Answer:
2 3/20 metres
Step-by-step explanation:
Area of the rug = Length × width
Given
Area = 7 1/6 metres = 43/6 m
Length = 3 1/3 metres = 10/3 m
Required
Width
From the formula
A = LW
W = A/L
Substitute the given values
W = 43/6÷10/3
W = 43/6×3/10
W = 43/2 ×1/10
W = 43/20
W = 2 3/20 m
Hence the width of the rug is 2 3/20 metres

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

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
The sum of two numbers is 81 the difference of the same two numbers is 33 write a system of equations to represent this situation then find the numbers
Answer:
48
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:
13120(16)^t

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

If Mr. Jones buys paddles for $35 instead of $50 and uses the same percent increase on price how many paddles most Mr. Jones sell for the total paddle sales before tax and to be at least $250 explain your answer
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

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).

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
