A 45-45-90 right triangle is formed when a square is cut in half diagonally. This forms two such right triangles, where the sides are in a specific ratio, with the length of the hypotenuse being root 2 times the length of each leg.

A 45-45-90 right triangle is formed when a square is cut in half. This is because when you draw a diagonal on a square, the angles it forms with the sides are all 45 degrees, and the angles at the vertices remain 90 degrees. Therefore, it forms two 45-45-90 right triangles.

In a 45-45-90 triangle, the sides are in a specific ratio. The length of the hypotenuse is root 2 times the length of each leg, which are equal in measure because it is an isosceles triangle. These properties are unique to 45-45-90 right triangles.

Answer:

Sₙ = 6 x (1 - 2¹⁰) / (1 - p) = 6 x 1023 = 6138

S'ₙ =2.52

Step-by-step explanation:

sum of this sequence: Sₙ = A₁ x (1 - pⁿ) / (1 - p)

Sₙ: sum of n terms

A₁: initial value 6

p: common ratio 2

n: terms 10

Sₙ = 6 x (1 - 2¹⁰) / (1 - p) = 6 x 1023 = 6138

Is there any mistake in the 2nd question - about the common ratio (-1/2)?

S'ₙ =1 + (-1/2) + 1 x (1 - (1/2)¹⁸)) / (1 - (1/2)) = 1/2 + 2 x  (1 - (1/2)¹⁸)

S'ₙ = 1/2 + 2 x (1 - 1/262144) = 1/2 + 262143/130072= 0.5 +2.02 = 2.52

Answer:

[tex]\frac{8}{5}[/tex]

Step-by-step explanation:

Given that [tex]g(x) = \frac{x + 1}{x - 2}[/tex] and h(x) = 4 - x

Now, if y = f(x) and y = g(x) then the composite function (f∘g)(x) is given by f[g(x)].

Hence, (g∘h)(x) = [tex]g[h(x)] = \frac{(4 - x) + 1}{(4 - x) - 2} = \frac{5 - x}{2 - x}[/tex] .......... (1)

Now, from equation (1) we get,

(g∘h)(x) = [tex] \frac{5 - x}{2 - x}[/tex]

⇒ (g∘h)(- 3) = [tex]\frac{5 - ( - 3)}{2 - ( - 3)} = \frac{8}{5}[/tex] (Answer)

Answer:

The answer is 8/5

Step-by-step explanation:

To calculate the total hours you will be paid for this week, subtract the total lunch break time from the total working hours. Therefore, the total hours you will be paid for this week is 19 hours and 45 minutes.

To calculate the number of hours you will be paid for this week, you need to subtract the total lunch break time from the total working hours.

On Monday, you worked from 8 AM to PM, which is 10 hours.

On Tuesday, you worked from 9 AM to 3 PM, which is 6 hours.

On Thursday, you worked from 8:30 AM to 2:15 PM, which is 5 hours and 45 minutes.

Overall, your total working hours for the week are 10 + 6 + 5 hours and 45 minutes.

Each day you have a 30-minute unpaid lunch break, so for the entire week you would have 4 lunch breaks x 30 minutes = 2 hours taken for lunch breaks.

Therefore, the total hours you will be paid for this week are 10 + 6 + 5 hours and 45 minutes - 2 hours = 19 hours and 45 minutes.

A. Mr. Babe made a commission of $14.85

B. He makes $15.75 per hour after the raise.

Step-by-step explanation:

A. While he worked there, Mr. Babe earned 3% on how much he sells. If he sold $495 couch, how much commission did he make?

Worth of sold couch = $495

Commission = 3%

Amount of commission = 3% of total worth sold

Amount of commission = [tex]\frac{3}{100}*495[/tex]

Amount of commission = [tex]\frac{1485}{100}=\$14.85[/tex]

Mr. Babe made a commission of $14.85

B. On top of his commission, Mr. Babe made $15 per hour. He eventually got a raise with an increase of 5% per hour. After the raise, how much did he make per hour?

Amount earned per hour = $15

Increase = 5%

As the increment is on per hour amount, therefore,

Amount of increase = 5% of per hour amount

Amount of increase = [tex]\frac{5}{100}*15=\frac{75}{100} = \$0.75[/tex]

New amount per hour = Per hour amount + amount of increase

New amount per hour = 15+0.75 = $15.75

He makes $15.75 per hour after the raise.

Question:

Katy makes 48 cookies an hour. If she has 24 already, how long would it take her to make 120?

Answer:

It takes 2.5 hours for Katy to make  120 cookies

Step-by-step explanation:

Given:

Time taken to make 48  cookies = 1 hour

To Find:

Time taken to make 120 cookies = ?

Solution:

Time taken to make 48 cookies  = i hour

So now time taken to make 1 cookie  = [tex]\frac{1}{48} hour[/tex]

So time taken to make 120 cookies

= Number of cookies X time taken to make one cookie

=>[tex]120 \times  \frac{1}{48}[/tex]

=>[tex] \frac{120}{48}[/tex]

=> 2.5 hours

The equation is [tex]b=\frac{2A}{h}[/tex]

Step-by-step explanation:

Let us revise how to make a variable subject of an equation

∵ A = [tex]\frac{1}{2}[/tex] × b × h

∵ b is the subject

∴ Multiply the two sides by 2

∴ 2A = b × h

- Divide both sides by h

∴ [tex]\frac{2A}{h}= b[/tex]

- Switch the two sides

∴ [tex]b=\frac{2A}{h}[/tex]

The equation is [tex]b=\frac{2A}{h}[/tex]

Answer:

156.63 Square feet

Step-by-step explanation:

Final answer:

The area of a bedroom that is 13.62 feet by 11.5 feet is 156.63 square feet, found by multiplying the length by the width.

Explanation:

The most accurate measure of the area of a bedroom that measures 13.62 feet long and 11.5 feet wide is calculated by multiplying the length by the width. The formula for the area of a rectangle is:

Area = length × width

Thus, the area is:

Area = 13.62 feet × 11.5 feet = 156.63 square feet

This calculation ensures that you have the most accurate measure of the square footage necessary, for example, if you are planning to replace the carpet or perform other renovations that require an accurate measure of the room's floor space.

A. f(x)=x^2+x+0.25

Step-by-step explanation:

If x represents Lindsey's distance at 2:00 PM, then 2x represents Kara's distance at 2:00 PM because she walked twice as far as Lindsey. Then adding on the values we got for 2:30 PM, we get that Kara walked a distance of 2x+1 and Lindsey walked a distance of x+0.5 at the time of 2:30 PM. Now, we know that they have formed a right triangle because we are given the directions they walked in; east and north. This allows us to use a formula for the area of a right triangle: 1/2(L x W). Plugging in our values, we get...

1/2(2x+1)(x+0.5)

which simplifies to...

1/2(2x^2+2x+0.5)

which further simplifies to...

x^2+x+0.25

which is our answer.

A. f(x) = x^2 + x + 0.25

Step-by-step explanation:

Let us study the meaning independent probability  

∵ P(A) = [tex]\frac{3}{14}[/tex]

∵ P(B) = [tex]\frac{1}{5}[/tex]

∴ P(A) . P(B) = [tex]\frac{3}{14}[/tex] × [tex]\frac{1}{5}[/tex]

∴ P(A) . P(B) = [tex]\frac{3(1)}{14(5)}[/tex]

∵ P(A and B) = [tex]\frac{3}{65}[/tex]

∵ P(A) . P(B) = [tex]\frac{3}{70}[/tex]

- The two answers are not equal

∴ P (A and B) ≠ P(A) · P(B)

Events A and B are not independent.

The events A and B are independent given that P(A) = 3/14, P(B) = 1/5, and P(A AND B) = 3/65. To determine if two events are independent, the product of their individual probabilities, P(A) and P(B), should equal the probability of both events occurring together, P(A and B).

Let's calculate this:

P(A) × P(B) = (3/14) × (1/5) = 3/70

Since P(A AND B) = 3/65, we compare it to the calculated product of P(A)P(B).

P(A AND B) is not equal to P(A)P(B). Therefore, events A and B are not independent because their joint probability is not the product of their individual probabilities.

If (√4) / 9, Then,

(√4) / 9

The completed factor of given expression is  [tex]2(x-2)(x+2)(x^2+4)[/tex]

Step-by-step explanation:

Given expression is [tex]2x^4-32[/tex]

To find the completed factor for the given expression:

[tex]2x^4-32[/tex]:

Taking the common number "2" outside  to the above expression we get

[tex]2x^4-32=2(x^4-16)[/tex]

Now rewritting the above  expression as below

[tex]=2(x^4-2^4)[/tex]  (since 16 can be written as the number 2 to the power of 4)

[tex]=2((x^2)^2-(2^2)^2)[/tex]

The above expression is of the form [tex]a^2-b^2=(a+b)(a-b)[/tex]

Here [tex]a=x^2[/tex] and  [tex]b=2^2[/tex]

Therefore it becomes

[tex]=2(x^2+2^2)(x^2-2^2)[/tex]

[tex]=2(x^2+4)(x^2-2^2)[/tex]  

The above expression is of the form [tex]a^2-b^2=(a+b)(a-b)[/tex]

Here [tex]a=x[/tex] and  [tex]b=2[/tex]

Therefore it becomes

[tex]=2(x^2+4)(x+2)(x-2)[/tex]  

[tex]=2(x+2)(x-2)(x^2+4)[/tex]  

Therefore [tex]=2(x+2)(x-2)(x^2+4)[/tex]  

[tex]2x^4-32=2(x-2)(x+2)(x^2+4)[/tex]

Step-by-step explanation:

we have

[tex]25x^{2}+4y^{2}-50x-75=0[/tex]

Convert to standard form

Group terms that contain the same variable, and move the constant to the opposite side of the equation

[tex](25x^{2}-50x)+4y^{2}=75[/tex]

Factor the leading coefficient of each expression

[tex]25(x^{2}-2x)+4y^{2}=75[/tex]

Complete the square twice. Remember to balance the equation by adding the same constants to each side.

[tex]25(x^{2}-2x+1)+4y^{2}=75+25[/tex]

[tex]25(x^{2}-2x+1)+4y^{2}=100[/tex]

Rewrite as perfect squares

[tex]25(x-1)^{2}+4y^{2}=100[/tex]

Divide both sides by the constant term to place the equation in standard form

[tex]\frac{25(x-1)^{2}}{100}+\frac{4y^{2}}{100}=\frac{100}{100}[/tex]

Simplify

[tex]\frac{(x-1)^{2}}{4}+\frac{y^{2}}{25}=1[/tex]
