Answer:
7.5'
Step-by-step explanation:
Use trigonometry.
Draw it out.
the hypotenuse is 15.
You want to find the adjacent side.
Use cosine (the adjacent over hypotenuse)
cos60=A/15
15cos60=A
7.5=A
Answer: ~73.89% of students at school are not freshmen
Step-by-step explanation:
To find a percentage, you need to divide the partial group by the large group. For example, if I have 2 bananas, and 10 fruits, what percentage of bananas do I have? The correct answer would be (2 bananas ÷ 10 fruits), which equals 20% (the equation equals 1/5, or 0.2, but when finding percentages, you multiply the final answer by 100 and add the % sign.).
Now, you have 223 freshmen and 854 students. To calculate the percentage of students at the school other than freshman, you need to find out how many students aren't freshman. Do this by finding the difference of the amount of students in the school and the amount of freshmen.
> 854 - 223 = 631 students that are not freshmen
Use this number to find out the percentage of students that are not freshmen.
> 631 non-freshmen ÷ 854 total students ≈ 73.89%
(2,3) and (-1,-5)
Distance =√(-1-2)^2 +(-5-3)^2
Distance =√73 (diamter)
radius = (√73) / 2
area of semi-circle:
= 1/2 πr^2
= 1/2 π ((√73) / 2)^2
= 73 π / 8
= 9.125 π
area of triangle:
= 1/2 (8)(3)
= 12
Area of the figure = area of semi-circle + area of triangle<span>
</span>= 9.125π + 12
answer
9.125π + 12
Answer:
A: If Z is the centroid, it means that it is the median to all segments it is on.
B: CN = 5.5 , we know that the given long end of a segment is 2 times the size of a whole (which , in total, is divided into 3 parts).
AZ = 9, since its a long side, 4.5 is half of that given line (AZ). Which means that the continuation of that whole line AN, which is ZN, is also 4.5. Hence, CB = 4.5•3= (13.5)
Step-by-step explanation:
Add up the legnths of the cable then multiply by 1.5
35+50=85
85 times 1.5=127.5
the answer is $127.50
