How do you model whole number divided by mixed number?

2 answers:

4 0

Make the whole number a fraction by putting a 1 in the denominator of the whole number.
for the mixed number, multiple the number by the denominator of the fraction it is with, then add that number to the numerator of the fraction.
then multiply the whole number by the reciprocal of the fraction.

example: 2 divided by 5 1/3

2/1 divided by (5•3+1=16/3)
2/1 multiplied by 3/16
2•3=6
1•16=16
6/16 simplified to 3/8
so 3/8 would be your answer.

Write the equation of the line that passes through the given points<br> (0,2)) and (-9, -3)

Irina18 [472]

Step-by-step explanation:

Y= m x+ C

m (slope ) = 2 - (_3) / 0 _( - 9 )

= 5 / 9

( O, 2 ) Satisfying equation

2= 5/9 ( 0) + C

C= 2

So eq. is

y= 5/ 9 X + 2

Which of the following lists the angles from smallest to largest?

ioda

Here is your answer

The angle opposite of the larger side is greater and vice versa.

Here

smallest side= AC (8cm)< BC (9cm) <AB (10cm)

So,

angles opposite to these sides are

B <A <C

Which is the completely factored form of 4x2 28x 49? (x 7)(4x 7) 4(x 7)(x 7) (2x 7)(2x 7) 2(x 7)(x 7)

The completely factored form of 4x^2 + 28x + 49 is given by: Option C: (2x+7)(2x+7)

<h3>How to find the factors of a quadratic expression?</h3>

If the given quadratic expression is of the form ax^2 + bx + c, then its factored form is obtained by two numbers alpha( α ) and beta( β) such that:

$b = \alpha + \beta \\ ac =\alpha \times \beta$

Then writing b in terms of alpha and beta would help us getting common factors out.

Sometimes, it is not possible to find factors easily, so using the quadratic equation formula can help out without any trial and error.

For this case, the given quadratic expression is:

$4x^2 + 28x + 49$

So we've to find two numbers such that:

Their sum = b = 28

Their product = $ac = 4\times 49 = 196$

We can see that 196 is square of 14, and that 14 added twice forms 28, thus:

14 + 14 = 28

14×14 = 196

Writing b = 28 as sum of 14 twice, we get:

$4x^2 + 28x + 49 = 4x^2 + 14x + 14x +49 \\4x^2 + 28x + 49 = 2x(2x+7) + 7(2x + 7)\\4x^2 + 28x + 49 = (2x+7)(2x+7)$

Thus, the completely factored form of 4x^2 + 28x + 49 is given by: Option C: (2x+7)(2x+7)

Answer:

Female=14 male=6

Step-by-step explanation:

Oof this toke long I understand it now, for yesterday you gotta do 6+6+6+6+6=30 this is the male and so you add 14 to 30=44, now comes the important part of solving this problem. For today you gotta add 4 men and 4 women so you do 6+6+6+6=24 now 14+14+14+14=56 and if you add 56+24=80 .
