Answer:
3.2ft long shadow
Step-by-step explanation:
In this problem we are given a ratio between the tree/shadow and woman/shadow therefore we are given 3 values and 1 unknown then we can use the Rule of Three to calculate the length of the shadow which we will refer to as x. The Rule of Three simply multiplies the diagonal values and divides by the third value in order to get the missing unknown like so...
55ft tall <======> 32ft long shadow
5.5ft tall <======> x ft long shadow
(5.5 * 32) / 55 = 3.2ft long shadow
Finally, we can see that the woman's shadow would be a 3.2ft long shadow
It would be (b) 3/5 because
Terminating decimal is a decimal with a definite amount of digits, meaning that it stops after a certain digit.
The other answers:
(A) 3/7 = 0.42857143.....
(C) 1/3 = 0.333333333333.....
And (D) = 0.27272727272.....
And only 3/5 (B) stops after a certain digit because it's decimal value is 0.6.
Hope this helps!
<span>This is decay. The exponent has a negative sign. The reciprocal of 2 is 0.5. So N(t) can be rewritten as 0.5^(t/8). The base is fraction less than 1, which is decay.</span>
Step-by-step explanation:
Rotations, reflections, and translations are isometric. That means that these transformations do not change the size of the figure. If the size and shape of the figure is not changed, then the figures are congruent.
I hope it's helpful!
