Enrique is measuring the mass of a flower petal. which unit of measurement should he use to eliminate the need to write value in scientific notation?

He would use gram as a unit of measurement to eliminate the need to write value in scientific notation.

Step-by-step explanation:

Since we know that

S.I. unit of mass is kilogram.

But the kilogram is used for heavier things.

To measure the mass of a flower petal, we need a smaller unit of mass.

Mass or weight of flower petal is based on its color and size.

The range of its mass is in between 40-80 grams.

Hence, he would use gram as a unit of measurement to eliminate the need to write value in scientific notation.

walter needs to make at least 5 more cookies but no more than 40. 5 ≤ x ≤ 40

step-by-step explanation:

20 ≤ x + 15 ≤ 55

subtract 15 from all parts

20-15 ≤ x + 15-15 ≤ 55-15

5 ≤ x ≤ 40

this means how many more cookies he has to make

walter needs to make at least 5 more cookies, but no more than 40 cookies; 5 ≤ x ≤ 40

the inequality is:

250c+180g≥950

step-by-step explanation:

let c denotes the number of days in a week   miyoko worked as a cryptographer.

and g denotes the number of days in a week she works as a geologist.

now we are given that she earns $250 for every day she works as a cryptographer,and earns $180 for every day she works as a geologist.

now miyoko's goal is to earn more than $950 this week.

hence, the inequality could be represented as:

250c+180g≥950
