The combined area of these three rooms is 189 ft².
Therefore we have the equation
4x + 3x + 2x = 189
9x = 189 |:9
x = 21 ft²
area of the kitchen = 4x = 4(21) = 84 ft²
area of the playroom = 3x = 3(21) = 63 ft²
area of the dinning room = 2x = 2(21) = 42 ft²

Explain how to use the missing pieces strategy to compare two fractions. Include a diagram with your explanation.
kozerog [31]
The missing pieces strategy is another method to compare two fractions. To tell which number is larger, you need to see which one is missing less. For example, you have 3/4 versus 4/5. Each of these fractions needs 1 to complete the whole. You need to subtract the numerator with one to compare them. For 3/4 we have 1/4 and for 4/5 we have 1/5. You know that if you complete 4/5 you will get 4. You know that 5 is greater than four. Therefore, 4/5 is larger than 3/4.

9-5 x+5-5

4=x

The domain is (2,4)

Answer:

\displaystyle m\angle AED=32.5^\circ

Step-by-step explanation:

<u>Angles in a Circle</u>

An exterior angle of a circle is an angle whose vertex is outside a circle and the sides of the angle are secants or tangents of the circle.

Segments AE and DE are secants of the given circle. They form an exterior angle called AED.

The measure of an exterior angle is equal to half the difference of the measure of their intercepted arcs.

Intercepted arcs in the given circle are AD=113° and BC=48°. The exterior angle is:

\displaystyle m\angle AED=\frac{AD-BC}{2}

\displaystyle m\angle AED=\frac{113^\circ-48^\circ}{2}=\frac{65^\circ}{2}

\displaystyle m\angle AED=32.5^\circ
