(1/2 + 3/2)² + (2/3 x 1/2)³
docker41 [41]

The result of the mathematical expression given as follows: (1/2 + 3/2)² + (2/3 x 1/2)³ is 5.59 or 5⅔.

<h3>How to calculate mathematical expressions?</h3>

According to this question, the following expression is given to solve: (1/2 + 3/2)² + (2/3 x 1/2)³

First, we solve the both parts as follows:

  • ½ + 3/2 = 2
  • ⅔ + ½ = 1..16

Next, we solve the exponential function as follows:

= (2)² + (1.16)³

= 4 + 1.59

= 5.59 or 5⅔

Therefore, the result of the mathematical expression given as follows: (1/2 + 3/2)² + (2/3 x 1/2)³ is 5.59 or 5⅔.

An airplane flies with a constant
lora16 [44]

Answer:

1 hour and 30 minutes.

Here's how I did it:

960/3 = 220

220 = 30 minutes

220 = 30 minutes x 3 = 960

30x3=90

90 has to be converted into minutes and hours

so 90 = 1:30
