each evening, Marisol spend at least twice as much time reading as she spends doing homework. If Marisol works on her homework for 42 minutes, how much time can she spend reading?

Answers

To get the result we can use knowledge that reading is 2 times longer than HW.
To find this value we just have to multiply 42 times 2 so
40*2=80
Its 1 hour and 20 min - its the result

multiply 42 times 2 and your answer will be 84

An enrolling high school student has the following subjects to open to her: English 5 ( section B or C)
Math 5 ( Section F,G or X)
History 5 (section T,U or Y)
Biology 1 ( section D,H,V or W)
if she will enroll in all of these subjects, in how many ways can she arrange her schedule?

Answers

so we notice that they increase by 1
each time
first slot we have all of them so
4 choices=1st slot
3 choices=2nd slot (1 was taken for 1st slot)
2 choices
1 choice
multiply
4 times 3 times 2 times 1=24
answe ris 24 ways

From the other answer, I see that my colleague with the busted clock
interpreted your question in a different way. So I should explain
how I understand your question.

I understand you to say that both English sections meet at the
same time, all 3 math sections meet at the same time, all 3 History
sections meet at the same time, and all 4 Biology sections meet at
the same time. So our student will take the subjects in that order,
but for each period, she can choose which section to join.
If that's not the right way to understand the question, then it's definitely
too complicated for me.

Reading it MY way,
here's the solution:

English: 2 choices. For each of those . . .
Math: 3 choices. For each of those . . .
History: 3 choices. For each of those . . .
Biology: 4 choices.

Total possible different line-up of sections:

(2 x 3 x 3 x 4) = 72 different line-ups.

The number of students at Marita's high school decreased to 98% of last year's number. Currently, there are 1,170 students. How many students were there last year? Round to the nearest number

Answers

Answer:

1193

Step-by-step explanation:

If the number of students decreased to 98% of last years total, the total students decrease by:

$100-98=2$

The amount of students decreased by 2% from the previous years total. We can then determine the amount of students that we 2% of the current total. We first convert 2% into a fraction:

$2/100=1/50$
