Answer:
The number of cups of seeds that Sarah put in each bird feeder each day is:
= 4/7 or 0.57 cups.
Step-by-step explanation:
a) Data and Calculations:
Number of cups of seeds = 12 cups
Number of bird feeders = 3
Therefore, each bird feeder will get 12/3 = 4 cups per week
In a week, there are 7 days.
This implies that each bird feeder will get 4/7 cups
This is equivalent to 0.57 cups for each bird feeder per day.
b) Sarah will be putting 4/7 cups of seeds in each bird feeder. When 4/7 is multiplied by 3 *7, we get a total of 12 cups, which represent the total number of cups of seed given initially to Sarah.
Answer:
The number of cups of seeds that Sarah put in each bird feeder each day is: = 4/7 or 0.57 cups.

At the store for every 2 movies sold there 8 books sold. What is the radio of books sold to movies sold?
Answer:
The ratio of books sold to movies sold at the store is 4:1.
Step-by-step explanation:
Given that:
Number of movies sold at the store = 2 movies
Number of books sold at the store = 8 books
Ratio of books sold to movies sold at the store is
Books sold : Movies sold
8 : 2
[tex]\frac{8}{2}:\frac{2}{2}[/tex]
4 : 1
Hence,
The ratio of books sold to movies sold at the store is 4:1.
tan A = 1/5 and tan B = 1/4
Find tan 2 (A-B)
Given:
[tex]\tan A=\dfrac{1}{5}[/tex]
[tex]\tan B=\dfrac{1}{4}[/tex]
To find:
The value of [tex]\tan^2(A-B)[/tex].
Solution:
We know that,
[tex]\tan (A-B)=\dfrac{\tan A-\tan B}{1+\tan A\tan B}[/tex]
Putting the given values, we get
[tex]\tan (A-B)=\dfrac{\dfrac{1}{5}-\dfrac{1}{4}}{1+\dfrac{1}{5}\cdot \dfrac{1}{4}}[/tex]
[tex]\tan (A-B)=\dfrac{\dfrac{4-5}{20}}{1+\dfrac{1}{20}}[/tex]
[tex]\tan (A-B)=\dfrac{\dfrac{-1}{20}}{\dfrac{20+1}{20}}[/tex]
[tex]\tan (A-B)=\dfrac{-1}{21}[/tex]
Taking square on both sides, we get
[tex]\tan^2 (A-B)=\left( \dfrac{-1}{21}\right)^2[/tex]
[tex]\tan^2 (A-B)=\dfrac{1}{441}[/tex]
Therefore, the value of [tex]\tan^2(A-B)[/tex] is [tex]\dfrac{1}{441}[/tex].

A line passes through the points (4,8) and (2,0). What is its equation in slope-intercept
form?
Answer:
The answer is y = 4x - 8.
Step-by-step explanation:
☆Remember: [tex]m = \frac{y_2 - y_1}{x_2 - x_1} [/tex]
☆Slope-intercept: [tex]y = mx + b[/tex]
---
☆We need to find the slope first. So just plug in according to the slope formula!
[tex]m = \frac{0 - 8}{2 - 4} = \frac{ - 8}{ - 2} = 4[/tex]
---
☆Now we need to find the y-intercept. We are going to plug in the slope and a set of coordinates to find the y-intercept.
[tex]y = mx + b \\ 8 = 4(4) + b \\ 8 = 16 + b \\ \frac{ - 16 = - 16 \: \: \: \: \: \: \: \: \: \: \: \: }{ - 8 = b \: \: \: \: \: \: \: \: \: \: \: \: \: \: } [/tex]

☆Now all we need to do is plug in and we are done!
[tex]y = 4x - 8[/tex]

Step-by-step explanation:
but i don't know for the 2nd
Answer:
2/3 is 266.666667% of 1/4
2/3 is 400% of 1/6
Step-by-step explanation:
You just need to divide the second number by the first:
2/3 ÷ 1/4 = 2/3 · 4 = 2 2/3 which, in a percentage, is 266.666667.
2/3 ÷ 1/6 = 2/3 · 6 = 4 and 4 as a percentage is 400%

A park is rectangular with a length of 1/2 miles. If the area of the park is 6/8 square miles, what is its width? Input your answer as a fraction.
giving 40 points! please help soon <33
Step-by-step explanation:
Area of Park = Length * Width
Therefore Width = Area / Length
= (6/8) / (1/2) = (6/8) * (2/1) = 3/2 miles.
Answer:Area of Park = Length * Width
Therefore Width = Area / Length
= (6/8) / (1/2) = (6/8) * (2/1) = 3/2 miles.

What is the result of adding these two equations?
-52 - 9y = 3
5.2 - 9y = -2
Answer:
5.7-18y=1
Step-by-step explanation:
52-9y=3
5.2-9y=-2
or,57.2-18y=1
Answer:
-18y = 46.8
Step-by-step explanation:
Adding Left hand side elements together as well as right hand side
Eq1 = equation 1
Eq2 = equation 2
LHS(left hand side of the equation)
RHS(right hand side of the equation)
LHS of Eq1 + LHS of Eq2 = RHS of Eq1 + RHS of Eq2
-52 -9y + 5.2 -9y = 3 - 2
=> -9y -9y - 52 + 5.2 = 1
=> -18y - 46.8 = 1
=> -18y - 46.8 = 0
=> -18y = 46.8

Please help, 5 (y + 2/5) = -13. Y=?
Answer:
y = -3
Step-by-step explanation:
5y + 10/5 = -13 (distribute 5)
5y + 2 = -13 (simplify fraction)
5y = -15 (subtract 2 from both sides)
y = = -3 (divide 5 from both sides)
Checked worked:
5 ([-3] +2/5)
-15 + 10/5
-15 + 2 = -13
y = -3

What are all values of x for which the function f defined by f(x)=x3+3x2−9x+7 is increasing ?
(A) −3
(B) −1
(C) x<−3 or x>1
(D) x<−1 or x>3
(E) All real numbers.
Answer:
C. [tex]x < -3[/tex] or [tex]x > 1[/tex].
Step-by-step explanation:
Let [tex]f(x) = x^{3}+3\cdot x^{2}-9\cdot x +7[/tex], the first derivate of the function is:
[tex]f'(x) = 3\cdot x^{2}+6\cdot x -9[/tex] (1)
By the Quadratic Formula, we determine the roots of this polynomial:
[tex]x_{1} = 1[/tex], [tex]x_{2} = -3[/tex]
And the factorized form of the polynomial is:
[tex](x-1)\cdot (x+3) > 0[/tex]
By law of Signs, the polynomial is increasing when [tex]x-1 > 0[/tex] and [tex]x +3 > 0[/tex] or [tex]x-1 < 0[/tex] and [tex]x+3 < 0[/tex], which means that:
[tex]x < -3[/tex] or [tex]x > 1[/tex]
Therefore, the right answer is C.
Answer:
The correct option is an option (c).
Given:
The given function is,
[tex]f(x)=x^{3}+3x^{2}-9x+7[/tex]
Computation:
The function is increasing when [tex]f'(x)>0[/tex].
Now, differentiating the given function with respect to [tex]x[/tex] up to first order we get,
[tex]f'(x)=3x^{2}+3(2x)-9(1)+0\\f'(x)=3x^{2}+6x-9\\=3(x^{2}+2x-3)\\=3(x(x+3)-1(x+3))\\=3(x+3)(x-1)[/tex]
So, the sign function is,
Therefore, [tex]f'(x)>0[/tex] when [tex]x\in (-\infty ,-3)\cup (1,\infty )[/tex]
So, [tex]f(x)[/tex] is increasing on [tex]x<-3[/tex] or [tex]x>1[/tex]
Hence, the correct option is an option (c).

How many solutions does -3x+15=3(5-x) have
Answer:
Infinite solutions
Step-by-step explanation:
So if simplified it would be
-3x+15=15-3x
Which is basically the same thing if arranged
15-3x=15-3x
-3x+15 can also be 15-3x still the same thing as adding 15 to -3x
So since these are equal anything could be used
like try 0
Both get 15
Try 1
Both get 12
