The answer to the question
Answer:
0.28277
I got this by plugging in 0.2512 for "A" ( A = π r² ) Then I solved the rest ( divide both sides by pie, then taking the square root from that.
Step-by-step explanation:
Cos Milky Said it.
Given that a car averages 32 miles per gallon of gasoline.
That means in 1 gallon of gasoline, car will travel 32 miles.
Now we have to find the distance travelled by car in one fluid ounce of gasoline.
We know that 1 US liquid gallon = 128 US fluid ounce
So that means car travels 32 miles in 128 fluid ounce of gasoline
So to find the distance travelled by car in one fluid ounce of gasoline, we just need to divide 32 miles by 128
Hence answer will be 32/128 or 0.25 miles.
Answer:
3 patients had all the three complaints
Step-by-step explanation:
Let U be the set of patients who reported at the hospital on that day
Let F be the set of patients who complained of fever
Let S be the set of patients who had stomach troubles
Let I be the set of injured patients
Then the given data can be written as:
- n(U) = n(F∪S∪I) = 100
- n(F) = 70
- n(S) = 50
- n(I) = 30
- n(F∩S) + n(S∩I) + n(I∩F) - 3×n(F∩S∩I) = 44
n(F∩S∩I) = ?
Using the formula for the cardinal number of union of three sets:
n(F∪S∪I) = n(F) + n(S) + n(I) - n(F∩S) - n(S∩I) - n(I∩F) + n(F∩S∩I)
100 = 70 + 50 + 30 - (44 + 3×n(F∩S∩I)) + n(F∩S∩I)
100 = 150 - 44 - 2×n(F∩S∩I)
2×n(F∩S∩I) = 106 - 100 = 6
<u>n(F∩S∩I) = 3</u>
The first one we see that the intersection is 3 units to the right and 6 uniits down or x=3 and y=-6 (down=-) so the point is (3,-6)
the solutions (1,2)
we subsitute and find that the answer is the first equation
we add them together and get
we negative the first and add
-2x+2x+y+y=5+5
2y=10
y=10
sutaitute
2x-y=-5
2x-10=-5
we can see that there is 1 solution
