Step-by-step explanation:
Answer:
Step-by-step explanation:
u=6i-j
v=7i-4j
u.v=|6i-j||7i-4j| cos α,where α is the angle between u & v.
(6i-j).(7i-4j)=√(6²+(-1)²)√(7²+(-4)²) cos α
(6)(7)+(-1)(-4)=√37√65 cos α
42+4=√37√65 cos α
[tex]\cos \alpha =\frac{46}{\sqrt{37} \sqrt{65} } \\\alpha =\cos^{-1}\frac{46}{\sqrt{37} \sqrt{65} } \approx 20.28^\circ \approx 20.3^\circ[/tex]

From this quation:
4m = -32
We need to get m, so we can divide both sides by 4:
4m / 4 = -32 /4
m = -8
You can try to replace it to see if it's correct:
4 * 8 = -32

L=length; W=width.
L-2W=1
L=2W+1
P=2(L+W)
62in=2((2W+1)+W)
31in=3W+1
30in=3W
10in=W
The width is 10 inches.
L=2W+1=2(10in)+1=20in+1in=21in
The length is 21 inches.
Proof ;)
P=2(L+W)
62in=2(21in+10in)
62in=2(31in)

What percent is 45 of 72?
Answers
Answer:
32.4
32.4 is 45% of 72
Step-by-step explanation:
Solution:
What is 45% of 72?
Y is 45% of 72
Equation: Y = P% * X
Solving our equation for Y
Y = P% * X
Y = 45% * 72
Converting percent to decimal:
p = 45%/100 = 0.45
Y = 0.45 * 72
Y = 32.4

Step-by-step explanation:
The solution is found by dividing by the coefficient of y. Since that is a negative number, the sense of the comparison is reversed.
-8y ≥ 56
(-8y)/(-8) ≤ 56/(-8)

Triangle C
Step-by-step explanation:
Given
Triangle A, B, C and D
Required
Pick the odd triangle
From the attachment, we can see that:
A = Right angled triangle
B = Right angled triangle
C = Obtuse triangle
D = Right angled triangle
This is so because triangle C has one of its angles to be greater than 90 (i.e. 115) and other triangles (A, B and D) have an angle equal to 90, each.
Because C is obtuse and others are right-angled, then C is the odd triangle.

five sixths yards = inches
Answers
Answer:
Five sixths of a yard is 30 inches
Step-by-step explanation:
The perimeter of a rectangular field is 580 yards. The length is 30 yards more than the width. Find the length and width of the field (in yards).
Answers
2 L + 2 W = 580
W = L - 30
2( L - 30) + 2 L =580
2L - 60 + 2 L =580
4 L = 640
L = 160
W = 160-30= 130
160 × 2 + 130 × 2 = 580
