If the cost to purchase and install carpet is $4 per square foot, how much will it cost to put carpet in the family room and hal
andrey2020 [161]

The first step is to section the given daigram. It would be shown in the diagram below

Looking at the diagram,

Area of family room = 5.5 * 24 = 132 square feet

Area of hallway = 15.5 * 4 = 62 square feet

Total area to be covered with carpet is

132 + 62 = 194 square feet

Since the cost per square foot is $4, then the cost of putting carpet in the family room and hallway is

194 * 4 = $776* 4 = $776

A ball rolls down an inclined plane such that the distance (in centimeters) that it rolls in t seconds is given by s(t) = 2t^3 +
IRISSAK [1]
The ball's velocity will be represented by the derivative of its distance function:

s'(t)=6t^2+6t

Now find the times t for which this is equal to 30, i.e. solve

6t^2+6t=30\implies t^2+t-5=0

This has two solutions, t=-\dfrac{1\pm\sqrt{21}}2, but only one is positive and falls in the interval [0,3]. So the velocity reaches 30 cm/s when t=-\dfrac{1-\sqrt{21}}2\approx1.79.

There are 15 people on a basketball team, and the coach needs to choose 5 to put into
snow_lady [41]

Answer:

The coach can do this in 3,003 ways

Step-by-step explanation:

Here, the coach needs to select a team of 5 from a total of 15 players

Mathematically, the number of ways this can be done is simply 15 C5 ways

Generally, if we are to select a number of r items from n items, this can be done in nCr ways = n!/(n-r)!r!

Applying this to the situation on ground, we have;

15C5 = 15!/(15-5)!5! = 15!/10!5! = 3,003 ways
