First you find the circumference... 2pi*r... and then you multiply that by 2.125. To find out the total amount of meters that the man walks!

We are given radius of circle as 4m.

Now if a man walks around a circle means we are considering the circumference here.

Circumference of circle can be found with the formula:

$Circumference = 2* \pi *r$

Where r = radius of circle and pi = 3.14

plugging these values in the formula ,

$Circumference = 2* 3.14 *4$

Circumference = 25.12 m

Now distance covered by man when he walks around the circle once = 25.12m

distance covered by man when he walks around the circle 2.125 times = 25.12 *2.125 = 53.38 m

Answer : 53.38 m

One angle of an isosceles triangle measures 110°. Which other angles could be in that isosceles triangle? Choose all that apply.

andre [41]

Answer:

Therefore the correct option is 2. 35 degree.

$\angle ABC=\angle ACB=35\°$

Step-by-step explanation:

Consider an Isosceles Triangle, Δ ABC where,

∠BAC = 110°

TO Find:

∠ ABC = ∠ACB = ?

Solution:

For an Isosceles Triangle

Base Angles are equal

∴ $\angle ABC=\angle ACB=x\ (say)$

Now,

Triangle sum property:

In a Triangle sum of the measures of all the angles of a triangle is 180°.

$\angle A+\angle B+\angle C=180\\\\110+x+x=180\\\therefore 2x=180-110=70\\\therefore x=\dfrac{70}{2}=35\°$

Therefore,

$\angle ABC=\angle ACB=35\°$

Lindsay owns one-third the number of books that Destiny owns. Henry owns a fourth as many books as Destiny. Together they own 57

vovikov84 [41]

Answer:

Lindsey owns 12 books

Step-by-step explanation:

1/3x:Lindsay

x:Destiny

1/4x: Henry

1/3x+1/4x+x=57

4/12x+3/12x+x=57

7/12x+x=57

19/12x=57

x=57*12/19

x=36

1/3x=36/3

1/3x=12

Nicole deposited $2,000 at 6% simple interest. How long will it be before she has $2,600 in her account?

Kryger [21]

FV=PV(1+r)ⁿ

FV=Future Value, or the $2,600 that you want.
PV=Present Value, or the value that you are depositing.
APR: .06

2,600=2,000(1.06)ⁿ
2,600=2120ⁿ
It would take about a year for Nicole to get $2600.

~Hope I helped~

Answer:

$b = 17$

Step-by-step explanation:

For this triangle we have to

$a=18.2\\B=62\°\\C=48\°$

We want to find the length of b

We know that the sum of the internal angles of a triangle is 180 °

$A + 62 +48=180\\\\A=180-62-48\\\\A=70\°$

Now we use the sine theorem to find the length of b:

$\frac{sin(A)}{a}=\frac{sin(B)}{b}=\frac{sin(C)}{c}$

Then:

$\frac{sin(A)}{a}=\frac{sin(B)}{b}\\\\b=\frac{sin(B)}{\frac{sin(A)}{a}}\\\\b=a*\frac{sin(B)}{sin(A)}\\\\b=(18.2)\frac{sin(62)}{sin(70)}\\\\b=17$
