The sum of two numbers is 100, the difference between the two numbers is 26. What is the number that is less?

1 answer:

6 0

The numbers that would be smaller would be the two with the difference of 26.
27-1=26 where as, if you were to use a 1 in each, 99+1= 100. Therefore 27 and 1 (28) is less than 99 and 1 (100).

Find the vector reciprocal to set. a= i+2j+2k, b= 2i+3j+k, c= i-j-2k

inn [45]

Answer:

I just do a' as a sample. You calculate b' and c'

Step-by-step explanation:

$a'=\frac{b\times c}{a\bullet (b\times c)}, b' = \frac{c\times a}{a\bullet (b\times c)}, c' = \frac{a\times b}{a\bullet (b\times c)}$

Now, calculate b x c

$\left[\begin{array}{ccc}i&j&k\\2&3&1\\1&-1&-2\end{array}\right] =$

$a'=\frac{}{\bullet }=\frac{}{-5} =$

Answer:

x = 466.7 ft

Step-by-step explanation:

The lower angle in the right triangle = 31° ( alternate angle )

Using the cosine ratio in the right triangle, with hypotenuse x

cos31° = $\frac{adjacent}{hypotenuse}$ = $\frac{400}{x}$

Multiply both sides by x

x × cos31° = 400 ( divide both sides by cos31° )

x = $\frac{400}{cos31}$ ≈ 466.7
