Step-by-step explanation:

3.14*3*2*7=197.92

Answer:

197.92 cu cm  to the nearest hundredth

Step-by-step explanation:

Volume = area of the base time the height.

Your base is a circle, so A = [tex]\pi r^{2}[/tex] = [tex]\pi 3^{2}[/tex] = 9π

Vol = 9π(7) = 63π ≅ 197.92 cu cm  to the nearest hundredth

Answer:

126 dollars

Step-by-step explanation:

(i'm gonna be doing my work here, dont mind me LOL)

okay, so they sold 24 packs in 4 days. divide 24 by 4 and you get 6. multiply 6 by 3 and you get 18.

now, multiply 18 by seven and you get 126.

bam!! the dance team could earn 126$ in 7 days ^__^ hope you get an A!

Answer:

$126

Step-by-step explanation:

Let x = packs sold in 7 days

Set up a proportion.   days/days = packs/packs

4/7 = 24/x

4x = 24(7)  = 42 packs sold in 7 days

At $3/pack, the amount earned in 7 days =  3(42) = $126

Answer:

$19:50

Step-by-step explanation:

Write a system of equations to represent the problem. Let x represent the cost of a binder, and let y represent the cost of a notebook.

Grace buys 4 binders and 7 notebooks for $26.50 total, so the equation 4x+7y=26.50 represents how much Grace spends.

Grace's friend buys 3 binders and 6 notebooks for $21.00 total, so the equation 3x+6y=21 represents how much her friend spends.

You can use this system of equations to find how much money Grace and her friend spend on notebooks:

4x+7y=26.50

3x+6y=21

Next, find how much Grace and her friend spent on notebooks. Start by finding the cost of one notebook. Use elimination to solve for y. .

3(4x+7y)=3(26.50)  

–

12x+21y = 79.50

–

4(3x+6y)=

–

4(21)  

–

12x–24y =  

–

84

–

3y =  

–

4.50

y = 1.50

Each notebook costs $1.50. Grace and her friend buy a total of 13 notebooks, so multiply to find how much money they spend on notebooks.

13$1.50=$19.50

Grace and her friend spend $19.50 total on notebooks.

The system of equations y =−7x + 8  and y = −7x − 8 ​ have no solution

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

y =−7x + 8

y = −7x − 8 ​

Subtracting the two equations

We have

y - y = -7x + 7x + 8 + 8

When the like terms are evaluated, we have

0 = 16

The above equation is false

This means that the equation has no solution

Step-by-step explanation:

The end behavior of a function f describes the behavior of the graph of the function at the "ends" of the x-axis. In other words, the end behavior of a function describes the trend of the graph if we look to the right end of the x-axis (as x approaches +∞ ) and to the left end of the x-axis (as x approaches −∞ ).

Step-by-step explanation:

The calculator solves the triangle specified by three of its properties. Each triangle has six main characteristics: three sides a, b, c, and three angles (α, β, γ). The classic trigonometry problem is to specify three of these six characteristics and find the other three. Of course, our calculator solves triangles from any combinations of main and derived properties such as area, perimeter, heights, medians, etc. Usually by the length of three sides (SSS) or side-angle-side or angle-side-angle.

How does this triangle calculator solve a triangle?

The calculation of the general triangle has two phases:

expert phase - which is different for different tasks. From the entered data, the calculator tries to calculate the sizes of three sides of the triangle. He gradually applies the knowledge base to the entered data, which is represented in particular by the relationships between individual parameters of the triangle. These are successively applied and combined, and the parameters of the triangle calculate. Calculator iterate until the triangle has calculated all three sides.

For example, from the given area of the triangle and the corresponding side, the appropriate height is calculated. From the known height and angle, the adjacent side, etc., can be calculated. They use knowledge, e.g., formulas (relations) Pythagorean theorem, Sine theorem, Cosine theorem, Heron's formula, solving equations and systems of equations.

The second stage is the calculation of the properties of the triangle from the known lengths of its three sides.

Examples of how to enter a triangle:

All the sides of the triangle are different and do not satisfy Pythagoras' theorem. Then the triangle is a scalene triangle.

The polygonal shape of a triangle has a number of sides and three independent variables. Angles in the triangle add up to 180 °.

The dimensions of the triangle are 15, 16, and 21.

Check whether it satisfies the Pythagoras theorem or not. Then we have

H² = P² + B²

21² = 16² + 15²

441 = 256 + 225

441 ≠ 481

Every one of the sides of the triangle is unique and doesn't fulfill Pythagoras' hypothesis. Then the triangle is a scalene triangle.

The 3rd term of 7th row of the Pascals triangle is 21.

We have a Pascal's triangle.

We have to determine the 3rd term of 7th row of this triangle.

A pascal's triangle is an arrangement of numbers in a triangular array such that the numbers at the end of each row are 1 and the remaining numbers are the sum of the nearest two numbers in the above row. The pascals triangle is shown below -

[tex]\begin{tabular}{rccccccccc}$n=0$:& & & & & 1\\\noalign{\smallskip\smallskip}$n=1$:& & & & 1 & & 1\\\noalign{\smallskip\smallskip}$n=2$:& & & 1 & & 2 & & 1\\\noalign{\smallskip\smallskip}$n=3$:& & 1 & & 3 & & 3 & & 1\\\noalign{\smallskip\smallskip}$n=4$:& 1 & & 4 & & 6 & & 4 & & 1\\\noalign{\smallskip\smallskip}\end{tabular}[/tex]

If we have to find the element or term at position - m in row number - n, than the element will be -

[n] C [m-1] = [n-1] C [m-2] + [n-1] C [m-1]

According to the question, we have to find the 3rd term of 7th row of this triangle. It can be found out using the formula -

[n] C [m-1] = [n-1] C [m-2] + [n-1] C [m-1]

We have - n = 7 and m = 3

[7] C [2] = [6] C [1] + [6] C [2]

[tex]$\frac{7!}{(7-2)!2!} = \frac{6!}{(6-1)!1!} + \frac{6!}{(6-2)!2!} = 6 + 15 = 21[/tex]

Hence, the 3rd term of 7th row of the Pascals triangle is 21.
