Suppose that 12 inches of wire cost 48 cents at the same rate how many inches of wire can be bought for 28 cents

The total number of students going on a trip is 375 students.

Given that,

The entire third through fifth graders are taking a field trip to Coney Island. There are 125 pupils each grade. The cafeteria should provide lunches.

We have to find how many students will be travelling on the trip.

So,

In Grade 3 we have 125 students.

In Grade 4 we have 125 students.

In Grade 5 we have 125 students.

So,

Total number of students going on trip = Number of students in Grade 3 + Number of students in Grade 4 + Number of students in Grade 5

= 125 + 125 + 125 = 375.

Therefore, The total number of students going on a trip is 375 students.

Answer:

18:360 is the correct answer

The solution to the equation given as 2x + 4y = 6x − y has the ordered pair of (3, 4)

From the question, we have the following equation that can be used in our computation:

2x+4y=6x−y

Solving further, we need to collect the like terms

So, the equation becomes

2x - 6x = -4y - y

Next, we evaluate the like terms in the above equation

So, we have the following representation

-4x = -3y

Divide both sides by -3

The equation becomes

x = 3/4y

At this point, we assume any value for y and then solve for x

Assume that the value of y is 4

So, we have the following representation

x = 3/4 * 4

Evaluate the products

x = 3

So, we have

x = 3 and y = 4

Express as ordered pairs

(x, y) = (3, 4)

Hence, the ordered pair of the solution is (3, 4)

If Sebastian filled 10 gallons of gas, the total amount he spent at the gas station was C. $40.50.

Using the mathematical operations of multiplication and addition, we can compute the total amount that Sebastian spent at the gas station.

We first determine the total cost of gas that Sebastian bought by multiplying the unit cost by the quantity.

Secondly, we add the above total cost to the total cost of other items he bought at the station to arrive at the total amount spent.

The cost of gas per gallon = $2.91

The number of gallons of gas bought = 10

The total cost of gas = $29.10 ($2.91 x 10)

The total cost of granola bars and tissues = $11.40

The total amount spent = $40.50 ($29.10 + $11.40)

Thus, mathematically, Sebastian spent C. $40.50 at the gas station.

12 and 30 are the two numbers are greater than 6 with HCF  6 and LCM  60.

What is Highest common factor and Least Common Multiple?

Least Common Multiple is the entire name of LCM in mathematics, whereas Highest Common Factor is the full name of HCF. When two or more numbers are given, the HCF identifies the largest factor present, while the LCM defines the least number that is exactly divisible by two or more numbers.

Assume that the two numbers with HCF of 6 are 6a and 6b, where a and b are co-prime and a, b > 1.

HCF x LCM = Product of the numbers.

6 x 60 = 6a x 6b

10 = a x b

10 can be written as, 1 x 10 and 2 x 5.

But a and b > 1.

So, 10 = 2 x 5

a = 2, b = 5

Therefore, the two numbers are,

6a = 6(2) = 12 and

6b = 6(5) = 30

Hence, the two numbers with HCF  6 and LCM  60 are 12 and 30.

Answer:

ln A / ln 2

Step-by-step explanation:

Using the change of base rule: ln A / ln 2

⇒ Supplementary angles are angles that add up to 180°

⇒ ∠1+∠2=180°(angles on a straight line)

∠2=∠4( Corresponding angles are equal m||n)

⇒*NOTE THE FOLLOWING STATEMENT IS TO MAKE YOU UNDERSTAND,IT MUST NOT BE INCLUDED IN YOUR ANSWERBOOK)

If ∠2=∠4

in the place of ∠2 in the equation ∠1+∠2=180° we can substitute ∠4 since the two angles (∠2 and ∠4) are equal by corresponding angles

______________________________________________________

⇒You may include this step now as you now know how ∠4 came up.

∴∠1+(∠4)=180°

∠1+∠4=180°

Now from the above equation we can see that ∠1 and ∠4 are supplementary angles as they both add up to 180°

After factorization we get the two terms ( w - 3 ) ( w + 2 )

And the values of  A and B as 3 and 2 respectively .

That is A = 3 and B = 2.

The given expression is w² - w - 6.

This question can be calculated easily by middle term split

First step is to multiply the first and the last term

which will give us - 6

thus now we have to look for two number which when either added or subtracted will give us - 1

Thus we can write it as :

w² - 3 w + 2 w - 6

Now take the terms which are common

and we will get

w ( w - 3 ) + 2 ( w - 3 )

( w - 3 ) ( w + 2 )

Thus if we compare it with (w - A) (w + B)

we will get the values of A and B as

3 and 2 respectively .

That is A = 3 and B = 2

The values that match the various trigonometric identity are;

1) sin²/₅π cos π/₁₀ + cos²/₅π sin π/₁₀ = 1

2) cos 13 cos 47 + sin 13 sin 47 = 0.5

3) sin²/₅π cos ⁸/₅π + cos²/₅π sin ⁸/₅π = 0

Trigonometric identities are defined as the equations that involves the trigonometric functions that are true for every value of the variables involved.

1) We know that the trigonometric identity sin(A + B) is expressed as;

sin(A + B) = sinAcosB + cosAsinB

We are given;

sin²/₅π cos π/₁₀ + cos²/₅π sin π/₁₀

Applying the trigonometric identity above, gives us;

sin(²/₅π + π/₁₀)

= sin(5π/10)

= sin(π/2)

= 1

2) We know that the trigonometric identity sin(A + B) is expressed as;

cos(A + B) = cosAcosB − sinAsinB.

We are given;

cos 13 cos 47 + sin 13 sin 47

Applying the trigonometric identity above, gives us;

cos(13 + 47)

Answer: There is no solution

Step-by-step explanation:

The formatting of the question isn't clear, but I'll still explore both possibilities. If the square root is only applied to x, we can solve for the variable by adding 4 to both sides and then squaring both sides, which would give us 4. Since that is not an answer choice, it means the square root applies to x-4. With this problem, we square both sides right away. That gives us x=0, but plug 0 back into the original equation. Doing so gives us the square root of -4, which is not possible with real numbers, only with imaginary numbers.

The measures of the remaining three angles of the decagon are 40, 50 and 130 degrees.

A decagon simony means a polygon with 10 sides. In a regular decagon, the interior angles add up to 1440 degrees, and the exterior angles add up to 360 degrees.

Complementary angles sum up to 90 degrees while supplementary angles sum up to 180 degrees.

Therefore,

1440 - 1220 = 220

Let the angles be a, b and c.

Therefore,

a + b + c  =220

a + b = 90

b + c = 180

Hence,

a = 220 - 180

a = 40°

b = 90 - 40

b = 50°

c = 180 - 50

c = 130°

The angles are 40°, 50° and 130°.

The x-intercept of the table of values is 12 or (12, 0).

To find the x-intercept of a table that represents a linear relationship between x and y, first write the equation that models the table.

To write the equation, first find the slope (m) using two pairs of values, say, (22, 36) and (27, 54)

Slope (m) = (54 - 36)/(27 - 22)

Slope (m) = 18/5

Write the equation that represents the table of values by substituting (a, b) = (22, 36) and m = 18/5 into y - b = m(x - a):

y - 36 = 18/5(x - 22)

To find the x-intercept, substitute y = 0 into the equation, y - 36 = 18/5(x - 22) to find the value of x:

0 - 36 = 18/5(x - 22)

-36 = 18/5(x - 22)

5(-36) = 18(x - 22)

-180 = 18(x - 22)

-180/18 = x - 22

-10 = x - 22

-10 + 22 = x

x = 12
