Answer:

The correct option is D) multiplication and addition

Step-by-step explanation:

Consider the provided information.

Ella had softball and dance practice for 4 weeks. She practiced softball 2 hours a week and dance 1 hour a week.

The number of hours she spend in 4 weeks for softball are:

4(2)

The number of hours she spend in 4 weeks for dance are:

4(1)

The total number of hours Ella practiced softball and dance are:

4(2)+4(1)

The operations that can be used to find the total number of hours are multiplication and addition.

Hence, the correct option is D) multiplication and addition

Answer:

1). t ≥ -\frac{3}{2}

2). k ≥ \frac{16}{3}

3). y < -\frac{1}{2}

4). b > \frac{250}{9}

5). w ≤ 0

Step-by-step explanation:

1). 14(\frac{1}{2}-t)\leq 28

   \frac{14}{14}(\frac{1}{2}-t)\leq \frac{28}{14}

   \frac{1}{2}-t\leq 2

   -t\leq 2-\frac{1}{2}

   -t\leq \frac{3}{2}

   t ≥ -\frac{3}{2}

2). 15k + 11 ≤ 18k - 5

   15k - 18k ≤ -5 - 11

   -3k ≤ - 16

   3k ≥ 16

     k ≥ \frac{16}{3}

3). 44y > 11 + 88y - 22y

    44y > 11 + 66y

    44y - 66y > 11

    -22y > 11

    22y < -11

    \frac{22y}{22}

    y < -\frac{1}{2}

4). \frac{7}{9}(b - 27) > \frac{49}{81}

    \frac{7}{9}(b - 27)\times \frac{9}{7} > \frac{49}{81}\times \frac{9}{7}

     (b - 27) > \frac{7}{9}

     b > \frac{7}{9}+27

    b > \frac{250}{9}

5). 11w - 8w ≥ 14w

    3w - 14w ≥ 0

    -11w ≥ 0

    w ≤ 0

A piece of metal has a mass of 2210 g. The volume of the metal is 260 cm³.
Vlada [557]

Answer:

density= 8.5\,\,\frac{g}{cm^3}

Step-by-step explanation:

Recall that the formula for density is:

density=\frac{mass}{volume}

therefore for this case we have:

density=\frac{mass}{volume} \\density=\frac{2210}{260} \,\frac{g}{cm^3} \\density= 8.5\,\,\frac{g}{cm^3}

a national park has two options: a $50 pass for all admissions during the year, or a $4 entrance fee each time you enter. Write
frutty [35]
<span>With the variable "y" being used to represent the total cost of going to the park for a year, the first equation would read "y = 50" since it is a one-time, flat cost. The second equation would be "y = 4x", with "x" being used to represent the number of times the person visited the park during the year multiplied by the $4 cost per visit.</span>
