If 35% of a number is 84 and 60% of the same number is 144, find 25% of that number.

Answer:

x^2 - 12x = -27

Step-by-step explanation:

Here, we want to isolate the constant for the polynomial

To do this, we start by setting the expression to zero

Afterwards, we can bring the constant term over the equal to sign, giving a change in sign value

Mathematically, we have this as;

x^2 - 12x + 27 = 0

x^2 - 12x = -27

Answer:

There are two ways to find the rational number between any two numbers. I will tell you an easy method to find it.

As we have to find 5 rational numbers between 1 & 2

Take 5 and add 1 to it i.e. 5+1= 6

Now take the first number and multiply and divide it by 6 i.e.

1x6/6 = 6/6

Also take the second number and multiply and divide it by 6 i.e.

2x6/6= 12/6

This is done to convert 1 & 2 into rational number i.e. in form of p/q

Now we have two numbers 6/6 and 12/6 so five rational numbers between them are

7/6, 8/6, 9/6, 10/6, 11/6

The values of these number you can check will be between 1 & 2. Actually between any two number there are infinite number of rational numbers.

Answer: Well if you buy a pack of socks with 15 for $9 you are not getting the best deal over buying a pack of socks with 20 for $11. The reason behind this is because each sock is worth $0.6 meaning that you are only paying two extra dollars for five socks which would have normally cost $3. Shawn (with the 20 pack) is saving $1.

Given:

Consider the population of California = [tex]3.9\times 10^7[/tex]

Consider the population of Maine = [tex]1.3\times 10^6[/tex]

To find:

The difference between the population of California and Maine.

Solution:

We have,

Population of California = [tex]3.9\times 10^7[/tex]

Population of Maine = [tex]1.3\times 10^6[/tex]

Difference between the population of California and Maine is

[tex]\text{Difference}=3.9\times 10^7-1.3\times 10^6[/tex]

[tex]\text{Difference}=3.9\times 10^7-(0.13\times 10)\times 10^6[/tex]

[tex]\text{Difference}=3.9\times 10^7-0.13\times 10^7[/tex]

[tex]\text{Difference}=(3.9-0.13)\times 10^7[/tex]

[tex]\text{Difference}=3.77\times 10^7[/tex]

Therefore, the correct option is D.

Answer:

one solution: (1.-4)

Step-by-step explanation:

y = 2x - 6...... (1)

y = -x-3......(2)

Plug y = -x-3 in equation (1)

2x - 6 = - x - 3

2x + x = 6 - 3

3x = 3

x = 3/3

x = 1

Plug x = 1 in equation (2)

y = - 1 - 3

y = - 4

(x, y) = (1, - 4)

Answer:

  False

Step-by-step explanation:

Corresponding angles in similar triangles are congruent. The similarity statement tells you angle B corresponds to angle Y, so those angles are congruent. The sines of congruent angles are identical.

  sin(B) > sin(Y) . . . . FALSE

  sin(B) = sin(Y) . . . . true

Answer:

12 ft²

Step-by-step explanation:

the rectangular hole area:

l • w = A

3 • 2 = 6 ft

the triangular hole area:

(b • h) / 2 = A

(4 • 3) / 2 = 6 ft

6 ft + 6 ft = 12 ft²

Answer:

2,370 mL

Step-by-step explanation:

1000mL = 1 L, so I multiplied 1000 by 2.37

If they ask for it to be set up as a proportion, I would write 1/1000 = 2.37/x and cross multiply. x = 2,370

Given:

The vertices of a rectangle are (6, 3), (−6, 3), (−6, −1), and (6, −1).

To find:

The perimeter of the rectangle.

Solution:

Distance formula:

[tex]d=\sqrt{(x_2-x_1)^2-(y_2-y_1)^2}[/tex]

Let the vertices of a rectangle are A(6, 3), B(−6, 3), C(−6, −1), and D(6, −1).

Using the distance formula, we get

[tex]AB=\sqrt{(-6-6)^2-(3-3)^2}[/tex]

[tex]AB=\sqrt{(-12)^2-(0)^2}[/tex]

[tex]AB=\sqrt{144}[/tex]

[tex]AB=12[/tex]

Similarly,

[tex]BC=\sqrt{\left(-6-\left(-6\right)\right)^2+\left(-1-3\right)^2}=4[/tex]

[tex]CD=\sqrt{\left(6-\left(-6\right)\right)^2+\left(-1-\left(-1\right)\right)^2}=12[/tex]

[tex]AD\sqrt{\left(6-6\right)^2+\left(-1-3\right)^2}=4[/tex]

Now, the perimeter of the rectangle is:

[tex]Perimeter=AB+BC+CD+AD[/tex]

[tex]Perimeter=12+4+12+4[/tex]

[tex]Perimeter=32[/tex]

Therefore, the perimeter of the rectangle is 32 units.

Answer:

The first quartile is 26.

The third quartile is 45

The median is 30.5

The interquartile range is 19.

Answer:

The distance around a circle on the other hand is called the circumference (c).

Step-by-step explanation:

A straight line that passes from one side of a circle to the other through the center is called the diameter. The distance around the outside of a circle is called the circumference. All points on the edge of a circle are the same distance to the center.

The length of the outside of a circle is called the "circumference."

The circumference is the total distance around the outer boundary of the circle.

The distance cover while completing one full lap around the track is equivalent to the circumference of the circle.

The formula to calculate the circumference (C) of a circle is:

C = πd

where π (pi) is a mathematical constant equal to 3.14159, and d represents the diameter of the circle.

The formula for circumference in terms of the radius is:

C = 2πr

Answer:

The error in rounding a number is half of the unit of measure. The number was rounded to the nearest 0.1 unit so the error is half of 0.1 which is 12⋅0.1=0.05

⋅0.1=0.05. Since 3.7+0.05=3.753.7+0.05=3.75 and 3.7−0.05=3.653.7−0.05=3.65, then the error interval is \boxed{3.65\le x<3.75}.

Answer:

|x + 7| ≥ 2 is the inequality

Step-by-step explanation:

x - b ≥ c    or    x - b ≤ -c

x ≥ b + c = -5     or x ≤ b - c = -9

b + c = -5

b - c = -9

2b = -14

b = -7                             -7 + c = -5

                                             c = 2

x - (-7) = x + 7

So, |x + 7| ≥ 2 is the inequality
