what is the second step when multiplying mixed numbers.

Answer:6

Step-by-step explanation:

CA/CB = 21/14 or 3/2

So make 18 the numerator by multiplying both values in the fraction by 6

18/12

BD = 6

The total interest you will earn in 30 years is approximately $241.61.

To calculate the total interest earned in 30 years, we need to use the formula for compound interest:
A = P(1 + r/n)^(nt) - P
Where:
A = the future value of the investment
P = the principal amount (initial deposit)
r = the annual interest rate (in decimal form)
n = the number of times the interest is compounded per year
t = the number of years
In this case, the principal amount is $200, the annual interest rate is 3% (or 0.03 as a decimal), the interest is compounded monthly (so n = 12), and the time period is 30 years (so t = 30).
Plugging in these values into the formula:
A = 200(1 + 0.03/12)^(12*30) - 200
Now we can simplify and calculate:
A = 200(1.0025)^(360) - 200
A = 200(2.208040033) - 200
A ≈ 441.6080066 - 200
A ≈ 241.6080066

The correct option is (C) variable.

Seven is not an example of variable.

A variable can be taken as a letter or number or a symbol which is not fixed that mean its value may be change any time .

An expression is consist of multiple symbols, letters or numbers .Expression is a proper mathematical statement consist of single letter or may be multiple letter combine with some operators.

It can be a constant or a variable or both.

A constant is a letter or symbol whose value is fixed always.

In the given question,

As, Seven is a single digit number therefore it is a fixed value which can not change. Thus it is clear that seven is a constant . Also, seven is a term and an expression as well , as it denotes the mathematical value.

Annie made mistake in her trigonometric ratios. The opposite side of the right triangle should be 6 cm not 8 cm.

A right angle triangle is a triangle that has one of its angles as 90 degrees. The sum of angles in a triangle is 180 degrees.

Annie tries to solve the angle ABC of the right triangle. The angle ABC can be found using trigonometric ratios as follows:

where

∅ = angle ABC

Therefore,

sin ∅ = opposite / hypotenuse

sin ∅ = 6 / 10

sin ∅ = 3 / 5

∅ = sin⁻¹ 0.6

∅ = 36.8698976458

∅ = 36.87 degrees

Therefore, she made mistake in her trigonometric ratios.

Step-by-step explanation:

It seems like you have provided a sequence of pairs of numbers. If I understand correctly, the first number in each pair is a position index, and the second number is a corresponding value.

To find an equation that fits this data, we can use regression analysis to try to find a mathematical function that closely approximates the pattern in the data.

Based on visual inspection of the data, it seems like there may be a roughly quadratic relationship between the position index and the corresponding value. We can try fitting a quadratic function of the form y = ax^2 + bx + c to the data using a regression tool or by solving for the coefficients manually.

Here are the steps to manually solve for the quadratic equation:

1. Choose three data points to substitute into the quadratic equation (x, y): (1, 50), (2, 56), and (3, 67).

2. Substitute each point into the quadratic equation to obtain three equations:

a + b + c = 50

4a + 2b + c = 56

9a + 3b + c = 67

3. Solve the system of equations to obtain values for a, b, and c. One way to do this is to subtract the first equation from the second to get an equation in terms of a and b only, and then do the same for the second and third equations. This gives us two equations:

3a + b = 6

5a + b = 11

Solving for b in terms of a using the first equation and substituting into the second equation gives:

5a + (3a + 6) = 11

8a = 5

a = 5/8

Substituting this value of a back into the first equation above gives:

3(5/8) + b = 6

b = 57/8

Finally, substituting a and b into any of the three original equations gives:

c = 37/8

Thus, we have found a quadratic equation that fits the data reasonably well:

y = (5/8)x^2 + (57/8)x + 37/8

Note that this is not necessarily the only equation that could fit the data, and there may be other equations that fit the data better or worse depending on the specific criteria used to evaluate the fit.

The diameter of the circle is approximately 60 inches.

To explain further, we can use the formula relating the central angle of a sector to the length of its intercepted arc. The formula states that the length of the intercepted arc (A) is equal to the radius (r) multiplied by the central angle (θ) in radians.

In this case, we are given the central angle (225 degrees) and the length of the intercepted arc (30π inches).

To find the diameter (d) of the circle, we need to find the radius (r) first. Since the length of the intercepted arc is equal to the radius multiplied by the central angle, we can set up the equation 30π = r * (225π/180). Simplifying this equation gives us r = 20 inches.

The diameter of the circle is twice the radius, so the diameter is equal to 2 * 20 inches, which is 40 inches. Therefore, the diameter of the circle is approximately 60 inches.

In summary, by using the formula for the relationship between central angle and intercepted arc length, we can determine the radius of the circle. Doubling the radius gives us the diameter, which is approximately 60 inches.

Step-by-step explanation:

Given that:

Diameter of the cylinder: d=1.6 cm

Apothem of the hexagon: a=2 cm

Assuming the thickness of the steel hex nut: t=2 cm

Volume of metal in the hex nut: V=?

\(V=V_p-V_c\)

\(\texttt {Volume of the prism}: V_p\\\\\texttt {Volume of the cylinder}: V_c\)

Prism:

\(V_p=Ab h\)

Ab=n L a / 2

Number of the sides: n=6

Side of the hexagon: L

Height of the prism: h=t=2 cm

Central angle in the hexagon: A=360°/n

A=360°/6

A=60°

\(\tan \frac{A}{2} =\frac{L}{2} / a\)

\(\tan \frac{60}{2} =\frac{L}{2} / 2cm\)

\(\tan 30 =\frac{L}{2} / 2cm\)

\(\frac{\sqrt{3} }{3} =\frac{\frac{L}{2} }{2}\)

\(2\frac{\sqrt{3} }{3} =\frac{L}{2}\)

\(L=4\frac{\sqrt{3} }{3}\)

\(Ab=n *L *\frac{a}{2}\)

\(Ab=6(4\frac{\sqrt{3} }{3} )(2cm)/2\)

Since PS = RS, the triangle PRS is isosceles. This means the angles SPR and SRP are congruent.

The interior angles of any triangle sum to 180° in measure. So we have

2 ∠SPR + 90° = 180°

2 ∠SPR = 90°

De Morgan's laws are two rules in formal logic that involve negating statements. The first law states that the negation of a conjunction (an "and" statement) is equivalent to the disjunction (an "or" statement) of the negations of the individual components.

The second law states that the negation of a disjunction is equivalent to the conjunction of the negations of the individual components.

Therefore, the negation of the original statement is "She does not make the bed, and I make the bed." This means that both she does not make the bed and I make the bed must be true in order for the negation to be true.

Answer:

Answer:

-1.5

Step-by-step explanation:

The gradient of a line can be found using the formula:

gradient = (y2 - y1) / (x2 - x1)

where (x1, y1) and (x2, y2) are the coordinates of two points on the line.

So for the line that passes through (3, 7) and (1, 10), the gradient can be found as:

gradient = (10 - 7) / (1 - 3)

gradient = 3 / -2

gradient = -1.5

So the gradient of the line that passes through (3, 7) and (1, 10) is -1.5.

Answer:

y = 4x - 7 (Answer C)

Step-by-step explanation:

First find the slope of this line.  Note that as we go from (2, 1) to (3, 5), x (the 'run') increases by 1 and y (the 'rise') increases by 4.  

Thus, the slope, m, is

m = rise / run = 4/1, or m = 4.

Apply the point-slope form of the equation of a straight line, since we now have both the slope and two points on the line:

y - k = m(x - h) becomes y - 1 = 4(x - 2)

Solving for y, we get:  y = 4x - 8 + 1, or y = 4x - 7 (Answer C)

So the unknown number is 120.
