Point M (5,-7) is the midpoint of the line segment CD. If C is (2, "-3)," which of these are the coordinates of D?

Answer:

1.6 kg = $2.96

Step-by-step explanation:

The given statement is,

→ 1 kg of apple = $1.85

→ a = 1.85

Now the cost of 1.6 kg of apple is,

→ 1.6 × a

→ 1.6 × 1.85

→ $2.96

Hence, 1.6 kg of apple is $2.96.

Based on the definition of perpendicular bisector, the value of b = 5.

A perpendicular bisector can be described as any line that bisects another line segment at right angles.

This means, the measure of the angles at the point of bisection are right angles (90 degrees).

Therefore:

12b + 30 = 90 [definition of perpendicular bisector]

Solve for b

12b + 30 - 30 = 90 - 30

12b = 60

Divide both sides by 12

12b/12 = 60/12

b = 5

After solving the Algebraic expression we gets Tim needs 3.05 lbs. and 2.95 lbs. Metal.

Algebraic expressions are constructed using integer constants, variables, and the addition, subtraction, multiplication, and division operations of basic arithmetic.

To form the Algebraic expression

Let x be the quantity of silver at 29% and y the quantity at 80%

Then x*28% + y*61% = 6*54%

and x + y = 6

 Let y = 6-x then

29*x + (6-x)*80= 324

29*x + 480- 80*x = 324

51*x = 156 and x = 156/51 = 3.05 lbs.

so y = 6 - x = 2.95 lbs.

Hence,

The set of information that is true about the relation is:

Domain: {3, 4, 5, 6}

Range: {-8, -1, 2, 7}

The relation is not a function.

A relation that represents a function will have each of its domain elements related to exactly one range element.

All the x-values in a relation are referred to as the domain of a function, while all the y-values are called the range of the function,

Therefore, for a relation to be considered a function, a domain element must not correspond to two different range elements or related to two range elements.

Given the relation, {(3, 2), (5, −1), (6, 7), (3, −8), (4, 2)}:

The domain of the relation is: {3, 4, 5, 6}

The range of the relation is: {-8, -1, 2, 7}

A.The length of each path is 130 meters.

Given:

The park resembles an isosceles trapezoid.

Figure shows a trapezium . AC and BD are diagonals. The length of BD is 14x plus 4, and AC is 11x plus 31.

we know that:

Diagonals are equal in isosceles trapezoid.

14x + 4 = 11x + 31

14x - 11x = 31 - 4

3x = 27

divide by 3 on both sides

3x/3 = 27/3

x = 9

Diagonal length = 14x + 4.

= 14*9 + 4

= 126 + 4

= 130 meters.

The simple interest is $420 and the maturity value is $$6,720

Using this formula to find the simple interest

Simple interest = Principal  × Interest rate × Time

Where:

Principal = $6300

Interest rate =4% or 0.04

Time = 20 month = 20/12 = 1.6666666

Let plug in the formula

Simple interest = $6,300 × 0.04 × 1.6666666

Simple interest = $420

Using this formula to find the maturity value

Maturity value = Principal + Interest

Maturity value = $6,300 + $420

Maturity value = $6,720

Therefore the interest is $420.

After solving, 50% is her hourly overtime rate.

In the given question,

India works overtime, she receives an hourly rate of 1-times her regular hourly 1/2 rate.

We have to find her hourly overtime rate.

India is working overtime so her regular hourly rate is 1/2.

Evaluating the expression

We find her hourly overtime rate in percentage.

She receive overtime rate for 1 time is 1/2 rate.

We can write 1/2 as 0.5.

To express it as percentage we multiply and divide by 100.

= 0.5 × 100/100

= 50%

The correct expression of the inequality expression is 18 ÷ 6 + 3 □ 6 + 12 ÷ 3

From the question, the expression is given as

18 ÷ 6 + 3 □ 6 + 12 ÷ 3

We start by converting the above expression to the same form

So, we start by solving the quotients

This gives

3 + 3 □ 6 + 4

Next, we evaluate the sum

So, we have

6 □ 10

In the above expression, we have

6 and 10

By convention, the number 6 is less than the number 10

This is so because 6 has a smaller value and 10 has a higher value

When the above numbers are compared, we have

6 is less than 10

This means that we make use of the inequality symbol <

When is a standard normal random variable, the probability of P(–1.20 ≤ z ≤ 1.50) is 0.8181.

The probability illustrates the likelihood of events.

From the information, it's important to note that P(–1.20 ≤ z ≤ 1.50) will be:

= P(Z ≤ 1.50) - P(Z ≤ -1.20)

= P(Z ≤ 1.50) - [1 - P(Z ≤ -1.20)]

It should be noted that by using the normal z table, the probability of the corresponding z score will be 0.9332 and 0.8849.

The required equation  can be used to determine the pounds of laundry the customer brought in is A. 0.61x + 28.00 = 41.42

An equation is a mathematical expression that shows the relationship between two variables.

To find the given equation,

Let x be the number of pounds of clothes washed and folded at the laundromat.

Given that the laundromat will wash and fold clothes at $0.61 per pound for those customers with a laundry service, the total amount paid for the number of poundsof clothes is P = rate × number of pounds = $0.61 × x = 0.61x

Also, the laundromat has a wash-and-fold service for a monthly fee of $28.00.

So, the total amount paid is T = P + $28.00 = $0.61x + $28.00

Now, since one customer paid $41.42 in total for the month, since this is the total amount paid, then T = $41.42

So, $0.61x + $28.00 = $41.42

So, the required equation is A. 0.61x + 28.00 = 41.42

A and C are congruent angles opposite to congruent sides of the isosceles triangle.

Find the measure of ∠A

Answer:

The angle A is 55°.

Step-by-step explanation:

We know that,

→ <A = <C

Now the value of x will be,

→ 3x + 40 = x + 50

→ 3x - x = 50 - 40

→ 2x = 10

→ x = 10/2

→ [ x = 5 ]

Then the value of m<A is,

→ A = 3x + 40

→ A = 3(5) + 40

→ A = 15 + 40

→ [ A = 55° ]

Hence, the answer is 55°.

A total of 9 workers are needed to finish the same task in 4 days

From the question, we understand that:

3 workers can complete a certain task in 12 days

This means that

3 workers = 12 days

The proportionality constant is then calculated as

Proportionality constant = Number of workers x Number of days

Substitute the known values in the above equation So, we have the following equation

Proportionality constant = 3 * 12

Evaluate

Proportionality constant = 36

When the number of days is 4, we have

Days = 4

So, we have

Proportionality constant = Number of workers x Number of days

This gives

36 = Number of workers x 4

Divide both sides by 4

Number of workers = 9
