Step-by-step explanation:

i hope this will help you :)

Answer:

true

Step-by-step explanation:

The sum of exterior angles of a regular polygon are 360°

Answer:

Step-by-step explanation:

1) We would determine the cube root of 27 and find its square.

Cube root of 27 = 3

3² = 9

Solution = 9

2) 36³ = 46656

√36³ = √46656 = 216

3) we would find the 5th roof of - 243 and find its cube

5th root of - 243 = - 3

- 3³ = - 27

Solution = - 27

4) Looking at the expression, 40⅔, we can see that

a = 2

b = 3

c = 40

Answer: 1) We would determine the cube root of 27 and find its square.Cube root of 27 = 33² = 9Solution = 92) 36³ = 46656√36³ = √46656 = 2163) we would find the 5th roof of - 243 and find its cube5th root of - 243 = - 3- 3³ = - 27Solution = - 274) Looking at the expression, 40⅔, we can see that a = 2b = 3c = 40

Answer: about 5 hours and 3 min

Step-by-step explanation:

Answer:

about 8 hours and 7 minutes

Step-by-step explanation:

have 60 minutes divided by 20.3 minutes to find the correct ratio to find themph if the speed remained constant. It is about 2.95567 and using this number multiply to 21 to get the miles per hour. the speed is about 62.069 mph. then divide the 504 miles by the mph of the car to find how long it will take to get there. It is about 8 hours 7 minutes and 20 seconds give or take, or 8.12 hours.

Answer:

The answer is below

Step-by-step explanation:

A function shows relationship between variables usually between inputs (an independent variable) and outputs (a dependent variable).

C(F) = 5/9(F - 32) shows the relationship between C and F. C(F) is the temperature in degree Celsius for any temperature in Fahrenheit. This means that the function C(F) represents the conversion of temperature from Fahrenheit to degree Celsius.

Answer:

6.61387 stones

Step-by-step explanation:

Answer:

6.6 stones

Step-by-step explanation:

1 kg= 2.2 pounds

1 stone =14 pounds ⇒ 1 pound= 1/14 stone

42 kg= 42*2.2 pounds= 92.4 pounds  

92.4 pounds = 92.4 * 1/14 stone= 6.6 stones

Answer:

В. 270°cw rotation about the origin

Step-by-step explanation:

We can rotate a total of 360 degrees in a circular pattern.

If we rotate x degrees in one direction, this rotation is equivalent to rotating (360 - x) in the other direction, because we would arrive in the same place.

So if we rotate 90 degrees in the counter clockwise direction, this is equivalent to rotating (360 - 90) = 270 degrees in the opposite direction, that is, in the clockwise direction.

So the correct option is B. -> 270°cw rotation about the origin.

Answer: Distance is 14.6

Step-by-step explanation:

[tex]d = √((x2-x1)2 + (y2-y1)2)[/tex]

[tex](x2-x1) = (7 - 3) = 4[/tex]

[tex](y2-y1) = (-6 - 8) = -14[/tex]

add it all together

[tex](4)2 + (-14)2 = 16 + 196 = 212[/tex]

Square 212

[tex]\sqrt{212} =14.5602[/tex]

Answer:

22%.

Step-by-step explanation:

7/25 = 28%

0.09 = 9%

2/5 = 40%

29% + 9% + 40% = 78%

100% - 78% = 22%

And you have your answer. Hope this helped.

Answer:

a). B = 24 yd²

b). h = 8 yd

c). S.A. = 240 yd²

Step-by-step explanation:

Area of the triangular base B = [tex]\frac{1}{2}(\text{Base of the right triangle})(\text{height of the base triangle})[/tex]

= [tex]\frac{1}{2}(8)(6)[/tex]

= 24 yd²

Height of the prism 'h' = distance between the triangular bases

                                     = 8 yd

Perimeter of the triangular base = leg 1 + leg 2 + hypotenuse

                                                      = 8 + 6 + 10 = 24 yd

Surface area = 2B + Ph

                     = (2×24) + (24×8)

                     = 48 + 192

                     = 240 square yds

Answer:

See below.

Step-by-step explanation:

6 - 23(x+5) = 4x

First, distribute.

6 - 23x - 115 = 4x

Reorder the terms.

6 - 115 - 23x = 4x

Subtract.

-109 -23x = 4x

Add 23x to both sides.

-109 = 27x

Divide by 27.

x = -109/27 (This cannot be simplified)

Answer:

The two possible solutions are x = 7, or x = -2

which agree with answer a) in the list of options

Step-by-step explanation:

Start by moving all terms to one side of the equal sign, and then factoring out the constant term:

[tex]x^2-5x-14=0[/tex]

The constant term  "-14" has ossible factors: (-1), (1) (-2), (2), (-7), (7), (-14), (14) and we look for a pair whose combining results in "-5" (the coefficient of the middle term. We find (-7) and (2) the appropriate factors, so we use then to split the middle term and then factor by grouping:

[tex]x^2-5x-14=0\\x^2-7\,x+2\,x-14=0\\x(x-7)+2(x-7)=0\\(x-7)\,(x+2) = 0[/tex]

Then if the product of these two binomial factors is zero, it means that the first binomial is zero, or the second one is zero. That is:

( x - 7 ) = 0  which means x = 7

or

( x + 2 ) = 0   which means  x = -2

So the two possible solutions are x = 7, or x = -2

Answer:

Step-by-step explanation:

[tex]x^2-5x=14\\\\x^2-5x-14=0\\\\x^2+2x-7x-14=0\\\\x(x+2)-7(x+2)=0\\\\(x+2)(x-7)=0\\\\x+2=0\quad\vee\quad x-7=0\\\\x=-2\quad\vee\quad x=7[/tex]

Answer:

Adults = 61

Students = 92

Children = 122

Step-by-step explanation:

a adults

x students

c children

a + c + x = 275

c / a = 2

5c + 7x + 12a = 1986

Simplify and solve the system.

a + 2a + x = 275

3a +x = 275

x = 275 - 3a. and c= 2a

The revenue equation can be written in terms of just one variable, a.

5(2a) + 7(275-3a) + 12a = 1986

Solve for a

a = 61

use it to find x and c.

c = 2a = 2 x 61 = 122

x = 275-a-c

x = 275 - 61-122

x = 92

Answer:

Answer:

$24

Step-by-step explanation:

Let the full price of $30 be 100%.

If the discount allowed is 20%, then the percentage of the original price that a customer will pay is:

[tex]P=100\%-20\%\\P=80\%[/tex]

80% of a marked price of $30 is:

[tex]80\%*\$30\\\$24[/tex]

A customer will pay $24.

Answer:

m = -1/3

Step-by-step explanation:

First, write the equation in slope-intercept form:

3y = 10 - x

y = 10/3 - x/3

y = 10/3 - 1/3x

Since our slope is the coefficient of the x term, our slope is -1/3.

Step-by-step explanation:

512÷8=64

108÷8=13.5

64×13.5=864

Answer:

b) 864 squares

Step-by-step explanation:

A(rectangle) = 512cm x 108cm = 55296 cm²

A(square) = 8cm x 8cm = 64 cm²

Ar/As = 55296cm²/64cm² = 864 squares

Answer: 18 animals

Step-by-step explanation:

3 out of 20 pet owners get their pet from a breeder.

To find how many animals have been bought from a breeder, you need to find 3/20 of the 122 animals.

3/20 = 0.15

122 * 0.15 = 18.3

18.3 rounds down to 18

There are 18 animals who have been bought from a breeder.
