The coordinates of the vertices of this triangle are;
The mapping for a dilation with a scale factor -4 about the origin is :
The coordinates of the vertices of the dilated triangle are:
We plot these points and connect them with straight lines.
If 21 is the final answer to the equation then x would be 9
0.45° in minutes is 27.36 minutes and in seconds is 21.6 seconds.
Why is it necessary to divide decimal degrees by 60 to obtain minutes and seconds?
- In a complete rotation, circles and spheres have 360 degrees. One degree is divided into sixty minutes, and one minute is divided into sixty seconds.
- You may see that your measurement is 91 full degrees plus 0.456 of a degree if you have 91.456 degrees.
How 0.45° is converted to equal minutes and seconds?
- To convert 0.456 degrees to minutes, multiply 0.456*60 and you will get the answer as 27.36 minutes. You now have a total of 27 minutes and 0.36 of a minute.
- To express 0.36 minutes seconds in decimal form, multiply 0.36*60 to get 21.6 seconds. You can round up to twenty two seconds because your decimal 0.6 is bigger than 0.5.

Answer:
I am pretty sure the answer is 4
Step-by-step explanation:
because 4 × 5 = 20 and 18 + 20 = 38
so if he rides 4 miles for 5 more days he will reach 38
