Find the area of the shaded region. enter a decimal rounded to the nearest tenth

Answers

Answer:

78.42

Step-by-step explanation:

Area of 360 - 80 degree region.

You need to find out the region of the major arc where the circle is almost complete. The area left over will be calculated later

Angle = 360 -80

Angle = 280 degrees.

Area = [tex]\frac{angle*3.14*r^2}{360}[/tex]

Area = [tex]\frac{280*3.14*5^2}{360}[/tex]

Area = 23800/360

Area = 66.11

Area of the Triangle with sides of 5 cm each

Here's where I get into a bit of trouble. I have to assume you know some trig.

Find the height

Cos(40) = The height / the hypotenuse

Cos(40) =  h/5

0.7760 = h/5

h = 0.7760*5

h = 3.830

Find 1/2 the base (the chord of the circle)

Sin(40) = 1/2 base / hypotenuse

Sin(40) =  1/2 b / 5                          Multiply both sides by 5

1/2 b = 5*sin(40)                              Find the sin(40)

1/2 b = 5*.6428                               Combine the right

1/2 b = 3.139                                    multiply by 2

b = 6.4278

Find the area of the triangle

Area = 1/2 b * h

b = 6.4278

h = 3.830

Area = 1/2 * 6.4278*3.830

Area = 12.31 cm^2

Total Area

12.31 + 66.11 = 78.42

Okay so 15 apples=37.5%. if we substract that 37.5% out of the full 100%, we get 62.50%. Meaning that Jessica has 62.70%.

Answer:

62.5%

Step-by-step explanation:

40-15=25 apples left

25 apples/40 total=5/8 or 0.625

Translating that to a percent, we get 62.5% of the total apples left

Timothy purchased a computer for $1000. The value of the computer depreciates by 20% every year.

Answers

Answer:

We can apply the straight-line method to solve for the value of the computer every year.

Step-by-step explanation:

Step one:

What is depreciation?

It can be defined as the loss of value of a commodity.

In this problem, the percent depreciation is given as 20% which means that 20% of the worth of the computer is lost every year.

We are told that the computer cost is $1000

let the number of years taken for the computer to depreciate be x

Step two:

Say we want to find the value of the computer after 1 year, the value of the computer will be

Value of computer= 1000-20/100*1000

Value of computer= 1000-0.2*1000

Value of computer= 1000-200

Value of computer= $800

Step three:

For the second year, the value will be

Value of computer= 800-20/100*800

Value of computer= 800-0.2*800

Value of computer= 800-160

Value of computer= $640

Answer:

This situation represents exponential decay. The rate of growth or decay, r, is equal to 0.2. So the value of the computer each year is 80% of the value in the previous year. It will take 3 years for the value of the computer to reach $512.

2. Lin’s family buys 2 adult tickets and 2 child tickets for $26. Mike’s family buys 2 adult tickets and 3 child tickets for $31. Which system represents the situation? PLEASE HELP , no one ever helps please if u do pls!

Answers

Answer:

the adult tickets are 8 dollars and they kid tickets are 5 dollars bc 8+8+5+5=26 and mike's family is 8+8+5+5+5=31 hopes this help so each adult ticket is 8 dollars and each kid ticket is 5 dollars

Step-by-step explanation:

hope this helps❤️

The cost of an adult ticket is $15.50 and the cost of a child ticket is $8.50
Proof:
Set up a system of equations calling Adults a and Children c
2a+3c= $56.50 (equation 1)
4c+a= $49.50 (equation 2)
a= -4c+49.50 (i subtracted 4c to both sides) (label equation 3)
sub equation 3 into equation 1
2(-4c+49.50)+3c= 56.50
-8c+99+3c=56.50
-5c+99=56.50
-99 -99
-5c = -42.50
c= -42.50/ -5
c= 8.50
sub c=8.50 into equation 3 to find adult price
a= -4(8.5)+49.50
a= 15.50

Therefore Child Cost = $8.50 and Adult Cost= $15.50
