Find the volume of a sphere with a surface area of 2916 squared pi

Answer:

32

Step-by-step explanation:

So the order of the points is: GHJK

GH = x+10 =JK

HJ=8

JK=2x-4

JK = x+10=2x-4

x+10=2x-4

10+4=2x-x

x=14

GH= 14+10 =24

GJ = GH +HJ = 24+ 8=32

Answer:

6859 is not perfect cube.

Step-by-step explanation:

First we will find all factors under the cube root: 6859 has the cube factor of 361. Let's check this width ∛361*1=∛6859. As you can see the radicals are not in their simplest form. Now extract and take out the cube root ∛361 * ∛1. Cube of ∛361=19 which results into 19∛1 All radicals are now simplified.

Answer:

297cm^3π

Step-by-step explanation:

R is a radius of the base of a cone, and r of top surface radius.

V=(1/3)×π×depth×(r^2+r×R+R^2)

V=(1/3)×π×3cm×(3^2+3×4.5×4.5^2)

V=(1/3)×π×3cm×(9cm^2+3cm×4.5cm×20.25cm^2)

V=(1/3)×π×3cm×(12cm^2×24.75cm^2)

V=(1/3)×π×3cm×(297cm^4)

V=(1/3)×π×891cm^3

V=(891cm^3/3)π

V=297cm^3π

Answer:

≈64.08

Step-by-step explanation:

Lateral Area=πr[tex]\sqrt{h^{2} +r^{2} }[/tex]

Radius is 1/2 of the diameter so r=2

Height=10

Substitute:

: [tex]3.141(2)\sqrt{10^{2}+2^{2} } \\6.282\sqrt{100+4} \\6.282\sqrt{104} \\ 64.066.282*10.2\\ 64.076\\\\[/tex]

64.076 rounded = 64.08

Answer:

[tex]45.4 cm^2[/tex]

Step-by-step explanation:

The area of the sector of a circle is given as:

[tex]\frac{\alpha }{360} * \pi r^2[/tex]

where α = central angle of the sector

r = radius

The central angle of the sector is 160° and its radius is 5.7 cm. Its area is:

A = [tex]160/360 * \pi * 5.7^2[/tex]

A = [tex]45.4 cm^2[/tex]

Answer:

£60

Step-by-step explanation:

Let [tex]x[/tex] be the original price.

[tex]x \times (1-10/100) = 54[/tex]

[tex]x \times 90/100 = 54[/tex]

[tex]0.9x=54[/tex]

[tex]x=54/0.9[/tex]

[tex]x=60[/tex]

Answer:

A) 29men

B) 91cm

C) 13cm

Step-by-step explanation:

Men with waist of 85cm = 11

A.) Men with waist of more than 85cm = (total number of men - 11) = (40 - 11) = 29men

B.) median waist :

Median = (n) / 2

Where n = number of observations

Median = (40) / 2 = 40/2 = 20th

Taking the intersection of the 20th point on the x-axis,

Median waist = 91cm

C.) Interquartile range(IQR) = (Q3 - Q1)

Q3 = 3/4(n)

Q3 = 0.75 × 40 = 30

Q3 = 97cm

Q1 = 1/4(n)

Q1 = 0.25 × 40 = 10

Q1 = 84cm

IQR = 97 - 84 = 13cm

Answer:

£537.63

Step-by-step explanation:

Let the original price of the computer be x.

The price of a computer was decreased by 7% to £500. This implies that:

x - 7/100 * x = 500

x - 0.07x = 500

0.93x = 500

x = 500/0.93 = £537.63

The price before the decrease was £537.63.

Answer:

6.5%

Step-by-step explanation:

M.P= ₹6,000

Amount excluding VAT= 5,610

discount= x/100

discount= 6000*x/100=60x

equating

6000-60x= 5610

6000-5610=60x

390=60x

390/60=x

6.5=x

therefore, there is a discount of  6.5%

Answer:

The slope is -3

Step-by-step explanation:

This is so because the line in pointing down, leading to the fact that the slope is negative, and rise over run is 3/1......

Therefore, the slope of the line is -3

To find the slope of the line, first start with a point on the graph.

Let's use the point (0,3) which we call point A.

The other point we will call point B.

Now remember that slope can be found using the ratio rise/run

between any two points that are on that line.

To get from point A to point B along this line, we must

first go down 3 units so we say that our rise is -3.

From there we move 1 unit to the right so our run is 1.

So our slope or rise/run is -3/1 which reduces to -3.

perimeter is 35.6 area is 108

Step-by-step explanation:

it helps to draw a picture. first the perimeter of the rectangle is 4x2 +12=20 we wont be needing one of the twelves because it is connected to the triangle the area or the rectangle is 12x4=48. now for the triangle. we will need the Pythagorean theorem to find the sides first split the base in half 12/2=6 now we use the height and the base [tex]6^{2} +5x^{2} =[/tex]61 the square root of 61 is about 7.8 the perimeter is 7.8+7.8 +12 but we wont need the base because it is attached to the rectangle =15.6 the area of the triangle is like half a square Base times height though 12x5=60

the whole perimeter if 15.6+20=35.6 the area is 60+48=108

Answer:

[tex]\frac{7}{20}[/tex]

Step-by-step explanation:

First, add the shares of the first two investors

[tex]\frac{1}{4} +\frac{2}{5} = \frac{13}{20}[/tex]

Then, you subtract that from the total shares of the company, which is 1

[tex]1 - \frac{13}{20} = \frac{7}{20}[/tex]

Answer:

Step-by-step explanation:

First of all, remember that [tex]sin(0)=0[/tex] and [tex]cos(0)=1[/tex]. As you can see, the sine function won't be affect by [tex]a[/tex], because its value is null.

However, the x-intercept of the cosine function depends on the [tex]a[/tex] value, because the function is equal to the unit.

On the other hand, the variable [tex]b[/tex] won't affect any function, because it would be always zero.

Therefore, the sine function won't be affected, but the consine function will.

360/18=20

20*7=140

20*6=120

20*5=100

Answer=140:120:100

Answer: smallest share is 100

Step-by-step explanation:

7:6:5

Add the numbers so 7+6+5=18

Divide 360 by 18 which equals 20

Multiply each ratio by 20 so...

7×20:6×20:5×20

Answer:

15 total students

Step-by-step explanation:

Based on the line plot picture that is attached below it can be calculated that a total of 15 students spent 5 or more hours last week reading. This can be easily calculated by adding all the x's on the marks of 5 hours or more. With both the boys and girl students combined the tally was the following

5 hours : 4 students

6 hours : 1 student

7 hours : 3 students

8 hours : 3 students

9 hours : 0 students

10 hours: 2 students

11 hours : 2 students

12 hours : 0 students

adding up to 15 total students

Answer:

Is answer is option B

Answer:

B

Step-by-step explanation:

Given the 2 equations

x - 2y = 3 → (1)

2x - 3y = 9 → (2)

Multiplying (1) by - 2 and adding to (2) eliminates the term in x

- 2x + 4y = - 6 → (3)

Add (2) and (3) term by term to eliminate x, that is

y = 3

Substitute y = 3 into either of the 2 equations and solve for x

Substituting into (1)

x - 2(3) = 3

x - 6 = 3 ( add 6 to both sides )

x = 9

Solution is (9, 3 ) → B

Answer: (A) [tex]12+12\sqrt{12}[/tex] .

Step-by-step explanation:

Perimter is the sum of the all sides of a figure.

As the given design has three exactly same or identical triangles with side-lengths [tex]2\sqrt{2}\ in, 2\sqrt{2}\ in, 4\ in[/tex] joined by ending vertices.

Then, the combined operimetr of thge design would be :

3 x (Perimeter of the one triangle)

For this , Perimeter of one triangle = [tex]2\sqrt{2}+2\sqrt{2}+4\ in =(4\sqrt{2}+4) = 4(\sqrt{2}+1) \ in[/tex]

Now , the combined operimetr of thge design would be :

[tex]3\times4(\sqrt{2}+1)=12(\sqrt{2}+1)\ in[/tex]  or   [tex]12+12\sqrt{12}\ in[/tex]

Hence, the correct option is (A) [tex]12+12\sqrt{12}[/tex] .

Answer:

Step-by-step explanation:

Let's solve 2x^2 = -X^2 - 5x - 1.  Consolidate all terms on the left side and write 0 on the right side:

3x^2 + 5x + 1 = 0.  This is a quadratic equation.  Let's solve it for x using the quadratic formula:

a = 3, b = 5, c = 1, and so the discriminant is b^2 - 4ac = 5^2 - 4(3)(1) = 13.  Because the discriminant is positive, we know that there are two distinct, real roots; the graphs of y = 2x^2 and y = x^2 - 5x - 1 intersect in two places whose x-coordinates are the real roots mentioned above.

Answer A is not correct as stated, but would be correct if we were to replace "the y-coordinates" with "the x-coordinates."  

Answer C would be correct if and only if we write y = x^2 - 5x - 1.

Answer:

C: the x-coordinates of the intersection points of the graphs of y = 2x2 and y = –x2 – 5x – 1
