an edge of cube a is 8 inches and an edge of cube b is 5 inches to the nearest tenth how many times greater is the volume of cube a than cube b

Answers

Answer 1

Answer: the areas of the cubes are
$a = {8}^(3) = 512 \n \n b = {5}^(3) = 125$

so the answer is
$512 / 125 = 4.1$

good luck

The model y = 500(1.035)^x, indicates the value of an investment, where x is the number of whole years. What's the growth factor (the ratio from one year to the next)?

Answers

Given:
model y = 500(1.035)^x is the value of the an investment after x years.

the growth factor of this model is 1.035

Let us assume that x = 3 and x = 2

y = 500(1.035)² = 500 (1.07) = 535
y = 500(1.035)³ = 500 (1.11) = 555

growth factor = 555 / 535 = 1.037 or 1.035

Answer:

first answer:-1.75

second:-15.75

third:-40.25

Step-by-step explanation:i am too lazy srry

Final answer:

The constant of proportionality is 1.75 inches per hour. The change in water level at 9 hours of draining is 15.75 inches, and at 23 hours of draining it is 40.25 inches.

Explanation:

The constant of proportionality represents the rate at which the water level is changing over time. To find the constant of proportionality, we can use the formula: constant of proportionality = change in water level / number of hours. Comparing the data in the table, we can find that when the number of hours is 2, the change in water level is 3.5. Therefore, the constant of proportionality is 3.5 / 2 = 1.75 inches per hour.

Next, to find the change in water level at 9 hours, we can multiply the number of hours by the constant of proportionality: 9 x 1.75 = 15.75 inches. Similarly, for 23 hours, the change in water level is 23 x 1.75 = 40.25 inches.

Is sec (11 pi/6) equal to (2 sqrt 3/3)?

Answers

$sec (11 \pi )/(6)= (1)/(cos (11 \pi )/(6) )$
Than: $cos (11 \pi )/(6)= ( √(3) )/(2)$
$(1)/( ( √(3) )/(2) ) = (2)/( √(3) ) = (2 √(3) )/(3)$
Answer:Yes, it is equal.

Yeap. sec (11pi/6) = 1/cos(11pi/6), verifying by calculator, you will get 1.1547, which is the value of 2 sqrt3/3
