pays $64.99 plus $0.10 for each minute over 450 minutes for her cell phone plan. Which system
of equations represents this situation? Letx represent the number of minutes over 450

Answers

Answer:

D

Step-by-step explanation:

Samuel pays 59.99 for the 450 minutes but when he goes over he pays 0.25 for each minute he goes over. The same thing for Monica

The correct option is D

Given that,

Samuel pays $59.99 plus $0.25 for each minute over 450 minutes for his cell phone plan. Monica pays $64.99 plus $0.10 for each minute over 450 minutes for her cell phone plan.

Based on the above information, the equation is as follows:

y = 59.99 + 0.25x

y = 64.99 + 0.10x

Find the value of x that makes each parallelogram the given type

Answers

The value of x that will make each of the parallelogram the given type is:

11. x = 6.5

12. x = 3

What are Some Examples of Parallelogram?

A parallelogram is any quadrilateral whose opposite sides are parallel and equal to each other.

Examples of a parallelogram include:

RhombusSquareRectangle

11. The diagonals of a square intersect at right angles, therefore:

13x + 5.5 = 90

13x = 90 - 5.5

13x = 84.5

x = 84.5/13

x = 6.5

12. The four sides of a rhombus are equal in length, therefore:

14 - x = 2x + 5

14 - 5 = 2x + x

9 = 3x

9/3 = x

x = 3

Quadrilateral ABCD has vertices A ( 5,0) , B ( 3,6) , C (-3,6) , and D( -4, -5) . If ABCD is reflected in ×-axis, and then rotated by 90 degrees clockwise about origin to get a new quadrilateral A'B'C'D' , what is the distance between B' to C'. Enter the distance here

Answers

The final coordinates of B' and C' after the rotation are B''(6, -3) and C''(6, 3) while the distance between both points is; 6

Distance between B" and C" is;

B"C" = √[(6 - 6)² +(3 + 3)²]

B"C" = 6

What is the distance between coordinates?

We are given coordinates of vertices of Quadrilateral ABCD  as;

A ( 5,0) , B ( 3,6) , C (-3,6) , and D( -4, -5)

Reflection about the x-axis gives; B (3, 6) , C(-3, 6)

Now, the transformation rule for rotating 90 degrees clockwise is;

(x, y) becomes (y, -x)

Thus, coordinates B' and C' are now;

B''(6, -3) and C''(6, 3)

Distance between B" and C" is;

B"C" = √[(6 - 6)² +(3 + 3)²]

B"C" = 6

The correct option regarding the standard deviation of the residuals is given by:

The point will increase the standard deviation of the residuals because it has a large negative residual.

What are the mean and the standard deviation of a data-set?

The mean of a data-set is given by the sum of all values in the data-set, divided by the number of values.The standard deviation of a data-set is given by the square root of the sum of the differences squared between each observation and the mean, divided by the number of values.

Considering a scatter plot and a line of best fit, a residual is the difference between the observed value(scatter plot) and the predicted value(line of best fit).

Hence, the circled value has a large negative residual. For the standard deviation, the differences are squared, hence the circled value increasing the standard deviation, and the correct option is:

1. Is the square root of 14 a rational number? No, the square root of 14 is not a rational number. It is an irrational number as it cannot be expressed in the form of p/q.

2.−4 is an integer. We can say it is also a rational number, but it is neither a natural number, whole number, irrational number nor an imaginary number.

3. 3/8 is a rational number and a whole number because its more than 0

4. When a rational number is split, the result is a decimal number, which can be either a terminating or a recurring decimal. All rational numbers can be expressed as a fraction whose denominator is non-zero. Here, the given number, 3 can be expressed in fraction form as 3⁄1. Hence, it is a rational number.

A gallon of paint can cover 50 square feet. Find how many gallon containers of paint should be bought to paint 3 coats
on each wall of a rectangular room with dimensions 10 feet by 18 feet and walls that are 8-feet tall.

Answers

Answer:

27 gallons

Step-by-step explanation:

A rectangular room is a rectangular prism. The floor and ceiling are the bases. The walls are the lateral faces. The lateral are of a rectangular prism is the product of the perimeter of the base and the height of the prism.

lateral area = Ph

lateral area = 2(10 ft + 18 ft) × 8 ft

lateral area = 448 ft²

area of walls = 448 ft²

area of three coats = 3 × 448 ft² = 1,344 ft²

area covered by 1 gallon of paint = 50 ft²

number of gallons of paint needed = 1344 ft² / 50 ft² = 26.88
