While driving in Hawaii, Momo discovered some silver bars on the ocean floor. Each bar weighed 70 pounds and the price of silver
Anni [7]

1 pound = 16 ounces.

70 x 16 = 1120 total ounces per bar.

1120 x $5.05 = $5,656 each.

8/f = 56/105 what is f?
svetlana [45]
8/15 = 56/105

This may be solved using proportion.
a/b = c/d
ad = bc   where cross products are equal.

a = 8
b = f
c  = 56
d = 105

ad = bc
8*105 = f*56
840 = 56f
840/56 = 56f/56
f = 15

56 ÷ 7 = 8
105 ÷ 7 = 15

A circular pen has an area of 64<img src="https://tex.z-dn.net/?f=%20%20%5Cpi%20" id="TexFormula1" title=" \pi " alt=" \pi " a
Allisa [31]
What we know:
shape is circular
Area=64π yr²
Area=πr²
circumference=2πr

In order to find circumference we need r=radius. We can use the area to find r by solving for r using substitution of the information we know above.

Area=πr²
64π=πr²                         substitution
64π/π=π/πr²                  multiplicative inverse
64=r²
√64=√r²                          properties of radicals
8=r                     We would get two solutions, a positive and negative one                          but we will only use the positive solution since radius is positive

Circumference=2πr
C=2π(8)=16π yards

Please assist me with the domain and range of graphs​
Sphinxa [80]

Answer:  see below

<u>Step-by-step explanation:</u>

Domain represents the x-values from the smallest (furthest left) to the biggest (furthest right).

Range represents the y-values from the lowest (furthest down) to the highest (furthest up).

Interval notation: If a value is included <em>(closed dot)</em>, use a bracket [  ]

                      If a value is NOT included <em>(open dot)</em>, use a parenthesis (  )

                     Note that ± ∞ is never included.

1. Domain: smallest x-value is -4 (included). biggest x-value is 3 (included)

  Range: lowest y-value is 2 (included). highest y-value is 5 (included)

                 D: x = [-4, 3]        R: y = [2, 5]

2. Domain: smallest x-value is -∞ (←). biggest x-value is 2 (included)

  Range: lowest y-value is 2 (included). highest y-value is ∞ (↑)

                 D: x = (-∞, 2]        R: y = [2, ∞)

3. Domain: smallest x-value is -∞ (←). biggest x-value is ∞ (→)

  Range: lowest y-value is -∞ (↓). highest y-value is ∞ (↑)

                 D: x = (-∞, ∞)        R: y = (-∞, ∞)

4. Domain: smallest x-value is -∞ (←). biggest x-value is ∞ (→)

  Range: lowest y-value is -∞ (↓). highest y-value is 4 (included)

                 D: x = (-∞, ∞)        R: y = (-∞, 4]

5. Domain: smallest x-value is -∞ (←). biggest x-value is ∞ (→)

  Range: lowest y-value is 3 (included). highest y-value is ∞ (↑)

                 D: x = (-∞, ∞)        R: y = [3, ∞)

6. Domain: smallest x-value is -2 (included). biggest x-value is ∞ (→)

  Range: lowest y-value is -3 (included). highest y-value is ∞ (↑)

                 D: x = [-2, ∞)        R: y = [-3, ∞)
