<em><u>Question:</u></em>

Anthony is riding in a race.The equation d=40-1/5m, where d= distance in miles and m= minutes,can be used to estimate the number of miles anthony has left before reaching the finish line.how many miles does anthony have to finish the race if he has been riding for one hour and twenty minutes?

<em><u>Answer:</u></em>

Antony has to ride for 24 miles

<em><u>Solution:</u></em>

Given that,

<em><u>The equation used to estimate the number of miles is:</u></em>

d = 40-\frac{1}{5}m

Where, "m" is the minutes and "d" is the distance

Given that Antony is riding for 1 hour 20 minutes

We know that,

1 hour = 60 minutes

1 hour 20 minutes = 60 minutes + 20 minutes = 80 minutes

<em><u>Substitute m = 80 in given eqn </u></em>

d = 40 - \frac{1}{5} \times 80\\\\d = 40 - 16\\\\d = 24

Thus Antony has to ride for 24 miles

I need help!
Naddik [55]

Answer:  Estimate: 36  ? units ? miles per hour ? feet per second?

Exact: 35.32142857  but if you are supposed to use significant digits, 35.32 is probably good.

Step-by-step explanation: For the estimate, round off the fractions to whole numbers, so multiply 6 x 6 to get 36

For exact I converted the mixed numbers to improper fractions, 5 3/4 = 23/4  and 6 1/7 = 43/7. Then multiplied the numerators 23 x 43= 989.  And denominators, 4x7=28.  

Divide numerator by denominator  989/28= 35.321428571

Pls help me with this and an explanation
SCORPION-xisa [38]

Answer:

The relationship in this equation is linear, but not proportional. If it was proportional, then replacing x with nx should give ny as the answer. Example:

y = 3x

Replace x with 2x.

y' = 3(2x) = 2(3x) = 2y

y' = 2y

This is proportional. But if you replace x with 2x in

y = 3x + 5,

you will not get 2y for y'. This case is not proportiona

Answer:

Domain = {1,2,3,4,5,6} and Range = {42,49,56,63,70,77The given function is :

y = 7x + 35

Where

x is no of members

y is the monthly cost

Your group has enough money for up to six members to joim fitness club. It means domain (the set of input values) are:

Domain = {1,2,3,4,5,6}

Put x = 1 to 6 one by one,

y = 7(1) + 35 = 42

y = 7(2) + 35 = 49

y = 7(3) + 35 = 56

y = 7(4) + 35 = 63

y= 7(5) + 35 = 70

y = 7(6) + 35 = 77

Range = {42,49,56,63,70,77}
