What is the circumference of a circle with a radius of 2.5 m?

The circumference of a circle is always calculated by 2 $\pi$ R
So if R=2.5 m this circumference is 2* $\pi$ *2.5 m
Which is 5 $\pi$ m (choice B)

Hope this helped!

Solve the inequality for x. Show each step of the solution. 10x>8(3x-2)-12

Anettt [7]

Answer:

x < 2

Step-by-step explanation:

Given

10x > 8(3x - 2) - 12 ← distribute parenthesis on right side

10x > 24x - 16 - 12, that is

10x > 24x - 28 ( subtract 24x from both sides )

- 14x > - 28

Divide both sides by - 14, reversing the inequality symbol as a result of dividing by a negative quantity.

x < 2

Answer:

$m\angle D=64^{\circ}$

Step-by-step explanation:

Given

$\triangle ABE\sim \triangle TCD$

Similar triangles have conruent corresponding angles, so

$m\angle A=m\angle T=61^{\circ}\\ \\m\angle B=m\angle C=55^{\circ}\\ \\m\angle E=m\angle D$

The sum of the measures of all interior angles of the triangle is always equal to 180°, so

$m\angle T+m\angle C+m\angle D=180^{\circ}\\ \\61^{\circ}+55^{\circ}+m\angle D=180^{\circ}\\ \\m\angle D=180^{\circ}-61^{\circ}-55^{\circ}=64^{\circ}$
