To compare let's use Algebra to see how much one ounce costs for each package:

1. <u>16 ounces </u>= <u>$.79 </u>
       1 ounce       $x

$x= 0.049

2. <u>32 ounces</u> = <u>$3.49</u>
     1 ounce         $x

$x = 0.109

Therefore, comparing #1 and #2, the first package is the better deal.

The dictionary is 3 inches thick. What is the volume of the dictionary
Yuki888 [10]

Answer:

Square shaped = 27 cubic inches , Rectangular shaped = 3LW cubic Inches

Step-by-step explanation:

If the dictionary is a square ( all sides are equal ) the the volume is

      V = Length * Length * Length = L^{3}

      V = 3 * 3 * 3 = 27 inch^{3}

while if its rectangular ( all side are not equal ) shaped

      V = Length * Width * Height (thickness)

      V = L * W * 3 = 3LW inch^{3}

Help please with this math ;-; I beg of you
RSB [31]

Answer:

49 - 9π

Step-by-step explanation:

Area of white portion = area of triangle - area of circle

To find the area of the triangle:

The area of a triangle can be calculated using this formula

A=\frac{bh}{2} where b = base length and h = height

The height given is 7m and the base length given is 14m

That being said we plug in the given values into the formula

\frac{14*7}{2} \\14*7=98\\\frac{98}{2} =49

Hence, the area of the triangle is 49 sq meters.

To find the area of circle

( note that the area is in terms of pi; shown by the answer choices. )

Formula for area of a circle = A=\pi r^2

We are given the diameter  ( 6m )

However, we need the radius

To convert diameter to radius we divide by 2

6/2 = 3 so the radius = 3m

Now we plug in 3 into the formula

A=\pi 3^2\\3^2=9\\A=9\pi

Remember we do not apply pi because the answer should be in terms of pi.

Now we subtract the two

Area of white portion = 49 - 9π

Hence, the answer is A

11Alexandr11 [23.1K]

Answer: Rate of A: 5/6

Rate of B: 3/5

A has a higher rate of change

Step-by-step explanation: You calculate slope/rate of change by determining the rise over the run. The rate of change in A is 5/6x, this is bigger than the slope of B.
