i need help pls!
this test is about angles, and i am having trouble with it.

Answer:

35 square units

Step-by-step explanation:

take the amount of each side and multiply. so it would be 5 times 7. that gives you the total area.

Answer:

Your answer is 35!

Step-by-step explanation:

You just count the squares along the sides of the rectangle. Since you need length and width to find area, you count the bottom side and one of the sides. Then multiply! Or just count the squares inside the rectangle :)

Answer:

Kindly check explanation

Step-by-step explanation:

Given the data:

Before _After_ diff ___rank

72 ______ 59 __13 __ 2

74 _______ 72 _ 2 __ 7

62 _____ 89 __ - 27 _ 1

74 _______ 67 __ 7 __4

78 ______ 81 __ - 3 __ 6

88 ______ 92 __ - 4 __5

71 _______ 81 __ - 10 __3

Ranking the data:

27, 13, 10, 7, 4, 3, 2

Observation 5 :

Before = 78 ; After = 81

Difference ; 78 - 81 - 3

Observation 5 = Rank 6

Ranks with negative difference, T = 6 + 5 + 3 + 1 = 12

Ranks with negative difference T+ = (2 + 7 + 4) = 13

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.

its CL i think im very sorry if im wrong

Answer:

The answer for A is A- 3.75

And the answer for B is B- 16

Answer:

30°

Step-by-step explanation:

4x-12 = 108

4x = 120

x=30

4(30)-12 = 108 (Just to check)

120-12 =108

108=108

Answer:

Step-by-step explanation:

As,

[tex] {(ax)}^{2} = a \times a \times x \times x[/tex]

Hence,

[tex] {(2x)}^{2} [/tex]

= 2×2×x×x

[tex] = 4 {x}^{2} (ans)(without \: brackets)[/tex]

Hope this helps!! :)

Answer:

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

Step-by-step explanation:

Answer:

3,000,000

Step-by-step explanation:

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:

20.5 , 30.4 , 5.3

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:

Step-by-step explanation:

The marked angles share a vertex and are formed from opposite rays. They do not share a side, so are not adjacent angles. The angles are vertical angles.

As such, they are congruent, so x = 87°.

Answer:

In geometry, the area can be defined as the space occupied by a flat shape or the surface of an object. The area of a figure is the number of unit squares that cover the surface of a closed figure. Area is measured in square units such as square centimteres, square feet, square inches, etc.

Answer:

First option is correct

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:

x is 5

Step-by-step explanation:

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:

f(x)=x5-x4+9

if x=2,. f(2)= 2⁵-2⁴+9

=32-16+9

=16+9

f(2) =25

Answer:

Step-by-step explanation:

We can let P and L represent the hourly costs of packing and loading, respectively. The two estimates can be represented by the equations ...

  6P +5L = 675

  4P +3L = 425

The LCM of the coefficients of P is LCM(6, 4) = 12.

The LCM of the coefficients of L is LCM(5, 3) = 15.

__

Each LCM is the product of the numbers, divided by their greatest common factor. For 4 and 6, the product is 24, and both even numbers have a factor of 2, so the LCM of 4 and 6 is 24/2 = 12. The numbers 3 and 5 have no common factors, so the LCM is simply their product.

_____

The LCM is useful if you're going to solve the equations by "elimination". Here, the LCM of 12 means we can eliminate P by making its coefficient be 12 in both equations. Multiplying the first equation by 2, we can subtract 3 times the second equation to eliminate P:

  2(6P +5L) -3(4P +3L) = 2(675) -3(425)

  12P +10L -12P -9L = 1350 -1275

  L = 75 . . . . . simplify

Similarly, we can eliminate L by making its coefficients be 15.

  5(4P +3L) -3(6P +5L) = 5(425) -3(675)

  20P +15L -18P -15L = 2125 -2025

  2P = 100 . . . . simplify

  P = 50 . . . . . . divide by 2

The hourly rates are ...

  $50 per hour for packing

  $75 per hour for loading

Answer:

40 packing and 80 moving

Answer:

3.2 hours

Step-by-step explanation:

48x4=192

192 divided by 60 is 3.2

Answer:

3 hours and 12 minutes

Step-by-step explanation:

there are 15 sets of 4 in one hour, so 15 plus 15 equals 2 hours or 30 braids. Then you add one more hour and you get 45 braids and then for the last three braids its 12 minutes
