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

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

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

The regular price of a baseball hat is 14.45$. If Carlos buys the baseball hat on sale for 20% off the regular price, how much c

otez555 [7]

Answer:

$8.44

Step-by-step explanation:

To find the 20%

x/14.45=20/100

14.45×20=289

289÷100=2.89

We then subtract 2.89 from 14.45 to get the selling price.

14.45-2.89=11.56

$11.56 is the price of the baseball hat on sale.

To get the change

20-11.56=8.44

$8.44 is the change

I hope this helped! :)

What is the area of this trapezoid? 10cm 5cm 12cm 1.5cm

lutik1710 [3]

Area of a trapezoid = a+b+c x h

10 + 5 +12 = 27 x h

27h = 27 x 1.5 = 40.5
