Find the missing dimension.

Mathematics
1 answer:
Alecsey [184]2 years ago
4 0

Answer:

2 m

Step-by-step explanation:

Here the area and the lengths of the two parallel sides of this trapezoid are given:

A = 7m^2, b1 = 3 m and b2 = 4 m.  What's missing is the width of the trapezoid.

First we write out the formula for the area of a trapezoid:

       b1 + b2

A = --------------- * w, where w represents the width of the figure.

             2

We need to solve this for the width, w.  Multiplying both sides of the above equation by

     2

------------

b1 + b2

results in

 2A

------------ = w

b1 + b2

Substituting 7 m^2 for A, 3 m for b1 and 4 m for b2 results in

        2(7 m^2)           14 m^2

w = ------------------ = ---------------- = 2 m

        (3 + 4) m             7 m

The missing dimension is the width of the figure.  This width is 2 m.

5. ALGEBRA Refer to the figure in
mamaluj [8]

The value of x that satisfies all the expressions of the system of linear equations is 20.

<h3 /><h3>Procedure - Determination of a variable associated to a pair of corresponding angles</h3>

According to the figure, angles 1 and 5 are <em>corresponding</em> angles between two <em>parallel</em> lines, therefore we have the following equivalence:

4\cdot x + 40 = 120 (1)

After some algebraic handling we find the value of x:

4\cdot x = 80

x = 20

The value of x that satisfies all the expressions of the system of linear equations is 20. \blacksquare

<h3>Remarks</h3>

There is a missing figure for the statement, we proceed to include it below after some research.

Find the measure of the smaller angle formed by hands of a clock at the following time.
goldfiish [28.3K]
A clock is a circle which is 360 degrees.

There are 12 hours -----> 360/12 = 30 degrees.

Going clockwise, add 30 degrees for every hour the hour hand is at.

There are 60 minutes -----> 360/60 = 6 degrees.

Add 6 degrees for every minute the minute hand is at.

Find position of both hour hand and minute hand, then take the difference.

Time is 5:15.
Hour hand is at 5 plus 15/60 or 5.25.
Multiply by 30. 30*5.25 = 157.5

Minute hand is at 15.
Multiply by 6. 15*6 = 90

157.5 - 90 = 67.5 degrees.

It would be D because the equation just seems flipped, but the requirements of x are fulfilled.
