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 )

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

Answer:

B

Step-by-step explanation:

30 % of the total does Leah have.

percentage, a relative value indicating hundredth parts of any quantity.

Given,

Leah wants to buy a necklace for her mother's birthday that costs $48.50.

Leah has currently $14.55.

We need to find 14.55 is what percentage of 48.55.

Let x be the percentage.

48.55x=14.55

Divide both sides by 48.55

x=14.55/48.55

x=0.299

Now multiply with 100

x=0.299×100=29.9

x=30%

Hence, 30 % of the total does Leah have.

Answer:

(6,2) y-coordinate is 2

Step-by-step explanation:

The coordinates of the point F on directed line segment AB that partitions AB in the ratio 3 :2 are: (6, 2)

The formula for finding the coordinates of a point that divides the line in ratio m:n are given by:

We are given that Point A (3,-4) and Point B (8,6) on directed line segment AB.

Here (x1,y1) and (x2,y2) are coordinates of the two points line passed through

(x1,y1) = A(-3,-4)

(x2,y2) = B(8,6)

Ratio: 3 : 2

m = 3

n = 2

Putting the values in the formula

( x, y) = (3 x 8 + 2 x 3 /5  , 3 x 6 + 2 x (-4) /5 )

( x, y) = (24 + 6 / 5 , 18 - 8 /5)

( x, y) = (30/5, 10/5)

( x, y) = (6, 2)

Hence,

The coordinates of the point F  are: (6, 2)

Answer:

The fully shaded notes are called whole notes. The note that is not shaded in is called half notes.

Step-by-step explanation:

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.

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).
