Mmh same for me! QwQ I see your a Gacha person too! Anyways, let's get on with the question. Well I'm not so sure about this! :< So The Divisor is a two-digit number (For example, 10 since it has 2 numbers/2 digits). Next we have to write a rule for how many digits in the dividend you will need to look at to complete the first step in dividing. Dividing two fractions is the same as multiplying the first fraction by the reciprocal of the second fraction. The first step to dividing fractions is to find the reciprocal (reverse the numerator and denominator) of the second fraction. Next, multiply the two numerators. Then, multiply the two denominators. This is a fraction way (Read this carefully) I PUT ThiS PART IN CAPS SO YOU CAN SEE THE WARNING XD. Alright so, the warning is this is for fractions.

We have to find it for a two-digit number So, Divide the first number of the dividend (or the two first numbers if the previous step took another digit) by the first digit of the divisor. Write the result of this division in the space of the quotient. Multiply the digit of the quotient by the divisor, write the result beneath the dividend and subtract it. There! I hope this helps you this took a long time.

What should be added to 4x²-3x²+1 to make it a perfect square​
Vlad1618 [11]

im \: guessing \: its \: 4x {}^{2}  - 3x + 1 \\ (correct \: me \: if \: im \: wrong)

(a - b) {}^{2}  = a {}^{2}   - 2ab +  {b}^{2}

4x {}^{2}  = a {}^{2}  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \: b {}^{2}  = 1 \\ a = 2x \:  \:  \:  \:  \: \:  \:  \:  \:  \:  \:  \:  \:  \: b = 1

(2x - 1) {}^{2}  = 4x {}^{2}   -4x + 1

we \: need \: to \: add \: a \: - x \\ \: to \: the \: original \: equation

<h2>Note that this problem can be approached in many ways. For instance, we can add to the b² term instead of changing the middle term...</h2>

A rectangular field measures 227 by 56 yards. How far is it to walk from one corner of the field to the opposite corner? How far
GaryK [48]

Answer:

233.8 Yards

Step-by-step explanation:

Given that,

Length of a rectangular field, l = 227 yards

Breadth of a rectangular field, l = 56 yards

Let x is the distance from one corner of the field to the opposite corner. It can be calculated using Pythagoras theorem,

x=\sqrt{l^2+b^2} \\\\x=\sqrt{(227)^2+(56)^2} \\\\x=233.8\ \text{Yards}

So, the distance from one corner of the field to the opposite corner is 233.8 Yards.

The image is not very much enlarged, and is slanted, so answers might be just approximate.
(a) median is 39 or 40, your choice.
(b) 3rd quartile of y looks 47 or 48
(c) variable y has more disperson, since both the extremes and the quartiles are spread out longer that those of variable x.
(d) since both halfs of the blue box (of x) and both lines outside of the box are basically equal, variable x's distribution is very much symmetric.
Sorry, cannot read question part (e) completely.

A town has a population of 20000 and grows at 4% every year. How long will it be until the population will reach 39400?
olga55 [171]

Answer:

The population will be 39400 in approximately 17 years

Step-by-step explanation:

The increase in population after t years is given by the formula

P_t = P_0(1+r)^t

Here

P_0 is the initial population

r is the growth rate and t is time in years

So far we know,

P_0 = 20000

r = 4%

P_t = 39400

Putting the values in the formula

39400 = 20000(1+0.04)^t\\39400 =20000(1.04)^t\\\frac{39400}{20000} = (1.04)^t\\1.97 = (1.04)^t

Taking natural log on both sides

ln |(1.04)^t| = ln |1.97|\\t\ ln\ |1.04| = ln\ |1.97|\\t = \frac{ln\ 1.97}{ln\ 1.04}\\t = 17.287\\t \approx 17

Hence,

The population will be 39400 in approximately 17 years
