The cost per pound of flour and cost per ounce of flour is $0.195 per pound and 0.0121875 per ounces.

The cost per pound of flour = Cost of a sack of bread flour / Weight of a sack of bread flour

= $9.75 / 50 lbs

= $0.195 per pound

1 pound = 16 ounces

50 pounds = 50 × 16

= 800 ounces

The cost per ounce of flour = Cost of a sack of bread flour / Weight of a sack of bread flour

= $9.75 / 800

= 0.0121875 per ounces

This is the cost to acquire a unit of a good or service for a specific quantity that is purchased.

Therefore, the cost per pound of flour and cost per ounce of flour is $0.195 per pound and 0.0121875 per ounces.

The simplified value of the expression using only positive exponents is 9y⁶/x⁸

The expression is given as

(3 x⁻⁴ y³)²

Apply the law of indices to expand the bracket

So, we have

(3 x⁻⁴ y³)² = 3² * x⁻⁴*² y³*²

Evaluate the products of exponents

So, we have

(3 x⁻⁴ y³)² = 3² * x⁻⁸ y⁶

Evaluate the exponents

So, we have

(3 x⁻⁴ y³)² = 9 * x⁻⁸ y⁶

Apply the law of indices to rewrite negative exponent

So, we have

(3 x⁻⁴ y³)² = 9y⁶/x⁸

Hence, the simplified value of the expression using only positive exponents is 9y⁶/x⁸

9/29 < 1/a + 1/b < 7/12

Here we have two expression

3 < a < 4 and 4 < b < 5

We have to find the value of the expression

   1/a + 1/b

The lower bound of the expression is when we take the maximum value of both the expression  a and b

a = 4 and b = 5

 From this we get

= 1/ 4 + 1/5

= 5 + 4 / 20

9/ 20

In the same way, we get the higher bound of the expression taken by taking  the minimum value of both the expression a and b

a = 3 and b = 4

By putting the value of a and in the expression we get:

1/ 3 + 1/4

= 4+3 / 12

= 7/12

Thus we get the possible value of the expression :

9/20 <1/a + 1/b < 7/12

A Venn diagram uses circles that overlap each other to show logical relationships between two or more sets of items. The relationship that is being illustrated with this Venn diagram is the relationship between natural numbers and numbers less than 5.

A natural number includes all positive numbers from 1 to infinity. Natural numbers does not include zero (0). The sample space represents all the possible sets of outcome. In mathematics, a set can be described as a collection of objects whose elements are fixed and cannot be changed.

The probability of selecting a number less than 5 = numbers less than 5/ total numbers

5 / 8

The probability of spinning a natural numbers = all natural numbers / total numbers

7/8

The probability of spinning natural numbers and numbers less than 5 = 4/8 = 1/2

A' = 5,6,7

Answer:

Answer: (t-r) / 21 = -0.857    where,   t= -6 and r= 12

Step-by-step explanation:

Given data,

t-r divided by 21

where, t= -6 and r= 12

So, we can write,

                            = (t-r) / 21

Let us assume,

                  (t-r) / 21 = x

So,

           x = (t-r) / 21 { t = -6 and r = 12             (eq-1)

         x = (t-r) / 21

We can substitute,    t = -6 and r = 12   values in this equation 1

so, we can write,

                            x =   (t-r) / 21

                            x = (-6-12) / 21

                            x = -18/21

                            x = -6/7

                            x = -0.857

Therefore,

                       (t-r) / 21 = -0.857    where,   t= -6 and r= 12

The length of the rectangle is 6 meters and the width is 2 meters.

Perimeter is the sum of the lengths of all the sides of a given 2D plane figure.

A rectangle area has a length that is 4 more than its width.

Assuming the width of the rectangle to be x meter,

∴ The length of the rectangle is (x+4) meters.

Also given that the rectangle area is 12 sq meters.

We know, that the area of a rectangle is a product of its length and width.

∴ [ x × (x+4) ] = 12.

x² + 4x = 12.

x² + 4x - 12 = 0.

x² + 6x - 2x - 12 = 0.

x(x+6) -2( x+6) = 0.

(x+6)(x-2) = 0.

x + 6 = 0 Or x - 2 = 0.

x = -6 or x = 2.

We know distance can not be negative so, x = -6 is inadmissible.

So, the width of the rectangle is 2 meters and length is (x+4) = (2+4) = 6 meters.

Then

[tex]z^{\prime }=e^{i\frac{3\pi }{2} }\times z[/tex]

Then

x' + iy' = (0 -i)×(x + iy)

Then

x' + iy' = (-i) × (x + iy)

Then

x' = y and y' = -x

Then

R transform M(x , y) to the point M'(y , -x)
