Answer:

c) (-5, -7)

Step-by-step explanation:

In a parallelogram, the midpoints of the diagonals are the same point. This means ...

(R+T)/2 = (S+U)/2

R +T -S = U

(-6 +4 -3, -3 -1 -3) = U = (-5, -7)

Find x A) 12 B) 13 C) 11 D) 10

Soloha48 [4]

We know that the sum of arc ND and arc ML divided by 2 is equivalent to 6x + 23.

Thus, we can form an equation:

6x + 23 = (11x + 8 + 3x + 14)/2

Simplify:

6x + 23 = (14x + 22)/2

Simply again:

6x + 23 = 7x + 11

Subtract 6x from both sides:

23 = x + 11

Subtract 11 from both sides

x = 12

Option A, or x = 12

Question 5 (1 point)

Answer:

The area of sector AOB is 75.36 unit²

Step-by-step explanation:

Consider the provided information.

Circle O with minor arc AB=60 degrees and OA =12.

We need to find the area of sector.

Area of the sector: $A=\frac{\theta }{360} \times \pi r^2$

Substitute $\theta=60$ and r =12 in above formula.

$A=\frac{60}{360} \times 3.14\times (12)^2$

$=\frac{1}{6} \times 3.14\times 144$

$=24\times 3.14$

$=75.36$

Hence, the area of sector AOB is 75.36 unit²

Karen has 4h storyboiks. Karen's storybook collection is 2/3 of what Mary's collection is. How many storybooks do they have in a

Dafna11 [192]

In order to find out the answer , you just need to count :
Let's say that mary's collection is symbolized by x

2/3 x = 4h

x = 3/2 . 4h

x = 6h

The storybooks they have in total would be : 6h + 4h = 10 h

hope this helps
