Answer:
Part a) The ratio of the perimeters is
Part b) The ratio of the areas is
Step-by-step explanation:
Part A) What is the value of the ratio (new to original) of the perimeters?
we know that
If two figures are similar, then the ratio of its perimeters is equal to the scale factor
Let
z-----> the scale factor
x-----> the perimeter of the new triangle
y-----> the perimeter of the original triangle
we have
substitute
Part B) What is the value of the ratio (new to original) of the areas?
we know that
If two figures are similar, then the ratio of its areas is equal to the scale factor squared
Let
z-----> the scale factor
x-----> the area of the new triangle
y-----> the area of the original triangle
we have
substitute
The probability for rolling a sum of 7 is: 1/6
Step-by-step explanation:
Given that two six-sided dies are rolled the total outcomes will be:
n(S) = 36
Out of total outcomes we have to count the outcomes that sum up to 7
Let A be the event that the sum of outcomes is 7
Here the first number is the result of first die and second number is the result of 2nd die.
n(A) = 6
So the probability of A will be:
Hence,
The probability for rolling a sum of 7 is: 1/6

Answer:
6.25%
Step-by-step explanation:
Total = 1 ; as a decimal
1/2 = skittles
1/4 = M&Ms
Skittles +M&Ms = 1/2 + 1/4 = 3/4
Remainder = 1 -
Remainder =
Sour patch =
As a percentage , multiply 1/16 by 100 and it becomes 6.25%
