Answer:

£9

Step-by-step explanation:

£3   ->   €4

            x3

£?    ->  €12

so three times three

3 x 3 = 9  

Another way

3 divided by 4 is .75

so multiply .75 by 12

Check the picture below.

the radius, so-called because if we circumscribe the triangle in a circle, that'd be the radius of the circumcircle, is 3 inches, as you see there in the picture in red.

now, bear in mind that the triangle is an equilateral one, and therefore, 180/3 = 60, meaning all its interior angles are congruently 60°.

if we run the radius of the triangle, like there, it will cut one of those interior angles in half, namely the radius is an angle bisector, and if we run a perpendicular line to the bottom side, like the dashed one there, we end up with a 30-60-90 triangle, to which we can apply the 30-60-90 rule, as you see it there.

since we know what half of a side of the triangle is, as you see it there in blue, then we can use that and plug it in at

\bf \textit{area of an equilateral triangle}\\\\
A=\cfrac{s^2\sqrt{3}}{4}~~
\begin{cases}
s=length~of\\
\qquad a~side\\
-------\\
s=\stackrel{\frac{3\sqrt{3}}{2}+\frac{3\sqrt{3}}{2}}{3\sqrt{3}}
\end{cases}\implies A=\cfrac{(3\sqrt{3})^2\sqrt{3}}{4}
\\\\\\
A=\cfrac{(3^2\sqrt{3^2})\sqrt{3}}{4}\implies A=\cfrac{(9\cdot 3)\sqrt{3}}{4}\implies A=\cfrac{27\sqrt{3}}{4}

The North Colony Trail at Royal Gorge, Colorado, is 18 miles long. Stacey has hiked eight miles to a resting spot. She hikes the
Kruka [31]

Answer:

4 h

Step-by-step explanation:

The resting spot was at the 8 mi mark.

When Stacey reached the 16th mile, they had covered  

16 mi - 8 mi = 8 mi

They took 2 h for every 1 h, so

\text{Time required} = \text{8 mi} \times \dfrac{\text{1 h}}{\text{2 mi}} = \textbf{4h}

It may be easier to do this calculation on a number line. Each jump of 2 mi represents 1 h, and there are four jumps, so they took four hours.

A whole number is 6 more than 2 times another number. The sum of the two numbers is less than 50. This can be written in an ineq
balandron [24]

The smaller number, x from the inequality x + 2x + 6 < 50 is x < 14.67

<h3>Inequality</h3>

x + 2x + 6 < 50

3x + 6 < 50

  • collect like terms

3x < 50 - 6

3x < 44

  • divide both sides by 3

x < 44/3

x < 14.6666666666666

Approximately,

x < 14.67

Therefore, the smaller number, x is approximately x < 14.67
