Answer:

There is probability of 33%.

Answer: 17 cm

Step-by-step explanation:

For a regular figure where the area of the base is B, and the height is H, the volume is calculated as:

V = B*H

Here we know that the base of the prism is B = 3 cm^2, and the volume of the prism is 51 cm^3

Then:

B = 3cm^2

V = 51cm^3

If we replace those in the equation above, we get:

51 cm^3 = (3cm^2)*H

Solving this for H gives:

(51 cm^3)/(3 cm^2) = H = 17 cm

The height of the tubing is 17 cm

Answer:

15%

Step-by-step explanation:

1. Subtract final value from starting value

65 - 55.25 = 9.75

2. Divide 9.75 by original number

9.75/65 = 0.15

3. Multiply quotient by 100 to get percentage

0.15 x 100 = 15%

Answer:

Not a function

Step-by-step explanation:

x repeats, you have 5 mapped to 1 and 5 mapped to 9 so you have to have a one-to-one relationship with your points if it is a function

Answer:

Step-by-step explanation:

Remark

Unless you know calculus, the only way to solve this is by completing the square.

Solution

y = 4x^2 + bx - 2

y = 4(x^2 + b/4 ) - 2

y = 4(x^2 + b/4 + (1/2b/4)^2 ) - 2 - 4*(b/8)^2

y = 4(x^2 + b/4 + (b/8)^2 ) -  2 - b^2/16

y = 4(x + b/8)^2 - 2 - b^2/16

Now what you want to happen is to give b/8 a value of 1 so that when x is put in -1 you get 0 for  what is inside the brackets.  

b/8 = 1

b = 8

y = 4(x + 1)^2 - 2 - (8)^2 / 16

y = 4(x + 2)^2 - 2 - 4

y = 4(x + 1)^2 - 6

The vertex is at (-1, - 6)

The axis of symmetry  is x = - 1

Note

This could have been done a lot shorter just by realizing that the number inside the brackets had to be + 1 as in (x + 1). But then you would not have been able to know the minimum value for y which is - 6

Answer:

They made 132$, and 66 slices were sold.

Step-by-step explanation:

If all of the pies were cut into six pieces, and each piece costed $2, then you can multiply 6 x 2 to determine how much each pie cost. ($12)

If each pie costed $12 and there were 11 pies sold in total, then you can multiply 12 x 11 to find out how much money they made.

And to find out how many slices they sold you just have to multiply the 11 total pies by 6 because each pie had six pieces.

Answer:

x = 4[tex]\sqrt{6}[/tex] , y = 8[tex]\sqrt{2}[/tex]

Step-by-step explanation:

Using the sine ratio in the right triangle on the left and the exact value

sin45° = [tex]\frac{\sqrt{2} }{2}[/tex]

let the altitude of the outer triangle be h ( common to both right triangles )

sin45° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{h}{8}[/tex] = [tex]\frac{\sqrt{2} }{2}[/tex] ( cross- multiply )

2h = 8[tex]\sqrt{2}[/tex] ( divide both sides by 2 )

h = 4[tex]\sqrt{2}[/tex]

----------------------------------------------------------------

Using the tangent ratio in the right triangle on the right and the exact value

tan30° = [tex]\frac{1}{\sqrt{3} }[/tex] , then

tan30° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{h}{x}[/tex] = [tex]\frac{4\sqrt{2} }{x}[/tex] = [tex]\frac{1}{\sqrt{3} }[/tex] ( cross- multiply )

x = 4[tex]\sqrt{6}[/tex]

--------------------------------------------------------------------

Using the sine ratio in the right triangle on the right and the exact value

sin30° = [tex]\frac{1}{2}[/tex] , then

sin30° = [tex]\frac{h}{y}[/tex] = [tex]\frac{4\sqrt{2} }{y}[/tex] = [tex]\frac{1}{2}[/tex] ( cross- multiply )

y =8[tex]\sqrt{2}[/tex]

Answer: what is the question

Step-by-step explanation:

Answer:

The missing leg's measurement is 8.

Step-by-step explanation:

[tex]a^{2} +b^{2} =c^{2}[/tex]

[tex]a^{2}+15^{2} =17^{2}[/tex]

[tex]a^{2}[/tex]+225=289

[tex]a^{2}[/tex]=64

a=√64

a= 8

Hope this helps! :)

Answer:

The length of the missing side is 8.

Step-by-step explanation:

to find the missing side, use the following formula:

[tex]a^{2} = c^{2} - b^{2}[/tex]

(c = hypothenuse) (a and b = sides) ( a = missing side)

[tex]a^{2} = 17^{2} - 15^{2}[/tex]

[tex]a^{2} = 289 - 225[/tex]

[tex]a^{2} = 64[/tex]

[tex]\sqrt{a^{2} } = \sqrt{64}[/tex]

a = 8

Answer:

25.37

Step-by-step explanation:

Use SOH or Sin∅=[tex]\frac{opposite}{hypotenuse}[/tex]

So Sin(70)= [tex]\frac{x}{27}[/tex]

Multiply both sides of the equation to end up with 27Sin(70)=x

Plug into your calculator in degrees and you get 25.37m

Step-by-step explanation:

Answer:

336 ft²

Step-by-step explanation:

The figure is composed of a rectangle and a right triangle

A of rectangle = length × breadth = 24 × 12 = 288 ft²

A of Δ = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the perpendicular height )

Here b = 32 - 24 = 8 ft and h = 12 , then

A of Δ = [tex]\frac{1}{2}[/tex] × 8 × 12 = 4 × 12 = 48 ft²

composite area = 288 + 48 = 336 ft²

Answer:

$10.50

Step-by-step explanation:

Interest = future value - amount saved

The formula for calculating future value:

FV = P (1 + r)^n

FV = Future value  

P = Present value  

R = interest rate  

N = number of years

$50 x (1.1)^2 = $60.50

Interest = $60.50 - $50 = $10.50

Answer:

3.08 hours

Step-by-step explanation:

Preparation for the homecoming football game, members of the student body are painting the spirit rock in front of the school.

If Angela works alone, it will take her five and a half hours.

If Brandon works alone, it will take him 7 hours. If they work together, it will take them approximately hours ?

This is calculated as:

The Number of hours they worked together = T

1/5.5 + 1/7 = 1/T

= 7 + 5.5/(5.5)(7)

= 12.5/38.5

1/T = 12.5/38.5

Cross Multiply

12.5T = 38.5

T = 38.5/12.5

T = 3.08 hours

The time required when Angela and Brandon work together, for the preparation for the homecoming football game, is 3.08 hours.

The total time taken is inversely proportional to the rate of work. If a unit of work is done in total n number of days, then the total work done in a day can is,

[tex]W_1=\dfrac{1}{n}[/tex]

In preparation for the homecoming football game, members of the student body are painting the spirit rock in front of the school.

If Angela works alone, it will take her five and a half hours. The work done by Angela in one hour is,

[tex]A=\dfrac{1}{5.5}\\A=\dfrac{2}{11}[/tex]

If Brandon works alone, it will take him 7 hours. The  work done by Brandon in one hour is,

[tex]B=\dfrac{1}{7}[/tex]

The work done in one hour, when the work together,

[tex]A+B=\dfrac{2}{11}+\dfrac{1}{7}\\A+B=\dfrac{14+11}{77}\\A+B=\dfrac{25}{77}\\A+B=\dfrac{1}{3.08}[/tex]

Thus, the time required when Angela and Brandon work together, for the preparation for the homecoming football game, is 3.08 hours.
