Answer:
B. 10.75 cu. in.
Step-by-step explanation:
Vol. of cylinder = π[tex]r^{2}[/tex]h = 32.25
If the cone has the same radius and height,
then the vol. of the cone = π[tex]r^{2}[/tex]h/3 = 32.25/3 = 10.75 cu. in.
The perimeter of a certain square is 4 yards. Find the area of the square in square feet.
Please someone help
Step-by-step explanation:
Write what you know
A square has 4 sides
the perimeter is the sum of the length of all 4 sides
so 4yards / 4 sides = 1 yard per side
we also know a square has all equal sides
that means our area formula will be 1 x 1
help please this makes no sense
Factor the expression 36a4b10 81a16b20 using the two different techniques listed for Parts 1(a) and 1(b). (a) Factor the given expression using the GCF monomial. (a) Factor the given expression using the GCF monomial. (b) Factor the given expression using the difference of squares.
Answer:
The answer is "[tex]9a^4b^{10}(2+6a^6b^5)(2-6a^6b^5)[/tex]"
Step-by-step explanation:
For point a:
[tex]36a^4b^{10} - 81a^{16}b^{20}[/tex] by GCF
Calculating the const terms:[tex]36 \ n \ 81, \ GCF \ is\ 9\times 4 \ n \ 9\times 9[/tex]
Calculating the terms [tex]w\ a: a^4 \ n \ a^{16},\ GCF \ is\ a^4 \ n \ a^4 \times \ a^{12}[/tex]
Calculating the terms [tex]w \ b: b^{10}\ n\ b^{20}, \ GCF \ is\ b^{10}\ n \ b^{10} \times b^{10}[/tex]
Including the GCFs, [tex]36a^4 b^{10} - 81a^{16}b^{20}[/tex]
[tex]=9a^4b^{10}(4 - 9a^{12}b^{10})\\\\4=2^2 n 9a^{12}b^{10}\\\\=(3a^6b^5)^2[/tex]
Calculating the difference of squares
[tex]\to A^2 - B^2 = (A+B)(A-B)\\\\\to 4 - 9a^{12}b^{10} \\\\\to (2+3a^6b^5)(2-3a^6b^5)\\\\[/tex]
substituting
[tex]\to 36a^4b^{10} - 81a^{16}b^{20}\\\\\to 9a^4b^{10}(2+3a^6b^5)(2-3a^6b^5)[/tex]
For point b:
Calculating the difference of squares:
[tex]A^2 - B^2 = (A+B)(A-B)\\\\36a^4b^{10}=(6a^2b^5)^2\\\\81a^{16}b^{20}=(9a^8b^{10})^2\\\\36a^4b^{10} - 81a^{16}b^{20}\\\\=(6a^2b^5+9a^8b^{10})(6a^2b^5-9a^8b^{10})\\\\=3a^2b^5(2+6a^6b^5)3a^2b^5(2-6a^6b^5)\\\\=9a^4b^{10}(2+6a^6b^5)(2-6a^6b^5)[/tex]

Mayra bought a pair of sneakers. They originally cost $75 but were on sale for 15% how much mony did she save
Answer: $11.25
Step-by-step explanation:
Since the sneakers were on sale for 15% less, the amount she bought them will be:
= (100% - 15%) × $75
= 85% × $75
= 0.85 × $75
= $63.75
Therefore, the amount she saved will then be:
= $75 - $63.75
= $11.25
She saved $11.25

4 cans of orange juice and 7 cans of apple juice are in a sports bags what is the probability of drawing out one can of apple juice without looking? write your answer as a decimal rounded to two decimal places.
Answer:
1.36
total cans =11
the prob. of drawing orange juice can= 4/11
the prob of drawing apple juice can= 7/11
the prob of drawing any of the juice= 4/11 + 7/11
= 15/11
= 1.36

4 x 3.14 = 12.56
12.56 x 8(height) = 100.48
100.48 divided by 3 ( x 1/3 ) = around 33.49 in3 is your answer.
If the options dont give you 33.49 just go by 33.51 cubic meters.

Jim was thinking of a number. Jim doubles it, then adds 19 to get an answer of 70.1. What was the original number?
Answer:
25.55
Step-by-step explanation:
Let us take the number he thinked of be x .
On doubling it :-
→ N = 2x
On adding 19 :-
→ N = 2x + 19
According to Question :-
→ 2x + 19 = 70.1
→ 2x = 70.1 - 19
→ 2x = 51.1
→ x = 51.1/2
→ x = 25.55
Hence the required answer is 25.55HELPP!! this is due in like 30 minutes and i have to get this done! someone pls help

Write a rule for g described by the transformations of the graph of f.
Let g be a horizontal shrink by a factor of 3/7, followed by a translation 5 units left
of the graph of f(x)=(21x)^1/2
Answer:[tex]g(x)=\frac{3}{7}(21(x+5))^{1/2}[/tex]
Step-by-step explanation:
Transformation rule:
Shifting by k units left : [tex]f(x)\to f(x+5)[/tex]
Dilation by a factor of h units: [tex]f(x)\to hf(x)[/tex]
Let g be a horizontal shrink by a factor of 3/7, followed by a translation 5 units left of the graph of [tex]f(x)=(21x)^{1/2}[/tex]
The rule for g described by the transformations of the graph of f. : [tex]g(x)=\frac{3}{7}(21(x+5))^{1/2}[/tex]

find the slope between (-3,2) and (-7,-16)
Answer: The slope between these two is 3.5
Answer:
Solpe=4.5
Step-by-step explanation:
Sorry if I’m wrong, but I think I got it.
So the formula for slope is y2-y1/x2-x1
In (-3,-2) )-7,-16), -3 is x1, -2 is y1, -7 is x2, and -16 is y2.
Now, you need to fill in the formula with these numbers.
-16-2/-7- - 3
-16-2 is -18
-7- - 3 is -4 (two negatives make a positive)
This makes -18/-4. Divide this to get 4.5.

Sin0=20/29 find tan 0
Answer:
Step-by-step explanation:
here opposite =20, hypotenuse=29
to find adjacent use formula
a^2+b^2=c^2
20^2+b^2=29^2
400+b^2=841
b^2=841-400
b=[tex]\sqrt{441\\}[/tex]
b=21
tan theta=opposite/adjacent
=20/21
therefore tan theta =20/21
Answer:
D. tanθ = 20/21
Step-by-step explanation:
Remember that sinθ = opposite/hypotenuse. In this case, since sinθ = 20/29, we are going to say that opposite = 20 and hypotenuse = 29.
To solve for the adjacent side, use the Pythagorean theorem, a^2 + b^2 = c^2.
When you plug in your values and solve for the other leg, you'll get 21.
Now that we know that the adjacent side/other leg is equal to 21, we can find tanθ, since it's equal to opposite/adjacent.
Opposite = 20
Adjacent = 21
tanθ = 20/21

A store sells 1 3/4 pound package of roast beef for $12. what is the unit price?
Answer:
Unit price of roast beef = $6.86
Step-by-step explanation:
Given:
Cost of [tex]1\frac{3}{4}[/tex] pound package of roast beef = $12
Find:
Unit price of roast beef
Computation:
Unit price of roast beef = Cost of 1 pound package of roast beef
[tex]1\frac{3}{4}[/tex] pound package of roast beef = 7 / 4 = 1.75 pound package of roast beef
Cost of 1 pound package of roast beef = Total cost / Total mass
Cost of 1 pound package of roast beef = 12 / 1.75
Cost of 1 pound package of roast beef = 6.857
Unit price of roast beef = $6.86
