Number of year to get $10,000 as interest = 7.5 year (Approx)

Step-by-step explanation:

Given:

Initial investment = $20,000

Interest on investment = $10,000

Rate of interest = 5.6% = 0.056

Find:

Number of year to get $10,000 as interest:

Computation:

[tex]Interest\ on\ investment = Initial\ investment[(1+r)^n-1]\\\\10,000 = 20,000[(1+0.056)-1]\\\\0.5=(1.056)^n-1\\\\1.5 =(1.056)^n\\\\n=7.44[/tex]

Number of year to get $10,000 as interest = 7.44

Number of year to get $10,000 as interest = 7.5 year (Approx)

Answer:

$1.09

Step-by-step explanation:

Answer:

AB ≈ 7.83

Step-by-step explanation:

Using the sine ratio in the right triangle

sin50° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{BC}{AB }[/tex] = [tex]\frac{6}{AB}[/tex]

Multiply both sides by AB

AB × sin50° = 6 ( divide both sides by sin50° )

AB = [tex]\frac{6}{sin50}[/tex] ≈ 7.83 ( to the nearest hundredth )

Answer:

$13.35

Step-by-step explanation:

To find the amount of discount, multiply the discount rate by the usual price of the small TV.

discount rate * regular price

The discount rate is 15% and the regular price of the small TV is $89.00

15%*$89.00

15%*89

Convert 15% to a decimal by dividing 15 by 100, or moving the decimal place two spots to the left.

15/100=0.15

15.0-->1.5-->0.15

0.15*89

Multiply

13.35

The discount amount is $13.35

So the amount of discount is $13.35

The value of the expression using BODMAS rule is 9.

To simplify the arithmetic expression involving more operators, we need to  use BODMAS rule. The full form of BODMAS is Brackets (Parts of a calculation inside the bracket always come first), Precedence of brackets are : [{(bar)}], Orders (powers and square roots), Division, Multiplication, Addition, Subtraction.

For the given situation,

The values are c = -4, d = 10

The expression is 1/4(c^3+d^2)

Substitute the above values,

⇒ [tex]\frac{1}{4}(c^{3}+d^{2} )[/tex]

⇒ [tex]\frac{1}{4} (-4^{3} +10^{2} )[/tex]

⇒ [tex]\frac{1}{4}(-64+100)[/tex]

⇒ [tex]\frac{1}{4}(36)[/tex]

⇒ [tex]9[/tex]

Hence we can conclude that the value of the expression using BODMAS rule is 9.

AB:

a² + b² = c²

'a' and 'b' are legs, while 'c' is the hypotenuse

3.6² + 5.2² = 12.96 + 27.04

c² = 40

c = √40

c ≈ 6.3

m∠A:

sine, cosine, tangent

soh - [tex]\frac{opposite}{hypotenuse}[/tex]

cah - [tex]\frac{adjacent}{hypotenuse}[/tex]

∠a:

[tex]\frac{5.2}{6.3}[/tex] = 0.825396...

x = sin^-1(0.825396)

x = 55.6 ≈ 56º

Answer:

x=-2 and x=-8

Step-by-step explanation:

(x+5)=3

Subtract 5 from both sides, to isolate x

x=-2

-(x+5)=3

Distribute the -

-x-5=3

Add 5 to both sides to isolate x

-x=8

Multiply both sides by -

x=-8

Answer:

12.4 units

Step-by-step explanation:

The diameter of circle J is represented by KN. Half of KN is KJ and JN which means these represent the radius. Since JN equals 12.4 and JN is the the radius, then the radius of circle J is 12.4 units which is answer choice D.

The radius of the given circle is 6.2 unit. So option B is correct.

A line segment from a circle's or sphere's center to its perimeter or boundary is known as the radius in geometry. It is a crucial component of spheres and circles and is frequently abbreviated as "r". When discussing multiple radiuses at once, the plural form of radius is "radii". The diameter of a circle or sphere is the longest line segment connecting all points on the opposite side of the centre, and the radius is equal to half of the diameter in length. It can be written as d/2, where d is the circle's or sphere's diameter. Look at the illustration of a circle below that depicts the connection between radius and diameter.

Given that,

A circle,

which contains diameter KN of length 12.4 unit

and chord 10.8 unit.

The radius = ?

It is known that, the length of the radius is half of the diameter of the circle,

R = D/2

  = 12.4/2

  =  6.2

Therefore, the length of the radius is 6.2 unit.

Answer:

=18.38cm

Step-by-step explanation:

The longest line segment in a right rectangular prism is the diagonal that connects two opposite vertices. On the first diagram attached, the green line segment connecting A and G is one such diagonals. The goal is to find the length of segment .

Look at the attached picture. The longest segment we can draw is AG (or any of its equivalent: BH, CE, DF). Let's focus on AG for example.

We can think of AG as the hypotenuse of triangle ACG. So, we need AC first. AC is itself the hypotenuse of triangle ABC,

so we have,

[tex]AC^2 = AB^2+BC^2=8^2+7^2=113[/tex]

Now we can resume where we stopped with triangle AGC, and we have

[tex]AG=\sqrt{AC^2+CG^2}=\sqrt{113+225}=\sqrt{338}[/tex]

=18.38cm

Answer:

(0, 3)

Step-by-step explanation:

Let's first eliminate x.  To do this, multiply all three terms of the first equation by 5:  

-5x + 20y = 60

5x -    2y  = -6

----------------------

         18y = 54, so that y = 3.

Substituting 3 for y in the first equation yields:

-x + 4(3) = 12, or -x = 0.  Thus, x = 0, and the solution is

(0, 3)

Answer:

There are 7,200

Step-by-step explanation:

Hope this helps!

There are 8400 4-digit numbers that are neither multiples of 2 nor multiples of 5.

The sequence is a pattern of placing the values in a specified manner.

To count the number of 4-digit numbers that are not multiples of 2 or 5, we can use the principle of inclusion-exclusion.

First, let's count the total number of 4-digit numbers. We know that the smallest 4-digit number is 1000 and the largest 4-digit number is 9999. Therefore, the total number of 4-digit numbers is:

9999 - 1000 + 1 = 9000

Next, let's count the number of 4-digit numbers that are multiples of 2. We know that a number is a multiple of 2 if its last digit is even, so half of the 10 possible digits can be the last digit of a multiple of 2. Therefore, there are:

5 × 10 × 10 = 500

4-digit multiples of 2.

Similarly, let's count the number of 4-digit numbers that are multiples of 5. We know that a number is a multiple of 5 if its last digit is 0 or 5. Therefore, there are:

2 × 10 × 10 = 200

4-digit multiples of 5.

Now, we need to subtract the number of 4-digit numbers that are multiples of both 2 and 5 (i.e., multiples of 10) since they were counted twice in the above calculations. There are:

1 × 10 × 10 = 100

4-digit multiples of 10.

Using the principle of inclusion-exclusion, the number of 4-digit numbers that are neither multiples of 2 nor multiples of 5 is:

9000 - 500 - 200 + 100 = 8400

Therefore, there are 8400 4-digit numbers that are neither multiples of 2 nor multiples of 5.

Answer:

(2, 3) x=2, y=3

Step-by-step explanation:

There are two ways to solve this: substitution & elimination:

Using substitution for this equation:

[tex]\left \{ {{3x+y=9} \atop {5x+4y=22}} \right.[/tex]

3x + y =9

y = 9-3x

Substitute for y:

5x + 4(9 - 3x) = 22

5x + 36 - 12x = 22

-7x = -14

x = 2

Solve for y:

3(2) + y = 9

6 + y = 9

y = 3
