Answer:
y=12
Step-by-step explanation:
12=24-y
step 1
subtract each side by 24
24-24 cancels out
12-24=-12
now we have
-y=-12
we now have to divide by -1
-1/-1=1
-12/-1=12
so we can conclude that y=12
Answer:
1.922 miles is equivalent to 3.1 kilometers.
Step-by-step explanation:
Given:
1 km = 0.62 miles.
3.1 km = ? miles
Now, in order to find the number of miles equivalent to 3.1 km, we use unitary method with the help of the conversion factor.
From the conversion factor, we can conclude that kilometer is a smaller unit compared to that of mile.
So, conversion factor = 
The formula to transform 'n' kilometers to miles is given as:
Therefore, 3.1 km = 
3.1 km =
miles
Therefore, 1.922 miles is equivalent to 3.1 kilometers.
Answer:
choice C. Perfect square trinomial is correct.
Step-by-step explanation:
We need to find the pattern which is represented by the polynomial
.
To find that pattern, we need to factor 





which is a perfect square.
Hence choice C. Perfect square trinomial is correct.
There are six digits. The first can be anything but 0. There are 9 other choices.
Are repetitions allowed? Is 999999 permitted.
Repetitions allowed.
9 * 10 * 10 * 10 * 10 * 5 The last digit must be odd.
450,000 <<<< answer.
No repetitions
Sorry this requires more thought.
So here we use the pythagorean theorem which is a2 + b2 = c2 (“a” squared times “b” squared equals “c” squared) the length from calvins house to the intersection is “a” and the length from phoebes house to the intersection is “b” so in order to find out the length of “c” (calvins house to phoebes house) we need to use the pythagorean theorem
a2 275x275=75,625
b2 113x113 = 12,769
so now that we have figured out what a2 and b2 are let’s add them
75,625 + 12,769 = 88,394
now since we only need to find out the length and not the area we need to find the square root of 88,394
the square root of 88,394 is 297.311 (i cut off the decimal after three places)
the direct length from phoebes house to calvins is 297.311 meters
