Answer:

39 seats are not being used in the auditorium.

Step-by-step explanation:

We have bee given the total number of seats:

In middle school auditorium are 342

Seats used  by teachers are 75

And seats used by students are \frac{2}{3}\text{of the seats}

And \frac{2}{3}\cdot 342=228seats used  by students

That means  228+75=303 seats are used

We need to calculate seats not being used which is equal to

Total seats minus  seats used =342-303 =39 seats remain unused.

A scale on a bike path shows that 3 inches represents 5 miles. How many inches on the map are equal to 30 miles
PtichkaEL [24]

Answer:

18 inches.

Step-by-step explanation:

If the ratio for inches to miles is

\frac{3}{5},

then you multiply the top and bottom by 6 to get to 30. This gets the numerator to 18 inches.

xxMikexx [17]

Answer:

20, 31, 33, 35, 55, 57, 58, 59, 72, 73, 79, 86, 87, 88

Step-by-step explanation:

The data set is split by digit. So 2|0 becomes 20. 5|5 becomes 55. Using this method, the data set is

20, 31, 33, 35, 55, 57, 58, 59, 72, 73, 79, 86, 87, 88

∆DEF≈~ STU. If TU-=8, SU = 10, and ST= 4, what is the length of -DE-?
Morgarella [4.7K]

Answer:

if that statement is true, then DE=ST, and ST=4 so your answer should be <u>DE=4</u>

Explanation:

you can tell that they are even from looking at the first statement, it states <u>DE</u>F=<u>ST</u>U, emphasizing on the DE=ST part, it gives your the answer right there because ST=4

QUESTION IS DOW BELOW 5 POINTS EACH PLEASE HELP PLEASE HELP PLEASE HELP

The central angle in the circle is ∠DAC,major arc is BED, minor arc is ADC and BC=(5π*BD)/18.

Given that BD is diameter of the circle and angle BAC is 100°.

We are required to find the central angle, major arc, minor arc, m BEC, BC.

Angle is basically finding out the intensity of inclination of something on the surface.

In the circle central angles are many like BAC and CAD. We can write CAD as DAC also.

Major arc of a circle is that arc whose length is larger than all other arcs in the circle.

In our circle the major arc is arc BED.

Minor arc of a circle is that arc whose length is smaller.

In our circle the minor arc is arc ADC.

We know that arc's length is 2πr(Θ/360)

In this way BC=2π*(BD/2)*100/360

=(5π*BD)/18

We cannot find angle BEC.

Hence the central angle in the circle is ∠DAC,major arc is BED, minor arc is ADC and BC=(5π*BA)/18.
