Answer:
About 40 Minutes, Or something close to that
Step-by-step explanation:
The car covers 60 km in 90 minutes or its speed = 60 km*60/90 min = 40 km/hr . So to cover 100 km at the same speed it will take 100/40 = 40 Min
Answer:
Answer is A.
Step-by-step explanation:
AC=CB
<ACD=<BCD
DC=DC
We are given that the second figure is a dilation of the first one by 15. Thus, the ratio of their corresponding sides is equal to
C'D'E:CDE = 15:1
For the areas,
A of C'D'E': A of CDE = 225:1
Thus, if we have the area of CDE, we just have to multiply that with 225 to have the area of C'D'E'.
Evaluating a function at each element of a subset X of the domain, produces a set called the image of X under or through the function. The inverse image or preimage of a particular subset S of the codomain of a function is the set of all elements of the domain that map to the members of S.
