The healthy ice cream Jeremy is making has 30 bananas and requires 18 tablespoons of peanut butter.
What is a ratio?The ratio describes the amount of quantity in simplest form, a:b can be written as 'a/b' for convenience.
Given the healthy ice cream, Jeremy is making requires 5 bananas and 3 tablespoons of peanut butter.
From the given question itself, we can conclude that bananas and peanut butter are in direct proportion as the increase in one quantity will result in an increase of another quantity and we can write this in proportion and let the no. of tablespoons of peanut butter requires for 30 banans is x.
∴ 5 : 3 : : 30 : x.
Or
5/3 = 30/x.
5x = 90.
x = 18.
So, Jeremy needs 18 tablespoons of peanut butter for the 30 bananas he has.

What is the focus of the parabola? y=−1/4x^2 −2x − 2
Answer:
Step-by-step explanation:
This is a doozy. You have to know A LOT about parabolas to get to this answer. First and foremost, we will have to complete the square on the x terms and get everything else on the other side of the equals sign with the intention of putting this into standard form which looks like this:
[tex]-4p(y-k)=(x-h)^2[/tex]
The negative is because the parabola is upside down. We begin breaking it down by multiplying everything by -4 to get:
[tex]-4y=x^2+8x+8[/tex] and subtract that 8 from both sides to get:
[tex]-4y-8=x^2+8x[/tex]. Now we'll complete the square on the x terms by taking half the linear term, squaring it, and then adding it to both sides. Our linear term (the number with the x stuck to it) is 8. Half of 8 is 4 ad 4 squared is 16. So we add 16 to both sides to get:
[tex]-4y-8+16=(x^2+8x+16)[/tex]
The right side will simplify into a perfect square binomial and the left side we will just combine like terms to get:
[tex]-4y+8=(x+4)^2[/tex]
We're getting close. Now we need to just factor out the -4 on the left to get:
[tex]-4(y-2)=(x+4)^2[/tex]
If the standard form is -4p blah blah blah, then p has to be 1. That means that the focus is 1 unit below the vertex. The vertex is (-4, 2). p is the distance between the vertex and the focus. The focus is always on the axis of symmetry. We know that the parabola opens upside down because of the negative sign, and the parabola always wraps itself around the focus. That's why the focus is p units below the vertex. That means that the focus is located at (-4, 1).
Told you it was difficult. I noticed no one helped you with this one and it's been up here for 5 days...
A bakery sells bagels at two different rates. When a customer buys fewer than 12 bagels, each one costs $1.25. When a customer buys 12 or more bagels, the first 12 bagels cost $1 each and each additional bagel costs $0.75.
Which TWO inequalities and constraints below represent the price for b bagels??
Question 1 options:
1.25b when b 12
1b when b < 12, then 0.75b
1b when b ≤ 12, then 0.75b
0.75b for b < 12, then 1b
0.75b for b ≤ 12, then 0.75b
Answer:
1.25b when b < 12 , 1b & then 0.75 b when b > 12
Step-by-step explanation:
Price for b bagels = Price x Quantity* Less than 12 bagels bought, cost $1.25 per bagel
So, price for b bagels, when (b < 12) = 1.25b
* 12 or more than 12 bagels bought, cost $1 upto first 12 bagels & 0.75b on each additional bagel
So, price for b bagels, when (b = 12) = b
So, price for b bagels, when (b > 12) = b + 0.75b' , where b' denotes extra b beyond 12
The inequality used to represent this constraints is:
Price = 1.25b when b < 12
Price = 0.75b + 3 when b ≥ 12
Inequalities is an expression used to show the non equal comparison of numbers and variables.
Let b represent the number of bagels bought.
When a customer buys fewer than 12 bagels, each one costs $1.25. Hence:
Price = 1.25b when b < 12
When a customer buys 12 or more bagels, the first 12 bagels cost $1 each and each additional bagel costs $0.75. Hence:
Price = 12 + (b - 12)0.75 = 0.75b + 3 when b ≥ 12
The inequality used to represent this constraints is:
Price = 1.25b when b < 12
Price = 0.75b + 3 when b ≥ 12

f(x) = 2(x – 1)– 5 and g(x) = – 2x + 1 , determine the x-values of the points of intersection.
Answer:
x = 2Step-by-step explanation:
These are equations of lines with different slopes, so there is only one point of their intersect.
The point of intersect is where f(x) = g(x).
2(x - 1) - 5 = - 2x + 1
+2x +2x
2x - 2 - 5 + 2x = 1
+7 +7
4x = 8
÷4 ÷4
x = 2
Answer: x = 2
Explanation:
From the way you were referring to the x-values as plural, I assumed there were multiple x-values and multiple points of intersection, but these are linear equations, so one x-value it is!
Simply f(x)=2(x-1)-5 into f(x)=2x-7. Just plug in 2x-7, in order to make it equal to -2x+1. That would make the equation 2x-7=-2x+1. Add 7 to both sides to make it 2x=-2x+8. Add 2x to both sides to make it 4x=8. Divide 4 to both sides and that results with x=2.

Tia dilated the rectangle below by a scale factor of 7/2. What is ther perimeter of the new rectangle?
A
64 inches
B
220 inches
C
2695 inches
D
224 inches
Answer:
D. 224 inches
Step-by-step explanation:
Length of the new rectangle after dilation = 22 × ⁷/2 = 77 inches
Width of the new rectangle after dilation = 10 × ⁷/2 = 35 inches
Perimeter of rectangle = 2(length + width)
= 2(77 + 35)
= 2(112)
Perimeter = 224 inches
Mutual Fund X owns 0.5% of the total stock of Company Y. In one particular year, Company Y announces annual profits of $12,000,000, and decides to pay dividends to its shareholders at a rate of 15% of its annual profits. How much will Mutua
Answer: $9,000
Step-by-step explanation:
First calculate the total dividends that Company Y plans to pay.
= 12,000,000 * 15%
= $1,800,000
Then calculate the amount that Mutual fund X will get.
They own 0.5% of the total stock of Company Y so they will get;

Answer:
x = 6
Step-by-step explanation:
Rearrange terms
4 + 3 = 2 2
3 + 4 = 2 2
Subtract 4 from both sides of the equation
3x+4=22
3 + 4 − 4 = 2 2 − 4
Simplify (Subtract the numbers )
3 = 1 8
Divide both sides of the equation by the same term
3 = 1 8
3 / 3 = 1 8 /3

LOTS OF POINTS!?!?!?Write a linear function f with the values f(5)=−1 and f(0)=−1.
f(x)=
Answer:
The euation of the linear function is:
y = -1Step-by-step explanation:
As the function has the values
at x = 5, f(5) = -1at x = 0, f(0) = -1Thus, the two points are:
(5, -1)(0, -1)Finding the slope between (5, -1) and (0, -1)
[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]\left(x_1,\:y_1\right)=\left(5,\:-1\right),\:\left(x_2,\:y_2\right)=\left(0,\:-1\right)[/tex]
[tex]m=\frac{-1-\left(-1\right)}{0-5}[/tex]
[tex]m=0[/tex]
We know that the slope-intercept form of the line equation is
y=mx+b
where m is the slope and b is the y-intercept
We also know that the y-intercept can be computed by setting x=0 and finding the corresponding value of y.
so at x = 0, y = -1
Thus, the y-intercept 'b' = -1
Now, substituting m = 0 and b = -1 in the slope-intercept form of the line equation
y = mx+b
y = 0x + -1
y = -1
Therefore, the euation of the linear function is:

9514 1404 393
Answer:
563.5 cm³
Step-by-step explanation:
Use the formula for the volume of a cone:
V = (1/3)πr²h
Recognize that the radius is half the diameter:
r = (11.9 cm)/2 = 5.95 cm
V = (1/3)π(5.95 cm)²(15.2 cm) ≈ 563.516 cm³
The volume of the cone is about 563.5 cm³.

Additional comment
If you use 3.14 for the value of π, then the result will be 563.2 cm³.
