Item 20 You have two loans, for 2 years each. The total interest for the two loans is $138. On the first loan, you pay 7.5% simp

Aliun [14]

Interest on first loan = 800*.075*2 = 120
so the interest on the second loan 
= 138-120 = 18 

using the simple interest formula: 
18 = P*.03*2 
P = $300

A baseball team has a 20-person roster. A batting order has nine people. How many different batting orders are there

Jobisdone [24]

Answer:

60,949,324,800

Step-by-step explanation:

We solve the above question using Permutation formula

The formula for Permutation =

nPr = n!/(n - r)!

Total Amount in a Set (n) = 20 persons

Amount in each Sub-Set (r) = 9 batting order

Hence:

20P9 = 20!/(20 - 9)!

= 60,949,324,800

Therefore, the different batting orders they would have are: 60,949,324,800

the relationship between altitude and the boiling point is linear.AT an altitude of 8300ft 8300 ft , the liquid

mojhsa [17]

Complete Question

The relationship between altitude and the boiling point is linear. At an altitude of 8300ft, the liquid boils at 194.23 ° F

At an altitude of 4200 ft , the liquid boils at 202.02° F.

Write an equation giving the boiling point b of the liquid, in terms of altitude a in feet . feet . What is the boiling point of the liquid at 2600ft

Answer:

The equation is $y = -0.001943x + 210.3569$

At 2600ft the temperature is $y = 205.3051 \ °F$

Step-by-step explanation:

From the question we are told that

The temperature at 8300ft is 194.23 ° F

The temperature at 4200 ft is 202.02° F

Generally the slope for this relationship is mathematically represented as

$m = \frac{ 202.2 - 194.23}{ 4200 - 8300}$

=> $m = 0.001943 ^o F / ft$

Generally the according to the point slope formula is

$y - y_1 = m(x -x_1 )$

=> $y - 194.23 = -0.001943 (x - 8300 )$

=> $y - 194.23 = -0.001943x + 16.1269$

=> $y = -0.001943x + 210.3569$

Now we are given from the question that x = 2600 ft

Then

$y = -0.001943(2600) + 210.3569$

=> $y = 205.3051 \ °F$
