Answer:
for second question
first length is 9cm
Area=l*b
= 9cm *9cm
=81<em><u>cm</u></em>
then, For semicircle
radius is 9 cm
area= 1/2*9cm
now , area of two semi circle = 2*1/2*9
= 9 cm
now area of shaded = 81-9
=72
That would be -20. a negative divided by a negative number is positive, positive divided by negative is negative bc even numbers of negatives make it positive. and ofc 20 x 5 = 100, hence the ‘20’
Answer:
6 units
Step-by-step explanation:
Use the distance formula, 
.
Plug the x and y values from the given points into the distance formula:
![\sqrt{([-4]-2)^{2}+(5-5)^{2}}](https://tex.z-dn.net/?f=%5Csqrt%7B%28%5B-4%5D-2%29%5E%7B2%7D%2B%285-5%29%5E%7B2%7D%7D)
.
Solve the square root:
= 
= 
Divide 259 by 7 (259/7)= 37 beads per necklace. If you wanted to check just multiply 7 and 37 (37x7)=259
I beleive it is 14 and 1 quarter in.
