a circular pool has a circumference of 28 feet what is the radius of the pool in feet
Answer:
The formula for circumference of s circle is pi x diameter.
If the circumference is 28 we can divide it by pi to get the Diameter.
28/ pi = 8.9126768131461388030574907488608042739297 rounded to 8.91 (2dp)
The radius is half of the diameter, so this means 8.91 / 2 = 4.46 ft (rounded to 2dp)

If two equations are 3x + 2y = 14; 5x + 3y = 12, then the value of
5x – y is
Answer:
-124
Step-by-step explanation:
3x + 2y = 14 (×3) → 9x + 6y = 42
- → x = -18
5x + 3y = 12 (×2) → 10x + 6y = 24
3(-18) + 2y = 14
-54 + 2y = 14 → 2y = 14 + 54 = 68 → y = 68/2 = 34
5x - y = 5(-18) - 34 = -90 - 34 = -124

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...)
in the given image 01 equals 02 and the angles are measured in radians which of these are true
A radian is denoted by rad and it's the standard unit that is used for the measurement of angles.
What is a radian?Your information is incomplete. Therefore, an overview of radians will be given. Radian is the standard unit for angular measurement.
A radian is a unit of measure for angles which is based on the radius of circles. The formula used for radians is simply put as:
= (Degrees × π) / 180°
For example 60° will be:
= (60° × π) / 180°
= π/3
Therefore, 60° converted to radians is π/3.

A 2-column table with 9 rows. The first column is labeled year with entries 1970, 1975, 1980, 1985, 1990, 1995, 2000, 2005, 2010. The second column is labeled pounds of trash with entries 3. 25, 3. 25, 3. 66, 3. 83, 4. 57, 4. 52, 4. 74, 4. 69, 4. 44. The table shows the average number of pounds of trash generated per person per day in the United States from 1970 to 2010. Use the statistics calculator to calculate the mean and median. Round the answers to the nearest hundredth. Median = Mean =.
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
Therefore, the mean and median of the data(weight of trash in pounds for given years) given in the table is evaluated as:

Jared and maila will usually both run 3 miles each time they go running .This month,jared ran an additional 21 miles. Which answer choice shows an expression that represent the total distance jared and malia ran this month if j=the number of time that jared ran and m=the number of times that malia ran?
Answer:
Total = m + j
= 3 + m + 21
Step-by-step explanation:
Mails = 3 miles
Jared = 3 miles + 21 miles
j = m + 21
m = 3
Total = m + j
= 3 + m + 21
Where,
m = 3
Total = 3 + m + 21
= 3 + 3 + 21

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.
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?

Xavier opened a savings account with a deposit of $12,000. The account earned simple interest. He did not make any additional deposits or withdrawals. At the end of 3 years, the account balance was $12,324. What is the annual interest rate on this account? 0. 9% 1. 8% 2. 7% 3. 6%.
The annual interest rate on the saving account of Xavier which is earned simple interest is 9%.
What is simple interest?Simple interest is the amount charged on the principal amount with a fixed rate of interest for a time period. Simple interest calculated only on the principal amount.
The formula for the simple interest can be given as,
[tex]I=\dfrac{PRT}{100}[/tex]
Here, (I) is the interest amount on the principal amount of (P) with the rate of (r) in the time period of (t).
Xavier opened a savings account with a deposit of $12,000. At the end of 3 years, the account balance was $12,324.
The principal amount is $12000 and the total amount is $12324. Thus, the interest earned by the Xavier is,

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

find the area of the circles
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

Average rate of change = -4
Step-by-step explanation:
Given:
f(x) = x² + 7x + 10
-8 ≤ x ≤ -3 or [-8, -3] in interval notation
Average rate of change of the function can be solved using the formula:
[tex]\mathrm{Average\:rate\:of\:change} = \dfrac{ f \left( b \right) -f \left( a \right) }{ b-a }[/tex]
[tex]\mathrm{Average\:rate\:of\:change} = \dfrac{ f \left( -3 \right) -f \left( -8 \right) }{ -3 - (-8) }[/tex]
[tex]\mathrm{Average\:rate\:of\:change} = \dfrac{ f \left( -3 \right) -f \left( -8 \right) }{ -3 + 8 }[/tex]
[tex]\mathrm{Average\:rate\:of\:change} = \dfrac{ f \left( -3 \right) -f \left( -8 \right) }{ 5 }[/tex]
Substitute x = -3 to the given function for f(-3) and x = -8 for f(-8)
[tex]\mathrm{Average\:rate\:of\:change} = \dfrac{ f \left( -3 \right) -f \left( -8 \right) }{ 5 }[/tex][tex]\mathrm{Average\:rate\:of\:change} = \dfrac{ { \left[( -3 \right) }^{ 2 } +7 \left( -3 \right) +10]- { \left[( -8 \right) }^{ 2 } +7 \left( -8 \right) +10] }{ 5 }[/tex]

What is 5 to the power of 3 divided by 5 to the power of 6?
Answer:
1/5³ = 1/125 = 5⁻³
Step-by-step explanation:
It can be useful to remember that an exponent signifies repeated multiplication.
5^3 = 5×5×5
5^6 = 5×5×5×5×5×5
Then the ratio is ...
[tex]\dfrac{5^3}{5^6}=\dfrac{5\times5\times5}{5\times5\times5\times5\times5\times5}=\dfrac{1}{5\times5\times5}=\boxed{\dfrac{1}{125}}[/tex]
__
If you want to leave this in terms of exponents, you can see that factors in the denominator cancel (subtract from) those in the numerator. That is ...
[tex]\dfrac{5^3}{5^6}=\dfrac{5^{3-3}}{5^{6-3}}=\dfrac{5^0}{5^3}=\boxed{\dfrac{1}{5^3}}[/tex]
The same sort of exponent arithmetic works to leave a numerator value with a negative exponent:
[tex]\dfrac{5^3}{5^6}=\dfrac{5^{3-6}}{5^{6-6}}=\dfrac{5^{-3}}{5^0}=\dfrac{5^{-3}}{1}=\boxed{5^{-3}}[/tex]
