Answer:
It would take her 90 minutes to run 10 miles.
Step-by-step explanation:
First you should divide 54 by 6 and you'll get 9. So it takes her 9 minutes to run 10 miles (which is physically impossible). You multiply 9 times 10 and get 90.
Answer:
The possible number of trees in each of the rows could be any amongst the following numbers;
1,2, 5 and 10
Step-by-step explanation:
Here, we want to know the possible common number of trees in each rows
For the girls, we have 30 trees
For the boys we have 50 trees
What we simply do here is to get the factors of both;
That will be listed as follows;
for 30;
1,2,3,5,6,10,15 and 30
for 50,
1, 2 , 5,10, 25 and 50
So the possible number of trees in each of the rows are;
1, 2 , 5 and 10
For the
problems presented, the answer would be the following:
1. Givens
are:
Θ – 25 degrees
<span>µ = 0.27 </span>
g = acceleration due to
gravity = 9.8 m/sec^2
Answer
would be <span>a = 2.14 m/sec^2.</span>
2. Givens are:
<span>N = 257.32 newtons </span>
<span>f = 0.27(257.32) </span><span>
<span>f = 69.48
N </span></span>
Answer would be <span>a = 2.80 m/sec^2 </span>
I am hoping that these answers have satisfied your queries
about these specific questions.
Let x% be the salt concentration of first solution.
Then in 8ml, amount of salt =
Given that to this 8ml solution, 11ml solution of a 47% salt solution is mixed.
amount of salt in 11ml of 47% salt solution is =
So, total amount of salt in new mixture =
But given that this new solution is a 43% salt solution.
Hence amount of salt in new mixture of (8+11)=19ml solution of 43% salt solution is
Hence
8x+517 = 817
8x=817-517 = 300
x= 300/8 = 37.5
Hence the salt concentration in the first solution is 37.5%
