Answer: Radius
Step-by-step explanation: The radius of a circle is a segment that joins the center of the circle to a point on the circle.
The minute hand on a clock would start in the center and go outwards towards a certain number. However, the minute hand would not go the full length across the clock so it's not the diameter.
The circumference of a circle which is another way of saying the perimeter of the circle is the distance around the circle so it would not be the circumference.
This means that the minute hand would represent the radius of a clock.
15 + 55 + 40 + 39 + 68 = 217
Perfect squares between 260 and 320...
17 is the perfect square of 289 which is between 260 and 320
289 - 217 = 72
72 is the missing number.
It doesn't matter. It can't be correct either way.
The range says that 'x' is a number between 90 and 180.
Neither -0.6 nor +0.6 is between 90 and 180.
Looking at the question, I'm assuming it has a mistake.
However, I will first attempt to solve it normally:
Simply combine like terms to get 5x = 180, and thus x = 36, and y = 72
The first mistake possibility is that the first equation should be <u>3x + 2y = 180</u>
If that is the case, simply substitute in 2x for y, turning the equation into
3x + 2 (2x) = 180
3x + 4x = 180
7x = 180
Thus, x = 25.715 and y = 51.43
Another possible mistake is that the first equation should be <u>3y + 2x</u><u> </u><u>= 180</u>
Solve similar to the first mistake
3 (2x) + 2x = 180
6x + 2x = 180
8x = 180
Thus, x = 22.5, and y = 45
Hope it helps :)
Amount of green grapes bought =
pounds
Amount of red grapes =
pounds
Let us assume that both the grapes have same price per pound.
Total quantity of grapes = 
=
= 3.7 pounds
Price of 1 pound of grapes = $2.99
So price of 3.7 pounds =
=11.063
Price is $11.063
Hence, Lexi spent less than $12.
