Answer:
Step-by-step explanation:
Given that:
and
If we equate both since they are distances, we have:
Algebraically, moving the equation to the right side, we get:
To factor the equation on the left side:
Factor out 2 on the left-hand side:
To determine the time when the two boats have to cover an equal distance:
Thus:
Answer:
10 > v (if you don't trust me, check it yourself. Subsitute v for 10 in the first equation.
Step-by-step explanation:
1) 7 > v - 3
2) add 3 to both sides
3) so 7 plus 3 equals 10
So you basically do this
7 > v - 3 (ad 3 to both sides)
You get 10 > v (which is as simplified as possible)
Hope this helps! :)
Answer:
32
Step-by-step explanation:
6% of 530
= 6% x 530
= 6/100 x 530
= 3180/100
= 31.8
31.8 ≈ 32
Triangularizing matrix gives the matrix that has only zeroes above or below the main diagonal. To find which option is correct we need to calculate all of them.
In all these options we calculate result and write it into row that is first mentioned:
A)R1-R3
B)2R2-R3
C)-2R1+R3
D)2R1+R3
E)3R1+R3
None of the options will triangularize this matrix. The only way to <span>triangularize this matrix is
R3-2R1
</span>
<span>
This equation is similar to C) but in reverse order. Order in which rows are written is important.</span>
The correct question is
<span>A country's people consume 6.3 billion pounds of candy (excluding chewing gum) per year. Express this quantity in terms of pounds per person per month. Note that the population of the country is 301 million.
we know that
1 billion------------------> 1000000000 </span><span>(Thousand </span>Million)=1 x 10<span>^9
</span><span>then
</span>6.3 billion pounds--------------> 6.3 x 10^9 pounds
[pounds of candy per person per year]=[6.3 x 10^9 pounds]/[301 x 10^6]
[pounds of candy per person per year]=20.93 pounds per person per year
[pounds of candy per person per month]=20.93/12=1.74 pounds per person per month
the answer is 1.74 pounds per person per month
