The first 4 (.4) is 10x bigger than the second 4 (.04)

Answer:

The given number is 3.441

The first 4 is in the tenth place that is written like $\frac{4}{10}$ or 0.4

The second 4 is in the hundredth place that is written like $\frac{4}{100}$ or 0.04

We can see that the second 4 is one tenth times the first 4. This is shown like = $\frac{1}{10} \times\frac{1}{10}$ = $\frac{1}{100}$

Or we can say the opposite that the first 4 is ten times the second 4.

If 40% of a number is 80 what is 25% of that number?

olga2289 [7]

Answer:

25% of 200 is 50

Step-by-step explanation

40% of a number is 80

.40 * n = 80

Divide each side by .4

.40 n/.4 = 80/.4

n = 200

The number is 200

Now lets find 25 percent of that number

.25 * 200 = 50

How do I do this? I’m so confused

Shtirlitz [24]

I say left because you have a straight line, i goes through 0,0 and every time it goes over 1 and up by 3.

Find the constant $a$ such that\[(x^2 - 3x + 4)(2x^2 +ax + 7) = 2x^4 -11x^3 +30x^2 -41x +28.\]

Colt1911 [192]

The value of constant a is -5

Further explanation:

We will use the comparison of co-efficient method for finding the value of a

So,

Given

$(x^2 - 3x + 4)(2x^2 +ax + 7)\\= x^2((2x^2 +ax + 7)-3x((2x^2 +ax + 7)+4(2x^2 +ax + 7)\\= 2x^4+ax^3+7x^2-6x^3-3ax^2-21x+8x^2+4ax+28\\Combining\ alike\ terms\\=2x^4+ax^3-6x^3+7x^2-3ax^2+8x^2-21x+4ax+28\\= 2x^4 +(a-6)x^3+(15-3a)x^2-(21-4a)x+28\\$

As it is given that

(x^2 - 3x + 4)(2x^2 +ax + 7) = 2x^4 -11x^3 +30x^2 -41x +28

In this case, co-efficient of variables will be equal, so we can compare the coefficients of x^3, x^2 or x

Comparing coefficient of x^3

$a-6 = -11\\a = -11+6\\a = -5$

So the value of constant a is -5

Which equations represent the line that is parallel to 3x − 4y = 7 and passes through the point (−4, −2)? Check all that apply.

DIA [1.3K]

Reta a:

$3x-4y=7 \\ -4y=-3x+7 \\ 4y=3x-7 \\ y= \frac{3}{4}x- \frac{7}{4}$

reta x:

$y=ax+b$

Retas paralelas possuem coeficientes angulares iguais ⇒ mₐ=mₓ

$y= \frac{3}{4}x+b$

(-4,-2)

$\frac{3}{4}.(-4)+b=-2 \\ -3+b=-2 \\ b=-2+3 \\ b=1$

∴ y=3/4x+1
