Answer:
Variables:
→ The number of hours the worker worked
→ The number of shirts the worker made.
System fo equations:
Step-by-step explanation:
Let be the number of hours the worker worked and the number of shirts the worker made.
Since:
- Jason must pay the worker $25 per hour (which can be represented with
). - He must pay $1.75 per shirt for material costs (which can be represented with
). - The total expenses were $270.
You can write the following equation:
Knowing that the worker created an average of 5 shirts per hour, you can write the other equation:
Therefore, with this equations you can set up the following system of equations, which could be used to determine the number of hours the worker worked and the number of shirts the worker made:
Answer:
x=t/5
Step-by-step explanation:
5x=t
multiply both sides by 5 to make x the subject
x=t/5
Answer:
- A cross-sectional study.
Step-by-step explanation:
A Cross-sectional study is demonstrated as the type of observational study in which the data or a representative subset of a population collected at a particular point in time is analyzed.
As per the given details, the observational study conducted by the research company would exemplify 'a cross-sectional study' as it aims to evaluate the data('viewing habits of about 50005000 households) collected at a specific point in time i.e. 'today' in order to 'determine the proportion of households tuning to a particular sports program.'
Answer:
x = 24
Step-by-step explanation:
To find the value of x, create a proportion. A proportion is two equal ratios for similar figures. The two triangles are similar because they are the same shape but not the same size. Create ratios between corresponding sides of figures.
To solve for x, cross multiply:
44.8(35) = (x+4)(56)
1568 = 56x + 224
1344 = 56x
24 = x
