Use the ALEKS calculator to write as a percentage.
5/17
Round your answer to the nearest tenth of a percent.

Answers

Answer:

The answer is 29.4%

Step-by-step explanation:

The given is to be rounded to the nearest tenth percent so

5/17 = 0.294

0.294 * 100 = 29.4% since nearest tenth percent

The required answer is 29.4%

Given fraction is 5/17.

Percentage is a way of expressing a fraction or proportion as a portion of 100. It is a mathematical concept used to represent relative quantities or values in terms of hundredths. The word "percent" is derived from the Latin words "per centum," which mean "per hundred." It is denoted by the symbol "%".

To convert a fraction to a percentage, and multiply the fraction by 100.

Let a and b be the rel numbers. To convert the fraction a/b into percentage by multiply the fraction by 100.

That is , a/b x 100.

And on simplification gives the fractions.

To convert 5/17 to a percentage, we have:

(5/17) x 100 = 29.4117647...

Rounding this to the nearest tenth of a percent, we get:

29.4%

Therefore, when rounded to the nearest tenth of a percent, 5/17 is approximately 29.4%.

Answers

Answer:

x = 36 degrees

y = 48 degrees

Step-by-step explanation:

The two given triangles are congruent

Hence, we can say that the interior angles are equal

We shall use the angle markings on each of the triangles

Using the markings, we can see that y is 48 degrees

Now, let us find the last angle measure of the first triangle

Mathematically, the sum of angles in a triangle is 180

Thus;

108 + 48 + A = 180

A = 180 - 48 - 108

A = 180 - 156 = 24

Now, the measure 2x-y is equal to this;

Hence;

2x -y = 24

2x = 24 + y

we have that y = 48

2x = 24 + 48

2x = 72

x = 72/2

x = 36 degrees

(-3, -4)

Step-by-step explanation:

The solution is where the two lines intersect. Therefore, the x-coordinate is -3, and the y-coordinate is -4.

Another way to solve this would be to set the to equations equal to each other, so 2x+2 = -4. Therefore, 2x = -6, and x = -3. And from the second equation, y = -4.

What is the volume of a hemisphere with a radius of 4.9 ft, rounded to the nearest
tenth of a cubic foot?

Answers

The volume of the hemisphere with the given value of radius to the nearest tenth is 246.4 cubic foot.

Hemisphere

A hemisphere is gotten when a sphere is cut into two equal halves.

The volume of a hemisphere is expressed as;

V = (2/3)πr³

Where r is the radius and π is pi ( π = 3.14 )

Given the data in the question;

Radius of the hemisphere r = 4.9ftVolume of the hemisphere V = ?

To determine the volume of the hemisphere, we substitute our values into the expression above.

V = (2/3)πr³

V = (2/3) × π × (4.9ft)³

V = (2/3) × π × 117.649ft³

V = 246.4ft³

Therefore, the volume of the hemisphere with the given value of radius to the nearest tenth is 246.4 cubic foot.

Step-by-step explanation:

Cylinder Formulas in terms of r and h

Calculate the volume of a cylinder: V = πr2h

Calculate the lateral surface area of a cylinder (just the curved outside)**: L = 2πrh

Calculate the top and bottom surface area of a cylinder (2 circles): T = B = πr2

Total surface area of a closed cylinder is: A = L + T + B = 2πrh + 2(πr2) = 2πr(h+r)

Step-by-step explanation:

Given :

- x^ 2 - 8 = - 33

to find :

find ''x''

explanation :

⟼ - x^ 2 - 8 = - 33

step 1 : add 8 to both sides

⟼ − x² − 8 + 8 = − 33 + 8

⟼ - x² = - 25

step 2 : Divide both sides by -1

⟼ - x² / - 1 = - 25 / - 1

⟼ x² = 25

step 3 : take square root

⟼ x² = 25

⟼ x = ± √25

⟼ x = ± 5

x = ± 5.
