a. What is the circumference of the
largest circle that can be cut from a
square measuring 30 cm on a side?
Use 3.14 for Pie


b. What percent of the perimeter of the
square is the circumference of the
circle?

Answers

Answer 1

Answer:

a) 94.2 cm

b) 78.5%

Step-by-step explanation:

a) since the square side = 30 cm

it means the diameter = 30 cm

then circumference of the largest circle that can be cut = 3.14×30 = 94.2 cm

b) the perimeter of the square = 30×4 = 120

94.2 for 120

x% for 100%

x = (100×94.2)/120 = 9420/120 = 942/12 = 78.5%

The following two triangles are similar. Find x.

Answers

Answer and Step-by-step explanation:

Since we know that the triangles are similar, we can find the value of x. It appears that the lighter triangle is dilated to be smaller than the darker triangle.

So, We would divide 48 by 6 to find the scale factor.

48 divided by 6 is 8.

Now, we divide 56 by 8 to find x.

56 divided by 8 is 7.

x is equal to 7.

Anthony took a taxi from his house to the airport. The taxi company charged a pick-up fee of $2.60 plus $3 per mile. The total fare was $35.60, not including the tip. Write and solve an equation which can be used to determine xx, the number of miles in the taxi ride.

Answers

Answer:

Equation: 35.60 = 2.60 + 3x

It was 11 miles

Step-by-step explanation:

35.60 = 2.60 + 3x

3x = 33

x = 11

The linear function for the fare is:

[tex]F(x) = 2.6 + 3x[/tex]

Solving the equation, it is found that the taxi ride was of 11 miles.

A linear function for a cost considering a distance of x miles has the following format:

[tex]F(x) = F(0) + ax[/tex]

In which

F(0) is the fixed cost.a is the cost per mile.

In this problem:

Pick-up fee of $2.60, thus [tex]F(0) = 2.6[/tex]Cost per mile of $3, thus [tex]a = 3[/tex].

The function is:

[tex]F(x) = 2.6 + 3x[/tex]

Fare of $35.60, thus [tex]F(x) = 35.60[/tex] and we solve for x to find the number of miles.

[tex]35.6 = 2.6 + 3x[/tex]

[tex]3x = 33[/tex]

[tex]x = \frac{33}{3}[/tex]

[tex]x = 11[/tex]

There were 11 miles in the taxi ride.

The denominator of the first term is a difference of squares, such that

4a ² - b ² = (2a)² - b ² = (2a - b) (2a + b)

So you can write the fractions as

(4a ² + b ²)/((2a - b) (2a + b)) - (2a - b)/(2a + b)

Multiply through the second fraction by 2a - b to get a common denominator:

(4a ² + b ²)/((2a - b) (2a + b)) - (2a - b)²/((2a + b) (2a - b))

((4a ² + b ²) - (2a - b)²) / ((2a - b) (2a + b))

Expand the numerator:

(4a ² + b ²) - (2a - b

(4a ² + b ²) - (4a ² - 4ab + b ²)

4ab

So the original expression reduces to

4ab / ((2a - b) (2a + b))

or

4ab / (4a ² - b ²)

upon condensing the denominator again.

Paul will roll two standard dice simultaneously. If Event A = both dice are odd and Event B = at least one die is even, which of the following best describes events A and B?

Answers

Answer:

Mutually Exclusive

Dependent

Step-by-step explanation:

Given that both events cannot occur at the same time, that is "both dice cannot be odd (event A) if at least one of the dice is even (event B).

Hence, this is MUTUALLY EXCLUSIVE.

Also, given the fact that the occurrence of one event (event A) affects the probability of the other (event B).

Hence, this is DEPENDENT.

Answer:

[tex]40\frac{5}{8}mm^2[/tex]

Step-by-step explanation:

To find the area of a triangle, one must use the formula,

[tex]\frac{base*height}{2}[/tex]

It is given that

- base = [tex]9\frac{3}{4}[/tex]

-height = [tex]8\frac{1}{3}[/tex]

Substitute in the values and solve;

[tex]\frac{9\frac{3}{4}*8\frac{1}{3}}{2}[/tex]

In order to multiply the two fractions, one must convert them from mixed number form to improper fraction form. This can be done by multiplying the denominator (the number under the fraction bar), by the "number" part of the mixed number, and then adding the result to the numerator (the number over the fraction bar;

- base = [tex]9\frac{3}{4}=\frac{(9*4)+3}{4}=\frac{36+3}{4}=\frac{39}{4}[/tex]

- height = [tex]8\frac{1}{3}=\frac{(8*3)+1}{3}=\frac{24+1}{3}=\frac{25}{3}[/tex]

Substitute,

[tex]\frac{\frac{39}{4}*\frac{25}{3}}{2}[/tex]

Cross simplify,

[tex]\frac{\frac{325}{4}}{2}[/tex]

Further simplify,

[tex]\frac{325}{4}*\frac{1}{2}\\\\= \frac{325}{8}[/tex]

Convert back to a mixed number divide the numerator by the denominator, write the whole-number result as the number outside of the fraction, and the remainder as the numerator of the fraction,

[tex]40\frac{5}{8}[/tex]

The diagonals of square ABCD intersect at point E. If BE = 2x + 1, and AC = 3(6x-4), find BD.

Answers

Answer:

X=1

BD=AC=3(6x-4)=3(6(1)-4)=6

BD=6

Square is a polygon with 4 equal sides. The value of line BD is 6 units.

What is a square?

A square is a polygon with 4 sides, such that all the four sides of the polynomial are equal, also all the angles of the square are of 90°.

As it is given that the diagonals of square ABCD intersect at point E. And, we know that the diagonals of the square bisect each other. therefore, we can write,

BD = 2BE

Substituting the values, we will get,

[tex]3(6x-4) = 2 \times(2x+1)\\\\18x-12 = 4x+2\\\\18x-4x = 2+12\\\\14x = 14\\\\x = \dfrac{14}{14}\\\\x = 1[/tex]

Thus, the value of x is 1.

We know that the diagonal of a square are equal, therefore, the value of the diagonal BD can be written as,

[tex]BD = AC = 3(6x-4)[/tex]

Substitute the value of x as 1, therefore, the value of BD can be written as,

[tex]BD = 3[6(1)-4]\\\\BD = 3(6-4)\\\\BD = 3 \times 2\\\\BD = 6[/tex]

Hence, the value of line BD is 6 units.
