Halmi had the most appropriate information because when you add both the girls and the boys up it is 56 after that you have to add 14+14=28.
28/56= exactly %50 of the entire group.
Answer:
s = 4
Step-by-step explanation:
3r = 10 + 5s
3×10 = 10 + 5s
5s = 30 - 10
5s = 20
s = 20 : 5
s = 4
A) by publishing articles in scientific journals-
because science progresses by them sharing their progress and results
Answer:
Sin of x does not change
Step-by-step explanation:
Whenever a triangle is dilated, the angle remains the same as well as the ratio for sides of triangle. For smshapes with dimensions, when shapes are dilated the dimensions has increment with common factor.
From trigonometry,
Sin(x)=opposite/hypotenose
Where x=4/5
Sin(4/5)= opposite/hypotenose
But we were given the scale factor of 2 which means the dilation is to two times big.
Then we have
Sin(x)=(2×opposite)/(2×hypotenose)
Then,if we divide by 2 the numerator and denominator we still have
Sin(x)=opposite/hypotenose
Which means the two in numerator and denominator is cancelled out.
Then we still have the same sin of x. as sin(4/5)
Hence,Sin of x does not change

General Circle function:
, where h is the x-coordinate of the center, k is the y-coordinate of the center, and r is the radius.
The radius of the circle is half the diameter so: 8 / 2 = 4
The x-coordinate of the circle is 5
The y-coordinate of the circle is -2
Plug in.
