Which of the following correctly shows the length of each radius, the point where the circles intersect, and the equation of the tangent line at this point?
Answer:
Length of the radii of the circles → 4 units and 1 unit
Equation of common tangent → x = 4
Step-by-step explanation:
From the figure attached,
Length of radii of each circles are,
Radius of circle S = 4 units
Radius of circle T = 1 unit
Common point where the circles are touching → (4, 1)
Common tangent to these circles is a line perpendicular to x-axis passing through x = 4,
Equation of the tangent will be,
x = 4

5x + 19.95 = 35
Solve x
Answer:
X = 3.01
Step-by-step explanation:
To solve for x, you first need to get x by itself. So you would minus 19.95 from both sides. Which would then be
5x = 15.05
Again x is not by itself so you would divide both sides by 5, the eqation would then be
x = 3.01
Which is the answer. If you want you can double check your work by putting the answer back in the eqaution.
5(3.01) + 19.95 = 35
If the statement is true that means you have the right answer
15.05 + 19.95 = 35
35 = 35
We are correct! Hope this helps with your question and how to do others like it.

for triangle FGH, angles F and G are known, as is the length of side h. Which method should be used to start solving triangle FGH?
- neither law can be used
- law of sines
- law of cosines
- both laws can be used
Answer:
Law of sines
Step-by-step explanation:
i took the test
The law of sines can be used to calculate the side h. Hence, option B is correct.
What is trigonometry?The branch of mathematics sets up a relationship between the sides and the angles of the right-angle triangle termed trigonometry.
For triangle FGH, angles F and G are known, as is the length of side h. The sin angle is the ratio of the perpendicular to the hypotenuse we can calculate one side by using the sine angle.
Hence, Hence, option B is correct.

On the main floor of the Kodak Hall at the Eastman Theater, the number of seats per row increases at a constant rate. Lucas counts 31 seats in row 3 and 37 seats in row 6. How many seats are there in row 20?
67
61
63
65
Answer:
67
Step-by-step explanation:
There are 65 seats in row 20, option D is correct.
Given that number of seats in row 3 are 31.
Number of seats in row 6 are 37
We need to find the rate of increase, we can calculate the difference in the number of seats between row 6 and row 3 and divide it by the number of rows in between:
Rate of increase = (Number of seats in row 6 - Number of seats in row 3) / (6 - 3)
Rate of increase = (37 - 31) / (6 - 3)
Rate of increase = 2
So, the number of seats increases by 2 seats per row.
To find the number of seats in row 20, we can use the rate of increase:
Number of seats in row 20 = Number of seats in row 3 + (Rate of increase × (20 - 3))
Number of seats in row 20 = 31 + (2× (20 - 3))
= 31 + (2 × 17)
= 31 + 34
= 65
Therefore, there are 65 seats in row 20.

What is the length of a day-night cycle? Is it the same everywhere on Earth?
12 hours - yes; because the sun rises and sets in the exact same place every day
relative to Earth.
12 hours - no; because depending on where you are on Earth, you have a
different amount of sunlight.
24 hours - yes; because the sun rises and sets in the exact same place every day
relative to Earth
24 hours - no; because depending on where you are on Earth, you have a
different amount of sunlight.
Answer: 24 hours - no; because depending on where you are on Earth, you have a different amount of sunlight.
Step-by-step explanation:
The day-night cycle is a complete day or a complete rotation of the earth around its axis. This takes 24 hours which is why 24 hours is the length of a full day.
People around the world however, do not get the same amount of sunlight or darkness and this is because of where they are on Earth. Due to the way the planet is tilted on its axis, some areas see sunlight more than other in a period and others see more darkness.

Answer:
31
Step-by-step explanation:
The entire straight line is 180 degrees. So, if angle a is 25 degrees we would subtract that from 180. This would give us 155 degrees. You would then add 2x and 3x together to get 5x. 155/5x would be 31. Your x value is then 31.
Answer and Step-by-step explanation:
We know that a is equal to 25.
Let's subtract that from the entire angle measure of line segment AB, which is 180.
180 - 25 = 155.
Now, we need to find the value of x. We can do this by adding together the other two angles, and equal it to 155.
155 = 2x + 3x
155 = 5x
31 = x
So, the value of x is 31.
