Mathematics

Percent means "per 100", so 50% means 50 per 100, or simply <span>50/100</span>

If you divide 50 by 100 you get 0.5 (a decimal number).

So, to convert from percent to decimal: divide by 100, and remove the "%" sign.

7/28 in simplest form

\frac { 7 }{ 28 }

28 is 4 times 7, so we will rewrite it like that.

28=4\cdot 7\\ \\ \frac { 7 }{ 28 } =\frac { 7 }{ 4\cdot 7 }

7 is 7 times 7, so we will rewrite it like that.

\frac { 7 }{ 28 } =\frac { 7 }{ 4\cdot 7 } =\frac { 1\cdot 7 }{ 4\cdot 7 } =\frac { 1 }{ 4 } \cdot \frac { 7 }{ 7 } =\frac { 1 }{ 4 } \cdot 1=\frac { 1 }{ 4 }

So the simplest form is,

\boxed { \frac { 1 }{ 4 }  }

Janice is thinking of two numbers. She says that two times the first number plus the second number is 41. In​ addition, the firs
Rudiy27
Let one of the number be x and the other be y

<span>two times the first number plus the second number is 41
</span>2x + y = 41

<span>the first number plus three times the second number is 73
x + 3y = 73

</span>2x + y = 41 --------- (1)
x + 3y = 73 --------- (2)

From (1):
2x + y = 41
y = 41 - 2x ------- sub into (2)
x + 3(41-2x) = 73
x + 123 - 6x = 73
x -6x = 73 - 123
-5x = -50
x = 10 -------- sub into (1)
2 (10) + y = 41
20 + y = 41
y = 41 - 20
y = 21

Ans: x = 10, y = 21

In a unit circle, the radian measure of the central angle is equal to the length of the ______
inn [45]

Answer:

A. Intercepted arc.

Step-by-step explanation:

From Geometry we know that arc (s), dimensionless, is measured by the following equation:

s = \theta \cdot r (1)

Where:

\theta - Central angle, measured in radians.

r - Radius, dimensionless.

If the circle has a radius of 1. Then, we notice that arc is directly proportional to the central angle. Hence, the right answer is A.
