The ratio of teachers to students on a field trip to New York City is 2 to 9. If there are 243 students on the trip,
Answer:
54 teachers
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

Answer: 77
Step-by-step explanation:
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?
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

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?
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!
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?
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%
Answer: -1.2%
Step-by-step explanation:
Solving Quadratic Equations using the Square Root Property
[tex]x^2+7x+10=0[/tex]
but the teacher's guide says the answer is 17i
Answer:
[tex] x = -2 [/tex] or [tex] x = -5 [/tex]
Step-by-step explanation:
You need to complete the square before you can take the square root of both sides.
[tex] x^2 + 7x + 10 = 0 [/tex]
Subtract 10 from both sides.
[tex] x^2 + 7x = -10 [/tex]
To complete the square, you need to add the square of half of the x-term coefficient to both sides.
The x-term coefficient is 7. Half of that is 7/2. Square it to get 49/4. Now we add 49/4 to both sides of the equation.
[tex] x^2 + 7x + \dfrac{49}{4} = -10 + \dfrac{49}{4} [/tex]
[tex] (x + \dfrac{7}{2})^2 = -\dfrac{40}{4} + \dfrac{49}{4} [/tex]
[tex] (x + \dfrac{7}{2})^2 = \dfrac{9}{4} [/tex]
Now we use the square root property, if
[tex] x^2 = k [/tex], then
[tex] x = \pm \sqrt{k} [/tex]
[tex] x + \dfrac{7}{2} = \pm \sqrt{\dfrac{9}{4}} [/tex]
[tex] x + \dfrac{7}{2} = \pm \dfrac{3}{2} [/tex]
[tex] x + \dfrac{7}{2} = \dfrac{3}{2} [/tex] or [tex] x + \dfrac{7}{2} = -\dfrac{3}{2} [/tex]
[tex] x = -\dfrac{4}{2} [/tex] or [tex] x = -\dfrac{10}{2} [/tex]
[tex] x = -2 [/tex] or [tex] x = -5 [/tex]

two equations are shown in the picture please answer. giving brainiest
Answer:well for the first one I am not sure but I think that since four is over the x there should be 4/x + 3 so tragically I don’t know the answer but I think it should be 12 the x should be 12 because 4x3=12 so yea 12
Step-by-step explanation:and for the other one I don’t know but ima try it should be two because 2x2=4 and so y=1-2x2-4 that’s what I think sorry. I got it wrong and do good on your test for me please

Each Saturday, a gym holds one 45-miute Zumba class. The weekday Zumba classes last 30 minutes. The number of weekday classes varies. Last week, the Zumba classes totaled 165 minutes.
Write an equation that you can use to find the number of weekday Zumba classes held
a165c=30+45
b165=30+45c
c165=30c+45
How many weekday Zumba classes were held?
Answer:
C
Step-by-step explanation:
because it is asking to find the number of classes held during the weekday zumba class.
weekday class = 30 minutes
Saturday= 45 minutes
total = 165
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
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

Step-by-step explanation:
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)
Which of the following sets of numbers could not represent the three sides of a triangle?
{6,14,18}
{11,26,36}
{12,14,25}
{10,13,23}
Answer:
12,14,25 I think or A
Step-by-step explanation:
To enable a set of three numbers to represent three sides of a triangle, sum of smaller two numbers must be greater than the largest number. Hence, only C can represent a triangle
Which of the following is a linear function?
PLS HELP!!!!
y = x^3 + 1
5/6 x = y − 4
y = 8x^2
y = 1/5x
Answer:
y=3x+1
Step-by-step explanation:
You get all the steps you need in order to make a linear graph line. you see 3x is where the x intercept is going to be. you always need to see a number at the end of the equation with either +/- sign as in (+1).

b) Add the following equation:
x/3+4x/3
Answer:
5x/3
Step-by-step explanation:
Use the graph shown. State the number of real zeros of the function.
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.
