Answer:

x₁ = x₂ (corresponding angles are equal)

y₁ = y₂ (right angles)

z₁ = z₂

Since the angles in the first triangle are equal to the angles in the second triangle, the two triangles are similar.

Because they are similar, then the ratios of their corresponding sides are equal:

$\\\\\frac{9}{h} =\frac{11}{16}$

h = 9×16/11 = 144/11 = 13 1/11 = 13.09

Someone help?!.........

koban [17]

Answer: y = -2x + 16

Explanation:

Use point slope form:

(y1 - y) = m(x1 - x)

y1 = 6 and x1 = 5 and m = -2

6 - y = -2(5 - x)
6 - y = -10 + 2x
-y = 2x - 10 - 6
-y = 2x - 16
y = -2x + 16

This is a bonus question

Elena L [17]

Answer:

10,500

Step-by-step explanation:

See this as 2 rectangles: a box of water (28cm), and another box with the height you want (35cm)

Area of Rectangle = lwh

For the water;

50 x 30 x 28= 42000

As for the needed volume:

50 x 30 x 35 = 52500

To find how much more water, subtract the smaller volume from bigger volume.

10500 should be the final answer

What's the standard equation of the circle with the general equation x2 + y2 + 4x – 2y – 20 = 0? answers: 1) (x + 2)2 + (y – 1)2

gizmo_the_mogwai [7]

Answer:

4). (x + 2)^2 + (y - 1)^2 = 25.

Step-by-step explanation:

x^2 + y^2 + 4x - 2y - 20 = 0

x^2 + 4x + y^2 - 2y = 20

Completing the square on the x and y terms:

(x + 2)^2 - 4 + (y - 1)^2 - 1 = 20

(x + 2)^2 + (y - 1)^2 = 20 + 4 + 1

(x + 2)^2 + (y - 1)^2 = 25.

A spinner has 10 10 equal-sized sections. Six Six of the sections are purple purple. a. What is the probability that the spinne

borishaifa [10]

Answer:

P(Spinner lands on purple section) = 0.6 = 60%

Step-by-step explanation:

We are given the following in the question:

Number of sections = 10

Number of purple sections = 6

$\text{Probability} = \displaystyle\frac{\text{Number of favourable outcomes}}{\text{Total number of outcomes}}$

a) probability that the spinner will land on purple purple

P(purple) =

$=\dfrac{6}{10} = 0.6$

0.6 is the probability that the spinner will land on purple purple.

b) Interpretation of probability

$0.6\times 100\% = 60\%$

There is a 60% chance that the spinner will land on purple color.
