So 20:4000=1:200
and 50:10000=1:200
reverse
1lb:200ft^2
100ft^2=0.5lb
needs to cover 26400ft^2
100 times 264=26400 so
0.5 lb times 264=132 lb needed for entire yard

Which of the following is a point-slope equation of a line that passes through the points (-1,4) and (8,-2)
dexar [7]

Answer:

y = (2/3)x + 4 2/3

Step-by-step explanation:

For reference, a linear function has an equation of y = mx + b

The first thing we're going to do is use the slope formula, \frac{y2-y1}{x2-x1} or rise over run. In this case that looks like:

(-2-4) - (8 - -1)

-2 -4 comes out to - 6, and the denominator comes out to 9.

6/9 is equal to 2/3, which is our m or slope value.

Next we want to find the b value, or our y-intercept. To do that we'll plug one of the points into the equation with our new-found slope:

4 = (2/3)-1 +b

4 = -2/3 + b

4 2/3 = b

That means our complete equation is:

y = (2/3)x + 4 2/3

OR

y = (2/3)x + 14/3 (equivalent but an improper fraction rather than a mixed fraction).

amid [387]
              This is a normal distribution with a Mean: 14 g/dL and a Standard deviation: 1 g/dL.
    A ) Hemoglobin levels less than 13:
    13 = 14 - 1 = Mean - 1 SD
    0.16  x 200 = 32
    Answer:  32 people.
    B ) Hemoglobin levels greater than 14 :
     0.50  x 200 = 100
     Answer:  100 people.

The owners of the pet sitting business have set aside $48 to purchase chewy toys for dogs, 2,
Contact [7]

6 chewy toys and 6 cat collars are needed to have the same amount or price at both stores.

<h3>Equation</h3>

An equation is an expression used to show the relationship between two or more angles and variables.

Let x represent the number of dogs and y represent the number of cats collars. Hence:

At Marco's market:

2x + 6y = 48 (1)

At Sonia's superstore:

4x + 4y = 48  (2)

Graphing both equations, the solution is at (6,6)

6 chewy toys and 6 cat collars are needed to have the same amount or price at both stores.
