Mathematics High School

Can someone help me out with this question as I’m completely stuck

Answers

Answer 1

Answer:

Step-by-step explanation:

∠BEF = ∠ABE {Alternate interior angle}

∠BEF = 60

∠EQR = ∠ BEF {Corresponding angles}

∠EQR = 60

In ΔEQR

∠QER + ∠EQR + ∠ERQ = 180 {angle sum property}

80 + 60 +x = 180

140 + x = 180

x = 180- 140

x = 40

Given A(5, –2), what are the coordinates of (T⟨−3, 4⟩∘ Rx-axis)(A)?

Answers

Answer:

not sure

Step-by-step explanation:

Following are the calculation to the given coordinates:

[tex]\to T (-2, 5)[/tex]

The y-axis reflection:Modify its abscissa's sign, i.e., the x-coordinate.Keep this ordinate, which would be the y-coordinate.

[tex]\to[/tex] (-2, 5) is the image (-2, -5).

Also, as a result, the coordinates of point T' after the Ry-axis are as follows: (2, 5).

Whenever a point is reflected throughout the x-axis, the x-coordinate is unchanged, but the "y-coordinate" is assumed to be the additional inversion.

[tex]\to[/tex] (-2, 5) is the image (-2, -5).

As a result, the coordinates of point T' after the Rx-axis are just as follows: (-2, -5)

A circle is dilated by a scale factor of 1.5 to create a new circle. The area of the new circle is 1.5 times the area of the original circle.

True or false??

Answers

Given:

The given statement is "A circle is dilated by a scale factor of 1.5 to create a new circle. The area of the new circle is 1.5 times the area of the original circle."

To find:

Whether the given statement in true or false.

Solution:

Area of circle is

[tex]A=\pi r^2[/tex]

Where, r is the radius of the circle.

Let [tex]r_1[/tex] be the radius of the original circle. So, the area of the circle is

[tex]A_1=\pi (r_1)^2[/tex]

The circle is dilated by a scale factor of 1.5 to create a new circle. So, the radius of the new circle is:

[tex]r_2=1.5r_1[/tex]

The area of the new circle is

[tex]A_2=\pi (r_2)^2[/tex]

[tex]A_2=\pi (1.5r_1)^2[/tex]

[tex]A_2=2.25\pi (r_1)^2[/tex]

[tex]A_2=2.25A_1[/tex]

The area of the new circle is 2.25 times the area of the original circle.

Therefore, the given statement is false.

8 18

To find:

The slope of the line that described by the data in the table.

Solution:

Consider any two points from the given table.

Let the two points are (0,8) and (4,13). So, the slope of the line is

[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]

[tex]m=\dfrac{13-8}{4-0}[/tex]

[tex]m=\dfrac{5}{4}[/tex]

[tex]m=1.25[/tex]

Therefore, the slope of the line described by the data in the table is 1.25.

Solve:
14x+y=7
Write your answer in the following format:
with no spaces.

Answers

Answer:

x = 7/10; y = 21/5

Step-by-step explanation:

y = 6x

4x + y = 7

Since the first equation is already solved for y, we can easily use the substitution method. We substitute 6x for y in the second equation and solve for x.

4x + y = 7

4x + 6x = 7

10x = 7

x = 7/10

Now we use the first equation and substitute 7/10 for x and solve for y.

y = 6x

y = 6 * 7/10

y = 42/10

y = 21/5

Answer: x = 7/10; y = 21/5

Bob wants to order some books from an online bookstore. Each book costs 16.50 and shipping for the entire order is a flat rate of 25.03. Bob can spend no more than 78.00

Answers

Answer:

Bib can buy no more Than 3 books

Step-by-step explanation:

Given that:

Cost per book = 16.50

Total shipping = 25.03

Total budgeted amount = 78

The number of books, x that can be ordered can be represented by the inequality :

16.50x + 25.03 ≤ 78

16.50x ≤ 78 - 25.03

16.50x ≤ 52.97

x ≤ 52.97 / 16.50

x ≤ 3.210

Bib can buy no more Than 3 books
