Answer:
Step-by-step explanation: Since the given problem states that the two angles, angle 1 and angle 2 form a linear pair, this means that they form a 180° line, so that:
measure angle 1 + measure angle 2 = 180°
Since measure of angle 2 is six more than twice the measure of angle 1, therefore:
measure angle 2 = 2 (measure angle 1) + 6
hence, substituting this into the first equation:
measure angle 1 + 2 (measure angle 1) + 6 = 180
3 (measure angle 1) = 174
measure angle 1 = 58°
Therefore,
measure angle 2 = 2 (measure angle 1) + 6
measure angle 2 = 2 (58°) + 6
measure angle 2 = 122*
A cylinder made of lead has a height of 4 inches and a diameter of 2 inches. How heavy is the cylinder if lead weighs 0.4 pound per cubic inch? Round to the nearest tenth.
Answer:5.0
Step-by-step explanation:
The volume of a cylinder is [tex]\pi r^2h[/tex], since the radius is 1/2D, 2/2=1. Now, if [tex]\pi[/tex] is rounded to 3.14, the volume of the cylinder would be 1 x 1 x 3.14 x 4 = 12.56. Now, since there are 0.4 pound per cubic inch, 12.56 x 0.4 = 5.024. Rounded to tenth, the answer is 5.0 or 5.

how to find the circumference using 3.14
Answer:
c = 2 * 3.14 * r and c = 3.14 * d
Step-by-step explanation:
The formulas for the circumference of a circle are
c = 2πr and c = πd
where r is the radius and d is the diameter
using π = 3.14
the formulas become
c = 2 * 3.14 * r and c = 3.14 * d

a person's heart beats approximately 10^5 times each day. a person lives approximately 81 years. Work out an estimate for the number of times a person's heart beats in their lifetime
Answer:
29565x(10^5)
Step-by-step explanation:
heartbeat in 1 day=10^5.
we have 365 days in a year. it means that;
365x(10^5)=365x(10^5). this is heartbeat for 1 year.
then for 81 years,we multiply the value of 1 year heartbeat by 81.
=29565x(10^5).

The circle below has a radius of 10 inches. Find the area of Sector A and Sector C
Answer:
area of sector A = 47.97 in²
area of sector C = 109.03 in²
Step-by-step explanation:
area of full circle = πr² = (3.14)(10²) = 314 in²
area of sector A = (55/360)(314) = 47.97 in²
area of sector C = (314/2) - 47.97 = 109.03 in²
The owners of a smoothie shop want the price of each size smoothie to be proportional to the amount of liquid it contains. A small smoothie will be 16 fluid ounces and sell for $3.52
Answer:
?
Step-by-step explanation:
Whats the question?
The proportionality constant if, A small smoothie will be 16 fluid ounces and sell for $3.52 is 22.
What is proportionality?When the corresponding elements of two numerical sequences, frequently experimental data, have a fixed ratio, this is referred to as the coefficient of proportionality, and the two sequences are said to be proportional or directly proportional.
Given:
A small smoothie will be 16 fluid ounces and sell for $3.52,
Convert the price of the smoothie in cents as shown below,
The price of a smoothie = 3.52 × 100 ($1 = 100 cents)
The price of a smoothie = 352 cents
Calculate the proportionality constant as shown below,
The proportional constant = Fluid / price
The proportional constant = 352 / 16
The proportional constant = 22
Thus, The proportional constant is 22.

Tell whether 208 and 289 form a proportion
Answer:
You can tell if two fractions are proportional by using cross multiplication. Only equivalent fractions are proportional. To do this, multiply the denominator, the bottom number in the fraction, of the first fraction with the numerator, the top number in the fraction.
Step-by-step explanation:
The points (-6,-4) and (2,-2) fall on a particular line. What is its equation in point-stope
form?
Use one of the specified points in your equation. Write your answer using integers, proper
fractions, and improper fractions. Simplify all fractions.
Answer:
y+4= 1/4 * (x+6)
* = Multiply symbol...
Step-by-step explanation:
Point Slope formula is y-y1=m(x-x1)
All you have to do is plug those y's and x's in and you get most of your answer. The part with the actual math is that to find the m which is the slope, you have to do y2-y1/x2-x1. So 2/8 which simplified to 1/4. And BAM point Slope formula.

The polygons in each pair are similar. Solve for x.*
Answer:
X = 6
Step-by-step explanation:
Heights is 5x
Lengths is 6x
The solution for the x is 7 as per the concepts of similar polygons.
Given that the polygons in each pair are similar.
To find the value of x, we can set up a proportion between the corresponding side lengths of the two similar polygons.
We have the following proportion:
(6x - 7) / 42 = 25 / 30
To solve this proportion, we can cross-multiply:
30(6x - 7) = 42(25)
Simplifying further, we get,
180x - 210 = 1050
Next, we isolate the variable by adding 210 to both sides of the equation:
180x = 1260
Finally, we divide both sides by 180 to solve for x:
x = 1260 / 180
Simplifying:
x = 7
Therefore, the value of x is 7.

Irina is watching a 3 hour movie on TV. The shaded part of the fraction model below represents the part of each hour that the movie is playing, and the unshaded part represents the time spent on commercials.
Answer:
3 * 5/6 = 15/6 hours
Step-by-step explanation:
From the figure attached :
The bar is divided into 6 equal parts ; with 5 of the sections being shaded and 1 left unshaded
The shaded represent the actual playing time
Unshaded portion = time spent in commercials
Using the model, the actual playing time of the movie excluding commercials :
(Shaded portion / total portion) * movie length
5 / 6 * 3 = (5*3) / 6 = 15/6

a set of two concentric circles is shown above. What is the area of the shaded portion above?
Answer:
The answer is "[tex]44 \ m^2[/tex]"
Step-by-step explanation:
[tex]R=4.5 \ m \\\\r=2.5\ m\\\\[/tex]
The area between two concentrated circles via an exterior circle radius R and an internal circle
[tex]r =\pi(R^2-r^2)[/tex]
The region, therefore, consists of two concentrated circles with radii of 4.5 m and 2.5 m.
[tex]r=\pi(4.5^2 -2.5^2)\\\\[/tex]
[tex]=\frac{22}{7} (20.25-6.25) \\\\ =\frac{22}{7} (14) \\\\=22 \times 2 \\\\ =44 \ m^2[/tex]
