meriva

8/11 of what = 16

8/11x = 16
x = 16 * 11/8
x = 176/8
x = 22......so there are a total of 22 fish in the tank

I don't really know on this one. I'm thinking it's because if T kept going it would go into a 3rd quadrant but I'm not too sure.

enyata [817]

That is correct since the line in T is not straight it would eventually hit the third quadrant

7.7.4 Practice: Modeling: Similarity Theorems will give brainliest

Nimfa-mama [501]

Similar triangles may or may not be congruent

The height of the peak is 72 feet
The triangles are similar by AA similarity postulate

<h3>How to determine the similarity statement</h3>

First, we determine the height of the peak using the following equivalent ratios

P B : B M = T F : F M

So, we have:

$PB : 20ft= 6ft : 1ft\ 8in$

Express the units in inches

$PB : 240in= 72in: 20in$

Express as fractions

$\frac{PB}{240} = \frac{72}{20}$

Multiply both sides by 240

$PB = \frac{72 * 240}{20}$

$PB = 864$

Express as feet

$PB = 72 feet$

So, the height of the peak is 72 feet

The ratio also means that the triangles are similar by AA similarity postulate

Please help I will give 10 points

Answer:

x = 13.75

Step-by-step explanation:

a right-angled triangle.

so, we use Pythagoras

c² = a² + b²

where c is the Hypotenuse (the side opposite of the 90 degree angle).

so, in our case

17² = 10² + x²

289 = 100 + x²

189 = x²

x = 13.75
