Step-by-step explanation:

SOHCAHTOA

sinθ = opposite / hypotenuse

cosθ = adjacent / hypotenuse

tanθ = opposite / adjacent

10. tan64° = 42 / x ; x = 42 / tan64° ; x = 20.48476872

12. sin54° = BD / 20 ; BD = 20 * sin54° ; BD = 16.18033989 ;

     tan28° = BD / DC ; DC = BD / tan28° ; DC = 30.43079344

13. tan51° = JL / 14 ; JL = 14 * tan51° ; JL = 17.28856019 ;

     cos72° = KL / JL ; KL = JL * cos72° ; KL = 5.342458907

Answer:

Shipping Fee = $ 6

Step-by-step explanation:

The complete question and the table is as follows :

Given - Julio is ordering books from Best Books for his reading club. The table shows Julio's total cost of the book order, Including the shipping fee for each order. Best Books charges the same shipping fee for every book order.

To find - How much is the shipping fee?

Proof -

We know that,

Total Cost = (Number of books buy)(Cost of 1 book) + Shipping Fee

Let us Assume that,

Cost of 1 book = x

Shipping Fee = y

So,

From the table, we get

21 = 5x + y               ..........(1)

36 = 10x + y              ..........(2)

51 = 15x + y               ..........(3)

66 = 20x + y             ..........(4)

From equation (1), we get

y = 21 - 5x

Put the value of y in equation (2), we get

36 = 10x + 21 - 5x

⇒36 = 5x + 21

⇒5x = 36 - 21

⇒5x = 15

⇒x = [tex]\frac{15}{5}[/tex] = 3

∴ we get

x = 3

Put the value of x , we get

y = 21 - 5(3)

  = 21 - 15

  = 6

⇒y = 6

SO, we get

x = 3

y = 6

Verify the 4 Equations :

21 = 5x + y               ..........(1)

21 = 5(3) + 6

    = 15 + 6

    = 21

⇒21 = 21

Verified

36 = 10x + y              ..........(2)

36 = 10(3) + 6

     = 30 + 6

     = 36

⇒36 = 36

Verified

51 = 15x + y               ..........(3)

51 = 15(3) + 6

    = 45 + 6

    = 51

⇒51 = 51

Verified

66 = 20x + y             ..........(4)

66 = 20(3) + 6

     = 60 + 6

     = 66

⇒66 = 66

Verified

So, we get

Cost of 1 book = x = $ 3

Shipping Fee = y = $ 6

Answer:

0.82

Step-by-step explanation:

100 has 2 zeros so you move the decimal 2 places to the left.

82.

8.2

0.82

Answer:

0.82

Step-by-step explanation:

Decimals are out of 100, this fraction, 82/100, is also out of one hundred; this makes the question much easier to solve.  Just take the numerator and put it as a decimal, so in this case, the numerator is 82. We take that numerator and make it a decimal: 0.82.

Answer:

c. 6

Step-by-step explanation:

Given

See attachment for graph

Required

Average rate of change

This is calculated as:

[tex]Rate = \frac{f(b) - f(a)}{b - a}[/tex]

Where

[tex](a,b) = (2,4)[/tex]

So, we have:

[tex]Rate = \frac{f(4) - f(2)}{4 - 2}[/tex]

[tex]Rate = \frac{f(4) - f(2)}{2}[/tex]

Using the attached graph, we have:

[tex]f(2) = 4[/tex]

[tex]f(4) = 16[/tex]

So, we have:

[tex]Rate = \frac{16- 4}{2}[/tex]

[tex]Rate = \frac{12}{2}[/tex]

[tex]Rate = 6[/tex]

Answer:

Whereas the basic formula for the area of a rectangular shape is length × width, the basic formula for volume is length × width × height.

Step-by-step explanation:

Answer:

SA = 2(Area of Trapezoid) + 2(Area of Rectangle) + Area of Base + Area of Top

SA = 2 ( 10cm + 6cm)(7cm) + 2(16cm x 8cm) + (16cm x 10cm) + (16cm x 8cm)

                        2

SA = 112 cm2 + 256 cm2 + 160 cm2 + 128 cm2

SA = 656 cm2 wrapping paper you need

okay, the answer to this question is listed below;

for a it says that half pupils choose maths.

And as you can see the results in the circle that it is true.

for the question c it says most pupils choose science that PE, as you can see the the circle that PE is a little more than science, so this Answer is false

Answer:

ST = 4

Step-by-step explanation:

A segment joining the midpoints of 2 sides of a triangle is half the length of the third side.

ST = [tex]\frac{1}{2}[/tex] PQ substitute values

- 32 + 9x = [tex]\frac{1}{2}[/tex] (- 5x + 28) ← multiply both sides by 2 to clear the fraction

- 64 + 18x = - 5x + 28 (add 5x to both sides )

- 64 + 23x = 28 ( add 64 to both sides )

23x = 92 ( divide both sides by 23 )

x = 4

Then

ST = - 32 + 9x = - 32 + 9(4) = - 32 + 36 = 4

Answer:

0-6 de correct answer okay.

At x→ -3 the value of the limit of function g(x) does not exist because the left-hand limit and right-hand limit are not equal an option second is correct.

A limit is a value at which a function approaches the output for the given values in mathematics. Limits are used to determine integrals, derivatives, and continuity in calculus and mathematics.

We have a graph of function g(x)

[tex]\rm \lim_{x \to a}g(x)[/tex]

Let's check at x = -3

Finding the left-hand limit and right-hand limit.

[tex]\rm \lim_{x \to -3^{-1}}g(x) = -2[/tex]

[tex]\rm \lim_{x \to -3^{+1}}g(x) = -4[/tex]

Since the left-hand limit and right-hand limit are not equal then at x = -3 the limit does not exist.

Thus, at x→ -3 the value of the limit of function g(x) does not exist because the left-hand limit and right-hand limit are not equal an option second is correct.

Answer:

First option is correct

"The sum of two numbers is 20" can be translated mathematically into the equation:

x + y = 20.

"... and their difference is 10" can be translated mathematically as:

x - y = 10

We can now find the two unknown numbers, x and y, because we now have a system of two equations in two unknowns, x and y. We'll use the Addition-Subtraction Method, also know as the Elimination Method, to solve this system of equations for x and y by first eliminating one of the variables, y, by adding the second equation to the first equation to get a third equation in just one unknown, x, as follows:

Adding the two equations will eliminate the variable y:

x + y = 20

x - y = 10

-----------

2x + 0 = 30

2x = 30

(2x)/2 = 30/2

(2/2)x = 15

(1)x = 15

x = 15

Now, substitute x = 15 back into one of the two original equations. Let's use the equation showing the sum of x and y as follows (Note: We could have used the other equation instead):

x + y = 20

15 + y = 20

15 - 15 + y = 20 - 15

0 + y = 5

y = 5

CHECK:

In order for x = 15 and y = 5 to be the solution to our original system of two linear equations in two unknowns, x and y, this pair of numbers must satisfy BOTH equations as follows:

x + y = 20 x - y = 10

15 + 5 = 20 15 - 5 = 10

20 = 20 10 = 10

Therefore, x = 15 and y = 5 is indeed the solution to our original system of two linear equations in two unknowns, x and y, and the product of the two numbers x = 15 and y = 5 is:

xy = 15(5)

xy = 75
