1 answer:
MA_775_DIABLO [31]3 years ago
8 0

Step-by-step explanation:

step 1. there are 3 right triangles!

step 2. 8/6 = 6/x (definition of right triangle with an altitude)

step 3. 8x = 36 (cross multitude)

step 4. x = 9/2 (divide both sides by 8)

step 5. 6^2 + x^2 = y^2 (pythagorean theorem)

step 6. 6^2 + (9/2)^2 = y^2

step 7. 144/4 + 81/4 = y^2

step 8. 225/4 =y^2

step 9. y = 15/2 = 7.5.

Answer:

3 minutes

5 minutes.

Step-by-step explanation:

It is given that, Amelia can wash 8 plates in 24 minutes.

So, if this rate remains constant then 1 plate will be washed in \frac{24}{8} = 3 minutes.

Again, it is given that, Amelia bakes 12 cookies in 60 minutes.

So, if this rate also remains constant then she will bake 1 cookie in \frac{60}{12} = 5 minutes. ( Answer )

Help me please with explanation
8_murik_8 [283]

Step-by-step explanation:

angle AOB = x+3

angle AOC = 2x + 11

angle BOC = 4x-7

angle AOC = angle AOB + angle BOC

=> 2x +11 = (x+3) + (4x-7)

2x +11 = 5x - 4

=> 3x = 15

x = 5

subst x = 5 in the given formulas

angle AOB = x +3 =8

angle AOC = 2x + 11 = 21

angle BOC = 4x - 7 = 13
