Number of Gallons 2 4 x
Travka [436]

Answer:

The value of x is 8 gallon.

Step-by-step explanation:

Given a table  showing approximate conversion from gallons to liters.

Number of Gallons    2      4      x

Number of Liters      7.6  15.2  30.4

We are required to find value of x,

Given : 2 gallon is equal to 7.6 liters.

⇒  1 liter is equal to \frac{2}{7.6}=0.263 liters. ........(1)

given, x gallon equal to 30.4 liters.

⇒ 1 liter is equal to \frac{x}{30.4} liters.  .........(2)

from (1) and (2),

⇒  0.263=\frac{x}{30.4}

Solving for x, we get,

⇒  0.263 \times 30.4=x

⇒  7.9952=x

Approximately x = 8

Thus, the value of x is 8 gallon.

Which is true about the slope of a line?
Inessa05 [86]

Answer:

Step-by-step explanation:

The slope of all lines in quadrant 1 is positive. FALSE

The slope of a line does not depend on the quadrant.

The slope of <u>all lines</u> that pass through the origin is undefined.FALSE

The slope of some lines that pass trough the origin are undefined ( lines that are vertical have undefined slope)

The larger the slope, the longer the line.FALSE

The lines do not get longer or shorter because they go to infinity in both directions.

The larger the magnitude of the slope value, the steeper the line. TRUE

The larger the absolute value of the slope the steeper the slope.

Need help with this one also
andriy [413]

Answer:

scale factor 3 is the answer.

Step-by-step explanation:

Length = 18 in

Breadth = 3 in

height = 10 in

Volume of cuboid = l × b × h

V = 18 × 3 × 10

V = 540 in³

540 in³ is the original volume. The volume needs to be tripled, so multiply the original volume with 3

V = 540 × 3 = 1620 in³

∴ 1620 in³ will be the new volume if it's tripled and the scale factor is 3.

A line passes through (9, –9) and (10, –5).Write an equation for the line in point-slope form.
CaHeK987 [17]
Y - y1 = [-9-(-5)]/[(9-10] * (x - x1)

y - (-9) = [-9 + 5] / [-1] * (x - 9)

y + 9 = (-4) / (-1) * (x - 9)

y + 9 = 4(x - 9)

y + 9 = 4x - 36

y = 4x - 36 - 9

y = 4x - 45  This is the slope - intercept form.

y - 4x + 45 = 0 This is the standard form
