Answer:

x = 52

Step-by-step explanation:

This is a picture of a right angle, which is 90 degrees. We should first make an equation to represent this problem.

(x - 12) + 50 = 90

1. Subtract 50 from both sides of the equation.

(x - 12) = 40

2. Add 12 from both sides of the equation

x = 52

The value of x is 52.

Answer:   [tex]w \le 3000[/tex]

w is the weight of the truck in pounds.

Since w cannot be negative, we can write [tex]0 \le w \le 3000[/tex] or we could tack on the statement "w must be positive"

The phrase "at most" means "that is the largest w can get". Think of it as the ceiling.

We are given that:

Area of rectangle is given by:

[tex] \implies\quad{\pmb{ \sf{Area = length\times width}} }[/tex]

Hence, putting the values in the formula:

[tex] \implies\quad \sf{ A = l\times w}[/tex]

[tex] \implies\quad \sf{ 30\sqrt{3750}=3\sqrt{250}\times w}[/tex]

[tex] \implies\quad \sf{3\sqrt{250}\times w = 30\sqrt{3750} }[/tex]

[tex] \implies\quad \sf{ w =\dfrac{30\sqrt{3750}}{3\sqrt{250}}}[/tex]

[tex] \implies\quad \sf{ w =10\dfrac{\sqrt{3750}}{\sqrt{250}}}[/tex]

[tex] \implies\quad \sf{ w = 10\times\sqrt{\dfrac{3750}{250}}}[/tex]

[tex] \implies\quad \underline{\underline{\pmb{\sf{ w =10\sqrt{15}}}}}[/tex]

Answer:

Midpoint = [tex](\frac{1}{2},\frac{1}{2} )[/tex]

Step-by-step explanation:

Let's solve your equation step-by-step.

x2−2x+1=4

Step 1: Subtract 4 from both sides.

x2−2x+1−4=4−4

x2−2x−3=0

Step 2: Factor left side of equation.

(x+1)(x−3)=0

Step 3: Set factors equal to 0.

x+1=0 or x−3=0

x=−1 or x=3

Answer:

x=−1 or x=3

Answer:

There are 163 whiteboards undamaged.

Step-by-step explanation:

So first we know that 12 are damaged and there are 172 students. So first we need to find out how many whiteboards did you buy without knowing there will be 12 damaged. The answer is 7 because there are 25 per pack. And 7 * 25 = 175. You can't buy less because you rather buy extra rather then not enough. Now knowing that, what is 175 - 12 because 12 was damaged.

175 - 12 = 163.

There are 163 whiteboards undamaged.

163 white boards are undamaged

Given;

172 Students

25 in a pack

12 whiteboards are damaged

To Find;

How many whiteboards are undamaged?

Solution;

we need 172 whiteboard but one pack consist of 25 whiteboards

⇒ 172/25 = 6.88

≈ 7 pack

Total whiteboard we buy

⇒ 7 × 25 = 175

Out of which 12 whiteboard are damaged

↓ Undamaged whiteboard ↓

→ 175 - 12 = 163 ←

thus, 163 whiteboards are undamaged

Answer:

15, the second one.

Step-by-step explanation:

We can use this proportion:

[tex]\frac{centimeters}{meters}[/tex]

So, in this case:

[tex]\frac{5 centimeters}{20 meters}[/tex]=[tex]\frac{x centimeters}{60 meters}[/tex]

We can cross multiply, resulting in:

[tex]20x = 300 centimeters[/tex]

Divide both sides by 20, resulting in:

If two people shared three hamburgers then each person would get one hamburger and a half. Since there are two people and three hamburgers, both people can get one hamburger and split the third. In decimal form, It would be 1.5

Answer:

The answer is 3 because 6÷2 which equal 3 which is represent the three hameburgers and 6÷2=3 because there would be 6 hamburgers to share between two people.

Answer:

a) The answer is: (x + a, y + b)

b) The answer is: (-1, -2)

The initial coordinates are:

(x, y) = (-2, -5)

Let's find a and b.

a is a distance in x direction: a = 1

b is a distance in y direction: b = 3

The final position is:

(x + a, y + b) = (-2 + 1, -5 + 3) = (-1, -2)

Step-by-step explanation:

Answer:

slope m = (y₂ - y₁) / (x₂ - x₁)

             = (8 - 1) / (5 - (-5))

          m = 7/10

y-intercept using slope above and anyone of given point. Let's use (-5, 1):

  y = mx + b

  1 = 7/10(-5) + b

  1 = -35/10 + b

  b = 45/10

  b = 9/2

Equation of line:

y = mx + b

y = 7/10x + 9/2

Point slope form:

y - y₁ = m(x - x₁)

y - 1 = 7/10(x - (-5))

y - 1 = 7/10(x + 5)

Here's how we classify polynomials:

More Information:

A polynomial with 1 term is called a monomial (for example, 6d)

A polynomial with 2 terms is called a binomial (for example, 6d+ 2a)

A polynomial with 3 terms is called a trinomial (for example, 6d+2a-4s)

A polynomial with 4 or more terms is called a polynomial

(for example. 6d+2a-4s+3e-t+9k-12a)

Degree: first, second, third.. depends on the exponent.

Hence, -2 is
