Answer: 100 minutes
Step-by-step explanation:
With the given information, we can use a proportion to figure out how long it would take for Jen to bike 30 miles.
![\frac{12mi}{40min} =\frac{30mi}{x} \\](https://tex.z-dn.net/?f=%5Cfrac%7B12mi%7D%7B40min%7D%20%3D%5Cfrac%7B30mi%7D%7Bx%7D%20%5C%5C)

Answer:
The scale factor for the resultant rectangle is
units.
Step-by-step explanation:
Given two rectangles with sides 3 units and 7.5 units.
We have to find the scaling factors so that we can obtain bigger rectangle of 7.5 units from smaller rectangle of 3 units.
Scale factor is defined as the ratio of corresponding side of given figure to the corresponding side of resulting figure.
That is ![\text{Scale factor}=\frac{\text{length of side of given figure}}{\text{length of side of resulting figure}}](https://tex.z-dn.net/?f=%5Ctext%7BScale%20factor%7D%3D%5Cfrac%7B%5Ctext%7Blength%20of%20side%20of%20given%20figure%7D%7D%7B%5Ctext%7Blength%20of%20side%20of%20resulting%20figure%7D%7D)
Here, ![\text{Scale factor}=\frac{\text{length of side of given rectangle }}{\text{length of side of resulting rectangle}}](https://tex.z-dn.net/?f=%5Ctext%7BScale%20factor%7D%3D%5Cfrac%7B%5Ctext%7Blength%20of%20side%20of%20given%20rectangle%20%7D%7D%7B%5Ctext%7Blength%20of%20side%20of%20resulting%20rectangle%7D%7D)
![\text{Scale factor}=\frac{3}{7.5}=\frac{2}{5}](https://tex.z-dn.net/?f=%5Ctext%7BScale%20factor%7D%3D%5Cfrac%7B3%7D%7B7.5%7D%3D%5Cfrac%7B2%7D%7B5%7D)
Hence, the scale factor for the resultant rectangle is
units.
Answer:
A= 150°
B=30°
C=150°
Step-by-step explanation:
Since a line is 180°, you can write an equation for C. C+30°=180° , from here use algebra to find C. The value of C will be 150°. When the value of C is 150° , since they're supplementary angles, the value of A will also be 150°.
Important thing to note:
The value of all these angles combined together is 360°.
