I think snail D could travel 12 in an hour because you need to double it!

Good Afternoon, 

I will go over each one so you understand:
  
       First Question: How far can snail D travel in 1 hour?
Well, we know That snail D travels 6 inches in 30 minutes, and we also know that 30 minutes is \frac{1}{2} of an hour. Therefore, we can multiply 30 minutes by 2 to get an hour, and do the same with the amount of inches this snail travels. So 6 x 2 = 12. He travels 12 inches in an hour :)
   
      Second Question:  Here we do the same thing, except the snail travels 1 inch in 15 minutes and we want to know how much he travels in 30 minutes, so 2 x 1 = 2. The snail travels 2 inches in 30 minutes. Thats a slow snail!

The formula can be used to work outthe cost, in riyals, of hiring a helmet inQatar for a number of days.Kasun wants to hire a bi
Margaret [11]

Answer:

The answer is below

Step-by-step explanation:

a) Cost of hiring the bicycle for 14 days is:

Cost = 65 * 14 days + 44 = 954 riyals

b) The number of days the bicycle is hired is to be the same as the number of days the bicycle is to be hired. Let us assume that the bicycle and helmet is to be hired for x days, hence:

Cost of bicycle = 65 * x + 14 = 65x + 44

Cost of helmet = 12.5 * x = 12.5x

Total cost = 65x + 44 + 12.5x = 77.5x + 44

Since 750 riyals is available, hence:

750 = 77.5x + 44

77.5x = 706

x = 9.11

Therefore the maximum number of days is 11. The total cost for 11 days is:

Total cost = 77.5(9) + 44 = 741.5 riyals

Money not spent = 750 riyals - 741.5 riyals = 8.5 riyals

Write the exponential function.
sertanlavr [38]

Answer:

f(x) = 10*(b)^x

Step-by-step explanation:

exponential function : y=a*(b)^x

where a = y intercept and b = factor ( what you multiply by )

looking at the table the y intercept is at (0,10) so a = 10

so we now have y = 10 * (b)^x

to find the factor we simply plug in one of the ordered pairs.

note that the ordered pair chosen does not effect the outcome

i chose (2,250)

we have y = 10 * (b)^x

(x,y) = (2,250)

250 = 10 * (b)^2

divide both sides by 10

25 = b^2

take the square root of both sides

5 = b

the final equation would be f(x) = 10 * (b)^x

Help me or give me answer key plz asap
Brut [27]

<u><em>Hello, this should help you out!</em></u>

In this graph, the y values move up 3 units each. Therefore, the blue parabola underwent a translation of 3 units upward.

For further explanation, we see that (0,0) goes up to (0,3), meaning the graph shifted upwards 3 units. So, each y value is raised by positive 3 units!

A grocery store sells twelve bottles of water for $13.80 a convenient store sells ten bottle of water for $11.80. which store ha
Mrac [35]

At the same rate, the price of 12 bottles of water at the convenience store would be

(12/10)·$11.80 = $14.16 . . . . . this is more than $13.80

On average the cost for the same number of bottles of water is higher at the convenience store. The grocery store has the better buy.
