Your answer is D. All of these statements are true.
Answer:
<h2>60 days</h2>
Step-by-step explanation:
<h3>Step 1: First, since it is 1/6 pound twice a day, multiply by 2</h3>
1/6 x 2 = 1/3
<h3>Step 2: Divide 20 by 3 to get days that bag will feed the dog</h3>
20 ÷ 1/3 = 60
The bag will feed Nina's dog for 60 days.
I'm always happy to help :)
Answer:
Inequality: x + 6 ≤ 24
Solution: x ≤ 18
Step-by-step explanation:
<u>Plus</u>: "+" → to <u>add</u> something to something else
<u>Less than or equal to</u>: "≤" → the expression on the left side of the inequality sign is <u>smaller</u> than the expression on the right side of the sign.
Let x be the unknown number.
A number plus 6 is less than or equal to twenty-four:
x + 6 ≤ 24
To solve the found inequality, subtract 6 from both sides:
⇒ x + 6 - 6 ≤ 24 - 6
⇒ x ≤ 18
Therefore, the solution to the inequality is x ≤ 18. The unknown number x can be <u>any real number equal to or less than 18</u>.
To find the percent, we do 5/25. That gives the decimal 0.2, to change that to a percent, we move the decimal point 2 places to the right and add a % sign, giving 20%
Answer:
The scientist will measure ratio data
Step-by-step explanation:
In this experiment the scientist will measure different variables such as height of the plants, number of leaves or thickness of the stem among others, to compare the different results in the two environments (the one that has synthetic acid rainwater and that doesn't), so that he can determine the effect of the acid rain on a species of plants.
All the data that he will collect will be numbers for example in the day number 1 he measures the height of both plants and he gets that the plant that is in the environment with synthetic acid rainwater measures 1 cm while the one that is in the non-acidic synthetic rainwater measures 2 cm.
As the answers are numbers you can descard the nominal and the ordinal types of measures, and because the diference between the number matters (you know that 2 is bigger than 1) and also the zero means no growing so it determines the value scale, you can descard the interval type of measure, leaving the ratio measure which is a quantitative (the answer has numbers) type of measure in which you can define the order, the exact value between units and you can define an absolute zero.
