Answer:

total marbles in the box is 600

Answer:

2/6561

Step-by-step explanation:

Geometric sequence formula : [tex]a_n=a_1(r)^n^-^1[/tex]

where an = nth term, a1 = first term , r = common ratio and n = term position

given ratio : 1/3 , first term : 2 , given this we want to find the 9th term

to do so we simply plug in what we are given into the formula

recall formula : [tex]a_n=a_1(r)^n^-^1[/tex]

define variables : a1 = 2 , r = 1/3 , n = 9

plug in values

a9 = 2(1/3)^(9-1)

subtract exponents

a9 = 2(1/3)^8

evaluate exponent

a9 = 2 (1/6561)

multiply 2 and 1/6561

a9 = 2/6561

Lines can be divided into segments by using the line segment ratios

The reason why the Safara's method works is (d) Triangles ABE and ACD can be proved to be similar

The line ratio is given as

Ratio = 9 : 4

When the line is divided by the vertical and the horizontal lines, the segments form similar triangles ACD and ABE (see attachment)

Hence, the reason why the Safara's method works is that:

Triangles ABE and ACD can be proved to be similar

Answer: 2n-7

Step-by-step explanation:

Volume of cylinder = Base Area x Height

V=πr2h

Rearrange for h

Height = Volume/Base Area

h = V/πr2

h = (6n² -13n -28)/(3n+4)

See the long division of the polynomials below, the quotient is 2n-7 which represents the height of the cylinder

Answer:

Rectangle: 112m

Trapezoid: 28m

Step-by-step explanation:

The area of the rectangle is 8*14, which is 112. The area of the trapezoid is ((base1 + base2)* height)/2. That is ((4+10)*4)/2, which is 28.

Answer:

Step-by-step explanation:

you ask for the two separate areas

The area of a trapezoid is found using the formula, A = ½ (a + b) h, where 'a' and 'b' are the bases (parallel sides) and 'h' is the height

[(14 - 2 - 2 + 4) * (12 - 8)] : 2 =

(14 * 4) : 2 = 28m² (trapezoid)

The area of a rectangle is found by multiplying the length by the width

14 * 8 =

112m² (rectangle)

Answer:

△stu could be similar to △pqr IF They have 2 angles that are the same (congruent) also known as the AA theorem. Another way would be if the triangle have a 2 side that are congruent and an angle that is congruent that is between both sides (the rule is known as the SAS theorem)! The last rule would be if all the side are congruent OR if they equal the same thing. For example if you got a triangle with 3,4,5 as sides and another one that has 6,8,10 as sides. 3/6 = 4/8 = 5/10 so that would be the SSS rule

Hope you found that helpful!!!

Step-by-step explanation:

ΔSTU ~ ΔPQR if and only if [tex]\frac{ST}{PQ} = \frac{TU}{QR} = \frac{SU}{PR}[/tex] and ∠S ≅∠P , ∠T≅∠Q and ∠U≅∠R.

" Two triangles are said to be similar if the ratio of the corresponding sides of one triangle to the other triangle are in proportion and corresponding angles are congruent."

According to the question,

ΔSTU is similar to  ΔPQR,

As per the definition of similar triangles we have,

Corresponding sides are in proportion.

ST ↔PQ

TU↔QR

SU↔PR

Therefore,

[tex]\frac{ST}{PQ} = \frac{TU}{QR} = \frac{SU}{PR}[/tex]  are in proportion.

∠S↔∠P

∠T↔∠Q

∠U↔∠R

∠S ≅∠P ,

∠T≅∠Q

∠U≅∠R.

Hence, ΔSTU ~ ΔPQR if and only if [tex]\frac{ST}{PQ} = \frac{TU}{QR} = \frac{SU}{PR}[/tex] and ∠S ≅∠P , ∠T≅∠Q and ∠U≅∠R.

The prοbability οf getting 4 green οutcοmes and 1 οrange οutcοme in 5 rοlls οf the number cube is 803/1000 οr 0.803 as a decimal.

Prοbability can be defined as ratiο οf number οf favοurable οutcοmes and tοtal number οutcοmes.

The prοbability οf rοlling a green side is 5/6, and the prοbability οf rοlling an οrange side is 1/6.

Tο find the prοbability οf getting 4 green οutcοmes and 1 οrange οutcοme in 5 rοlls, we can use the binοmial prοbability fοrmula:

P(4 green, 1 οrange) = (5 chοοse 4) * [tex](1/6)^1 * (5/6)^4[/tex]

where (5 chοοse 4) represents the number οf ways tο chοοse 4 rοlls οut οf 5 tο be green.

(5 chοοse 4) = 5! / (4! * 1!) = 5

Substituting this value intο the fοrmula:

P(4 green, 1 οrange) [tex]= 5 * (1/6)^1 * (5/6)^4[/tex]

= 5 * (1/6) * (625/1296)

= 3125/3888

= 0.803

Therefοre, the prοbability οf getting 4 green οutcοmes and 1 οrange οutcοme in 5 rοlls οf the number cube is 803/1000 οr 0.803 as a decimal.

Step-by-step explanation:

We're going to be factoring:

[tex]12 {x}^{4} + 27 {x}^{3} + 6 {x}^{2} [/tex]

We know that the GCF between 12, 27, and 6 is 3.

We also know that the GCF of x^4, x^3, and x^2 is x^2.

When factoring:

[tex]3{x}^{2} (4 {x}^{2} + 9x + 2)[/tex]

We know 3x^2 is the correct option since the polynomial is factored completely.

Answer:

[tex]3x^2[/tex]

Step-by-step explanation:

[tex]12x^4 + 27x^3 + 6x^2[/tex]

The coefficients of the variables are 12, 27 and 6.  The greatest common factor (GCF) of these numbers is 3.

[tex]\implies 3(4x^4 +9x^3 + 2x^2)[/tex]

From inspection, the GCF of the variables is [tex]x^2[/tex]

[tex]\implies 3x^2(4x^2+9x + 2)[/tex]

Therefore, the GCF of the terms in the polynomial is [tex]3x^2[/tex]

Answer:

5400

Step-by-step explanation:

Let x represent the cost of a chair and y represent the cost of a table. We can use this to set up a system of equations:

7x=2y

6x+5y=10575

We can solve this system using substitution.

Start by rewriting the first equation in terms of x.

[tex]7x=2y\\\text{Divide both sides by 7}\\x=\frac{2}{7}y[/tex]

Substitute this into the second equation:

[tex]6(\frac{2}{7}y)+5y=10575\\\frac{12}{7}y+5y+10575\\\frac{12}{7}y+\frac{35}{7}y=10575\\\frac{47}{7}y=10575[/tex]

Multiply both sides by 7

[tex]47y=74025[/tex]

Divide both sides by 47

[tex]y=1575[/tex]

This means...

[tex]7x=2(1575)\\7x=3150[/tex]

Divide both sides by 7

[tex]x=450[/tex]

One chair costs 450. Now, multiply this number by 12 to find the cost of 12 chairs.

[tex]450*12=5400[/tex]

12 chairs cost 5400.

Answer: B: 19.5

Step-by-step explanation:

This data set is an even data set meaning that you're going to have to add and divide, so you put your data set in ascending order (highest # to lowest #) so 12,12,15,24,31,38 its an even data set so you're going to put them in groups (remember your finding the median, the middle numbers) so you have 12,12 (one group) and 31,38 (another group) (basically make it even!!) so now you're left with the middle numbers, you have to add them and then divide them by 2 so (15+24) ÷2 and you get your answer !!
