2 answers:

8 0

If you would like to calculate g * 5 - h * 3 for g = 2 and h = 7, you can do this using the following step:

g = 2
h = 7
g * 5 - h * 3 = 2 * 5 - 7 * 3 = 10 - 21 = - 11

The correct result would be - 11.

Let A= {a,b,c,d,e} and let B= {1,2,3,4,5} determine n(AxB)

777dan777 [17]

n(AxB) = 25

Step-by-step explanation:

AxB in sets is called Cartesian product. And is defined as a set of ordered pairs (a,b) where a belongs to A and b belongs to B.

Given

A = {a,b,c,d,e}

B = {1,2,3,4,5}

The number of elements for Cartesian product of two sets is determined by:

$n(AxB) = n(A) * n(B)$

Here

$n(A) = 5\\n(B) = 5$

So,

$n(AxB) = 5*5 = 25$

Hence,

n(AxB) = 25

Stella bought 14 purses for $50. The next day she bought 2 more for a total of $38. What was the mean cost per purse?

denpristay [2]

Answer:

$48.5

Step-by-step explanation:

Given data

Number of purses= 14+2= 16

Cost of 14 purses= $50

Cost of 2 purses= $38

Let us use the weighted cost method

Mean cost = (14*50+ 2*38)/16

Mean cost = (700+ 76)/16

Mean cost = 776/16

Mean cost =$48.5

The length of a rectangle is twice its width. The perimeter of the rectangle is 30 cm. What are the length and width? a) Set up

Helga [31]

Answer:

10 cm and 5 cm

Step-by-step explanation:

a) Set up the variables:

Let x represent the width; Then 2x will represent the length.

b) What is the equation that represents the above situation?

Use perimeter formula:

P = 2( l + w)

As we set up w = x and l = 2x, and we know that the perimeter is 30 cm, we can build an equation by substituting the values we know or set up:

30 = 2( 2x + x)

c) solve the equation

30 = 2( 2x + x)
30 = 2(3x)
30 = 6x
x = 30/6
x = 5

d) the length and width are?

The width is 5 cm and the length is twice the width, 5*2 = 10 cm
