Answer:

3. It is likely.

Step-by-step explanation:

Let's assume the dartboards circles have radius of r, 2r, 3r and 4r from inner side

Then the areas covered will be as:

point 20 = πr² = S
point 15 = π(2r)² - πr² = 3πr² = 3S
point 1 0 = π(3r)² - π(2r)² = 5πr² = 5S
point 5 = π(4r)² - π(3r)² = 7πr² = 7S

Total area of the dartboard is S+3S+5S+7S = 16S

The area of point 5 is 7S. And the area of non- 5 point is 16S - 7S = 9S

The probability of scoring at least 10 points is:

9S/16S = 0.5625

As it is between 1/2 and 1, the probability is in 'likely' region

So the correct answer choice is: 3. It is likely

Lines a and b are parallel. line c is perpendicular to both line a and line B. Which statement about lines a,b and C is not true

7nadin3 [17]

When lines are parallel, they have the same slope, so the statement "line a and line b have the same slope" is TRUE

When lines are perpendicular, the slopes are opposites (the sign and number is flipped)

For example:

slope is 2

perpendicular line's slope is -1/2

slope is -1

perpendicular line's slope is 1/1 or 1

slope is 4/5

perpendicular line's slope is -5/4

When you multiply(the product) perpendicular slopes together, they equal -1. Since line c is perpendicular to line a and line b, the product of their slopes is -1.(so this is true)

The statement "the sum of the slopes of line a and b is 0" is false because if they have the same slope, when added together the result would not be 0. The slopes of line a and line b is -2/3, so the sum would be -4/3.

Sum : $(5 x+1)$

Term : 1, $5x$ and $3y$

Product : $9(5x+1),5x$ and $3y$

Factor : 5 and x, 3 and y, 9 and 5x+1

Quotient : $\frac{9(5x+1)}{3y}$

Coefficient : 5 is the coefficient of x and 3 is the coefficient of y.

Explanation:

The expression is $\frac{9(5x+1)}{3y}$

Sum: Sum is the result of addition of terms.

Thus, from the expression,

Sum = $(5 x+1)$

Term : A term is a single number or a variable or a number multiplied with a variable.

Thus, from the expression,

Term = 1, $5x$ and $3y$

Product : Product is the result of multiplication of numbers.

Thus, from the expression,

Product = $9(5x+1),5x$ and $3y$

Factor : The numbers that are multiplied is called a factor.

Thus, from the expression,

Factor = 5 and x, 3 and y, 9 and 5x+1

Quotient : Quotient is the result of dividing two numbers or variables.

Thus, the given whole expression is a quotient.

Hence, Quotient = $\frac{9(5x+1)}{3y}$

Coefficient : Coefficient of a variable is a number multiplied with a variable.

Thus, from the expression,

Coefficient : 5 is the coefficient of x and 3 is the coefficient of y.

If the perimeter of a square is 5 feet now many Inches long is each side of the square

gogolik [260]

Answer:

Well since we know that the perimeter of a square is four times the length of one of its sides. We just have to divide 5 by 4 to get the length of one side:

5feet /4 sides = 1.25 feet

And to finish off, we have to convert feet to inches:

1 foot = 12 inches

1.25 feet x inches

x inches = 12 inches x 1.25 feet ÷ 1 foot

x inches = 15 inches

Therefore, each side is 15 inches long.

Hope this helps!
