When the turnpike littered the toll, traffic increased from 1,500 cars per day to 2,700

umka21 [38]

Answer:

80%

Step-by-step explanation:

The percentage change between two numbers can be calculated as ...

percentage change = ((new value)/(old value) -1) × 100%

= (2700/1500 -1) × 100% = (1.80 -1) × 100% = 80%

Traffic volume increased 80%.

Find the distance between the points (-4, -5 and (3, -1.

Komok [63]

≡ We know that:
⇔ $(x_{1},y_{1})$ → $(-4,-5)$
⇔ $(x_{2},y_{2})$ → $(3,-1)$

≡ Solution:
⇒ $\sqrt{[(x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2}]}$
⇒ $\sqrt{[(3-(-4))^{2}+(-1-(-5))^{2}]}$
⇒ $\sqrt{[7^{2}+4^{2}]}$
⇒ $\sqrt{[49+16]}$
⇒ $\boxed{\sqrt{65}}$
