Answer:
time=distance/speed
time=500/45
time=11.11 sec
Answer:
11 1/9 seconds = time
Step-by-step explanation:
We know that
Distance = rate * time
500 m = 45 m/s * time
Divide each side by 45
500/45 = time
11 1/9 seconds = time

The area of a rectangle is 52 inches if the length is two times the width find the dimensions of the rectangle round off your answer to the nearest hundredth
Answer:
about 5.10 by 10.20 inches
Step-by-step explanation:
You can substitute the width for "x"
This would make the length 2x as it is two times the width
Area in a rectangle is Length times Width, so in this case it would be 2x * x
It gives you the area as 52 inches, so you can substitute this in the equation making it 52 = 2x^2
divide by two on both sides: 26 = x^2
take the square root of both sides, and x is 5.0999
Now to find the length, just double it, which rounds out to 10.20
5.0999 rounds to the hundredth as 5.10
so for dimensions you have 5.10 by 10.20

Answer:
UW = 67
Step-by-step explanation:
In order to find UW, we need to add UV and VW because them together makes the entire line, also known in this problem as UW. This is our equation:
UV + UV = UW
This is the equation if you plug the numbers:
19 + 4x - 20 = 6x - 35
Combine like terms to make it easier to do the math:
4x - 1 = 6x - 35
Then do the math:
(4x - 4x) -1 = (6x - 4x) - 35
-1 = 2x - 35
(-1 + 35) = 2x (- 35 + 35)
34 = 2x
34/2 = 2x/2
x = 17
Then you plug in x for the UW expression:
6x - 35
6(17) - 35
102 - 35
67
UW = 67

x/2 = 16 Multiply both sides by 2
2*x/2 = 16*2
x = 32
You are at about the second stage of solving equations. So far what you should know is that you should add or subtract before doing multiplication or division.
Take a much simpler question
x - 8 = 10 What do you do here? You can't multiply or divide. So add
+8 8
x = 18
Now try what you have
2x - 5 = 11 Add before multiplication or division
5 5
2x = 16 Divide by 2
2x/2 = 16/2
x = 8
union and intersection of sets
Answer:
The union of two sets contains all the elements contained in either set (or both sets). The union is notated A ⋃ B. The intersection of two sets contains only the elements that are in both sets. The intersection is notated A ⋂ B.
Answer:
UnionThe union of a set A with a B is the set of elements that are in either set A or B. The union is denoted as A∪B. For example, if A is the set {♢,♡,♣,♠} and B is the set {△,♡,♠}, then A∪B={♢,♡,♣,♠,△}.
IntersectionIntersection of two given sets is the largest set which contains all the elements that are common to both the sets. To find the intersection of two given sets A and B is a set which consists of all the elements which are common to both A and B. The symbol for denoting intersection of sets is '∩'.

Point O is the centroid of triangle ABC. If OD=3x -2 and OC= 5x, find x.
At centroid medians bisect each other in the ratio 2:1
[tex]\\ \sf\longmapsto OC=2(OD)[/tex]
[tex]\\ \sf\longmapsto 2(3x-2)=5x[/tex]
[tex]\\ \sf\longmapsto 6x-4=5x[/tex]
[tex]\\ \sf\longmapsto 6x-5x=4[/tex]
[tex]\\ \sf\longmapsto x=4[/tex]
The value of x is 4, when we are given O is the centroid of the triangle ABC, OD = 3x - 2, and OC = 5x.
What is the centroid of a triangle?The center of the thing is represented by its centroid. The centroid of a triangle is the location where the triangle's three medians connect. The junction of all three medians is another definition for it. The median is a line that connects the middle of a side to the triangle's opposite vertex. The median is divided by the centroid of the triangle in a ratio of 2:1.
How to solve the question?In the question, we are given that O is the centroid of triangle ABC, and are asked to find the value of x, for which OD = 3x - 2, and OC = 5x.
We know that the median is divided by the centroid of the triangle in a ratio of 2:1.
Thus, the median CD is divided by the ratio of 2:1 as,
2/1 = OC/OD,
or, 2/1 = (5x)/(3x - 2),
or, 2(3x - 2) = 1(5x) {Cross-multiplying},
or, 6x - 4 = 5x,
or, 6x - 5x = 4,
or, x = 4.
Thus, the value of x is 4, when we are given O is the centroid of the triangle ABC, OD = 3x - 2, and OC = 5x.

According to the graph of the rational function
y= 4/x^2-4
which of the following statements is/are true?
I. The function is even
II. The function is increasing for all values in the domain
III. There is a horizontal asymptote along the x-axis,
I only
I and II only
I and Ill only
I, II and III
9514 1404 393
Answer:
I and III only
Step-by-step explanation:
The graph is symmetrical about the y-axis, so is an even function.
The function is decreasing in the 1st quadrant, so is not increasing everywhere.
The values of the function approach y=0 for extreme values of x, so the graph shows that as a horizontal asymptote.

What is the value of (x – 3) if – 5(3x – 9) = -15?
The value of the required expression (x- 3 ) using the given equation -5(3x - 9) = -15 is equal to 1.
Let's solve for the value of "x" in the given equation:
-5(3x - 9) = -15
First, distribute the -5 on the left side of the equation:
-15x + 45 = -15
Now, subtract 45 from both sides to isolate the term with "x":
-15x = -60
Divide both sides by -15 to solve for "x":
x = 4
Now that we have the value of "x," we can find the value of (x - 3):
x - 3
= 4 - 3
= 1
Therefore, the value of (x - 3) is 1.

A Shape Question 5 options: 13 yd.² 314 yd.² 251 yd.² 503 yd.²
Answer:
What is question? surface area of upright part of cylinder is approx 314 sq yd. Surface area of entire cylinder is approx 471 sq yd, which isn't a choice.
Step-by-step explanation:
Assuming you're looking for surface area of cylinder (since answers are in sq units), you would need to find the area of the top and bottom circles, and the rectangle made by flattening out the upright part of cylinder.
Area of a circle is πr^2 so area of bottom is 25π and of both circles is 50π which equals approx 157.08 sq yd.
The rectangle formed from the upright part would have a width of 10 yds and a length equal to circumference of the circle. Since C = πd, C is approx 31.4yd. A = l x w so A = 31.4 x 10 or approx 314 sq yd.
