Tom [10]

Answer:

-9.4

Step-by-step explanation:

–5.3+(-4.1) =

The signs are alike, so we add and take the sign

5.3+4.1 = 9.4

The sign is negative so we take the negative sign

-9.4

What is the circumference
Stolb23 [73]
There are two (equivalent) formulas for the circumference of a circle:

C = 2 pi r, where r is the radius of the circle

C = pi d, where d is the diameter of the circle

In this particular problem, however, we're dealing with arc length.  For the shown central angle "theta" = 160 degrees, the arc length is 42 cm.
Knowing this enables us to calculate the radius or diameter of the circle.

Arc length = s = (radius) (central angle, in radians, not degrees)

First, convert 160 degrees to radians:  160 deg     pi rad
                                                              ----------- * ------------ = (8/9) pi rad
                                                                    1         180 deg

Then 42 cm =  r *(8/9) pi rad

Solve for the radius (r):  divide 42 cm by (8/9) pi rad

Then use the formula for circumference introduced earlier:

C= 2 pi r                   Substitute [42 cm / ( (8/9) pi rad )] for r.

Simplify your result, and you will then have the circumference, C, in cm.

Anyone know? <br> A. 99 <br> B. 100 <br> C. 121<br> D. Cannot be determined
Verizon [17]

Since, it is given that the pentagon ABCDE is congruent to pentagon FGHIJ.

By being congruent, the corresponding angles and sides are equal.

Therefore, \angle A = \angle F, \angle B = \angle G, \angle C = \angle H, \angle D= \angle I, \angle E = \angle J.

By using \angle A = \angle F

So, 100^\circ = \angle 1

Therefore, the measure of angle 1 is 100 degrees.

So, Option B is the correct answer.
