Answer:
(c) CPCTC
Step-by-step explanation:
The proof might go something like this:
- EH ≅ KH, FH ≅ JH . . . . . given
- ∠EHF ≅ ∠KHJ . . . . . vertical angles are congruent
- ∆EHF ≅ ∆KHJ . . . . . SAS congruence theorem
- EF ≅ KJ . . . . . CPCTC
Note that JK is an alternate name for segment KJ. We used KJ in the proof because vertices K and J correspond directly to vertices E and F in the congruent triangles.
It depends on how much they are selling there cookies for and also who has more cookies.
Answer: d-9
Step-by-step explanation: d equals the savings so it says she spent four dollars and then five, so just add those and subtract it from the savings
Answer:
1. After rearranging the formula as 's' i.e speed is the subject will be given as
.
2. The average speed of a truck that travels a journey of 748 km in 11.5 hours is 65.04 kilometre per hour.
Step-by-step explanation:
Ans 1. subject means it come first in the sentence, hence here question is like write speed first in the formula so we have
Ans 2.
Given :
Total distance of a journey = 748 km
Total time taken for the journey = 11.5 h
To Find:
Average speed =?
Solution :
average speed is defined as of total distance covered divided by total time taken.
So, we have
The perimeter is 41.7.
We first find the distance between each vertex using the distance formula:
We now find the perimeter by adding all of the side lengths:
14+7.81+19.92 = 41.73 ≈ 41.7
