If the ratio of girls to boys in a class is 3:5, the fraction of the class that are girls is...
Hope this helps!!
CT=90°
BTA=90°
x=29
CT=37
TA=20
CA=57
Step-by-step explanation:
they say BT is an altitude ( or height) . Altitudes are perpendicular meaning that:
BTC =90°
BTA=90°
Therefore:
(3x+3)°=90°
3x=90-3
3x=87°
x=29
CT:
x+8
=29+8
=37
TA:
x-9
=29-9
=20
CA:
=CT+TA
=37+20
=57
20.4 is greater than 0.75
Answer:
Option D
0.6
Step-by-step explanation:
Given that there are 5 colour marbles in a large bag.
The colours are red, orange, yellow, blue and green.
Also given that there are equal amounts of each colour
Let n be the no of marbles of each colour.
Then total no of marbles = 5(n) = 5n
No of red,blue and yellow marbles = n+n+n = 3n
Prob of drawing a red or blue or yellow = P(red)+P(blue)+P(yellow)
=
= 0.60
The answer is C. No, the adjacent sides are not perpendicular. (Apex)
