Answer:

45 = (45+18)

55 = (55+y)

55+y= (63 ×55) /45

y= 77- 55

y = 22 cm

45 = 63

x = 70

x= (45×70)/63

x = 50 cm

The value in dollars v(x), of a certain truck after x years is represented by the equation v(x)= 32,500(0.92) raised to the x po

s2008m [1.1K]

The 32,500 is the original cost of the truck and the (0.92) You take v(x)=32,500(0.92)
and raise that to the 2nd power, to represent the 2nd year and you will get an answer of $27,300.
Each year the truck is losing $2,600 in value, after two years the truck has lost $5,200 in value equalling
= $27,300

Transversal cuts parallel lines and at points X and Y respectively. The point nearest to C is X, and the point nearest to D is Y

hammer [34]

Answer: The answer is (B) ∠SYD.

Step-by-step explanation: As mentioned in the question, two parallel lines PQ and RS are drawn in the attached figure. The transversal CD cut the lines PQ and RS at the points X and Y respectively.

We are given four angles, out of which one should be chosen which is congruent to ∠CXP.

The angles lying on opposite sides of the transversal and outside the two parallel lines are called alternate exterior angles.

For example, in the figure attached, ∠CXP, ∠SYD and ∠CXQ, ∠RYD are pairs of alternate exterior angles.

Now, the theorem of alternate exterior angles states that if the two lines are parallel having a transversal, then alternate exterior angles are congruent to each other.

Thus, we have

∠CXP ≅ ∠SYD.

So, option (B) is correct.

A population of voters contains 40% republicans and 60% democrats. it is reported that30% of the republicans and 70% of the demo

Blizzard [7]

To get the probability of selecting a person who is a democrat and is favour to the issue, let us first calculate for the portions in each party who is favour on the issue.

p (rep & favour) = 0.4 * 0.3 = 0.12

p (dem & favour) = 0.6 * 0.7 = 0.42

Therefore the total portions who are favour is:

p (favour) = 0.12 + 0.42 = 0.54

Hence the probability is:

P (dem & favour) = 0.42 / 0.54 = 0.7778 = 0.78

Therefore there is about 78% probability that the person selected who is favour to the issue is a democrat.
