Answer:
153.2 cm
Step-by-step explanation:
So, Annapolis and San Diego are 2298 miles apart, if every 30 miles is equivalent to 2 cm, we need to find how many cm are equivalent to 2298. An easy way is to find the equivalence in cm if 1 mile, lets do this.
If 2 cm are 30 miles, we can say that:
2cm = 30 m
If we divide both sides by 30, we get 1 mile on the right side:
2/30 cm = 1 m
1/15 cm = 1 m
0.06667 = 1 m
Then, 1 mile is equivalent to 1/15 cm or 0.06667 cm. Thus, we need to multiply this value for 2298 to find out what is the equivalence in cm for 2298 miles:
(1/15)*2298 = 153.2 cm
So, we get that San Diego and Annapolis will be at a distance of 153.2 cm, or 1.532 meters.
I hop its understandable!
Answer:
The scale factor is 1.25 !
Step-by-step explanation:
Take the sides of one triangle and divide them by the sides of the other triangle.
45/36 = 1.25
30/24 = 1.25
35/28 = 1.25
Perpendicular means opposite and reciprocal (in reference to the slope).
The opposite of 1/2 is -1/2. The reciprocal of -1/2 is -2.
Now we know the slope we can plug the point they gave us into the X and Y positions to solve for b (in the point (2, 3) there is a X - Value (2) and a Y-value (3)
y= -2x+b
3= -2(2)+b
3= -4+b
1=b
Now we plug b and the slope in the generic y=mx+b equation:
y= -2x+1
4x+5x+1=10 —> 9x=9 —> x=1 :) hope i could help!
