At 30 degrees, Edgardo said the temperature was warm enough to go swimming. Did he mean to give the temperature in Fahrenheit or Celsius. Explain.

Answers

30 Fahrenheit is just below the typical freezing temperature of water. 30 Celsius is just a few degrees below normal body temperature . . . nice for casual swimming. Edgardo might also have been referring to 30 degrees latitude.
Certainly in Celsius, because this temperature in Fahrenheit is a low temperature

If one honeybee makes 1/12 teaspoon of honey during its lifetime, how many honeybees are needed to make 1/2 teaspoon of honey

Answers

In this case we have to have a common denominator in order to compare to the two fractions.
(1)/(2) = (x)/(12) We know that 2 × 6= 12 
So multiply the numerator and denominator by 6
(1)/(2) × (6)/(6) = (6)/(12)
Therefore, the amount of honey needed is (6)/(12) teaspoons
So in total 6 bees are needed to make (1)/(2) teaspoons of honey because we know that (6)/(12) is the same as half

Your realized income is $36,864.00/yr. Your fixed and housing expenses are 32% and your savings are 15% of your realized income per month. How much discretionary money do you have, excluding savings, per month?

Answers

The discretionarymoney for a month is $1628.16, excluding savings per month.

What is discretionary money?

The discretionarymoney is the leftover money in the income after excluding the savings and expenditures.

Calculating the discretionary money for the given income:

The given realized income is $36,864.00/yr

Then for a month, the realized income = $36,864/12

                                                                = $3072/month

Fixed and housingexpenses are 32% of the realized income/month

= $3072 × (32)/(100)

= $983.04

Savings are 15% of the realized income/month

= $3072 × (15)/(100)

= $460.8

Then subtracting these from the realized income per month to get the discretionary money

Discretionarymoney (per month) = $3072 - $983.04 - $460.8

                                                        = $1628.16

So, the discretionarymoney left after excluding savings is $1628.16/month.

Answer:

You will have $1628.16 per month in discretionary money.

Step-by-step explanation:

In order to find the amount of money you have left for discretionary purposes at the end of the money, you need to calculate the total amount of your monthly pay is going towards expenses and savings.  Since there are 12 months in a year, your monthly income is $3072.  Of that amount, you spend 32% on housing and 15% on savings, for a total of 47%.  The remaining percentage of your income would be considered discretionary, which would account for 53%.  To find the amount of money, you take your monthly income and multiply it by 53%, or .53, which gives you $1628.16.

Mike observed that 75% of the students of a school liked skating. If 35 students of the school did not like skating, the number of students who liked skating was ______. (only put numeric values, no other symbols)

Answers

100-75=25% did not like
25%=35 students how about 75%
75 x 35 divided by 25=105 students 
105
100-75=25%
25%=35 students but you have 75%
so 75*30divided by 25=90 students
