<span><span>if one angle is x and the ratio of 1 : 4 : 7, means second angle is 4x and third angle is 7x
since the sum of all three angles in a triangle is 180 degrees, we have
x+4x+7x=180
12x = 180
x = 15
then
4x = 60
7x = 105
The angles are 15°,60 °, and 105 °.</span><span>
Therefore, yes.</span></span>

.125 should be your answer. Have a Great Day!
Step-by-step explanation:
Answer: a) b) c) d)
Step-by-step explanation:
Since f is an exponential function.
So, it is expressed as
Here f is the present value
p is the initial value
r is the rate of growth per time period
t is the time period.
(a) b represents the 1-unit growth factor for f.
(b) c represents the n n-unit growth factor for f.
(c) d represents the m m-unit growth factor for f.
Write a formula that expresses c in terms of b.
Since
Hence, a) b) c) d)
