Answer:
![2.75\%](https://tex.z-dn.net/?f=2.75%5C%25)
Step-by-step explanation:
To find what percentage a certain value is of another value, simply divide the first value by the second, respectively.
We want to find want percentage that 7,562.5 is of 275,000. Therefore, we will divide 7,562.5 by 275,000 to obtain a decimal:
![\frac{7,562.5}{275,000}=0.0275](https://tex.z-dn.net/?f=%5Cfrac%7B7%2C562.5%7D%7B275%2C000%7D%3D0.0275)
To convert from a decimal to a percentage, multiply by 100:
![0.0275 \cdot 100=\boxed{2.75\%}](https://tex.z-dn.net/?f=0.0275%20%5Ccdot%20100%3D%5Cboxed%7B2.75%5C%25%7D)
Answer:
initial speed: 240 m/h
Step-by-step explanation:
48 m/h is the current speed which is the 20% of X
x (20 / 100) = 48
20x = 4800
x = 4800/20
x = 240 m/h
Answer:
Angle 1 and Angle 2 are adjacent angles.
Step-by-step explanation:
when a line intersects with 2 (or more) parallel lines. then, of course, the intersection angle is the same with every of the intersected lines. otherwise they would not be parallel.
so,
7x - 10 = 60
7x = 70
x = 10
