How long would it take to travel 425 m at the rate of 50 m/sm/s ?
2 answers:
Answer:
8.5 s
Step-by-step explanation:
How long means time taken, so to find the time taken to travel 425 m at the rate of 50 m/s, we will simply use the formula below
V =
where v is the speed or velocity, d is the distance travelled and t is the time taken.
From the question given, distance (d) = 425 m, velocity/speed(v) = 50
We can now proceed to insert our values into the equation
V =
50 =
Cross -multiply
50 t = 425
Divide both-side of the equation by 50
=
(On the left-hand side of the equation 50 at the numeartor will cancel-out 50 at the denominator leaving us with just x, while on the right-hand side of the equation 425 will be divided by 50)
t = 8.5 sec.
Therefore the time taken is 8.5 s

Answer:
Step-by-step explanation:
We have the exponential function of the form:
And it goes through the points (0, 13) and (3, 832).
Hence, when we substitute in 0 for x, we should get 13 for y. Therefore:
Since anything to the zeroth power is 1, this yields:
So, we determined that the value of a is 13.
So, our function is now:
We will need to determine b. We know that y equals 832 when x is 3. Hence:
Divide both sides by 13:
Take the cube root of both sides:
Hence, our b value is 4.
Therefore, our entire equation is:

Given, Shelby made 5 quarts of juice for a picnic.
We know that 1 quart of juice = 4 cups of juice.
Here we will have to convert 5 quarts to cups.
As for 1 quart there are 4 cups, to find 5 quarts we have to multiply 4 times 5.
So 5 quarts of juice = cups of juice.
We know that,
5 quarts of juice = 20 cups of juice.
We have got the required answer here.
Shelby made 20 cups of juice there in the picnic.
