Step-by-step explanation:

straight line =180

180-120=60

Answer:

There are 20 long tables and 5 round tables y.

Step-by-step explanation:

Given:

long tables x + round tables y = total of 25 tables

8seats ·x +6seats ·y = 190 seats

Find x and y:

x+y= 25 so x= 25-y

8x+6y = 190, we substitute x for 25-y to find y

8(25-y) +6y = 190, we distribute 8 in parenthesis

200 -8y+6y = 190, combine like terms

200 -2y = 190, subtract 200 from both sides

-2y = 190-200, combine like terms

-2y = -10, divide both sides by -2

y = 5

x+y = 25, substitute y for 5

x+5 = 25, subtract 5 from both sides

x= 20

Conclusion:

There are 20 long tables and 5 round tables y.

20·8+5·6 = 160+30 = 190 seats

Answer:

42 lies between 6 and 7

Step-by-step explanation:

We know that √42 will lie between √36 and √49

And √36=6; √49=7

Hence we can be sure that √42 lies between 6 and 7

Answer:

Area = 43.26

Step-by-step explanation:

There is a short way to do this.

Area = 1/2 s*t * Sin(R)

s = 14

t = 7

Area = 1/2 * 14 * 7 * Sin(62)

Area = 7 * 7 * sin(62)

Area = 49 * sin(62)

Area = 43.26

==================

There is another way you could do this.

Use the Cos law to find r

Then use Heron's formula to find the area. Trust me, you don't want to do that.

Doing the way I suggested gives 43.19. The difference is in what I did in the rounding. But I wouldn't want to type all the numbers.

The vertices of the image reflected across the line y = x are; P'(-4,-7), Q'(-8, -7), R'(-3, 3)

We are given the vertices of the triangle as;

P(-7,-4), Q(-7, -8), and R(3, -3)

Now, in transformations, there are different types such as;

Dilation

Reflection

Rotation

Translation

However, in this case we are dealing with reflection of triangle PQR.

Now, the transformation rule for reflection across the line y = x is;

(x, y) → (y, x)

Thus, applying the reflection transformation rule above to our triangle coordinates gives us;

P(-7,-4) → P'(-4, -7)

Q (-7, -8) → Q'(-8, -7)

R(3, -3) → R'(-3, 3)

The solution of the equation, 3x - 1 / x + 2 = x + 5 / 2x - 1 is not extraneous.

Extraneous solution occur because squaring both sides of a square root equation results in 2 solutions (the positive and negative number).

Therefore, let's solve the equation to know if it's extraneous.

Hence,

3x - 1 / x + 2 = x + 5 / 2x - 1

cross multiply

(3x - 1)(2x - 1) = (x + 2)(x + 5)

6x² - 3x -2x + 1 = x² + 5x + 2x + 10

6x² - x² - 5x - 7x + 1 - 10 = 0

5x² - 12x - 9 = 0

Hence,

5x² - 12x - 9 = 0

(x - 3)(x + 3 / 5)

x = 3 or x = -3 / 5

Therefore, the equation is not extraneous

Answer:

The correct answer is -

x+2y = 23

2x+3y= 39

Step-by-step explanation:

given:

cost of family 1 = 23

number of adults in family one = 1

number of children = 2

cost of family 2 = 39

number of adults in family 1 = 2

number of children = 3

solution:

for the first condition of family one-

In this case, there is only one adult and 2 children and they paid 23 then if the adult cost is x and the children ticket cost is y then

number of adults*x+number of children*y = total cost

1*x + 2*y = 23

x+2y= 23 .......equation 1.

for family two:

In this case, there is two adult and 3 children and they paid 39 then if the adult cost is x and the children ticket cost is y then

number of adults*x+number of children*y = total cost

2*x + 3*y = 39

= 2x+3y = 39....... equation 2

thus, the correct equations are:

x+2y = 23

2x+3y= 39

The length of the equilateral triangle = 4.8m

Given that,

The area of the equilateral triangle = 10.2 m²

The formula for the area of an equilateral triangle = \(\sqrt{3} /4 a^{2}\)

Therefore,  

\(\sqrt{3} /4 a^{2}\) = 10.2

\(a^{2}\) = 10.2 × \(4/\sqrt{3}\)

\(a^{2}\) = 10.2 × 4/ 1.732

\(a\) = 4.85

For the given inequality states that the function \(\(f(x)\)\) is bounded between \(\(\sqrt{10-7x^2}\)\) and \(\(\sqrt{10-x^2}\)\) for \(\(x\)\) in the interval \(\([-1, 1]\)\). The limit of \(\(f(x)\)\) as \(\(x\)\) approaches 0 is \(\(\sqrt{10}\)\).

To find the limit of \(\(f(x)\)\) as \(\(x\)\) approaches 0, we need to determine the behavior of \(\(f(x)\)\) as \(\(x\)\) gets arbitrarily close to 0 within the given inequality.

- The given inequality states that the function \(\(f(x)\)\) is bounded between \(\(\sqrt{10-7x^2}\)\) and \(\(\sqrt{10-x^2}\)\) for \(\(x\)\) in the interval \(\([-1, 1]\)\).

- As \(\(x\)\) approaches 0 within this interval, both \(\(\sqrt{10-7x^2}\)\\ \\\) and \(\(\sqrt{10-x^2}\)\) converge to \(\(\sqrt{10}\)\).

- Since \(\(f(x)\)\) is bounded between these two functions, its behavior is also restricted to \(\(\sqrt{10}\)\) as \(\(x\)\) approaches 0.

- Therefore, the limit of \(\(f(x)\)\) as \(\(x\)\) approaches 0 is\(\(\sqrt{10}\)\).

Answer:

3, 6, 9 (the multiples of three within 11)

3 out of 11 numbers are multiples of 3

so you have a 3 out of 11 probability to grab a multiple of three

3/11 is your answer

Step-by-step explanation:

Probability of picking a ball of multiple of 3 is equals to (3/11).

" Probability is a mathematical expression which represents the ratio of number of favourable outcomes to the total number of outcomes."

Formula used

Probability = \(\frac{Number of favourable outcomes}{Total number of outcomes}\)

According to the question,

'B' represents the ball

Possible outcomes = { B₁, B₂, B₃, ...., B₁₀, B₁₁}

favourable outcomes multiple of 3 = { B₃, B₆, B₉}

Total number of outcomes= 11

Number of favourable outcomes = 3

Substitute the value in the formula we get,

Probability of picking ball multiple of 3 = ( 3 / 11)

Hence, probability of picking a ball of multiple of 3 is equals to (3/11).
