Triangle J is shown below. James drew a scaled version of Triangle J using a scale factor of 4 and labeled it
2 answers:
Answer:
The area of triangle K is 16 times greater than the area of triangle J
Step-by-step explanation:
we know that
If Triangle K is a scaled version of Triangle J
then
Triangle K and Triangle J are similar
If two triangles are similar, then the ratio of its areas is equal to the scale factor squared
Let
z -----> the scale factor
Ak ------> the area of triangle K
Aj -----> the area of triangle J
so
we have
substitute
therefore
The area of triangle K is 16 times greater than the area of triangle J

Answer:
They will be at the same position after 2 hours.
Step-by-step explanation:
Here, it should be asked the time it will take for Anita to catch Brad.
Anita began riding at start of the path and is riding at rate of 18 mile per hour.
This means that, after t hours, her position will be given by:
Brad begin from a sport 10 mile ahead of her and I riding at rate of 13 mile per hour
This means that, after t hours, his position will be given by:
After how much time will they be at the same position?
This is t for which:
So
They will be at the same position after 2 hours.
Answer:
Step-by-step explanation:
Gavin made 6 out of 15 shots, so the probability that Gavin's next shot will be successful is
Jack made 7 out of 15 shots, so the probability that Jack's next shot will be successful is
The probability that they both make their next shot successfully is
For this case we must find an expression to find 40% of 25. So, we make a rule of three:
25 -----------> 100%
x -------------> 40%
Where "x" represents the amount that determines 40% of 25.
40% of 25 is 10. And an expression to find it is:
