A bicyclist traveled with a speed of 12 km/h from a camping ground to a station, located 60 km away. Write a formula expressing the dependence of the variable s on t, where s is the distance between the bicyclist and the station in km, t - the duration (time) of his travel in hours. Using the formula, find: s for t=3.5

Answers

Answer 1
Part a:
for t = 3.5 hours
velocity = distance / time
distance = velocity x time
distance = 12 x 3.5 = 42 km

Part b:
for s = 30 km
velocity = distance / time
time = distance / velocity
time = 30 / 12 = 2.5 hours

Step-by-step explanation:

A square has four sides and the area is 10,000 m^2. Area is determined by multiplying two sides. In this case, you can divide by two to get 5000, then again by 2 to get 2500.  Each side/dimensions are 2500m^2

A survey found that 12 out of every 15 people prefer eating out over cooking. If 500 people took the survey, how many people prefer eating out?

Answers

Answer:

400 people

Step-by-step explanation:

15 = 12

500 = x

Cross multiply

15x = 12 × 500

Divide both sides by 15

[tex]\frac{15x}{15}[/tex] = [tex]\frac{12 * 500}{15}[/tex]  (* means multiplication if you do not know)

[tex]\frac{12 * 500}{15}[/tex] = 100 × 4= 400 people

Divide 500 by 15 that equals 33.33 then multiply that number by 12 and that equals 399.96 which is then rounded up to 400/500 people prefer eating out rather than cooking at home.

Which point is a representation of cruising height in feet?
Point A
Point B
Point C
Point D

Answers

200ft.

Point C represent the cruising height.

What is number line?

when we represent the numbers on a line the numbers can be positive negative or any type are done on  number line zero is the center of the number line.

Given that air balloon height is 1000 feet from ground

and descended to 800 feet

present height of air balloon is 1000 - 800 = 200 feet

Hence according to no. line in figure 200 feet lie in point C

Tonya plans to join a fitness club. She researched the costs to join different clubs in her area and found that there is a linear relationship between the total cost of belonging to a club and the number of months that you are a member. Each club charges monthly dues, and some clubs require new members to also pay a one-time membership fee. The total costs of being a member for 6 months, 12 months, and 24 months at each of three clubs are shown in the table.

Total Cost of Fitness Club Membership
Length of membership
Club 1
Club 2
Club 3
6 months
$108
$120
$126
12 months
$216
$210
$252
24 months
$432
$390
$504

How many of the clubs require new members to pay a one-time membership fee?
A: 0
B: 1
C: 2
D: 3

Answers

b because it’s the only one that doesn’t double in value

The number of clubs that require new members to pay a one-time fee is one.

In order to determine which fitness club requires a one-time membership fee, the average cost per month for each club has to be determined.

Cost of membership per month = cost / number of months

Average cost of Club 1

Average cost for 6 months = $108/6 = $18

Average cost for 12 months = $216 / 12 = $18

Average cost for 24 months = $432 / 24 = $18

The average costs each month is the same. This means that there is no one-time membership fee in this club.

Average cost of Club 2

Average cost for 6 months = 120 / 6 = $20

Average cost for 12 months = $210 / 12 = $17.50

Average cost for 24 months = $390 / 24 = $16.25

The average costs each month is not the same. This means that there is a one-time membership fee in this club.

Average cost of Club 3

Average cost for 6 months = $126 / 6 = $21

Average cost for 12 months = $252 / 12 = $21

Average cost for 24 months = $504 / 24 = $21

The average costs each month is the same. This means that there is no one-time membership fee in this club.

The width of the fountain in Luke's drawing from the example is 2 cm. What is the width of the fountain in Isabella's scale drawing?

Answers

Answer:

2.5cm

Step-by-step explanation:

If Luke's scale for his drawing is 5m to 2cm, then it means that every 2cm on Luke's scale drawing represents 5m in real life. So since the width of the fountain is 2cm, the actual fountain width must be 5m. As established in the example, Isabella's scale factor from drawing to real life is 6/3=2, which means any measurement in cm on her drawing can simply be multiplied by 2 to obtain the real life measurement in m. So, to convert back the other way, from real-life to drawing, we just need to divide the value by 2 instead of multiply. So, if the real life value is 5m, then the width on her scale drawing should be 5/2 = 2.5cm.

Hope this helped!

Using proportions, it is found that:

The width of the fountain in Isabella's scale drawing is of 1.6 cm.

-----------------------------------

This question is solved by proportions, using a rule of three.

Isabella's scale is of 6m to 3cm, that is, 2m to 1cm.Luke' scale is of 5 m to 2 cm, that is, 2.5m to 1 cm.From this, it can be taken that a drawing of 250cm in Luke's scale is of 200 cm in Isabella's scale.What is the width of Isabella's drawing, considering that Luke's width is 2 cm?

200 cm - 250 cm

x cm - 2 cm

Applying cross multiplication:

[tex]250x = 400[/tex]

[tex]x = \frac{400}{250}[/tex]

[tex]x = 1.6[/tex]

The width of the fountain in Isabella's scale drawing is of 1.6 cm.
