Debbie's city took a survey about a plan for a new park. The city surveyed 600 people. 60% of the people surveyed liked the plan
lukranit [14]
Hi there. 

All we have to do to find out how many people like the plan is multiplication.

We multiply the total number of people by 60% - in decimal form.

600 · 0.6 = 360

360 people liked the plan.

39 is the percent of 12.5
Rashid [163]
You mean '39 is what percent of 12.5 ?'

So, the answer is

39/12.5 × 100
= 3.12 × 100
= 312%

So, 39 is 312% of 12.5.

(The percentage is greater because 39 is greater than 12.5)

I cant figure this out
Rudik [331]

Answer:

x = 2 or x = -1/4

Step-by-step explanation:

Let's solve your equation step-by-step.

4x2−7x−2=0

For this equation: a=4, b=-7, c=-2

4x^2+−7x+−2=0

Step 1: Use quadratic formula with a=4, b=-7, c=-2.

x=\frac{-b\pm\sqrt{b^2-4ac} }{2a}

x=\frac{-(-7)\pm\sqrt{(-7)^2-4(4)(-2)} }{2(4)}

x=\frac{7\pm\sqrt{81} }{8}

x = 2 or x = -1/4

<u>Answer:</u>

x = 2 or x = -1/4
