In a jewelry store, rings make up 5\9 of the inventory.Earrings make up 4\15 of the inventory .How many times greater is the ring inventory Than the earring inventory?

Answers

Answer:

2.083 times

Step-by-step explanation:

Given that:

Rings = 5/9 of inventory

Earrings = 4 /15 of inventory

How many times greater is the ring inventory Than the earring inventory?

To obtain the number of times ring inventory is greater than earring inventory:

Divide the fraction of inventory in ring / fraction of earring inventory

5/9 ÷ 4/15

5/9 * 15/4

= 5*15 / 9*4

= 75 / 36

= 2.083

Hence, ring inventory is 2.083 times more than earring inventory.

Mr.Cunningham built himself an ice rink that is 14 and 2/5 meters long and 6 and 7/8 meters wide. What is the area of the ice rink Mr.Cunningham built?

Answers

Answer: 99 sq., meters.

Step-by-step explanation:

Given: For ice rink, Length = [tex]14\dfrac25\text{meters}=\dfrac{14\times5+2}{5}=\dfrac{72}{5}\text{meters}[/tex]

Width = [tex]6\dfrac78\text{meters}=\dfrac{8\times6+7}{8}=\dfrac{55}{8}\text{meters}[/tex]

Now, Area of ice rink = length x width

[tex]=\dfrac{72}{5}\times\dfrac{55}{8}=\dfrac{9}{1}\times\dfrac{11}{1}=99\text{ sq. meters}[/tex]

Hence, the area of the ice rink Mr.Cunningham built = 99 sq., meters.

The bill for fixing a car was $436. The parts cost $176 and the repair center charged
$52 per hour. How many hours did it take to fix the car?

Answers

Answer:

5 hours

Step-by-step explanation:

The bill for fixing the car is $436

The parts cost $176

The repair center charged $52 per hour

Therefore the hours that it took to fix the car can be calculated as follows

= $436-$176

= $260/52

= 5 hours

Hence it will take 5 hours to fix the car

What is the difference of (5 + 3i) and (2 + 9i)?

Answers

Step-by-step explanation:

(5+3i)-(2+9i)

= 5 +3i - 2 -9i

= 5-2 +3i -9i

= 3 -6i

= 3( 1- 2i) [ 3 is taken as common]

this is the answer

The difference of (5 + 3i) and (2 + 9i) would be;  3( 1- 2i).

What are complex numbers?

Complex numbers are those numbers that contain the imaginary and the real part. Complex value z is written in a rectangular form as z = x+iy where (x, y) is the rectangular coordinates.

WE are asked to find the difference between (5 + 3i) and (2 + 9i).

Thus, (5+3i)-(2+9i)

= 5 +3i - 2 -9i

= 5-2 +3i -9i

= 3 -6i

= 3( 1- 2i) [ 3 is taken as common]

Therefore, the difference of (5 + 3i) and (2 + 9i) would be;  3( 1- 2i).

When a 757 passenger jet begins its descent to the Ronald Reagan National Airport in Washington, D.C., it is 3900 feet from the ground. Its angle of descent is 6 degrees

Answers

Answer:

Step-by-step explanation:

The plane's horizontal distance from the ground is 409.91 ft and the plane must fly 37310.411 ft before it descends to the ground.

Data;

Distance of the place from the ground = 3900 ftangle of depression = 6 degree

Trigonometric Ratio

This is a geometric method used to find the side or angle of a right angle triangle.

The plane's ground horizontal distance from the airport

To find the plane's ground distance from the airport, we have to use trigonometric ratio

The plane distance from the ground (opposite) = 3900The angle = 6 degreeThe plane's horizontal distance from the ground (adjacent) = y

From SOHCAHTOA

Using tangent of the angle

[tex]tan \theta = \frac{opposite}{adjacent}\\ tan 6 = \frac{3900}{y}\\ \\y = 37106.02ft[/tex]

The plane's horizontal distance from the ground is 409.91 ft.

How far must the plane fly before it descend to the ground

Using the values above,

Taking the sine angle of this since we have the value of angle and opposite.

[tex]sin\theta = \frac{opposite}{hypothenuse}\\ sin6 = \frac{3900}{x}\\ x = \frac{3900}{sin6}\\ x = 37310.411ft[/tex]

The plane must fly 37310.411 ft before it descends to the ground.
