What is 344 divided by 9

Answer:

31,5

Step-by-step explanation:

=7*3+(7*3)/2

Answer:

length x width = area

7 x 3 = 21 so the area of the rectangle is 21

divide 7 by 2 so we can find the length of each triangle. 7 / 2 = 3.5

length (or base) x height / 2 = area of triangle

3.5 x 3 = 10.5

You do not have to divide by two because there are two triangles

10.5 + 21 = 31.5 so the area is 31.5

Answer: A. x < 2

Step-by-step explanation:

         We will isolate the variable with inverse operations.

Given:

  3x – 2 < 4

Add 2 to both sides of the equation:

  3x < 6

Divide both sides of the equation by 3:

  x < 2

        A. x < 2

A relationship between two expressions or values that is not equal to one another is referred to as "inequality" in mathematics.

A mathematical phrase, rule, or law that establishes the link between an independent variable and a dependent variable (the dependent variable). In mathematics, functions exist everywhere, and they are crucial for constructing physical links in the sciences.

Isolate the variable on one side of the inequality and place all other constants on the other. To achieve this, alter the inequality by performing opposing procedures.

First, multiply each side by two to isolate the x.

Any action you take toward one side must also be taken toward the other.

Simplifying Y + -10 = 14

rearranging the phrases

-10 + Y = 14

Solving -10 + Y = 14 fixing the 'Y' variable.

All terms that contain Y should be shifted to the left, and all other terms to the right.

To either side of the equation, add "10."

-10 + 10 + Y = 14 + 10

-10 + 10 = 0 0 + Y = 14 + 10 Y = 14 + 10 combining similar terms 14 + 10 = 24 Y = 24 Simultaneously,

Y = 24

Therefore the value of y is 24

and the second statement gives

Hence, we have a system of equations with two unknowns and 2 equations which we need to solve in order to answer our question.

Let us solve for c in the first equation. Doing this gives

putting that into the second equation gives

With the value of f in hand, we put it into the first equation and solve for c:

Hence, the price of citron is 8 units and the price of the fragrant wood apples is 5 units.

Answer:

D. \(10^{\circ}\)

Step-by-step explanation:

Let the measure of minor arc \(AE\) be \(\alpha\) and the measure of minor arc \(BD\) be \(\beta\).

Using the secant-secant theorem, \(\frac{\alpha-\beta}{2}=32 \implies \alpha-\beta=64^{\circ}\).

By the inscribed angle theorem, \(\alpha=84^{\circ}\).

Thus, \(\beta=20^{\circ}\).

By the inscribed angle theorem, \(x=10^{\circ}\).

The correct proof of the equation is cos3θ =cos(2θ + θ) =  cos²θ - 3cosθsin²θ (Proved)

Given the trigonometry identity below:

cos3∅=cos²∅-3cos∅sin²∅

We are to prove that both sides of the equation are equal.

cos 3θ = cos(2θ + θ)

Using the double angle formula for cosine, we can expand the first term:

cos(2θ + θ) = cos2θ cos θ - sin2θ sinθ

Since cos2θ = cos²θ - sin²θ

cos(2θ + θ) =  cos²θ - sin²θ - 2cosθsinθsinθ

cos(2θ + θ) = cos²θ - sin²θ - 2cosθsin²θ

On simplifying, we can see that;

cos3θ =cos(2θ + θ) =  cos²θ - 3cosθsin²θ (Proved)

The depth of the aquarium is approximately 4 feet when rounded to the nearest whole number (since 3.64 is closer to 4 than it is to 3 when rounded to the nearest whole number).

To calculate the depth of the aquarium, we need to use the formula for volume of a rectangular prism,

which is V = lwh where V is the volume, l is the length, w is the width, and h is the height (or depth, in this case).

Given that the aquarium holds 11.35 cubic feet of water, the volume of the aquarium can be represented by V = 11.35 cubic feet.We are also given that the length of the aquarium is 2.6 feet and the width is 1.1 feet.

Substituting these values into the formula for volume,

we get:11.35 = 2.6 × 1.1 × h

Simplifying this expression:

11.35 = 2.86h

Dividing both sides by 2.6 × 1.1,

we get:h ≈ 3.64 feet (rounded to two decimal places)

No

Step-by-step explanation:

A:  30% of $45 means we must multiply 0.30 and 45. $45 x 0.30 = $13.50 is the markup. Next, add $13.50 to $45 for a total of $58.50 to get the total amount the store will charge with the markup.  

B:   X = price the STORE pays for instr.

130% X   = $ 104

X = 104/(130%) = 104/1.3 = $ 80

According to the concept of algebraic expression and arithmetic, the correct answers are A) Number of adults = N - 25. B) Number of adults when N = 124: 124 - 25 = 99

A) Let's denote the number of children as N. Since there are 25 fewer adults than children, the number of adults can be expressed as N - 25.

B) If there are 124 children, we substitute N with 124 in the expression from part A. Thus, the number of adults would be 124 - 25 = 99.

To arrive at these answers, we used the given information that there are "N" children and 25 fewer adults than children. By substituting the value of N, we determined the number of adults in terms of N and then calculated the specific number of adults when N is equal to 124.

Note: The given question is incomplete. The complete question is:

Some adults and children are watching a musical. there are 'N' number of children. There are 25 fewer adults than children.

Answer:

Step-by-step explanation: C. 2x+3=1/2(4x+2)+2 hopes this helps:)

The equations that are identities are option B x – 4(x + 1) = –3(x + 1) + 1 and option C 2x + 3 = 1/2(4x + 2) + 2.

To check which equation is an identity, we need to simplify each equation and see if it is true for all values of x.

A. 3(x – 1) = x + 2(x + 1) + 1

Expanding the right side:
3(x – 1) = x + 2x + 2 + 1
3x – 3 = 3x + 3-3 = 3

This is a contradiction and cannot be true for any value of x. Therefore, option A is not an identity.

B. x – 4(x + 1) = –3(x + 1) + 1
Expanding both sides:
x – 4x – 4 = –3x – 3 + 1
-3x – 3 = -3x – 3

This equation simplifies to -3x - 3 = -3x - 3, which is true for all values of x. Therefore, option B is an identity.

Similarly,

Option C is an identity.

Option D is not an identity.

A common denominator is a shared multiple of the denominators of the fractions involved when adding or subtracting fractions. It enables fraction comparison and addition/subtraction.

Simplification is the process of reducing a fraction to its simplest form by dividing the numerator and denominator by their greatest common divisor. This is done to represent fractions in the simplest terms viable.

Conversion: The process of transferring a fraction from one form to another while retaining its equal value is known as conversion. Finding a common denominator or expressing a fraction in terms of a specified unit or fraction may be required.

Fraction Addition/Subtraction: When adding or subtracting fractions, a common denominator is required. This entails determining a common multiple of

To rewrite the expression 3 + 1/5 + 2/3 using fifteenths as the common denominator, we need to find a common denominator for 5 and 3, which is 15 (since 5 and 3 are both factors of 15).

First, let's convert the fractions 1/5 and 2/3 to fifteenths:

\((\frac{1}{5})(\frac{3}{3}) = \frac{3}{15}\)

\((\frac{2}{3})(\frac{5}{5}) = \frac{10}{15}\)

Now we can rewrite the expression using the common denominator:

\(3 + \frac{3}{15}+\frac{10}{15}\)

Using Trigonometric ratios, the value of missing angle is 60.45°.

There are six popular trigonometric functions for an angle. Sine (sin), cosine (cos), tangent (tan), cotangent (cot), secant (sec), and cosecant are their respective names and acronyms (csc).

If we draw an imaginary line dividing the given triangle in 2 equal parts,

we will get 2 right angled triangles.

So, using trigonometric ratios,

Sin θ = Perpendicular / hypotenuse

⇒ Sin 70 ° = perpendicular / 14

⇒ 0.94 = perpendicular / 14

⇒ perpendicular = 0.94 × 14

⇒ perpendicular = 13.16

Now the other right angled triangle is

Sin θ = Perpendicular / hypotenuse

⇒ Sin θ = perpendicular / 15

⇒  Sin θ = 13.16 / 15

⇒ θ = sin⁻¹(13.16 / 15)

⇒ θ = sin⁻¹(0.87)

⇒ θ = 60.45
