r1 / r2 = sqrt(30) / sqrt(12)
r1 / r2 = sqrt(2)*sqrt(3)(sqrt(5) / sqrt(3) sqrt(4) but sqrt(4) = 2.
ri / r2 = sqrt(2)* sqrt(3)*sqrt(5) / sqrt(3) * 2 Now you can cancel out sqrt(3)
r1 / r2 = sqrt(2)*sqrt(5) / 2
r1 / r2 = sqrt(10)/2 <<<< answer

The volume of a rectangular prism is (x4 + 4x3 + 3x2 + 8x + 4), and the area of its base is (x3 + 3x2 + 8). If the volume of a rectangular prism is the product of its base area and height, what is the height of the prism?
Answers
[tex] \frac{x^{4}+4x^{3}+3x^{2}+8x+4}{x^{3}+3x^{2}+8}=x+1-\frac{4}{x^{3}+3x^{2}+8}[/tex]
The height of the prism is [tex]x+1-\frac{4}{x^{3}+3x^{2}+8}[/tex]
If the volume of a rectangular prism is the product of its base area and height, than the height of the prism is given by:
[tex]h = (x+1)-\dfrac{4}{(x^3+3x^2+8)}[/tex]
Given :
Volume of rectangular prism [tex]= x^4+4x^3+3x^2+8x+4[/tex]

Solution :
The volume of prism is the amount of space a prism occupies. It has two same faces and other faces that resemble a parallelogram.
Let the height of the prism be h.
Now, substitute the value of base area and volume of the rectangular prism in the given equation (1).
[tex](x^4+4x^3+3x^2+8x+4) = (x^3+3x^2+8)\times h[/tex]
[tex]\dfrac{x^4+4x^3+3x^2+8x+4}{x^3+3x^2+8}=h[/tex]

To find the mean, you simply add up all of the numbers in the sequence and divide by how many numbers are in the sequence.
43005+43007+43006+43005+43007=215030
215030 / 5 = 43006.
To find the mean:
1. Add all the numbers up
2. Divide the sum of the numbers by how many numbers there are
43005 + 43007 + 43006 + 43005 + 43007 = 215030
215030 ÷ 5 = 43006
$27.99 shoes ; 7 1/2 tax find the total cost or sale price to the nearest cent
Answers
27.99+2.10= $30.09
Answer:
$The total cost or sale price = $30.09
Step-by-step explanation:
The total cost or sale price is the absolute price of a commodity including the given tax.
From the question given, the tax is [tex]7\frac{1}{2}[/tex]% of the price. So that;
Tax = [tex]7\frac{1}{2}[/tex]% × 27.99
= 0.075 × 27.99
= 2.09925
∴ Tax = $2.09925
The total cost or sale price = price + tax
= $27.99 + $2.09925
= $30.08925
The total cost or sale price = $30.09

Two congruent triangles fit together to form a parallelogram with a base of 14 inches and a height of 10 inches. What is the area of each triangle?
Answers
After this you will divide the answer of 140 square inches by 2 because the area each congruent triangle would be half of the total area.
The answer is 70 square inches for each triangle.
Final answer:
The area of each triangle is 140 square inches.
Explanation:
The area of a triangle is given by the formula A = ½ × base × height.
In this case, the base of the parallelogram is 14 inches and the height is 10 inches.
Since two congruent triangles form the parallelogram, we can consider one of the triangles.
Let's call the base of the triangle 'b' and the height 'h'.
We have the equation A = ½ × b × h = 14 × 10 = 140 square inches.
Therefore, the area of each triangle is 140 square inches.

at a local animal shelter there are 12 small size dogs and 5 medium sized dogs everyday the small sized dogs are each given 12.5 oz of dry food and the medium sized dogs are each given 18 oz of the same dry food how many pounds of dry food does the shelter serve in one day
Answers
The shelter serves a total of 15 pounds of dry food per day, after calculating the food given to both small and medium-sized dogs and converting the total from ounces to pounds.
To calculate the total amount of dry food served at the shelter in one day, you must multiply the amount of food each dog consumes by the number of dogs of that size. Then, add the totals for each size category. Since the pound is the most suitable unit for this calculation, you need to convert the ounces of food into pounds. There are 16 ounces in one pound.
First, calculate the total food for small-sized dogs: 12 dogs × 12.5 oz each = 150 oz.Then, calculate the total food for medium-sized dogs: 5 dogs × 18 oz each = 90 oz.Combine the amounts: 150 oz + 90 oz = 240 oz of dry food total.Finally, convert ounces to pounds: 240 oz ÷ 16 oz per pound = 15 pounds of dry food.Therefore, the shelter serves a total of 15 pounds of dry food in one day.

For Part A, you just count the number of terms, there are 3. So, it is a trinomial.
For Part B, you look at the highest exponent value, it is 2. So it is a second degree polynomial.
For Part C, you have to sub in the values for each year. You are looking for the number of years since 1930, so subtract 1930 from each year.
2020 - 1930 = 90
2030 - 1930 = 100
Then, sub in those values into the given expression to find the density.
0.005(90)^2 - 0.127(90) + 1 = 30.07
0.005(100)^2 - 0.127(100) + 1 = 38.3

Substituting in the equation:

7x + 0 = -42
x = -6
For the y axis:

Substituting in the equation:

Answer:
Option A. greater than
Step-by-step explanation:
The percent of seventh graders surveyed who preferred fiction = 0.75 or 75%
The percent of eight graders surveyed who preferred fiction = 0.68 or 68%
Now we can say the percentage of seventh graders who preferred fiction is GREATER THAN the percentage of eight graders who preferred fiction.
Therefore option A. is the correct option.

You would multiply the bottom equation by -1 to make -6x a positive so you can eliminate it.
-6x + 6y = 6
6x + -3y = 12
Eliminate -6y and add 6y to -3y as well as 6 and 12.
0 + 3y = 18
3y = 18
divide both sides by 3
y = 6
now that you know the value of y it will be easy to find x :)
-6x + 3y = -12
✨ You need to eliminate a variable, so I'll use -1 to multiply the first equation by.
6x - 6y = -6
-6x + 3y = -12
-3y = -18
✨ y = 6
6x - 36 = -6
6x = 30
✨ x = 5
✨ The solution is (5,6) ✨

The value of the function (f/g) (5) is 270.
What is a function?A relation is a function if it has only One y-value for each x-value.
The given functions are f(x)=7+4x
g(x) = 1/2x
We need to find the value of f/g(5)
(f/g) (x) = f (x)/g(x)
(f/g) (5) = f (5) / g(5)
Now we will put the value of x = 5
f (5) = 7 + 4 (5) = 27
g (5) = 1 / (2)(5) = 1/10
(f/g) (5) = 27 / (1/10)
(f/g) (5) = 270
Hence, the value of the function (f/g) (5) is 270.
