Answer:
Step-by-step explanation:
<u><em>The correct question is</em></u>
If Triangle ABC is congruent with triangle DEF, DE=17, EF =13, DF =9, and BC = 2x-5, then which of the following is the correct value of x?
we know that
If two triangles are congruent, then their corresponding sides and their corresponding angles, are congruent
In this problem
The corresponding sides are
AB and DE
AC and DF
BC and EF
The corresponding angles are
∠A and ∠D
∠B and ∠E
∠C and ∠F
so
AB≅DE
AC≅DF
BC≅EF
and
∠A≅∠D
∠B≅∠E
∠C≅∠F
<em>Find the value of x</em>
BC≅EF
substitute the given values
Solve for x
Answer:
0.01000188
Step-by-step explanation:
The third term is ...
8C2·x^6·y^2 = 28 x^6 y^2
Putting in the given values for x and y, we get ...
28·3^6·7^2·10^-8 = 1000188×10^-8 = 0.01000188
_____
8C2 = 8!/(2!·(8-2)!) = 8·7/(2·1) = 28
Answer:
1.42 hours
Step-by-step explanation:
In this case we must take into account that the speed would be to fill a pool for a time, that this case is in hours, therefore it would be like this:
1/5 for the first pipe
1/2 for the second pipe
Now, we will use both at the same time, therefore:
1/5 + 1/2 = 1 / x
0.7 = 1 / x
x = 1 / 0.7
x = 1.42
That is to say that if we use both we will take a total of 1.42 hours

Answer:
It will be worth $128.
Step-by-step explanation:
After 1 year, 3/5 of 800 is 480 which leaves the value at $320, and then after 2 years, 3/5 of 320 is 192. 320-192 leaves the value at $128.
