Circumference and Area of Circles

Mathematics
1 answer:
yanalaym [24]4 years ago
8 0

Step-by-step explanation:

Area of a circle = #r^2

1256 = 3.14 × r^2

r^2 = 1256/3.14

r^2 = 400

Square root of r = 20

Diameter = 2 × r = 2 × 20 = 40 inches

If a line has a slope of 3, what is the slope of a perpendicular line?
pashok25 [27]

Answer:

Slope of perpendicular line is -1/3

Step-by-step explanation:

The slope of the given line is 3 and we have to find the slope of the perpendicular line.

We know that the slope of two perpendicular lines are negative reciprocal of each other.

In other words if the slope of the line is m then then slope of the perpendicular line is -\frac{1}{m}

The reciprocal of 3 is \frac{1}{3}

Hence, negative reciprocal of 3 is -\frac{1}{3}

Therefore, the slope of perpendicular line is -1/3

C is the correct option.

Camila drove 30 miles per hour to get to her math class. what is the dependent quantity
Naya [18.7K]
Equations with Independent and Dependent Variables
 Common Core Standard: Use variables to represent two quantities in a real-world problem that change in relationship to one another; write an equation to express one quantity, thought of as the dependent variable, in terms of the other quantity, thought of as the independent variable. Analyze the relationship between the dependent and independent variables using graphs and tables, and relate these to the equation.
 Dependent variable – is a variable that changes because of the other variable or depends on the other variable
 Independent variable –is a variable that is not impacted by other variables
 Dependent and independent variables are very common in the real world
 Example: Most coaches will say that the longer a player practices a sport the better the player will be at the sport.
o The dependent variable is the player’s ability, as it relies on the length of a practice
o The independent variable is the number of hours the player practices, because the player’s ability does not
impact the amount of time the player practice

PLEASE HELP! Image below
maria [59]

Answer:

1.6

Step-by-step explanation:

So, first, write down the number of jokers in each deck of cards.

That would be: 0, 1, 2, 2, 3

Then, add up all those numbers.

0+1+2+2+3=8

Now, divide that sum by the number of decks or cards shown in the data set, which would be 5.

8/5=1.6

So, the mean of the data in the dot plot shown is 1.6.
