Answer:
11.75
Step-by-step explanation:
From the question above 8 is the difference of d and 3.75
We are required to find the value of d
d-3.75= 8
d= 8 + 3.75
d= 11.75
Hence the value of d is 11.75
Answer:
840.32
Step-by-step explanation:
10 quarters to 12 dimes, to 16 nickels
10(0.25) to 12(0.1), to 16(0.05)
2.5 to 1.2, to 0.8
2.083 to 0.8
1.6664
First, lets transform the given vector into an unit vector (dividing by its module)
UnitVec = 4/5 i + 3/5 j
Then lets change this vector into a polar form
UnitVec = 1. with angle of 36.869 degrees taking as a reference the i vector
Then, the probem tells us that the vectors u and v make an angle of 45 degrees with UnitVec, so lets add+-45 to the vector in polar form
U = 1*[cos(36.869 +45)i + sin(36.869 +45)j] = 0.1414 i + 0.9899 j
V = 1*[cos(36.869 -45)i + sin(36.869 -45)j] = 0.9899 i - 0.1414 j
Answer:
is the answer.
In decimal y = 43.71
Step-by-step explanation:
Given:
y varies directly with x .
Also x = 7 when y = 18
To Find:
y = ? when x = 17
Solution:
y varies directly with x .
i.e. y is directly proportional to x
∴ 
Where
k = constant of proportionality {Remain Same}
First we will find constant of proportionality k,
∴ When x = 7 and y = 18 we have
∴ 
Now when x= 17 and 
we have
∴
∴
