At the start of the year, 15 chameleons were introduced into a zoo. The population of chameleons is expected to grow at a rate of 41.42% every year. The function below models the population of chameleons in the zoo, where x represents the number of years since the chameleons were introduced into the zoo. A. The average rate of change in the population between year 4 and year 6 was 41 more than the average rate of change in the population between year 6 and year 8. B. The average rate of change in the population between year 2 and year 4 was approximately half the average rate of change in the population between year 4 and year 6. C. The average rate of change in the population between year 4 and year 6 was the same as the average rate of change in the population between year 6 and year 8. D. The average rate of change in the population between year 2 and year 4 was approximately double the average rate of change in the population between year 4 and year 6.

A punch recipe calls for orange juice and pop in the ratio of 2:5 the recipe requires 1L of Pop to serve 7 people a) how much orange juice is needed for 7 people?
b)about how much orange juice and pop do you need to serve 15 people? 20 people?
plz say how you answered this

Answers

O : P => 2 : 5

(a)    1 liter of pop to serve 7 people

=>           5 units = 1

               1 unit = 1 / 5

Orange juice => 2 units

Hence, Orange juice needed is 2 * 1 / 5 = 0.4 liters

 

(b)    If 1 liter of pop is needed to serve 7 people, then we will need (1 / 7) * 15 for 15 people

i.e. 2.14 liters

 

As the ratio of O : P = 2 : 5,

               5 units = 2.14

               1 units = 2.14 / 5

 

For Orange juice, we will need 2 * 2.14 / 5 = 0.856 liters for 15 people

Simplify 15/20 into 3/4

then 3 divided by 4= 0.75

the answer is 0.75
Howdy there! ;) The answer to your question is 0.75. I got the answer because you divide 15 and 20( 15/20) So simplify if you want to. 15/5=3 20/5=4 equals 3/4 there are 4 25's in a hundred 25,50,75,100 so since 3/4 is three then it would be 0.75.


Hope I helped! :D

PLEASE HURRYA 5 inch × 7 inch photograph is placed inside a picture frame. Both the length and width of the frame are 2x inches larger than the width and length of the photograph. Which expression represents the perimeter of the frame?

Answers

Answer:

48in

Step-by-step explanation:

We know that the photograph is

Width photo = 5in

Lenght photo = 7in

The length and width of the frame are 2x inches larger than the width and frame of the photograph so:

Width frame = 5in x 2 = 10 in

Lenght frame = 7in x 2 = 14 in

The perimeter is the distance around a two-dimensional shape. Then, the perimeter of the frame is:

Perimeter = 10 in + 14 in + 10 in + 14 in = 48in

A survey found that 3 out of 7 people in a community job on a regular basis. If there are 3150 people in the community, What is the reasonable prediction for the number of people who would jog regularly?

Answers

The requried reasonable prediction for the number of people who would jog regularly in the community is 1350.

What is proportionality?

Proportionality is the relationship between two or more sets of values, and it describes how these values are related to each other.

If 3 out of 7 people jog on a regular basis, then the fraction of people in the community who jog on a regular basis is:

3/7

To predict the number of people who would jog regularly in the community, we can multiply this fraction by the total number of people in the community:

(3/7) * 3150 = 1350

Therefore, a reasonable prediction for the number of people who would jog regularly in the community is 1350.

#SPJ3
so 3150÷7=450 and then multiply 450×3= 1350. So 1350 people who jog regularly
