1/2 = 2/4 = 3/6,4/8,5/10,6/12,7/14, etc.

Add 1 to the numerator. Add 2 to the denominator.

Answer:

Equivilent fractions of 2/4 include the following: 1/2, 3/6, 4/8, 5/10.

Step-by-step explanation:

The fraction 2/4 can be simplified to 1/2, because 2 is half of 4. And since 3 is half of 6, it can also be simplified to 1/2, making the fractions 2/4 and 3/6 equal to eachother.

I hope that makes sense :)

doing quests, sorry luv. but what does it look like?

C. 104°. The measure of arc QR is equal to 104°.

In Mathematics and Euclidean Geometry, the inscribed angle of a circle is equal to one-half of the central angle or intercepted arc of a circle. This ultimately implies that, the measure of an inscribed angle is one-half the measure of the arc it intercepts based on the inscribed angle theorem.

Since angle S intercepts arc QR, the measure of the angle substended by the intercepted arc can be modeled by the following mathematical equation:

m∠S = 1/2(arc QR).

52 = 1/2 × arc QR

Arc QR = 2 × 52

Arc QR = 104°.

Answer:

x=9

Step-by-step explanation:

Looking at the diagram, we see that four angles are formed by the intersection of two lines. The angles highlighted in blue and green are therefore, vertical angles. We know that vertical angles have equal angle measures meaning that in this case, the measure of the blue angle is equal to the measure of the green angle. Using this, we can now solve for x:

7x+49=2x+94

7x-2x=94-49

5x=45

x=45/5

x=9

Answer:99/1

Step-by-step explanation:110% = 1.1

1.1 * 90 = 99

99= 99/1

Answer:

81 meters.

Step-by-step explanation:

The height (in meters), h(x) of a hovercraft x seconds after takeoff, is modeled by:

[tex]h(x)=-3(x-3)^2+108[/tex]

We are to determine its height at the time of takeoff.

Now, at the time of takeoff, x=0.

We substitute x=0 to solve for h.

[tex]h(0)=-3(0-3)^2+108\\=-3(-3)^2+108\\=-3(9)+108\\=-27+108\\=81$ meters[/tex]

The height of the hovercraft at takeoff is 81 meters.

Answer:

The ratio is 16/65

Step-by-step explanation:

In this question, we are tasked with calculating what ratio represents the cosine of the angle  Q.

In a right angled triangle, there are usually three sides, the hypotenuse, the opposite and the adjacent. Also, there are three angles, 2 asides the ∠90°. The hypotenuse is the longest side which faces the ∠90°, the opposite is that side facing the angle we are interested in while the adjacent is the third side.

Hence we can have only a single hypotenuse, which is the longest side, two opposites(depending on the angle we are concerned about and two adjacents two based on the angle of interest

Firstly, please check attachment for diagrammatic representation.

The ratio for the cosine of an angle is = length of adjacent/length of hypotenuse

From the diagram, with respect to angle Q, the length of the adjacent is 16 while the length of the hypotenuse is 65.

Thus, the ratio representing the cosine of angle Q is 16/65

Answer:Dudley is 50 feet from the flagpole.

Step-by-step explanation:

The situation is represented in the attached diagram. FL represents the flagpole.

A represents the position of Asher.

B represents the position of Baxter.

C represents the position of Cranby.

D represents the position of Dudley.

Looking at the diagram, Dudley is at the same level with Asher but eastwards of the flagpole. The distance of Dudley from the flagpole would be

100 - 50 = 50 feet

Final answer:

Dudley is 100 feet east from the flagpole after the friends have each moved from their starting positions.

Explanation:

The question describes four friends at different locations in relation to a flagpole, and we are asked to determine how far Dudley is from the flagpole after following the described steps by the friends. To solve this, we can visualize or draw a diagram to represent the positions of friends and use the Pythagorean theorem to find the distance Dudley is from the flagpole.

First, let's determine the position of Cranby.

Since Baxter moved 50 feet north from Asher's position and then Cranby moved 100 feet east from Baxter's position, we can see that Cranby is 100 feet east and 50 feet north of the flagpole.

Dudley, standing 50 feet south of Cranby, would thus be at the same north-south position as the flagpole but still 100 feet to the east.

Therefore, Dudley is 100 feet east of the flagpole.

The probability of choosing one white sock and then another white sock from a drawer of 16 socks with 8 being white is 7/30, calculated by multiplying the probability of each event: (1/2) * (7/15).

Initially, there are 8 white socks out of 16 total socks in the drawer. After putting one white sock aside, there are now 7 white socks left out of 15 total socks in the drawer.

The probability for each event is calculated separately:
The probability of picking a white sock first: 8/16 or 1/2.
Then the probability of picking another white sock: 7/15.

To find the overall probability of both events occurring in sequence (one after the other), we multiply the probabilities of the two independent events:

(1/2) * (7/15) = 7/30.

So the correct answer is A. 7/30.

Answer: 3

Step-by-step explanation:

Evaluate is a fancy word for putting the value assigned into the equation and see what result you get.

[tex]-2x^2-4x+3\\x=-2[/tex]

[tex]-2(-2)^2-4(-2)+3\\-2(4)+8+3\\-8+8+3\\3[/tex]

To evaluate the expression −2x²−4x+3 for x=−2, substitute x with -2 and perform the operations: square x, multiply by -2, multiply -4 by x, and add the results to get the final answer of 3.

To evaluate the expression
−2x²−4x+3 when x=−2, we need to substitute x with −2 and then follow the order of operations, which is to perform exponentiation before multiplication and addition.

Thus, −2x²−4x+3 evaluates to 3 when x is −2.

Answer:

[tex]\frac{x^{2} }{36}+\frac{y^2}{16}=1[/tex]

Step-by-step explanation:

Center of the ellipse is at origin (0, 0)

So (h, k) = (0, 0)

Length of major axis = 12

2a = 12

⇒ a = 6

Length of minor axis = 8

⇒ 2b = 8

⇒ b = 4

Since focus is on the x-axis, so it's a horizontal ellipse.

Equation of the horizontal ellipse is in the form of,

[tex]\frac{(x-h)^{2} }{a^2}+\frac{(y-k)^2}{b^2}=1[/tex]

By substituting the given values of a, b, and (h, k)

[tex]\frac{(x-0)^{2}}{6^2}+\frac{(y-0)^2}{4^2}=1[/tex]

[tex]\frac{x^{2} }{36}+\frac{y^2}{16}=1[/tex]

Answer:

It is 5 km/hour

Step-by-step explanation:

Let w represents the speed of the water

The speed can be found by following:

→ distance = speed x time → speed = distance / time (1)

If the boat goes downstream the total speed of the boat is the speed of the boat in still water + the speed of the water. Substitute the values into equation 1:

→ (the speed of the boat in still water + the speed of the water) = 120 / 4

Since the speed of the boat in still water is 25

→ 25 + w = 120 / 4

→ w + 25 = 30

→ w = 5

By setting up and solving the equation 4x = 5x - 4, we can find the value of x. Substituting the value of x into the expression for AM or MB, we can find the length of AB.

In order to find AB, we need to solve for x since AM and MB are given in terms of x. Since line L bisects AB at point M, AM and MB should be equal. So, we can set up the equation 4x = 5x - 4 and solve for x.

4x = 5x - 4

-x = -4

x = 4

Now that we have the value of x, we can substitute it back into one of the expressions for AM or MB to find the length of AB. Using AM = 4x, we have AB = AM + MB = (4 * 4) + (5 * 4 - 4) = 16 + 16 = 32.

Therefore, AB is 32 units long.

Answer:

the answer to this question would be 47.5

Answer:

Step-by-step explanation:

Given that,

0 = 0.25x² - 8x

This is a quadratic equation, since it has the highest power of x to be 2.

0.25x² - 8x = 0

Simplify this by bring out x

x(0.25x - 8) = 0

So, if a × b = 0, it is either a = 0 or b = 0, if the multiplication of two number is 0, then it is either one of the number is 0 or both numbers is 0

So,

x(0.25x - 8) = 0

x = 0. OR. 0.25x - 8 = 0

x = 0. OR. 0.25x = 8

x = 0. OR. x = 8 / 0.25

x = 0. OR. x = 32.

So, the solution that describe the system is

0.25(0)² - 8(0)

OR

0.25(32²) - 8(32)
