Answer:
23) option c
JL ≈ 9.3
25) option c
y ≈ 9.6
Step-by-step explanation:
<h3>25)</h3>
Given in the question that,
cos(21°) = 9 / y
y = 9/cos(21°)
y = 9.64
y ≈ 9.6(nearest tenth)
<h3>23)</h3>
Given in the question that the hypotenuse of right angle triangle = 12
To find,
height of the right angle triangle
angle k = 39°
so by using trigonometry identity
cos(39) = opp/hypo
cos(39) = JL / KL
JL = cos(39)(12)
JL = 9.32
JL ≈ 9.3

Mr. Patel used 4.5 bags of seed
<em><u>Solution:</u></em>
Given that,
Over the summer, Mr. Patel refilled a bird feeder 24 times using 6 cups of seed each time
A bag of seeds holds 32 cups
1 bag of seed = 32 cups
Given that Patel refilled 24 times using 6 cups of seed each time
<em><u>Then, the number of cups used for the 24 times is given as:</u></em>

<em><u>Now we have to find the bags of seed needed for 144 cups</u></em>
Let "x" be the number of bags of seed for 144 cups
From given,
1 bag of seed = 32 cups
"x" bags of seed = 144 cups
This forms a proportion and we can solve it by cross multiplying

Thus 4.5 bags of seed is used by Mr.patel
