Althea's plans for saving $384 plan amount to save number of each week weeks needed $20 $30 $50 20 using plan b, how many weeks will it take althea to reach her savings goal? write an equation to model your work

13 weeks

Step-by-step explanation:

In the picture attached, data of the problem is shown in a table.

Althea wants to save $384, in plan B she saves $30 each week. The amount of weeks needed is obtained dividing the total amount to save by the amount saved per week, that is:

equation: $384÷$30  = 12.8 weeks

Here, weeks are considered integers, so you have to round this value to the next integer, that is, 13 weeks. To better understand this, suppose you take 12 weeks saving $30 per week, after 12 weeks you will save: $30*12 = $360, which is not enough; with 13 weeks you will save: $30*13 = $390.

d. it is a convex pentagon because it has five sides and none of the sides would extend into the inside of the polygon.

step-by-step explanation:

d. $180

step-by-step explanation:

if the dimensions of the room is 9ft by 12 ft, we have the area of the floor as,

so the area of the floor is 108 square feet, converting that into square yards we get,

the cost of carpet is $15 per square yard, therefore the cost of carpet for 12 square yards is,

hence, the cost of carpet is $180.

assuming the dimensions of the room be,

15 ft by 12 ft

so, the area of the floor of that room is,

we can convert 180 square feet into square yards, we know that,

1 sq ft = 0.111 sq yard

so, 180 square feet is,

so the area of floor is 20 square yards.

now, the cost of carpet is 15 dollars per square yard, therefore the cost of carpet for 20 square yards is,

so, it will cost $300.
