Answer:
1/16
Step-by-step explanation:
We know that a^ -b is equal to 1 / a^b
That means
4^-2 = 1/ 4^2 = 1/16
Answer:
"You" are 0.83.
(Alternative fraction version: 83/100)
Step-by-step explanation:
First, let's turn 3/4 and 9/10 into decimals.
3/4 becomes 0.75, and 9/10 becomes 0.9.
We know that it has to be a decimal, and we also know it must be greater than 0.75 but less that 0.9.
It can't be 0.73, since that's less than 0.75. It also can't be 0.93, since that's over 0.9. That means we're left with 0.83.
Our final answer is 0.83, AKA 83/100.
the horizontal distance ( x direction) from A to C is 7 units and
the vertical distance ( y direction) is 5 units
Applying Pythagoras' Theorem to the right triangle
AC² = 7² + 5² = 49 + 25 = 74, hence
AC =
= 8.6 units ( to 1 dec. place )
Let d be distance travelled when they are level , and t = time that nora took to get level with mason
for Nora
6 = d/t
d = 6t
for Mason
5 = d / (t + 35)
d = 5 ( t + 350
so 6t = 5(t + 35)
solve for t
