In London today, four times the high temperature was more than twice the high temperature plus

4vir4ik [10]

Answer:

Let's define the high temperature as T.

We know that:

"four times T, was more than 2*T plus 66°C"

(i assume that the temperature is in °C)

We can write this inequality as:

4*T > 2*T + 66°C

Now we just need to solve this for T.

subtracting 2*T in both sides, we get:

4*T - 2*T > 2*T + 66°C - 2*T

2*T > 66°C

Now we can divide both sides by 2:

2*T/2 > 66°C/2

T > 33°C

So T was larger than 33°C

Notice that T = 33°C is not a solution of the inequality, then we should use the symbol ( for the set notation.

Then the range of possible temperatures is:

(33°C, ...)

Where we do not have an upper limit, so we could write this as:

(33°C, ∞°C)

(ignoring the fact that ∞°C is something impossible because it means infinite energy, but for the given problem it works)

Who can help with geometry

Kay [80]

Answer:

h = 21.5cm.

Step-by-step explanation:

Step one: Simplify the volume.

220.16 x (pi) = 691.65cm^3.

Step two: Isolate h.

Cylinder volume equation: V = (pi)(r^2)(h), where r is the radius and h is the height.

Divide out the pi and r^2 on both sides to isolate h and move the equation to V/(pi)(r^2) = h.

Step three: Solve for h.

691.65/(pi)(3.2^2) = 21.5cm rounded to the nearest tenths place.

To illustrate this, please check the diagram below.

Solve the equation 18x - 9 = 5+ 12x

Hitman42 [59]

Answer:

$x = 2\frac{1}{3}$

Step-by-step explanation:

Try to get x alone on one side

Add nine to both sides

18x - 9 = 5 + 12x

+ 9 + 9

Subtract 12x from both sides

18x = 14 + 12x

-12x -12x

Now that you have x alone on one side divide both sides by 6

6x = 14

$\frac{6x}{6} = \frac{14}{6}$

$x = 2 \frac{2}{6} or 2 \frac{1}{3}$
