Answer:

C is the correct answer.

Step-by-step explanation:

All of the angles in a triangle add up to 180 degrees. 65+80=145 and when you do 180-145, you get 35 degrees. You can check to see if it's correct by adding 35, 65, and 80 together.

65+80=145

180-145=35

35+65+80=180

-Dominant- [34]

Answer:

1/2

Step-by-step explanation:

We do change in y over change in x

<u>Formula for Rate of Change on Slope</u>

y2-y1/x2-x1

<u>For Y</u>

We use coordinate (-2, -4)

-4--2

= -2 - -4

= 2

<u>For X</u>

We use coordinate (0, -4)

0 -- 4

= 0 + 4

= 4

Now we put y over x to find the rate of change in slope

2/4, simplified would be 1/2

Gena attached a dog ramp to her sofa, which allows her oldest dog to easily climb onto a seat cushion. The ramp is 55 inches lon
matrenka [14]

The distance from the base of the ramp to the base of the sofa rounded to the nearest tenth is 47.3 inches.

<u><em>Explanation</em></u>

According to the diagram, length of the ramp is, AC= 55 inches. The top of the seat cushion is 28 inches above the floor. That means, BC=28 inches

We need to find the distance from the base of the ramp to the base of the sofa which is AB

In right angle triangle ABC, using Pythagorean theorem...

AC^2 = AB^2 + BC^2\\ \\ (55)^2= AB^2 + (28)^2 \\ \\ AB^2 = (55)^2 - (28)^2 \\ \\ AB^2 = 3025 - 784\\ \\ AB^2 = 2241\\ \\ AB = \sqrt{2241}= 47.3

So, the distance from the base of the ramp to the base of the sofa rounded to the nearest tenth is 47.3 inches.

A machine has four components, A, B, C, and D, set up in such a manner that all four parts must work for the machine to work pro
olchik [2.2K]

Answer:

0.756

Step-by-step explanation:

It is given that a machine has four components, A, B, C, and D.

P(A)=P(B)=0.93, P(C)=0.95,P(D)=0.92

If these components set up in such a manner that all four parts must work for the machine to work properly.

We need to find the probability that the machine works properly. It means we have to find the value of P(A\cap B\cap C\cap D).

If two events X and Y are independent, then

P(X\cap Y)=P(X)\times P(Y)

Assume the probability of one part working does not depend on the functionality of any of the other parts.

P(A\cap B\cap C\cap D)=P(A)\times P(B)\times P(C)\times P(D)

Substitute the given values.

P(A\cap B\cap C\cap D)=0.93\times 0.93\times 0.95\times 0.92

P(A\cap B\cap C\cap D)=0.7559226

P(A\cap B\cap C\cap D)\approx 0.756

Therefore, the probability that the machine works properly is 0.756.
