In a store, 9/200 of the shirts are pink and 69/600 are orange. What percent of the shirts are not pink or orange?​
pychu [463]

Answer:

84%

Step-by-step explanation:

The percentage of pink shirts

= 9/200 × 100%

= 9/2

= 4.5%

The percentage of orange shirts

= 69/600 × 100%

= 69/6

= 11.5%

The percentage of the shirts which are not pink or orange

= 1 - 4.5% - 11.5%

= 84%

<u>Alternative</u>

Find their common denominator.

9/200

= 9×3 / 200×3

= 27/600

The total percentage of shirts in pink and orange

= (27/600 + 69/600) × 100%

= 96/600 × 100%

= 16%

The percentage of the shirts which are not pink or orange

= 1 - 16%

= 84%

Which graph shows a set of ordered pairs that represent a function?<br><br>Need help​
Sveta_85 [38]

Answer:

The third graph, the top right graph

Step-by-step explanation:

A function when determined graphically is a graph that passes the straight line test, which means if there is any two points on the graph which you can plot a vertical straight line going through both of them it is not a function.  If 1 x value is equal to 2 y values, it is not a function.

I need step by step please 3(x-2)^2+1=13
Romashka-Z-Leto [24]

Answer:

x_{1} = 0. \:  \:  \:  x_{2} = 4

Step-by-step explanation:

3(x - 2)^{2}  + 1 = 3

3( {x}^{2}  - 4x + 4) + 1 = 13

{3x}^{2}  - 12x + 12 + 1 = 13

{3x}^{2}  - 12x + 13 = 13

{3x}^{2}  - 12x = 0

x \times (x - 4) = 0

x = 0

x - 4 = 0

\boxed{\green{x_{1} = 0. \:  \:  \:  x_{2} = 4}}
