You take 298 x .15 =44.7
298-44.7=253.3
Given width is 24 less than length.
W=L-24
Perimeter = 2(W+L)=2(L-24+L)=4L-48
But we're also given perimeter = 172'
Therefore 4L-48=172
solve for L
4L=172+48=220
L=55'
W=55-24 = 31'
Check: Perimeter = 2(W+L)=2(31+55)=2*86=172' good!
Answer: The dimensions of the garden are 31' * 55'
Answer:

Step-by-step explanation:
1/1140 because the 3 students make one group of 1140 possible
Answer:
Ans: 0.766
Step-by-step explanation:
Use the trig identity: cos (a + b) = cos a,cos b - sin a.sin b
cos (25 + 15) = cos (40) = cos 25.cos 15 - sin 25.sin 15.
The arc
40
∘
doesn't have exact functional value.
You may get its approx. value by calculator.
cos 40 = 0,766
