Dana painted a wall in her bedroom that is 10.5 feet tall and 23.5 feet wide.she used exactly 3quarts of paint to cover the wall

Scrat [10]

82.25 square feet

Start off by multiplying 10.5 by 23.5, to get the area of her wall - 246.75 square feet. This took up 3 quartz of paint, so divide both 246.75 by 3 to find out how many square feet were painted with only 1 quartz, 82.25 square feet! :D Hope I helped!

What symbol makes this comparison true? 200 mL O 2 L <>

vova2212 [387]

Answer:

For the first case converting ml to L we got:

$200mL *\frac{1L}{1000 mL}= 0.2 L$

And we see that 0.2 L is lower than 2 L so then:

$200 mL < 2L$

And in the other way if we convert L to mL we got:

$2L *\frac{1000mL}{1L} = 2000 mL$

And we see that [/tex] 200mL < 2000 mL[/tex]

So then the answer would be <

Step-by-step explanation:

For this case we can solve this problem converting ml to L or converting L to ml.

For the first case converting ml to L we got:

$200mL *\frac{1L}{1000 mL}= 0.2 L$

And we see that 0.2 L is lower than 2 L so then:

$200 mL < 2L$

And in the other way if we convert L to mL we got:

$2L *\frac{1000mL}{1L} = 2000 mL$

And we see that [/tex] 200mL < 2000 mL[/tex]

So then the answer would be <

Answer:

f(-10) = 186

Step-by-step explanation:

Sub in -10 to the x - values:

f(x) = 2 $x^{2}$ + $x$ - 4

f(-10) = 2(-10)^2 - 10 - 4

f(-10) = 200 - 10 - 4

f(-10) = 186
