In this diagram, bac~edf. if the area of bac= 6 in.², what is the area of edf? PLZ HELP PLZ PLZ PLZ
NemiM [27]

Answer:

2.7 in²

Step-by-step explanation:

Area of ∆BAC : ∆Area of EDF = BC² : EF² (based on the area of similar triangles theorem)

Thus:

6 in^2 : x in^2 = (3 in)^2 : (2 in)^2

\frac{6}{x} = \frac{3^2}{2^2}

\frac{6}{x} = 2.25

\frac{6}{x}*x = 2.25*x

6 = 2.25x

\frac{6}{2.25} = \frac{2.25x}{2.25}

2.67 = x

Area of ∆EDF = 2.7 in²

Sara works for 40 hours a week. She attends meetings for 0.28 of the time she is working. How much time does Sara spend at meeti
Roman55 [17]

Answer:

11.2 hours or 11 hours 12 minutes

Step-by-step explanation:

In this question, we are to calculate the amount of time spent by Sara in attending meetings weekly.

In the question, we are made to understand that she attends a meeting at a rate of 0.28 multiplied by the total amount of time she works.

To get the time she attends the meeting, we only need to multiply the decimal by the number of hours she works

Mathematically that would be 0.28 * 40 = 11.2 hours per week

We might take it further to get the time in the format of hours and minutes. That would be 0.2 * 60 yo convert the hours to minutes. This gives 12 minutes .

She attends meeting 11 hours 12 minutes per week

A map distance of 5 inches represents 200 miles of actual distance . Suppose the distance between two cities on the map is 7 inc
Naily [24]
\frac{5}{200} = \frac{7}{x} \\ 5x = 1400 \\ x = 280

therefore, the actual distance is 280 miles.
