9x = 5x + 12

A. x = 8
B. x = 1
C. x = 16
D. x = 3

Answers

Answer 1

Answer:

3 is the ans (any more que)

Answer 2

Answer:

D. x=3

Step-by-step explanation:

9x = 5x + 12. We have to make sure it's right.

9x3= 27.

27x3=27.

5x3= 15.

27=15+12.

15+12=27.

Do is the correct answer.

Answers

Answer:

242 ft²

Step-by-step explanation:

The shape can be decomposed to give us a trapezium and a rectangle

Area of the shape = area of the trapezium + area of the rectangle

✔️Area of the trapezium = ½(a + b)h

a = 14 ft

b = 20 ft

h = 13 - 7 = 6 ft

Area = ½(14 + 20)*6

Area of trapezium = 102 ft²

✔️Area of rectangle = L*W

L = 20 ft

W = 7 ft

Area = 20*7 = 140 ft²

✔️Area of the shape = 102 + 140 = 242 ft²

What is the surface area of the rectangular prism?



16 cm 2
48 cm 2
96 cm 2
80 cm 2

Answers

Answer:

Surface area = 80 cm²

Step-by-step explanation:

Surface Area of rectangular prism = 2(LW + LH + WH)

L = 4 cm

W = 4 cm

H = 3 cm

Plug in the values

Surface Area = 2(4*4 + 4*3 + 4*3) = 2(16 + 12 + 12)

Surface Area = 2(40) = 80 cm²

Use a linear approximation (or differentials) to estimate the given number. (Round your answer to two decimal places.) (1.999)3

Answers

Consider the function f(x) = x ³. Since 2³ = 8 is a perfect cube that is pretty close to x = 1.999, take the linear approximation to f(x) at x = 2. It is

f(x)L(x) = f (2) + f ' (2) (x - 2)

Compute the derivative:

f(x) = x ³   →   f ' (x) = 3x ²   →   f ' (2) = 12

Then

L(x) = 8 + 12 (x - 2) = 12x - 16

Now approximate 1.999³ :

f (1.999) ≈ L (1.999) = 12•1.999 - 16 = 7.988

(Compare this to the actual value, 7.98801.)

Which one of the following is a purely fixed cost?

Total Per Unit Total Per Unit
Cost A 500 0.2 1000 0.2
Cost B 2000 5 2000 2.5
Cost C 750 3.2 1000 2.4
Cost D 100 0.5 250 0.3
A. Cost A
B. Cost B
C. Cost C
D. Cost D

Answers

Answer:

The answer is "Option A and Option B"

Step-by-step explanation:

In question 1:

The fixed cost=2621.21  

The unit variable cost=35.58  

Calculating the total cost for 45 boat slips:

[tex]=2621.21+(45 \times 35.58)\\\\=2621.21+(1601.1)\\\\=4222.31 \approx 4222[/tex]

In question 2:

It is the pure fixed costs that remain consistent in total regardless of dynamic loads. An overall cost B both for 1000 and 2000 unit is unchanged, therefore the Cost B is a fixed sum.

According to the recent poll, 22 1/4% of the people polled said that they approved of the city plan to expand the library. If 1004 people was polled, about how many were in favor of the expansion?

Answers

Answer:

Some 224 people were in favor of the expansion.

Step-by-step explanation:

Given that, according to the recent poll, 22 1/4% of the people polled said that they approved of the city plan to expand the library, if 1004 people was polled, to determine how many were in favor of the expansion should be done the following calculation:

1/4 = 0.25

100 = 1004

22.25 = X

1004 x 22.25 / 100 = X

223.39 = X

Thus, some 224 people were in favor of the expansion.

Jace purchases a new motorcycle for $8000. The bike depreciates 12% every year.
Write two equations that models the price of the bike after 5 years.

Answers

Answer:

We know that the original price of the bike was $8,000.

After one year, the price of the bike decays a 12%, then the new price of the bike is:

P(1) = $8,000*( 1 - 12%/100%) = $8,000*(1 - 0.12)

After another year, the price again decays a 12%, the new price will be:

P(2) = $8,000*(1 - 0.12)*(1 - 12%/100%) = $8,000*(1 - 0.12)*(1 - 0.12) = $8,000*(1 - 0.12)^2

We already can see the pattern here, after t years, the price of the bike will be:

P(t) = $8,000*(1 - 0.12)^t

With this equation, we can find the price of the bike after 5 years, where we only need to replace t by 5

We will get:

P(5) = $8,000*(1 - 0.12)^5 = $4,221.9

The price of the bike after 5 years is  $4,221.9.

Now we want two equations to represent this, so we need another.

This is kinda trivial, because there is only one equation that represents this, so we only can rewrite our equation in another form.

We could say that the price of the bike after t years is:

P(t) = $8,000*(0.88)^t

or something like:

P(t) = $7040*(0.88)^(t - 1)

Where i multiplied the initial value by 0.88, and then reduced the exponent by one.
