Answer:
C. a quantity used as a standard measurement
Step-by-step explanation:
A unit is a universally acceptable system of measurement. The system is majorly referred to as the international standard of units i.e (SI) units.
Since physical quantities could be categorize as either fundamental or derived. The use of units in measurement is very essential, because it relates the magnitude measured to the physical quantity.
The units of measurement tells what physical quantity has been measured.
1-2x is the answer since 2 times x is twice the number subtracted from 1
Answer:
<em>y = 12</em>
Step-by-step explanation:
<u>Congruent Triangles:</u>
ABC and CBD are congruent triangles because:
* They have one right angle.
* They share one side
* They have one congruent angle (BD is the bisector of triangle ABC)
This implies that sides AD and DC have the same length, thus:
3y + 6 = 5y - 18
Subtracting 6:
3y = 5y - 18 - 6
Subtracting 5y:
3y - 5y = - 18 - 6
Simplifying:
-2y = -24
Dividing by -2:
y = -24 / (-2)
y = 12
<u>STEP 1 </u>
Since AB = CD , M is the midpoint of AB , and L is the midpoint of CD
then OM = OL
2x - 3 = x + 5 → x = 8
OM = 2x - 3 → OM = 2(8) - 3 → OM = 16 - 3 → OM = 13
<u>STEP 2</u>
Since AB = 60 and M is the midpoint of AB
then MB = 30
<u>STEP 3</u>
Draw a line from O to B to create triangle OMB. Notice that OM is perpendicular so M is a 90° angle, so the Pythagorean Theorem can be used.
OM² + MB² = OB²
13² + 30² = OB² <em>substituted from steps 1 and 2</em>
169 + 900 = OB²
1069 = OB²
32.7 = OB
Realize that OB is the radius.
Answer: 32.7
