8. In the diagram, the measure of the arc from A to B not
passing through C is 80 degrees. What is the measure of
angle ACB?
A. 20 degrees
B. 40 degrees
C. 80 degrees
D. 160 degrees
Answers
Step-by-step explanation:
for the same arc, the angle at the circumference of the circle is half of the angle at the center of the circle.
and the arc angle is normally representing the angle at the center of the circle.
therefore, the
angle ACB = arc angle AB / 2 = 80/2 = 40°
so, B is the right answer.

A tank is 1/2 filled with water. some of the water is then poured into 8 small containers each with a capacity of 27 cubic centimeters. the tank is now 1.4 full. what is the capacity of the tank.
Answers
The capacity of the tank is 240 cm³.
What is capacity?Capacity means the volume of a solid shape.
To calculate the capacity of the tank, we use the formula below.
Note: When the water from the 8 small containers is poured into the tank that was initially half full, becomes 1.4 full that means the water from the 8 small containers fills the tank 0.9
Formula:
V = (8×27)/0.9............... Equation 1Where:
V = Volume or capacity of the tankSolve for V
V = 240 cm³.Hence, the capacity of the tank is 240 cm³.

Does anybody know this? Need it done soon. Find the surface area. Use 3.14 for pi. Do not round your answer
Answers
Answer:
113.04 yd²
Step-by-step explanation:
The formula for finding the surface area of a cylinder is:
2πrh+2πr² r = radius, h=height
The radius of this cylinder is 2, so you replace the 'r' with '2.' The height is 7 yd, so you replace the 'h' with '7.' Use 3.14 for π.
2πrh+2πr²
2(3.14)(2)(7) + 2(3.14)(2)^2
= 113.04 yd²

Please help me mi amor !!! I really need help
Answers
Step-by-step explanation:
it is really simple.
first of all, when 2 lines intersect (and we are talking straight lines, otherwise they are not lines in the mathematical sense), the angles created are the same in both sides of the lines (just left-right mirrored).
and secondly, the sum of all angles around a single point in one side of a line must be 180°, as the line can be considered the diameter of a circle, the point the center is the circle, and all the angles on one side are a half-circle.
so,
angle 3 = 37°
that means
angle 1 = 37° too
angle 2 is supplementary to e.g angle 3 (that means they both add up to 180° as explained above).
angle 2 = 180 - 37 = 143°
and angle 4 = 143° too

On the map at the right, the public swimming pool can be represented by the point (-6, 5) and Tim’s house can be represented by the point (1, 5). If each unit on the graph represents 0.5 miles, how many miles is Tim’s house from the pool
Answers
The distance between the swimming pool and Tim's house is 3.5 miles.
How to find the distance?
First, we need to find the distance between the two points, and then we multiply that by 0.5 miles.
The distance between the points (-6, 5) and (1, 5) is:
[tex]d = \sqrt{(-6 - 1)^2 + (5 - 5)^2} = 7[/tex]
Now, changing to miles, we get:
d = 7*0.5mi = 3.5mi
So the distance is 3.5 miles
