Answer:
The answer to your question is below
Step-by-step explanation:
Process
1.- Transform the inequality to a line
2x - y < 4
2x - y = 4
2.- Find the x and y-intercepts
If x = 0, 2(0) - y = 4
0 - y = 4
y = -4 (0, -4)
If y = 0 2x - 0 = 4
2x = 4
x = 2 (2, 0)
3.- Do not consider graphs 1 and 2 because do not go through (0, -4).
4.- The answer is graph three because of the inequality "<", we look for the shaded region below the line.
Answer:
27in
Step-by-step explanation:
1ft=12in
(12*2)+3=27in
Answer:
54 degrees
Step-by-step explanation:
This is trigonometry. So we are given the adjacent leg and hypotenuse. So we can use cosine(cah from soh cah toa)
We will have to use the inverse of the trig ratios.
Remember!
cos^-1 is not 1/cos(that is sec)
cos^-1(27/46)
acos(27/46)
54.0586701 and so on
Round to nearest degree 54
Ok, so 11:9
11-9 = 2
which means that 124= 2:1
124/2 = 62
so 62:0
now 11 x 62= 682
9 x 62= 558
so the ratio is 682:558
now 682 + 558 = 1,240
There are 1,240 total students in the school. 682 boys and 558 girls
