850 students so those with no participation would be 12% of 850, which is also 0.12*850. Only one sport would be 0.42*850. Two sports would be 0.28*850. Three or more sports would be 0.18*850.
No participation: 102 students
Only one sport: 357 students
Two Sports: 238 students
Three of more sports: 153 students
Answer:
No Participation: 102 students
Only One Sport: 357 students
Two Sports: 238 students
Three or More Sports: 153 students
Step-by-step explanation:
The percentages represent parts of the total.
To calculate the number of students, we would need to take a percentage of the total.
So for the No Participation group, we would take 12% of 850. "Of" indicates that we would multiply the terms together.
To multiply a %, we first need to convert it to a decimal by moving the decimal point to the left two times.
The No Participation group would then be 0.12 × 850 which equals 102.
The 1 sport group would be 0.42 × 850 = 357
The 2 sport group would be 0.28 × 850 = 238
And the 3+ sport group would be 0.18 × 850 = 153

The foot of the ladder is 1.5m from the foot of the wall.
How far up the wall does the ladder reach?
any help would be appreciated
Answers
Answer:
b=8.9m
Step-by-step explanation:
you would need to use Pythagoras theorem
a²+b²=c²
as we know c=9m and a=1.5m we need to find b so you would have to rearrange the equation
b²=c²-a²
b²=9²-1.5²
b²=81-2.25
b²=78.75
b=√78.75
b= 8.9m (1DP)
Jasmin's dog weighs 58 pounds. Her vet told her that a healthy weight for her dog would be less than or equal to 40 pounds. Jasmin's dog can lose an average of 1.5 pounds every week. Write the solution to an inequality that describes all possible number of weeks [Math Processing Error] x for which her dog can be at a healthy weight.
Answers
You always have to mutiply the week number by 1.5 to see how many pounds the dog has lost. For example, week 1 = 1*1.5 = 1.5 pounds lost in the first week. You can also divide the pound by 1.5 to get the week number which is what I will be doing. 58 - 40 = 18 pounds minimum to be healthy. 18/1.5 = 12. That means if Jasmin's dog is dieting properly for 12 weeks, she will be healty.
If she diets more, she will still be healty because you need 40 or less pounds to be healty.
This sentance is extra but why are 0 pounds healthy?

find the area of the circles
Answers
Answer:
7) 28.27 cm²
8) 63.62 ft²
9) 113.10 in²
Step-by-step explanation:
You want the areas of the circles with the given diameters.
AreaThe area formula for a circle is usually written in terms of the radius of the circle. Since the diameter is given, we can rewrite the formula to make use of the diameter:
A = πr²
A = π(d/2)² . . . . . . . use d/2 for r
A = (π/4)d² . . . . . . . collect constants
Application7) Diameter = 6 cm; Area = (π/4)(6 cm)² = 9π cm² ≈ 28.27 cm²
8) Diameter = 9 ft; Area = (π/4)(9 ft)² = 20.25π ft² ≈ 63.62 ft²
9) Diameter = 12 in; Area = (π/4)(12 in)² = 36π in² ≈ 113.10 in²

What is the slope of the line on the graph ? I’ll give you a like for answer plus I suck at math also this is k12 answer
Answers
Answer:
m= [tex]-\frac{1}{3}[/tex]
Explanation:
Formula is Y=mx+b
m equals the slope (rise/run each point).
x stays for an ongoing function.
b is the y intersect(You'll see that the line crossed +4 on the vertical line).
Looking at the line from left to right, it starts from the top to the bottom instead of button to top. If this slope goes down, it is negative.

The mean and median of the data(weight of trash in pounds for given years) given in the table is evaluated as:
Mean ≈ 4.1 poundsMedian = 4.44 How to find mean and median of a data?Mean is the ratio of sum of the observations to the total number of observations.
Median is such a number for the arranged data set(ascending or descending order) such that to its left and to its right belong same number of observations.
For the given case, the data observations are:
3.25, 3.25, 3.66, 3.83, 4.57, 4.52, 4.74, 4.69, 4.44 (they are measurement of pounds of trash for specified years(in the problem statement) )
They are total 9 observations.
Their sum is 36.95 approx.
Thus, mean of this data set = sum/number of observations [tex]\approx 36.95/9 \approx 4.1[/tex]
Arranging the data in ascending order gives
3.25, 3.25, 3.66, 3.83, 4.44, 4.52, 4.57, 4.69, 4.74
There are 9 values, therefore, the fifth value would be median as to its left and to its right will lie four-four observations.
Thus, median of the data set = 4.44

Answer:
9) 5.8
10) 27.9
11) 37.1
12) 16.8
Step-by-step explanation:
For this you need to know SOH (sine = opposite/adj) CAH (cos = adj/hypo) and TOA (tan = opp/adj).
For 9, you have one side 15 and one angle 21 degrees. We can see that relative to the 21 degrees the side lengths, x and 15, are the Opposite and the Adjacent. So we label them "x=O" and "15=A". This means we have Tangent(21) = Opposite "x" /Adjacent "15"
We then evaluate tan21=x/15.
1) To get rid of the fraction multiply 15 on both sides to get 15*tan21=x.
2) Use a calculator to get the answer 5.8 (5.7579..)
For 10, it is the same process but with cosine. You have one side 19 and one angle 47 degrees. We can see that relative to the 21 degrees the side lengths, x and 19, are the Hypotenuse and the Adjacent. So we label them "x=H" and "19=A". This means we have Cosine(47) = Adjacent "19" / Hypotenuse "x"
We then evaluate cos47=19/x.
1) To get rid of the fraction multiply x on both sides to get x*cos47=19.
2) Divide by cos47 on both sides to isolate x. This will be x=47/cos21
3) Use a calculator to get the answer 27.9 (27.8593...)
For 11, refer to how I did question 9 on how it's tan68 = 15/x.
Then refer to question 10 on what to do if x is the denominator (isolate the x).
You should end up with x=15/tan68 which is 37.1 (37.1263...)
Finally for 12, it's the same but for sine (sin=opp/hyp).
You should get that the opp=15 and hypo=x.
That means sin63=15/x which is then x=15/sin63
Answer is 16.8 (16.834...)

Which statement BEST describes the validity of these solutions? A. Neither solution is valid since time values cannot be squared. B. The solution t = – 2 is the only solution since 5 seconds is an unreasonable amount of time for the object to reach a height of 50 feet. C. The solution t = 5 is the only valid solution to this system since time cannot be negative. D. Both are valid solutions to this system since both values make the equation h=−16t^2+ 48t + 210 true.
Answers
Given:
The height h of an object after t seconds is
[tex]h=-16t^2+48t+210[/tex]
The height of a neighboring 50-foot tall building is modeled by the equation h=50.
The time (t) when the object will be at the same height as the building is found to be t = –2 and t = 5.
To find:
The statement which describes the validity of these solutions.
Solution:
We have,
[tex]h=-16t^2+48t+210[/tex]
Here, t is the time in seconds.
For t=-2,
[tex]h=-16(2)^2+48(-2)+210[/tex]
[tex]h=-64-96+210[/tex]
[tex]h=50[/tex]
For t=5,
[tex]h=-16(5)^2+48(5)+210[/tex]
[tex]h=-400+240+210[/tex]
[tex]h=50[/tex]
So, the value of h is 50 at t=-2 and t=5.
We know that time is always positive so it cannot be negative value. It means t=-2 is not possible.
The solution t = 5 is the only valid solution to this system since time cannot be negative.
Therefore, the correct option is C.

Then the ratio is ...

The time needed to reach the amount of $21000 will be 36.5 years.
What will be the time to reach the amount $21000?It is given that
Principle = $8600
Rate = 3.95%
Total amount = $21000
So the total interest will be = Amount -principle = 21000-8600=$12400
So by using the formula
[tex]SI = \dfrac{P\times R\times T}{100}[/tex]
Here p = principle
R= Rate of interest
T= time
SI= interest amount
Now putting the values
[tex]12400= \dfrac{8600\times3.95\times T\time}{100}[/tex]

x = 36*4
x = ₹ 144
