Home price is $245,000. There is no down payment mentioned. 
I understand 20/4 as amortized over 20 years and balloon payment after 4 years.

Total cost would be =  Balloon payment + Total monthly payment 

4 years x 12 months = 48 months
Balloon payment =       216,789.79 x 1 mo =   216,789.79
Total monthly payment = 1,727.11 x 47 mos =  81,174.17

Total cost = 216,789.79 + 81,174.17 = 297,963.96

A light aircraft travels 5 miles per hour less than twice the speed of a bus. If the bus can travel 114 miles in the same time i
Rufina [12.5K]
A represents the speed of the aircraft.
b represents the speed of the bus.

a=2b-5
114/b=218/a

Substitution method

114/b=218/(2b-5)

(2b-5)*(114/b)= 218

(228b-570)/b = 218

228b-570= 218b

228b-218b=570

10b= 570

b=57

Plug the value of b into one of the original equations.

a=2(57)-5
a=114-5
a=109

Final answer:
Average speed of plane= 109
Average speed of bus= 57

Alan is making a small sign in the shape of a triangle for his store. He wants the height of the triangle to be 4 inches. The ar
Step2247 [10]

Answer:

b < 9

Step-by-step explanation:

We are given the following in the question:

Height of triangle,h = 4 inches

Area of triangle =

A = \dfrac{1}{2}\times b\times h

where b is the base of the triangle and h is the height of the triangle.

The area of the triangular sign must be less than 18 square inches.

Thus, we can write the inequality:

A< 18\\\\\Rightarrow \dfrac{1}{2}\times b \times h < 18\\\\\Rightarrow b < \dfrac{18\times 2}{4}\\\\\Rightarrow b < 9

The above inequality is the required inequality that describes the possible base length of the triangular sign.
