in a community center 15 bottles are evenly spaced 12 cm apart from each other in a row for a competition
what is the distance from the fourth bottle to the tenth bottle?
Answers
Answer:
72 cm
Step-by-step explanation:
Relative to the first bottle, there are n - 1 spaces between the first bottle and the nth bottle. Since, each bottle is placed relative to the first bottle.
Now, for the fourth bottle, that is, n = 4, there are 4 - 1 = 3 spaces between the first and fourth bottle.
Since each space is 12 cm, the distance between the first and fourth bottle is 12 cm × 3 = 36 cm.
Now, for the tenth bottle, that is, n = 10, there are 10 - 1 = 9 spaces between the first and fourth bottle.
Since each space is 12 cm, the distance between the first and fourth bottle is 12 cm × 9 = 108 cm.
So, the distance between the fourth bottle and tenth bottle is distance between tenth bottle to first bottle minus distance between fourth bottle to first bottle = 108 cm - 36 cm = 72 cm

Absolute value function:
|x| = x when x >= 0.|x| = -x when x < 0.Swim 3 feet under water => |-3|
Stand 20 feet above => |20|
Using the absolute value function,
we have |-3| = 3 and |20| = 20.
Since 3 is less than 20, |-3| < |20|. (C)

A florist was looking at her flower order. The ratio of roses to sunflowers was 4 to 9. When she was done, she realized there were 65 MORE sunflowers than roses. How many of each flower was there?
Answers
Answer:
[tex]52[/tex] roses and [tex]117[/tex] sunflowers
Step-by-step explanation:
Since the ratio of roses to sunflowers is [tex]4:9[/tex], we can represent how many there are of each as [tex]4x[/tex] and [tex]9x[/tex], respectively. We know that there are [tex]65[/tex] more sunflowers than roses, so we can set up the following equation to solve for [tex]x[/tex]:
[tex]4x+65=9x[/tex]
Solving for [tex]x[/tex], we get:
[tex]4x+65=9x[/tex]
[tex]4x+65-4x=9x-4x[/tex] (Subtract [tex]4x[/tex] from both sides of the equation to isolate [tex]x[/tex])
[tex]65=5x[/tex] (Simplify)
[tex]5x=65[/tex] (Symmetric Property of Equality)
[tex]\frac{5x}{5}=\frac{65}{5}[/tex] (Divide both sides of the equation by [tex]5[/tex] to get rid of [tex]x[/tex]'s coefficient)
[tex]x=13[/tex] (Simplify)
Therefore, since [tex]x=13[/tex], we know that there are [tex]4x=4*13=52[/tex] roses and [tex]9x=9*13=117[/tex] sunflowers. Hope this helps!

Step-by-step explanation:
Step one:
given data
The ratio of teachers to students on a field trip to New York City is 2 to 9.
That is the ratio is 2:9
We are told that there are 243 students
Required
We want to find the number of teachers
Step two:
Applying the part to part method we have
let the number of teachers be x
2/9= x/243
cross multiply we have
9x= 243*2
9x= 486
divide both sides by 9
x= 54
Hence there are 54 teachers

At the beginning of the day, the sum of the stocks in the Dow Jones was
$10,335.24. At the end of the day, the sum of the stocks in the Dow Jones
was $10,215.78. What was the rate of change of the Dow Jones on this
particular day?
Answers
Answer:
- 1.15585%
Step-by-step explanation:
Given that:
Sum of stock at beginning = $10,335.24
Sum of stock at the end of the day = $10,215.78
Rate of change of the Down Jones on that day :
The change in price on the day:
Ending - Beginning
10,215.78 - 10,335.24 = −119.46
The rate if change is thus ;
(Change in price / beginning stock price) * 100%
(-119.46 / 10,335.24) * 100%
-0.0115585 * 100%
- 1.15585%

Use the graph shown. State the number of real zeros of the function.
Answers
Answer:
Option B
Step-by-step explanation:
Zeros of a function are defined by the values of x at y = 0,
In other words, x-intercepts of a function graph are the zeros of the function.
Real zeros means graph should intersect or touch the x-axis.
If it is imaginary, the graph will have no x-intercept.
From the graph attached,
There are 3 points where the graph intersects the x-axis.
Therefore, the function will have 3 real zeros.
Option B is the answer.

At 10 AM horn and Tyler both started running toward each other from opposite ends of a 10 mile path along the river. On runs out a piece of 12 minutes per mile. Tyler is it a piece of 15 minutes from now. How far is home run after half an hour
Answers
Complete question :
At 10:00 am, Han and Tyler both started running toward each other from opposite ends of a 10 mile path along a river. Han runs at a pace of 12 minutes per mile Tyler runs at a pace of 15 minutes per mile how far does Han run after a half hour
Answer:
2.5 miles
Step-by-step explanation:
Given :
Distance between Horn and Tyler = 10 miles
Horn's pace = 12 minutes per mile
Tyler's pace = 15 minutes per mile
Horn's distance after half an hour :
Time = Half an hour = 30 minutes
Horn's speed = distance / time
Horn's speed = 1 mile / 12 minutes = 0.83333 miles per minute
Hence, Horn's distance after half an hour :
Distance = speed * time
Distance = 0.83333 miles per minute * 30 minutes
Distance = 2.5 miles
