Answer:

x ≈ 3.4 mm

Step-by-step explanation:

using the Sine Rule in the triangle

[tex]\frac{x}{sin27}[/tex] = [tex]\frac{7.1}{sin73}[/tex] ( cross- multiply )

x × sin73° = 7.1 × sin27° ( divide both sides by sin73° )

x = [tex]\frac{7.1sin27}{sin73}[/tex] ≈ 3.4 mm ( to 1 dec. place )

Simplifying

36c2 + -84cd + 49d2 = 0

Reorder the terms:

-84cd + 36c2 + 49d2 = 0

Solving

-84cd + 36c2 + 49d2 = 0

Solving for variable 'c'.

Factor a trinomial.

(6c + -7d)(6c + -7d) = 0

Subproblem 1

Set the factor '(6c + -7d)' equal to zero and attempt to solve:

Simplifying

6c + -7d = 0

Solving

6c + -7d = 0

Move all terms containing c to the left, all other terms to the right.

Add '7d' to each side of the equation.

6c + -7d + 7d = 0 + 7d

Combine like terms: -7d + 7d = 0

6c + 0 = 0 + 7d

6c = 0 + 7d

Remove the zero:

6c = 7d

Divide each side by '6'.

c = 1.166666667d

Simplifying

c = 1.166666667d

Subproblem 2

Set the factor '(6c + -7d)' equal to zero and attempt to solve:

Simplifying

6c + -7d = 0

Solving

6c + -7d = 0

Move all terms containing c to the left, all other terms to the right.

Add '7d' to each side of the equation.

6c + -7d + 7d = 0 + 7d

Combine like terms: -7d + 7d = 0

6c + 0 = 0 + 7d

6c = 0 + 7d

Remove the zero:

6c = 7d

Divide each side by '6'.

c = 1.166666667d

Simplifying

c = 1.166666667d

Solution

c = {1.166666667d, 1.166666667d}

Answer:

Notebook $1.25

Binder $3.20

Step-by-step explanation:

5n + 6b = 25.45

4n + 8b = 30.6

Multiply the first equation by -4.

Multiply the second equation by 5.

Add the equations.

-20n - 24b = -101.8

20n + 40b = 153

16b = 51.2

b = 3.2

5n + 6(3.2) = 25.45

5n + 19.2 = 25.45

5n = 6.25

n = 1.25

Answer:

height = 1/2 ft

Step-by-step explanation:

area of rectangle = width × height

Given:

⇒ 5/6 = 5/3 × height

⇒ height = 5/6 ÷ 5/3

⇒ height = 5/6 × 3/5

⇒ height = 15/30

⇒ height = 1/2 ft

Answer:

  25

Step-by-step explanation:

When we write expressions for the total cost of each field visit and set them equal, we find the solution to be the ratio of the difference in fixed cost to the difference in variable cost.

  y = 75 +7x . . . . . cost for x students to visit the science center

  y = 50 +8x . . . . cost for x students to visit the natural history museum

__

Subtracting the first equation from the second, we get ...

  0 = -25 +x

  25 = x . . . . . add 25; the number of students such that costs are equal

The cost will be the same either place for 25 students.

__

Additional comment

Here, the fixed cost difference is 75-50=25, and the variable cost difference is 8-7=1. The ratio of these costs is ...

  $25/($1 /student) = 25 students.

This relationship only holds when the higher fixed cost is associated with the lower variable cost. Charges are such that one place caters to larger numbers of students (science center), and one prefers fewer students (natural history museum).

The factor of the given equation will be  [tex](12+7x)(12-7x)[/tex]

The given expression is

[tex]=144-7x^2[/tex]

Now we can also write this

[tex]=(12^2-7x^2)[/tex]

By using the formula

[tex](a^2-b^2)=(a+b)(a-b)[/tex]

Now form the above formula

[tex]=(12+7x)(12-7x)[/tex]

Thus the factor of the given equation will be  [tex](12+7x)(12-7x)[/tex]

Hope this helps!

Please give brainliest, i need 3 more :)

Answer:

24.3

Step-by-step explanation:

Here we need to evaluate,

[tex]\longrightarrow 3^3 +14.7\div 7-(1.2\times 4)[/tex]

First of all we need to know about BODMAS , which stands for ,

This means first we need to solve brackets , then of , then division , then multiplication, then addition and finally subtraction.

In the given questions, firstly solve the terms inside the brackets ,

[tex]\longrightarrow 3^3 +14.7 \div 7 -(1.2\times 4)[/tex]

Multiply 1.2 and 4 ,

[tex]\longrightarrow 3^3+14.7\div 7-(4.8) [/tex]

Now perform division , that is divide 14.7 by 7

[tex]\longrightarrow 3^3 + 2.1 - 4.8 [/tex]

Simplify 3³ .

[tex]\longrightarrow (3)(3)(3)+2.1-4.8= 27+2.1-4.8[/tex]

Add ,

[tex]\longrightarrow 29.1 -4.8[/tex]

Finally subtract,

Hi! Hope this helps

(- stands for negative and + stands for positive)

Adding

- plus + = - or + depending on the numbers (If you have -7 + 3 it equals -4, but -3 + 7 = 4)

+ plus + = + (Simple)

- plus - = - (Like regular addition, except -2 + -3 would be -5)

Subtraction

- minus + = - (If you have -7 - 3 it equals -10, and -3 - 7 = -10)

- minus - = + (If you have -3 - (-4) = 1)

+ minus + = - or + depending on the numbers ( If you have 8 - 4 it equals 4, but if you subtract 8 from 4, it is -4
