Say that n=4. Casey has 4 nickles, and Megan has 4x4, or 16 nickles. Combined, they have 20 nickles, or (5x4) nickles. Answer is 5n.

HELP PLEASE I NEED HELP WILL MARK BRAINLIEST

krek1111 [17]

4 is B.

5 is true.

6- Statement 3: NO and ON are the same line. They are congruent by the reflexive property (a line segment is a reflection of itself)

Statement 4: Shape MNO and shape PON are congruent by side-side-side since:

side PN = side MO

side MN = side PO

side NO = side ON

So the answer would be D

Hope that helps!

A pinwheel design for a quilt is shown at the right. Each square of the design has a side length of 3 inches. May someone help m

arlik [135]

Answer:

Part A) The area total of the design is $144\ in^{2}$

Part B) The total area of the four large shaded triangles is $72\ in^{2}$

Part C) The cost to purchase the material to make the triangles for the quilt will be $\$172.8$

Step-by-step explanation:

Part A) Find the area total of the design

The area total of the design is a square

so

To find the length side of the square design multiply the number of squares by 3 in

$a=(4*3)=12\ in$

$A=(a)^{2}$

$A=(12)^{2} =144\ in^{2}$

Part B) Find the total area of the four large shaded triangles

the area of the four large triangles is equal to

$A=4[\frac{1}{2}(b)(h)]$

we have that

$b=(2*3)=6\ in$

$h=(2*3)=6\ in$

substitute

$A=4[\frac{1}{2}(6)(6)]=72\ in^{2}$

Part C) How much will it cost to purchase the material to make the triangles for the quilt ?

To find the cost multiply the area of each design of four large triangles by 30 and then multiply by $0.08 per square inch

The cost is equal to

$30(0.08)(72)=\$172.8$

What is the equilibrium price per DVD?

OleMash [197]

The equilibrium referred to here is the dynamic equilibrium. It means that there is a change happening, but the opposite change are equal so they cancel out. So, we can determine the equilibrium price at the point where the demand and supply curve intersect. That would be at the quantity of 60 units. Therefore, the equilibrium price is $10.
