The total value of the coins in the jar is A = $ 0.55

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

Substituting the values in the equation , we get

The number of quarters = 1

So , the value of quarters = $ 0.25

The number of cents = 2

So , the value of cents = $ 0.20

The number of nickels = 2

So , the value of nickels = $ 10

And , the equation will be

A = value of quarters + value of cents + value of nickels

On simplifying , we get

A = 0.25 + 0.20 + 0.10

A = $ 0.55

Therefore , the value of the coins is A = $ 0.55

Hence , the equation is A = $ 0.55

Answer:

Ans = appx 10.439 units

Step-by-step explanation:

This answer will vary depending on the starting latitude of the ship due to earth not being flat, despite suddenly popular opinions.

So if we used a flat cartesian space ignoring the curvature of the earth we could have a fixed constant answer to this question. Lets do it that way.

Just to clarify: NO the earth is not flat.

Another assumption of this question is the difference between compass north and true north, which we have to throw out for the same reasons.

Real world answers to this question would not be as simple… #imjustsaying

Ok so first travel northeast, lets call that a bearing of 45 degrees directly northeast to also squash any variations there… then a bearing of 250 degrees which ill assume is not a relative bearing (LOTS OF ASSUMPTIONS GOING ON HERE) which is sortof in the west-southwest direction.

The angle at the turn goes from 45 to 250. reversing the 45 shows our angle to be between 250 and 180+45=225 so the angle is 25 degrees with one leg being 20 units (kilometers) long and the other leg being 12 units long. How many units apart are the two points that are connected to that angle?

(12sin(25))^2+(20–12cos(25))^2 = x^2

Enjoy calculating. Make sure that 25 is in degrees and not in radians.

Answer:

45 km^2 (C)

Step-by-step explanation:

Isolate the smaller square -

We only need two side lengths, take 3km and 3km.

3×3 = 9km^2, that's the area of the smaller square.

Isolate the larger square -

Take 6km and the other 6km

6×6 = 36km^2

Add the square's areas together to get the whole area -

36 + 9 = 45km^2

All you need to do to solve these problems is to isolate the shapes and find their area's, and finally add them together.

Answer:

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

Step-by-step explanation:

In order to get y by itself, we need to pull y out of 1 and m on the right side.

b = y(1 - m) since y(1 - m) is the same as y - my.

Once we have pulled y out of 1 and m, we can divide both sides by 1 - m

[tex]\frac{b}{1 - m}[/tex] = [tex]\frac{y(1 - m)}{1 - m}[/tex]

We can cancel out the 1 - m on the right side since (1 - m) / (1 - m) = 1

Finally we get our answer:

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

This is the same as y = [tex]\frac{b}{1-m}[/tex]

The method to summarize the data will be mean

The mean of the laps of swim team is 84.1 laps

What is Mean?

The mean value in a set of numbers is the middle value, calculated by dividing the total of all the values by the number of values.

Mean = Sum of Values / Number of Values

Given data ,

Let the data be represented by the set A

Let the mean of the data set be M

The value of set A = { 77 , 79 , 80 , 82 , 84 , 85 , 86 , 87 , 90 , 91 }

The total number of data elements in the set = 10

Now , since all the data elements are distributed normally and does have a central point

So , it follows normal distribution

Therefore , the mean of the data will be

Mean M = Sum of Values / Number of Values

Mean = ( 77 + 79 + 80 + 82 + 84 + 85 + 86 + 87 + 90 + 91 ) / 10

Mean = 841 / 10

Mean M = 84.1 laps

Therefore , the value of M is 84.1

Hence , The method to summarize the data will be mean

The mean of the laps of swim team is 84.1 laps

Answer:

Answer:

No.

Step-by-step explanation:

2(x-3) + 1  = 2x - 6 + 1 = 2x - 5

2x + 6   ≠   2x -5, so no, they aren't equivalent.

The expression 2(x - 3) + 1 and 2x + 6 are not Equivalent.

Equivalent expressions are expressions that perform the same function notwithstanding their appearance. If two algebraic expressions are equivalent, they have the same value when the same value(s) for the variable are used (s).

We have two expressions to compare 2(x- 3) + 1 and 2x +6 .

Now, simplifying the first expression as

= 2(x -3) + 1

= 2x - 6 +1

= 2x - 5

and, the second expression is 2x + 6.

Thus, both of expression are not Equivalent.

Answer:

109440

Step-by-step explanation:

1750 boxes of water bottles with 48 bottles of water each: 1750 x 48 = 84000

plus the other 530 boxes at the warehouse which alone are: 530 x 48 = 25440

adding up 84000 + 25440 = 109440

The total number of bottles of water in the warehouse will be 27,190.

The analysis of mathematical representations is algebra, and the handling of those symbols is logic.

A warehouse has 1,750 boxes of water bottles.

A truck unloaded another 530 boxes at the warehouse.

Each box holds 48 bottles of water.

Then the number of bottles that were unloaded by truck will be

⇒ 530 x 48

⇒ 25,440

Then the total number of bottles of water in the warehouse will be

⇒ 25,440 + 1,750

⇒ 27,190

The total number of bottles of water in the warehouse will be 27,190.
