Answer:

\boxed{43.48 \, \%}

Step-by-step explanation:

The formula for calculating percentage is

\text{Percentage} = \dfrac{\text{Part }}{\text{Whole}} \times 100 \, \%

The "part" is the number of single-shot espressos

The "whole" is the total number of espressos.

\begin{array}{rcl}\text{Total espressos} & = & 46\\\text{-Single-shot espressos} & = & 26\\\text{Double-shot espressos} & = & 20\\\end{array}

\text{ \% Double-shot}=\dfrac{20}{46} \times 100 \, \% =\mathbf{43.48 \, \%}\\\\\boxed{\mathbf{43.48 \, \%}} \text{ of the espressos were double-shot}

The perimeter of a building is 900 feet. If the length of the building is 400 feet, find the width. How many lights will be need
Helen [10]

Answer:

The width of the building is 50 lamps and 60 lamps will be needed.

Step-by-step explanation:

The perimeter is computed by the sum of the sides of the building, since the length and width are equal on the oposite sides of the building, the perimeter is given by:

perimeter = 2*length + 2*width

900 = 2*(400) + 2*width

2*width + 800 = 900

2*width = 900 - 800

2*width = 100

width = 100/2 = 50 feets

To know how many lights bulbs will be needed we need to take the perimeter of the building and divide it by the space between the lamps. We have:

number o lamps = 900/15 = 60 lamps

Find the domain of the graphed function?
MariettaO [177]

<span>Remember, the domain of a function is all of the x values in the (x,y) coordinates. For this, let’s take a few bench mark coordinates. (0,0) (1,2.5)(2,0) (3, -9). Those definitely aren’t all real numbers, so eliminate A. X is not only less than or equal to 0, so eliminate C. </span>

<span>It’s B.</span>
