Tina is saving to buy a notebook computer. She has two options. The first option is to put $200 away initially and save $10 ever
omeli [17]

The <em>correct answers</em> are:


It would take 5 months and she would save $250.


Explanation:


Let m be the number of months.


For the first way of saving, $200 up front and $10 each month, the expression would be

200+10m.


For the second way of saving, $100 up front and $30 each month, the expression would be

100+30m.


Setting them equal gives us the equation

200+10m = 100+30m


Subtract 10m from each side:

200+10m-10m = 100+30m-10m

200 = 100+20m


Subtract 100 from each side:

200-100 = 100+20m-100

100 = 20m


Divide both sides by 20:

100/20 = 20m/20

5 = m


It would take 5 months.


$200 up front and $10 each month for 5 months:

200+10m

200+10(5)

200+50

250


She would save $250.

A movie theater has been charging $10.00 per person and selling about 500 tickets on a typical weeknight. After surveying their
kifflom [539]

Answer:

p(x) = -0.01x + 15

Step-by-step explanation:

Given

Let x represent the number of tickets, and p the charges

(x_1,p_1) = (500,10)

A reduction of 50c gives an increment of 50 tickets.

This gives:

(x_2,p_2) = (500+50,10-0,5) ---- 50c = \$0.5

(x_2,p_2) = (550,9.5)

Required

Determine the demand function

First, calculate the slope:

m = \frac{p_2 - p_1}{x_2 - x_1}

m = \frac{9.5 - 10}{550-500}

m = \frac{-0.5}{50}

m = -0.01

So, the equation is:

p = m(x - x_1) + y_1

p = -0.01(x - 500) +10

p = -0.01x + 5 +10

p = -0.01x + 15

Hence, the function is:

p(x) = -0.01x + 15

Please help, Will give brainliest
Talja [164]

Answer:

First since 2 of the options ask for the width of BM lets solve for it using the Pythagorean theorem for both sides of point L:

a² + b² = c²

30² + b² = 50²

b² = 50² - 30²

b² = 1600

b = 40    Line BL = 40 ft

Since the ladder is 50 feet it is the same length on the other side as well

a² + b² = c²

40² + b² = 50²

b² = 50² - 40²

b² = 900

b = 30        line LM is 30 ft

SO line lm + line bl = 30 + 40 = 70 ft

A is true because ^

B isn't true because as we solved for earlier, BL is 40

C is true because line LM is in fact 30 ft as we solved for

D is not true because as we said earlier BM is 70

E is true because the same ladder was used on both sides of the street
