Answer:

Distance cover by Alyson = 16 miles

Step-by-step explanation:

Given:

Distance cover together = 39 miles

Assume;

Distance cover by Jeff = a

Distance cover by Alyson = a - 7

Find:

Distance cover by Alyson

Computation:

a + (a - 7) = 39

2a - 7 = 39

2a = 46

a = 23

Distance cover by Alyson = a - 7

Distance cover by Alyson = 23 - 7

Distance cover by Alyson = 16 miles

There is probability of 33%.

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.

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 )

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:

1 + 3i

Step-by-step explanation:

1(2+i)+i(2+i)

1*2+1i+i(2+i)

1*2+1i+2+ii

2+i+2i-1

1+i+2i

1+3i

Multiplication is the process of multiplying. The product (1+i)(2+i) is (1+3i).

Multiplication is the process of multiplying, therefore, adding a number to itself for the number of times stated. For example, 3 × 4 means 3 is added to itself 4 times, and vice versa for the other number.

The product (1+i)(2+i) can be done as,

(1+i)(2+i)

= 2 + i + 2i + i²

= 2+ 3i -1

= 1+3i

Hence, the product (1+i)(2+i) is (1+3i).

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

The x-intercept is given by the coordinates as (x, 0)

i,e y = 0

The y-intercept is given by the coordinates as (0, y)

i.e x = 0

The x-intercept of the graph of 3x + 2y = 20 is at x = 20/3

The y-intercept of the graph of 3x + 2y = 20 is at y = 10

The coordinates in a graph indicate the location of a point with respect to the x-axis and y-axis.

The coordinates in a graph show the relationship between the information plotted on the given x-axis and y-axis.

We have,

3x + 2y = 20

The x-intercept is given by the coordinates as (x, 0)

i,e y = 0

The y-intercept is given by the coordinates as (0, y)

i.e x = 0

Now,

3x + 2y = 20

Putting x = 0 in (1) we get the y-intercept.

3x + 2y = 20

3x0 + 2y = 20

0 + 2y = 20

2y = 20

Divide both sides by 2.

y = 20/2

y = 10

Putting y = 0 in (1) we get the x-intercept.

3x + 2y = 20

3x + 2 x 0 = 20

3x + 0 = 20

3x = 20

Divide both sides by 3.

x = 20/3

Thus,

The x-intercept of the graph of 3x + 2y = 20 is at x = 20/3

The y-intercept of the graph of 3x + 2y = 20 is at y = 10

Answer: what is the question

Step-by-step explanation:

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:

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.
