Hi there!
If KLM is an isosceles triangle, then KM = LM.
4d - 13 = 12 - d
Solve for d. Add 'd' to both sides:
5d - 13 = 12
Add 13 to both sides:
5d = 25
Divide both sides by 5:
<u>d = 5 units.</u>
Answer: 250π m³
Step-by-step explanation:
I took the quiz!!
The answer is 11.25 mm.
A diameter of a circle is twice of its radius: d = 2r ⇒ r = d/2
small circle large circle
radius: r1 radius: r2 = ?
diameter: d1 = 15 mm
⇒ r1 = d1/2 = 15/2 mm
Since t<span>he ratio of the radii of two circles is 2:3, we have:
r1 : r2 = 2 : 3
which can also be expressed as:
</span>

<span>
We know that r1 is 7.5, so let's implement it:
</span>

Let's multiply both sides of the by 3r2:

⇒

Answer:
the correct choice is marked
Step-by-step explanation:
The elements are 1, 4, {4}, {9}. That is, any subset that includes 1 must include it without braces. Any subset that includes 9 must include it with braces.
{4, {9}, 1} is a subset of A
Answer:
C. 2 = 37
Step-by-step explanation:
<2 and 37 are vertical angles and vertical angles are equal
Angle 1 and 37 form a straight line so they add to 180
<1 + 37 = 180
<1 = 180-37 = 143
Angle 3 and 37 form a straight line so they add to 180
<3 + 37 = 180
<3= 180-37 = 143
