Which expression is equivalent to (5x - 4)2?

Answers

Answer 1

Answer:

Step-by-step explanation:

the answer is 25x^2-40x+16

Answer 2

25x^2-40x+16 is equivalent to (5x - 4)^2.

What is  multiplication?

In mathematics, multiplication is a method of finding the product of two or more numbers. It is one of the basic arithmetic operations, that we use in everyday life.

here, we have,

(5x - 4)^2

we know,

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

by using this, we get,

(5x - 4)^2

=5x*5x-2*5x*4+4*4

=25x^2-40x+16.

Hence, 25x^2-40x+16 is equivalent to (5x - 4)^2.

Answers

Answer:

y=1/3x+11/3

Step-by-step explanation:

y=mx+b

y=1/3x+b

3=1/3(-2)+b

3 = -2/3+b

+2/3 +2/3

11/3=b

So the equation of the line that perpendicular to y= -3x + 3/5 that Goes through point (-2, 3 ) is y=1/3x+11/3.

X varies directly as the cube root of y .x=6when y=8.Find the value of x when y=64.

Answers

Answer:

The value of x is 12.

Step-by-step explanation:

Given that x is directly proportional to y so the expression will be x = k (³y) where k is the constant. First, you have to find the value of k :

[tex]x = k \: (\sqrt[3]{y} )[/tex]

[tex]let \: x = 6,y = 8[/tex]

[tex]6 = k \: (\sqrt[3]{8} )[/tex]

[tex]6 = k(2)[/tex]

[tex]k = 3[/tex]

Next, you have to find the value of x, by substituting y = 64 into the expression :

[tex]x = 3 \: ( \sqrt[3]{y} )[/tex]

[tex]x = 3( \sqrt[3]{64} )[/tex]

[tex]x = 3(4)[/tex]

[tex]x = 12[/tex]

At Escobar Middle School, 5% of sixth-grade students, which is 20 students, are enrolled in both art and choir. How many sixth-grade students are there in total

Answers

Answer:

If 20 is 5% multiplying it by 20 would give us 100%, so 20*20=400. There are 400 sixth-grade students in total.

The total number of sixth-grade students at Escobar Middle School is 400 students

What is Percentage?

A percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, %

Given data ,

Let the total number of students in sixth grade = x

5 % of sixth grade students is = 20 students

So ,

We need to calculate the total 100 % students in the sixth-grade

And ,

10 % of sixth-grade students = 2 x 5 % of sixth grade students

                                               = 2 x 20 students

                                               = 40 students

Now ,

100 % of sixth-grade students x = 10 x 10 % of sixth-grade students

                                                    = 10 x 40 students

                                                    = 400 students

Therefore , there are 400 students

Hence , the total number of sixth-grade students is 400 students

the 15% tip on craig's lunch bill came to $2.40 what was the amount of bill before the tip? show workouts​

Answers

Since the tip is 15% of some cost x, we can calculate that.
Remember to write the percent as a decimal for the calculations
Think of the tip as the question 2.40 is 15% of what number?

2.40/x = 15/100
Multiply both sides by x
2.40 = 15x/100
2.40 = 0.15x

So the tip 2.40 = 0.15x
Divide both sides 0.15 to solve for x
And that makes the cost before the tip 2.40/0.15 = 16.00
$16.00
The total bill for his lunch would be the cost before the tip plus the tip

We can calculate the final bill as $16.00 + $2.40 = $18.40

Y values increase by 4, X values increase by 1.

M or slope, = 4/1 or 4

Y-intercept is when x = 0

When x = 0 in this case, y = 1.

So,

y = 4x +1

Answer:

y = 4x + 1

Step-by-step explanation:

This is the y = mx + b format, hopefully its useful for you! It's a linear equation because all the values grow at a constant rate.

The y-intercept is 1 and it's rise over run which means that you start at 1 on your y-intercept when graphing and then rise 4 and run 1 to the right because it's a positive slope.

Determinar que Recipiente tiene mayor densidad; el recipiente A pesa 1.2 toneladas y tiene un volumen de 120 m³ mientras que el recipiente B pesa 2.4 toneladas y tiene un volumen de 240 m³. ¿Cuál recipiente tiene mayor densidad?

Answers

Answer:

Ambos recipientes tienen la misma densidad, es decir, 10 kilogramos por metros cúbicos.

Step-by-step explanation:

Recordamos que la densidad de un material uniforme ([tex]\rho[/tex]), medido en kilogramos por metro cúbico, está definido por:

[tex]\rho = \frac{m}{V}[/tex] (1)

Donde:

[tex]m[/tex] - Masa, medido en kilogramos.

[tex]V[/tex] - Volumen, medido en metros cúbicos.

Ahora calculamos la densidad de cada recipiente:

Recipiente A ([tex]m =1200\,kg[/tex], [tex]V = 120\,m^{3}[/tex])

[tex]\rho = \frac{1200\,kg}{120\,m^{3}}[/tex]

[tex]\rho = 10\,\frac{kg}{m^{3}}[/tex]

El recipiente A tiene una densidad de 10 kilogramos por metro cúbico.

Recipiente B ([tex]m = 2400\,kg[/tex], [tex]V = 240\,m^{3}[/tex])

[tex]\rho = \frac{2400\,kg}{240\,m^{3}}[/tex]

[tex]\rho = 10\,\frac{kg}{m^{3}}[/tex]

El recipiente B tiene una densidad de 10 kilogramos por metro cúbico.

Ambos recipientes tienen la misma densidad, es decir, 10 kilogramos por metros cúbicos.

Answers

Answer:

Step-by-step explanation:

4% teenagers --> 120 teenagers were there

120/4 means 1% so 30 is 1%

1% times 100 is 100% so 30 times 100 equals 100% so 3000 is 100% of the people at the stadium
