Answer:
=5.1 units
Step-by-step explanation:
To use the sine rule to find the length of c we first need to find the angle at C.
C=180-(13+12)
C=180-25
C=155°
a/Sin A=c/Sin C
Calculating for the value of c using the sine rule:
12/Sin 13=c/Sin 155
c=12 sin 155
=5.07 units
Thus to 1 decimal places, the value of c is 5.1 units.
Answer:
<u>1.16 m (approximately)</u>
Step-by-step explanation:
Let x be the width of the path.
Total area = (5+2x)(3+2x) = 39
Expand and simplify
4x²+ 16x+15-39 = 0
4x² + 16x - 24 = 0
Simplify
x² + 4x -6 = 0
Rational factoring does not work, so use quadratic formula
x = +/- sqrt(10) -2
= 1.16 or -5.16 (reject)
= <u>1.16 m (approximately)</u>
Answer:
10408 ft
Step-by-step explanation:
convert miles to ft
4 miles/hr * 5280 ft/ mile = 21120 ft/hr
convert hr to min
21120 ft/hr * 1hr/60 min = 352 ft/ min
multiply by 40 minutes
352 ft/min * 40 min =14080 ft
-8
On the number line if you are at positive 8 and add -8 you will lose 8 and get zero! Hope this helps!
