Answer:
BC ≈ 10.4 mm(1 decimal)
Step-by-step explanation:
The question forms a right angle triangle. The angle BAC = 90°. The side AB = 7.3 mm and the side CA = 7.4 mm. The length of BC can be solved below.
AC = opposite side = 7.4 mm
AB = adjacent side = 7.3 mm
BC = hypotenuse = ?
Using pythagoras theorem we can find the longest side which is the hypotenuse
c² = a² + b²(pythagoras formular)
where
c = hypotenuse side
BC² = 7.4² + 7.3²
BC² = 54.76 + 53.29
BC² = 108.05
square root both sides
BC = √108.05
BC = 10.3947101931
BC ≈ 10.4 mm(1 decimal place)

ok what teacher gave you this
Step-by-step explanation:
F = (-3,3)
scale factor of 10
-3 * 10 = -30
3 * 10 = 30
answer : (-30,30)
$33,075 = 0.05S + S
$33,075 = 1.05S
$33,075/1.05 = 1.05S/1.05
S= $31,500
Check
$31,500 * 5% = $1575 + $31,500 =$33,075
I think the way that you do is 5/5+3=5/8
5/8*4=2.5 so 2.5 is the answer
