hello can you help me solve this trigonometry question and in the question use pi to answer it

Answer:

x = 8.33

Explanation:

y varies directly with x if y can be calculated as a constant k times x. So:

y = k*x

If y is equal to 75 and x is equal to 25, we can calculate the value of k as:

Therefore, y = 3*x

So, to find x when y = 25, we need to replace y by 25 and solve for x as follows:

Therefore, x is equal to 8.33

Answer:

the anwser is 110

Step-by-step explanation:

The price before was £108.9 because 10% of £121 is £12.1 so if you subtract that you would get £108.9

In a right triangle, there are 2 acute angles and 1 right angle.

Let x be the measure of the larger acute angle, using the triangle sum theorem (that states that the sum of the interior angles of a triangle is 180) we have that:

The larger acute angle measures 72°.

Recall that:

Therefore the given equation has no solutions.

Answer: Option B.

Answer:

3487

Step-by-step explanation:

well, the change is just 112 - 96 = 16.

now if we take 112 as the 100%, what's 16 off of it in percentage?

[tex]\begin{array}{ccll} amount&\%\\ \cline{1-2} 112 & 100\\ 16& x \end{array} \implies \cfrac{112}{16}~~=~~\cfrac{100}{x} \\\\\\ 7=\cfrac{100}{x}\implies 7x=100\implies x=\cfrac{100}{7}\implies x\approx 14.29[/tex]

The order of values in ascending order will be -4<-2<2<2.64<4<16 as the definition of ascending order says, "When numbers are arranged in ascending order, they are done so from smallest to largest".

When numbers are arranged in ascending order, they are done so from smallest to largest. Climbing down the stairs of numbers starting with their highest value is another way to think of descending. The slide is descended while moving down it. Ascending order, in which the numbers are arranged from lower value to higher value, is the opposite of descending order. A number can be arranged in ascending order by going from smallest to largest from left to right.

Here,

4²=16

-√4=-2

√4²=4

-2√4=-4

6-4=2

√7=2.64

-4<-2<2<2.64<4<16

According to the definition of ascending order, "When numbers are arranged in ascending order, they are done so from smallest to largest," the order of values in ascending order will be -4<-2<2<2.64<4<16.

Given:

There are 5 numbers followed by 2 letters.

Solution:

To find the answer, we will have a plate number that consists of 5 numbers followed by 2 letters. In that 5 numbers, each place has 10 choices-from 0 to 9. It will be: 10 * 10 * 10 * 10 * 10 = 100,000 .

Now, for the letters, there are 26 letters in the alphabet. We have two places for the letters and each place have 26 choices-from A to Z that will give us: 26 * 26 = 676

We will now multiply the acquired data for both the numbers and letters to arrive at the correct answer.

100,000 * 676 = 67,600,000

1) Given that AC is the line segment made up by AB + BC We can set this equation:

AC=AB+BC

13x-17=2x+4+19 Combining like terms

13x-2x -17=2x-2x+23

11x -17=23

11x -17+17 = 23 +17

11x = 40 Dividing both sides by 11

Answer:

The speed of wind is 75 miles / hour

Step-by-step explanation:

Let's assume

speed of airplane is x miles /hour

speed of wind is y miles /hour

An airplane travels 600 miles against the wind in 4 hours

against wind means resultant speed will be less

so, speed =x-y

total distance traveled in 4 hour is

and this has to be equal to 600

Divide both sides by 4

makes the return trip with then same wind in 2 hours

with wind means resultant speed will be more

so, speed =x+y

total distance traveled in 2 hour is

and this has to be equal to 600

Divide both sides by 2

So, we get system of equations

now, we can solve it by adding both equations

now, we can solve for x

now, we can  find y by plugging x into any one equation

The graph that represents the given linear function is attached below.

We are given a function. A function connects an input with an output. It is analogous to a machine with an input and an output. And the outcome is somehow connected to the input. The equation is linear in nature. It represents a straight line. The equation is given below.

(y - 4) = (4/3)(x - 2)

A line's general equation in slope-intercept form is y = mx + c. We will convert the given equation into this form.

y - 4 = (4/3)x - 8/3

y = (4/3)x - 8/3 + 4

y = (4/3)x + 4/3

The slope of the given equation is 4/3. The y-intercept for the given equation is 4/3.

it is proven that 6√5 between 12 and 18, Irrational numbers

What are Irrational numbers?

The group of real numbers known as irrational numbers are those that cannot be written as a fraction of the form p/q, where p and q are integers. Additionally, the decimal expansion of an irrational integer is neither terminating nor recurring.

Irrational numbers are real numbers that cannot be expressed as a straightforward fraction. These cannot be stated as ratios, such as p/q, where p and q are integers, q0. It is a contradiction of rational numbers.

It has been given in question 4 < 5 < 9 and we have to show 6√5 is between 12 and 18.

For box number 1.

4 < 5 < 9 ⇒ √4 < √5 < √9

For the box number 2.

√4 < √5 < √9    ⇒   2 < √5 < 3

For the box number 3.

we multiply the inequality by 6.

6×(2 < √5 < 3)

⇒ 6×2 < 6×√5 < 6×3

So the 6×2 < 6×√5 < 6×3

⇒ 12 < 6√5 < 18

Hence it is proven that 6√5 between 12 and 18.

The shop for which Betsie should buy the 250 envelopes from, using proportions, is Value World.

A proportion is a fraction of a total amount, and this fraction is used to build relations, using basic arithmetic operations such as multiplication or division, to obtain the desired measures.

In this problem, the final price is obtained as follows:

Hence the final price at Value World is given as follows:

1.99/10 = 0.119.

She will pay for 2/3 of the 250 packs, as she buys 2 and gets one free, hence:

2/3 x 250 x 0.119 = £19.83.

At Letters2go, the final price is obtained as follows:

3.19/25 x 250 = £31.90.

Due to the lower price, she should purchase her envelopes at Value World.

It implies that when F(x) shifts 7 units to the left, we get the value equal to G. (x). As a result, the graph of G(x) is the graph of F(x) with 7 units added to the left.

The graph of g is the reflection of the graph of f. If g(x) = f(-x), then the graph of g is obtained from the graph of f by reflecting about the y-axis.

For instance, the result of multiplying f(x) and g(x) is h(x) = fg (x), or h(x)=f(x)g (x). if f is the function denoted by f(x) = x2 and g is the function denoted by g(x) = x + 3.

Therefore,

The Correct answer is : The two functions G(x) and F are provided to us (x).

We must determine which assertion most accurately contrasts the graphs of G(x) and F(x).

Suppose

F(x) = x [/ tex]

G(x) = x-7

When x = 1 is substituted

So, F(x) = 1

G(x) = 1-7 = -6

It implies that we obtain the value equal to the value of G when F(x) shifts 7 units to the left (x).

The graph of G(x) is therefore the graph of F(x) with 7 units added to the left.

The area of this semi-circle is 38.28 cm²  and this can be determined by using the formula of area of the semi-circle.

Given :

The diameter of the semi-circle is 10 cm.

The area of the circle is given by the formula:
