Answer:
She divided the coefficients incorrectly
Step-by-step explanation:
A. She divided the coefficients incorrectly.
B. She added the exponents instead of subtracting them.
C. She divided the coefficients instead of subtracting them.
D. She subtracted the exponents instead of dividing them.
Correct calculation:
3x³/12x^-2
= 3x³ ÷ 12x^-2
= 3x³ ÷ 1/12x²
= 3x³ × 12x²/1
= 36x^5
Tyna's calculation:
3x³/12x^-2 = x/4
To answer this question I would need the original coordinates. Were you given a picture or coordinates of the original triangle?
Answer:
independent and explanatory
Step-by-step explanation:
In a study, an independent variable may be defined as the variable that does not affect the other variables in the study when it is changed. Thus a variable is said to be independent when it is not affected by the any other variable in the study.
Whereas, an explanatory variable can be manipulated or changed by the experimenter. It is the variable that is not independent for certain variables.
Thus in the context, the scatterplot showing the total precipitation and the percent of the people who tested positive for the malaria test. The precipitation from the graph is the independent as well as the explanatory variable.
Answer:
0.8 yards or 28.8 inches
Step-by-step explanation:
I always turn fractions into decimals because it is easier to figure it out and simpler.
So 1/5 would be 2/10 because you multiply the whole thing by 2 to make the denominator 10 so you can turn it into a decimal.
So the decimal is 0.2
You would divide 7.2 by 9 to get 0.8 yards which is 28.8 inches.
Answer:
The numbers of toys per hour is 60c/m toys
Step-by-step explanation:
* Lets explain how to solve the problem
- an algebraic expression is an expression formed from integer
constants, variables, and the algebraic operations like addition,
subtraction, multiplication, division
- Ex: 5x² − 7xy + a is an algebraic expression
* Lets solve the problem
- Kevin makes c toys in m minutes
∴ His rate is c/m toy per minute
- To find the number of toys in one hour multiply his rate by the time
in minutes
∵ In one hour there are 60 minutes
∵ His rate = c/m (toy/minute)
∵ The time is 60 minutes
∴ The number of toys = c/m × 60 = 60c/m toys
∴ The numbers of toys per hour is 60c/m toys
