Second part :to find angle BAC keep the middle point of your protractor at point A.
Hope this helps u...!
Choice 'C' is the way to write that quantity.
-- 'b' and 'f' are two numbers.
-- Their sum is (b + f) .
-- Three times that sum is 3(b + f) .
Answer:
The one on the bottom right
Step-by-step explanation:
In order for something to be a function it has to pass the Vertical Line Test. To do this you draw an imaginary vertical line down your graph. If the graph touches the line more than one it is not a function. This rules out all others except the bottom right graph.
Answer:
There are 105 male fishes and 195 female fishes
Step-by-step explanation:
Let
x-----> the number of female fishes
y-----> the number of male fishes
we know that
65%=65/100=0.65
so
x=0.65(x+y) ----> equation A
x=2y-15 ----> equation B
substitute equation B in equation A and solve for xy
2y-15=0.65(2y-15+y)
2y-15=1.30y-9.75+0.65y
2y-15=1.95y-9.75
2y-1.95y=-9.75+15
0.05y=5.25
y=105 male fishes
Find the value of x
x=2(105)-15=195 female fishes
4x+10=86
(subtract 10 from both sides)
4x=76
(divide both sides by 4)
x=19
