Respuesta :
there is no question here, so I'll break down a few things. Electricity- 35% (.35) of the displays is 42. Renewable energy- 2/5 or .4 of the displays is 48 displays. The rest of the displays (100-35-40, or 25%) on gas are 30.
Answer:
There were 30 displays about the uses of gas.
Step-by-step explanation:
We are given the following information:
Total number of displays = 120
Displays about electricity = 35%
[tex]35\%\times 120 = \displaystyle\frac{35}{100}\times 120 = 42[/tex]
Displays about renewable energy =
[tex]\displaystyle\frac{2}{5}\times \text{Total number of displays} = \frac{2}{5}\times 120 = 48[/tex]
Display about uses of gas =
[tex]\text{Total number of displays - Displays about electricity - Displays about renewable energy}\\= 120 - 42 -48\\=30[/tex]
There were 30 displays about the uses of gas.
