Answer:

110°

Step-by-step explanation:

mFG = 2×<FEG = 2×55 = 110°

Answered by GAUTHMATH

The value of the angle or periphery FG will be 110°.

A circle is a geometric shape that is created by drawing a point in an orbit around a fixed point while maintaining a fixed distance.

The longest line which can be drawn inside the circle will be the diameter.

Area of circle = πr² and the perimeter of circle = 2πr where r is the radius of the circle.

By the circle theorem;

According to the theorem, an angle within a circle is half of the center angle within the circle that subtends the same arc.

Given the ∠FEG = 55°

So angle FG = 2 × ∠FEG

angle FG = 2 × 55° = 110°

Hence angle FG will be 110°.

Answer:

The shortest side of the triangle is 18

Step-by-step explanation:

Let the sides the triangle be x, y and z.

From the question, the perimeter of the rectangle is 64, that is

x + y + z = 64 ...... (1)

Also, the ratio of two of its sides is 4:3, that is x:y = 4:3, then we can write that x/y = 4/3 ⇒ 3x = 4y ...... (2)

The third side, z, is 20 less than the sum of the other two, that is

z + 20 = x + y ...... (3)

Substitute equation (3) into (1)

Then,

z + 20 + z = 64

2z +20 = 64

2z = 64 - 20

2z = 44

z = 44/2 k

z = 22

From equation (3)

z + 20 = x + y

Then, k

22 + 20 = x +y

42 = x + y

x = 42 - y ...... (4)

Substitute this into equation 2

3x = 4y

3(42-y) = 4y

126 - 3y = 4y

4y + 3y = 126

7y = 126

y = 126/7

y = 18

Substitute this into equation (4)

x = 42 - y

x = 42 - 18

x = 24

∴ x = 24, y = 18 and z = 22

Hence, the shortest side of the triangle is 18.

Answer: 825

Step-by-step explanation:

Plug in the values for v = π*r²*h

So, your new equation is v = π*5²*11 (I got 5 because 10 is the diameter, the radius is half the diameter, therefore r = 5.)

The question is also telling us to replace π with 3.

now we solve, after gathering all of our information.

v = 3*5²*11

v=3*25*11

v=75*11

v=825

Answer:

1:1:√ 2

Step-by-step explanation:

Answer:

u = 14

v = 14

Step-by-step explanation:

since both angles around the 90 degree angle are the same, also the sides need to be of equal length. v = u

so, we can use Pythagoras

(14×sqrt(2))² = u² + u² = 2u²

196×2 = 2u²

196 = u²

u = 14 = v

Answer:

20 ladies

30 gents

Step-by-step explanation:

Let :

x = number of ladies

50 - x = number of gents

total weight of the ladies = 40x

total weight of the gents = 50(50 - x) = 2500 - 50x

Average weight : (40x +2500 -  50x) / 50 = 46

cross multiply

2500 - 10x = 2300

combine like terms

2500 - 2300 = 10x

200 = 10x

x = 20 = number of ladies

Number of men = 50 - 20 = 30  

Answer:

28.3

Step-by-step explanation:

Use the Tangent

Tan(theta) = opposite over adjacent.

opposite (defined as the line that does not make up the angle) = 17

Theta = 31

adjacent (one of the lines making up the angle) = x

Tan(31) = 0.6009

Tan(31) = 17/x             Multiply both sides by x

x*tan(31) = 17              Divide by tan 31

x = 17/tan31

x = 17 / 0.6009

x = 28.29

Rounded to the nearest 1/10 is 28.3

The six trigonometric ratios are sine (sin), cosine (cos), tangent (tan), cotangent (cot), cosecant (cosec), and secant (sec). In geometry, trigonometry is a branch of mathematics that deals with the sides and angles of a right-angled triangle. Therefore, trig ratios are evaluated with respect to sides and angles.  

The trigonometry ratios for a specific angle ‘θ’ is given below:

Trigonometric Ratios

Sin θ Opposite Side to θ/Hypotenuse

Cos θ Adjacent Side to θ/Hypotenuse

Tan θ Opposite Side/Adjacent Side & Sin θ/Cos θ

Cot θ Adjacent Side/Opposite Side & 1/tan θ

Sec θ Hypotenuse/Adjacent Side & 1/cos θ

Cosec θ Hypotenuse/Opposite Side & 1/sin θ

Note: Opposite side is the perpendicular side and the adjacent side is the base of the right-triangle. Also, check out trigonometric functions to learn about each of these ratios or functions in detail.Trigonometric Identities

Definition

Trigonometric Ratios are defined as the values of all the trigonometric functions based on the value of the ratio of sides in a right-angled triangle. The ratios of sides of a right-angled triangle with respect to any of its acute angles are known as the trigonometric ratios of that particular angle.

The three sides of the right triangle are:

Hypotenuse (the longest side)

Perpendicular (opposite side to the angle)

Base (Adjacent side to the angle)

Answer:

The function will have a vertical compression when 0 < α < 1

Step-by-step explanation:

The vertex form of a quadratic function showing the factors of the transformation of the function, is presented as follows;

[tex]f(x) = a \cdot \left(\dfrac{x}{c} - h \right)^2 + k[/tex]

The vertical scaling of the function (compression and stretching) is given by the value of the α control coefficient

A vertical stretch occurs when α > 1, while a vertical compression occurs when 0 < α < 1

Therefore, in order for a quadratic function to have a vertical compression, 0 < α < 1.

• • •

The simplified expression is 99.3333 (rounded to four decimal places).

To simplify the expression 62 + 2{56/(4 multiplied by 2) - 5}, we'll follow the order of operations (also known as PEMDAS).

First, within the innermost parentheses, we have 4 multiplied by 2, which equals 8. Then, we subtract 5 from 8, resulting in 3.

Next, we have 56 divided by 3, which equals 18.6667 (rounded to four decimal places).

Now, we'll move to the outer set of curly braces. We multiply 18.6667 by 2, giving us 37.3333 (rounded to four decimal places).

Finally, we add 62 to 37.3333, resulting in 99.3333 (rounded to four decimal places).

Answer:

94.2 cm^3.

Step-by-step explanation:

Volume of a cone = 1/3πr^2h

The radius of the cone = 1/2 * 6 = 3

So here the volume is:

1/3 * π *  3^2 * 10

= 94.247

So here, for basically any quadratic function, the domain is: [tex]x \in \mathbb{R}[/tex].

Now right off the bat, that means C and D are out.

Also, since this graph has a negative sign in front of the x^2, that means it is facing downwards and so it has a maximum. The only option that leaves us with is A.

Answer:

15 weeks

Step-by-step explanation:

Let the number of weeks = x.

At the end of x weeks,

Jeremy has 120 + 14x,

and Katie has 180 + 10x

We want to know when their amounts are equal.

120 + 14x = 180 + 10x

4x = 60

x = 15

Answer: 15 weeks

Answer:

15 weeks

Step-by-step explanation:

One is given the following information:

Jeremy

Katie

Let the parameter (x) represent the number of weeks passed. Parameter (y) is the amount in the account, (S) represents the amount in the account to start with and (A) represents the amount added to the account every week. One can use the following general equation to represent the situation:

y = S + Ax

Substitute the given information into the equation for each person:

Jeremy: y = 120 + 14x

Katie: y = 180 + 10x

One is asked to find the point in time when the two account have the same amount of money. Therefore, set the two equations equal to each other and solve:

y = 120 + 14x = 180 + 10x

Inverse operations,

120 + 14x = 180 + 10x

4x = 60

x = 15

15 weeks will pass before Katie and Jeremy have the same amount of money in their accounts.
