Answer:
Step-by-step explanation:
There are 950 students at Hanover High School. The ratio of the number of freshmen to all students is 3:10. This means that the number of freshmen is 3/10 × total number of students.
Number of freshmen = 3/10×950 =285 freshmen
The ratio of the number of sophomore to all students is 1:2. This means that the number of sophomore is 1/2 × total number of students.
Number of sophomore = 1/2×950 =475 sophomore
The ratio of the number of freshmen to sophomore is the number of freshmen/ the number of
sophomore.
It becomes 285/475 = 57/95
Answer with Step-by-step explanation:
We have to prove that
by using Euler's formula
Euler's formula :
By using Euler's identity, we get
Comparing imaginary part on both sides
Then, we get
Hence, proved.
Answer:
(0,-7)
Step-by-step explanation:
If nay point is form (x,y)
x is abscissa can be also called x axis coordinate
y is ordinate can be also called y axis coordinate
ordiantes are points lying on y axis.
For any point lying on y axis, its x-axis coordinate will be 0
given that ordinate is -7. it means that value of y coordinate is -7
Thus, coordinates of the point is (0,-7)
Answer: 18
Step-by-step explanation: well 9 x 12 = 108 then divide it by 6 and yyou get 18 wich is 6 x 3
Add 145, 156, 210. and 255 then divide by 4. The mean equals 184.
