30 points! The equation y=1.55x + 110,419 approximates the total amount, in dollars, spent by a household to raise a child in the United States from birth to 17 years, given the household’s annual income, x.
What is the approximate average yearly cost of raising a child in a household with an annual income of $33,000
Given:
The equation is
[tex]y=1.55x+110,419[/tex]
Here, y approximates the total amount, in dollars, spent by a household to raise a child in the United States from birth to 17 years, given the household’s annual income, x.
To find:
The approximate average yearly cost of raising a child in a household with an annual income of $33,000.
Solution:
We have,
[tex]y=1.55x+110,419[/tex]
Put x=33000 to get the total amount, in dollars, spent by a household if annual income of $33,000.
[tex]y=1.55(33000)+110,419[/tex]
[tex]y=51150+110,419[/tex]
[tex]y=161,569[/tex]
So, total amount spent by a household to raise a child in the United States from birth to 17 years is $161,569.
Divide this total amount by 17 to get the average yearly cost of raising a child in a household with an annual income of $33,000.
[tex]\dfrac{161,569}{17}=9504.05882353[/tex]
[tex]\dfrac{161,569}{17}\approx 9504.06[/tex]
Therefore, the average yearly cost of raising a child in a household with an annual income of $33,000 is $9504.06.
Answer:
yearly cost $9,504
Step-by-step explanation:
1.55(33,000)+110,419 =161,569
161,569/17= 9,504.058823529412

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?
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

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
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 degreeTrigonometric RatioThis is a geometric method used to find the side or angle of a right angle triangle.
The plane's ground horizontal distance from the airportTo 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) = yFrom 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 groundUsing 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.

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

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?
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.
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?
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.
