Answer:

8(20 + 6)

8(20) +8(6)

208

Step-by-step explanation:

Got it right EDGE 2021

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

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".

The value of the gauge car after 4 years will be $18195.25.

Compound interest is applicable when there will be a change in principle amount after the given time period.

For example, if you give anyone $500 at the rate of 10% annually then $500 is your principle amount. After 1 year the interest will be $50 and hence principle amount will become $550 now for the next year the interest will be $550, not $500.

Given,

Principle amount (P)  = $29000

Rate of decrement (R) = 11%

Time period(T) = 4 years

Percentage decrement over T time period is given by

Final amount = P[tex][1 - R/100]^{T}[/tex]

Final amount = 29000[tex][1 - 11/100]^{4}[/tex]

Final amount = 29000(0.89)⁴

Final amount = $18195.25.

Hence, The value of the gauge car after 4 years will be $18195.25.

The value of the car after 4 years is $18195.24989.

Given,

Gage bought a new car for $29000 to use while he is away at college.

The car decreases in value by 11% annually.

We need to find what would the cars value after 4 years.

we have,

Cost of the car = $29000

The car decreases annually by = 11%

1st-year decrease.

$29000 x 11/100 = $3190

The cost of the car after 1st year = $29000 - $3190 = $25810

2nd-year decrease.

$25810 x 11/100 = $2839.1
The cost of the car after 2nd year = $25810 -  $2839.1 = $22970.9

3rd-year decrease.

$22970.9 x 11/100 = $2526.799

The cost of the car after 3rd year = $22970.9 - $2526.799 = $20444.101

4th-year decrease.

$20444.101 x 11/100 = $2248.85111

The cost of the car after 4th year = $20444.101 - $2248.85111 = $18195.24

Thus the value of the car after 4 years is $18195.24989.

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%

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

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

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

Step-by-step explanation:

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

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.

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.

Hey, there!!

Let's simply work with it,

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°

[tex]x = \frac{88°}{8} [/tex]

x= 11°.

Now, finding the value of angle HAT.

(3x-5)° = 3×11°-5°

Therefore, angle HAT is 28°.
