Answer: 27
Step-by-step explanation:
The expression given is inside a cube root. This is a simplified version of a fractional exponent, 1/3.
We can take the expression outside of the radical to get this:
3 ^ 9 ^ (1/3)
When an exponent is raised to another exponent, multiply the exponents and keep the base the same:
3 ^ (9 * 1/3)
3 ^ 3
The expression is equal to 27.

Answer:
76.275
Step-by-step explanation:
First - the entire circles area is 78.54. [tex]\pi r^{2}[/tex] with r being 5
6 triangles of that size could fit in that circle.
A=3[tex]\sqrt{3}[/tex]/(2) * a2
The area of that would equal 64.95
78.54-64.95 = 13.59
then divide that number by 6
which is 2.265.
Take that number from the original 78.54
78.54-2.265 = 76.275

Answers
A can of soup is a cylinder. We want to know how much soup can fill the can, which means that we are looking for the volume.
Formula for the volume of a cylinder: V = pi x r^2 x h
V = pi x 6^2 x 10
V = pi x 36 x 10
V = 360pi inches^3

Which of the following is the factored form of the goven equation? 6x² + 2x - 8 = 0
A. 2(3x+4)(x+1) = 0
B. (6x+1)(x-8)=0
C. 2(3x+4)(x-1)=0
Answers
Answer:
C
Step-by-step explanation:
6x^2 + 2x - 8
Multiply the (6) to the -(8) to get x^2 by itself.
x^2 + 2x - 48
Solve -
(x-6)(x+8) = x^2 + 2x - 48
However, you must divide out the (6) you multiplied.
(x-6/6) =
(x-1)
(x+8/6) =
(3x + 4)
Therefore, 2(3x + 4)(x-1) is your answer.

Quincy folds a piece of cardboard to make the three sides of a triangular prism open at top and bottom. The triangle prism and the piece of cardboard that he used are show below. What is the area of the piece of cardboard?
Answers
This question is incomplete because it lacks the attached diagram.
Find attached to this answer the appropriate diagram
Answer:
500 square centimeters
Step-by-step explanation:
From the question above, we are told that the top and bottom of the triangular prism is open.
Hence, the area of the piece of the cardboard is = Lateral Surface Area of the triangular prism
The formula for Lateral Surface Area of a Triangular Prism = Perimeter of the Triangular prism × Height of the Triangular prism.
Perimeter of the Triangular prism = Side a + Side b + Side c
Where Side a = 9cm
Side b = 9cm
Side c = 7 cm
Perimeter of the Triangular prism = 9cm + 9cm + 7cm
= 25cm
Height of the Triangular prism = 20cm
The Lateral Surface Area of the Triangular prism = 25cm × 20cm
= 500cm² or 500 square centimeters.
Since we are told that Lateral Surface Area = Area of the cardboard,
The Area of the cardboard = 500 cm² or 500 square centimeters.

Answers
Answer:
5.28 kg
Step-by-step explanation:
A farmer sells 8.8 kilograms of pears and apples at the farmer's market and 2/5 of this weight is pears.
Since a fraction is a part of a whole, 1, then, the fraction repressing the weight of the apples is:
1 - 2/5 = 3/5
Therefore, the weight of apples is/
3 / 5 * 8.8 = 5.28 kg
She sold 5.28kg of apples at the farmer's market.

Answer:
CD player X
Step-by-step explanation:
In this question we are asked to compare 3 CD prices to each other and see which one is the cheapest. We will need to use something called decimal multipliers for this question. We will work out the price of each CD player and then analyse after that. To work out the decimal multipliers for decrease question you have minus 100 and then divide by 1 hundred.
CD player X
→ A price of 1500 and 20% off
⇒ Work out the multiplier with the 100 and then divide by a hundred
→ 100 - 20 = 80 → 80 ÷ 100 = 0.8 So the decimal multiplier is 0.8
⇒ Now multiply the price by the decimal multiplier
→ 1500 × 0.8 = 1200
-------------------------------------------------------------------------------------------------------
CD player Y
→ A price of 2000 and 30% off
⇒ Work out the multiplier with the 100 and then divide by a hundred
→ 100 - 30 = 70 → 70 ÷ 100 = 0.7 So the decimal multiplier is 0.7
⇒ Now multiply the price by the decimal multiplier
→ 2000 × 0.7 = 1400
-------------------------------------------------------------------------------------------------------
CD player Z
→ A price of 1800 and 25% off
⇒ Work out the multiplier with the 100 and then divide by a hundred
→ 100 - 25 = 75 → 75 ÷ 100 = 0.75 So the decimal multiplier is 0.75
⇒ Now multiply the price by the decimal multiplier
→ 1800 × 0.75 = 1350
We can see the CD player X is the one that saves the most money
Answer:
Therefore, the CD player X is worth buying, since it only costs 1,200.
CD player X: 1,200
CD player Y: 1,400
CD player Z: 1,350
Step-by-step explanation:
Formula:
discount amount/original price = discount%/100%
For CD player Z:
discount amount = x
original price/regular price = 1,800
discount% = 25%
For CD player Y:
discount amount = x
original price or regular price = 2,000
discount% = 30%
For CD player X:
discount amount = x
original price or regular price = 1,500
discount% = 20%
______________________________
For CD player Z
x/1,800 = 25/100
x ⋅ 100 = 25 ⋅ 1,800
100x = 45,000
100x/100 = 45,000/100
x = 450
For CD player Y
x/2,000 = 30/100
x ⋅ 100 = 30 ⋅ 2,000
100x/100 = 60,000/100
x = 600
For CD player X
x/1,500 = 20/100
x ⋅ 100 = 20 ⋅ 1,500
100x = 30,000
100x/100 = 30,000/100
x = 300
_________________________
Formula:
Sale price = original price - discount
For CD player Z: 1,800 - 450 = 1,350
For CD player Y: 2,000 - 600 = 1,400
For CD player X: 1,500 - 300 = 1,200

Round to nearest hundreth
Answers
Answer: The answer is 33.69!
Step-by-step explanation: When performing trigonometric problems it is important to pay attention to all of your sides even when you are finding a missing angle. The sides will show you which of the sides to divide over the other, and which equations to perform. In this case the number 6 is opposite of the missing angle and the number 9 is the adjacent or “right next to.” Hence, you are left with the Opposite side and the adjacent since the Hypotenuse is unused in this problem due to it being unlabeled. So 6 divided by 9 times the opposite of tangent which is Tan^-1 or on a basic calculator you would do the division first and then press the second key or secondary operations key. Then there will be a number in which shows you the exact angle in which you were missing.
Also learning the terms “SOH” “CAH” and “TOA” will help you exponentially when trying to find the equations to use. SOH: also known as Sine - is opposite over hypotenuse due to its alphabetical placement. Along with Cosine - adjacent over hypotenuse and Tangent which was the case of this triangle - opposite over adjacent.

The company fired all of its math people so they do not know how to calculate the size of the tube needed. Please calculate the surface area needed for the tube. Use 3.14 for pi. *
Answers
Answer:
[tex] A= 2\pi (3cm)^2 +1 2\pi (3cm)(10 cm)= 18 \pi + 60\pi = 78 \pi cm^2[/tex]
And replacing the value of [tex]\pi =3.14[/tex] we got:
[tex] A = 78*3.14 cm^2= 244.92 cm^2[/tex]
Step-by-step explanation:
For this case we have the long who represent the height 10 cm and the diameter is 6cm. So then the radius is given by:
[tex] r = \frac{D}{2}= \frac{6cm}{2}= 3cm[/tex]
And the surface area for a cylinder is given by this formula:
[tex]A= 2\pi r^2 +2 \pi rh[/tex]
And replacing the info given we got:
[tex] A= 2\pi (3cm)^2 +1 2\pi (3cm)(10 cm)= 18 \pi + 60\pi = 78 \pi cm^2[/tex]
And replacing the value of [tex]\pi =3.14[/tex] we got:
