Answer:
The expression is equal to 8
Step-by-step explanation:
This is the question in proper
6t−20−32u
When u= 1/4 t= 6
We were given this, 6t−20−32u then we were given the value of u= 1/4 and that of t= 6.
All we need here is to substitute u= 1/4 t= 6 into 6t−20−32u then evaluate it as follows
6(6)-20-32(1/4)
6×6=36
32×(1/4)=8
Then merge it together and calculate it we have
=36-20-8=8
Answer:
61.4°
Step-by-step explanation
Given
Length of the ramp = 23ft = hypotenuse
Base of the ramp = 11ft = Adjacent
Required
Angle of elevation x
Using the SOH CAH TOA identity
Cos theta =adj/hyp
Cos x = 11/23
Cos x = 0.4782
x = arccos0.4782
x = 61.42°
Hence the angle of elevation is 61.4°
2,4,6,8,10,0,0,0,0,0,1,4,9,16,25,1,2,3,4,5
8x7=56
56+103=159
