What is -2(x + 3 ) = -2x-6

Answer:

Given -

Now, we'll calculate the work done by both the taps -

[tex] \\ \sf \: \frac{1}{4} + \frac{1}{6} \\ \\ \\ \bf \: lcm \: \: of \: \: 4 \: \: \& \: \: 6 = 12 \\ \\ \\ \implies \sf \: \frac{3 + 2}{12} \\ \\ \\ \implies \sf \frac{5}{12} \\ \\ [/tex]

Now, reciprocal it -

[tex] \\ \implies \sf \frac{12}{5} = 2 \frac{2}{5} \\ [/tex]

Therefore, time taken by both the taps will be 2 2/5 hours.

Answer:

Multiply by a power of 10

Step-by-step explanation:

By multiplying a power of ten, it will make the decimals whole numbers.

For example: 0.75*10=75

0.0075*10000

To eliminate the decimals, the first step we can perform is to multiply the decimal by a power of 10. If there are n numbers after the decimal point, then we will multiply the decimal by 10ⁿ.

In Algebra, a decimal is a type of number with a whole integer and a fractional part separated by a decimal point. The dot that appears between the entire number and the fractions part is the decimal point. 24.589, for example, is a decimal number. The whole number part is 24 and the fractional part is 589. The decimal point is ".".

If an equation contains decimals, then we have to check how many numbers are there in the fractions section. If there are 3 numbers like 24.589, to eliminate decimals we have to multiply 24.589 by 10³ to get a whole number [ Since 24.589×10³ = (24589/1000)× 1000 = 24589].

Therefore, to eliminate the decimals, the first step we can perform is to multiply the decimal by a power of 10. If there are n numbers after the decimal point, then we will multiply the decimal by 10ⁿ.

Answer:

Range A = 386ft

Range B = 427ft

B has the larger range.

Explanation:

To find the range, find the difference between the minimum and maximum depths for each submarine. Remember that your answer will be positive.

Sub A:

-146ft - (-532ft) = 386 ft

Sub B:

-194ft - (-621ft) = 427 ft

Submarine B has a larger range.

If the circle is inside the square the area of the square is 144

Step-by-step explanation:

The diameter of a circle is equal to the side length of a square.

So [tex]d = 2r[/tex]  the diameter of the circle is 2(6)=12

so one side length of the equals 12

Area of square = [tex]s^{2}[/tex]    [tex]12^{2} = 144[/tex]

Step-by-step explanation:

Answer:

The question is incomplete. The complete question is :

A plane traveling at a constant speed flew over Pittsburgh, Saint Louis, Albuquerque, and Phoenix on its way from New York to San Diego.

Complete the table as you answer the questions. Be prepared to explain your reasoning.

       segment                              time                     distance        speed

Pittsburgh to Saint Louis    1 hour                    550 miles  

Saint Louis to Albuquerque 1 hour 42 minutes  

Albuquerque to Phoenix                             330 miles  

Step-by-step explanation:

We can complete the table as :

  segment                              time                     distance        speed

Pittsburgh to Saint Louis    1 hour                   550 miles   550 miles/hour

Saint Louis to Albuquerque 1 hour 42 minutes    93.5 miles 550 miles/hour

Albuquerque to Phoenix   3/5 hour           330 miles 550 miles/hour

Since it is given in the question that the plane is flying in a constant speed from one place top another place.

So, it is maintaining the same speed to cover different distances for different time.

Thus the constant of proportionality is 550.

angle DBC = 38° ( Alternate Interior Angles )

angle ABD = 38° ( Alternate Interior Angles )

2 (angle ADC) = angle ABC

or, 2 (angle ADC) = 38° + 38°

or, 2 (angle ADC) = 76°

or, angle ADC = 76/2 = 38°

x = 38°

Step-by-step explanation:

Point A (-4,3)

Point A is in quad 2

So, . . . Point A' will be in quad 4 (+,-)

Therefore, you switch the signs.

Point A' (4,-3)

The new position of the point (-4,3) will be (4,-3) after rotation.

The process of changing the location of the image on the coordinate system will be known as the translation. An object is rotated by turning it around the center of rotation, which is a point.

Given that point A is located at coordinates (-4,3). The new coordinates of A' after a rotation of 180 degrees using (0,0) as the center of rotation.

As it is given point A is rotated about the origin at 180 degrees. Then the new coordinates of the points will be at the same magnitude but with the opposite sign.

Point A (-4,3)

Point A' will be in quadrant 4 ( +,- )

Point A' = ( 4, -3).

Therefore, the new position of the point (-4,3) will be (4,-3) after rotation.

Answer:

He does that because he is short and his hand can't reach the 20th floor button

Step-by-step explanation:

Mitch does that simply because he is short.

When he is leaving, he doesn't need to reach the 20th floor button because the button is way taller than the reach of his hands whereas when he is returning he has to reach the 20th floor button but his hand can only reach the 15th floor button. Thus, he gets to the 15th floor and walks up the remaining 5 flights.

Answer:

To the nearest thousands; 36,000 customers were surveyed.

Step-by-step explanation:

Conversion of figures to the nearest thousand often requires rounding up digits that are not up to 5 in the place of hundreds to zero and rounding up the digits that are up to 5 in the place of hundreds to one, therefore, adding it to the value of the previous thousands.

From the given  question, to round up the number of customers surveyed in the company, we have the following:

since we are given the value to be 36,219

9 is in unit position

1 is in tens

2 is in hundreds

6 is in thousands

3 is in ten thousand

since the value of 2 in hundred is not up to 5, we round it up to zero, Then our value becomes 36,000 to the nearest thousand.

Step-by-step explanation:

Given that the initial charge/fee for the first 5 minutes is $6

and also the additional rate per minutes is $0.6

we can model the total charges after the equation of a straight

that y= mx+c

now using the required notation

C= 0.6t+ 6

comparing this with the equation of a straight line

the constant term c is $6 flat rate for the first 5 minutes

the gradient 0.6 is m

the dependent variable x is t

and the cost C is y  

Answer:

i believe its c=0.60t+3

Answer:

b = 36 is the lie.

Step by step:

If we plug in b with it equaling -36 the equation will be

-39 - (-36) which you remove the minus from the -36 and change the subtraction to addition and you get

-39 + 36 = -3

In the end b = -3

So the other one must be wrong, but just incase we will plug it in.

-36 - 36 = 0

Plugging in 36 for b results in 0 which is not correct.
