A rectangular field has an area of 1,764 m2. the width of the field is 13 m more than the length. what is the perimeter of the field? 121 m 144 m 168 m 170 m
The Perimeter of the Field with a rectangular area of 1764 m² and the given width is; D: 170 m
What is the perimeter of the rectangle?We are given;
Area of rectangle; A = 1764 m²
We are told that the width of the field is 13 m more than the length. Thus;
W = L + 13
Thus;
L(L + 13) = 1764
L² + 13L = 1764
Using quadratic equation calculator;
L = 36 m
Thus;
W = 36 + 13
W = 49
Perimeter = 2(L + W)
Perimeter = 2(49 + 36)
Perimeter = 170 m

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.
a water storage tank has a cylindrical shape. the base has a radius of 7 ft and a height of 15 ft. how much water can the tank hold at its maximum?
radius= 7ft
height= 15ft

solution:[tex]volume \: of \: cylinder = {\pi \: r}^{2} h[/tex]
[tex] = \pi \times {7}^{2} \times 15[/tex]
= 2309.07
therefore, the tank can hold 2309.07L of water as its maximum.
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).

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.

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).
Point p divides segment ab in the ratio AP:PB = 8:12. Which letter marks the location of point p?
A. Point k
B. Point L
C. Point M
D. Point N
The point P is located on the second partition, when segment AB is divided into 5 subsegments
How to determine the location of point P?The ratio is given as:
AP : PB = 8 : 12
Simplify the ratio i.e. divide by 4
AP : PB = 2 : 3
The above ratio means that when the segment AB is divided into 5 equal segments, the point P is located on the second partition

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 )

how do you calculate the average speed of a car that travels one mile at 30 mph and the second mile at 60 mph
Answer:
40mph
Step-by-step explanation:
use the speed = distance/time formula.
1. The first car has a speed of 30mph and travels one mile so the equation can be written as 30mph = 1/t.
Rearrange to get t = 1/30
1/30 of an hour is 2 minutes.
2. The second car has a speed of 60 mph and travels one mile so the equation can be written as 60mph = 1/t
Rearrange to get t = 1/60
1/60 of an hour is 1 minute.
The time it took for the total journey is 1 + 2 = 3 minutes
Writing 3 minutes as a fraction of an hour:
3/60 = 1/20
So using the s = d/t formula to calculate the average speed the formula can be written as (the speed is unknown, time is 1/20 and the distance is 2 miles):
Speed = 2/(1/20) = 2x20/1 = 40
Therefore the average speed of that car is 40 mph.
