Triangles RST and XYZ are drawn below. If RS= 6, ST=14, XY = 9, YZ=21, and ZSZY, is ARST similar to AXYZ? Justify your answer.

The value of a and b are a=8 and b=6 respectively.

factorization is the method of breaking a number into smaller numbers that multiplied together will give that original form.

We are given the expression as

3/(5x) + 1/(x+2)

We have to multiply 3 by (x+2) and 1 by (5x)

3(x+2) = 3x+2 and 1(5x)= 5x

Now we have

3x+6/(5x)(x+2)

5x/(5x)(x+2)

Now adding the numerators gives us

8x+6/(5x)(x+2)

Therefore a=8 and b=6

Answer:

$2091 (exact answer is $2090.80)

Step-by-step explanation:

2050 × 6.8% = 6.8

So, interest will add an extra $6.80 to his account

6.8 × 6 = 40.8

So, after 6 years, interest will make him an additional $40.80.

Add 40.80 to his original amount of money.

2050 + 40.8 = 2090.80

Round it up to the nearest dollar.

Answer:

The area of the polygon is 624.5 square feet.

Step-by-step explanation:

The total area of the figure ([tex]A[/tex]), in square feet, is the sum of the areas of two triangles and a rectangle, that is:

[tex]A = A_{I}+A_{II}+A_{III}[/tex] (1)

Where:

[tex]A_{I}[/tex] - Area of the big triangle, in square feet.

[tex]A_{II}[/tex] - Area of the small triangle, in square feet.

[tex]A_{III}[/tex] - Area of the rectangle, in square feet.

Then, we expand the formula by using all dimensions presented in the image attached:

[tex]A = \frac{1}{2}\cdot (25\,ft)\cdot (33\,ft-8\,ft) + \frac{1}{2}\cdot (8\,ft)\cdot (43\,ft-35\,ft) + (35\,ft)\cdot (8\,ft)[/tex]

[tex]A = 624.5\,ft^{2}[/tex]

The area of the polygon is 624.5 square feet.

Answer:

I believe it is 54.40$

Step-by-step explanation:

I think weird. so

68 divided by 5 which will give you 20%(13.6) then multiply by 4 which is 80%(54.4)

Answer:

Sale price = $13.6

Step-by-step explanation:

The 80% cost of the jacket is,

→ (68/100) × 80

→ 0.68 × 80

→ $54.4

Now the sale price will be,

→ 100% - 80%

→ 68 - 54.4

→ $13.6

Hence, sale price is $13.6.
