The missing number in the ratios of numbers are 16:10 8:20 and 0:30
How to determine the missing numbers?Ratios are quantitative relationships between two numbers that describe how many times one value can contain another
the given parameters are
Forks 16 8 ----
Spoons 10 --- 30
The numbers are written in ascending order of magnitude
Using AP,
for forks: a = 16, 2nd term = 8
common difference = 8-16 - -8
For spoons a = 10, 3rd term = a + 2d = 30
30 = 10 + 2d
30 -10 = 2d
d= 20/2 = 10
Therefore the 2nd term = 10+10=20
The table reappears as follows
Forks 16 8 0
Spoons 10 20 30
Therefore the equivalent ratios are 16:10 8:20 and 0:30

A) 5
B) 6
C) 7
D) 8
Answer:
x + y = 5.2-----------------
Given system:
2x + 3y = 14 and3x + 2y = 12Add up the two equations to get same coefficient on both variables:
2x + 3x + 3y + 2y = 14 + 125x + 5y = 265(x + y) = 26x + y = 26/5x + y = 5.2As we see none of the choices match the answer. It means either question or answer choices are inaccurate.
If the prime factorization of 600 is 2 x 2 × 2 × 3 × 5 × 5, what would you need to multiply it by to get the prime factorization of 3000?
To get the Prime factorization of 3000 we need to multiply by 5.
What is Prime Factorization:When the number is factored using prime numbers, or primes, the process is known as prime factorization. The easiest method to determine the prime factors of a given number is to keep dividing the given number by the prime factors until we will get 1.
For example, the Prime factorization of 45 is given below
=> 45/5 = 9, 9/3 = 3, 3/3 = 1
=> 45 = 5 × 3 × 3
Here we have
The prime factorization of 600 is 2 x 2 × 2 × 3 × 5 × 5
Let us assume that on multiplying with p,
we will get the factorization of 3000
=> 2 x 2 × 2 × 3 × 5 × 5 × p = 3000
=> p = \(\frac{3000}{2\times 2 \times 2 \times 3 \times 5 \times 5}\)
Her 2 x 2 × 2 × 3 × 5 × 5 = 600
=> p = \(\frac{3000}{600}\)
=> p = 5
Therefore,
To get the Prime factorization of 3000 we need to multiply by 5.

find the maximum and minimum values of f(x)=x^3-3x^2-9x + 2
Answer:
minimum point is (3, -25) and maximum point is (-1, 7)
Step-by-step explanation:
f(x) = x³ - 3x² - 9x + 2
Differentiate:
f'(x) = 3x² - 6x - 9
Equal f'(x) to zero and solve to find values of x:
f'(x) = 0
3x² - 6x - 9 = 0
(x - 3)(x + 1) = 0
x = 3, -1
Plug in values of x into original function to find coordinates of turning/stationary points: (3, -25) and (-1, 7)
Differentiate again:
f''(x) = 6x - 6
Plug in x value of stationary points to find nature of point:
f''(3) = 6(3) - 6 = 12 > 0 ⇒ minimum
f''(-1) = 6(3) - 6 = -12 < 0 ⇒ maximum
Therefore, the minimum point is (3, -25) and maximum point is (-1, 7)
Jimi is a new content creator on TikTok. His followers are gradually increasing and can be calculated
using the function F(d) = d? + 30d,
where d is the number of days Jimi has been on TikTok. Based on this model, how many followers will Jimi have on day 10?
The number of follower Jimi have after the end of 10 days based on the given function is 310.
What is a function?A certain kind of relationship called a function binds inputs to essentially one output.
Given the function,
F(d) = d + 30d,
Where d = number of days Jimi has been on Tiktok
.
Now,
After 10 days ⇒ d = 10
So,
F(10) = 10 + 30(10)
F(10) = 10 + 300
F(10) = 310
Hence "The number of followers of Jimi after 10 days will be 310 based on the given function."

Solve the system of equations using the substitution or elimination method.

.
Show your work
Correct x and y
The solution to the system of equations is x = 1 and y = -3.
To solve the system of equations using the substitution or elimination method, let's start with the substitution method.
Given equations:
y = 4x - 7
4x + 2y = -2
We'll solve equation 1) for y and substitute it into equation 2):
Substituting y from equation 1) into equation 2):
4x + 2(4x - 7) = -2
4x + 8x - 14 = -2
12x - 14 = -2
Now, we'll solve this equation for x:
12x = -2 + 14
12x = 12
x = 12/12
x = 1
Now that we have the value of x, we can substitute it back into equation 1) to find y:
y = 4(1) - 7
y = 4 - 7
y = -3
Therefore, the solution to the system of equations is x = 1 and y = -3.

It is well documented that active maternal smoking during pregnancy is associated with​ lower-birth-weight babies. Researchers wanted to determine if there is a relationship between paternal smoking habits and birth weight. The researchers administered a questionnaire to each parent of newborn infants. One question asked whether the individual smoked regularly. Because the survey was administered within 15 days of​ birth, it was assumed that any regular smokers were also regular smokers during pregnancy. Birth weights for the babies​ (in grams) of nonsmoking mothers were obtained and divided into two​ groups, nonsmoking fathers and smoking fathers. The accompanying data are representative of the data collected by the researchers. The researchers concluded that the birth weight of babies whose father smoked was less than the birth weight of babies whose father did not smoke.

Answer:

Step-by-step explanation:
The relevant rules of exponents are ...
(ab)^c = (a^c)(b^c)
a^-b = 1/a^b
(a^b)(a^c) = a^(b+c)
(a^b)^c = a^(bc)
__
Applying these rules, we can simplify this expression as follows:
\(\dfrac{(3x^{-4})^6}{9x^{-12}}=\dfrac{3^6}{9}x^{(-4)(6)-(-12)}=81x^0=\boxed{81}\)
_____
Additional comment
The rules of exponents derive from the fact that an exponent indicates repeated multiplication. That is, x·x·x = x³, where the exponent 3 indicates x is a factor 3 times. When this idea is used for division, we see the exponent is the difference between numerator and denominator exponents:
(x·x·x)/(x·x) = x or x³/x² = x³⁻² = x¹ = x
This idea extends to cases where the denominator exponent is larger:
(x·x)/(x·x·x) = 1/x or x²/x³ = x²⁻³ = x⁻¹ = 1/x
This can help you see that moving a factor from numerator to denominator (or vice versa) changes the sign of its exponent.
__
This idea of repeated multiplication also applies when exponents are layered:
(x·x·x)(x·x·x) = (x³)² = x⁶ . . . . . the product exponent is the product of 3 and 2 as we indicated in the rules above

A rectangles area and perimeter have the same numerical value. The length of the rectangle is 22 feet. What is the width of the rectangle in feet?
Answer:
its 2,2
Step-by-step explanation:
2.4 is wrong
The width of the rectangle in feet will be 2.2 feet.
What is the rectangle?Let W be the rectangle's width and L its length. Then the area of the rectangle will be
Area of the rectangle = L × W square units
And the perimeter of the rectangle will be
Perimeter = 2(L + W)
A rectangle's area and perimeter have the same numerical value. The length of the rectangle is 22 feet. Then we have
L × W = 2(L + W)
22W = 2(22 + W)
11W = W + 22
10W = 22
W = 2.2 feet
The width of the rectangle in feet will be 2.2 feet.

if a small cup is 10 oz and cost 2.69 what is the cost per ounces
Answer:
The cost per ounce of the small cup is $0.269
Step-by-step explanation:
To find the cost per ounce, we can divide the cost of the cup by the number of ounces it holds.
Cost per ounce = Cost of the cup ÷ Number of ounces in the cup
Cost of the cup = $2.69
Number of ounces in the cup = 10 oz
So,
Cost per ounce = $2.69 ÷ 10 oz
Cost per ounce = $0.269 per oz (rounded to the nearest thousandth)
Therefore, the cost per ounce of the small cup is $0.269.
