Which statement describes the ratio of weight to mass and the value of x in the table?
tiny-mole [99]
To find the ratio, pick any pair of corresponding table values.
  weight/mass = (196 N)/(20 kg) = 98/10 N/kg

You can find x from ...
  (98/10)x = 1078
  x = 1078*10/98 = 110

The appropriate choice is ...
  B   The ratio is 98/10; x = 110

7x + 1 by = 1/3<br> 2x + 2y = 28
sweet-ann [11.9K]
7x+1 = (1/3)
2x + 2y = 28

Systems of equations.
Solve equation with single variable first.
7x+1 = (1/3) , x = (-2/21)

Substitute the value of x in second equation and solve for y.
2(-2/21) + 2y = 28, y = (296/21)

I’m assuming that isn’t the correct answer because you wrote the first equation incorrectly.

Alex needs to varnish the top And the bottom of a dozen rectangular wooden planks planks are 8 feet long and 3 feet wide each pi
meriva

Answer:

It will cost approximately $16.12 to varnish all the wooden planks.                                            

Step-by-step explanation:

We are given the following in the question:

Number of rectangular planks = 12

Dimension of the rectangular wooden plank:

Length = 8 feet

Width = 3 feet

Area covered by I bottle of varnish = 125 Square feet

Cost of 1 bottle of varnish = 3.50 units

Area of 1 rectangular plot =

A = \text{Length}\times \text{Width}\\A = 8\times 3\\A = 24\text{ square feet}

Total area to be covered by varnish =

= \text{Area of 1 plank}\times 12\times \text{Top area and bottom area}\\=24\times 12\times 2\\=576

Number of varnish bottles required =

n = \dfrac{\text{Total area}}{\text{Total area covered by 1 varnish bottle}} = \dfrac{576}{125} = 4.608

Cost of varnishing =

=\text{Cost of 1bottle of varnish}\times \text{Number of varnish bottles}\\=4.608\times 3.50\\=\$16.12

Thus, it will cost approximately $16.12 to varnish all the wooden planks.
