Triangle ABC is similar to triangle DEFwhich proportion can be used to find the length of DE in centimeters?A. 4/3 = DE/9B. 5/15 = DE/4C. 4/DE = 9/3D. 9/DE = 3/5

The rate of return of the 12 shares purchased by A is 72.72%.

Here, we are given that A purchases 12 shares at $22 per share.

So the cost price of 12 shares will be = 12 × 22

= 264

A sold these shares at $465.

The commission on sale = $9.

Thus, the total cost of the shares will be = 264 + 9

= $273

Hence, the total profit of A will be-

465 - 273

= 192

The rate of return is calculated as-

Rate of return = profit/cost price × 100

Thus, here-

Rate of return = 192/264 × 100

= 0.7272 × 100

= 72.72%

Thus, the rate of return on these 12 shares purchased by A is 72.72%.

One needs to sell $6750 worth of goods to make the straight commission be at least good to the secondary offer

Straight offer = 6% commission on the sales

Second offer = $270 + 2% of the sales

For the straight offer to be competitive with the second offer it should be able to cover the fixed income of $270

Let x be the sales made in the week

Formulating the equation we get the following:

6% of x = 270 + 2% of x

6/100x = 270 + 2/100x

4/100x = 270

x = 6750

So, for sales up to $6750, the second job offer is good, while for sales more than $6750 the first job offer is good

The exact value of indicated trigonometric function, sin θ is -0.92

The sine relation is the ratio of the height to the hypotenuse. Meanwhile, the cosine relation is the ratio of the base to the hypotenuse.

The relation of sine and cosine is given as follows:

[tex]\sin \theta=\pm\sqrt{1-\cos^2\theta}[/tex]

It is given that cos θ = (2/5)

So, the sine value can be obtained from the given value.

[tex]\sin \theta=\pm\sqrt{1-\cos^2\theta}\\=\pm\sqrt{1-(2/5)^2}\\=\pm\sqrt{21}/5\\ =-0.92[/tex]

So, the sine value for the given cosine value is - [tex]\sqrt{21}/5[/tex] or -0.92.

Note that we omitted the positive value because it is given that the tangent value is negative, so the angle lies in the fourth quadrant, where the sine value is also negative.

The value of sin t = sin 135° = 1/√2

The trigonometric functions are real functions that connect the angle of a right-angled triangle to the ratios of its two side lengths. They are also known as circular functions, angle functions, or goniometric functions[1][2]. They are extensively employed in all fields of geometry-related study, including geodesy, solid mechanics, celestial mechanics, and many others.

Given; tan t = 1

And the given condition is π/2 < t < 3π/ 2

this mean t lies in the 2nd quadrant because the value of t lies between 90 and 270 degrees.

This means tan t = tan (90 + 45)= cot 45 = 1

thus t = 235 degree

And thus sin t = sin 135 ° = sin (90+ 45) = cos 45 ° =  1/ √2

The linear equation that passes through the point (-6, 5) and B is the point (-2,-3) is:

y = -2x - 7

A general linear equation is:

y = a*x + b

Where a is the slope and b is the y-intercept.

If the line passes through two points (x₁, y₁) and (x₂, y₂) then the slope is:

s = (y₂ - y₁)/(x₂ - x₁)

In this case, we have the points (-6, 5) and (-2,-3), then the slope is:

s = (-3 - 5)/(-2 + 6) = -8/4 = -2

Then we have:

y = -2*x + c

To find the value of the constant we use one of the points, I will use (-2, -3) to get:

-3 = -2*(-2) + c

-3 = 4 + c

1. 3x-18> 12 , add 18 on both sides:

3x - 18 + 18 > 12 + 18

3x > 30

2. Divide both sides by 3:

The total interest earned by Rudy on the principal is $9000

Amount in Rudy's saving account = $90,000

Interest rate per year = 10%

The formula for simple interest is given:

A loan or deposit's principal amount serves as the foundation for simple interest. Compound interest, on the other hand, is calculated based on both the initial principal and the interest that is added to it each period.

Simple interest = P*R*T/100

where P = principal amount invested

R = rate of interest

T = time in years

Substituting the values in the formula we get:

Simple interest = 90000*10*1/100

The value of x is 6, then the value of JK is 83, KL is 83 and JL is 83.

A triangle is a polygon that has three sides and three vertices. It is one of the basic figures in geometry.

An equilateral triangle is a shape with three sides that have an equal measure of side length.

The 3 sides of triangle JKL are equal to each other, therefore we can equate any of the two sides together to find the unknown variable called x.

So, JK = KL

JK = 13x + 5

KL + 17x - 19

13x + 5 = 17x - 19

Collect like terms;

17x - 13x = 19 + 5

4x = 24

x = 24/4

x = 6

We can now proceed to find the sides;

JK = 13x + 5

13 x 6 + 5

= 78 + 5

= 83

JK = 83

KL = 17x - 19

= 17 x 6 - 19

= 102 - 19

= 83

KL = 83

JL= 8x + 35​

= 8 x 6 + 35

Step 1: We have two triangles with the following information:

• Upper Triangle has two known angles: 29 and 52 degrees

• Lower Triangle has one known angle: 33 degrees and two unknown: x and the third angle

Step 2: Let's find the third angle of the upper triangle, as folllows:

Third angle = 180 - 29 - 52

Third angle = 99

Step 3: Now we can see that the angle we just found on Step 2 is a congruent angle with the third angle from the lower triangle, which means they are equal.

Therefore, we know two angles of the lower triangle:

99 and 33

The smallest whole numbers that makes the statement true are:

(a) 41 - 9 ≡ 2 (mod 5)

(b) 17 + 8 ≡ 4 (mod 7)

Let a, b and m be integers. Then a is said to be congruent to b modulo m if m divided a-b. That is,

a ≡ b(mod m) if and only if m divided a-b.

Also here, if b is the smallest integer satisfying this relation, then b is the remainder when a is divided by m.

(a) So for  41 - 9 ≡   (mod 5)

⇒ 32 ≡    (mod 5)

The smallest whole number satisfying this congruence is the remainder when 32 is divided by 5 which is 2.

That is,  41 - 9 ≡ 2 (mod 5)

(b) Similarly for 17 + 8 ≡   (mod 7)

⇒ 25 ≡   (mod 7)

The smallest whole number which makes this statement true is the remainder when 25 is divided by 7, which is 4.
