Answer:
arc VU = 44º
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:
arc SVU = arc SV + arc VU 164º = 120º + arc VU arc VU = 164º - 120º = 44ºAlex runs on the track at school each Weekday morning . If he runs 5.9 miles each day, about how much does he run every month?
Answer:
118 miles
Step-by-step explanation:
Assuming that a month has 4 weeks
Each week has 5 weekdays.
The number of weekdays in a month is the number of weeks times 5.
4 X 5 = 20
Multiply the number of weekdays in a month by 5.9 miles.
20 X 5.9 miles = 118 miles
Therefore he runs 118 miles every months.
If 5 tractors can plow a field in 4 hours, how many hours will it take 3 tractors to plow the field?
It will take 3 tractors approximately 2.4 hours to plow the field.
Explanation: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.
Explanation: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.

Answer:
30 mmStep-by-step explanation:
The formula of an area of a circle:
[tex]A=\pi r^2[/tex]
r - radius
We have
[tex]A=706.9\ mm^2[/tex]
Substitute:
[tex]\pi r^2=706.9[/tex] divide both sides by π
[tex]r^2=\dfrac{706.9}{\pi}[/tex] use π ≈ 3.14
[tex]r^2\approx\dfrac{706.9}{3.14}\\\\r^2\approx225\to r=\sqrt{225}\\\\r= 15\ mm[/tex]
The diameter d = 2r.
Therefore
[tex]d=2(15)=30\ mm[/tex]
Answer:
30mm
Step-by-step explanation:
A=[tex]\pi[/tex][tex]r^{2}[/tex]
Substitute 706.9 for A and [tex]\pi[/tex] for 3.14
706.9= 3.14[tex]r^{2}[/tex] divided both sides by 706.9
when you divided 3.14 by 3.14 it will cross and when you divide 706.9 by 3.14 it will give you 225.

A plane is thrown. After 2 seconds is has gone 15 feet. After 7 seconds it has gone 55 feet. Find average rate of change of the plane.
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]

Hanley made 14 out of 35 shots in his last basketball game. What percent did he shoot ?
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.
Best of Luck!
What decimal is bigger 0.33 or 0.34
To determine which decimal is bigger between 0.33 and 0.34, we compare the digits after the decimal point. Since the hundredths place in 0.34 is 4 and in 0.33 is 3, 0.34 is the larger decimal.
Explanation:The question is asking to compare two decimals to determine which is larger. To compare 0.33 and 0.34, you look at the digits from left to right. Both numbers have a 0 before the decimal point, so you compare the digits after the decimal point. First, you compare the tenths place, the digit immediately after the decimal point. In both numbers, this digit is 3, so they are equal up to this point. Next, you look at the hundredths place, the next digit to the right. In 0.33, the digit is 3, while in 0.34, the digit is 4. Because 4 is greater than 3, 0.34 is the larger decimal.
Final answer:
0.34 is larger than 0.33 because the digit in the hundredths place is greater for 0.34.
Explanation:
When comparing two decimals, 0.33 and 0.34, we can determine which is larger by examining the digits from left to right. Here, both numbers have 0 before the decimal point and a '3' in the tenths place, but they differ in the hundredths place. Since 4 is greater than 3, the decimal 0.34 is larger than 0.33. To compare 0.33 and 0.34, we can look at the digits to the right of the decimal point. In this case, 0.34 has a larger digit than 0.33, so it is bigger.

A parabola has its vertex at (2, 1) and crosses the x-axis at (1,0) anu al l
the equations below has this parabola for its graph? (TEKS A2.4B-R)
ui...
Ay=1-(x - 2)^2
C y = -1 - (x + 2)^2
Dy= -1 - (x - 2)^2
B
y = 1 + (x + 2)^2
Answer:
A
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
Here (h, k) = (2, 1), thus
y = a(x - 2)² + 1
To find a substitute (1, 0) into the equation
0 = a(1 - 2)² + 1
0 = a + 1 ( subtract 1 from both sides )
a = - 1
Hence
y = - (x - 2)² + 1 or
y = 1 - (x - 2)² → A
The equation of the parabola with its vertex at (2, 1) and that crosses the x-axis at (1, 0) is y=1-(x - 2)^2.
Explanation:The vertex form of a parabola's equation is y=a(x-h)^2+k where (h, k) is the vertex. Here, the vertex is given as (2, 1). Also, it crosses the x-axis at (1,0), which makes it a downward-facing parabola(as y=0 when x=1), and hence, 'a' is negative. Now, we can compare the given options with these details.
Option A: y=1-(x - 2)^2 perfectly matches our requirements, because it's in the correct vertex form, and 'a' is negative (-1) which corresponds to a downward parabola.
So, the equation of the parabola with its vertex at (2,1) and that crosses the x-axis at (1,0) is y=1-(x - 2)^2.

is y=2/7x proportional?
In the equation y=2/7x, y is directly proportional to x.
To determine if the equation y = (2/7)x represents a proportional relationship, you can check if it fits the criteria for proportionality. In a proportional relationship, the ratio between y and x should remain constant. This means that if you double x, y should also double, and so on.
In the equation y = (2/7)x, the coefficient 2/7 is a constant, and it is the same for all values of x.
Therefore, this equation represents a proportional relationship.
In this case, if you double the value of x, the value of y will also double, and if you triple x, y will also become three times its original value, and so on. This is a key characteristic of a proportional relationship.
