Answer:

Ellipse

Step-by-step explanation:

From the given information:

Suppose the plane cuts the cone in such a manner that the plane is neither perpendicular nor parallel to the axis and also the angle of intersection is greater than the generator angle.

Then the conic section formed is an Ellipse.

a trapezoid with base measure of 23 km and 29km an area of 390km . find the height of the trapezoid.
cupoosta [38]
Hello!

To find the area of a trapezoid you use the equation

A =  \frac{a+b}{2} h

Put in the values you know

390 =  \frac{23+29}{2} h

Add

390 = \frac{52}{2} h

Divide

390 = 26 * h

Divide both sides by 26

15 = h

The answer is 15km

Hope this helps!

4. 6940 / 10^{2} = 69.4

5. 3/4 x 5 = 3.75 or 3\frac{3}{4}

6. (2 x 7) - (2 x 5) = 4

7. The area is \frac{6}{7}

8. 70 - (20-13) would probably work

Please give my brainliest if I helped!

8s + 9 = 7s + 6 <br>s= ? ​
denis-greek [22]

Answer:

s = -3

Step-by-step explanation:

8s + 9 = 7s + 6

Subtract 7s from each side

8s-7s + 9 = 7s-7s + 6

s+9 = 6

Subtract 9 from each side

s + 9-9 =   6-9

s = -3
