Answer:
The number of calories is going to be pretty close to proportional to the area of the pizza. Figure out the area of a 6-ince pizza, and then figure out the area of a 14-inch pizza. Then you're going to get a proportion:
(Area of 14 inch pizza) is to (Area of 6 inch pizza) as (Number of calories in 14 inch pizza) is to (Number of calories in 6 inch pizza.
You know the areas of both sizes and the number of calories in the 6 inch pizza, so you should be able to find the number of calories in the 14 inch pizza.
Then divide by 8 to get the number of calories in each slice.
Length(l)= 2w
width(w)= w
Perimeter(P)= 2w+2l= 72 (simplify expression: divide each side by 2 )
P= w+l= 36 (plug in "2w" for "l")
P= w+(2w)= 36
P= 3w= 36 (divide each side by 3 to find the width)
w= 12 units
find length:
l=2w
l= 2(12)
l= 24 units
Answer:
The length of this rectangle is 24 units and the width is 12 units.

i just know its right
Answer:
Same sides
Step-by-step explanation:
When the sides are the same then the triangles are congruent. because they all have exactly the same sides. because the two triangles do not have exactly the same sides.
Answer:
Mean = 1.5
Standard Deviation = 1.206
Step-by-step explanation:
Percentage of Siberian Huskies with two different colored eyes = p = 3% = 0.03
Sample size selected = n = 50
We have to find the mean and standard deviation of the number of puppies with two different colored eyes.
Either the puppies will have two different colored eyes or they won't. Sample size is fixed in this case which is 50. A puppy with two colored eyes is independent of other puppies, this means the trials are independent. The probability of success is fixed in this case which is 3%. This setting satisfies all 4 conditions of a Binomial experiment, so we will use the formula relevant to Binomial experiment to answer this question.
Mean number = 
Using the values, we get:
Standard deviation of Binomial experiment is calculated as:
Using the values, we get:
