Two angles are supplementary one angle is 2/3 the measure of the other one find both angles

Answers

Answer:

The measures are 108 deg and 72 deg.

Step-by-step explanation:

The larger angle has measure x.

The smaller angle has measure (2/3)x.

They are supplementary, so the sum of their measures is 180 degrees.

x + (2/3)x = 180

(3/3)x + (2/3)x = 180

(5/3)x = 180

(3/5) * (5/3)x = (3/5) * 180

x = 108

(2/3)x = 2/3 * 108 = 72

Answer: The measures are 108 deg and 72 deg.

Find the percentage of: 21% of 18 use a set of fraction operations method to find the percentage.

Answers

Answer:

4.8%

Step-by-step explanation:

21% of 18

following the BODMAS rule, OF means multiplication

and also this sign% always means 100

so,it will be  21/100 * 18/1

this a laptop so i cant put it in a fraction way.....okay

this is how it shows...21/100 * 18/1

lets divide....

21/100 * 18/1

we will use 2 to divide

2 in 100=50

2 in 18=9

so it will be 21/50 * 9/1

nothing can divide so we will multiply

21*9/50*1

189/50=3.78≈4.8%

A square window in Miranda's house has an area of 255 in2 (squared). What is the perimeter of the window?

Answers

Answer:

If you meant the area was 255 in²:

Perimeter is [tex]4\sqrt{255}[/tex], or around 63.89 in.

If you meant that the area was 225 in²:

Perimeter is 60 in

Step-by-step explanation:

If you meant the area was 255 in²:

If we have a square with an area of 255 in², then it's side length will be [tex]\sqrt{255}[/tex] inches long, since the area of a square is [tex]l^2[/tex], where l is the length.

Since [tex]\sqrt{255}[/tex] doesn't return a rational number, we'll leave it as [tex]\sqrt{255}[/tex].

Now that we know the side length, the perimeter of a square is represented as [tex]4l[/tex], where l is the length.

We know the length is [tex]\sqrt{255}[/tex], so we can multiply this by 4.

[tex]4\sqrt{255}[/tex]. This is the simplest it gets.

If you meant the area was 225 in²:

Following the same concept as again:

Length: [tex]\sqrt{225} = 15[/tex]

Perimeter: [tex]4\cdot15=60[/tex] in

Hope this helped!

Answer:

P = 63.87 in

Step-by-step explanation:

area of a square window = 255 in²

find perimeter of the window.

A = s²

255 = s²

s = 15.97 in.

perimeter = 4 * s

P = 4 (15.97)

P = 63.87 in

The upper-left coordinates on a rectangle are (-5, 6)(−5,6)left parenthesis, minus, 5, comma, 6, right parenthesis, and the upper-right coordinates are (-2, 6)(−2,6)left parenthesis, minus, 2, comma, 6, right parenthesis. The rectangle has a perimeter of 16units.

Answers

Answer:

Step-by-step explanation:

The question is incomplete. Here is the complete question.

The upper-left coordinates on a rectangle are (−5,6) and the upper-right coordinates are (−2,6). The rectangle has a perimeter of 16units. Draw the rectangle on the coordinate plane below.

If the coordinates of the top of the triangle (breadth) is  (−5,6) and  (−2,6), we can calculate the breadth of the rectangle by taking the difference between the two points using the formula:

D = √(y₂-y₁)²+(x₂-x₁)²

Given x₁ = -5, y₁= 6, x₂ = -2 and y₂ = 6

D = √(6-6)²+(-2-(-5))²

D = √0²+3²

D = √9

D = 3 units

Breadth = 3 units

Given the Perimeter to be 16 units and the formula for calculating the perimeter of rectangle t be P = 2(L+B), we can get the length of the rectangle.

16 = 2(3+L)

16 = 6+2L

16-6 = 2L

2L = 10

L = 10/2

L = 5 units.

Hence the length of the rectangle is 5 units and the breadth is 3 units. Find the diagram in the attachment.

At present the sum of Geetha's age and her daughter's age is 44 years. After 2 years, Geetha's age will be three times that of her daughter's age. Find their present ages.

Answers

Answer:

Geetha is 32.5 years old

her daughter is 11.5 years old

Step-by-step explanation:

sum of their ages is 44 years

G + D = 44

in two years, Geetha's age is 3 times her daughters age. (to find present age, subtract 2)

G = 3D - 2

substitute

(3D - 2) + D = 44

combine like terms

4D - 2 = 46

4D = 46

D = 11.5

plug in D to either equation

G + (11.5) = 44

G = 32.5

G = 3(11.5) - 2

G = 32.5

At a corner bakery, 6 croissants and 3 cups of coffee costs $25.95. An order of croissants and 6 cups of coffee costs $26.70. What is the cost of an order of 1 croissants and 1 cup of coffee?

Answers

Answer:

$6.36

Step-by-step explanation:

this is a system of equations problem. There are two main methods for this type of problem: elimination and substitution(I used both here). A-croissants, B-coffee.

The cost of an order of 1 croissant is $2.3 and 1 cup of coffee is $4.05.

We need to form the system of equations for the given statement.

What is the system of equations?

In mathematics, a set of simultaneous equations, also known as a system of equations or an equation system, is a finite set of equations for which common solutions are sought.

Let the cost of croissants be x and the cost of cups of coffee be y.

6 croissants and 3 cups of coffee costs $25.95

6x+3y=25.95-----(1)

1 croissant and 6 cups of coffee cost $26.70

x+6y=26.70-----(2)

(6x+3y)6=25.95×6

⇒36x+18y=155.7-----(3)

(x+6y)3=26.70×3

⇒3x+18y=80.1-----(4)

Subtract (4) from (3).

That is, 36x+18y-(3x+18y)=155.7-80.1

⇒33x=75.6

⇒x=2.3

Substitute x=2.3 in equation (1).

That is, 6(2.3)+3y=25.95

⇒3y=12.15

⇒y=4.05

Therefore, the cost of an order of 1 croissant is $2.3 and 1 cup of coffee is $4.05.

In the figure below, one side of the right triangle is a diameter of the semicircle.
10 units
6 units
8 units
What is the approximate total area of the shaded part of the figure?

Answers

Answer:

Option (A)

Step-by-step explanation:

One side of the given triangle is a diameter of the semicircle given.

Measure of the diameter = 10 units

Total area of the semicircle = [tex]\frac{1}{2}\pi (r^{2})[/tex]

                                              = [tex]\frac{1}{2}\pi (5)^2[/tex]

                                              = 39.27 square units

Area of the right triangle = [tex]\frac{1}{2}(\text{Base})(\text{Height})[/tex]

                                         = [tex]\frac{1}{2}(6)(8)[/tex]

                                         = 24 square units

Area of the shaded region = Area of the semicircle - Area of the right triangle

                                            = 39.27 - 24

                                            = 15.27 square units

                                            ≈ 15 square units

Therefore, option (A) will be the answer.

Step-by-step explanation:

Got it right EDGE 2021

The value of 8(26) after using the distributive property will be 208.

What is a number system?

The number system is a way to represent or express numbers.

A decimal number is a very common number that we use frequently.

Since the decimal number system employs ten digits from 0 to 9, it has a base of 10.

As per the given, 8(26)

8(26) = 8(20 + 6)

By using the distributive property of multiplication,

8(26) = 8 × 20 + 8 × 6

⇒ 160 + 48

⇒ 208

Hence "The value of 8(26) after using the distributive property will be 208".

Determine whether the vectors u and v are parallel, orthogonal, or neither.

u = <10,0>, V = <0,-9>

Answers

Answer:

Orthogonal.

Step-by-step explanation:

Given:

u = <10, 0>

v = <0, -9>

In unit vector notation, the above vectors can be re-written as:

u = 10i + 0j

v = 0i - 9j

Now, note the following:

(i) two vectors, u and v, are parallel to each other if one is a scalar multiple of the other. i.e

u = kv

or

v = ku

for some nonzero value of a scalar k.

(ii) two vectors are orthogonal if their dot product gives zero. i.e

u . v = 0

Let's use the explanations above to determine whether the given vectors are parallel or orthogonal.

(a) If parallel

u = k v

10i + 0j = k (0i - 9j)   ?

When k = 1, the above equation becomes

10i + 0j  ≠  0i - 9j

When k = 2,

10i + 0j ≠ 2(0i - 9j)

10i + 0j ≠ 0i - 18j

Since we cannot find any value of k for which u = kv or v = ku, then the two vectors are not parallel to each other.

(b) If Orthogonal

u.v = (10i + 0j) . (0i - 9j)  

[multiply the i components together, and add the result to the multiplication of the j components]

u.v = (10i * 0i) + (0j * 9j)

u.v = (0) + (0)

u.v = 0

Since the dot product of the two vectors gave zero, then the two vectors are orthogonal.

MA is perpendicular to AT.

To find: angle HAT.

Now,

angle HAT + (2x + 2)° + (3x + 5)° = 90° { As MA perpendicular to AT. }

Now,

Replace angle HAT by (3x - 5)°.

(3x-5)° + (2x+2)° + (3x+5)° = 90°

Open brackets,

3x - 5° + 2x + 2° + 3x + 5° = 90°

Add like terms.

8x + 2°= 90°

8x = 90°-2°

Here's the solution:

The density of concentrated sulfuric acid is 1.8 g/[tex]cm^{3}[/tex]. This means that 1.8 grams of concentrated sulfuric acid will occupy 1 cubic centimeter of space.

If we have 3.1 kg of concentrated sulfuric acid, then we have 3100 grams of concentrated sulfuric acid.

volume = mass / density

volume = 3100 g / 1.8 g/[tex]cm^{3}[/tex]
