Answer:

A. The third angle measures 30*

B. Two sides have the same length

The statement first “The third angle measures 30°” and statement second “Two sides have the same length.” are correct.

The triangle can be defined as a three-sided polygon in geometry, and it consists of three vertices and three edges. The sum of all the angles inside the triangle is 180°.

We have:

Triangle with angle measures of 30° and 120°

Third angle measure = 180–30 – 120 = 30 degree

Two angles measures are same, and two sides have the same length.

Thus, the statement first “The third angle measures 30°” and statement second “Two sides have the same length.” are correct.

Answer:

Identity (a) can be re-written as

[tex]sec x\ cosec x - cot x = tan x[/tex]

which we already proven in another question, while for idenity (b)

[tex](A)\frac 1 {sin x} -sin x = cos x \frac{cos x}{sin x}\\\\(B)\frac {1-sin^2x}{sin x} = \frac {cos^2x} {sin x} \\\\(C) \frac {cos^2x}{sin x} =\frac {cos^2x} {sin x}[/tex]

step A is simply expressing each function in terms of sine and cosine.

step B is adding the terms on the LHS while multiplying the one on RHS.

step C is replacing the term on the numerator with the equivalent from the pithagorean identity [tex]cos^2x + sin^2x = 1[/tex]

The modelled situation in a linear format is y = [tex]-\frac{5}{2}x+239[/tex]

The cost of the ticket if Marcus buys it 3 days before his departure is $231.5

y = mx + b

where

m = slope

b = y-intercept

b = 239

Therefore, let's model the situation to a linear equation.

y = mx + 239

using (20, 189)

189 = 20m + 239

189 - 239 = 20m

-50 = 20m

m = [tex]-\frac{5}{2}[/tex]

Therefore,

y = [tex]-\frac{5}{2}x +239[/tex]

where

x = The day before departure

y = cost of ticket

To determine the cost of the ticket if Marcus buys it 3 days before his departure.

y = [tex]-\frac{5}{2}(3)+239[/tex]

y = -7.5 + 239

y = $231.5

Addison needs to cut $45 from Food/Clothes and $41 from Entertainment, to pay the revised monthly payment.

It is given that

Addison has a balance of $3,450 on her credit card.

APR = 18%

Current monthly payment = $86.25

She wants to choose a monthly payment for 24 months.

So for 24 months,

A revised monthly payment using the formula,

[tex]M = \frac{P.\frac{R}{12}. (1+\frac{R}{12} )^N }{(1+\frac{R}{12})N -1}[/tex]

R = 0.18

P = 3450

N = 24

Revised montly payment M = $172.24

Current monthly payment = $86.25

Length of AD in the given figure is 12 cm

Answer:

In total, Esme will need to purchase at minimum TWELVE (12) pieces of fence in order to encompass her entire rectangular garden.

Step-by-step explanation:

Let us start off by isolating each of the two different length sides, and figure out which fence pieces can be used to it off.

For the three meter (3 m) side, we could utilize the following THREE (3) pieces...

Adding up those pieces provides us with our desired garden side length...

(1 × 1.8 m) + (2 × 0.6 m) = 3.0 m!

For the six meter (6 m) side, we could utilize the following THREE (3) pieces...

Adding up those pieces provides us with our desired garden side length...

(1 × 1.8 m) + (2 × 2.1 m) = 6.0 m!

We ought to not forget about the opposite sides of the aforementioned, to make up the four sides of the rectangle! In short, we double the number of pieces that we currently have...

In the end, the smallest number of pieces of fence that Esme will need to buy is TWELVE (12), consisting of the following pieces:

a pair of jenas that sell for $49

rate of tax is 6%

cost of that jeans is ?

Let the cost of jeans = x

through question

or, $49 = X + X×6%

or,$49 = X + X×6/100

or, $49 = 106X/100

or, $4900 = 106X

or, X = $4900/106

: X = $46.226

thus ; the cost of jeans is $46.226

Answer:

51.94

Step-by-step explanation:

6% of 49 is 2.94. 49 + 2.94 = 51.94

Step-by-step explanation:

Answer:

Number of large oranges: x

Number of small oranges: y

y < 6

x + y <= 10

The girl can buy a minimum of 3 oranges (either 3 large or 3 small) and a maximum of 10 oranges (a combination of large and small).

Let's represent the number of large oranges as "L" and the number of small oranges as "S."

From the given information, we have the following conditions:

At least three but fewer than nine large oranges: 3 ≤ L < 9

Fewer than six small oranges: S < 6

The maximum number of oranges she needs to buy is 10: L + S ≤ 10

Now, let's consider the possible combinations of L and S that satisfy these conditions:

L = 3, S = 0 (Total oranges = 3)

L = 4, S = 0 (Total oranges = 4)

L = 5, S = 0 (Total oranges = 5)

L = 6, S = 0 (Total oranges = 6)

L = 7, S = 0 (Total oranges = 7)

L = 8, S = 0 (Total oranges = 8)

L = 3, S = 1 (Total oranges = 4)

L = 4, S = 1 (Total oranges = 5)

L = 5, S = 1 (Total oranges = 6)

L = 3, S = 2 (Total oranges = 5)

L = 4, S = 2 (Total oranges = 6)

L = 3, S = 3 (Total oranges = 6)

As you can see, these are all the possible combinations of L and S that satisfy the given conditions. The girl can buy a minimum of 3 oranges (either 3 large or 3 small) and a maximum of 10 oranges (a combination of large and small).

Step-by-step explanation:

To be divisible by five, the number must end with a zero or a five, and forty-five is the only number that meets these conditions. Technically, all the numbers are divisible by five, but 83, 94, and 99 divided by five would equal a whole number with a decimal, meaning the only option that equals a whole number is forty-five (45).

Answer:

yes

Step-by-step explanation:

30% of 42 is 12.60 so 42.00 +12.60= 54.60

and 25% of 54.60 is 13.65 so 54.60 + 13.65 = 68.25

so the Original price is $68.25

The original price of the phone case is $93.33

Discounting is the process of determining the present value of a payment or a stream of payments that is to be received in the future.

Given that, the phone case, is marked down 30%, and we have a 25% off coupon, paid $42.00, for this in whole, we are asked to find the original price,

Let the original price be x,

Therefore,

x - (30% of x + 25% of x) = 42

x - (30/100 · x + 25/100 · x) = 42

x - (0.3x + .25x) = 42

x - 0.55x = 42

0.45x = 42

x = 93.33

Hence, the original price of the phone case is $93.33

The area of the shaded rectangle is 18 square units.

The shaded region is the framed rectangle, and the white part is the frame.

We know that the frame is 2 units wide, and the measure of the rectangle and the frame are:

Now, if we remove the frame, we will remove 2*2 units = 4 units for each measure (because for each measure we have the frame in both sides).

So the measures for the shaded rectangle are:

And the area of a rectangle is given by the product between the width and length, then we have:

A = (3 units)*(6 units) = 18 square units.
