Answer:

25 liters of petrol

Step-by-step explanation:

78 km = 6 liters

So the ratio is 78:6

Let's find the distance per liter:

78/6 = 13

So you travel 13 km per liter

To find the amount of liters for 325 km, you divide 325 by 13:

325/13 = 25

You would need 25 liters of petrol to travel 325 km.

Paul and Tom both commute to work. Paul's commute on the train takes 15 minutes more than one third as many minutes as Tom's com
Ronch [10]

Answer:

  45 = (one third)x + 15

Step-by-step explanation:

If x represents the number of minutes Tom commutes, then (1/3)x is "one-third as many minutes as Tom's commute." 15 minutes more than that is ...

  (1/3)x + 15

We are told this is the length of Paul's commute, and that it is 45 minutes. So, the appropriate equation is ...

  45 = (1/3)x +15

Shtirlitz [24]

The probability that the next chew Oliver removes from the bag will be peach chew as a percent to the nearest whole number will be 13%.

<h3>What is probability?</h3>

Its basic premise is that something will almost certainly happen. The percentage of favorable events to the total number of occurrences.

Oliver has a bag that contains pineapple chews, lemon chews, and peach chews.

He performs an experiment.

Oliver randomly removes a chew from the bag, records the result, and returns the chew to the bag.

Oliver performs the experiment 23 times.

The results are shown below:

A pineapple chew was selected 17 times.

A lemon chew was selected 4 times.

A peach chew was selected 2 times.

Then the probability that the next chew Oliver removes from the bag will be peach chew as a percent to the nearest whole number will be

Total event = 24 times

Favorable event = 3 times

Then we have

P = 3 / 24 x 100

P = 0.125 x 100

P = 12.5%

P ≅ 13%

PLEASE HELP WITH GRAPH LAST QUESTION I NEED ​
SVETLANKA909090 [29]

Answer:

\sf g(x) = -1(x+3)^2 -2

Explanation:

\sf original \ graph:  \ y=-x^{2}

the graph is translated 3 units to the left and 2 units down.

vertex: (-3,-2) point: (-1,-6)

\sf so \ new \ graph :

\sf y = a(x-h)^2 +k

\sf -6 = a(-1-(-3))^2 -2

\sf -6 = 4a -2

\sf 4a = -4

\sf a = -1

\sf equation:

\sf y = a(x-h)^2 +k

\sf y = -1(x+3)^2 -2
