Answer:

  (d)  12.3

Step-by-step explanation:

From the Law of Cosines, you can solve for c:

  c = √(a² +b² -2ab·cos(C)) = √(22.09 +104.2441 -95.974cos(105.3°))

  c ≈ √151.659 ≈ 12.31499

Side c is about 12.3 units long.

Answer:

0.83

Step-by-step explanation:

It’s right use the formula they give you

The probability of a student taking the bus given that the student is sophomore is 0.83

Given that:

P(Walk to school | Sophomore) = 3 /(2 + 25 + 3) = 0.1

To cal culate the probability of a student taking the bus given that the student is sophomore, we make use of:

P(Take the bus | Sophomore ) = 25/(2 + 25 + 3)

Rewrite properly as:

[tex]Pr= \frac{25}{2 + 25 + 3}[/tex]

So, we have:

[tex]Pr= \frac{25}{30}[/tex]

Divide 25 by 30

[tex]Pr= 0.83[/tex]

Hence, the probability of a student taking the bus given that the student is sophomore is 0.83

Answer:

Volume of pyramid =1/3× Area of base × height

Since the base is a square

Area of base = l²

l = length

= 6²

= 36ft²

Height of pyramid = 5ft from the diagram above

Volume = 1/3× 36ft² × 5ft

= 60ft³

Answer:

Answer of the Sophie solves the problems= 18

Lily solves the problems= 53

Step-by-step explanation:

Sophie solve the problem =x

Lily solve the problem =3x-19

Sophie and lily solve the problems together

(x)+ (3x-19)=53

x+3x-19=53

4x=72

Sophie x=18

3x-19=Lily

3(18)-19= Lily

Answer:

2x² + x - 1 = 0

a= 2 b= 1 c= -1

x = [ -b +- sqr rt( b^2 -4ac) ] / 2*a

x = -1 +- sqr rt (1 - 4 *2*-1) / 4

x1 = [ -1 + (sqr rt (1 +8)) / 4

x1 = ( -1 + sqr rt (9)) / 4

x1 = (-1 + 3) / 4

x1 = .5

x2 = (-1 -3) / 4

Answer:

4.30 inches

Step-by-step explanation:

Given data

Volume of basket ball= 334cubic inches

We know that the expression for the volume of a sphere is given as

Volume of sphere= 4/3πr^3

334= 4/3πr^3

334=4/3*3.142*r^3

334=4.189*r^3

r^3= 334/4.189

r^3=79.73

cubic root both sides

r= ∛79.73

r=4.30 inches

Answer:

38

Step-by-step explanation:

Answer:

38

Step-by-step explanation:

The question is incomplete. The complete question is :

A sphere and a cylinder have the same radius and height. The volume of the cylinder is 54 meters cubed. Amie found the volume of the sphere. A sphere with height h and radius r. A cylinder with height h and radius r. Her work is shown below. V = two-thirds + 54. V = two-thirds + StartFraction 162 Over 3 EndFraction. V = StartFraction 164 Over 3 EndFraction meter cubed. What is Amie's error?

Solution :

Amie should have multiplied 54 by two-thirds.

Given that sphere and the cylinder have the same radius as well as same height. The volume of the cylinder is 54 inch cube.

Volume of the sphere = [tex]$\frac{4}{3}\pi r^3$[/tex]      .......... (i)

Volume of cylinder = [tex]$\pi r^2h$[/tex]   ....................(ii)

Therefore, the ratio of sphere volume to cylinder volume is,

[tex]$\frac{4}{3}\pi r^3 : \pi r^2 h$[/tex]   ......(iii)

Divide both the sides by [tex]$\pi r^2$[/tex] , we get

[tex]$\frac{4}{3} \ r : h$[/tex]          ..........(iv)

We know that the height of the sphere = diameter of the sphere

The diameter of the sphere is D = 2r

Also the sphere height = cylinder height

So, the height of the cylinder = 2r

Therefore, substituting the height of the cylinder as 2r that is represented as h in equation (iv) is given by :

[tex]$\frac{4}{3} \ r : 2r$[/tex]        .............(v)

Now dividing both the sides by 2r, we get

[tex]$\frac{2}{3} : 1$[/tex]   ..................(vi)

Thus for equation (vi), we see, sphere volume = [tex]$\frac{2}{3}$[/tex]  of the cylinder volume

∴  sphere volume = [tex]$\frac{2}{3}\times 54$[/tex]

                              = 36 meter cube

Thus, Amie should have multiplied 54 by [tex]$2/3$[/tex] .
