Use the extended form find the perimeter of the square shape of 10cm and 18cm

Answer:

n = 3.8

Step-by-step explanation:

First, we would distribute 0.3 with n and 1.5.

0.3(n - 5) = 0.4 - 0.2n → 0.3n - 1.5 = 0.4 - 0.2n

Next, we can move the number with the variable to one side.

0.2n + 0.3n - 1.5 = 0.4 - 0.2n + 0.2n → 0.2n + 0.3n - 1.5 = 0.4

(Because we added 0.2n to the negative 0.2n on the right side, it cancels it out)

We can also move 1.5 to the right side of the equation as well.

0.2n + 0.3n - 1.5 + 1.5 = 0.4 + 1.5 → 0.2n + 0.3n = 0.4 + 1.5

Then, we combine like terms

0.2n + 0.3n = 0.5n & 0.4 + 1.5 = 1.9 → 0.5n = 1.9

Finally, we divide both sides by 0.5.

n = 3.8

Answer:

-93

Step-by-step explanation:

Step one:

given the expressions

[tex]f(x) = -4x + 7\\\\g(x) = 2x^2 + 5x- 8[/tex]

we want (fog)(-3).

but (fog) is

[tex]f(x) = -4x + 7\\\\\ (fog)=-4(2x^2 + 5x -8) + 7\\\\ (fog)=-8x^2-20x+32+7[/tex]

Step two:

fog(-3)= put x= -3 in (fog)(-3)=-8x^2-20x+32+7

[tex](fog)(-3)=-8x^2-20x+32+7\\\\ (fog)(-3)=-8(-3)^2-20(-3)+32+7\\\\ (fog)(-3)=-8*9+60+32+7\\\\ (fog)(-3)=-72-60+32+7\\\\ (fog)(-3)=-93[/tex]

Step-by-step explanation:

A star is 2.3 x 10^2 light years away

We know that one light year is about 5.9 x 10^12 miles away

So, we know the star is 2.3 x 10 ^2 x 5.9 x 10^12 = 13.57 x 10^14 = 1.357 x 10^14

Answer:

Actually, there are two. They are the Parallelogram Opposite Sides Theorem and the Parallelogram Opposite Angles Theorem.

Step-by-step explanation:

POST means that if opposite sides of a quadrilateral are the same, it's a parallelogram.

POAT means that if opposite sides of a quadrilateral are the same, it's a parallelogram.

A quadrilateral has to meet both of these theorems to be a parallelogram.

Answer:

B

Step-by-step explanation:

The equation that can be used to solve for 'a' is a/sin35° = 30/sin60°.

A triangle is a three-sided closed-plane figure form by joining three noncolinear points. Based on the side property triangles are of three types they are Equilateral triangle, Scalene triangle, and Isosceles triangle.

We know sine rule of triangles which states,

a/sinA + b/sinB + c/sinC.

We also know that the sum of all the interior angles in a triangle is 180°.

Therefore, The measure of angle B is 180° - (35 + 85)°.

= 60°.

So, The equation can you use to solve for 'a' would-be,

a/sin35° = 30/sin60°.

asin60° = 30sin35°.

(√3/2)a = 30×0.5735.

a = (30×0.5735)/0.866.

a = 17.205/0.866.

a = 19.87.

Step-by-step explanation:

Given

Is the given info enough to find the equation?

Yes, it is enough and the proof is as follows:

And equation is solved using:

Where

[tex](x_1,y_1) = (6,-2)[/tex]

[tex]m = -3[/tex]

Substitute these values in [tex]y - y_1 = m(x - x_1)[/tex]

[tex]y - (-2) = -3(x - 6)[/tex]

[tex]y +2 = -3(x - 6)[/tex]

Answer:

90%

Step-by-step explanation:

1. We assume, that the number 5400 is 100% - because it's the output value of the task.

2. We assume, that x is the value we are looking for.

3. If 100% equals 5400, so we can write it down as 100%=5400.

4. We know, that x% equals 6000 of the output value, so we can write it down as x%=6000.

5. Now we have two simple equations:

1) 100%=5400

2) x%=6000

where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:

100%/x%=5400/6000

6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 6000 is what percent of 5400

Answer:

0.25x -12= 18- 0.55x (subtract 0.25x from both sides)

-12= 18 -0.80x (subtract 18 from both sides)

-30= -0.80x (divide each side by -0.80)

x= 37.5 (this is your answer)

The value of x in which the two expressions have the same value is 37.5

Here,

Given that;

Two expressions are,

Expression 1 :   0.25x - 12

Expression 2:   18- 0.55x

We have to find the value of x.

What is Mathematical expression?

A sentence with a minimum of two numbers or variables and at least one math operation is present, is called Mathematical expression.

Now,

The value of x will be find after equating both expressions as;

0.25x - 12 = 18 - 0.55x

Subtract 0.25x from both sides, we get;

- 12 = 18 - 0.80x

Subtract 18 from both side, we get;

- 30 = - 0.80x

Divide each side by -0.80, we get;

x= 37.5

Hence, The value of x in which the two expressions have the same value is 37.5

The Native American population in state A and B is 282,000 and 94,000 respectively.

Here, we are given that State A's population of Native Americans is three times the Native American population of State B.

Let the Native American population in state B be x

Thus, the Native American population in state A will be 3x

Total Native American population in state A and B = 376,000

Thus, we can get the following equation-

x + 3x = 376,000

4x = 376,000

x = 376,000/ 4

x = 94,000

⇒ 3x = 3 × 94,000

3x = 282,000

Thus, the Native American population in state A and B is 282,000 and 94,000 respectively.

Answer:

The smallest angle is 30 degrees, the second angle is 80 degrees and the third angle is 70 degrees

Step-by-step explanation:

let x = the smallest angle

This means that one angle is x+40, and the third angle is 3x-10. This make our equation:

x + 40 + 3x - 10 + x = 180

Combine like terms

5x + 30 = 180

Subtract 30 from both sides

5x = 150

Divide both sides by 5

x = 30
