Triangle LMN is an obtuse triangle with l = 6, n = 8.3, and m∠M = 132°. What is the area of ΔLMN?

Answers

Answer 1

The area of triangle LMN is 49.61 square units.

We have,

To find the area of triangle LMN.

Area = (1/2) x base x height

where the base and height are the sides of the triangle perpendicular to each other.

First, we need to find the length of side L.

We can use the Law of Cosines.

L² = M² + N² - 2MNcos(132°)

L² = 6² + 8.3² - 268.3cos(132°)

L² = 36 + 68.89 + 99.36

L² = 204.25

L = √204.25

L = 14.28

Now that we know the length of the base of the triangle, we can find the height by dropping a perpendicular from vertex M to side LN.

Since triangle LMN is obtuse, the perpendicular will fall outside of the triangle.

Let's call the foot of the perpendicular point P.

Since M∠M is 132°, we can find the measure of the acute angle ∠LMP:

M∠LMP = 180° - M∠M

M∠LMP = 180° - 132°

M∠LMP = 48°

We can use trigonometry to find the length of MP:

tan(48°) = h/6

h = 6 x tan(48°)

h = 6.93

The area of triangle LMN is:

Area = (1/2) x base x height

Area = (1/2) x 14.28 x 6.93

Area ≈ 49.61

Thus,

The area of triangle LMN is 49.61 square units.

Answers

The Perimeter of the given figure rectangle will be 60m. The correct option is 1.

Perimeter refers to the total length of the boundary of a two-dimensional shape or object. It is the distance around the edge of a shape. To find the perimeter of a shape, you add up the lengths of all its sides.

The perimeter of a rectangle is given by the formula:

P = 2(l + w)

where P is the perimeter, l is the length, and w is the width.

Using the values you provided, we can substitute them into the formula:

P = 2(18 + 12) = 2(30) = 60 meters

Therefore, the perimeter of the rectangle with a length of 18 meters and a height of 12 meters is 60 meters.

We can now use elimination to find x:

Answers

The number of unicycles, tandem bikes, and tricycles that IRVS Cycle Rental has are:

unicycles - 8 tandem bikes - 8 tricycles - 9

How to find the items the shop has ?

The relevant equations, ( assuming that unicycles as U, tandem bikes as T, and tricycles as R ) are:

U + T + 32 + R = 57

U + 2T + 2 x 32 + 3R = 115

U = T

Using substitution, we get:

U + 2T + 64 + 3R = 115

U + 2T + 3R = 51

U + 2U + 3R = 51

3U + 3R = 51

Solving gives:

2U + R = 25

U + R = 17

U = 8

Solving for R, we have :

8 + R = 17

R = 17 - 8

R = 9

Answers

There is a financial advantage of $ 1,187,520.

Incremental Costs and Revenues will be as follows

Increment in sales = 82,000 units × 40% = 32,800 units

and, Selling Price

= (32,800 units × $62 per unit)

= $ 2,033,600

Direct materials

= $ 7.50 × 32,800 units

= 246,000

Direct labor

= $ 9.00 × 32800

= $295,200

and, Variable manufacturing overhead

= 2.40 x 32800

= $78, 720

So, the contribution is

= 2,033,600 - (246000 + 285200 + 78720)

= 1,423,680

Now, Variable selling expenses

= 32800 x 3.7

How is the greatest common factor of 8x^5, 12x^3, and 20x^2 4x^2 when 2 does not go evenly into 5?

Answers

We can factor each of the given terms so that 4x^2 shows up

8x^5 = 4x^2*2x^3

12x^3 = 4x^2*3x

20x^2 = 4x^2*5

This shows how 4x^2 is the GCF of 8x^5, 12x^3, and 20x^2

-----------------

Here's how to find the GCF of terms involving variables.

First, find the GCF of the coefficients 8, 12 and 20.

List the prime factorizations

8 = 2*2*212 = 2*2*320 = 2*2*5

Then circle "2*2" since it is found in all three factorizations. Do not circle 3 because it's not found in 8 or 20. Do not circle 5 since it's not found in 8 or 12.

Therefore, the GCF of {8,12,20} is 2*2 = 4.

As for the variable terms, we look for the smallest exponent.

The exponents for x^5, x^3, x^2 are 5,3,2 in that order. The smallest exponent is 2, so x^2 is part of the GCF.

----------------

Summary:

We found the GCF of the coefficients was 4.

The GCF of the variable terms was x^2

That's how we arrive at the GCF of 4x^2

How to determine whether AB is a tangent

A tangent will obey Pythagorean triple hence we have that

AB = sqrt (676) = 26. hence AB is a tangent

AB = sqrt (185) = 13.6. hence AB is not a tangent

Length of arc

4. arc ST = 180 - arc RS = 180 - 100 = 80 degrees

Abi takes out a loan that gathers compound interest. The table below shows the value of the loan over time. a) What is the rate of interest per annum?

Start After 1 year After 2 years £2500.00 £2645.00 £2798.41​

Answers

As per the given percentage, the value of the loan 10 years after it starts is £4506.32.

We know the values of P and A for the first two years. So, we can use these values to find the value of r. Let's use the formula for the first year:

2645 = 2500(1 + r/1)¹ˣ¹

Simplifying the equation, we get:

1 + r = 2645/2500

1 + r = 1.058

r = 0.058 or 5.8%

Therefore, the interest rate per annum is 5.8% (to 1 decimal place).

Now, let's move on to finding the value of the loan after 10 years. We can use the same formula for compound interest, but we need to substitute the values of P, r, n, and t accordingly. Here's the formula:

A = P(1 + r/n)ⁿˣ

Where:

P = 2500

r = 0.058

n = 1 (as the interest is compounded annually)

x = 10

Substituting these values, we get:

A = 2500(1 + 0.058/1)¹ˣ¹⁰

A = 2500(1.058)¹⁰

A = 4506.32

Answers

Answer:

To find out how many 1 1/2 foot boards can be cut from a 12 foot long board, we need to divide the length of the board by the length of each board.

First, we need to convert 1 1/2 feet to an improper fraction.

1 1/2 = (2 x 1 + 1) / 2 = 3/2

So, each board is 3/2 feet long.

Next, we divide the length of the 12 foot long board by the length of each board:

12 / (3/2) = 12 x 2/3 = 24/3 = 8

Therefore, 8 boards of length 1 1/2 feet can be cut from a 12 foot long board.

The principal P is borrowed at a simple interest rate r for a period of time t. Find the loans future value A or the total amount due at time t
P= 5000
r=4.5%
t = 6 months

Answers

The future value or the total amount due at time t for the loan is $5112.50.

To find the future value or the total amount due at time t for a loan with a principal P, a simple interest rate r, and a period of time t, we can use the formula for calculating simple interest;

A=P + (P × r × t)

where; A = future value or total amount due at time t

P = principal amount

r = simple interest rate

t = time period (in years)

Given the values; P = $5000

r = 4.5% (or 0.045 as a decimal)

t = 6 months (or 0.5 years)

We can substitute these values into the formula and calculate the future value;

A = 5000 + (5000 × 0.045 × 0.5)

A = 5000 + 112.5

A = $5112.50

A clothing business finds there is a linear relationship between the number of shirts, n, it can sell and the price, p, it can charge per shirt. Historical data show that 2,000 shirts can be sold at a price of $30, while 3,000 shirts can be sold at a price of $25. Find a linear function in the form p(n) = mn + b, note this is the same as y = mx + b, where the slope and variable have very specific values, specified by the application, that gives the price p they can charge for n shirts 3.4 Modeling with Linear Functions: 7. Explain how to find the output variable in a word problem that uses a linear function.
