CONSTRUCTED RESPONSE II. Courtney adds 2 dimes, 3 quarters, and
6 nickels into a money jar. Courtney then
takes out 2 quarters and 5 dimes the next
day. Write an expression that shows how.
the overall amount of money in the jar
Increased or decreased. Then simplify
the expression.

the simplified form is

step-by-step explanation:

we want to simplify the expression,

let us change the middle bar to a normal division sign to obtain,

we multiply the first fraction by the reciprocal of the second fraction to obtain,

we factor to obtain,

we cancel the common factors to get,

we simplify to get,

the correct answer is b

answer: cos [   arcsin (3/5) - arccos (1/2) ] =

step-by-step explanation: × = 3/5 = 0.6--> x = 36.87 and x = 180 - 36.87 = 143.13 deg

cos y = 1/2 --> y = +- 60 deg a. cos (x - y) = cos (143.13 - 60) = cos 83,13  

=

0.12

b. cos (36.87 - 60) = cos (-23.23) = 0.92

answer: can you show the options ?

step-by-step explanation:

< 4 = < 5 they are vertical angles

120 degrees
