Answer:

Step-by-step explanation:

so in this equation we have 2 variables, and we must figure out what those variables mean:

y: "y" is the total amount of money joe has after subtracting his debt from it

x: "x" is the # of months as the cost of each month(30) is placed just before this variable

as y is the total amount of money joe has we need to substitute it for 230 to figure out how long it took for joe to recieve that much money

230=30x-250

480=30x

x=16

it took joe 16 months to get $230

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

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

You buy a cylindrical container of salt with a diameter of 3.25 inches and a height of 5 inches. Your salt shaker is a cylinder

Sphinxa [80]

First calculate volume of the cylindrical container: Pi * R2 * H; where Pi is 22/7 or 3.147, R is the radius and H is the height of the container.

Vol of the cylindrical container: 3.147 * (3.25/2) * (3.25/2)* 5 = 41.55 inch 3

Volume of the shaker using the above principle:
3.147 * (1/2) * (1/2) * 1.5 = 1.18 inch 3

Number of times it can fill the salt shaker will be the ratio of the volumes:

= Volume of the cylindrical container divided by the volume of the shaker = 41.55 divided by 1.18

Answer is 35 times if rounded in absolute number.
