A) we know, circumference of circle = 2πr
i)Circumference of small pizza with radius of 8 inches; = 2*3.14*8 = 50.24 in.²
ii)Circumference of medium pizza with radius of 10 inches; = 2*3.14*10 = 62.8 in.²
iii)Circumference of large pizza with radius of 12 inches; = 2*3.14*12 = 75.36 in.²
b) we know, area of a circle = πr²
i)Area of small pizza with radius of 8 inches;= 3.14 * 8²= 200.96 in.²
ii)Area of medium pizza with radius of 10 inches = 3.14 * 10² = 314 in.²²
iii)Area of large pizza with radius of 12 inches; = 3.14*12² = 452.16 in.²
c) Joey should order pizzas of larger size 'cause he is very hungry & it will be most helpful for him 'cause of larger area.
Hope this helps!
Remember that when the exponents look like this (5^2)^-3, you multiply the exponents together
when it looks like this:
5^3 x 5^2 you add the exponents
so my example would equal 5^5
also remember that you can’t have negative exponents
To solve your problem:
1. multiply the exponents here: (5^2)^-3
2. add the exponents in the next step when you multiply by the 5^4
3. now, you should get a negative exponent on the top, and you already have one on the bottom. to get rid of these negative exponents, move the one in the denominator to the numerator and vice versa
so when you move the 5^-4 in the denominator to the numerator, it becomes 5^4
4. now, you simplify. you can either subtract the exponents and do it that way, or you can solve the exponents and then divide. either way will work, although the first is easier
Answer:
B. weight of a bag of apples
Step-by-step explanation:
A continuous random variable is a variable that is measured not counted. It can be any number between integers in decimal form.
So from the options given above, only the weight of bag of apples is a continuous variable as it will be measured.
While the others cannot be expressed in the form of decimals.
So the correct answer is:
B. weight of a bag of apples ..
To find the length of the diagonals, Troy should use the Pythagorean Theorem. The diagonal is going to be the hypotenuse of the triangle (the side directly across from the 90 degree angle).
a^2 + b^2 = c^2
6^2 + 10 ^2 = c^2
136 = c^2; find the square root of 136
c = 11.66 feet
Troy's diagonals are approximately 11.66 feet.
It is 230,000 because the first 9 gets rounded up because the next number is above 5
