Carrie is an american teaching english in mexico, and she currently has 45,000 pesos in her bank account. if the exchange rate changes from 1 u. s. dollar = 12.94 mexican pesos to 1 u. s. dollar = 13.09 mexican pesos, what happens to the value in u. s. dollars of the money in carrie's bank account?

Because of change in conversion rates, the value in Carrie's account decreases by $39.85.

Step-by-step explanation:

Total money in Carrie's bank account = 45000 pesos.

If exchange rate is 1 USD = 12.94 pesos, then in dollars the money in account is :

= $3477.588 ≈ $3477.59

If exchange rate is 1 USD = 13.09 pesos, then in dollars the money in account is :

= $3437.738 ≈ $3437.74

Now, if the conversion rate is 12.94 pesos then the amount in dollars is more, than when the conversion rate is 13.09 pesos.

The difference is dollars.

So, because of change in conversion rates, the value in Carrie's account decreases by $39.85.

2. angles qrt and qst both measures 156 degrees.

step-by-step explanation:  

we have been given a diagram of a circle and we are told that measure of arc qvt is 156 degrees.  

we can see from our given diagram that angle qrt and angle qst subtends to arc qvt.

since we know that angles subtended by the same arc at the circumference are always equal.

by angle subtended by same arc theorem, measure of angle qrt and angle qst will be equal to the measure of arc qvt.

therefore, angles qrt and qst both measures 156 degrees and 2nd statement is the correct choice.

$4034.40

the perimeter of the field is the sum of the lengths of the four sides:

47 yd + 158 yd + 47 yd + 158 yd = 410 yd

the cost of 3 ft (1 yd) of fence is 3×$3.28 = $9.84.

so the cost of jake's wood perimeter fance is

(410 yd) × ($9.84 /yd) = $4034.40
