Answer:

1.30g

Step-by-step explanation:

The mass of 8 seed pods is equal to 10.4g.

10.4g = 8 pods

Total mass / Total pods = Individual pod weight

10.4g / 8 pods = 1.30g per pod

Lets check our work to confirm:

1.30g x 8 pods = 10.4g

What is the constant rate of change of (5,80) (4,64) and (6,96)

sveticcg [70]

Answer:

Step-by-step explanation:

The existence of the constant rate of change is given the ratio of y to x is the same. Then:

$k_{1} = \frac{80}{5}$

$k_{1} = 16$

$k_{2} = \frac{64}{4}$

$k_{2} = 16$

$k_{3} = \frac{96}{6}$

$k_{3} = 16$

In consequence, the constant rate of change is 16.

Answer:

A. 29 feet

Step-by-step explanation:

Use cos to find the hypotenuse

cos = adj/hp

0.64 = 20/hyp

hyp = 20/0.64

hyp = 31.25

---------------------------

Use Pythagorean Theorem to find the height of tree above eyes

a² + b² = c²

a² + 20² = 31.25²

a² = 31.25² - 20²

a² = 576.5625

a = 24 (to the nearest foot)

-------------------------------

Finally add in the eye height

h = 24 + 5

h = 29 feet
