You are so kind❤️❤️❤️❤️ thank you
Answer:
8.40
Step-by-step explanation:
so I put 20x6.75/100 which = 1.35 and 4.5x6.75/100 which = .30 and I added .30 to 6.75 which = 7.05 and then I added 1.35 to that and got 8.40
so I got $8.40
Answer:
152.7 yd
Step-by-step explanation:
I presume that there is a fence around the perimeter and separating the various plots.
AG = BF = CE = 18 yd
GH = DE = 12 yd
EO² = DE² + DO²
1 5² = 12² + DO²
225 = 144 + DO²
81 = DO²
DO = 9
BC = DO = EF = 9 yd
AC = DH = EG = 17 yd
AO² = AB² + BO² = 8² + 6² = 64 + 36 =100
AO = √100 = 10 yd
CO² = BC² + BO² = 9² + 6² = 81 + 36 = 127
CO = √127 yd
GO² = FG² + FO² = 8² + 12² =64 + 144 = 208
GO = √208 = 4√13 yd
Fencing needed
= (AC + DH + EG) + (AG + BF + CE) + AO + CO + EO + GO
= (3 × 17) + 3 × 18) + 10 + √127 + 15 + 4√13
= 51 + 54 + 25 + 11.27 + 14.42
= 152.7 yd
Answer:
B)
Step-by-step explanation:
The value is the same as since the negatives cancel out to make a positive.
Option A is incorrect since the overall value of the term would be negative. Option B however is correct since there will not be a negative value in the denominator of a fraction and thus it cancels out with the negative in front of the fraction to produce the value of which is the same as the expression given in the question, thus it is option B.
Answer:
54.74°
Step-by-step explanation:
Draw a well labelled cube to have a better representation of the question.
A cube is 3-dimensional, therefore it will have coordinates in x,y and z axis. The diagonal of a cube is from one corner to another corner.
Assuming that cube is unit cube, we need to find n angle at one of its edges will make with the diagonal.
I choose the the diagonal and one edge with the unit vector (1,0,0) and (1,1,1).
a = (1,1,1)
b = (1,0,0)
To calculate the angle between two vectors,
a.b = |a||b|cosθ
For simplicity, calculate the dot product, and the magnitudes. Then we will substitute the values of the dot product, and the magnitudes of the vectors to solve for the angle.
Calculating the dot product
a.b = (1,1,1) . (1,0,0)
= (1 × 1) + (1 × 0) (1 × 0)
= 1
Calculating the magnitudes
1. Magnitude of (1,1,1)
2. Magnitude of (1,0,0)
Calculating the angle between the two vectors
