There is four 1/4's per mile.
This means you run 1 mile in 3 x 4 = 12 minutes.
Multiple minutes per mile by total miles:
12 minutes per mile x 26.2 miles = 314.4 minutes.
1 hour = 60 minutes:
Divide total minutes by 60 to get hours:
314.4 minutes / 60 minutes per hour = 5.24 hours.
Multiply the decimal part of the hour by 60 to get the minutes:
0.24 x 60 = 14.4 minutes = 14 minutes and 24 seconds.
Total time = 5 hours, 14 minutes and 24 seconds.

x^5 + ax^3 + bx^2 - 3 = (x^2 - 1)Q(x) - x - 2
find the value of a and b?
9514 1404 393
Answer:
a = -2b = 1Step-by-step explanation:
Subtracting the remainder from the original polynomial gives a polynomial that has (x^2 -1) as a factor. Dividing, we find the quotient and remainder to be ...
(x^5 +ax^3 +bx^2 +x -1)/(x^2 -1) = (x^3 +(1+a)x +b) remainder (2+a)x +(b -1)
Since we want the remainder to be zero, we require ...
2+a = 0 ⇒ a = -2
b -1 = 0 ⇒ b = 1
_____
The attachment shows the division as given in the problem statement (with the given remainder expression).
Can someone help solve this
Answer:
336 cubic cm
Step-by-step explanation:
Volume of cone + (Volume of Sphere/2)
V (cone) = (π[tex]r^{2}[/tex]h)/3
= π[tex]4^{2}[/tex](12) ÷ 3
= 64π ≈ 201 cm
V (sphere) = 4/3π[tex]r^{3}[/tex]/2
= [4/3π(4^3)] ÷ 2
= (256π/3) ÷ 2
≈ 43π ≈ 135

Explain the importance of putting your data set in order from least to greatest
Answer:
The mean may not be a fair representation of the date
Step-by-step explain the average is easily influenced by outliers (very small or large values in the data set that are not typical). The median is another way to measure the center of a numerical data set. ... Thus, the median is truly the middle of the data set.

Solve the problem By using area models Problem: shereen 119 books into 7 even piles .How many books did shereen put in each pile ?
Answer:
the 17 books should be put in each pile
Step-by-step explanation:
The computation of the number of books in each pile is shown below:
Given that
There are 119 books
And there are 7 piles
So, the number of books in each pile is
= 119 books ÷ 7 piles
= 17 books
Hence, the 17 books should be put in each pile
So the same is to be conisdered and relevant too

She uses 13 of her supply of sunflower seeds to make a salted snack mix and 29 of her supply to make an unsalted snack mix. If Cecile uses 10 pounds of sunflower seeds, how many pounds of seeds are in her supply?
Answer:
18 pounds
Step-by-step explanation:
Here is the full question :
Cecile packages snack mix at a health food store.
She uses 1/3 of her supply of sunflower seeds to make a salted snack mix and 2/9 of her supply to make an unsalted snack mix. If Cecile uses 10 pounds of sunflower seeds, how many pounds of seeds are in her supply?
Let x = Cecile's supply
1/3 of x = 1/3x
2/9 of x = 2/9x
1/3x + 2/9x = 10
adding the fraction together gives 5/9
5/9 x = 10
solve for x = 18 pounds

Step-by-step explanation:
The number of views on a viral video can be modeled by the function Q(t)=410(5)^{2t}.Q(t)=410(5) 2t . Write an equivalent function of the form Q(t)=ab^t.Q(t)=ab t .
Answer: Q(t) = 410*(5)^(2t) = 410*(5^2)^t = 410*(25)^t
Step-by-step explanation:
We start with the equation:
Q(t) = 410*(5)^(2t)
And we want to rewrite this in the form:
Q(t) = a*b^t
To do this, we need to use the property:
(a^x)^y = a^(x*y)
Using this, we can rewrite:
Q(t) = 410*(5)^(2t) = 410*(5^2)^t = 410*(25)^t
And this is the form that we wanted:
Answer:

The amount of time T (in years) it will take for a population of a certain species to grow from 3500 to a can be modeled by the function Y(a)=log _(5) (a/3500)^1/0.03. Which function is equivalent?
Answer:
Option C is correct
Step-by-step explanation:
Here, we want to find which of the equations in the option is same as that in the question
The rule to use is that;
Loga B^y
= ylogaB
And also:
loga(X/Y) = logaX-logaY
Now, we start by applying these equations;
T(a) = log5 (a/3500)^1/0.03
T(a) = 1/0.03log5(a/3500)
T(a) = 1/0.03log5a - 1/0.03log53500
This makes the third option correct

Answer: 4 paddles
Step-by-step explanation:
