Given the two concentric circles with center H below, find the area of the shaded region. Round your answer to the nearest tenth if necessary.
Answer:
A ≈ 194.8 units²
Step-by-step explanation:
the shaded area (A) is calculated as
A = area of outer circle - area of inner circle
= πr₁² - πr₂² (r₁ is outer radius and r₂ the inner radius )
= π × 13.5² - π × 4.5²
= π(13.5² - 4.5²)
= π(182.25 - 20.25)
= π × 62
≈ 194.8 units² ( to the nearest tenth )

Which of the following tables does NOT represent a function?
Answer:
C.
Step-by-step explanation:
In a function, one x-value must have just one y-value assigned to it. So in short, C is the only table that does not represent a function because it has two values of Y (-3, and -1) for one value of x (1).

Answer: Counter, 0, 0.
Step-by-step explanation:
Think about a clock. The hand of a clock goes clockwise. When you tighten something (righty tighty) you spin it clockwise. You can rotate an object, lets say a square, clockwise. You can also rotate it counterclockwise, in the other direction. Therefore, you can rotate an object clockwise and counterclockwise.
You can rotate a figure around any point, such as the center of the figure, the origin, or anywhere else. One common place to rotate a figure around, such as a square, is the origin. This is the center of the coordinate plane. This point is not up, down, left, or right at all from the center. This coordinate is (0, 0). Therefore, the next two blank spaces should both be filled with 0.
The blank spaces should look like this:
One direction is clockwise and the other is counterclockwise.
...
This can be any coordinate point such as the origin which is at ( 0 , 0 )
When factored, the trinomials x2 + 2x − 15 and x2 + 7x + 10 have one binomial factor in common. What is this factor?
Answer:
(x+5)

The set of all points in a plane that lie the same distance from a single point in the plane.
Explanation:
Imagine that you have a rope staked into the ground at one end. The other end is allowed to move freely. At this freely moving endpoint, imagine white chalk is spread on the grass. The chalk would draw out a circle. Each point on the white chalk circle is the same distance away from the center.
Another example: we have a campfire and campers gather around it. The fire itself is the center. The campers would be on the edge of the circle if they are the same distance away from the fire (eg: all of them 5 feet away from the fire).
Find the volume of this prism.
41 cm?
11 cm
Answer:
41cm^2×11cm=451cm^3
Step-by-step explanation:
You need to multiply the surface of the 'base' with height
Answer: 451 cm³
Step-by-step explanation: the rule of the volume is base times height so multiply 41
times 11 so the answer is 451 . The units is to the power of 3 in finding volume of figures . The hexagon is the base and the rectangle is the height so multiply their lengths and don't forget the units . Hope this helps .

Answer: A:2 R8
This image should help, but first, you should find the biggest number that 27 can be multiplied by, but stay under 62, which in this case is 2, because 27*3=81 and 2 is the maximum it can be while staying below 62. which makes the equation turn into 62-54=8, making the remainder 8.

I=PRT/100I=470(4/3)(9)/100I=47(12)/10I=47(6)/556.5$Step-by-step explanation:
Interest can be calculated by formula,
» I = Prt
where,
p = principalr = annual interest ratet = time (yrs)Given:
Principal - 470Rate - 10%time - 40 daysTo find:
Interest?Solution:
Time in yrs so :- 40/365 = 8/73
Rate :- 10/100
Calculating Interest
I = Prt» I = 470* 8/73* 10/100
» I = 47* 8/73
» I = 5.15
Austin is participating in a 30k race. He runs at an average speed of 10 kilometers per hour and walks at an average speed of 6 kilometers per hour. He wants to complete the race in 4 hours. Let x represent the number of hours he runs. Let y represent the number of hours he walks.
What equation in standard form relates x and y to the goal of covering 30 kilometers? (no spaces)
Using the relation between velocity, distance and time, the equation that relates x and y is given by:
x + y - 3 = 0.
What is relation between velocity, distance and time?Velocity is distance divided by time, hence:
[tex]v = \frac{d}{t}[/tex]
In this problem, he wants to run 30 km at a rate of 10 km per hour, hence:
[tex]10 = \frac{30}{t}[/tex]
10t = 30
t = 3.
The total time is 3 hours. Considering x as the number of hours he runs and y the number of hours he walks, along with the total time, the equation is given by:
x + y = 3.
In standard form:
x + y - 3 = 0.

10. Select all true statements.
A. All rectangles are squares.
B. All rectangles are parallelograms.
C. All rhombuses are parallelograms.
D. All squares are rectangles.
E. All squares are rhombuses.
F. All trapezoids are parallelograms.
The correct answers are:
B, D, and E.
A parallelogram is a quadrilateral with both pairs of opposite sides parallel.
A rectangle is a parallelogram with all right angles, so yes, every rectangle is a parallelogram.
A square is a parallelogram with all right angles and all congruent sides; since it is a parallelogram with all right angles, every square is a rectangle.
A rhombus is a parallelogram with all congruent sides.
Since a square is a parallelogram with all congruent sides, then every square is a rhombus.
A trapezoid is a quadrilateral with one pair of parallel sides. Since a rhombus is a parallelogram, with 2 pairs of parallel sides, rhombus are not trapezoids.
