Answer:

Step-by-step explanation:

The entire question is:

A map shows the town where Niko lives. The actual distance from​ Niko's house to his school is 3 miles and measures​ one-half inch on the map. The actual distance from​ Niko's school to the library is 4 miles. How long is this distance on the​ map?

To solve this problem, we can apply the rule of three, if 3 miles are one-half inch on the map, how long would be on the map for 4 miles.

[tex]x=4miles\frac{\frac{1}{2}in }{3miles}=4\frac{1}{6}in=\frac{2}{3}in[/tex]

Therefore, 4 miles would be 2-thirds inch on the map.

The actual distance of 4 miles would be 2-thirds inch on the map.

If 3 miles is shown by one-half inch on the map, then to find the length on the map for 4 miles, you can set up a proportion:

(3 miles) / (1/2 inch) = (4 miles) / x

Now, cross-multiply:

3 * x = 4 miles * (1/2 inch)

3x = 2 miles * inch

So , divide both sides by 3 to find the length on the map (x):

x = (2 miles * inch) / 3

x = 2/3 inch

So, the correct length on the map for 4 miles is indeed 2/3 inch.

iman has 48  cards and mateo has 80 cards

To find out how many sports cards Iman and Mateo each have, we can set up an algebraic equation based on the total number of cards and the packs they have. After solving the equation, we find that Iman has 48 sports cards, and Mateo has 80 sports cards.

The student's question pertains to a problem involving arithmetic and algebra. Iman and Mateo have a total of 128 sports cards combined. The question asks us to find out how many sports cards each child has. Let's call the number of cards that each pack contains 'x'. Therefore, Iman's cards can be represented as 6x and Mateo's cards as 10x. According to the information, 6x + 10x equals 128.

Combining the terms gives us 16x = 128. We can find 'x' by dividing both sides of the equation by 16, which gives us x = 8. Therefore, Iman has 6 packs times 8 cards per pack, which results in 48 cards, and Mateo has 10 packs times 8 cards per pack, adding up to 80 cards.

Iman has 48 sports cards and Mateo has 80 sports cards.

To solve the problem, an algebraic equation is set using the given conditions. After solving it, it's established that Nate has 28 one-dollar bills and 21 five-dollar bills.

Let's solve the problem in two steps. First, we already know the total sum of money Nate has, which is $267, and the value of his eleven $10 bills, which is $110. So, we subtract $110 from $267, leaving $157 to be divided among the $5 and $1 bills.

Next, we assign variables to the unknowns. Let's call the no of $1 bills 'x' and no of $5 bills ''x-7'. A $5 statement is worth five $1 bills so that we can rewrite 'x-7' as '5(x-7)'. Setting up the equation 5(x - 7) + x = 157 and solving for x gives us 28.

The problem-solving strategy here is using a system of equations to solve a money problem. So Nate has 28 one-dollar bills and 21 five-dollar bills (28-7).

Hey there!!

Equation given :

... 78 = -2 ( m + 3 ) + m

... 78 = -2m - 6 + m

... 78 = -m - 6

... 78 + 6 = -m

... 84 = -m

... m = -84

Hope my answer helps!!

Hello there!

The answer should be the third option C.

[tex]78 = -2(m + 3) + m[/tex]

First you had to simplify from both sides of the equations.

[tex]78=-2(m+3)+m[/tex]

[tex]78=(-2)(m)+(-2)(3)+m[/tex]

[tex]78=-2m+-6+m[/tex]

[tex]78=(-2m+m)+(-6)[/tex]

[tex]78=-m+-6[/tex]

[tex]78=-m-6[/tex]

Then you can flip by the equation.

[tex]-m-6=78[/tex]

Add by 6 from both sides.

[tex]-m-6+6=78+6[/tex]

[tex]-m=84[/tex]

Divide by -1 from both sides.

[tex]\frac{-m}{-1}=\frac{84}{-1}[/tex]

Simplify should be the correct answer.

[tex]m=-84[/tex]

Answer: The smallest possible number is 136.

Step-by-step explanation:

1. You need to find the Least common multiple (LCM), which is the smallest of the common multiples of 17 and 8.

2. You can descompose 17 and 8 into primes factors. Then, you obtain:

[tex]17=17[/tex]

[tex]8=(2)(2)(2)=2^{3}[/tex]

3. Now, you must choose commons and no commons with the greatest exponent and multiply them. Therefore the result is:

[tex](17)(2^{3})=136[/tex]

[tex]LCM=136[/tex]

The smallest possible number that is divisible by both 17 and 8 is 136.

To find the smallest possible number that is divisible by both 17 and 8, we need to find their common multiple. The common multiples of 17 and 8 are found by multiplying them together and continuing until a common multiple is obtained. The smallest common multiple of 17 and 8 is 136.

The proposed definition of a regular polygon as having all angles of the same measure is incomplete because it omits the criterion of all sides being equilateral. Hence, some irregular polygons could fit this definition, making it not entirely valid.

The definition of a regular polygon as “a polygon with all angles the same measure” is not completely valid.

A more precise definition of a regular polygon is a polygon that is both equiangular (all angles have the same measure) and equilateral (all sides have the same length).

While all regular polygons have angles of equal measure, the definition provided is incomplete as it does not include the requirement that all sides must also be of the same length.

For example, consider an isosceles triangle (a triangle with two sides of equal length).

This triangle has two angles of the same measure and one that is different. B

ased on the provided definition, one might incorrectly classify this as a regular polygon, even though it is not.

Thus, the correct answer is C. No, because some polygons that are irregular fit this definition.

Final answer:

The definition for a regular polygon as 'a polygon with all angles the same measure' is not fully accurate because it omits the requirement for all sides to be of equal length.

The correct answer to the question is C. No, because some polygons that are irregular fit this definition.

Explanation:

The definition of a regular polygon that states it is “a polygon with all angles the same measure” is not entirely valid. While it's true that a regular polygon does have equal angles, the definition is incomplete without the inclusion of another important characteristic: all sides must be of equal length.

Therefore, the correct answer to the question is C. No, because some polygons that are irregular fit this definition.

An irregular polygon can also have equal angles but different side lengths, so the definition given would incorrectly include some irregular polygons.

When thinking about a regular polygon, it's essential to consider both equal angles and equal side lengths, just as when thinking about a triangle, it includes a three-sided figure lying on a plane with three angles adding up to 180 degrees.

x is equal to 27.

In order to find the value of x, you have to use the average formula and solve for the missing variable. The mean formula is all of the numbers added together divided by the number of inputs.

(inputs added)/(number of inputs) = Average

(2 + 7 + x)/3 = 12 ----> Multiply by 3

9 + x = 36 ----> Subtract 9

x = 27

To find the value of x when the average of 2, 7, and x is 12, you set up and solve the equation (2 + 7 + x) / 3 = 12. After simplifying, you will find that x equals 27.

The question asks us to find the value of x when the average (arithmetic mean) of the numbers 2, 7, and x is 12. To find the value of x, we use the formula for the arithmetic mean, which for three numbers is (number1 + number2 + number3) / 3 = average. So, we set up the equation: (2 + 7 + x) / 3 = 12.

First, we multiply both sides of the equation by 3 to eliminate the fraction:
2 + 7 + x = 36. Next, we add the known values on the left side: 9 + x = 36. Finally, to find x, we subtract 9 from both sides of the equation: x = 36 - 9, which simplifies to x = 27. Therefore, the value of x is 27.

Given points (5,102) (4,74) and (-2,-10)

We frame 3 equations using the given points

[tex]y=ax^2+bx+c[/tex]

Plug in (5,102)

[tex]102=a(5)^2+b(5)+c[/tex]

102 = 25a +5b + c -------> first equation

Plug in (4,74)

[tex]74=a(4)^2+b(4)+c[/tex]

74 = 16a +4b + c----> second equation

Plug in  (-2,-10)

[tex]-10=a(-2)^2+b(-2)+c[/tex]

-10 = 4a -2b + c -----> third equation

Now we use the three equation and solve for a,b,c

Use first and second equation and subtract it

102 = 25a +5b + c

-74 = -16a -4b - c

----------------------------------

28 = 9a + b  --------------> fourth equation

Subtract third equation from first equation

102 = 25a +5b + c

10  = -4a +2b - c

----------------------------------

112 = 21a + 7b --------------> fifth equation

Use fourth and fifth equation

28 = 9a + b

112 = 21a + 7b

Multiply the fourth equation by -7

-196= -63a -7b

112 = 21a + 7b

-----------------------

-84 = -42a

Divide by -42 on both sides

a= 2

Plug in the value of a=2 in fourth equation

28 = 9a + b

28 = 9(2) + b

28 = 18 + b ( subtract 18 from both sides)

b = 10

Plug in the values in third equation and find out c

-10 = 4a -2b + c

-10= 4(2) -2(10)+c

-10 = -12 + c

c= 2

We got a=2, b=10  and c=2

So equation becomes [tex]y=2x^2+10x+2[/tex]

Melissa has completed 85% of the bike course by riding 51 out of 60 miles. This was calculated by dividing the distance ridden by the total distance and multiplying by 100.

To find out what percentage of the bike course Melissa has ridden, we need to divide the distance she has ridden by the total distance of the course and then multiply by 100 to get the percentage. Melissa has ridden 51 miles of the 60 miles long course. Therefore, the percentage of the course she has ridden is calculated as follows:

When we perform this calculation, we get:

(51 / 60) * 100 = 85%

So, Melissa has ridden 85% of the bike course.
