1) Speed = 12mph =12 mi/1 h =12 mi/ 60 min = 1/5 mi/ min
1 h= 60 min
t =20 min
Distance=speed*time =1/5 *20 (mi/min *min)= 4 mi
2) If he would bike for 15 min
Distance=speed*time
speed = distance/time = 4mi/15 min =4 mi :(1/4 h)=4*4= 16 mi/h
15 min =1/4 h
The best estimate would be D: 331 km
The Cube Root Of -343 is ( -7)

Answer:
32
Step-by-step explanation:
Angle E is congruent to angle C, so is the value required to make the sum of angles in triangle ABC be 180°.
∠E = 180° -118° -30° = 32°
The value of x is 32.
The figure shows that the polygon:
- Has 6 sides.
- Divided into 4 triangles.
- Total interior angle measure of 180°.
- Total measure of the interior angles of this polygon is 720°.
<h3>What is the polygon about?</h3>
The polygon has sides of: AB, BC, CD, DE, EF, FA.
So, this means that they have 6 sides and when you look at the diagram, this 6 sides can be divided into 4 triangle of which whose total interior will sum up to 180°.
Since there are 4 triangles and the interior is 180°, then to get the total measure of the interior angles of this polygon will be:
= 180 X 4 = 720
Therefore, one can say that the The figure shows that the polygon, has 6 sides, may be divided into 4 triangles, each of which will have a total interior angle measure of 180. Therefore, the total measure of the interior angles of this polygon is 720.
