Owen drove 9 miles total five days this week on Saturday he drove 17 miles to his grandmas house how many total miles did he drive this week

The value of A in the 4-digit number, 3A5A is 5.

The 4-digit number provided in the question has to be a multiple of 15 given the information in the question. A multiple of a number is divisible by that number. A multiple of 10 is 100 because when 100 is divided by 10 , the value gotten is 10.

A multiple of a number is the product of an integer and that number. For example, a multiple of 2 is 100. This is because 2 multiplied by 50 is equal to 100.

The multiplies of 15 either have a unit value of 5 or 0.

If A is 5, the number becomes 3555.

3555 / 15 = 237

If A is 0, the number becomes 3050

3050 / 15 = 203.33

Thus, the value of A is 5 because 3555 is divisible by 15.

Answer:

26 and 32 are the two numbers, the product is 832

Step-by-step explanation:

If a cargo van delivers only 50-pound and 80-pound packages and the total weight of the packages cannot exceed 1,500 pounds, then a system of inequalities to determine the maximum number of 80-pound packages that the van can carry per trip is x + y ≥ 20; 80x + 50y ≤ 1,500.

A system of inequalities is a term used in mathematics that is a set of two or more than two inequalities in one or more than one variable.

Consider,

the number of 80-pound packages = x

the number of 50-pound packages = y

As the van can carry a minimum of 20 packages, the sum of x and y can be given as,

x + y ≥ 20

The weight of 80-pound boxes can be given as 80x and the weight of 50-pound boxes can be given as 50x. As the total weight of the packages cannot be more than 1500 pounds,

80x + 50y ≤ 1500

If we consider x to be 19,18 or 17 and the remaining to be y, it will exceed the limit of 1500 pounds. If x is considered to be 16,

80(16) + 50 (4) = 1480

Hence, the maximum number of 80-pound packages that the van can carry per trip is 16.

The average rate of change between the given values of the variable is 21

A function can be defined as an expression or rule showing the relationship between a dependent and an independent variable.

Given the function;

h(t) = 2t^{2}[/tex] − t

For t =2

Substitute the value of t as 2 in the function, we have;

h(2) = 2 (2)² - (2)

Find the square

h(2) = 2(4) - 2

h(2) = 8 - 2

h(2) = 6

For t = 9

Substitute the value of t as 9 in the function, we have;

h(9) = 2(9)² - 9

Find the square

h(9) = 2(81) - 9

h(9) = 153

The average change = 153 - 6 = 147/ 9 -2 = 147/ 7 = 21

Thus, the average rate of change between the given values of the variable is 21

By substitution, the solution of the system of equations, 3c + 2d = 2 and d = 4, is (c , d) = (-2 , 4).

A system of linear equations is a set of two or more equations which includes common variables. To solve system of equations, we must find the value of the unknown variables used in the equations that must satisfy both equations.

There are three methods that can be used to solve system of linear equations.

1. Elimination

2. Substitution

3. Graphing

Using substitution method, given two linear equations in variables c and d,

3c + 2d = 2     (equation 1)

d = 4     (equation 2)

Since the second equation is already expressed in d in terms of a constant, substitute the second equation to the first equation.

3c + 2d = 2     (equation 1)

3c + 2(4) = 2

3c + 8 = 2

Combining all terms containing the variable c on one side and the constants on the other side of the equality, and solving for c.

3c + 8 = 2

3c = 2 - 8

3c = -6

c = -6/3

c = -2

Hence, the solution of the given system of equations is (c , d) = (-2 , 4).

The number falls between [tex]-\frac{25}{4}[/tex] and - 400 % is [tex]-\frac{43}{8}[/tex] = 5.375

first we convert fraction into decimal number

[tex]-\frac{25}{4}[/tex]  = - 6.25

and for remove percentage we divide by 100

- 400 % = - 4

from choose the option,

[tex]-\frac{43}{8}[/tex]  = 5.375

- 720 % = - 7.2

[tex]-\frac{20}{3}[/tex] = - 6.6

then, choose  [tex]-\frac{43}{8}[/tex]  

therefore, number lies between [tex]-\frac{25}{4}[/tex] and - 400 % is [tex]-\frac{43}{8}[/tex] = 5.375

A fraction is any number of the form a/b where both “a” and “b” are whole numbers and b≠0. On the other hand, a rational number is a number which is in the form of p/q where both “p” and “q” are integers and q≠0.

Thus, a fraction is written in the form of m/n, where n is not 0 and m & n are whole (or natural numbers). For example, 12/23, 10/32, 12/10, 4/21. A rational number can also be written in the form of a/b, where b is not 0 and a & b are integers. For example, 15/7, -18/13, 3/-7, -6/-12.

All fractions can be termed as rational numbers; however, all rational numbers cannot be termed as fractions. Only those rational numbers in which ‘p’ and ‘q’ are positive integers are termed as fractions. Let a/b be any fraction. Now, a and b are natural numbers. Since all natural numbers are also integers, a and b are also integers. Thus, the fraction a/b is the quotient of 2 integers such that b ≠ 0. Hence, a/b is a rational number. One of the examples in which a number is a rational number but not a fraction is:

Consider the fraction 12/-32. It is a rational number but not a fraction because its denominator (n) is not a natural number.

A fraction is expressed in the form of the ratio of whole numbers, a/b and b≠0.

A rational number is also expressed in the form of a ratio, p/q, where numerator and denominator are integers and q≠0.

The sequence 1620,540,180,60,20, . . . .. is a geometric sequence with common ratio 1/3.

To determine whether the sequence is an arithmetic or geometric one, we need to check how the consecutive terms relate to each other.

If it is an arithmetic sequence, then:

  a(n) = a(n-1) + d

where d is the common difference.

If it is a geometric sequence, then:

  a(n) = a(n-1) . r

where r is the common ratio.

The given sequence is:

    1620,540,180,60,20, . . .  .

In this sequence:

a(1) = 1620

a(2) = 540

a(3) = 180

First we check the difference between 2 consecutive terms:

a(2) - a(1) = 540 - 1620 = -1080

a(3) - a(2) = 180 - 540 = -360

Since the difference is not constant, then the sequence  is not an arithmetic one.

Now we check the ratio,

a(2) : a(1) = 540 : 1620 = 1/3

a(3) : a(2) = 180 : 540 = 1/3

and so on

Since the ratio of consecutive terms are constant, then the given sequence is a geometric sequence. Furthermore, its ratio, r = 1/3

Number systems are mathematical systems that allow computers to understand and express numbers in various ways. A number is a mathematical value that is used to count and measure items as well as execute arithmetic calculations.

Natural numbers, whole numbers, rational and irrational numbers, and so on are all types of numbers. Similarly, different number systems with differing properties exist, such as the binary number system, the octal number system, the decimal number system, and the hexadecimal number system.

Let the number calls be x where the messages will result in the exact same charge

So, Cell phone company A charges $20 per month plus $0.05 per text

message is 20 + 0.05x

And, Cell phone company B charges $10 per month plus $0.07 per text message is 10 + 0.07x

As we want the numbers to be equal, following equation is obtained

20 + 0.05x = 10 + 0.07x

Lets find x

20 + 0.05x = 10 + 0.07x

0.07x - 0.05 = 20 -10

0.02x = 10

The baseball field mark up its organic hotdogs from $2.00 to $6.50 each by 225%.

The markup on cost is defined as the amount added to the original cost of a product or service to arrive at the new selling price. It can also be a percentage of the original cost.

mark up = selling price - original price

If organic hotdogs at the grocery store cost $2.00 each and at a major league baseball game, an organic hotdog cost $6.50, then the mark up price is the difference between the two.

mark up = selling price - original price

mark up = $6.50 - $2.00

mark up = $4.50

To get the percentage of the mark up from the original price, divide the mark up price by the original selling price and multiply by 100%.

percent mark up = (mark up price/original price) x 100%

percent mark up = ($4.50/$2.00) x 100%

percent mark up = 2.25 x 100%

We are provided with that Point N is the midpoint of FG and FN = 2x and We need to find expression that  represents FG

As N is the midpoint of line segment FG than FN = NG

Also it could be written as FG = FN + NG because FG is the broken into two different line segment FN and NG because of the midpoint N

Therefore, FN = 2x which means FN= NG=2x

So, we can write an expression that could represent FG
