The answer is B because the 118° is curvy so the straight lines would be kess than 118 so its B because D is too short :)

Mary Sue and Betty have 603 necklaces altogether. Mary Sue has 115 more necklaces than Betty. How many necklaces does Betty have

Blizzard [7]

Let Mary Sue have m necklaces and Betty have b necklaces.

And they have 603 necklaces altogether, that is

m + b =603

And Mary Sue has 115 more necklaces than Betty, that is

m=b +115

Substituting this value in first equation we will get

b+115+b=603

Subtracting 115

2b= 488

b= 244

So Betty have 244 necklaces .

What is f–1(8)?? Please select the best answer

notka56 [123]

Answer:

$f^{-1}(8)=\frac{3}{2}$

Step-by-step explanation:

Given f(x)= $2x+5$

We have to find $f^{-1}(8)$

In order to find $f^{-1}(x)$ we have to make x as the subject of the formula

Let us assume f(x)=y

⇒ $2x+5=y$

Subtracting both sides by 5

$2x+5-5=y-5$

$2x=y-5$

Dividing both sides by 2

$\frac{2x}{2}=\frac{y-5}{2}$

⇒ $x=\frac{y-5}{2}$

Now substituting y with x

we have $f^{-1}(x)=\frac{x-5}{2}$

Now $f^{-1}(8)=\frac{8-5}{2}$

= $\frac{3}{2}$

So option (ii) is correct

Help me please I’m having trouble with it

Given:

Measure of arcs 50°, 115° and 85°

To find:

The measure of the numbered angle 5.

Solution:

Let the missing arc measure be A.

The arc measure of a full circle is 360°

m(ar A) + 50° + 115° + 85° = 360°

m(ar A) + 250° = 360°

Subtract 250 from both sides.

m(ar A) = 110°

If two chords intersects inside a circle, then the measure of the angle formed is half of the sum of intercepted arcs.

$$\Rightarrow m\angle 5 =\frac{1}{2} (110^\circ+115^\circ)$

$$\Rightarrow m\angle 5 =\frac{1}{2} (225^\circ)$

$$\Rightarrow m\angle 5 =112.5^\circ$

The measure of the numbered angle is 112.5°.
