Answer:

1. add up all of the arcs.

2x+3x+4x-8+x-12

2. all of the arcs equal 360

2x+3x+4x-8+x-12=360

3. Find x

10x-20=360, x=38

4. angle LTE is equal to half of the sum of the intercepted arcs.

.5(arc LE +GF)

5. plug in LE +GF with x

.5(76+144)

LTE=110

What is the surface area of a cone with a slant height of 12.5m and a diameter of 9m? Round to the nearest whole number.
notka56 [123]

9514 1404 393

Answer:

  240 m²

Step-by-step explanation:

The lateral surface area is given by the formula ...

  LA = πrs . . . . . cone with radius r and slant height s

The base area is given by the formula ...

  BA = πr²

The total surface area is the sum of these:

  SA = BA +LA = πr² +πrs = πr(r+s)

The radius is half the diameter, so is 9m/2 = 4.5 m. Then the surface area is ...

  SA = π(4.5 m)(4.5 m +12.5 m) = 76.5π m² ≈ 240 m²

73. Suppose that you want to buy a house that costs $175,000. You can make a 10% down payment, and 1.2% of the house’s value is
Irina-Kira [14]

Answer:

total monthly payment is  $973.03

Step-by-step explanation:

given data

costs = $175,000

down payment = 10%

house value paid = 1.2%

to find out

monthly payment for a 30 year i.e 360 months

solution

we consider here rate of interest for 30 year is 4.25% so monthly interst rate will be \frac{0.0425}{12} = 0.00375

so We have present value Ap = 0.9 ( 175000) = $157500

and the monthly escrow payment is

monthly escrow payment = \frac{1}{12} × 0.012 × 175000

monthly escrow payment = $175

so  monthly payment formula is

monthly payment = \frac{Ap*r}{1-(1+r)^{-n}}   ..................1

here r is rate and n is time period

so

monthly payment = \frac{157500*0.00375}{1-(1+0.00375)^{-360}}

monthly payment  = 798.03

so the payment to the loan is $798.03 each month

and Then the total monthly payment is  = $798.03 + $175

total monthly payment is  $973.03

a living room measures 24 feet by 15 feet an adjacent square dining room measures 13 feet on each side if carpet cost 6.98 per s
Rina8888 [55]
Start by finding how many squares in both rooms are. 24 • 15 = 360 and 13 • 4 = 52 (since it is a square room multiply by 4) Now add. 360 + 42 = 412. Now multiply : 6.98 • 412 = 2875.76. The total cost of carpet for both rooms is $2875.76. Hope I helped!
