Answer:

8 $\frac{3}{4} \\$

Step-by-step explanation:

Going from left to right on the number line we see that k is between 8 and 9. So 8 will be your whole number. The number line is divided into 8 sections between each whole number and k is located 6/8 between 8 and 9.

This mixed number is 8 6/8. We can reduce the 6/8 to 3/4 by dividing by 2 on the top and bottom. So your final answer is 8 3/4.

Answer:

8 and 3/4

Step-by-step explanation:

so there are 8 tic marks we know that there should be 10 so each tic mark is more than 1

8(x)=10

x=1.25

so each tic mark is 1.25 \

and since the K is on the 6th tic mark 1.25(6)=7.5 or 75%

or 8and 3/4 (in simplest form )

What is the perimeter of the figure

anastassius [24]

Answer:

Option A.

$P=73.4\ units$

Step-by-step explanation:

see the attached figure with letters to better understand the problem

In this problem we have a triangle with a circle inscribed in it

$A.F=A.B\\C.B=C.D\\E.F=E.D$

step 1

Find the length side B.C

$C.B=A.C-A.B$

substitute the given values

$C.B=23-14=9\ units$

step 2

Find the length side C.D

Remember that

$C.D=C.B$

therefore

$C.D=9\ units$

step 3

Find the length side E.D

we know that

$E.D=E.C-C.D$

substitute the given values

$E.D=22.7-9=13.7\ units$

step 4

Find the length side E.F

Remember that

$E.F=E.D$

therefore

$E.F=13.7\ units$

step 5

Find the length side A.F

Remember that

$A.F=A.B$

therefore

$A.F=14\ units$

step 6

Find the perimeter

$P=23+22.7+13.7+14$

$P=73.4\ units$

Standard printer paper has a thickness of 0.1mm. write an equation for a function that should approximately the thickness of a s

ladessa [460]

Folding a paper will make it thickness become double from it before.
Unfolded paper has 1 thickness
1 times folded paper has 2 thickness
2 times folded paper has 4 thickness
3 times folded paper has 8 thickness

From here it is clear that the pattern is $2^{n}$ . SInce the paper is 0.1mm, then the function would be:
f(n)= $2^{n}$ x 0.1mm

How many triangles can be constructed with the sides measuring 1m, 2m, and 2m.

Pachacha [2.7K]

Answer:Only one triangle can be constructed

Step-by-step explanation:

According to the question sides given are 1m, 2m and 2m

For the possibility of a triangle the sum of the two sides must be greater

than the third side

We have 1+2>2

⇒3>2

Also 2+2>1

⇒4>1

So the possibility of a triangle is fulfilled

Only an isosceles triangle can be constructed

as two sides are equal
