Answer:

d = $\sqrt{74}$ or 8.60

Step-by-step explanation:

(5, 8) (-2, 3)

Let 5 = $x_{1}$

8 = $y_{1}$

-2 = $x_{2}$

3 = $y_{2}$

Plug in the values into the equation to get the distance:

d = $\sqrt{(x_{2}-x_{1})^{2} + (y_{2}-y_{1})^{2} }$

d = $\sqrt{(-2-5)^{2} + (3-8)^{2} }$

d = $\sqrt{(-7)^{2} + (5)^{2} }$

d = $\sqrt{49 + 25}$

d =  $\sqrt{74}$ or 8.60

Tim and Al are bricklayers. Tim can construct an outdoor grill in 5 days. If Al helps Tim, they can build it in only 3 days. How

KATRIN_1 [288]

Answer:

It would take Al 7.5 days to build the grill alone.

Step-by-step explanation:

Since Tim and Al are bricklayers, and Tim can construct an outdoor grill in 5 days, and if Al helps Tim, they can build it in only 3 days, to determine how long would it take Al to build the grill alone should be done the following calculation:

1/5 + X = 1/3

0.20 + X = 0.333

X = 0.333 - 0.20

X = 0.1333333

X = 1 / 7.5

Therefore it would take Al 7.5 days to build the grill alone.
