UNO [17]3 years ago
3 0
Given:
yesterday = 270
today = 216

yesterday's number of tickets sold is the basis of the percent of change. So, 270 is the 100%.

270 - 216 = 54  * value of the change in ticket sales

54/270 = 0.20 x 100% = 20%  * percent of change

There was a 20% decrease in ticket sales.

Anika [276]

Answer:

Answer is: $148,809.52

Step-by-step explanation:

Susan has purchased a whole life policy with a death benefit of $200,000.

Assuming that she dies in 10 years.

Rate = 3% or 0.03

Future value after 10 years = (1+r)^{n} = (1.03)^{10} = 1.344

Purchasing power of proceeds = \frac{200000}{1.344}= $148,809.52

Company ABC produces widgets. They have found that the cost, c (x), of making x widgets is a quadratic function in terms of x. T
Dahasolnce [82]

The given function  is a quadratic equation. Any quadratic equation can be written in the form :

C(x)=ax^{2}+bx+c

The given points can be taken as (2,23) ,(4,55) and(10,247)

We form three equations with the given points

For point (2,23 ) the equation is

23   = 4a + 2b + c

For point (4,55) the equation is

55 = 16a + 4b + c

For point  (10,247) the equation is:

247 = 100a+10b+c.

Solving the three equations for a,b,c we have :

32 = 12a + 2b

  16 = 6a + b

and,

 192 = 84 a + 6b

 32 = 14a + b

Solving for a,b,c we have:

a=2  b=4   c=7

The quadratic equation is c(x)=2x^{2}+4x+7.

When x=8

c(x)=2(8)^{2}+4(8)+7= 167.]

Option C. $167 is the right answer.

amid [387]

Answer:

123°

Step-by-step explanation:

2z +9 = x

y = z

2Z +9 + X + z +Y = 360

Substitute for Z

2Z +9 + 2z +9 + z + z = 360

6z +18 = 360

6Z = 342

Z = 57

2(57) +9 = 123

X = 123
