-6,2) when flipped on the y-axis will become (-(-6),2), which makes it (6,2). To understand why, we can refer to the principle of reflection in mathematics. Reflection of a point about the y-axis implies changing the sign of the x-coordinate while keeping the y-coordinate same. Here, the x-coordinate is -6, and when we flip or reflect on the y-axis, it changes its sign. Therefore, -(-6) becomes +6. The y-coordinate remains the same. Hence, -6 2 flipped on the y axis becomes (6, 2).

Step-by-step explanation:

For the given triangle, the tan of angle A equals C.

Step-by-step explanation:

Step 1:

For the given triangle, the hiking route is represented by AB and the change in elevation is represented by BC.

So we need to calculate the value of BC for the given triangle

Step 2:

In the given triangle, the opposite side has a length of 'a' feet, the adjacent side has a length of 'b' feet while the triangle's hypotenuse measures 400 feet.

To calculate the opposite side of the triangle, we can use the sine of any angle in that particular triangle. The sine of a particular angle is the opposite side's length divided by the hypotenuse's length.

sin A = [tex]\frac{oppositeside}{hypotenuse}[/tex] .

Step 3;

The length of the opposite side = a,

The length of the hypotenuse side = 400 units.

[tex]\sin A=\frac{a}{400}, \sin 25^{\circ}=0.4226[/tex]. So

[tex]0.4226=\frac{a}{400}, a=0.4226 \times 400[/tex] = 169.04 feet.

So the change in elevation is 169.04 feet.
