The figure has a rotational symmetry and the number of lines of symmetry is 3

How to determine the rotational symmetry?

The given figure is an equilateral triangle.

An equilateral triangle has 3 equal sides and 3 equal angles.

This means that it has a rotational symmetry and the number of lines of symmetry is 3.

The angle of rotational symmetry is calculated as:

Angle = 180/3

Evaluate

Angle = 60

Hence, the angle of rotational symmetry is 60

The graph of function g (x) predicts the profit of jimmy's famous Jer*y for a week. The x-axis represents the number of employees earning overtime for the week. The y-axis is the business's profit for the week in hundreds of dollars.

Answers

By identifying the maximums, we see that in each blank we need to write:

1) 2

2) 2

3) greater.

How to complete the given statement?

First, we need to find the maximum of the function g(x).

You can see that for x = 2 we have the maximum of the parabola, which gives y = 9.

Then the maximum profit is got when 2 employees earn overtime.

We also need to find the maximum for the table. Notice that the maximum value of the table also happens for x = 2, and this time the maximum is y = 16.

So we can see that the maximum of Cathy's cupcakes is larger than the maximum of Jimmy's.

there is 19 games if they tied 16 then that 16 points so 28 - 16= 12  

then 4 games left so 4 times 3 is 12

At the end of the tournament, team Olympus have tied for 13,10,7,4,1 times

What is inequality?

A statement of an order relationship—greater than, greater than or equal to, less than, or less than or equal to—between two numbers or algebraic expressions.

According to question

In a football tournament, each team plays exactly 19 games.

Points for every win (w) = 3

Points for every tie (t)= 1

Points for every loose = 0

Olympus got a total of 28 points

i.e  3w + t = 28 ---------(1)

And each team plays  19 games

T + W  ≤  19 --------------(2)

and T , W ≥ 0

from equation (1) and (2)

=> 2W  ≥  9

=> W ≥ 4.5  

( match can be won in integers only )

=> W  ≥  5

Step-by-step explanation:

For 10π, we can simplify π into 3.14 for an approximate amount. 3.14*10=31.4

For the square root of ten, we can estimate it's between 10 and 11 since 10 squared is 100 and 11 squared is 121.

Answer:

See explanation

Step-by-step explanation:

First, we have to put the expressions into numbers. For the square root of 101, it doesn't divide evenly into any whole number. We do know that 10^2 is 100, and 11^2 is 121. That means the square root of 101 is between 10 and 11. Pi is equal to 3.14, so we just multiply 10 by 3.14. If we do this, we get 31.4. From here we can rank the numbers in order from greatest to smallest.

31.4 (10pi) is greater than

The height of a woman whose femur (f) measures 49 centimeters is equal to 173.15‬ centimeters.

What is a function?

A function can be defined as a mathematical expression that defines and represents the relationship that exists between two or more variable of a data set.

In order to determine the height of a woman whose femur (f) measures 49 centimeters, we would substitute this numerical value into the first function as follows:

G(f) = 2.57f + 47.22

G(49) = 2.57(49) + 47.22

G(49) = 125.93 + 47.22

G(49) = 173.15‬ centimeters.

Answer:

y = 1/40x + 20

Step-by-step explanation:

Slope-intercept equation format:

m = slope/ gradient/ constant of variation/ rate of change

b = y-intercept

To find the slope, use the formula:

[tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

Find  two random points:

1 - (0.5, 40) , 2 - (1, 60)

Solve:

[tex]\frac{20}{0.5}[/tex]

Divide:

The y-intercept is when the x-coordinate is equal to 0.

The y-intercept is always the beginning.

So observing the graph, the first point is (0, 20)

The x-coordinate is 0.

Y intercept = 20.

How to calculate the area of trapezium B using the scale factor

Answers

Answer:

  612.5 cm²

Step-by-step explanation:

The ratio of areas of similar figures is the square of the scale factor. The scale factor is the ratio of corresponding side lengths. Here, we must find the scale factor.

__

missing side of A

The only given side of trapezium B corresponds to an unknown side of trapezium A. We can find the length of that unknown side using the area formula.

  A = 1/2(b1 +b2)h . . . . . parallel sides b1, b2; height h

  98 cm² = 1/2(16 cm +b2)(7 cm) . . . . use known values

  28 cm = 16 cm +b2 . . . . . . . . . . divide by 3.5 cm

  b2 = 12 cm . . . . . . . . . . . . . . subtract 16 cm

The top side of trapezium A is 12 cm long.

scale factor

Now we have the lengths of corresponding (top) sides, so we can find the scale factor. It is their ratio. We choose to express it as (size of B)/(size of A).,

  k = (30 cm)/(12 cm) = 2.5

area of B

The area of trapezium B will be that of trapezium A multiplied by the square of the scale factor:

  area B = (k²)(area A) = (2.5²)(area A)

  area B = 6.25×98 cm² = 612.5 cm²

The area of trapezium B is 612.5 cm².
