You need to buy a 20-foot length of 15-wide carpet that costs $29.50 per square yard. How much will this cost?
Marianna [84]

The cost of the carpet will be $983.33

<h3>Calculating cost</h3>

From the question, we are to calculate how much the carpet will cost

From the given information,

The carpet has a length of 20 feet

and a width of 15 feet

First, we will covert the dimension to yard

NOTE: 1 foot = 1/3 yards

Thus,

20 feet = 20/3 yards

and

15 feet = 15/5 yards = 5 yards

Now, we will calculate the area of the carpet

Using the formula,

Area = Length × Width

Area of the carpet = 20/3 × 5 square yard

Area of the carpet = 33.33 square yard

Now, we have that

The carpet costs $29.50 per square yard

∴ The cost of the carpet = 20/3 × 5 × $29.50

The cost of the carpet = $ 983.33

Hence, the cost of the carpet will be $983.33

At the north campus of a performing arts school, 10% of the
Alecsey [184]

There were 600 students at the north campus and 400 students at the south campus.

<h2 /><h3><u>Calculus</u></h3>

To determine, if 42% of the 1000 students at the east campus are music majors, how many students did the north and south campuses have before the merger, the following calculation must be performed:

  • 0.10X + 0.90Y = 420
  • 1000 x 0.42 = 420
  • 500 x 0.10 + 500 x 0.90 = 50 + 450 = 500
  • 600 x 0.10 + 400 x 0.90 = 60 + 360 = 420

Therefore, there were 600 students at the north campus and 400 students at the south campus.

The function f is defined by f(x)=2x^2-4.<br> Find f(-x)
Vedmedyk [2.9K]
First of all, since all powers of x in this function are even, the entire function is even.  Thus, using -x as input doesn't change the function.  Thus, f(-x)=2x^2-4.

djverab [1.8K]

Answer:

The pizza of martin is \dfrac{4}{5}

Step-by-step explanation:

Given that,

Martin has \dfrac{5}{6} of pizza.

Liam has four time much pizza.

Let us consider pizza is x.

We need to calculate the how much pizza of martin

Using given data

Pizza of Martin =x\times\dfrac{5}{6}

Pizza of Liam = 4\times(\dfrac{5}{6}x)

The pizza of martin will be

Pizza\ of\ martin=\dfrac{\dfrac{20}{6}x}{\dfrac{20}{6}x+\dfrac{5}{6}x}

Pizza\ of\ martin =\dfrac{4}{5}

Hence, The pizza of martin is \dfrac{4}{5}
