Two angles are complimentary. The larger angle is 3 degrees less than twice the measure of the smaller angle. Find the measure o

f each angles.

Answer:

31 and 59

Step-by-step explanation:

Complimentary angles are angles which add to 90 degrees. The larger of the angles is "3 degrees less than twice the smaller". This is 2x-3. The smaller angle is x. Add them together and solve for x.

2x-3 + x =90

3x-3=90

3x=93

x= 31

The smaller angle is 31. The larger angle is 2(31)-3 = 59.

Mr. aba builds a circular patio with a diameter of 12 feet he covers the patio with paving stones the cost of the paving stones
Sedaia [141]
1.) Find the area of the circle:
• Formula: A=pi•r^2

- To find the area of a circle, we need to have the radius, and since the diameter is 2x the length of the radius, the radius is 1/2 of the diameter.

Finding the radius: r=d/2

r=12/2

r = 6.

- Now that we know that r=6, we can substitute it into the formula:
• A=pi•r^2

A=pi•(6)^2

A=113.097

- The area of the circle is 113.097ft.^2. We know that a square foot is $10.50. So, we have 113.097 square feet at $10.50/sq. foot. This means that we will add $10.50 113.097 times. Therefore:

113.097 • 10.50 = 1,187.518

So, total, it will cost $1,187.518

Taylor's computer randomly generate numbers between 0 and 4, as represented by the given uniform density curve.
MrRa [10]

12.5% is the percentage of numbers randomly generated by Taylor's computer that is less than 0.5.

An illustration of a numerical distribution with continuous results is a density curve. A density curve is, in other words, the graph of a continuous distribution. This implies that density curves can represent continuous quantities like time and weight rather than discrete events like rolling a die (which would be discrete). As seen by the bell-shaped "normal distribution," density curves either lie above or on a horizontal line (one of the most common density curves).

The percentage of numbers randomly generated by Taylor's computer are less than 0.5 is given by

P(0≤X≤0.5)

=\int_{0}^{0.5}\frac{1}{4}dx

=\frac{1}{4}x|^{0.5}_{0}

=\frac{1}{4}(0.5-0)

=0.25(0.5)

= 0.125

That is 12.5%

The circumference of a circle is 19π in. What is the area, in square inches? Express your answer in terms of π.
Lelu [443]

Answer:

A = 90.25 pi in^2

Step-by-step explanation:

The circumference is given by

C = 2*pi*r

19pi = 2*pi*r

Divide each side by 2 pi

19pi / 2 pi = 2*pi*r/ 2pi

9.5 = r

The area is given by

A = pi r^2

A = pi ( 9.5)^2

A = 90.25 pi in^2
