Answer:

Step-by-step explanation:

  • A(2,1)

2x-y+k=0    k=?

2*2-1+k=0

4-1+k=0

3+k=0

k=-3

  • B(5,-8)

2x-y+k=0

2*5-(-8)+k=0

10+8+k=0

18+k=0

k=-18

Answer:

  k = -8

Step-by-step explanation:

The location of P is ...

  P = (2A+B)/3 = (2·2+5, 2·1-8)/3 = (3, -2)

Putting this point into the equation for the line, we have ...

  2(3) -(-2) +k = 0

  8 +k = 0

  k = -8

C = 2 * pi * r

r is 1 yard

c = 2 * pi * 1 = 2pi yards = 6.3 yards

Answer:

Car: 60%

Motorcycle: 30%

Truck: 10%

Step-by-step explanation:

Car: \frac{12}{12+6+2} =\frac{12}{20} =\frac{60}{100} or 60%

Motorcycle: \frac{6}{12+6+2} =\frac{6}{20} =\frac{30}{100} or 30%

Truck: \frac{2}{12+6+2} =\frac{2}{20} =\frac{10}{100} or 10%

Shen picks a rational number.What is true about the opposite of his number?
Andreyy89
It is the same distance from 0 as the original number

a rational number is any number that can be written as a fraction.
lets say she picked 1/4...the opposite would be -1/4...both are equidistant from 0.

You want to put a 5 inch thick layer of topsoil for a new 23 ft by 17 ft garden. the dirt store sells by the cubic yards. how ma
Oksanka [162]
1 yard = 3 feet = 36 in

so 1 in = 1/36 yard,  1 ft = 1/3 yard.

The volume of the layer of the topsoil, is:

5 in * 23 ft * 17 ft = 5 *(1/36)*23*(1/3)*17*(1/3)  yard cubed =

(5*23*17)/(36*3*3)= 1955/324=6.034 yard cubed.


The store only sells increments of 1/4 = 0.25 cubic yards.


we need 6.034/0.25=24.136 


So we need to buy 25 (24 will not be enough) increments of 1/4 cubic yards.


Answer: 25 increments of 1/4 cubic yard, that is 25*0.25=6.25 cubic yards.
