Answer:
Perimeter of MNO = 38.71 in.
Area of MNO = 63.73 sq. in.
Step-by-step explanation:
Since the two triangles are similar, this means that
- linear dimensions are proportional to ratio of corresponding sides
- areas are proportional to ratio of corresponding sides.
Ratio of corresponding sides of MNO to DEF
= 6.7/9
Therefore
Perimeter of MNO = P*6.7/9 = 38.71 in.
Area of MNO = A*(6.7/9)^2 = 63.73 sq. in.
all results have been calculated to the second place of decimal
Answer:
a) 
b) 
c) 
Step-by-step explanation:
a) The slope / gradient is the coefficient of
, so for a) it will be
.
C is the y-intercept, so the full equation will be
.
b) Again, since the slope is 6, we know the coefficient of
will be 6.
Now, we have a point on the line and so far, we know the equation is
. The coordinates of the point are (2,-6). So now we substitute the y and x values into the equation in order to find C.




c) To find the gradient we must use the formula
.
rise = change in y value
run = change in x value
so, the gradient 
Now the equation is 
Again, to find C we substitute any of the coordinates into the equation. I will use (-1,3).



so c) is 
Answer:
B
Step-by-step explanation:
Answer:
5 weeks
Step-by-step explanation:
319.50-21.95=297.55
297.55/63.00=4.72
Since he can't wait for those many weeks, you would round it to 5 so he has enough money
Answer: 
Step-by-step explanation:
You need to convert from mixed number to decimal number.
In order to do this, you can follow the steps shown below:
1. You must divide the numerator of the fraction by the denominator of the fraction.
2. Now you must add the quotient obtained to the Whole number part.
Then, you get:

Then, the scale image that maps "Figure A" onto "Figure B" is:

Finally, in order to find the value of "x", you need to multiply the given length of the corresponding side of "Figure A" by
.
Therefore, the result is:
