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

Step-by-step explanation:
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
Miss K and Mr. T were grading math tests. Miss K grades 9 tests per hour
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.
Miss K: 19, 27, 36. ( Took 3 hours to reach 36 tests)
Mr T: 29, 36. (Took 2 hours to reach 36 tests)
It will take Miss K 3 hours and Mr T 2 hours to have graded the same amount of tests (36).

helpp !! im helping my friend and i dont know how to do this, 6th grade stuff btw :((
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.
In Fairbanks, Alaska, the temperature on Tuesday at noon was -18℉. The temperature then decreased 1.2℉ each hour for the next 7 hours.
In Grand Forks, North Dakota, the temperature on Tuesday at 7pm was
¾ the temperature recorded in Fairbanks, Alaska at that same moment in time.
What is the temperature in Grand Forks, North Dakota?
Answer:
-19.8
Step-by-step explanation:
In Fairbanks , at noon -18
it decreased with 1.2 per hour for the next 7 hours .
so in total it decreased by 1.2 x 7 = 8.4
so at 7 pm it was -18-8.4 = -26.4
In Grand Forks at 7 pm 3/4 of -26.4 = -19.8

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)
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
Can someone help me solve this please
Step-by-step explanation:
Soln
From the above diagram
Height = h = 4cm
Let a&b = upward and downward lengths respectively.
That is:
a = 13cm
b = 16cm
recall that the formula used mathematically in solving/calculating the area of a trapezium is
Area = 1/2×(a+b)×h
Area = 1/2×(13+16)×4
Area = 1/2×(29)×4
Area = (29)×2
Area = 58cm²

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

Answer:
616
Step-by-step explanation:
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]
[tex]A=\frac{1}{2} (88)14[/tex]
[tex]A=\frac{1}{2} (1232)[/tex]
[tex]A=616[/tex]
Answer:
Step-by-step explanation:
Givens
h = 14
b1 = 34
b2 = 45
Formula
A = (b1 + b2)*h /2 Substitute into the formula
Solution
A = (34 + 45)*14/2 Combine the brackets
A = (79) * 14/2 Do the division
A = 79 * 7

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.
