What is the area of a rectangle with side lengths of 5 12 foot and 2 3 foot
vazorg [7]

Answer:

3 2/3ft²

Step-by-step explanation:

Area of a rectangle = Length × Width

Given

Length = 5 1/2 foot

Width = 2/3foot

Substitute

Area of the rectangle = 5 1/2 × 2/3

Area of the rectangle = 11/2×2/3

Area of the rectangle = 22/6

Area of the rectangle = 11/3

Area of the rectangle = 3 2/3ft²

Determine if the triangles, ΔYPQ and ΔNPD, are similar. If so, identify the similarity criterion.
pav-90 [236]

Answer:

The answer to your question is A) they are similar because of AA criterion

Step-by-step explanation:

- ∠ QYP is ≅ to ∠ DNP           given

- ∠ QPN is ≅ to ∠ DPN           vertical angles

- ∠ YQP is ≅ to ∠ NDP            if two angles are congruent third angle

                                                is also congruent.

Conclusion

ΔYPQ is similar to ΔNPD because of AA similarity.

The angles ∠CFE and ∠AFB are vertically opposite angles. Then the value of x will be 6.

<h3>What is an angle?</h3>

Angle is the space between the line or the surface that meets.  And the angle is measured in degree. For complete 1 rotation, the angle is 360 degrees.

Vertically opposite angle - When two lines intersect, then their opposite angles are equal.

We know that the angle ∠DFE is 90°.

Then the sum of the angle ∠CFD and ∠DFE will be

∠CFD + ∠DFE = 27° + 90°

∠CFD + ∠DFE = 117°

Then the angles ∠CFE and ∠AFB are vertically opposite angles. Then we have

∠CFD = ∠DFE

Put the values

21x - 9 = 117

    21x = 126

        x = 6

What is the length of the major axis of the conic section shown below?
sveticcg [70]

\dfrac{(x-2)^2}{49}+\dfrac{(y+5)^2}{36}=1

The equation of a elipse:

\dfrac{x^2}{a^2}+\dfrac{y^2}{b^2}=1

The length of the major axis is equal 2a if a > b or 2b if b > a.

We have

a^2=49\to a=\sqrt{49}=7\\\\b^2=36\to b=\sqrt{36}=6\\\\a > b

therefore the length of the major axis is equal 2 · 7 = 14.
