Answer:

$1,826

Step-by-step explanation:

Given that

The amount invested is $1,200

The annual rate of interest is 6%

And, the time period is 7

We need to find the value of the account after 7 years in the case of compounded continuously

We know that for compounded continuously, the following formula should be used

= Amount invested ×e^(rate, time)

= $1,200 × e^(0.06 ×7)

= $1,200 × e^0.42

= $1,826

Answer:

301.440 mi²

Step-by-step explanation:

Surface area of a cylinder = 2πrh + 2πr²

Where,

Radius, r = 6 mi

Height, h = 2 mi

Surface area of a cylinder = 2πrh + 2πr²

= (2 * 3.14 * 6 * 2) + (2 * 3.14 * 6²)

= 75.36 + (6.28 * 36)

= 75.36 + 226.08

= 301.44 mi²

To the nearest thousandth

Surface area of a cylinder = 301.440 mi²

Answer:

The Great Chicago Fire was a conflagration that burned in the American city of Chicago during October 8–10, 1871. The fire killed approximately 300 people, destroyed roughly 3.3 square miles (9 km 2) of the city, and left more than 100,000 residents homeless. The fire began in a neighborhood southwest of the city center.

Step-by-step explanation:

Origin

The fire is claimed to have started at about 8:30 p.m. on October 8, in or around a small barn belonging to the O'Leary family that bordered the alley behind 137 DeKoven Street.

Spread

When firefighters finally arrived at DeKoven Street, the fire had grown and spread to neighboring buildings and was progressing toward the central business district.

Aftermath

Once the fire had ended, the smoldering remains were still too hot for a survey of the damage to be completed for many days. Eventually, the city determined that the fire destroyed an area about 4 miles (6 km) long and averaging ⁄4 miles (1 km) wide, encompassing an area of more than 2,000 acres (809 ha).

Answer:87.5

Step-by-step explanation: I can find the total cost of a 5 hire bike tour because I'm given the unit rate and the amount of time to multiply it by.

The total cost of the five hours bike tour is $87.50

Cost of equipment = $50

Cost per hour = $7.50 per hour

The total cost of the equipment for five hours will be the addition of the fixed cost and the variable cost. This will be:

= $50 + $7.50h

where, h = number of hours = 5 hours

Total cost = $50 + $7.50(h)

= $50 + $7.50(5)

= $50 + $37.50

= $87.50

The total cost of the five hours bike tour is $87.50

A. x^2-9x+18

B. x^2-8x+16

C. 2x^2-5x-12

D. 12x^2-31x+7

Answer:

a) x = -1.5

b) x = 1

Step-by-step explanation:

For problem a, you can start by subtracting 3x from both sides to gather all the like terms together:

7x + 5 = 3x - 1

-3x         -3x

4x + 5 = -1

Next, to get the coefficients on one side, you subtract 5 from both sides:

4x + 5 =  -1

    -5      -5

4x = -6

Now, you divide by 4 on both sides to isolate x:

x = -6/4 = -1.5 --- > x = -1.5

For problem b, you start by subtracting 3x from both sides(kinda like problem a):

5x + 12 = 3x + 14

-3x          -3x

2x + 12 = 14

Next, you can subtract 12 from both sides, isolating the "x term".

2x + 12 = 14

       -12  -12

2x = 2

Lastly, you can divide by 2 to get x:

x = 1

1:

[tex]7x +5=3x-1\\7x+5-3x=-1\\7x-3x=-1-5\\4x= -1-5\\4x= -6\\x=-\frac{6}{4} (en donde ambos se divide entre 4)\\Respuesta / x=-\frac{3}{2}[/tex]

2:

[tex]5x+12=3x + 14\\5x+12-3x=16\\5x-3x=16-12\\2x= 16-12\\2x= 4\\x=4/2\\( se divide entre 2)x= 2[/tex]

Answer:

Picture please

Step-by-step explanation:

I cannot identify the 3-D shapes unless if there is a picture.

The total volume of the solid is 2,160 unit³.

Volume is a mathematical term used to describe how much three-dimensional space an item or closed surface occupies.

The unit of volume is in cubic units such as m3, cm3, in3 etc.

First, Base area

= 1/2 x b x h

= 1/2 x 15 x 12

= 15 x 6

= 90 unit²

Now, Volume of Figure

= Base area x h

= 90 x 24

= 2,160 unit³
