Answer:

-5\frac{5}{8}

Step-by-step explanation:

Given : -2\frac{1}{4} and 2\frac{1}{2}

To Find : What is the product

Solution :

Numbers are  -2\frac{1}{4} and 2\frac{1}{2}

We are supposed to find the product

\Rightarrow -2\frac{1}{4} \times 2\frac{1}{2}

\Rightarrow \frac{-9}{4} \times \frac{5}{2}

\Rightarrow \frac{-45}{8}

\Rightarrow -5\frac{5}{8}

Hence the product is -5\frac{5}{8}

Question #7multiplechoice score: in a certain candy store, 3 pounds of candy and 2 pounds of mints cost $10.80, and 1 pound of c
irga5000 [103]
Let the cost of one pound of candy be x and one pound of mint be y.

3x+2y=10.8 a 
x+3y = 5.35  b 
 B*3 = 3x+9y = 16.05 b
 
b-a = 7y = 16.05-10.8= 5.25
           y = 5.25/7 = 0.75 

The cost per pound of mints is $0.75

Determine if the function is continuous to its domain
Maurinko [17]

Yes, it is continuous to its domain

<h2>Explanation:</h2><h2></h2>

In order to find the domain of the function we need to get the restrictions:

1. From natural log:

x>0

2. From quotient:

x\neq 0

Matching these two restrictions the domain is:

x\in (0,\infty)

So the function is continuous to its domain because is defined for every x-value in the interval (0, \infty))

A sphere and a cylinder have the same radius and height. The volume of the cylinder is 27 pi feet cubed.
LenaWriter [7]

Answer:

C. V = two-thirds (27)

Step-by-step explanation:

Given

Solid Shapes: Cylinder and Sphere

Volume of Cylinder = 27π ft³

Required

Volume of the sphere.

From the question,

<u>We have that</u>

1.  The volume of the sphere is the same as the volume of the cylinder

2. The height of the sphere is the same as the height of the cylinder.

From (2) above;

This means that the height of the cylinder equals the diameter of the sphere.

Let h represent the height of the sphere and d represent the diameter of sphere.

Mathematical, d = h

Recall that radius, r = r = \frac{d}{2}

Substitute h for d in the above expression

r = \frac{h}{2}. ----- (take note of this)

Calculating the volume of a cylinder.

V = πr²h

Recall that  V = 27; This gives us

27 = πr²h

Divide both sides by h

\pi r^2 = \frac{27}{h}

-------------------

Calculating the volume of a sphere

V = \frac{4}{3}\pi r^3

Expand the above expression

V = \frac{4}{3}\pi r^2 * r

Substitute \pi r^2 = \frac{27}{h}

V = \frac{4}{3} * \frac{27}{h} * r

Recall that r = \frac{h}{2}

So,

V = \frac{4}{3} * \frac{27}{h} * \frac{h}{2}

V = \frac{4}{3} * \frac{27}{2}

V = \frac{2}{3} * 27

V = \frac{2}{3} (27)

V = two-third (27)
