Equivilent means equals to
0.25 means 25 hundreths
hundreths is 1/100
25 hundreths=25/100=5/20=1/4
so it could be
0.25 kg=1/4kg
Answer:
3.33 meters per second
Step-by-step explanation:
you must find the total time that Mr. B spent to complete the swim and bike.
Information:
0h 25' 10'' ---------> Swim
1h 30' 50'' ---------> Bike
he spent 1h 55' 60'', this is 1h 56'.
now you must substract this time from the record time to find the time alloted to run:
first you convert both times into minutes:
now substracting:
so he must travel 10 km in 50 minutes, that is:
speed = distance/time
1 km is equal to 1000 meters and 1 minute is equal to 60 seconds.
so Mr.B's speed must be 3.33 meters/sec
Answer:
Step-by-step explanation:
Put x as y-6 in the second equation.
Factor.
It has to be a positive integer.
Substitute y as 11.
Answer: the function that has the smaller minimum is g(x), and the cordinates are (0,3)
Step-by-step explanation:
We have a function for f(x) and a table for g(x)
first, quadratic functions are symmetrical.
This means that if the minimum/maximum is located at x = x0, we will have that:
f(x0 + A) = f(x0 - A)
For any real value of A.
Then when we look at the table, we can see that:
g(-1) = 7
g(0) = 3
g(1) = 7
then the minimum of g(x) must be at x = 0, and we can see that the minimum value of g(x) is 3.
Now let's analyze f(x).
When we have a quadratic equation of the shape.
y = a*x^2 + b*x + c
the minimum/maximum will be located at:
x = -b/2a
In our function we have:
a = 3
b = 6
then the minimum is at:
X = -6/2*3 = -1
f(-1) = 3*(-1)^2 + 6*-1 + 7 = 3 - 6 + 7 = 3 + 1 = 4
Then the function that has the smaller minimum is g(x), and the cordinates are (0,3)
Answer:
503.2 cm^2 to the nearest tenth.
Step-by-step explanation:
Circumference = 2 * radius * 3.14
79.50 = 2*3.14 r
r = 79.50 / 6.28 = 12.659 cm.
So the area = 3.14 r^2
= 3.14 * 12.659^2
= 503.186 cm^2.
