Answer:

B

Step-by-step explanation:

Only 1 because

1/1 = 1

2/1 = 2

The answer can't be 0 because we can't divide by zero.

The answer can't be 2 because you can't divide 1 by 2 without having a number with decimal places

Same thing for the 4

Shalnov [3]
Each week he earns $142.5 from his partime job plus $25 from chores and then saves 85% of that total ($167.5). 85x167.5 = 14237.5 divided by 100 = 142.375 which is 85% of what he earns each week. Then multiply that by 8 weeks to find his total on August 25th. The answer should be $1,139

Find a basis for the orthogonal complement of the subspace of R4 spanned by the vectors. v1 = (1, 4, -5, 3), v2 = (4, 15, 0, 5),
Arlecino [84]

Answer:

W1 =  ( -75, 20, 1 , 0 )

W2 = ( 25, -7 , 0, 1 )

Step-by-step explanation:

attached  below is the remaining part of the solution

for a homogenous system of equation ; Ax = 0

x1 + 4x2 -5x3 + 3x4 = 0

-x2 + 20x3 -7x4 = 0         note: x3 and x4 are free variables

we can take x3 = 0 and x4 = 1 , hence ; x2 = -7

∴ x1 - 28 + 3 = 0 = x1 = 25

W2 = ( x1 ,x2, x3, x4 ) = ( 25, -7 , 0, 1 )

now lets take x3 = 1  and x4 = 0   hence x2 = 20 , x1 = -75

∴ W1 =  ( x1 , x2 , x3, x4 ) = ( -75, 20, 1 , 0 )

Pls help I’ll brainlest solve it like this
sergey [27]

\frac{3}{5} t = 6

t = 6 \div  \frac{3}{5}

t = 6 \times  \frac{5}{3}

t = 2 \times 5

t = 10

____________________________

\frac{1}{4} a =  \frac{14}{15}

a =  \frac{14}{15}  \div  \frac{1}{4}

a =  \frac{14}{15}  \times 4

a =  \frac{56}{15}
