A car travels at constant speed for 7 days and covers 1500 miles. What is the speed in centimeters/minute? You may use the (appr

zvonat [6]

Answer:

Speed = 23809.52 cm/min

Step-by-step explanation:

Given : A car travels at constant speed for 7 days and covers 1500 miles.

To find : What is the speed in centimeters/minute

Solution : Formula to find speed is

$\text{Speed}=\frac{\text{Distance}}{\text{Time}}$

Distance traveled = 1500 miles and time taken = 7 days

$\text{Speed}=\frac{\text{1500 miles}}{\text{7 days}}$

Now, we have to convert miles into centimeter and days into minutes.

1 day = 24 hours

1 hour= 60 minute

24 hr= 24×60 minute

1 day = 24×60 minute

7 days = 7×24×60 minute = 10,080 minute

Now, 1 mile = 8/5 km = 1.6 km

1 km= 100000 cm

1.6 km = 1.6 × 100000 cm

1 mile = 1.6 × 100000 cm

1500 miles = 1500×1.6 × 100000 cm = 240,000,000 cm

Put back the values into speed

$\text{Speed}=\frac{\text{1500 miles}}{\text{7 days}}$

$\text{Speed}=\frac{\text{240,000,000 cm}}{\text{10,080 minute}}$

$\text{Speed}=\text{23809.523 cm/minute}$

Therefore, speed = 23809.52 cm/min

Mrs Smith has 12 times as many markers as color pencils the total number of markers and colored pencils is 78 how many markers d

Ainat [17]

Let the colored pencil amount be p.
Then this is the equation:
12p+p=78
Simplifying, we can see that
13p=78
Divide both sides by 13 to get
p=6

Since there are 12 times as many markers as colored pencils, there are 72 markers.

Nathaniel purchases a one year membership pass to an art museum as a member he receives a discounted entrance fee the total cost

Arturiano [62]

For this case, we must find the equation of the line.
The generic equation of the line is:
$y-yo = m (x-xo)
$
The slope of the line is:
$m = \frac{y2-y1}{x2-x1}$
Substituting values we have:
$m = \frac{15-12}{2-0}$
Rewriting:
$m = \frac{3}{2}$
$m = 1.5$
We now choose an ordered pair:
(xo, yo) = (0, 12)
Substituting values we have:
$y-12 = 1.5 (x-0)$
Rewriting the equation:
$y= 1.5x+12$
For 20 visits, we evaluate the equation when x = 20.
We have then:
$y= 1.5(20)+12$
$y= 30+12$
$y= 42$
Answer:
The discounted entrance fee is 1.5$. The total cost is 42$ after 20 visits
