Answer:1.8701

Step-by-step explanation:

Area (A) of trapezium as marked is =\frac{1}{2}\left ( sum\ of\ parallel\ sides\right )\times height

A=\frac{1}{2}\left ( 3+6\right )\times 4

A=18in^2

Now for Volume we have to multiply by length because area is same across the length.

volume(v)=A\times length

Volume(v)=18\times 24

Volume(v)=432 in^3

Volume(v)=1.8701 gallon

Find the value of x so that L is parallel to M. State the converse used!
galben [10]

Answer:

<h3>6 degrees</h3>

Step-by-step explanation

Find the diagram attached. In Line geometry, there is a theorem that states that the sum of the adjacent interior angles is 180 degrees. According to the diagram, the adjacent interior angles are 7x- 15 and 24x + 9.

The sum of this angles must give 180 degrees as shown;

7x-15 + 24x + 9 = 180

7x+24x-15+9 = 180

31x-6 = 180

31x = 180+6

31x = 186

x = 186/31

x = 6

Hence the value of x is 6 degrees

One antifreeze solution is 20% alcohol. Another antifreeze solution is 12% alcohol. How many liters of each solution should be c
katrin [286]
Use this systems of equations to solve:

x = first antifreeze
y = second antifreeze

\left \{ {{.2x + .12y = .18(15)} \atop {x + y = 15}} \right.

Isolate y.

x + y = 15
Subtract x from both sides.
y = -x + 15

Substitute y into the other equation.

.2x + .12(-x + 15) = .18(15)
Simplify.
.2x - .12x + 1.8 = 2.7
Subtract 1.8 from both sides.
.08x = .9
Divide both sides by .08
x = 11.25

Substitute x in the equation that we isolated y in.

y = -11.25 + 15
y = 3.75

11.25 L of the first antifreeze and 3.75 L of the second.
