How to Do Long Division with Decimals

If the number you're dividing by has a decimal, move the decimal point all the way to the right counting the number of places you've moved it to. Then move the decimal point in the number you're dividing the same number of places to the right.

Insert a decimal point in the quotient (answer) space, exactly above the decimal point in the number under the division bar.

Divide until the remainder is zero, or until you have enough decimal places in your answer. You can also stop if the remainder repeats because this indicates that your answer is a repeating decimal.

It will take 27 minutes for all the kids to have gone home

The given parameters are:

9 kids every 3 minutes

This can be represented as

9 kids = 3 minutes

Let the time spent by 81 kids be x

So, we have the following equation

81 kids = x

Rewrite the parameters as

9 kids = 3 minutes

81 kids = x

Cross multiply in the above equation

So, we have:

9 * x = 3* 81

Divide both sides by 9

x = 3 * 9

Evaluate

x = 27

Hence, it will take 27 minutes for all the kids to have gone home

Zoe travels 380 yards on foot from her home to the bus station. The distance between Zoe's home and the bus stop fluctuates from 250 yards to 410 yards when her distance from her home rises from 50 yards to 210 yards.

Distance is the measurement of the separation between two points. Since distance is a scalar quantity, it solely cares about its measurement or amount. Distance is measured and often stated in terms of meters in SI units (m).

Given,

zoe walks from her house to a bus stop that is 460 yards

and zoe's distance from her house increases from 50 yards to 210 yards,

So,

d1 = 460 yards - 50 yards

= 410 yards

d2 = 460 yards - 210 yards

= 250 yards

Answer:

x = 19

z = 64

Step-by-step explanation:

Angles (11x - 93)° and 116° are vertical angles, so their measures are equal.

11x - 93 = 116

11x = 209

x = 19

Angles z° and 116° are a linear pair, so they are supplementary, and their measures have a sum of 180°

z + 116 = 180

z = 64

Approxiamtely 167 men will be there in a class if the percent of men is 58.6 of the total student.

According to the given question.

Total number of students in the class is 285.

And 58.6 percent of the total students are men.

As we know that, a relative value indicating hundredth parts of any quantity is called a percent.

Therefore,

the total number of men in the class

= 58.6 percent of 285

= (58.6/100) × 285

= 0.586 × 285

= 167.01

For the given line segment, the value of variable d is 2 units and the value of YZ is 16 units.

Given that, Y is between X and Z.

We need to find the value of the variable and YZ.

A line segment is a part of a line that has two endpoints and a fixed length. It is different from a line that does not have a beginning or an end and which can be extended in both directions.

Given that, XY=11d, YZ=9d-2, XZ=5d+28

Here, the line segment XZ is sum of XY and YZ

That is, XZ=XY+YZ (∵Y is between X and Z)

⇒5d+28=11d+9d-2

⇒5d+28=20d-2 (Add like terms that is 11d+9d=20d)

⇒20d-5d=28+2

⇒15d=30

⇒d=2

So, YZ=9d-2

=9×2-2=18-2

=16

Therefore, the value of variable d is 2 units and the value of YZ is 16 units.

Question 2

Subtract function g(x) from function f(x):

[tex]\begin{aligned} \implies f(x)-g(x) & = (4x^2+2)-(4x^2+2x+1)\\& = 4x^2+2-4x^2-2x-1\\& = 4x^2-4x^2-2x+2-1\\& =-2x+1\end{aligned}[/tex]

Question 3

Add function h(x) and function g(x) together:

[tex]\begin{aligned} \implies h(x)+g(x) & = (-3x+4)+(4x^2+2x+1)\\& = -3x+4+4x^2+2x+1\\& = 4x^2-3x+2x+4+1\\& = 4x^2-x+5\end{aligned}[/tex]

Question 4

Subtract function f(x) from function h(x):

Question 5

Add function g(x) when x = 2 to function f(x):

So we get an equation,

x + (0.6 x) = 6720

We solve above equation for x.

1.6 x = 6720

x = 6720 / 1.6
