The image shows a circle with center (4,6) and radius 10 units.
A circle is a curve sketched out by a point moving in a plane. The point that lies on the circle is (-4, 12), (-6, 6), and (4, 16).
What is a circle?A circle is a curve sketched out by a point moving in a plane so that its distance from a given point is constant; alternatively, it is the shape formed by all points in a plane that are at a set distance from a given point, the centre.
The simple way to do such questions is to make the given circle and plot the points on the graph. As shown below.
The other way to do the question is to find the distance between the centre point of the circle and the point if it is equal to the radius of the circle, the point will lie on the circle, otherwise not.
The formula to find the distance between the two points on a graph is,
[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
Hence, the point that lies on the circle is (-4, 12), (-6, 6), and (4, 16).

At Shannon's Pancake House there are 228 dirty coffee mugs and 247 clean coffee mugs. What percentage of the coffee mugs at the pancake house are dirty? Write your answer using a percent sign
Answer:
48%
Step-by-step explanation:
First, we need to add the amounts together to be able to see what percent of all the cups are dirty. (228 + 247 = 475). Now we can find one percent of 475 we can do this by moving the decimal point two to the left. (4.75). so If 4.75 is 1% we can multiply 4.75 until we get 228.
4.75 x 20 = 95.
4.75 x 40 = 190
4.75 x 45 = 213.75
4.75 x 50 = 237.5
4.75 x 48 = 228
Since every time we multiplied by 1 more we went up 1%. We multiplied by 48 so 48%.

~150cm²
Step-by-step explanation:
cylinder surface area = 2 pi r h + 2 pi r²
Answer:
24π cm²
Step-by-step explanation:
Radius (r) = 3 cm
Height (h) = 5 cm
Surface area of cylinder
= 2πr (h + r)
= 2 × π × 3 (5 + 3)
= π × 3 (8)

Answer:
Carter family = 25 hours
Davis family = 31 hours
Step-by-step explanation:
Let's say the number of hours the Carter family used their sprinkler is x and the number of hours the Davis family used their sprinkler for is y.
So combined:
x + y = 45 hours
and we are also told that:
40x + 15y = 1300 L
So we can do simultaneous equations to solve the problem.
With some rearranging, we can figure out that:
y= 45 - x
and by substituting that into the second equation:
40x + 15 (45 -x) = 40x + 675 - 15x = 1300L
25x = 1300 - 675
25x = 625
x = 25 = hours that the Carter family used their sprinkler
and we can substitute that back into the original equation to find how many hours the Davis family used their sprinkler so:
25 + y = 56
y = 31
The Davis family used their sprinkler for 31 hours whilst the Carter family used their sprinkler for 25 hours.

The sum of all but one interior angle of a heptagon is 776°. What is the measure of the final interior angle? 42º 56º 124º 304º.
Answer:
124°
Step-by-step explanation:
the sum of the interior angles of a polygon is
sum = 180° (n - 2) ← n is the number of sides
here n = 7 ( heptagon has 7 sides ) , then
sum = 180° × 5 = 900°
let x be the final interior angle , then
776° + x = 900° ( subtract 776° from both sides )
x = 124°

The most likely object to weigh 4 tons will be Helicopter
The correct option is (D) Helicopter
What is ton in kg?1 ton = 1000 Kg
First, a watermelon weigh= 0.001 to 0.003 tons(i.e., 1-3 Kg)
then, A man weigh= 0.09 to 0.1 tons (i.e., 90 - 100kg)
A clothes dryer weigh= 0.07 to 0.09 tons (i.e., 70- 90 Kg)
lastly, a Helicopter weigh= 0.275- 56 tons (i.e., 275 - 56,000 Kg)
