Find the value of each variable round your answer to the nearest 10th

Vanyuwa [196]

Answer:

10 for x and y

Step-by-step explanation:

Because the triangle adds up to 30 deggrees

So... you want to take 4 out.

30- 4 = 24

Than...You want to divided 24 by 2.

And that equals 12

Than round 12's by tenth

Which equals 10

What are the vertices of A'B'C if ABC is dilated by a scale factor of 2?

malfutka [58]

The vertices of A'B'C' if A(0, 10), B(8, 6), C(4, 2) is dilated by a scale factor of 2 are;

C. A'(0, 20), B'(16, 12), C'(8, 4)

<h3>Which method can be used to find the vertices of A'B'C'?</h3>

Given that triangle ABC is dilated by a scale factor of 2, we have;

A'B' = 2 × AB

A'C' = 2 × AC

B'C' = 2 × BC

Length of AB = √((8-0)^2 + (6-10)^2) = 4•√5

Length of AC = √((4-0)^2 + (2-10)^2) = 4•√5

Length of BC = √((8-4)^2 + (6-2)^2) = 4•√2

By multiplying the given coordinates by the scale factor, we have;

A' = 2 × (0, 10) = (0, 20)

B' = 2 × (8, 6) = (16, 12)

C' = 2 × (4, 2) = (8, 4)

A'B' = √((16-0)^2 + (12-20)^2) = 8•√5

A'C' = √((8-0)^2 + (4-20)^2) = 8•√5

B'C' = √((16-8)^2 + (12-4)^2) = 8•√2

Therefore when we have;

A'(0, 20), B'(16, 12), C'(8, 4), we get;

A'B' = 2 × AB

A'C' = 2 × AC
B'C' = 2 × BC

The correct option is therefore;

C. A'(0, 20), B'(16, 12), C'(8, 4)

A survey was done that asked people to indicate whether they run or ride a bike for exercise. Based on the table, what is the pe

Pavel [41]

The table in correct format is attached below.

Total number of runners = n = 724 + 103 = 827
Number of Runners who do not bike = x = 103

Percentage of runners who do not bike = $\frac{x}{n}$ x 100%

$= \frac{103}{827}$ x 100%

= 12.5%

Thus, 12.5% of Runners do not ride bike for exercise

In the figure below, which term best describes point T?

Bezzdna [24]

The center of this triangle is created by intersection of altitudes of the triangle, so this point T is an orthocenter.

So, the answer is A.
