Answer:
Perimeter is 80cm
Step-by-step explanation:
A rectangle's area is calculated by multiplying the length by the width. If we are given the area of the rectangle and the length then we would simply need to solve for the width of the rectangle using the area formula we just mentioned...
A = l * w
336 = 12cm * w ... divide both sides by 12cm
28cm = w
Now we can see that the width of this rectangle is 28cm. To find the perimeter we need to add all four sides together, since we know that a rectangle's opposite sides are the same then we add the length and the width twice to calculate the perimeter (P)
P = 12cm + 12cm + 28cm + 28cm
P = 80cm
The scale factor from Figure A to Figure B is 1/2
<h3>What is the scale factor from Figure A to Figure B?</h3>
The given parameter is the figure.
On the figure, we have the following corresponding sides
Figure A = 6
Figure B = 3
The scale factor from Figure A to Figure B is calculated as:
Scale factor = Figure B/Figure A
So, we have:
Scale factor = 3/6
Evaluate
Scale factor = 1/2
Hence, the scale factor from Figure A to Figure B is 1/2

#SPJ1
Yes, she eventually stops talking; either due to hoarseness, fatigue or death.
The answer will be 31 degrees
1. first we find how many defective capacitors are there out of 133, 450:
in 34 capacitors --------- 1 defective
in 133,450 capacitors --------- x defective
so
is the expected number of defective capacitors.
2.
So there are in total 133,450-3925=129,525 working capacitors.
3.
To assemble 1,987 smartphones the corporation needs 1,987*66= 131,142 working capacitors.
4.
The number of required capacitors is larger than the number of the available ones, so 133,450 capacitors are not enough.
