Answer:
The scale factor is equal to 1/2
The dimensions of each channel when splits the screen is 46 in x 38 in
Step-by-step explanation:
we know that
The dimensions of the new television is 92 in x 76 in
Remember that
If two figures are similar, then the ratio of its areas is equal to the scale factor squared
Let
A1 -----> the area of the new television
A2 ----> the area of each channel when splits the screen
z-----> the scale factor

we have that
The area of the new television is 4 times the area of each channel



-----> the scale factor
so
When splits the screen, the dimension of each channel is equal to
92/2 in x 76/2 in
so
46 in x 38 in
Remember, if two figures are similar then the scale factor is equal to the ratio of their corresponding sides
<em>Verify the value of the scale factor</em>
92/46=1/2
or
76/38=1/2
Answer:
1000
Step-by-step explanation:
Doing this on a calculator yields 1000.
Alternatively, do part or all of the problem in your head:
Rewrite 42 ÷____= 0.042 as
42
------------
0.042
and move the decimal points 3 place to the right:
42 becomes 42000, and 0.042 becomes 42. Thus, we have:
42000
------------ = 1000
42
Answer:
This is a linear graph.
Step-by-step explanation:
Since the x values increase at a constant of 1. The y-values have a 1st difference of -4 which means the graph is linear.
Answer:
156
Step-by-step explanation:
6×12=72
7×12=84
72+84=156
Answer:
3.143
Step-by-step explanation:
Since you're rounded it to the third decimal, you look at the fourth one. And since the fourth one is 8, ur going round 2, which is the third decimal to 3.
