5 packets of pencils would only be enough for 25 students because 5×5=25 so to get enough for the remaining 2 students you need to buy an extra packet thus buying 6 packets to be enough for 27 students

Question 28 of 30Calculate the surface area in square feet of a box that measures 13 inches inlength, 11 inches in width, and 11

KATRIN_1 [288]

ANSWER:

5.65 ft²

STEP-BY-STEP EXPLANATION:

We have the following measures:

Length (l) = 13 inches

Width (w) = 11 inches

Height (h) = 11 inches

We can determine the surface area as follows:

$\begin{gathered} A=2\cdot l\cdot w+2\cdot l\cdot h+2\cdot w\cdot h \\ \\ \text{ We replacing:} \\ \\ A=2(13)(11)+2(13)(11)+2(11)(11) \\ \\ A=286+286+242 \\ \\ A=814\text{ in}^2 \\ \\ \text{ Convert inches to feet, knowing that 1 foot is equal to 12 inches} \\ \\ A=814\text{ in}^2\cdot\frac{(1\text{ ft\rparen}^2}{(12\text{ in\rparen}^2} \\ \\ A=5.65\text{ ft}^2 \end{gathered}$

Therefore, the correct answer is 5.65 ft²

Identify the initial amount and the growth rate of the following:<br> Y = 9.8 (1.35)^t

stiv31 [10]

Assuming t is a time unit.
The initial amount is when t = 0, so it is 9.8 * 1 = 9.8. The growth rate is how much the amount goes up by for every increase of 1 in t. This is 1.35 because that is the part being affected by t. we plug in 0 for t to get 9.8 as the initial amount. The growth rate is just 135% factor, or 35% more each time, because 1.35 is the base of the exponent.
