We know that
[surface area of a sphere]=4*pi*r²
r²=surface area/(4*pi)
r=√[surface area/(4*pi)]
surface area=450 in²
r=√[450/(4*pi)]------> r=5.98 in------------> r=6 in
the answer is
r=6 in
The expression can be used to determine the final cost of the cards will be 1.08 (0.87) y. Then the correct option is B.
<h3>What is the percentage?</h3>
The quantity of anything is stated as though it were a fraction of a hundred.
Jason purchased a pack of game cards that were on sale for 13% off.
The sales tax in his county is 8%.
Let y represent the original price of the cards.
Then the expression can be used to determine the final cost of the cards will be
⇒ y (1 - 0.13) (1 + 0.08)
⇒ y (0.87) (1.08)
⇒ 1.08 (0.87) y
Then the correct option is B.

Answer: By finding out what 2 numbers multiple together to get that answer
Step-by-step explanation:
like 20 times 20 is 400
so the square root is 20
Answer:
Mean= $ 1.96
Mode= No mode
Step-by-step explanation:
Mean is the value obtained by dividing the sum of all the observations by their numbers.
Mean is obtained by dividing the total number of the values with the number of values.
Mean= x1+ x2+ x3 + x4/ 4
Mean = $ 1.5 + $ 2.0 + $ 2.15 + $ 2.20/4= 7.85/4= 1.9625or 1.963 or $ 1.96
Mode is the most frequent occurring value in a data set. But since all the values in the given set occur only once the data does not have any mode .
There is no mode because every value has the same frequency, that is it occurs the same number of times.
Answer:
A shape can have more than one line of symmetry. Thus a rectangle has two lines of symmetry, an equilateral triangle has three lines of symmetry, and a square has four. A circle has an infinite number of lines of symmetry since it can be folded about any diameter.
