16-pound bag of Kitty Kibbles is $24.00. An 8-pound bag of Feline Flavor is $11.20. Which statement about the unit prices is true?

Answers

To find the unit price you divide the total cost of the bag by the amount of pounds in the bag.

Thus, the unit price of Kitty Kibbles is 24/16, or 1.5. This means that each pound of Kitty Kibbles costs $1.50.

Also, the unit price of Feline Flavor is 11.20/8, or 1.4. This means that each pound of Feline Flavor costs $1.40

Feline Flavor is cheaper per pound than Kitty Kibbles (or Kitty Kibbles is more expensive than Feline Flavor per pound).

Answer:

Kitty Kibbles has a higher unit price of $1.50/ pound

The perimeter of a rectangle is 34 units. Its width is 6.5 units.Write an equation to determine the length (L) of the rectangle.

Answers

Answer:

10.5 units

Step-by-step explanation:

From the question;

Perimeter of a rectangle is 34 units
Width of the rectangle is 6.5 units

We are supposed to determine the length of the rectangle;

We know that the perimeter of a rectangle is given by;

P = 2(L+W), where L is the length and W is the width.

Therefore, in this case;

34 units = 2(L + 6.5 units)

We get;

34 units = 2L + 13

Solving for L,

2L = 34 - 13

2L = 21

L = 10.5 units

Thus, the length, L, of a rectangle is 10.5 units

Factor:

a^n + a^n+1 +a^n+2

Answers

Answer:

$a^(n)$ (1 + a + a²)

Step-by-step explanation:

consider the rule of exponents

$a^(m)$ × $a^(n)$ = $a^((m+n))$

given $a^(n)$ + $a^(n+1)$ + $a^(n+2)$

Take out the common factor $a^(n)$

= $a^(n)$ (1 + a + a²)

forty children from an after school club went to the matinee. this is 25% of the children at the club. how many children are in the club

Answers

Number of children from an after school that went to the martinee = 40
Percentage of children from an after school that went to the martinee = 25%
Let us assume the number of children in the club = x
Then
25% * x = 40
(25x/100) = 40
x/4 = 40
x = 40 * 4
= 160
So the total number of children in the club is 160. I hope the procedure is clear enough for you to understand. you can always use this method for solving similar problems without requiring any help from outside.

25% of 40 is 10. So there are still 30 kids in the club. :)

3.25, 3.0, 2.75, 2.5, 2.25, ...What is the rule to continue this decimal number pattern?
increase by 0.5
increase by 0.25
decrease by 0.5
decrease by 0.25

Answers

3.25 - 3 = 0.25
3 - 2.75 = 0.25
2.75 - 2.5 = 0.25
2.5 - 2.25 = 0.25

Since we subtracted those numbers, it means we are decreasing.
Therefore, the answer is decrease by 0.25.

you are decreasing by 0.25 . Each time you are subtracting only .25 to each number . +
