Please help Asap will mark (Brainliest)
nadezda [96]

Answer: The area of the notebook that the sticker covers is 128 cm^2

Step-by-step explanation:

The equation for the area of a rectangle should be:

A=bh

-The height of the stickers measures 16 cm:

height = 16cm

-So, if the base is half as long as the height, you divide it by 2:

base=\frac{16}{2}=8cm

-Then, you substitute it:

A=16 · 8

-Result:

128cm^2

Find the perimeter of OQR if OQ=6.5.<br> A.<br> 6.1<br> B.<br> 12.2<br> C.<br> 13<br> D.<br> 19.1
Svetach [21]

ANSWER


The correct answer is 19.1


EXPLANATION


The perimeter of triangle OQR is the sum of the distance around the triangle.



Thus,


Perimeter=|OQ|+|OR|+|RQ|



We can observe that two of the angles are equal.



The angles that are equal measures 62° each.



Therefore triangle OQR is an isosceles triangle. This means that



|OQ|=6.5=|OR|



Hence,



Perimeter=6.5+6.5+6.1




Perimeter=19.1 units.

Answer:

given data

bond  = $5000

coupon rate = 4.6%

purchased bond = $5195

to find out

yield of this new bond

solution

We get here first amount paid to the bond holder

amount paid = 4.6% × $5000

amount paid = $230

and

so Tim earned $230 on a bond that cost her $5195  

so yield of this new bond = \frac{230}{5195} \times 100

yield of this new bond = 4.42 %
