R'(2,-9) is the image of R after a reflection
in the line y = x. What are the coordinates
of R?

SOLUTION:

=) (4a)² + 18 = 118

=) 16a + 18 = 118

=) 16a = 118 - 18

=) a = 100/16

=) a = 6.25

Answer:

2.5

Step-by-step explanation:

(4a)^2 + 18 = 118

16a^2 = 100

a^2 = 100/16

a^2 = 25/4

a = 5/2 = 2.5

The cost price of this television set is equal to $447.87.

Given the following data:

To calculate the cost price:

In this exercise, you're required to determine the cost price of a television set that was sold for $421.

Mathematically, cost price is given by this formula:

[tex]Cost\;price = \frac{Selling\;price \times 100}{100-Percentage\;loss}[/tex]

Substituting the given parameters into the formula, we have;

[tex]Cost\;price = \frac{421 \times 100}{100-6}\\\\Cost\;price = \frac{42100}{94}[/tex]

Cost price = $447.87.

Step-by-step explanation:

To find the cost of the tip, we need to find 120% of 39.50.

120% = 100% (order) + 20% (tip)

Let's use fractions. 39.50 can be put over 1, and 120 can be put over 100.

Equation:

[tex]\frac{39.50}{1} \times \frac{120}{100} =?[/tex]

Multiply:

[tex]\frac{39.50}{1} \times \frac{120}{100} =\frac{4740}{100}[/tex]

Divide 4740 and 100 by 100:

[tex]\frac{4740 \div 100}{100 \div 100} = \frac{47.4}{1}[/tex]

Using the distance formula, the distance between (-3, 4) and (2, -3) is: 8.6 units.

Distance formula for calculating the distance between two points on a coordinate plane is given as: [tex]d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}[/tex].

Let,

(-3, 4) = (x1, y1)

(2, -3) = (x2, y2)

Plug in the values

[tex]c = \sqrt{(2 - (-3))^2 + (-3 - 4)^2} \\\\c = \sqrt{74} \\\\[/tex]

c = 8.6 units.

Therefore, using the distance formula, the distance between (-3, 4) and (2, -3) is: 8.6 units.

Answer:

y= -2x+1

Step-by-step explanation:

The slope of the line is -4/2, which gets simplified to -2. Then, the line passes through y-intercept (0,1), which becomes +1 as the y-intercept in y=mx+b form. Therefore, the equation is y= -2x+1. I'm 100% sure this is right. Hope that helps :)

According to the diagram:-

Exterior angle is equal to the sum of two opposite interior angle

[tex] \angle D + \angle \: E = ext \angle C \\ 6x + 8 + 5x + 8 = 82 \\ 11x + 16 = 82 \\ 11x = 82 - 16 \\ 11x = 66 \\ x = \frac{66}{11} \\ x = \frac{ \cancel{66}^{ \: \: 6} }{ \cancel{11} } \\ x = 6[/tex]

The value of x from the figure is 6

The sum of the interior angles of a triangle is equal to its exterior

Acording to the figure shown;

6x + 8 + 5x + 8 = 82

11x = 82 - 16

11x = 66

Divide both sides by 11

111x/11 = 66/11

x = 6

Hence the value of x from the figure is 6

Step-by-step explanation:

these are multiplications.

you could also write

4 + 5×(p - 1)

now, we need to calculate the contents of brackets (if we can), then do the multiplications and divisions, before we can do the then remaining additions and subtractions.

if we cannot do a calculation directly (because there is a variable involved), we need to do and document the single steps for the individual parts involved.

so,

4 + 5×(p - 1) = 4 + 5×p + 5×-1 = 4 + 5p - 5 = 5p - 1

remember, a multiplication of 2 expressions is done by multiplying every term of one expression with every term of the other expression and adding the results up (by considering their individual signs, of course).

Answer:

Volume: 198in³

Step-by-step explanation:

L x W x H

length x width x height

Length = 8in

Width = 4 1/2in or 4.5in

Height = 5 1/2in or 5.5in

8 x 4.5 x 5.5 = 198in³

Answer:

198 inches cubed

Step-by-step explanation:

The formula for volume for a rectangular prism is V=whl or volume equals width x height x length. I'm personally not a huge fan of fractions, so I convert 4 1/2 to 4.5 and 5 1/2 to 5.5. If you multiply 4.5 (the width), 8 (the length), and 5.5 (the height) together, you get 198 inches cubed.

Answer:

21

Step-by-step explanation:

Let x = number of t-shirts

Let y = total cost

If the company charges $3 per shirt, plus a $50 flat fee for shipping:

⇒ y = 50 + 3x

If the school spends $113 total, subtitute y = 113 and solve for x:

⇒ 113 = 50 + 3x

⇒ 113 - 50 = 3x

⇒ 63 = 3x

⇒ x = 63 ÷ 3

⇒ x = 21

Therefore, the choir bought 21 t-shirts

Solution:

Note that:

Solve the equation to find out how many shirts did the school choir bought.

The school choir bought 21 shirts.

From the question, we understand that the new poster design is to be drawn by reflecting the urn (i.e. the red figure) across the line x = 1

The line x = 1 is a vertical line that passes through the x-axis at x = 1.

To reflect the urn across x = 1, we simply flip the urn over the line.

We will subtract 28.8°F from 30.9°F and then reverse our answer.

30.9°F - 28.8°F = 2.1°F

= -2.1°F.

Answer: -2.1°F

The correct answer is -2.1°F. You do this by simply subtracting 28.8 by 30.9. When doing this, you get -2.1. So the temperature at midnight was -2.1°F.

Answer:

1999 The most points scored in an NHL career is 2,857, achieved by Wayne Gretzky (Canada) while playing for the Edmonton Oilers (Canada), Los Angeles Kings, St Louis Blues and New York Rangers (all USA) from 1979 to 1999. The points total comprises 894 goals and 1,963 assists in 1,487 games.

Step-by-step explanation:

a) Wayne Gretzky's average points per game is approximately 1.9202.

b) Wayne Gretzky would have scored approximately 151.5438 more points if he had played 79 more games.

a) To calculate Wayne Gretzky's average points per game, we divide the total points scored (2857) by the total number of games played (1487):

Average points per game = Total points scored / Total games played

Average points per game = 2857 / 1487 ≈ 1.9202

Wayne Gretzky's average points per game is approximately 1.9202.

b) To find out how many more points Wayne Gretzky would have scored if he had played 79 more games, we can use the average points per game calculated in part (a).

We know that his average points per game is approximately 1.9202. So, to find the additional points in 79 games, we can multiply the average points per game by the number of additional games:

Additional points = Average points per game * Additional games

Additional points = 1.9202 * 79 ≈ 151.5438

Wayne Gretzky would have scored approximately 151.5438 more points if he had played 79 more games.
