Answer:

  2 11/28

Step-by-step explanation:

  6 1/7 = 3 3/4 + p

  p = 6 1/7 - 3 3/4 = 5 32/28 - 3 21/28 = (5 -3) +(32-21)/28

  p = 2 11/28

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

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:

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

Answer: 4 paddles

Step-by-step explanation:

Mr. Jones buys the paddle for $35 and sells at 180% of the purchase price:

= 35 * 180/100

= $63

For the number of paddle sales to be at least $250, he should sell:

= 250/63

= 3.97

= 4 paddles

Answer:

UGHH SOMONE ANWER MY QUESTIONSS

Step-by-step explanation:

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

Answer:

Step-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).

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.

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:

13120(16)^t

Answer:

We conclude that the slope between (s, t) and (u, v):

Step-by-step explanation:

We can find the slope between two points (x₁, y₁) and (x₂, y₂) using the formula

slope =  [y₂ - y₁] / [x₂ - x₁]

In our case, the two points are

(x₁, y₁) = (s, t)

(x₂, y₂) = (u, v)

Thus, the slope between (s, t) and (u, v)

slope = [v - t] / [u - s]

Therefore, we conclude that the slope between (s, t) and (u, v):
