Use the graph to determine which one of the three statements is a lie.

1) The average rate of change between (0,4) is positive

2) The average rate of change between (-3,4) is negative

3) The average rate of change between (0,4) is 3/4

Ram started his journey at 6:00 AM with an average speed at 20km/hr.

Hari started his journey two hours later (at 8:00 AM) with an average speed of 30km/hr.

We have to find time at which they meet each other[tex].[/tex]

★ Let they meet each other after t hours wrt 6:00 AM.

At that time, distance covered by ram must be equal to the distance covered by hari.

We know that,

➤ Distance covered by Ram :

⭆ d₁ = v₁ × t

⭆ d₁ = 20 × t

➤ Distance covered by Hari :

Since hari started his journey after 2 hours so will take time = (t - 2) hours

⭆ d₂ = v₂ × (t - 2)

⭆ d₂ = 30 × (t - 2)

⭆ d₂ = 30t - 60

Now,

➠ d₁ = d₂

➠ 20t = 30t - 60

➠ 30t - 20t = 60

➠ 10t = 60

➠ t = 6 hrs

∴ They will meet at (6 + t) = 12PM

Answer:  12:00 pm  (Noon)

Step-by-step explanation:

Let t represent the time (in hours) from 6:00 am

Use distance (d) = rate (r) × time (t)

Ram: time = t,      r = 20     →      d = 20t

Hari: time = t - 2, r = 30    →       d = 30(t - 2)

Use Substitution method to solve the system of equations:

20t = 30(t - 2)

20t = 30t - 60

-10t = -60

    t = 6

They travel the same distance when Ram rides his bike for 6 hours

and Hari rides his bike for 4 hours.

Ram: 6:00 am + 6 hours = 12:00 pm (Noon)

Hari: 8:00 am + 4 hours = 12:00 pm (Noon)    [tex]\checkmark[/tex]

Answer:

90 = 150 of 60

88 = 220 of 40

75 = 300 of 25

100 = 125 of 80

Step-by-step explanation:

Answer:

90 = 150% of 60$

88 = 220% of 40$

75 = 300% of 25$

100 = 125% of 80$

Answer:

[tex]g^{-1}[/tex] (x) = [tex]\frac{x+11}{4}[/tex]

Step-by-step explanation:

let y = g(x) and rearrange making x the subject, that is

y = 4x - 11 ( add 11 to both sides )

y + 11 = 4x ( divide both sides by 4 )

[tex]\frac{y+11}{4}[/tex] = x

Change y back into terms of x , with x = [tex]g^{-1}[/tex] (x) , thus

[tex]g^{-1}[/tex](x) = [tex]\frac{x+11}{4}[/tex]

Answer:

$2 dollars and 50c

Step-by-step explanation:

124 + 4 equals 128 and 320 divided by 128 is 2.5, so 2 dollars and 50 cents.

Answer:

300$

Step-by-step explanation:

If he save 10 for every 50, you  just divide. 60/10 = 6. He saved 6 times, if each time he saves he has 50 extra dollars, 6 * 50 = 300 because 6*5 = 30 and there is a extra 0 so 30 and 0 is 300

Answer:

It would be a 3/4 chance that he will pull the right 4 coins.

Step-by-step explanation:

The probability that the first 3 coins are equal to $0.40 will be 1/4

Simon needs to pull out the penny last so that the first three coins add up to $0.40. We assume the coins are wrapped so it is a random choice.

For the first coin, the probability of not pulling a penny is 3/4, similarly, for the second coin, the probability of not pulling a penny is 2/3,

For the third coin, the probability of not pulling a penny is 1/2,

P(3 coins but no penny) = (3/4*2/3*1/2) = 1/4

Answer:

negative

Step-by-step explanation:

Suppose we have positive integer x and negative integer -y.

Subtracting x from -y gives:

-y - x

Clearly, if -y is negative and we're subtracting even more (x) from it, the answer will still be negative.

So, the sign is negative.

Answer:

X is equal to -10

Step-by-step explanation:

#1. Multiply 6 to (1+x). Doing this makes this equation: 6+6x+x=-14

#2. Then add 6x and x to get: 7x+6=-14

#3. Then move 6 to other side of equation, while at the same time, changing it's absolute value: 7x=-14-6

#4. now you have: 7x=-20, now just divide 7 by -20 WooHoo! You finished it! you have: -2.85714285714 or 2 and 43/50.

Answer:

x=33

Step-by-step explanation:

The angles would need to add to 180 to be supplementary

4x+ x+15 = 180

Combine like terms

5x+15 = 180

Subtract 15 from each side

5x+15-15 =180-15

5x = 165

Divide by 5

5x/5 =165/5

x=33
