Of 130 patients in a hospital, 70% of them are checked in for the flu. How many patients are not checked in for the flu?

Answers

Answer 1

Answer: First let's find the number of patients checked in:
$x = (130)0.70 \n x = 91$
we know that 91 patients were checked in, so we can find how many were not:
$z = 130 - 91 \n z = 39$
39 patients were not checked in for the flu.

Answer 2

Answer:

39!

Explanation:

70% of 130 is 91

70 x 130/

100

= 91 you do 70 time 130 divided by 100 which gets you to 91 so that means 91 patience have the flu to find how many don't have the flu you subtract 130-91 that gives you 39!

The sum of fifteen and six times a number t is 81

Answers

well the sum is 15+6=21. then you must do 81-21=60. So your answer must be t=60.

We need to turn this phrase into an algebraic equation and then solve...

in math
"of" means times (x)
"is" means equals (=)
"sum" means you're going to add

The sum (we are going to add) of 15 and six times a number t (15 + 6t) is 81 (= 81). So write it out...

15 + 6t = 81

Now solve for t. First subtract 15 from each side...

15 + 6t - 15 = 81 - 15
6t = 66

Now divide each side by 6 to get t by itself...

6t/6 = 66/6

t = 11

What does x equal?

Answers

$12-x=15 \n \n -x = 15 - 12 \n \n -x = 3 \n \n x = -3 \n \n$

The final result is: x = -3.

Ok. First you isolate the variable. So Ill take 12 which is posotive, and subtract 12 from the 15 and the 12. Now all were left with is -x=3. We multiply each side by -1 to give us x=-3. Hope this helps!

What is the mass of the 2.5 kilogram in mass in grams

Answers

Answer:

2500g

Step-by-step explanation:

In the Metric Decimal System. Each subunit (to the left) is 10 times higher or 1/10 times lower .

1Kg 1hg 1dag 1g 1dcg 1cg 1 mg

1000g 100g 10g 1g 0.1g 0.01g 0.001g

From the scheme above, we have many relations. The one that answers the question is below followed by a rule of three:

1 kg----1000g

2.5kg-----x

x=2500g

1 kg= 1000g

So to go from kilograms to grams, multiply by 1000:
2.5kg*1000= 2500 g

Answer: 2500 g

at a checkers tournament there where 64 players. It was elimatation tournament. how many games where played before there was a winner

Answers

so first game
half were eliminated
we notice a pattern
first game=64 times 1/2
next game 32 times 1/2 so

so just multiply by 1/2 till you get 1
round 1 64/2=32
round 2 32/2=16
round 3 16/2=8
round 4 8/2=4
round 5 4/2=2
round 6 2/2=1

6 is the answer

There are 64 players. For each group, one person is eliminated. You will divide 64/2(the # of people is 64, the number op people in each group is 2). You will get 32. 32 people are remaining. You will, again, divide. 32/2=16. 16 people remain. Divide, again by 2. 16/2=8. Divide by 2 again until you get to 1.

hope this helps!
