A cube has 6 congruent square faces

The area of 1 face = \frac{2}{3} × \frac{2}{3} = \frac{4}{9}

Multiply by 6 to obtain surface area of cube

In ∆DFG, m∠D = 78o and m∠F = 32o. Which lists the sides in order from longest to shortest?
ioda

Answer:

Side FG, Side DF, Side DG

Step-by-step explanation:

The angles of a triangle add up to 180° and since we know 2 of the angles add up to 110° the missing ∠G can be found by subtracting

180°-110°=70°

The opposite side of the largest angle is the largest side. The opposite is also true.

Since the angle from greatest to least is ∠D, ∠G, ∠F then the sides from greatest to least is Side FG, Side DF, Side DG

Solve for m.<br><br> -5m = -35<br> m = <br> please exsplain your answer theroly
andrew-mc [135]
Simple,

so you have...

-5m=-35

You are trying to find m, so, to isolate the variable divide both sides by -5:

\frac{-5m}{-5} = \frac{-35}{-5}

m=7

Now, to check your work, plug in m.

-5(7)=-35

-35=-35

Thus, you know your answer is correct.

Alina [70]

Answer:

<h2> Amount in liters is 47.9 liters</h2>

Step-by-step explanation:

The Question is incomplete, it does not provide the measurements or options to choose from, but we can estimate the answer

Step one:

Given data

Taryn Bought 12.6gallons of gasoline

1 gallon of gasoline is  3.8 liters

We want to convert from gallons to liters

Step two:

----if 1 gallon has 3.8 liters

then 12.6 gallons will have x liters

cross multiply we have

x= 12.6*3.8

x=47.88 liters

Hence the estimated amount in liters is 47.9 liters
