Answer: 130875 automobiles

Step-by-step explanation:

To estimate the total number of automobiles owned in 2005, let's first find the number of years

2005 - 1990 = 15 years

Given that the Commercially owned automobiles in the United States can be modeled by the function

A(x) = 1.4x – 130.6x² + 1831.3x + 128,141, where x is the number of years after 1990

and A(x) is the number of automobiles in thousands.

Substitute 15 for x in the function

A(x) = 1.4(15) – 130.6(15)² + 1831.3(15) + 128,141

A(x) = 21 - 29385 + 27469.5 + 128141

A(x) = 126246.5 automobiles

The number of privately-owned automobiles in the United States can be modeled by the function

P(x) = -x + 24.9x² – 177.9x + 1709.5, where x is the number of years after 1990 

Substitute 15 for x in the function

P(x) = -(15) + 24.9(15)² – 177.9(15) + 1709.5

P(x) = -15 + 5602.5 - 2668.5 + 1709.5

P(x) = 4628.5 automobiles

The total automobile = A(x) + P(x)

Substitutes for A(x) and P(x)

The total automobile = 126246.5 + 4628.5

= 130875

Therefore, the total number of automobiles owned in 2005 is 130875 automobiles

Answer:

x = 29/20 or x = 1.45

Step-by-step explanation:

6/x + 5/(4x) = 5

Multiply all terms by x and cancel.

6 + 5/4 = 5x

Combine terms on the left side of the equation.

29/4 = 5x

Divide both sides by 5.

29/4/5 = (5x)/5

29/20 = x

Answer:

Step-by-step explanation:

[tex] \frac{6}{x} + \frac{5}{4x} = 5[/tex]

Multiply through by the LCM

The LCM of x and 4x is 4x

So we have

[tex] {4x} \times \frac{6}{x} + {4x} \times \frac{5}{4x} = 5 \times {4x} \\ \\ 24 + 5 = 20x \\ \\ 20x = 29 \\ \\ x = \frac{29}{20} \: \: \: or \: \: \: 1 \frac{9}{20} [/tex]

Answer:

The nth term of the sequence is

Step-by-step explanation:

The sequence above is an arithmetic sequence

For an nth term in an arithmetic sequence

A(n) = a + ( n - 1)d

where a is the first term

n is the number of terms

d is the common difference

From the question

a = 7

d = 9 - 7 = 2 or 11 - 9 = 2

So the nth term for the sequence is

A(n) = 7 + ( n - 1)2

= 7 + 2n - 2

Answer:

3.04 m²

Step-by-step explanation:

Surface Area =0.8x0.4 = 0.32 (two of these - one on each end)

1x0.4=0.4 (two of these - top and bottom) (Strange to cover bottom with screen, but have to follow the directions.)

1x0.8=0.8 (two of these - front and back)

TOTAL = 0.32+0.32+0.4+0.4+0.8+0.8=3.04

Total amount of screen that Alice will need for her habitat is 3.04 meter square

The surface area of a solid object is a measure of the total area that the surface of the object occupies.

Given,

Dimensions of the Caterpillar habitat is,

Width w=1 meter

Length l= 0.4 meter

Height h= 0.8 meter

Surface area = 2lw+2lh+2hw

=2×0.4×1+2×0.4×0.8+2×0.8×1

=0.8+0.64+1.6

=3.04 meter square

Hence, Total amount of screen that Alice will need for her habitat is 3.04 meter square

Work Shown:

T = tens digit of the original number

U = units digit of the original number

U+T = 10 since the digits add to 10. Solve for U to get U = 10-T

10T+U = original number

10U+T = new number where digits are reversed

-----------

new number = (old number) + 36

10U+T = (10T+U)+36

10U+T = 10T+U+36

10(10-T)+T = 10T+10-T+36 ... plug in U = 10-T

100-10T+T = 10T+10-T+36

-9T+100 = 9T+46

100-46 = 9T+9T

54 = 18T

18T = 54

T = 54/18

T = 3 is the tens digit of the original number

U = 10-T

U = 10-3

U = 7 is the units digit of the original number

10T+U = 10*3+7 = 30+7 = 37 is the original number

Answer:

1. Both forward and backward

2. Only forward

Step-by-step explanation:

    The reason Statement 1 can be both forward and reverse is because is Bo and Mel are related then it will word forward and backward.

The reason Statement 2 can be only forward is because is the sprinklers are on then the grass is wet will work since it is saying ONLY the sprinklers are on. If it is reverse and the grass is wet if the sprinklers are ONLY on than that is false since if it rains than the grass can also be wet. So there are multiple ways that the grass can be wet hence the answers.

Answer:

Using everyday knowledge, indicate whether the if-then statements are correct forward-only or both forward and reverse. Statement 1: If Bo is Mel’s sibling, then Mel is Bo’s sibling. / Statement 2: If the sprinklers are on, then the grass is wet.

The depth of the submarine after 4 stages of rising to the surface will be 100 meters.

Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

It is given that a submarine is only allowed to change its depth by rising toward the surface in 60-meter stages. The submarine starts off at 340 meters below sea level.

The depth of the submarine after 4 stages will be calculated as below:-

depth = 4 x 60 = 240

depth from the surface = 340 - 240 100 meters

Therefore, the depth of the submarine after 4 stages of rising to the surface will be 100 meters.

The leading 0 is important with true bearings. Any true bearing must be three digits.

======================================================

Explanation:

It's not stated, but I'm assuming that Binji and Congo form a flat horizontal line.

B = Binji's location

M = Milton's location

C = Congo's location

The given angles are M = 76 and C = 38. The missing angle is

B = 180-M-C

B = 180-76-38

B = 66

Subtract this from 90 to get 90-66 = 24

The true bearing of Milton from Binji is 024 degrees

In other words, if you are at Binji's location, face directly north, and turn 24 degrees clockwise (turn to the right), then you'll be facing Milton's location.

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

Extra info:

In terms of compass notation, the true bearing of 024 degrees converts to N 24 E. This is the same as E 66 N, though convention usually has north used more often (since it's a common reference point with compasses).

N 24 E = start facing north, turn 24 degrees to the east

E 66 N = start facing east, turn 66 degrees to the north

[tex](x,y)\rightarrow(x-3,y+5)[/tex]

Step-by-step explanation:

"5 units up" would be "5 added to the current y-value".

"3 units to the left" would be "3 subtracted from the current x-value".

So, the translation rule is:

[tex](x,y)\rightarrow(x-3,y+5)[/tex]

Therefore, Option C should be the correct answer.

Brainilest Appreciated.

The Rule describes the translation is :  (x, y) - (x - 3, y + 5)

We have a rectangle on a coordinate plane is translated 5 units up and 3 units to the left.

We have to determine which of the given rules describes the translation.

The new coordinates of this point P will be - P'( - 1, 13).

According to the question, we have -

Upward translation = 5 units

When the upward translation will take place then, each and every point that lies on that rectangle will have its y - coordinate shifted upwards by +5 units.

Leftward Translation = 3 units

When the leftward translation will take place then, each and every point that lies on that rectangle will have its x - coordinate shifted by  - 3  units

to the left.

Hence, rule describes the translation is : (x, y) - (x - 3, y + 5).

Answer:

$5.70

Step-by-step explanation:

First we have to find out how much she spent. SO we do 25-2.20 which is 22.80. Then we have to divide by 4 since she buys four canvases that are the same price. SO 22.80/4=$5.70

Answer: 5.70

Step-by-step explanation:

Gift card = 25

Canvases = x

Since Andrea is buying four canvases, we can say that it is 4x.

Remaining balance = 2.20

Let's set up our equation. To set it up, we can write it like this

4x+2.20= 25

Now, subtract 2.20 on each side

4x = 22.8

Now divide, and you get around 5.70

So, each canvas was $5.70

Answer:

Mr. Weaver invested $ 2,000 in the 4% simple interest account and $ 4,000 in the 7% simple interest account.

Step-by-step explanation:

1. Let's review the information given to us to answer the question correctly:

Amount of the inheritance = $ 6,000

Interest rate of the first part = 4% simple

Interest rate of the second part = 7% simple

Interest of the accounts after the first year = $ 360

2. How much did he invest in each account?

For answering the question, we will use the following equation:

x = Amount invested in the first account

6,000 - x = Amount invested in the second account

0.04x + 0.07 * (6,000 - x) = 360

0.04x + 420 - 0.07x = 360

-0.03x = 360 - 420 (Subtracting 420 at both sides)

-0.03x = -60

x = -60/-0.03

x = 2,000 ⇒ 6,000 - x = 4,000

Mr. Weaver invested $ 2,000 in the 4% simple interest account and $ 4,000 in the 7% simple interest account.
