B. 49 cm 2
c. 96 cm 2
D. 24.5 cm 2
What is the approximate area of the circle shown below? - 1

Answers

Answer 1
Answer:

Answer:

Option A. 191cm²

The area of the circle is 191 cm²

Step-by-step explanation:

To solve this problem we need to use the area formula of a circle:

a = area

r = radius = 7.8cm

π = 3.14

a = π * r²

we replace with the known values

a = 3.14 * (7.8cm)²

a = 3.14 * 60.84cm²

a = 191.03 cm²

The area of the circle is 191.03 cm²

When negative five is subtracted from a number the result is 10 find the number15
5
-5
-15

Answers

Answer: second option.

Step-by-step explanation:

Let be "x" the unknown number.

According to the information provided in the exercise, 10 is the result of the subtraction of "x" and -5.

Based on this, you can write the following equation:

x-(-5)=10

To find the value of "x" you must remember the multiplication of signs:

(+)(+)=+\n(-)(-)=+\n(-)(+)=-

Then:

x-(-5)=10\n\nx+5=10

Finally, subtracting 5 from both sides of the equation, you get:

x+5-(5)=10-(5)\n\nx=5

Answer:

x - (-5) = 10

x = 5

My final answer is 5

2 -> 7; but 7 = 2 * 2 + 3;
3 -> 9; but, 9 = 3 *2 + 3;
4 -> 11; but, 11 = 4 * 2 + 3;
5 -> 13; but, 13 = 5 * 2 + 3;

The rule is : ( your number ) * 2 + 3;

The function rule is f( x ) = 2x + 3.

What is bigger 11/14 or 3/4?

Answers

Step 1: Reduce (simplify) entered fractions to lowest terms, if the case:
Fraction: 3 / 4 it's already reduced to lowest terms
Fraction: 11 / 14 it's already reduced to lowest terms

Step 2: Calculate LCM (lowest common multiple) of the reduced fractions' denominators, it will be the common denominator of the compared fractions:
Denominator 4, factored = 22
Denominator 14, factored = 2 * 7
LCM (4, 14) = 22 * 7 = 28

Step 3: Calculate each fraction's expanding number (LCM divided by each fraction's denominator):
For fraction: 3 / 4 is 28 : 4 = (22 * 7) : 4 = 7
For fraction: 11 / 14 is 28 : 14 = (22 * 7) : 14 = 2

Step 4: Expand fractions to bring them to the common denominator (LCM):
3 / 4 = (7 * 3) / (7 * 4) = 21 / 28
11 / 14 = (2 * 11) / (2 * 14) = 22 / 28

An inequality is solved the same way an equation is solved, with one exception. If an operation is performed that changes ordering, then the comparison symbol is reversed. The usual case is multiplication or division by a negative number:

  2 > 1

  -2 < -1 . . . . both sides multiplied by -1
