Answer:
Step-by-step explanation:
The diagram of the triangles are shown in the attached photo.
1) Looking at ∆AOL, to determine AL, we would apply the sine rule
a/SinA = b/SinB = c/SinC
21/Sin25 = AL/Sin 105
21Sin105 = ALSin25
21 × 0.9659 = 0.4226AL
AL = 20.2839/0.4226
AL = 50
Looking at ∆KAL,
AL/Sin55 = KL/Sin100
50/0.8192 = KL/0.9848
50 × 0.9848 = KL × 0.8192
KL = 49.24/0.8192
KL = 60
AK/Sin25 = AL/Sin 55
AKSin55 = ALSin25
AK × 0.8192 = 0.4226 × 50
AK = 21.13/0.8192
AK = 25.8
2) looking at ∆AOC,
Sin 18 = AD/AC = 18/AC
AC = 18/Sin18 = 18/0.3090
AC = 58.25
Sin 85 = AD/AB = 18/AB
AB = 18/Sin85 = 18/0.9962
AB = 18.1
To determine BC, we would apply Sine rule.
BC/Sin77 = 58.25/Sin85
BCSin85 = 58.25Sin77
BC = 58.25Sin77/Sin85
BC = 58.25 × 0.9744/0.9962
BC = 56.98
All the equations can be graphed and solved by graphing. They can also be solved using various other methods
Answer:
<h2>$13.30</h2>
Step-by-step explanation:
Step one:
given
We are told that 3 apples seels for $5
let us first find the selling price of 1 apple
an apple = 5/3
=$1.6
Required
Step two:
The selling price of 8 apples
if 1 apple sells for $1.6
then 8 apples will sell for
=8*1.6
=$13.30
Answer:
a) = 0.9739
b) = 0.969
c) option A is correct
Step-by-step explanation:
Given that:
sample size n = 30
SST = 1803
SSR = 1756
The adjusted 
is computed as:
where;
From the values in the table, we can multiply the speed by the time to find out the amount of miles she travels a day. This is shown below:
30 mph * 2.5 hours = 75 miles
40 mph * 1.875 hours = 75 miles
50 mph * 1.5 hours = 75 miles
60 mph * 1.25 hours = 75 miles
Therefore, she travels 75 miles to work. Given a speed of 24 mph, we divide 75 miles by 24 to find out how long it takes her to travel that far:
75 miles / 24 mph = 3.125 hours
