Answer 1

Answer:

≈ 41.2°

Step-by-step explanation:

Given ΔABD with:

AC⊥BDBC = 6 cmBD = 22 cmArea(ABC) = 42 cm²Find ∠D = x

Consider ΔABC

Area = 1/2BC*AC42 = 1/2*6*ACAC = 42/3 = 14

Consider ΔACD

CD = BD - BC = 22 - 6 = 16 cmAC = 14 cmtan x = AC/CDtan x = 14/16 = 0.875x = arctan 0.875x ≈ 41.2°

if you only have 14 packs of Fire Works and my 3 friends and I sent them off how many packs does each of us get if we share them equally ​

Answers

Answer:

4.66

Step-by-step explanation:

14 / 3 = x

4.66 = x

Answer:

So a whole number answer would be 3 per person with a remainder of 2.

or

It would be a mixed number and be 3 1/2 per person.

Step-by-step explanation:

Well you and your 3 friends are 4 people total.

4 is not a multiple of 14 so if you want to share equally youll have some leftover cause im assuming the answer must be a whole number and not a decimal.

But the most you and your friends can share equally is 3 per person. Since 4 people with 3 packs each (4 x 3) is 12 packs total with 2 packs leftover.

If you want to split these packs among the 4 of you, you can do 4/2 to get 1/2 a pack for each of you guys to share.

So a whole number answer would be 3 per person with a remainder of 2.

or

It would be a mixed number and be 3 1/2 per person.

Hope this helps!

Si un rectángulo con perímetro de 74 pulgadas tiene un largo de 5 pies más que el ancho,
¿cuáles son las dimensiones?

Answers

Perímetro del rectángulo = 74 pulgadas

Deje que el ancho del rectángulo sea 'x'.

Entonces, la longitud de este rectángulo = x + 5

We know that :

[tex]\color{hotpink}\tt \: Perímetro \: del \: rectángulo =\color{plum} 2 × (l + b) [/tex]

Lo que significa :

[tex] =\tt 2(x + x + 5) = 74[/tex]

[tex] =\tt 2(2x + 5) = 74[/tex]

[tex] =\tt 4x +10 = 74 [/tex]

[tex] =\tt 4x = 74 - 10[/tex]

[tex] =\tt 4x = 64[/tex]

[tex] =\tt x = \frac{64}{4} [/tex]

[tex]\color{plum} =\tt x = 16[/tex]

Por lo tanto, el ancho de este rectángulo = 16 pulgadas

Entonces, la longitud de este rectángulo :

[tex] =\tt x + 5[/tex]

[tex] = \tt16 + 5[/tex]

[tex]\color{plum} =\tt 21 \: pulgadas[/tex]

La longitud de este rectángulo = 21 pulgadas

Por lo tanto :

● Longitud del rectángulo = 21 pulgadas

● Ancho del rectángulo = 16 pulgadas

The constants a, b, and c are positive. Solve the inequality for x. ax - b < c

Answers

Answer:

The solution of the given inequality    [tex]x < \frac{c+ b}{a}[/tex]

Step-by-step explanation:

Explanation:-

Given that the constants a, b, and c are positive

Given inequality     a x - b < c

Adding 'b' on both sides, we get

                             a x - b + b < c

                       ⇒  a x < c + b

Dividing 'a' on both sides, we get

                            [tex]x < \frac{c+ b}{a}[/tex]

Lincoln purchased a new car in 2010 for $22,800. The value of the car was $14,100 in the year 2012, then what would be the predicted value of the car in the year 2014, to the nearest dollar?

Answers

Answer:

872

Step-by-step explanation:

The predicted value of $16,348 for the car in 2014.

What is the depreciation rate?

The depreciation rate is the percentage rate at which an asset is depreciated over its projected useful life.

Given,

The car was purchased for $22,800 in 2010.

The value of the car was $14,100 in 2012.

The time elapsed between 2010 and 2012 is 2 years, so we can calculate the annual depreciation rate as follows:

depreciation rate = (purchase price - value after 2 years) / (purchase price x 2 years)

= (22,800 - 14,100) / (22,800 * 2)

= 0.0798 or 7.98%

This means that the car depreciates by approximately 7.98% of its value per year. To predict the value of the car in 2014, we can use this rate to calculate the value after 4 years (since 2010):

value after 4 years = purchase price x (1 - depreciation rate)⁴

= 22,800 x (1 - 0.0798)⁴

≈ 16,347.97

Rounding this to the nearest dollar gives us a predicted value of $16,348 for the car in 2014.

Write a recursive formula for the sequence 180,160, 140, 120, 100...

Answers

Answer:

g(n) = 180 - 20(n-1)

Step-by-step explanation:

Since your has its g(1) value as 180, we put 180 in front. Then, we subtract 20 multiplied by n-1, n being the sequence number. For example, if the recursive function has recursed 3 times, we do 3-1, which is 2. We multiply 2 with 20, which is 40. Finally, we subtract 40 from 180, which is 140. This equation is equivalent to g(3) = 180 - 20(3-1). When the sequence has g(3), we clearly see the answer is 140. When we look at the sequence, the third number is 140, proving this equation correct.

If you deposit 4500 in an account paying 3.2% interest continually home much will the account balance be after 1.5 year

Answers

Answer:

We conclude that the total amount accrued, principal plus interest,  from compound interest on an original principal of  $4,500.00 at a rate of 3.2% per year  compounded continuously  over 1.5 years is $4,721.27.

Step-by-step explanation:

Given

Principle P = 4500 (Let say in $)Interest rate r = 3.2% = 0.032Time period t = 1.5 years

To determine

Accrue Amount A = ?

Using the formula

[tex]A\:=\:Pe^{rt}[/tex]

substitute r = 0.032, P = 4500, and t = 1.5

[tex]A\:=\:4,500.00\left(2.71828\right)^{\left(0.032\right)\left(1.5\right)}[/tex]

A = $ 4721.27

Therefore, we conclude that the total amount accrued, principal plus interest,  from compound interest on an original principal of  $4,500.00 at a rate of 3.2% per year  compounded continuously  over 1.5 years is $4,721.27.
