Answer:

Step-by-step explanation:

Triangle ABC is a right angle triangle which is made up of 2 right angle triangles.

To determine y, we would apply Pythagoras theorem which is expressed as

Hypotenuse² = opposite side² + adjacent side². Therefore

136² = y² + 120²

18496 = y² + 14400

y² = 18496 - 14400 = 4096

y = √4096 = 64

To determine z,

255² = z² + 120²

65025 = z² + 14400

z² = 65025 - 14400 = 50625

z = √50625 = 225

What's the answer to this question and how do I solve it?
Katyanochek1 [597]

Answer:

80 gummy bears are in 4 servings.

Step-by-step explanation:

2 servings=40 gummy bears

3 servings=60 gummy bears

<u>40</u>+20=<u>60</u>

Add 20 gummy bears for every serving.

5 servings=100 gummy bears

100-20=<u>80 gummy bears are in 4 servings</u>



OR you can also do:

40÷2=20 gummy bears are in each serving

So, 4x20=<u>80 gummy bears are in 4 servings</u>
