Answer:
Yes, because the bike order meets the restrictions of 4c + 6a ≤ 120 and 4c + 4a ≤ 100
Step-by-step explanation:
4c + 6a ≤ 120:
You can set up the inequality 4c + 6a ≤ 120, because it takes 4 hours to build per child bike (c) and 6 hours to build an adult bike (a), all together this time cannot surpass 120 hours. That is why you use the 'less than or equal to' sign.
4c + 4a ≤ 100:
You can then set up the inequality 4c + 4a ≤ 100, because it takes 4 hours to test a child bike (c) and 4 hours to test an adult bike (a). Since 100 hours is the max amount of time they can use to test out bikes, you will use the 'less than or equal to' sign.
4(5) + 6(15) = 20 + 90 = 110. 110 is less than 120
4(5) + 4(15) = 20 + 60 = 80. 80 is less than 100
Yes, because the bike order meets the restrictions of 4c + 6a ≤ 120 and 4c + 4a ≤ 100
Answer:
you should know this. you tell me how many?
Using trigonometric relations, we will see that for the given right triangle:
sin(x°) = 3/5
cos(y°) = 3/5
<h3>
How to find the wanted values?</h3>
Remember that for a right triangle for any of the internal angles that are not 90°.
sin(a) = (opposite cathetus)/(hypotenuse)
cos(a) = (adjacent cathetus)/(hypotenuse).
In this case, the two cathetus measure 4 units and 3 units, so the hypotenuse measures:

Then for x°, the opposite cathetus measures 3 units, then we have:
sin(x°) = 3/5
And for y°, the adjacent cathetus also measures 3 units, so:
cos(y°) = 3/5
These are equal because both depend on the same cathetus of the right triangle.
