The graph shows the relationship between the distance a bicyclist travels and the time in hours.

Mathematics
1 answer:
Vika [28.1K]3 years ago
8 0

Answer:

Step-by-step explanation:

a). Point (x, y) from the graph represents,

    x → Time in hours

    y → Distance traveled by the bicyclist (in miles)

    Therefore, point (4, 60) represents the distance 60 miles traveled by

the bicyclist in 4 hours.

b). Since, distance traveled (d) is proportional to the time taken(t).

    d ∝ t

    d = kt

    k = \frac{d}{t}

    Here k = constant of proportionality.

    k = \frac{60}{4} = 15

c). Therefore, equation in the form of y = kx will be,

    y = 15x

Solve a,b,c,d and e.​
Westkost [7]

Answer:

Step-by-step explanation:

a)

 428721

Place of 2's 10s and 10,000s

Therefore its value is 20 and 20,000

Product of the place value = 20 x 20,000 = 4,00,000

b)

37,20,861

Place of 7 is 1,00,000

Therefore the place value is 7,00,000

c)

Greatest 7 digit number is 99,99,999

Adding 1 to it = 99,99,999 + 1 = 1,00,00,000

d)

85642 = 80000 + 5000 + 600 + 40 +2

e)

round off 85642  to nearest thousand = 86,000

Of 560 marbles in a bag, 65% are red and the rest are blue. After 28 red marbles are replaced with blue ones, how many blue marb
jonny [76]

Answer:  The answer is 400  blue marbles.


Step-by-step explanation: Given that there are 560 marbles in a bag, out of which 65% are red and rest are blue.

So, number of red marbles is

n_r=65\%\times 560=\dfrac{65}{100}\times 560=364,

and number of blue marbles is

n_b=560-364=196.

Now, if 28 red marbles are replaced by blue marbles, the the new number of red and blue marbles will be

n_r^\prime=364-28=336~~~\textup{and}~~~n_b^\prime=196+28=224.

Now, to get 65% of the marbles blue, we need to add some more blue marbles to the bag. Let 'x' number of blue marbles are added to the bag, then

65\%\times (560+x)=224+x\\\\\Rightarrow \dfrac{65}{100}\times (560+x)=224+x\\\\\Rightarrow 13(560+x)=20(224+x)\\\\\Rightarrow 7280+13x=4480+20x\\\\\Rightarrow 7x=2800\\\\\Rightarrow x=400.

Thus, 400 blue marbles need to be added to the bag.

Hey!


1 car is $3.83.

3 cars is $3.83 × 3


3.83 × 3 = 11.49


Shipping fee is $4.55. Add that to the price of the 3 cars


11.49 + 4.55 = 16.04

Describe a method you can use to find the area of the following shape. Provide specific details in your answer, including coordi
Advocard [28]

There are a number of ways this can be done. One that is fairly simple is as follows.

Triangle ABC has base AC = 9 and height B to AC of 3 (found by counting squares). Thus its area is ∆ABC = (1/2)·9·3 = 13.5 square units.

Triangle ACF has base AC = 9 and height F to AC of 3, so will have the same area as triangle ABC, 13.5 square units.

Trapezoid CDEF has base CD of 6, base EF of 4 and height EF to CD of 6 (found by counting squares). Thus its area is CDEF = (1/2)(6 + 4)(6) = 30.

The total area of the entire figure is then

... ∆ABC + ∆ACF + CDEF = 13.5 + 13.5 + 30 = 57 square units.
