Substitute 11, -9, 12 in place of h, k and r respectively.

Triangle EFG has vertices E(-2, 1), F(-1, 4), and G(3, 4). Graph the figure and its image after a clockwise rotation of 90° about vertex F. Then write the coordinates of triangle E'F'G'.

The measure of the angle shown is 280°

From the question, we are to determine the measure of the angle shown

For the given protractor,

The measure between any two lines is 10°.

Also, there are 10 tick marks between any two lines.

∴ 15 tick marks will have a measure of 15°

Then,

The measure of a protractor showing an angle going through the fifteenth tick mark after two hundred sixty five degrees will be

265° + 15° = 280°

Hence, the measure of the angle shown is 280°

Answer:  The probability of picking a black bead is 4/7, because there are 4 black beads out of seven.  But if you took the first black bead out of the equation then the probability is now 3/7.

Answer:

angle A is 63 degrees,

angle B is 57 degrees

Step-by-step explanation:

first, let's create the equation. Pretty simple, because angles a and b become 120 degrees when added up, this this will become:

2x+3+2x-3=120

now, we make it simpler. In this case, just add up the numbers that we can add up. this eventually becomes:

4x=120

now, all we need to do is divide 120 by 4, which becomes 30. So, x=30.

substitute the 30 into the x in the original equation, and this becomes:

60+3+60-3=120

63+57=120

thus, angle A is 63 degrees, and angle b is 57 degrees.

The lines that represent the following system of linear equations.

2s +1.5y = -60

2s + y = -50

The equation of a straight line is a relationship between x and y coordinates, The general equation of a straight line is y = mx + c, where m is the slope of the line and c is the y-intercept.

Slope is a ratio of change in y-coordinate w.r.t. change in x-coordinate. The net change in y coordinate is written as, Δy and the net change in x coordinate is written as, Δx.

Given,

System of linear equations

2s +1.5y = -60

2s + y = -50

After plotting both the graphs we can see that, point of intersection is  (-15, -20)

Hence, The point of intersection is (-15, -20)

The median is 6.5.

The first quartile is 5.

The third quartile is 8.

The interquartile range is 3.

The numbers in the dot plot are: 4, 4, 4, 4, 5, 5, 6, 6, 6, 6, 7, 7, 7, 8, 8, 8, 9, 9, 9, 22

Median is the number in the middle of the dataset.

Median = 1/2 ( n + 1)

1/2 x 21 = 11.5th number = (6+ 7) / 2 = 6.5

First quartile = 1/4 x (n + 1)

1/4 x 21 = 5.25th number = 5

Third quartile = 3/4 x (n + 1)

Answer:

9x7=63

Step-by-step explanation:

just use a calculator for multiplication

The product of 9 and 7 is 63. In other words, the result of multiplying 9 and 7 is 63.

To find the result of multiplying 9 and 7, by follow a step-by-step process.

First, start by writing the multiplication expression as 9 multiplied by 7.

Next, multiply the digit in the ones place of the first number (9) with the digit in the ones place of the second number (7).

In this case, 9 multiplied by 7 equals 63.

Then, move to the tens place of the second number (7) and multiply it with the digit in the ones place of the first number (9).

Since there is no digit in the tens place of the first number, skip this step.

Finally, add the products obtained from the previous steps.

In this case, there is only one product, which is 63.

Therefore, the result of multiplying 9 and 7 is 63.

Multiplication is a fundamental arithmetic operation used to determine the total value when a number is repeated a certain number of times. In this case, multiplying 9 by 7 represents adding nine 7s together.
