In triangle ABC, the size of angle B is 5 times the size of angle A, and the size of angle C is 7 less than 4 times the size of
kipiarov [429]
It sounds like everything is being described in reference to angle A, so a good starting point is to pick a variable to represent the measure of angle A. I'm going to use "a" for that.

Next, I'm going to take the verbal descriptions in the problem and "translate" them into "math language". They say angle B is 5 times angle A, so that means the measure of angle B is actually 5a. The size of angle C is 5 degrees less than 4 times the size of A, so that translates to 4a-5.

We now know the following:

Angle A: a
Angle B: 5a
Angle C: 4a-5

Now, to find the value of a, we need to remember that all the angles in a triangle add up to 180 degrees.

So we have: a+5a+4a-5 = 180

We can solve that equation by combining like terms to get: 10a-5=180

We can add 5 to both sides: 10a =185

And divide by 10: a = 18.5

That tells us the measure of angle A! (It's 18.5 degrees). Now we can go back and find B by multiplying A by 5. We get 92.5 degrees for that.

Finally, we can find C by taking 4*18.5-5. We get 69 degrees for that.

One last thing-- let's check that they really do add up to 180! 69+92.5+18.5 = 180. Yep!

Hope that helps you!!

Determine whether each equation represents a
luda_lava [24]

Answer:

Answer: B

Step-by-step explanation:

The y intercept must be 0. The y intercept for a = - 2. This is not

a proportional relationship

The same comment can be made for C. The y intercept is 1. So C is not the answer.

A box contains 15 resistors. Ten of them are labeled 50 Ω and the other five are labeled 100 Ω.
Mnenie [13.5K]

Answer:

a) 0.3333

b) 0.2381

c) 0.0952

d) 0.4286

e) 0.4523

f) 0.2637

Step-by-step explanation:

The concept applied here is dependent probability or probability without REPLACEMENT

  • Given 15 resistors = Total
  • 50 Ω  = 10 resistors
  • 100 Ω = 5 resistors

a) What is the probability that the first resistor is 100Ω?

P(first resistor 100Ω) = number of 100Ω / Total number of resistors

= 5/15 = 0.3333

b) P( second resistor 100 Ω, the first resistor 50 Ω?

= Since second resistor of 50Ω was drawn first, the total number of resistors would have reduced, but the 100Ω resistor still maintains its number

= 10/15 x 5/14 = 0.2381

c) P( second resistor is 100 Ω, the first resistor is 100 Ω)

In this case, since first resistor is drawn, the number of 100 Ω would have reduced so also the total number of resistors

= 5/15 x 4/14 = 0.0952

d) P( that the first two resistors are both 50Ω) = Implies picking 2- 50Ω

= 10/15 x 9/14 = 0.4286

e) P(total of two resistors are selected from the box) = P( first 100Ω and second- 50Ω) or P( First 50Ω and second 100Ω) = 10/15 x 5/14 + 5/15 x 9/14 = 0.4523

f) P( more than three resistors are selected from the box) = 1 - P( Less than or equals to three resistors) - it implies that the consideration is for the 100Ω

= P( 1resistor) - P( 2- Resistor) - P( 3- Resistor)

1 - 5/15 - (10/15 + 5/14) - (10/15 + 9/14 + 5/13)

= 0.2637
