Answer:

120

Step-by-step explanation:

The LCM of 24 and 30 is 120. To find the least common multiple (LCM) of 24 and 30, we need to find the multiples of 24 and 30 (multiples of 24 = 24, 48, 72, 96 . . . 120; multiples of 30 = 30, 60, 90, 120) and choose the smallest multiple that is exactly divisible by 24 and 30, i.e., 120.

Answer:

A

Step-by-step explanation:

The formula to find the perimeter of a rhombus is p=4a

and 4 times 1 2/3= 4 2/3

Let's represent the number with the variable "x". According to the given property, we can write the following equation:

3(x + 4) < 7x

Now, let's solve this inequality to find the range of numbers that satisfy the property.

3x + 12 < 7x

Subtract 3x from both sides:

12 < 4x

Divide both sides by 4 (since the coefficient of x is 4):

3 < x

So, the range of numbers that satisfy the given property is x > 3.

Therefore, any number greater than 3 will satisfy the condition. For example, 4, 5, 6, 7, 8, etc.Step-by-step explanation:

The coordinates of the vertex of the parabola are (3, -7). The focus of the parabola is located at (3, -3). The equation of the directrix is y = -11.

The given equation of the parabola is in the form (x - h)^2 = 4p(y - k), where (h, k) represents the vertex and p represents the distance between the vertex and the focus/directrix.

Comparing the given equation with the standard form, we can see that the vertex is at (3, -7).

The coefficient 4p in this case is 16, so p = 4. Since the parabola opens upward, the focus will be p units above the vertex. Therefore, the focus is located at (3, -7 + 4) = (3, -3).

To find the directrix, we need to consider the distance p below the vertex. Since the parabola opens upward, the directrix will be p units below the vertex. Hence, the equation of the directrix is y = -7 - 4 = -11.

In summary, the coordinates of the vertex are (3, -7), the focus is located at (3, -3), and the equation of the directrix is y = -11.

Answer:

x = \(\sqrt{165}\)

Step-by-step explanation:

Pythagorean Theorm: a^2 + b^2 = c^2

a^2 + b^2 = c^2

14^2 + x^2 = 19^2

196 + x^2 = 361

x^2 = 165

x = \(\sqrt{165}\)

Answer:

33

Step-by-step explanation:

Let x= be the amount in the account with .5%

Let y be the amount in the account with .25%

We know that interest is

I = PRT

I = 21.25 and time is 1 year so t=1

I = x(.005)(1) + y (.0025)

We also know that the amount invested is 5000

x+y = 5000

The system of equations is

21.25 = .005x + .0025y

x+y = 5000

21.25 = .005x+.0025y

Let x = 0

21.25 = .0025y

21.25/.0025 =y

The y intercept is 8500

Let y =0

21.25 = .005x

21.25/.005 =x

The x intercept is 4250

x+y = 5000

Let x = 0

The y intercept is 5000

Let y =0

The x intercept is 5000

Using substitution

x = 5000-y

21.25 = .005(5000-y) + .0025y

21.25 = 25 - .005y +.0025y

21.25-25 = -.0025y

-3.75 = -.0025y

-3.75/-.0025 = y

1500 = y

Now find x

x+y = 5000

x+1500=5000

x = 5000-1500

x = 3500

The side AC corresponds to the side AC in the other triangle and the length of BC is 15 units

For two triangles to be similar, the corresponding sides of the triangles must be in proportion

Having said  that

The side AC corresponds to the side AC in the other triangle

The length BC is calculated as

BC/9 = 25/15

Express as products

So, we have

The term “inverse” in mathematics generally refers to an operation that undoes or reverses another operation. However, the phrase "inverse of maths tools" doesn't really make sense because “maths tools” is not a specific mathematical operation.

Mathematical tools can refer to various instruments or techniques used in mathematics, such as calculators, rulers, compasses, graph paper, software, etc. Each of these tools has its own purpose and may or may not have an inverse operation or tool associated with it.

For example, the inverse of addition is subtraction, the inverse of multiplication is division, and the inverse of differentiation is integration. However, it's not clear what the inverse of a “maths tool” would be.

Therefore,  a) The inverse of “Add 25” would be “Subtract 25.”What is the  b) The inverse of “Divide -18” would be “Multiply -18.” c) The inverse of “Subtract 3” would be “Add 3.” d) The inverse of “Multiply 14” would be “Divide 14.”

Based on their given probabilities, e would expect the color blue or green to be spun approximately 75 times in this experiment.

To find the expected number of times the color blue or green will be spun, we first need to add their probabilities:

0.25 + 0.125 = 0.375

This means that, on average, we would expect to see blue or green spun 0.375 times for every spin. To find the expected number of times this will happen over 200 spins, we can multiply the probability by the number of spins:

0.375 x 200 = 75

The product of the given fractions is 224/61.

To calculate the product of the given fractions, let's simplify and cancel out any common factors.

We have:

Starting from the numerator and denominator of the first fraction, we observe the following cancellations:

5 in the numerator and denominator cancel out.

7 in the numerator and denominator cancel out.

9 in the numerator and denominator cancel out.

11 in the numerator and denominator cancel out.

(4/1) x (1/28) x (29/37) x (31/1) x (1/35) x (37/29)

This simplifies to:

(4 x 1 x 29 x 31 x 37) / (1 x 28 x 37 x 29 x 35)

Simplifying further:

(4 x 29 x 31) / (28 x 35)

We can calculate this to get the final result:

(4 x 29 x 31) / (28 x 35) = 3584 / 980 = 224 / 61.

The side RT of the triangle is 13 m.

Trigonometry is a branch of mathematics dealing with the relationship between the ratios of the sides of a right-angled triangle with its angles.

The sine law is a mathematical formula used in trigonometry to relate the sides and angles of a triangle. The sine law states that:

a/sin(A) = b/sin(B) = c/sin(C)

where:

a, b, and c are the lengths of the sides of the triangle

A, B, and C are the angles opposite those sides

Using sine law:

RT/sin 34° = ST/sin 109°

RT/sin 34° = 22/sin 109°

RT = (22 * sin 34°)/(sin 109°)

RT = 13 m

The slope of the line that passes through the points is

Solution-

As there is a single line passing through all these points, so taking any two points and then applying the formula for slope will give the slope of the line.

The points are,

(-14, 8), (-7, 6), (0, 4), (7, 2), (14, 0)

Taking two points as, (0, 4), (7, 2)

x₁ = 0

y₁ = 4

x₂ = 7

y₂ = 2

Putting the values,

Therefore, the slope of the line that passes through the points is

Step-by-step explanation:

The slope of the line that passes through the points in the table is -2/7.

Slope of a line is the ratio of the change in y coordinates to the change in the x coordinates of two points given.

Given a table which shows the points on the line.

Slope of a line passing through two points (x, y) and (x', y') is,

Slope = (y' - y) / (x' - x)

Take any two points on the line.

(0, 4) and (7, 2).

Slope = (2 - 4) / (7 - 0) = -2/7

Hence the slope of the line is -2/7.

The values of the parameters for this problem are given as follows:

p = 0.02, n = 100.

The probability of 3 or more deaf people are given as follows:

P(X >= 3) = 1 - P(X < 3).

In which:

P(X < 3) = P(X = 0) + P(X = 1) + P(X = 2).

Hence:

Thus:

P(X < 3) = P(X = 0) + P(X = 1) + P(X = 2)

P(X < 3) = 0.1326 + 0.2707 + 0.2334

P(X < 3) = 0.6367.

P(X >= 3) = 1 - P(X < 3).

P(X >= 3) = 1 - 0.6367.
