Answer:
nice
Step-by-step explanation:
First, it would be helpful to find out how many teachers there are at the school.
2470 students x (1 teacher/26 students)=95 teachers
To find the number of teachers needed, just use the ideal ratio:
2470 students x (1 teacher/19 students)=130 teachers
So to reduce this ratio to 19:1, the school needs 130 teachers. To know how many new teachers the school needs, just subtract the ideal from the current amount.
130-95=35 new teachers needed
Answer:
Part A : About 5,931
Part B : 5,930.8
Part C : Yes, because it rounded it to the nearest full number
ANSWER
(–4.5, 4.25)
EXPLANATION
The first equation is
This function is in the slope-intercept form
The second equation is:
x + 2y = 4
2y =-x+ 4
The graph of the two functions are shown in the attachment.
The point of intersection represents the solution to the system of equations they represent.
The solution is
(–4.5, 4.25)
Answer:
67
Step-by-step explanation:
Complementary angles add to 90 degrees
<A + <B = 90
x+10 + 3x+28 = 90
Combine like terms
4x+38 =90
Subtract 38 from each side
4x+38-38 = 90-38
4x = 52
Divide by 4
4x/4 = 52/4
x = 13
We want to find <B
<B = 3x+28
= 3(13) +28
= 39+28
=67
