A certain type of cereal costs $3.79 for 19.5 ounces. What is the unit rate?Enter your answer, rounded to the nearest cent, in the box.

Answer:

400%

Step-by-step explanation:

Given :

The volume for 3-D polyhedral A is 200 cubic cm.

The volume for 3-D polyhedral B is 800 cubic cm.

To Find: how many times bigger is the volume of pyramid B than pyramid A?

Solution:

Since we are supposed to find how many times bigger is the volume of pyramid B than pyramid A.

⇒

⇒

⇒

⇒

Thus Option D is correct.

Hence the volume of pyramid B is 400% times bigger than pyramid A.

Answer:

1 and  4

Step-by-step explanation:

ANSWER

first is the geometric series

EXPLANATION

a geometric series is a sequence of numbers whose first term is non zero and each of the succeeding terms is equal to the Prcedding term multiply by a constant number.

if a = first term

and constant number = d

then

GP is given by

a,a r , a r^2 ,a r^3 .............and so on

in first

a = 1/2

and d = 1/2

and hence it is an GP

Answer:

constant of proportionality is

Step-by-step explanation:

The direct proportionality says that:

then the equation is in the form of:

.......[1]

where, k is the constant of proportionality.

As per the statement:

Given the ratio 2/5

i.e,

then using [1] we have;

⇒

or

Therefore, the constant of proportionality for the ratio of 2/5 is;

The "constant of proportionality" is the value that relates the two amountsExample: you are paid $20 an hour (continued)The constant of proportionality is 20 because:Earnings = 20 × Hours worked

This can be written:  y = kx

Where k is the constant of proportionality
