How much will you save per lb, by buying the least expensive? Round to the nearest cent. 2.5 lbs for $8.75 or 3 pounds for $9.75.

Answers

Answer 1
Answer:

Answer:

$0.25 per pound.

Step-by-step explanation:

Let us find unit rate for both quantities.

\text{Price per pound}=\frac{8.75\text{ dollars}}{2.5\text{ pound}}

\text{Price per pound}=3.5\frac{\text{ dollars}}{\text{ pound}}  

Therefore, cost of per pound for first given rate is $3.5.

Now let us find unit rate for second quantity.

\text{Price per pound}=\frac{9.75\text{ dollars}}{3\text{ pound}}

\text{Price per pound}=3.25\frac{\text{ dollars}}{\text{ pound}}

We can see that price for second quantity is less than 1st. To find the savings per pound we will subtract 3.25 from 3.5.

\text{Savings per pound}=3.50-3.25

\text{Savings per pound}=0.25

Therefore, we will save $0.25 per pound by buying the least expensive.

A Geometry student says I got lost in that lesson I wrote down that AD/AB eQUALS AC/ab but I have no idea where comes from

Answers

Answer:

AD/AB = AB/AC

Step-by-step explanation:

If we take two triangules in that figure: ABC and ABD, both are triangles rectangles. We need to use the definition of cosine, with the angle in th A corner, we called ∅.

For the ABC triangle: cos(∅) = adjacent cathetus/hypotenuse = AD/AB

For the ABD triangle: cos(∅) = adjacent cathetus/hypotenuse = AB/AC

Then:

cos(∅) = AD/AB = AB/AC

The sum of interior angle of a regular polygon is 1980 . Find its angle .

Answers

The sum of the angles of any polygon with 'n' sides is (n - 2) times 180 degrees.

1980 / 180 = 11 , so the polygon has 13 sides and 13 angles.

If the polygon is regular, then all the angles are equal.

Each interior angle is 1980/13 = 152.308 degrees (rounded)

you are saving $30 each month. you have a goal to accumulate $700 in savings. how long will it take you?

Answers
