Answer:

OPTION C: 60%

Step-by-step explanation:

Chances of raining the next day + Chances that it will not rain = 100%

One of them should definitely be true.

So, if the chance of it raining tomorrow is 40% then there is 60% chance that it will not rain tomorrow.

This can also seen as follows:

Probability of rain tomorrow + Probability of no rain = 1

Given Probability of rain tomorrow = 40% = $ \frac{40}{100} = \frac{2}{5} $

Probability of no rain tomorrow = 1 - Probability of rain tomorrow

⇒ Probability of no rain = 1 - $ \frac{2}{5} $

⇒ Probability of no rain = $ \frac{3}{5} $

Expressing it as percentage: $ \frac{3}{5} \times 100 $ = 60%.

Austin is serving his child french fries and chicken wings for lunch today. Let be the number of french fries in the lunch, and
seropon [69]

Answer:

25f+100c<500

Step-by-step explanation:

He wants that total calorie count to be less than 500 cals, so we use <.

25f, means for each french fries we have 25 calrs.

100c, for each chicken wings we have 100 calories.

So inequality is 25f+100c<500.

For example, he can not eat 4 french fries and 4 wings (4*25+100*4=500 is not less from 500, it is equal), but he can eat 3 fries and 4 wings (3*25+100*4=475<500).
