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

HELP PLS ITS DUE IN A FEW MIN
Tanya [424]

Answer:

S = 50w + 75

Step-by-step explanation:

After each week, Mike gains $50.

Letting w = 0 gives us the amount he started with. In this case, that would be $75.

Therefore, the equation is S = 50w + 75.

What’s the mean,median, and mode of 11,14,16,15,32,23,27,27,23,43 ?
alexdok [17]

Step-by-step explanation:

mean- add all number/by the total nos

=231/10=23.1

median - the middle value of data after arranging in ascending order

11,14,15,16,23,23,27,27,32,43

therefore the median is 23

mode - is the no that has occurred more

so mode will be 23 and 27

Pls help , need this done by tomorrow.
quester [9]

Answer:

Q matches to a and P matches to b

Step-by-step explanation:

This is a volume question so we can use the volume of a cylinder to see which one corresponds to what.  Volume of a cylinder is \pir^{2}h.  We know that the heights of the cylinders are the same since the diagram says so.  We also know pi is the same since thats a constant.  The only thing thats different is the radius (as you can see radius of P is bigger than Q).  If the radius of P is bigger than Q and all the other things are the same (height is the same and pi is the same), then that automatically means that P has more volume than Q.  More volume means more time to fill up.  Since Q has less volume, it will take less time to fill up.  So now we look at the graph.  A shows that the height of water increases at a faster rate than that of B.  This is because there is less volume in that container (less volume=less time to fill up).  Therefore a matches to Q and therefore b matches to P
