Answer:  \frac{2}{2},1\ \text{and}\ \frac{2}{2},1

Step-by-step explanation:

\Rightarrow \dfrac{2}{2}\ \text{is equivalent to 1}

\text{So, }\ \dfrac{2}{2},2\ \text{is equivalent to 1,2}

\text{Similarly, }\ \dfrac{2}{1},1\ \text{represents 2,1 or 1,2}

\text{So,}\ \frac{2}{2},1\ \text{and}\ \frac{2}{2},1\ \text{are represents same on number line.}

Help mee A scout troop are hiking in a forest. Starting from their base, they walk 4.2km south followed by 7.1km west. They want
slega [8]

Answer:

They should walk on a bearing of 59.4 degrees

Step-by-step explanation:

Given

South = 4.2km

West = 7.1km

Required

The bearing back to the base

The given question is illustrated with the attached image.

To do this, we simply calculate the measure of angle a using:

\tan(a) = \frac{Opposite}{Adjacent}

\tan(a) = \frac{7.1}{4,2}

\tan(a) = 1.6905

Take arctan of both sides

a = \tan^{-1}(1.6905)

a = 59.4^o

$\triangle abc$ and $\triangle dbc$ share $bc$. $ab = 5\ \text{cm}$, $ac = 12\ \text{cm}$, $dc = 8\ \text{cm}$, and $bd = 20\ \t
Ratling [72]
What terms govern the length of this side?The basic rule of the triangle.First side length must be less than the sum of the other two sides.So to find X we must take the largest side of the triangles and compare them with amounts from other sides.

5+x>12
8+x>20    and it's system

x>7
x>12
general solution is x>12
<span>The least possible integral is 13.

PS: It's may be </span>yet 12, but in this case, triangle  BCD become segment.

there are 3/4 as many boys as girls in a class of fifth-graders if there are 35 students in the class how many a
Arlecino [84]
Alright so turn 3/4 into a decimal.
3/4 =.75

We need to set up an equation. To do that are need to give boys and girls their own variables.

Girls= X

And since there is 3/4 as many boys
Boys=. 75X

Now we know the sum of boys and girls equals 35
X+.75X=35

X+.75X=1.75X
Now we have 1.75X=35

Divide by 1.75 and get
20=X

Now plug 20 into the equations got from before.
Boys =. 75*X = 20 *. 75 = 15
Girls = X =20

Your Answer:
15 boys
20 girls

You can check
20+15=35
15/20=3/4
