Answer:

40 $\frac{9}{24}$

Step-by-step explanation:

First I would convert everything into an improper fraction to make it easier to multiply.

$\frac{57}{8}$ × $\frac{17}{3}$ = $\frac{969}{24}$

$\frac{969}{24}$ in simplest form is 40 $\frac{9}{24}$

Answer:

40 3/8

Step-by-step explanation:

7 1/8 = 57/8

5 2/3 = 17/5

57/8 *17/3 cross reduce it to 19/8 * 17/1

19/8 * 17/1 = 323/8

reduce to 40 3/8

At the end of an advertising campaign, the weekly sales declined. The weekly sales y (in dollars) are modeled by the equation y

kkurt [141]

Answer:

c)$24,000

Step-by-step explanation:

The function that models the decline of the sales is

$y = 6000(4 - 0.09x)$

where x is the number of weeks after the end of the campaign.

At the end of the campaign, will be no more weeks left.

So we x=0, and solve for y,

$y = 6000(4 - 0.09 \times 0) \\ y = 6000(4 -0) \\ y = 6000(4) = 24000$

The correct answer is c)$24,000

A. yes...it is a function because there is no repeating x values.
B. (5,2)(6,5)...slope = (5 - 2) / (6 - 5) = 3
y = mx + b
slope(m) = 3
(5,2)...x = 5 and y = 2
now we sub
2 = 3(5) + b
2 = 15 + b
2 - 15 = b
-13 = b
so the equation is : y = 3x - 13
when x = 7
y = 3(7) - 13....y = 21 - 13....y = 8

f(x) = 2x + 13...when x = 7
f(7) = 2(7) + 13...f(7) = 14 + 13.....f(7) = 27

the function has a greater value

C. f(x) = 2x + 13....when f(x) = 75
75 = 2x + 13
75 - 13 = 2x
62 = 2x
62/2 = x
31 = x

Answer:

$420

Step-by-step explanation:

Principal = $7000

Rate = 8%

Time = 9 months

9 months = 3/4 or 0.75 of a year

Simple Interest = Principal * Rate * Time ÷ 100

= $7000 * 8% * 0.75 ÷ 100

= $420
