After several shares of the company's stock were sold, a profit of $1.320 was earned. The profit was 15%
Rom4ik [11]

Answer:

$8.8

Step-by-step explanation:

Let the original price of shares be x

Profit earned = $1.320

percentage profit = 15%

∴ \frac{15x}{100} = 1.320\\15x = 132.0\\x = \frac{132}{15} \\x = 8.8

Original price of shares were = $8.8

The number of views on an interesting video after it's uploaded is represented by the following table:
defon

Answer:

The model for V(t) ,the number of views, t ,months after it's uploaded, best fits the data is ,V(t)=50(6.25)^t

Step-by-step explanation:

Time (months)         Views

0                                  50

2                                  313

4                                  1950

6                                  12,210

8                                  76,300

10                                 476,800

(x_1,y_1)=(0,50)\\(x_2,y_2)=(2,313)\\(x_3,y_3)=(4,1950)

Slope = \frac{y_2-y_1}{x_2-x_1}

Slope = \frac{313-50}{2-0}

Slope =131.5

Slope = \frac{y_3-y_2}{x_3-x_2}

Slope = \frac{1950-313}{4-2}

Slope =818.5

Since the slope is not same . So, it is not a linear relationship

\frac{y_2}{y_1}=\frac{313}{50}=6.25\\\frac{y_3}{y_2}=\frac{1950}{313}=6.25

Since the ratio between the consecutive outputs is same so, it is exponential relationship.

Formula : y=ab^t

Where a is the initial value = 50

b = rate of change = 6.25

The model for V(t) ,the number of views, t ,months after it's uploaded, best fits the data

So,V(t)=50(6.25)^t

Find the value of x
Fiesta28 [93]

Answer:

x=26

Step-by-step explanation:

The sum of all angles in a triangle is equal to 180

x + 55 + (4x-5) = 180

Combine like terms

5x +50 = 180

Subtract 50 from each side

5x +50-50 = 180-50

5x = 130

Divide each side by 5

5x/5 =130/5

x =26

An architect presents a 3 inch wide by 4 inch deep by 3 inch tall model of a new central campus dorm . If the final building fou
IRISSAK [1]

Answer:

Building depth = 168 ft

Step-by-step explanation:

we must find the relationship (scale) of the model with respect to the building .

wide-m (model) = 3 in

deep-m(model) = 4 in

wide-b (building) = 126 feet

deep-b(building) = x

the measures must be standardized

let's convert feet to inches

12 in      →   1 feet

3   in     →   ?,   then

3 in → 0.25 feet and 4 in → 1/3 feet

now deep-m = x

x=\frac{(1/3)ft*126ft}{0.25ft}=168 ft
