Answer:
Step-by-step explanation:
1. Area of a parallelogram = base * height
area = 10 * 4 = 40 in squared
perimeter = 2(a + b)
perimeter = 2 * (5 + 10) = 2 * 15 = 30in
2. Area of triangle = 1/2 * base * height
area = 1/2 * 21 * 8 = 84 cm squared
perimeter = sum of outer perimeters
perimeter= 10cm + 17cm + 21cm = 48cm
3. area of trapezium = 1/2 * (a+b) * h
area = 1/2 * (6+12) * 4 = 36ft squared
perimeter = sum of outer perimeters
perimeter = 5ft + 6ft + 12ft + 5ft = 28ft
Answer:
1015 widgets
Step-by-step explanation:
First investigate how many widgets can machine A produce in 1 hour:
If it produces 435 in 3 hours, then it will produce one third of that in one hour:
In ONE (1) hour
widgets
Therefore in seven (7) hours it will produce seven times the amount it does in one hour, that is:
widgets
See attached graph: v is on the y-axis and t is on the x-axis
Answer:
Shift 6 units right.
Step-by-step explanation:
Easiest way to answer this question is to plot the two graphs:
Let's plot these graphs and analyse each graph.
Lets take the graph of
that is attached.
We can clearly see that graph intersects x axis at x=0 and then essentially looks like y=x is mirrored by the y axis.
Now when we look at the
that is attached,
We can see that graph intersects x axis at x=6 and is a composite graph of
and its mirrored graph by y=6.
We can clearly see that graph has moved 6 units to the right.
Answer: 11 pounds
Step-by-step explanation:
x : # of pounds an electronic is
9.98 + 0.75x : total cost of shipping an electronic that is "x" pounds
9.98 + 0.75x = 18.23
0.75x = 8.25
x = 11 pounds
