Answer:
1. h=1.5d. 2. 30cm in 20 days
Step-by-step explanation:
2. 20×1.5
Answer:
2
Step-by-step explanation:
For the image, you just multiply the numbers to find the sides
(4*2=8 5*2=10 3*2=6)
Then find out how you went from the preimage to the image.
4 * 2 = 8 etc.
Answer:
12
Step-by-step explanation:
it’s 12 because 4 x 3 = 12
The distance between the friends at the end of one hour can be found from the Pythagorean theorem to be
.. d = √(40^2 +35^2) = √2825 = 5√113 ≈ 53.15 . . . . miles
Since the friends are continuing in the same directions at the same speeds, their distance apart will increase by this amount each hour.
distance = t*5√113 . . . . miles after t hours
Angle of elevation.
<span>On the first, the 456 is the opposite leg and the 837 is the adjacent to the angle of elevation so use tangent (from soh cah toa); x = the angle measure </span>
<span>tan x = 456/837 </span>
<span>inverse tan (456/837) = x so do that on your calculator (be sure it is in degree mode). </span>
<span>Then for Ramsey, 1453 is opposite leg and 2960 is adjacent so you have tan x = 1453/2960 and do like the first one.</span>
