Write a two column proof

Answer:  

Explanation:

The angle STV is an inscribed angle, i.e. an angle with its vertex (point T) on a circle and formed by two intersectic chords.

As per the inscribed angle therorem, this angle is half the central angle.

Thus, the central angle is 82º × 2 = 164º.

That central angle is the measure of the arc SVU.

By the construction, the measure of the arc SV plus the measure of the arc VU is equal to the measure of the arc SU.

Thus, you have:  

Answer:

The slope formed using points (4,6) and (8,0) is [tex]\dfrac{3}{2}[/tex]

Step-by-step explanation:

Given as :

The points are (4,6) and (8,0)

([tex]x_1[/tex] , [tex]y_1[/tex]) = (4,6)

([tex]x_2[/tex] , [tex]y_2[/tex]) = (8,0)

Let The slope that formed = m

So,

slope = m = [tex]\dfrac{y_2 - y_1}{x_2 - x_1}[/tex]

m =  [tex]\dfrac{0 - 6}{8 - 4}[/tex]

Or, m =  [tex]\dfrac{6}{4}[/tex]

∴ m = [tex]\dfrac{3}{2}[/tex]

So, The slope formed using points = m =  [tex]\dfrac{3}{2}[/tex]

Hence , The slope formed using points (4,6) and (8,0) is [tex]\dfrac{3}{2}[/tex] Answer

Scale on a map is the ratio between map distance and actual distance on Earth's surface. For the given question, the scale is found to be approximately 1 cm representing 1.33 km.

Explanation:

Scale on a map is the ratio between the distance on the map and the actual distance on Earth's surface. In this question, a scale of 3 cm representing 4 km means the ratio is 3 cm to 4 km. To find the scale, divide the map distance by the actual distance: 3 cm / 4 km = 0.75 cm/km. Therefore, the scale of the map is 1 cm representing approximately 1.33 km.

Answer:

[tex]\frac{3}{12} ,\frac{8}{12}[/tex]

Step-by-step explanation:

Given fraction: 1/4 and 2/3

To find common denominator, we will use Least common divisor (LCD) of 4 and 3.

[tex]4= 2\times 2\\3= 3\times 1[/tex]

∴ Least common divisor (LCD) = [tex]4\times 3= 12[/tex]

Now, to make denominator common for both the fractions, we need to multiply denominator with a number equal to 12.

∴ [tex]\frac{1}{4} =\frac{?}{12}[/tex]

Multiply numerator and denominator by 3

[tex]\frac{1\times 3}{4\times 3} = \frac{3}{12}[/tex]

Next solving for another fraction:

[tex]\frac{2}{3} =\frac{?}{12}[/tex]

Multiply numerator and denominator by 4

[tex]\frac{2\times 4}{3\times 4} = \frac{8}{12}[/tex]

∴ We have [tex]\frac{3}{12}\  and \ \frac{8}{12}[/tex] with common denominator.

Step-by-step explanation:

The measure of arc AE is

AE = 360° - (100 + 40 + 60)° = 360° - 200° = 160°

∠ BCD = 0.5( m arc AE - m arc BD ), that is

x = 0.5(160 - 40) = 0.5 × 120 = 60

Answer:

75 degrees

Step-by-step explanation:

Complementary angles add up to 90 degrees. If we are given that one angle is 15 degrees, we can find the other one using a simple one-step equation.

let x represent the measure of angle N

90 = 15 + x

Subtract 15 from both sides to isolate the variable

75 = x

Angle N measures 75 degrees

Answer:

average rate of change of the plane = average speed = [tex]\frac{40}{5} =8\frac{feet}{s}[/tex]

Step-by-step explanation:

we know that

average rate of change of the plane = average speed of the plane

average speed = (change in distance)/(change in time)

since th goes from 15 feet to 55 feet from 2 seconds to 7 seconds

change in time = final time - initial time = 7-2 = 5 seconds.

change in distance = final distance - initial distance

                                = 55-15 = 40 feet.

therefore average speed = [tex]\frac{40}{5} =8\frac{feet}{s}[/tex]

Answer:

320 cubes

Step-by-step explanation:

3 1/3 inches = 10/3 inches

There are 10 lengths of 1/3 inch in 10/3 inches.

2 2/3 inches = 8/3 inches

There are 8 lengths of 1/3 inch in 8/3 inches.

1 1/3 inches = 4/3 inches

There are 4 lengths of 1/3 inch in 4/3 inches.

In the 3 1/3 inch by 2 2/3 inch by 1 1/3 inch box, you can place 10 by 8 by 4 cubes measuring 1/3 inch on the side.

10 * 8 * 4 = 320

Answer: 320 cubes

It will take 320 cubes of size 1/3 inch  to fill the box a box with a width of 3 1/3 inches, a length of 2 2/3 inches, and a height of 1 1/3 inches

Volume of a cube of side a inch is [tex]\rm a^3\; inch^3[/tex]

Length of one side of the cube = 1/3 inch

[tex]\rm Volume\; of \; the \; cube = (1/3)^3 = 1/27 \; inch^3[/tex]

[tex]\rm Length\; of \; the \; box = 3 \dfrac{1}{3}\; inches = \dfrac{10}{3}\; inches[/tex]

[tex]\rm Width\; of \; the \; box = 2 \dfrac{2}{3}\; inches = \dfrac{8}{3} \; inches[/tex]

[tex]\rm Height\; of \; the \; box = 1 \dfrac{1}{3}\; inches = \dfrac{4}{3} \; inches[/tex]

[tex]\rm The\; volume \; of \; cuboid\; = \; Length\times Width \times Height\\\\So \; the \; volume \; of\; the\; box = (10/3)\times (8/3) \times (4/3)[/tex]

Let there be n be the number of cubes in the box so

Sum of volumes of n cubes = Volume of the box

[tex]\rm n \times (1/27 ) = (10/3)\times (8/3)\times (4/3)\\n \times (1/27) = 320 /27\\n = \bold{320}[/tex]

So, It will take 320 cubes of size 1/3 inch  to fill the box a box with a width of 3 1/3 inches, a length of 2 2/3 inches, and a height of 1 1/3 inches.

It will take 3 tractors approximately 2.4 hours to plow the field.

To find out how many hours it will take 3 tractors to plow the field, we can use the concept of work rates.

Given that 5 tractors can plow the field in 4 hours, we can set up a proportion:

5 tractors / 4 hours = 3 tractors / x hours

Cross-multiplying, we have:

5(x) = 3(4)

Simplifying, we get:

5x = 12

Dividing both sides by 5, we find that x = 2.4 hours.

Therefore, it will take 3 tractors approximately 2.4 hours to plow the field.

It would take one tractor 20 hours to plow the field, so with the combined rate of three tractors, it will take them approximately 6.67 hours to plow the field together.

The subject of this question is work-rate problems in Mathematics. To solve this problem, we must first determine the rate at which a single tractor can plow the field. If five tractors can plow a field in four hours, then one tractor would take five times as long, or 20 hours, to plow that same field alone.

Knowing this, we can now calculate how long it would take three tractors to plow the field together. Since one tractor takes 20 hours to plow the field, the rate of one tractor is 1 field per 20 hours. Therefore, three tractors would work at a rate of 3 fields per 20 hours, and so, it will take them 20/3, or approximately 6.67 hours to plow the field together.

0.222222222 is the exact decimal.

Answer:

There are 9 terms, and the common difference is 11.

Step-by-step explanation:

The sum of the first n terms of an arithmetic sequence is:

S = n (a₁ + aₙ) / 2

where a₁ is the first term and aₙ is the last term.

252 = n (-16 + 72) / 2

n = 9

The nth term of an arithmetic sequence is:

aₙ = a₁ + d (n−1)

where d is the common difference.

72 = -16 + d (9−1)

d = 11

There are 9 terms, and the common difference is 11.

To find the number of terms and the common difference of an arithmetic progression, you can use the formulas for the sum of an arithmetic progression and the last term. In this case, there are 10 terms in the AP and the common difference is 8.

The first step is to understand that the sum 'S' of the first 'n' terms of an arithmetic progression (AP) can be given by this formula: S=n/2(2a+(n-1)d). Here 'a' is the first term, 'd' is the common difference, and 'n' is the number of terms.

From the question, we know that S=252, a=-16, and the last term is 72. The last term can be expressed as a+(n-1)d, hence 72=-16+(n-1)d.

Solving these two equations we get n=10, meaning there are 10 terms in the AP, and d=8, the common difference.

To determine Jordan's unit rate of swimming, divide the number of laps by the minutes taken. If Jordan swims 2 laps in 4 minutes, the unit rate is 0.5 laps per minute. This concept is widely applicable, enabling comparisons of performance across different contexts.

Jordan can swim 2 laps in a given number of minutes. To find Jordan's unit rate of laps per minute, we would simply divide the number of laps by the number of minutes. For example, if Jordan swims 2 laps in 4 minutes, the unit rate would be 0.5 laps per minute.

To find a unit rate, you always divide the first quantity (number of laps) by the second quantity (time in minutes), ensuring you have a rate reflective of one unit of time. This unit rate can then be used to calculate how many laps Jordan could swim in a different given time frame.

Examples of Unit Rates

Unit rates are beneficial for comparing performance and can apply to various scenarios like estimating how long it would take to fill a swimming pool or determining the velocity of a common garden snail.

/2 and /4 because angle 1 is 90

Complementary angles in Mathematics are two angles that add up to 90 degrees. You determine this by adding the measures of two angles; if the sum is 90, the angles are complementary. An example would be angles of 30 and 60 degrees.

In the field of Mathematics, specifically geometry, complementary angles are two angles that add up to 90 degrees. Without the diagram, it's tricky to provide an accurate pair of complementary angles. Nevertheless, if you have pairs of angles in the diagram, you calculate their sum: if it equals 90 degrees, those angles are complementary. For example, if one angle measures 30 degrees and the other measures 60 degrees, those two angles are complementary because they add up to 90 degrees.

Answer: 40%

Step-by-step explanation: To find out what percent of shots Hanley made in the last basketball game, we need to write 14/35 as a percent.

To write a fraction as a percent, first remember that a percent is a ratio of a number to 100. So to write 14/35 as a percent, we need to find a fraction equivalent to 14/35 with a 100 in the denominator. We can do this by setting up a proportion.

So we have [tex]\frac{14}{35} = \frac{n}{100}[/tex]

Now, we can use cross products to find the missing value.

1,400 = 35n

÷35      ÷35   ← divide by 35 on both sides of the equation

   40 = n

This means that Hanley made 40% of his shots last basketball game.

To find the percentage of how many shots Hanley made, we can divide how many shots he made to how many shots he took.

14 ÷ 35 = 0.4

Multiply by 100 to find the percentage.

0.4 * 100% = 40%

Thus, Hanley made 40% of his shots.
