Answer:

No

Step-by-step explanation:

You can if you want, but there is a total of 6 on the dice. And there are 3 odds. Each odd you role you gain 10 cents, but each time a student roles a even they also get 10 cents. So you will get paid and in a game of chance and gambling. You won't gain anything if ALL of the students are together and going against you. Its like 1 vs 25 and you would have to pay a lot of students at one time to play this game. So logically no, because you won't gain money. But also you could if you always get odds, but again. That's a 3/6 or 1/2 each time you role to get a odd number.

Hope that helped, or even made sense xD

The value of x in the similar triangle is 6 units.

Two triangles are said to be similar if their corresponding angles are congruent and the corresponding sides are in proportion .

Therefore, let's use the similarity ratio to find the value of x in the similar triangle as follows:

Hence,

5 / 40 = x / 48

48 × 5 = 40x

240 = 40x

divide both sides by 40

x = 240 / 40

x = 6

Therefore,

x = 6

Answer:

4.32m²

Step-by-step explanation:

Width · Length

3.6 · 1.2 = 4.32

Answer:4.32 m

Step-by-step explanation:When trying to find the area of something with length and width you multiply them both to find your answer. (1.2 x 3.6=4.32) or you can always multiply 12 times 36 and move the decimal to where it belongs.

Answer:

C

Step-by-step explanation:

For these types of problems, its important that we focus on the base as well as the lengths of the base and any other given lengths.

Here, the net has a base that forms a square with side lengths of 8mm.

So automatically, we can eliminate choices a and d as both have a base that is a triangle rather than a square.

We've also noticed that the base has a length of 8mm

If we look at B and C closely, we can tell that B has base lengths of 10mm while C has base lengths of 8mm.

So C is the correct answer choice.

Answer:

B and C

Step-by-step explanation:

Minimum and Maximum points occur when the gradient of the function is equal to 0. Graphically this looks like a bend such that the function dips from decreasing to increasing (the gradient goes form being negative to positive) and vice versa.

A minimum point occurs where all the nearby values are higher than that of the point in question.

A maximum point occurs where all the nearby points are lower than the point in question.

By looking at the graph, there is a maximum point around (4.5, 1.5) which is consistent with B but not A (since A talks about a minimum point)

By looking at the graph, there is a minimum point around (0.5, 1.5) which is consistent with C.

\(Answer: y =\dfrac{1}{2}(x +2)^{2}+\)Answer:

Step-by-step explanation:

Vertex form of quadratic function: y =a(x -h)² + k

Where (h,k) is the vertex

vertex (-2 , 6)

y = a(x -[-2])² + 6

y = a(x + 2)² + 6

This is passing through (-4,8)

8 = a(-4 + 2)² + 6

8 = a(-2)²+ 6

8  = 4a  +6

8 - 6 = 4a

4a = 2

a = 2/4

a = 1/2

Answer:

x = 18.64

Step-by-step explanation:

use tan:

⇒ tan = \(\frac{opposite}{adjacent}\)

⇒ tan 46 = \(\frac{18}{x}\)

tan of 46 is 1.0355

⇒ 1.0356 = \(\frac{18}{x}\)

multiply 18 on both sides

⇒ 1.0355 x 18 = \(\frac{18}{x}\) x 18

⇒ 18.64 = x

Answer:

k = 79%

Step-by-step explanation:

Jar A - 45% acid and 55% water - "a" liters

Jar B - 48% acid and 52% water - "b" liters

Jar C - k% acid and (100% - k%) water - "c" liters

0,45 . 4 = 1,8 l acid jar A

0,48 . 5 = 2,4 l acid jar B

2/3 + 4 = a ----> a = 14/3 liters

1/3 + 5 = b -----> b = 16/3 liters

14/3 * 50% = 14/6 = 7/3 acid jar A = 2,33 l acid jar A

16/3 * 50% = 16/6 = 8/3 acid jar B = 2,66 l acid jar B

2,33 - 1,8 =  0,53 add in jar A

2,66 - 2,4 = 0,26 add in jar B

0,53 + 0,26 = 0,79 liters acid jar C

1 - 0,79 = 0,21 liters water jar C

(0,79/1) * 100% = 79% acid in jar C

So: k% acid is 79%

The circle with a 7 feet radius cut into 6 equal sectors, indicates, using 22/7 approximation for pi, that the area of 2 of the pieces is 51 and one third square feet. The correct option is option C.

C. 51 and one third square feet

A sector of a circle is a pie shaped part of a circle that is bounded by an arc and two radii of the circle.

The specified radius of the circle, r = 7 feet

The number of pieces to which the circle is cut into = 6 equal pieces (sectors)

The area of 2 of the pieces, using 22/7 as an approximation for π are found as follows;

Area of a circle, A = π × The square of the radius

Therefore; A = π × r²

A = (22/7) × 7² = 154

The area of the circle is about A = 154 square feet

The area of one of the pieces into which the circle is cut is therefore;

Area of a piece = A/6

Area of one piece = (154 square feet)/6 = 25 and two thirds square feet

The area of 2 of the pieces = 2 × (A/6) = A/3

Therefore, the area of two of the pieces = (154 square feet)/3 = 51 1/3

The area of 2 of the pieces = \(51\frac{1}{3}\) square feet

Option C is correct

C. 51 and one third square feet

Answer: B

Step-by-step explanation:

Substitution method

solve the equation for Y by putting the variable on the left. -3 = y - 2x would become y = 2x - 3

Plug Y into the top equation. 2(2x - 3) + 6 =4x

4x - 6 + 6 = 4x

Combine like terms

4x - 0 = 4x

4x = 4x

The value of the trigonometric equation -tan ( 56 )° = -1.483

Trigonometry is the study of the relationships between the angles and the lengths of the sides of triangles

The six trigonometric functions are sin , cos , tan , cosec , sec and cot

Let the angle be θ , such that

sin θ = opposite / hypotenuse

cos θ = adjacent / hypotenuse

tan θ = opposite / adjacent

tan θ = sin θ / cos θ

cosec θ = 1/sin θ

sec θ = 1/cos θ

cot θ = 1/tan θ

Given data ,

Let the trigonometric relation be represented as A

Now , the equation will be

A = -tan ( x )°

Now , when the value of x = 56

On simplifying , we get

The value of -tan ( 56 )° = P

And , -tan ( 56 )° = - ( 1.48256 )

-tan ( 56 )° = -1.483

Hence , the measure of the trigonometric equation is -tan ( 56 )° = -1.483

The system that has linear inequalities has the point (3, -2) in its solution set is y > -3; y ≥ 2/3x - 4.

We know that

If a ordered pair is a solution of the system of inequalities, then the ordered pair must satisfy both inequalities (makes true both inequalities)

In option B, we have

y > -3 ----> inequality A

y ≥ 2/3x - 4 ----> inequality B

In both inequality, change the values of x and y at the point (3, -2) and then compare the outcomes.

Inequality A

y > -3 ----> is true

Inequality B

y ≥ 2/3x - 4 ----> is true

Therefore

The ordered pair is a solution of the system B

As a result, the point (3, -2) in the solution set of the system with linear inequalities is y > -3; y 2/3x - 4.

We are to simplify:

(2x + 3)2 - 4(2x + 3) - 12 = 0

(2x + 3) . 2 -4(2x + 3) -12 = 0

Let's add similar elements:

2(2x + 3) - 4(2x + 3) = -2(2x + 3)

Add 12 to both sides

-2(2x + 3)- - 12 + 12 = 0 + 12

let's simplify.

-2(2x + 3) = 12

Divide both sides by -2

-2(2x + 3) = 12

-2 -2

2x + 3 = -6

subtract 3 from both sides

2x + 3 - 3 = -6 - 3

2x = -9

Divide both sides by 2

2x/2 = -9/2

x = -9/2
