the price for 15 boxes of pencils is $67. The price for 34 boxes is $143. by how much does the cost increase for each additonal box of pencils purchased?

Answers

Answer 1

Answer:

$0.3

Step-by-step explanation:

Cost of one box in a set,

→ 67/15

→ 4.47 = $4.5

Cost of one box in another set,

→ 143/34

→ 4.205 = $4.2

The cost increase for each extra box,

→ 4.5 - 4.2

→ $0.3

Hence, the answer is $0.3.

Step-by-step explanation:

3 feet = 1 yard

set up a proportion

[tex]\frac{3}{4.41} = \frac{1}{x}[/tex]

The water level in a swimming pool decreases from 60 inches to 58.25 inches in one week. Assuming that the water level changes at a constant rate, how much did the water level decrease each day? O 0.25 in. O 0.35 in. O 1.25 in. 1.75 in.​

Answers

The water level decrease each day is A. 0.25 in.

How to calculate the value?

From the information, the water level in a swimming pool decreases from 60 inches to 58.25 inches in one week.

There are 7 days in a week.

Therefore, the rate if decrease per day will be:

= (60 - 58.25)/7

= 1.75 / 7

= 0.25

Therefore, the correct option is A.

A probability sampling method in which we randomly select one of the first k elements and then select every kth element thereafter is _____ sampling.

Answers

A probability sampling method in which we randomly select one of the first k elements and then select every kth element thereafter is systematic sampling.

What is systematic sampling?Systematic sampling is a statistical method used in survey methodology that involves selecting elements from an ordered sampling frame. An equiprobability method is the most common type of systematic sampling. The list is traversed in a circular fashion in this approach, with a return to the top once the end of the list is reached. Systematic sampling is a probability sampling method in which we randomly select one of the first k elements and then select every kth element after that. Using this method, each element in the population has a known and equal chance of being selected (also known as Epsem). As a result, systematic sampling is functionally equivalent to simple random sampling (SRS).

Therefore, a probability sampling method in which we randomly select one of the first k elements and then select every kth element thereafter is systematic sampling.

The Consecutive numbers are:

Consecutive numbers are those that appear consecutively after one another in the range of smallest to largest. An illustration would be the sequence of numbers 1, 2, 3, 4, 5, and so on.

Where can I find consecutive numbers?

Let x be the first of the following numbers to represent it algebraically. Following that, the numbers x + 1, x + 2, and x + 3 would be arranged in order. You must make sure that your first selection is an even number if the question requires consecutive even numbers.

According to the given information:

We can employ the expression "2n," where n is any integer, to ensure that the result is even. By using the expression "2n + 1," we can ensure an odd number.

"2n + 3" will be the following odd number:

(2n + 1)(2n + 3) is the component of the odd integers, and it equals 255:

(2n + 1)(2n + 3) = 255

4n2 + 8n + 3 = 255

4n2 + 8n - 252 = 0

n2 + 2n - 63 = 0

(n + 9)(n -7) = 0

n = -9 and n = 7

We can disregard n = -9 because we are informed that the figures must be positive.

If n = 7,

The first odd number = 2(7) + 1 = 15

The second is then 17

Determine whether the system is consistent. x1 x2 x3 = 7 x1 - x2 2x3 = 7 2x1 3x3 = 15

Answers

The given system is not consistent.

Given system of equations are:

[tex]x_1+x_2+x_3=7\\x_1-x_2+2x_3=7\\2x_1+3x_3=15[/tex]

Here the indeterminants are [tex]x_1,x_2,x_3[/tex]. A system of equations is consistent if it has at least one set of solution values for the indeterminants.

So we try to solve the above system of equations.

Subtracting the first two solutions, we get,

[tex](x_1+x_2+x_3)-(x_1-x_2+2x_3)= 0[/tex]

⇒ [tex]2x_2-x_3=0[/tex]

⇒ [tex]x_3=2x_2[/tex]

Rewriting all the three equations using this substitution,

[tex]x_1+x_2+2x_2=7\\x_1-x_2+4x_2=7\\2x_1+6x_2=15[/tex]

This implies,

[tex]x_1+3x_2=7\\x_1+3x_2=7\\2x_1+6x_2=15[/tex]

Since the first two equations are same, we need to solve the equations,

[tex]x_1+3x_2=7\\2x_1+6x_2=15[/tex]

Multiplying the first equation by 2 and then subtracting, we get,

0 = -1, which is impossible.

So the system has no solutions.

Hence the system is inconsistent.

Answers

Using proportions, it is found that Charlotte should ask for $62.5 in the budget to spend on thread.

What is a proportion?

A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct(when both increase or both decrease) or inverse proportional(when one increases and the other decreases, or vice versa), can be built to find the desired measures in the problem, or equations to find these measures.

Each uniform needs 50 buttons, and there are 100 uniforms, hence the number of buttons needed is:

50 x 100 = 5000.

Each button requires of a yard of thread, hence the number of yards needed is:

5000 x 1 = 5000 yards.

A 400-yard spool of thread is sold for $5, hence the budget needed is:
