Maya used a recipe in which 2 tablespoons of vinegar were mixed with 3 tablespoons of olive oil. Which statement about the amount of vinegar mixed with olive oil is true?
2 over 3 tablespoon of vinegar is mixed with every tablespoon of olive oil because the ratio of vinegar to olive oil is 2:3.
2 over 3 tablespoons of vinegar is mixed with every 5 tablespoons of olive oil because the ratio of vinegar to olive oil is 2:5.
2 over 5 tablespoons of vinegar is mixed with every 5 tablespoons of olive oil because the ratio of vinegar to olive oil is 2:5.
2 over 5 tablespoon of vinegar is mixed with every tablespoon of olive oil because the ratio of vinegar to olive oil is 2:3.
Answer:
Step-by-step explanation: becuase if the ratio is 2:3 then the ratio reduced to 1 would be 2/3:1
Answer:
(First Option): 2 over 3 tablespoon of vinegar is mixed with every tablespoon of olive oil
Step-by-step explanation
For every 2 tablespoons of vinegar, it was mixed with 3 tablespoons of olive oil. This leads to a ratio of 2:3, and that rules out option 2 and 3. To get the unit rate we divide 2 tablespoons of vinegar by 3 tablespoons of olive oil. This means that there is 2/3 tablespoons of vinegar for every tablespoon of olive oil and leads it to be answer choice 1.

Match the domain to the function
All positive integers All integers greater than or equal to 70 All positive integers less than 70 All integers greater than or equal to 14
All non-negative integers less than 14 All non-negative integers less than 70 All positive integers less than 14
Domain
Function
g(n)
Answer:All non-negative integers less than 70 for f(n) and All integers greater than or equal to 70
Step-by-step explanation:
It asks about the price before and after the free delivery.I’m not the best at explaining but I hope my answer helped.
The domain of the given functions are required.
The domain of [tex]f(n)[/tex] is All non-negative integers less than 14.
The domain of [tex]g(n)[/tex] is All integers greater than or equal to 14.
When the order is less than $70 a delivery charge of $89 is added and each plant costs $5.
The function representing the situation is
[tex]f(n)=89+5n[/tex]
If the order is or more than $70 then the function will be
[tex]g(n)=5n[/tex]
The domain of a function is the permissible values of [tex]n[/tex] for which the function is valid.
In the first function the number of plants that need to be bought so that the order will be 70 dollars would be
[tex]\dfrac{70}{5}=14[/tex]
So, only if less than 14 plants are bought then the first function can be used.
Also, the number of plants cannot be negative or zero hence it will be positive.
So, the domain of [tex]f(n)[/tex] is All non-negative integers less than 14.
In the second function the number of plants has to be 14 or more as it costs 70 dollars or more.
So, the domain of [tex]g(n)[/tex] is All integers greater than or equal to 14.

Critical Thinking: Data Transformation In this problem, we explore the effect on the standard deviation of multiplying each data value in a data set by the same constant. Consider the data set 5, 9, 10, 11, 15.
(a) Use the defining formula, the computation formula, or a calculator to compute s.
(b) Multiply each data value by 5 to obtain the new data set 25, 45, 50, 55, 75. Compute s.
(c) Compare the results of parts (a) and (b). In general, how does the standard deviation change if each data value is multiplied by a constant c?
(d) You recorded the weekly distances you bicycled in miles and computed the standard deviation to be s 3.1 miles. Your friend wants to know the standard deviation in kilometers. Do you need to redo all the calcula- tions? Given 1 mile 1.6 kilometers, what is the standard deviation in kilometers?
Answer:
Kindly check explanation
Step-by-step explanation:
Given the data : 5, 9, 10, 11, 15
s = √[(ΣX - m)² / (n - 1)]
n = number of sample = 5
m = mean
m = ΣX/n
m = (5 + 9 + 10+ 11 + 15) / 5
m = 50/5 = 10
s =√((5-10)^2 + (9-10)^2 + (10-10)^2 + (11-10)^2 + (15-10)^2) / 5-1
= 3.601
(B) Multiply each data value by 5 to obtain the new data set 25, 45, 50, 55, 75. Compute s.
m = ΣX/n
m = (25 + 45 + 50 + 55 + 75) / 5
m = 250/5 = 50
s =√((25-50)^2 + (45-50)^2 + (50-50)^2 + (55-50)^2 + (75-50)^2) / 5-1
= 18. 028
(c) Compare the results of parts (a) and (b). In general, how does the standard deviation change if each data value is multiplied by a constant c?
The standard deviation changes by almost c times multiplied by the initial value.
3.601 * 5 = 18.005 which is almost equivalent to 18.028
(d) You recorded the weekly distances you bicycled in miles and computed the standard deviation to be s 3.1 miles. Your friend wants to know the standard deviation in kilometers. Do you need to redo all the calcula- tions?
No
Given 1 mile 1.6 kilometers, what is the standard deviation in kilometers?
If 1 mile = 1.6km
s = 3.1 miles
s in kilometers = (1.6 * 3.1) = 4.96km
A ball is thrown straight up from the top of a building that is 400 ft high with an initial velocity of 64 ft/s. The height of the object can be modeled by the equation s ( t ) = -16 t2 + 64 t + 400.
In two or more complete sentences explain how to determine the time(s) the ball is higher than the building in interval notation.
Check the picture below.
the ball is higher than the building when y = 0, or namely when s(t) = 0, any other time is above it, and hmmm when it's that?
[tex]\stackrel{s(t)}{0}~~ = ~~-16t^2+64t+400\implies 0=-16(t^2-4t-25) \\\\[-0.35em] ~\dotfill\\\\ ~~~~~~~~~~~~\textit{quadratic formula} \\\\ 0=\stackrel{\stackrel{a}{\downarrow }}{1}t^2\stackrel{\stackrel{b}{\downarrow }}{-4}t\stackrel{\stackrel{c}{\downarrow }}{-25} \qquad \qquad t= \cfrac{ - b \pm \sqrt { b^2 -4 a c}}{2 a} \\\\\\ t= \cfrac{ - (-4) \pm \sqrt { (-4)^2 -4(1)(-25)}}{2(1)}\implies t=\cfrac{4\pm\sqrt{116}}{2}[/tex]
[tex]t=\cfrac{4\pm 2\sqrt{29}}{2}\implies t= \begin{cases} 2+\sqrt{29}~~\textit{\Large \checkmark}\\ 2-\sqrt{29} \end{cases}~\hfill \boxed{(0~~,~~2\sqrt{29})}[/tex]
notice, we can't use the 2-√29 because is a negative value and "t" is never negati ve, also notice the interval notation, we have parentheses on both sides.
What is the value of x in the triangle?
A: 10/2
B: 10
C: 20
D 20/2
E: 10/3
Answer:
[tex]A. 10\sqrt{2}[/tex]
Step-by-step explanation:
The triangle is a 45-45-90 triangle, which has the property that the side across from the 90°, in this case, x, is equal to one of the other sides multiplied by [tex]\sqrt{2}[/tex].
So:
10 x [tex]\sqrt{2}[/tex] = [tex]10\sqrt{2}[/tex]
The value of x in the given triangle is 10√2. So, correct option is A.
In triangle ABC, since angle B is a right angle, we can use the Pythagorean theorem to find the length of side AC (denoted by x).
The Pythagorean theorem states that in a right-angled triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides.
In this case, AB and BC are the two sides adjacent to the right angle:
AB² + BC² = AC²
Substitute the given values:
10² + 10² = x²
100 + 100 = x²
200 = x²
Now, to find the value of x, take the square root of both sides:
x = √200
Simplify the square root:
x = √(100 * 2)
x = 10√2
So, the value of x in the triangle is 10√2.
The correct answer is A: 10√2.

A water bottle has 16.9 fluid ounces of water. What is the total amount of water in a pack of 6 bottles?
Answer:
101.4 floz
Step-by-step explanation:
If I'm correct, you should multiply 16.9 by 6 because there are 6 bottles and each has 16.9 fluid ounces of water.
A water bottle has 16.9 fluid ounces of water, there would be a total of 101.4 fluid ounces of water.
We are given that each water bottle contains 16.9 fluid ounces of water. This is the capacity or volume of a single bottle.
To find the total amount of water in a pack of 6 bottles, we can multiply the amount of water in one bottle by the number of bottles in the pack.
Amount of water in one bottle: 16.9 fluid ounces
Number of bottles in the pack: 6
Total amount of water in the pack: 16.9 fluid ounces/bottle * 6 bottles = 101.4 fluid ounces
Therefore, there would be a total of 101.4 fluid ounces of water in a pack of 6 bottles.

3)45x^3-30x
Step-by-step explanation:
1)
Take 12x as a common factor
12x(3x-2)
12 since both 36 and 24 are divisible by 12
2)
Take 12x as a common factor again
12x(x-2)
3)
Take 15x as a common factor
15x(3x²-2)
3x²-2 can be written as the difference of 2 squares
15x(√3 x+√2)(√3 x-√2)
Answer:
[tex]12x(3x-2); 12x(x-2); 15x(3x^2-2)[/tex]
Step-by-step explanation:
Look at the coefficients of the first espression. 36 and 24 are both multiples of 12. We can collect 12x from both and we get
[tex]36x^2-24x=12x(3x-2)[/tex]
Second, 12 and 24 are obviously one twice the other, the common factor is again 12x:
[tex]12x^2-24x = 12x(x^2-2)[/tex]
Third polynomial: this time the greatest common divisor of 45 and 30 is 15. Let's collect 15x from either
[tex]45x^3-30x=15x(3x^2-2)[/tex]
