Plssss hellpppppp meeeeeeeww
Step2247 [10]

Answer:

12

Step-by-step explanation:

When the numerators are the same, the denominator that is bigger has a lesser value. In this case, the inequality > shows that \frac{1}{10} is bigger than the fraction next to it so in order to find a fraction that is lesser in value than  \frac{1}{10}, we need to find a denominator that is <u>more than 10</u>, since 10 is the denominator of the first fraction. The only number more than 10 in the options is 12, so 12 is the answer.

Answer:

A. add the areas of both bases to the rectangular area around the cylinder.

Step-by-step explanation:

If we flatten out the cylinder we would have two circles and a rectangle. When you roll up the rectangle, it would make the body of the cylinder. Surface area by definition the total area the surface of an object occupies.

So to get it, we add up the different shapes that make up the cylinder, which is the two circles and the rolled up rectangle.

Stephen Curry's record during the 2017 - 2018 NBA final game is made up of 2-point shots and 3-points.
grandymaker [24]

Answer:

x =  12      ( two points shots )

y =  7       ( three points shots )

Step-by-step explanation:

Let´s call  "x" two points shots,  and  "y" three points shots, then

x  +  y  =  19

2*x  +  3*y  =  45

We have to solve a two-equation system for x and y

y =  19  - x

2*x  +  3 * ( 19 - x ) = 45

2*x  +  57  -  3*x   =  45

- x   =  45 - 57

-x   =  - 12

x  = 12

And     y  =  19  -  12

y  = 7
