Answer:
13/15 of 1 mile, or 0.86666 miles
Step-by-step explanation:
If you are working with fractions, you can take the 2 3/5 miles of beach and convert that to 13/5 (10/5 = 2, then add the 3/5 = 10/5+3/5 = 13/5). Once converted, you can find out how much of that number allows pets by dividing that number by 3, or multiplying the result by 1/3.
13/5 * 1/3 = 13/15.
Another way to do this is to convert the original miles (2 3/5) to a decimal, which gives you 2.6 miles. Then take the 2.6 miles and again, either divide by 3 or multiply by 1/3 (which is basically the same thing). 2.6 ÷ 3 = 0.86666
Hope this helps!

cloud is a vegetable grower, has 8 4/15 plots of pechay, 5 1/3 plots of eggplants and 5 2/5 of okra . how many plots of vetable do cloud has?
Answer:
The total plots of vegetable cloud will have: 19
Step-by-step explanation:
As the cloud has:
[tex]8\frac{4}{15}[/tex] plots of pechay[tex]5\frac{1}{3}[/tex] plots of eggplants[tex]5\frac{2}{5}[/tex] plots of okaraSo, the total plots of vegetable cloud will have:
[tex]8\frac{4}{15}+5\frac{1}{3}+5\frac{2}{5}[/tex]
[tex]=\frac{124}{15}+\frac{16}{3}+\frac{27}{5}[/tex]
[tex]=\frac{124}{15}+\frac{80}{15}+\frac{81}{15}[/tex]
[tex]=\frac{124+80+81}{15}[/tex]
[tex]=19[/tex]
Therefore, the total plots of vegetable cloud will have: 19

Answer:
150 degrees
Step-by-step explanation:
(Sorry, I know you don't want one but I posted this and then started editing it so hopefully you saw the answer already and I'm not delaying you or anything)
The interior of a quadrilateral always adds up to 360 degrees. y+80 = 180 degrees since they're on a straight line.
We have 3 angles: y = 100, 50, and 60.
360 - (100+50+60)
= 360 - 210
= 150

Answer:
C . The answer can be simplified but its not on here for some reason.
Step-by-step explanation:
6 2/6 x 1 1/2
(6 x 6) + 2 = 38/6
(1 x 2) + 1 = 3/2
38/6 x 3/2 = 114/12
114 ÷ 12 = 9 6/12.
9 6/12 = 9 3/6 = 9 1/2.
C
Again it can be simplified buts it not on here for some reason.

A 90% confidence interval for the mean height of a population is This result is based on a sample of size 169. Construct a 99%confidence interval.
This question is incomplete, the complete question is;
A 90% confidence interval for the mean height of a population is 65.7 < μ < 67.3
This result is based on a sample of size 169.
Construct a 99%confidence interval.
Answer: at 99%, confidence interval is [ 65.2, 67.8 ]
Step-by-step explanation:
Given that;
confidence level = 90%
∝ = 1 - 90% = 1 - 0.9 = 0.1
the mean height of a population is 65.7 < μ < 67.3
so
x" - t_∝/2, n-1{standard Error] = 65.7 ----let this be equation 1
x" + t_∝/2, n-1{standard Error] = 67.3 -----let this be equation 2
where t∝/2, n-1 = t_0.1/2, 169 - 1 = t_0.05, 168 = 1.654 (t table)
now we add equation one and equation two
2x" = 65.7 + 67.3 = 133
x" = 66.5
next we subtract equation one from equation two
(x" + t_∝/2, n-1{standard Error]) - (x" - t_∝/2, n-1{standard Error])
= 67.3 - 65.7 = 1.6
so
2 × t_∝/2,n-1 × standard Error = 1.6
standard Error = 1.6 / (2 × t_∝/2,n-1)
we substitute
Standard Error = 1.6 / ( 2 × 1.654 ) = 1.6 / 3.308 = 0.48367
Now 99% confidence interval for μ is given as;
∝ = 1 - 0.99 = 0.01
x" ± t_∝/2, n-1{standard Error]
(x" ± t_0.01/2, 169-1 [standard Error])
where t_0.005, 168 = 2.6054 (t table)
now for Lower Bound: (x" - t_0.005, 168 [standard Error])
Lower Bound : ( 66.5 - (2.6054 × 0.48367))
= 66.5 - 1.26015 = 65.2398
Upper Bound : ( 66.5 + (2.6054 × 0.48367))
= 66.5 + 1.26015 = 67.7602
Therefore at 99%, confidence interval is [ 65.2, 67.8 ]

How many exact tenths are in 21.34. Why is it not 3?
Answer:
213.4 tenths

In the 2nd week of the year Carrie had $700 in her savings account. At 5 weeks she had $325. What is the equation that represents this situation?
Answer:
y = 125x + 75
Step-by-step explanation:
Let x represents the week and
Let y represent the balance
When x = 2, y = 325.
This means
(x1,y1) = (2,325)
When x = 5, y = 700
This means
(x2,y2) = (5,700)
Required
Determine the equation
First, we need to solve for m, the slope
m = ∆y/∆x
i.e.
m = (y2 - y1)/(x2 - x1)
Substitute values for x and y
m = (700 - 325)/(5 - 2)
m = 375/3
m = 125
Next, we calculate the equation in slope intercept form using
y - y1 = m(x - x1)
Substitute values for m, x1 and y1
y - 325 = 125(x - 2)
y - 325 = 125x - 250
Collect like terms
y = 125x - 250 + 325
y = 125x + 75
Hence, the equation is:
y = 125x + 75
Answer: x=-125+950
Step-by-step explanation:
The value went from 700 to 325 in 3 weeks
700-325= 375 /3 =125
0=950
1=825
2=700
3=575
4=450
5=325
Find the antiderivative of f (x) = 10x4 + 12.5.
Answer:
The anti-derivative of f(x) will be:
[tex]\int \:10x^4+12.5dx=2x^5+12.5x+C[/tex]
Step-by-step explanation:
Given the function
[tex]\:f\left(x\right)=10x^4\:+\:12.5[/tex]
Taking the anti-derivative of f(x)
[tex]\int \left(10x^4\:+\:12.5\right)\:dx\:[/tex]
[tex]\mathrm{Apply\:the\:Sum\:Rule}:\quad \int f\left(x\right)\pm g\left(x\right)dx=\int f\left(x\right)dx\pm \int g\left(x\right)dx[/tex]
[tex]\int \left(10x^4\:+\:12.5\right)\:dx\:=\int \:10x^4dx+\int \:12.5dx[/tex]
Solving
[tex]\int 10x^4dx[/tex]
[tex]\mathrm{Take\:the\:constant\:out}:\quad \int a\cdot f\left(x\right)dx=a\cdot \int f\left(x\right)dx[/tex]
[tex]=10\cdot \int \:x^4dx[/tex]
[tex]\mathrm{Apply\:the\:Power\:Rule}:\quad \int x^adx=\frac{x^{a+1}}{a+1},\:\quad \:a\ne -1[/tex]
[tex]=2x^5[/tex]
similarly,
[tex]\int 12.5dx[/tex]
[tex]\mathrm{Integral\:of\:a\:constant}:\quad \int adx=ax[/tex]
[tex]=12.5x[/tex]
so substituting these values
[tex]\int \left(10x^4\:+\:12.5\right)\:dx\:=\int \:10x^4dx+\int \:12.5dx[/tex]
[tex]=2x^5+12.5x[/tex]
[tex]=2x^5+12.5x+C[/tex] ∵ Add constant to the solution
Therefore, the anti-derivative of f(x) will be:
[tex]\int \:10x^4+12.5dx=2x^5+12.5x+C[/tex]
