alekssr [168]

Given the number of espresso sold at Chestnut Hill Coffee Cafe as either a single-shot or a double-shot, the percentage of double-shot espressos sold is 43.48%.

<h3>What percentage of the espressos were double-shot?</h3>

Percentage is simply number or ratio expressed as a fraction of 100.

It is expressed as;

Percentage = ( Part / Whole ) × 100%

Given the data in the question;

  • Total number of espressos sold or Whole = 46
  • Number of single-shots or Part single = 26
  • Number of double-shots or Part double = 46 - 26 = 20
  • Percentage of double-shot = ?

Percentage = ( Part / Whole ) × 100%

Percentage = ( Part double / Whole ) × 100%

Percentage = ( 20 / 46 ) × 100%

Percentage = 0.43 × 100%

Percentage = 43.48%

Given the number of espresso sold at Chestnut Hill Coffee Cafe as either a single-shot or a double-shot, the percentage of double-shot espressos sold is 43.48%.

the national flag of scotland has a white diagonal on a blue backround Tracy is sewing a scottish flag she knows that the length
dybincka [34]

Answer:

12 feet

Step-by-step explanation:

By Pythagoras theorem, a²+b²=c², where c represents the diagonal and a and b represents the other sides of a right angled triangle

As a flag is a rectangle, the two triangles cut would be  right angled triangles

Therefore, a²+9²=15²

a²+81=225

a²=144

a=√144

a=12 feet

A rectangle has a height of 5 and a width of 4x^2 – 2x – 6.
bogdanovich [222]

The area of the rectangle is 20x^{2} -10x-30 units.

Step-by-step explanation:

Step 1:

The area of a rectangle is obtained by multiplying the length with the width of the rectangle.

Considering this a whole rectangle, the length of the rectangle is 5 units and the width is the sum of 4x^{2}, -2x, and -6.

So the length of the rectangle = 5 units and

the width of the rectangle = 4x^{2} -2x-6 units.

The area of a rectangle = (length)(width).

Step 2:

By substituting the known values, we get

The area of the rectangle = (5) (4x^{2} -2x-6) = 20x^{2} -10x-30.

So the area of the rectangle is 20x^{2} -10x-30 units.

What is the volume of a hemisphere with a radius of 61.9 m, rounded to the nearest
ZanzabumX [31]

Answer:

The volume of the hemisphere is 496741.6 m³

Step-by-step explanation:

The volume of an sphere is given by:

V_{s} = \frac{4\pi r^{3}}{3}

In which \pi = 3.14 and r is the radius.

An hemisphere is half of an sphere, so it's volume is half the sphere's volume. So

V_{h} = \frac{V_{s}}{2} = \frac{2\pi r^{3}}{3}

In this question:

r = 61.9. So

V_{h} = \frac{2\pi (61.9)^{3}}{3} = 496741.6

The volume of the hemisphere is 496741.6 m³
