Answer:
Ernie's time is 11.1 seconds
Explanation:
If Bert won the race with the time of 12.6 and the time difference is 1.5, this means Ernie's time was 1.5 seconds less than 12.6.
12.6
−
1.5
=
11.1
Answer:
P(yellow or red) =8/15
Step-by-step explanation:
There are 15 marbles, 3 green, 4 blue, and 5 red marbles.
3+4+5 = 12
That means there are 15-12 = 3 3 yellow marbles.
3 green,
4 blue
5 red
3 yellow
To find the probability of yellow or red, we add the number of yellow and red marbles together over the total number of marbles
P(yellow or red) = (yellow +red)/ total
= (3+5)/ 15
=8/15
Answer:
3125 x 5th root (x)
Step-by-step explanation:
(3125 ) * x^(6/5)
When we have a some thing to a power greater than 1, we can separate it
We can rewrite 6/5 as 5/5 + 1/5
3125 x^(5/5+1/5)
We know a^ b *a^c = a^(b+c)
3125* x^5/5 * x^ 1/5
x^5/5 is x^1 or just x
3125* x * x^ 1/5
3125 x 5th root (x)
1/4 = 2/8
7/8 - 1/4 = 7/8 - 2/8 = (7-2)/8 = 5/8
Answer: 5/8
