Answer: 43.68 and 47.32
Step-by-step explanation: I took the test
In figure is shown a right circular cone of height 30 cm. A small cone is cut off from the top by a plane parallel to the base. If the volume of the small cone is 1/27 of the volume of given cone, find at what height above the base is the section made.
Answer:
20 cm
Step-by-step explanation:
Think of a large cone, 30 cm high, and a small cone of x height.
The scale factor of a volume of the cube of the scale factor of linear dimensions.
The cubic root of 1/27 is 1/3.
This means that the height of the small cone is 1/3 the height of the large cone.
The large cone has height 30 cm.
The small cone has height 10 cm.
30 cm - 10 cm = 20 cm
Answer: 20 cm

and has already graded 10. Mr. T grades 7 tests per hour and has already graded 22. After how many hours will they have graded the same amount of tests? How many tests will they have graded?
Step-by-step explanation:
Miss K has already graded 10 tests and is grading 9 every hour. We will add keep adding 9 starting from 10.
Mr. T has already graded 22 tests and is grading 7 per hour. We will keep adding 7 starting from 22.

what is 41% of 100?
hello!
the answer to your question is 41!
-----------
explanation:
- Step 1: Our output value is 100.
- Step 2: We represent the unknown value with [tex]x[/tex].
- Step 3: From step 1 above, [tex]100 = 100%[/tex]%
- Step 4: Similarly, [tex]x = 41%[/tex]%
- Step 5: This results in a pair of simple equations:
[tex]100 = 100% (1)[/tex]% (1)
[tex]x=41[/tex]% (2)
- Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both equations have the same unit (%); we have
[tex]\frac{100}{x}[/tex] = [tex]\frac{100}{41}[/tex]
- Step 7: Again, the reciprocal of both sides gives
[tex]\frac{x}{100}[/tex] = [tex]\frac{41}{100}[/tex]
Therefore, 41% of 100 is 41.
hope this helps! have a great day! :D

What is the area of the parallelogram
Answer:
24 square units
Step-by-step explanation:
For such questions it is convenient to choose the "base" to be a segment that is aligned with one of the coordinate axes. Here, the horizontal segments will serve. Their length is the difference between the x-coordinates of the end points, -2 -(-6) = 4, for example.
The height is measured perpendicular to the base, so will be the difference between the y-coordinates of the horizontal segments: 2 -(-4) = 6.
The area is given by the formula ...
A = bh
A = 4·6 = 24 . . . square units

The product of a number and twelve is seventy-two.
What steps would you take to translate the statement? Check all that apply.
Replace the word "product" with a symbol for division.
Replace the word "product" with a symbol for multiplication
Replace the words "a number" with a variable to represent an unknown value.
Replace "twelve" with 12
The correct equation is n = 12 = 72.
The correct equation is 12n = 72.
The product of a number and twelve is seventy-two.
So, the product of x and 12 is 72
12x=72
Therefore, the last one, 12n=72, is the right one

Answer:
81=5+b, 81-5=b, 81-b=5
Step-by-step explanation:
We can write the equation in terms of 81, b, or 5. Let's first start by writing it in terms of 81. We are already given that 5+b=81 therefore...
5+b=81 OR 81=5+b (transitive property)
Now, let's write the equation in terms of b.
5+b=81
Subtract 5 from both sides (subtraction property of equality)
5-5+b=81-5
b=81-5 OR 81-5=b (transitive property)
Lastly, let's write the equation in terms of 5.
5+b=81
Subtract b from both sides (subtraction property of equality)
5+b-b=81-b
5=81-b OR 81-b=5 (transitive property.
I need help fast…………
Answer & step-by-step explanation:
Look at the equation: you can rewrite it as [tex]y= x^2+4x+4 +1 = (x+2)^2+1[/tex]
Now the first term of the sum is at worst 0 (when [tex]x=-2[/tex]) so the sum is no less than 1.
Correct answer is the last option. Graph is the one in the photo, the thin red line is the axis - equation [tex]x=-2[/tex], vertex has coordinate [tex](-2;1)[/tex], Y intersect is [tex](0;5)[/tex] and has no x intercepts. extra points as needed if you want a more accurate graph, mine is sketched on paint so don't expect great quality

Based on percentage composition, the mass of recycled paper in Ophelia’s paper napkins is 203 g.
What is a percentage?A percentage gives an amount of a given quantity out of a whole value expressed in 100 units.
The total mass of the napkins = 580 g
b recycled paper in napkin = 35% of 580 g
Then;
The mass of recycled paper = 35/100 * 580 g
mass of recycled paper = 203 g
Therefore, the mass of recycled paper in Ophelia’s paper napkins is 203 g.

Joni bought 35 books at a price of Rp. 122,500. Toni bought the same 24 books as that Joni bought. How much did Toni pay for the book?
Answer:
Rs.84,000Step-by-step explanation:
Given,
Cost of 35 books Joni bought = Rs. 122,500
So,
Cost of 1 book = [tex]\frac{Rs. 122,500}{35}[/tex]
Now,
Same no. of books that Toni bought = 24
So, cost of 24 books
= [tex]\frac{Rs. 122,500}{35}[/tex] × 24
[On Simplifying]= Rs. 3500 × 24
= Rs. 84,000
Hence,
Cost of same amount of 24 books bought by Toni is Rs.84,000 (Ans)
Derek has a white cube and a red cube.
The numbers 1 to 6 are on the cubes. If
Derek tosses the cubes at the same time,
what is the probability he will get a 4 on
the white cube and a number greater than
4 on the red cube?
Answer:
1/72
Step-by-step explanation:
Probability of getting a 4 on white cube is:
P(W) · P(4) = 1/2 × 1/6 = 1/12
P(R) · P(>4) = 1/2 × 2/6 = 1/6
multiply both probabilities: 1/12 × 1/6 = 1/72

The equation to find the area of a trapezoid is: A = ½ (b[tex]^1[/tex]+b²) h.
b1=43
b2=45
h=14
Plug the variables in and solve.
[tex]A=\frac{1}{2} (43+45)14[/tex]
