The area of the shaded region is 294.4 square meters

The given parameters are represented on the figure

By this;

The area of the shaded region is the sum of the area of the major sector and the area of the triangle

The area of the major sector is

A1= ∅/360 * πr²

The area of the triangle is

A2 = 0.5r²sin(x)

So, the total area is

Total = ∅/360 * πr² + 0.5r²sin(x)

This gives

Total = (360 - 130)/360 * 3.14 * 11.1^2 + 0.5 * 11.1^2 * sin(130 deg)

Evaluate

Total = 294.4

Hence, the area of the shaded region is 294.4 square meters

Answer:

25

Step-by-step explanation:

The required amount of strawberries eaten by the friend is given as 25 strawberries.

The equation model is defined as the model of the given situation in the form of an equation using variables and constants.

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Here,
Let the number of strawberries he eat be x,
According to the question,
Strawberries that his friend eat = 5x - 25
Put x = 10
Strawberries that his friend eat = 50 - 25 = 25

Thus, the required amount of strawberries eaten by the friend is given as 25 strawberries.

Answer:

a)

sin30=high of steps/175

sin30=1/2

so

high of steps= 175/2

high of steps=87.5cm

b)

cos30=wide/175

cos30=3^1/2÷2

wide=175*3^1/2÷2

3^1/2=1.73

so

wide=175*1.73/2

wide=151.37

The inequality that describe the situation is (22 x 8) + (5 x S) = 200 and with the money left over, the team will be able to buy 4 pairs of socks, and there will be $4 left over.

Inequality:

Inequality means relation which makes a non-equal comparison between two numbers or other mathematical expressions.

Given,

A basketball team raised $200 to purchase new jerseys.

There are 8 people on the team and jerseys cost $22 each.

With the extra money, the team would like to purchase socks at $5 per pair.

Here we need to find the  inequality that describes the situation and solve it. And also we need to find the greatest number of pairs of socks the team can purchase.

Let S be the number of Socks they brought.

Based on the given details,

The following inequality must be raised:

=> (22 x 8) + (5 x S) = 200

When we solve it,

=> 176 + 5S = 200

=> 5S = 200 - 176

=> 5S = 24

=> S = 24 / 5

Here the S has the value of 4 and the remaining is 4.

Therefore,

with the money left over, the team will be able to buy 4 pairs of socks, and there will be $ 4 left over.

Answer:

1/3

Step-by-step explanation:

Gradient or slope can be found using the point-slope formula:

[tex]y-y_{1} =m(x-x_{1} )[/tex]

We can rearrange the equation to find slope (m) like so:

[tex]m=\frac{y-y_{1} }{x-x_{1} }[/tex]

To use this formula we need to find two well-defined points and use their coordinates.

Let's use (0,2) and (3,3) because they are clear points on the graph.

(0,2) will represent [tex]x[/tex] and [tex]y[/tex] in the equation respectively, and (3,3) our other point will represent [tex]x_{1}[/tex] and [tex]y_{1}[/tex].

Now we just need to plug the numbers into the equation:

[tex]m=\frac{2-3}{0-3} \\\\m=\frac{-1}{-3} \\m=\frac{1}{3}[/tex]

The gradient of the graph is 1/3.

Answer: KCF

Step-by-step explanation: Using this method (just kinda changed?) first change the mixed numbers to improper fractions by multiplying the denominator with the whole number, and adding the numerator to that. Then add a /1 to the regular whole numbers (or the 2nd part of the question) simply multiply both to get the improper fraction. Change into a mixed number as you wish.

The recursive function is Tn = 1/2T(n - 1) where T1 = 300

Recursive function

Here, we have

She decides she is going to take out half of what's left in there at the end of each month.

This means that

Tn = 1/2T(n - 1)

Hence, the recursive function is Tn = 1/2T(n - 1) where T1 = 300

Explicit function

Here, we have

Initial, T1 = 300

Rate, r = 1/2

The explicit function is represented as

Tn = T1 * r^(n-1)

So, we have

Tn = 300 * (1/2)^(n-1)

Hence, the explicit function is Tn = 300 * (1/2)^(n-1)

The wind speed and plane speed is 11 and 96  mph.

It is required to find the speed of the plane in still air and the speed of the wind.

Arithmetic is the branch of mathematics that deals with the study of numbers using various operations on them. Basic operations of math are addition, subtraction, multiplication and division. These operations are denoted by the given symbols.

Given:

Let plane speed be "p".

Let wind speed be "w".

According to given question we have,

p + w = 107 mph

p - w =  85 mph

By the method of elimination we get,

2p = 192

p = 96 mph

The plane speed is 96 mph.

Solve for "w":

p + w = 107

96 + w = 107

w = 11 mph

The wind speed is  11 mph.

Therefore, the wind speed and plane speed is 11 and 96  mph.

Answer:

11.7

Step-by-step explanation:

Using Trigonometric ratios, we can conclude the length of the indicated side is 12.70m.

It can be solved using Trigonometric ratios and Pythagoras theorem

Firstly using Trigonometric ratios

Using Sinθ,

Sinθ = perpendicular / hypotenuse(h)

Sin 39 = 8 / h

0.63 = 8 / h

h = 8 / 0.63

h = 12.70

∴ The length of indicated side is 12.70m

Secondly, using Pythagoras theorem,

(hypotenuse)² = (Altitude)² + (Base)²

⇒ (H)² = 8² + 10²

⇒ (H)² = 64 + 100

⇒ (H)² = 164

⇒ H = √164

⇒ H = 12.80

∴ The length of indicated side is 12.80m

Answer :

The time it will take to travel a distance of 225km is t = 9 h

What is MRU?

 MRU are the acronyms that define the uniform rectilinear movement which is the movement that maintains a variation of the distance with respect to time always constant since the acceleration is null.

We will calculate the speed you have in cyclist with the initial data of traveling a distance of 125km in a time of 5 hours:

Speed = distance / time

Speed = 125km/5h

Speed = 25 km/h

We now determine a time for a 225km course

25 km/h = 225km/t

t = 225km / 25km/h

t = 9 h

The pyramid's volume will increase by 11.79%.

A Pyramid's volume is calculated as:

[tex]V=\frac{B h}{3}[/tex]

Where:

When the height increases from 458 to 512, the initial and final volumes are as follows:

[tex]\begin{aligned}&V_1=\frac{458}{3} b \\&V_2=\frac{512}{3} b\end{aligned}[/tex]

The percentage difference is then calculated as follows:

We obtain:

[tex]\% \text { Change }=\frac{512 b / 3-458 b / 3}{4586 / 3} \times 100 \%\\\% \text { Change }=\frac{54 b / 3}{4586 / 3} \times 100 \%\\\% \text { Change }=0.1179 \times 100 \%\\\% \text { Change }=11.79 \%[/tex]
