Similarities:

They are both line segments.
They are both found in circles.
Radius is a half of diameter and diameter is twice the radius making them dependent.
Their intersection is always contains the center of the circle.
Their set intersection equals to radius and their set union equals to diameter.

Differences:

Diameter is longer (unless its 0)
Diameter touches two different points on the circumference while radius only one point
Center angle of diameter is 180° while of radius is 0° or 360°.
The Diameter is constructed via line
The Radius is constructed via line or ray

Difference would be that is a diameter is double a radius and a radius is half of a diameter.
A similarity would be that they would are within a circle and touch the center of circle

How can you use a 10-by-10 grid to model 12%? You can shade half of the squares. You can shade half of one row of the squares. Y

TiliK225 [7]

Answer:

The options provided do not have the correct answer. Read below.

Step-by-step explanation:

Given a 10 by 10 grid model means that there are exactly 100 individual squares present. This shows that each square is equal to 1%.

None of the options provided gives us 12% of the model.

The first option results in 50%, the second results in 5%, third option results in 0.5% and the last option results in 2%.

For 12% we can shade 12 squares completely, half of 24 squares etc.

I hope this answer helps.

Use the Law of Sines to find the missing angle of the triangle. Find m<b to the nearest tenth.

defon

1. By the Law of Sines, you have:

SinA/a=SinB/b=SinC/c

2. You don't need the fraction SinC/c, so you can eliminate it. Then:

SinA/a=SinB/b

A=40°
a=19
B=m∠b
b=13

3. When you substitute this values into SinA/a=SinB/b, you obtain:

SinA/a=SinB/b
Sin(40°)/19=SinB/13
SinB=13xSin(40°)/19
m∠b=SinB^-1(13xSin(40°)/19)
m∠b=26.1°

Therefore, the answer is: 26.1 degrees.
