Answer:
The approximate number of total students in the school is 650.
Step-by-step explanation:
Here, given the number of students with Mr. Shaffer has = 130 students
Let us assume the total number of students in the school = m
Now, given: 20 % of total students in the school = 130
⇒ 20 % of m = 130

or, m = 650
Hence the approximate total number of students in the school is 650.
34/4=8.5
8.5x5=42.5
The answer is $42.50
72 because 63 + 9 is basically 9×8
Answer:
Step-by-step explanation:
The layout looks like this.
r-----------s-----------------t
6.4
----------------9.3-----------
Now you want st so the formula is
rt = rs + st
9.3 = 6.4 + st Subtract 6.4 from both sides
9.3 - 6.4 = st Combine
st = 2.9
A dilation with scale factor 3 gives the effect of stretching the line AB three times longer, as shown in the diagram below
The slope will stay the same as dilation does not change the direction of the line
If point O lies on AB and is the center of dilation, then the point O must also lie on A'B'
Answer:
the slope of A'B' = 3
A'B' passes through point O
