Ade cycled for 2 hours at an average speed of 15 km/h. Kali travelled the same route as Ade but it took her 2 hour 15 minutes. What is Kali's average speed to 1 dp?

Answers

Answer 1

Answer: 14.0 km/h

Step-by-step explanation:

First find the distance that both Ade and Kali travelled. Use the time and speed of Ade to find this out:

Distance = Speed * Time

= 15 * 2

= 30 km

Kali took 2 hours 15 minutes to travel 30km. Her speed is therefore:

= Distance / Time

Convert the time to decimal:

Mixed fraction = 2¹⁵/₆₀

= 2¹/₄

Decimal = 2.15 hours

Average speed = 30 / 2.15

= 13.95

= 14.0 km/h

Mary invests $1.200 in an account that earns 6% annual interest, compounded continuously. What is the value of the account after 7 years? Round your answer to the nearest dollar

Answers

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

Imagine the bike shop sells bike rentals for a local bike tour. The tour costs $50 for equipment plus $7.50 per hour. Explain how you could find the total cost of a 5-hour bike tour.

Answers

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

The great Chicago fire i have assignment on that what do this mean?​

Answers

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).

solve for x in the following...pls explain

a)7x+5=3x-1
b)5x+12=3x+14​

Answers

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]

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)
