Abicycle that costs $126 is discounted by 2/10 of its price. find the discounted price.

twenty six kilograms of strawberries are packaged evenly into five boxes.
a) how much does each box weigh?
b) if the strawberries cost $3 per kilogram, how much does one box cost?
show me how u got the answer and i need ! will mark as brainlest!

1.) $100.80

2A.) 5.2Kg

2B.) $15.60

Step-by-step explanation:

1.)

You'd first have to reduce 2/10 down to 1/5, then change it to a percentage, which is 20%.

Then you take 20% off of $126.

Discount = Original Price * Discount% / 100

So it'd be

D = 126 * 20 / 100

D = 2520 / 100

D = $25.20

Then, you'd have to take the discount off the original price to find the new price.

$126 - $25.20 = $100.80

2A.) To figure this out, you'd take the 26KG, and divide it into 5 packages.

26/5= 5.2.

2B.) If one box is 5.2/Kg, and it's $3/Kg, you'd simply take the packages' weight (5.2) and multiply that by $3

5.2 * 3 = $15.60

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
