Answer:
Solution given:
model A printers [a] prints=80books per day
model B printers [b] prints=55books per day
total no of printers =9
no of model A printers be x
and
no of model B printers be [9-x]
According to the question;
ax+(9-x)b=670 books
substituting value of a and b; we get
80x+(9-x)55=670
80x-55x+495=670
25x=670-495=175
x=
=7
So;
no of model A printers =x=<u>7</u>
no of model B printers =9-x=9-7=<u>2</u>
<u>is</u><u> </u><u>your</u><u> </u><u>answer</u><u>.</u>
You need to use trigonometry
1. Tan37=x/2.1
1.58=x
Answer:
Exponents
Step-by-step explanation:
exponents are basic short cut to write numbers like 100, 1000, 10000, 1000000 and so on.
Exponents can also be defined as 10 raised to a power x whether positive or negative

They are mostly used in expressing units in standard form.
<h3>examples of basic positive exponents</h3>




basically the power represent the the number of zeroes after the 1.
<h3>examples of basic negative exponents</h3>




in negative exponents the power represents the number of zeroes before the 1. including the 0 behind the decimal point.
this is the basic lay down of how exponent work but one more quick example for maximum understanding
<h3>quick example</h3>




hope you grasp the concept involved in multiplication with other terms.
cheers
Not circle for sure. Line graph is for plotting not really demonstrating a change. Picto graph is just like line plotting. Probably the bar graph works the best to see the smoothness and flow of how it increases and decreases.
I think maybe c but I’m not sure!
