Answer:

First one: 40%

Second one: 30%

Step-by-step explanation:

2/5 is equal to the fraction 4/10 which is also equivalent to 40/100

in a percentage that would be 40% of the dogs are poodles

 

to find a percentage divide numerator by demonimator and multiply by 100

so divide 12 by 40 and multiply by 100

12/40=0.3

0.4x100=30%

In how many different ways can a president vice-president and secretary be elected from a class of 15 students
PolarNik [594]
Answer: 2730

---------------------------------------------------------

Explanation:

A shortcut way is to start at 15 and count down til you reach three values. So that means you'll have 15, 14, 13 which multiplies out to...

15*14*13 = 2730

Or you can use the nPr formula, with n = 15 and r = 2, to get the same answer

nPr = (n!)/((n-r)!)
15P3 = (15!)/((15-3)!)
15P3 = (15!)/(12!)
15P3 = (15*14*13*12!)/(12!)
15P3 = 15*14*13
15P3 = 2730

Hmmmm, it's either B or C, but I think B is closer related to a genre, so I think the answer is C, it has to do with the story's settings! :)

Fingers crossed that I helped!

Answer:

Hence first graph is the correct answer.

T I

1 28

2 56

3 84

4 112

Step-by-step explanation:

Given that initial amount P = $400

Simple rate of interest = R = 7% = 0.07

Time t= 1,2,3,4 years.

Then apply Simple interest formula to find the total interest earned in the given years.

I=PRT

for t=1 year

I=PRT=400(0.07)(1)=28

for t=2 year

I=PRT=400(0.07)(2)=56

for t=3 year

I=PRT=400(0.07)(31)=84

for t=4 year

I=PRT=400(0.07)(4)=112

Now we have table as shown below:

T I

1 28

2 56

3 84

4 112

Graphing these points we see that obtained graph best matches with First choice .

Hence first graph is the correct answer.

laila [671]
Splashtown: 25 + 1x
Schlitterbahn: 40
25 + 1x = 40
-25 -25
0 1x = 15
x = 15
So after 15 rides, Schlitterbahn would be cheaper than Splashtown.
