the measures of the angles in a triangle are in an extended ratio of 1:3:5. Find the measures of the 3 angles. ​

Answer:

B

Step-by-step explanation:

So for some reason the person didn't put the equations... I had the same question so here they are.

A.x^2 – 8x = 24

x2 – 8x + 4 = 24 + 4

B.x^2 – 8x = 24

x2 – 8x + 16 = 24 + 16

C.x^2 – 8x = 24

x2 – 8x + 64 = 24 + 64

D.x^2 – 8x = 24

x2 – 8x + 144 = 24 + 144

Good luck!

The quadratic equation can be solved by completing square method. The steps to solve the given equation are explained in detail.

The general form of a quadratic equation is given as ax^2 + bx + c = 0.

Here, a ≠ 0 and b and c are integers.

The degree of a quadratic equation is 2.

The given equation is,

x^2 - 8x -24 = 0

To solve this equation by completing square method, it has to be transformed into the form of (a + b)^2.

The steps for this method are given as follows,

(i) Find the coefficient of x^2. The square root of the this coefficient is the value of a.  

(ii) Find the term containing non-square part. In the given case it is -8x.

(iii) Compare the coefficient of this term with 2ab. it gives,

2ab = -8

=> 2 × 1 × b = -8

=> b = -4

(iv) Write the equation in the form of a^2 + 2ab + b^2 leaving the remaining term as it is. For the given equation it can be written as,

x^2 - 8x + 4^2 - 40 = 0

=> x^2 - 8x + 4^2 = 40

(v) Now, write the equation in terms of (a +b)^2 and get the solution. In this case it is written as,

(x - 4)^2 = 40

=> x - 4 = ±√40

=> x = 4 ±√40

Im supposing this is a rectangle with length of 20 and width of 24, so... area is equal to lenth by width, so A=L*W or A=20*24 so the area is 480 square feet

Answer: A = 27 squared units

Step-by-step explanation:

Area = 3 x 9 and you use square units when referring to area

Answer:

the answer is 27 ( i don't known if its squared or unit-sorry)

Answer

Option 2, 4 and 5 :)

Step-by-step explanation:

Option 2 is already simplified to 20x + 30y

Option 4,

10*2x=20x and 10*3y= 30y so option 4 also simplifies to 20x + 30y

Next Option 5, 10*2x= 20x and 10*3y=30y. So it's also 20x + 30y

Answer:

b. PHP 31,250.00

Step-by-step explanation:

Simple interest = principal × rate × time

Principal = PHP 25,000

Rate = 2.5%

Time = 10 years

Simple interest = principal × rate × time

= PHP 25,000 × 2.5% × 10

= 25,000 × 0.025 × 10

= 6,250

Simple interest = PHP 6,250

Investment after 10 years = principal + simple interest

= PHP 25,000 + PHP 6,250

= PHP 31,250

Investment after 10 years = PHP 31,250

-2(7) + -2(5g)

Step-by-step explanation:

Using the distributive property we can confirm that:

-2(7) + -2(5g) = -2(7+5g)

Answer:

−14−10g

Step-by-step explanation:

First, solve the product:

-2 ⋅ 7 - 2 ⋅ 5g

Multiply -2 times 7 to -14.

So, the equivalent expression would be:

-14 - 2 ⋅ 5g = -14 - 10g

We have to find the largest fraction in each group.

a). [tex]$\frac{5}{6}$[/tex] and [tex]$\frac{29}{36}$[/tex]

    [tex]$\frac{5}{6}$[/tex]  →  when we divide the number 5 with 6, we get 0.833

    [tex]$\frac{29}{36}$[/tex] → when we divide 29 by 36, we get the value 0.805

Therefore, in this group, [tex]$\frac{5}{6}$[/tex] is the largest fraction.

b).  [tex]$\frac{5}{12}$[/tex] and [tex]$\frac{3}{8}$[/tex]

     [tex]$\frac{5}{12}$[/tex]  →  when we divide the number 5 with 12, we get 0.416

    [tex]$\frac{3}{8}$[/tex] → when we divide 3 by 8, we get the value 0.375

Therefore, in this group, [tex]$\frac{5}{12}$[/tex] is the largest fraction.

c).  [tex]$\frac{2}{5}$[/tex] and [tex]$\frac{19}{45}$[/tex]

     [tex]$\frac{2}{5}$[/tex] →  when we divide the number 2 with 5, we get 0.40

    [tex]$\frac{19}{45}$[/tex] → when we divide 19 by 45, we get the value 0.42

Therefore, in this group, [tex]$\frac{19}{45}$[/tex] is the largest fraction.

d).  [tex]$\frac{5}{7}$[/tex], [tex]$\frac{13}{14}$[/tex] and  [tex]$\frac{19}{21}$[/tex]

      [tex]$\frac{5}{7}$[/tex] →  when we divide the number 5 with 7, we get 0.714

    [tex]$\frac{13}{14}$[/tex] → when we divide 13 by 14, we get the value 0.928

    [tex]$\frac{19}{21}$[/tex]  → when we divide 19 by 21, we get the value 0.904

Therefore, in this group, [tex]$\frac{13}{14}$[/tex]  is the largest fraction.

Answer:

[tex]A=2833.71\ cm^2[/tex]

Step-by-step explanation:

Given that,

The height of the cylinder, h = 30 cm

The radius of the cylinder, r = 11 cm

We need to find the total surface area of the cylinder. The formula for the total surface area of the cylinder is given by :

[tex]A=2\pi rh+2\pi r^2\\\\A=2\pi \times 11\times 30+2\pi \times (11)^2\\\\A=2833.71\ cm^2[/tex]

So, the total surface area of the cylinder is [tex]2833.71\ cm^2[/tex].

The equivalent value of the expressions are solved by the exponents

When you raise a quotient to a power you raise both the numerator and the denominator to the power. When you raise a number to a zero power you'll always get 1. Negative exponents are the reciprocals of the positive exponents.

The different Laws of exponents are:

mᵃ×mᵇ = mᵃ⁺ᵇ

mᵃ / mᵇ = mᵃ⁻ᵇ

( mᵃ )ᵇ = mᵃᵇ

mᵃ / nᵃ = ( m / n )ᵃ

m⁰ = 1

m⁻ᵃ = ( 1 / mᵃ )

Given data ,

Let the exponential equation be represented as A

Now , the value of A is

A = 25ˣ

On simplifying , we get

A = ( 5 . 5 )ˣ

A = ( 25 )ˣ

And , A = 5ˣ . 5ˣ

From the laws of exponents , we get

mᵃ×mᵇ = mᵃ⁺ᵇ

A = 5²ˣ

A = 25ˣ

Hence , the expressions are ( 5 . 5 )ˣ = 5²ˣ = 5ˣ . 5ˣ = 25ˣ

Answer:

3x + 75 + 90 = 180

x = 5°

Step-by-step explanation:

3x + 75° + 90° = 180°( being sum of angles of triangle)

3x = 180° - 75°- 90°

3x = 15°

x = 15° / 3

x = 5°
