Using proportions, it is found that the better deal, on a per ounce basis, is given by:

  • A a 30 oz. box of Tasty Wheats for $4.20

<h3>Proportion</h3>
  • To find the better deal, we use <em>proportions </em>to find the cost per ounce, that is, dividing the cost per the amount of ounces. The <em>better deal </em>is the one with the smaller cost per ounce.

For each option, the costs per ounce are given by:

  • A a 30 oz. box of Tasty Wheats for $4.20:

C_a = \frac{4.2}{30} = 0.14

  • B a 24 oz. box of Cherry Oats for $3.60

C_b = \frac{3.6}{24} = 0.15

  • C a 42 oz. Box of Giganto Flakes for $6.30

C_c = \frac{6.3}{42} = 0.15

  • D a 42 oz. Box of Giganto Flakes for $6.30

C_d = \frac{6.3}{42} = 0.15

Due to the <em>smaller cost</em>, option A is the better deal.

NikAS [45]

Answer:

1.5 seconds

Step-by-step explanation:

plug 0 in for y

0=-16t^2+36

then slove for t

-36=-16t^2

-36 / -16 = 9/4

9/4=t^2

square root of 9/4 is 3/2 or 1.5

t=1.5

Construct a frequency distribution and a frequency histogram for the data set using the indicated number of classes. Describe an
elena-s [515]

Answer and Explanation:

Number of classes = 8

    Highest value =2300

  Lowest value = 1250

Class width= highest value – lowest value / number of classes

               = 2300 – 1250/8

                = 131.25 = 132

So, we can write class as 1250+132=1382

Class                                        frequency

1250-1382                                 2

1382-1514                                 3

1514-1646                                 6

1646-1778                                 2

1778-1910                                 3

1910-2042                                 2

2042-2174                                 1

2174-2306                                 1

Find the length of the leg(s) of a right triangle, to the nearest hundredth, if both legs are equal and the hypotenuse is 10.
charle [14.2K]

Answer:

7.07 units

Step-by-step explanation:

Use the Pythagorean theorem for the right triangle:

\text{hypotenuse}^2=\text{leg}_1^2+\text{leg}_2^2,\\ \\c^2=a^2+b^2.

If a = x, b = x, and c = 10, then

10^2=x^2+x^2,\\ \\100=2x^2,\\ \\x^2=50,\\ \\x=\sqrt{50}=5\sqrt{2}\approx 7.07\ units.
