Based on the information provided by the table, it can be inferred that Running the half marathon took more than double the time than running the 5K. (option C)

The graphs shown relate the time and age of athletes who ran 5k and half marathon.

The first graph shows the relationship in 5k, in which all the athletes, regardless of their age, managed to complete the test between 20 and 30 minutes.

The second graph shows the relationship in the half marathon, in which the younger runners completed the test in less time (80 minutes) than the older athletes (140 minutes).

According to this information, it can be inferred that the athletes took more than twice the time used in the 5k race to complete the half marathon (option C)

Step-by-step explanation:

square is 10x10 = 100

circle is A=πr2=π·5²≈78.54

100-78.54 = 21.46 = 21.5

Answer:

21.5 sq cm

Step-by-step explanation:

Area of Square:

A= LXW= 10x10= 100 sq cm

Area of Circle=

A=πr²

Radius= D/2= 10/2= 5 cm

A=3.14(5²)

Step-by-step explanation:

Given that:

Greatest whole number that round to 400,000 when rounding to the nearest hundred thousand :

To obtain the greatest whole number which rounds to 400,000, the whole number is greater Tha 400,000 and its 10 thousand digit in the number or value to be rounded must be lesser than 5.

The value would be 449,999 ; here z the 10 thousand value which is 4 is rounded to zero since it is not up to 5 and the subsequent digits also rounded to 0 to give ;

400,000 (nearest hundred thousand).

The proportion is solved and the number of roses is R = 21

The proportion formula is used to depict if two ratios or fractions are equal. The proportion formula can be given as a: b::c : d = a/b = c/d where a and d are the extreme terms and b and c are the mean terms.

The proportional equation is given as y ∝ x

And , y = kx where k is the proportionality constant

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Given data ,

Let the proportion be represented as A

Now , the value of A is

If the ratio of daisies to roses is 2:7, this means that for every 2 daisies, there are 7 roses.

If there are 6 daisies, we can use this ratio to find out how many roses there are.

2 daisies = 7 roses

On simplifying the proportion , we get

1 daisy = 7/2 roses (dividing both sides by 2)

So, if there are 6 daisies:

6 daisies = (7/2) x 6 = 21 roses

Hence , there are 21 roses

Answer:

the area of a triangle is 9 because 4.24 times 4.24 equals 17.9776 estimated is 18 divided by 2 is 9 times 4 is 36. Now we divide 36 by 2 so we know what the area of the two trapezoids so we know the top and the bottom which is 18. The area of the square in between the triangles is 4.24 times 6 which is 25.22 estimated is 26. Now we add 26 with 18 which is 34. Now we have to find the area of the rectangle to do this we need to multiply 7.24 and 2 we need to do this so we know the length of the rectangle which is 14.48 estimated is 14. Now that we know the length we multiply it with the height which is 6, 14 times 6 equals  84.

84 is the rectangles area and the area for the trapezoids is 36.

84 plus 18 plus 18 equals 120 squared

Answer:

Step-by-step explanation:

16cos(30)-20sin(60) -8sin(90)

look at the pattern of the numerators Millie, you can remember all of the sin and cos  functions at the special angles now. :)

sin(0) = 0 / 2

sin(30) = 1 / 2

sin(45) = [tex]\sqrt{2}[/tex] / 2

sin(60) = [tex]\sqrt{3}[/tex] / 2

sin(90) = [tex]\sqrt{4}[/tex] / 2   aka  1

now the numerators just count up from 90°

cos(90) = 0 / 2

cos(60) = 1 / 2

cos(45) = [tex]\sqrt{2}[/tex] / 2

cos(30) = [tex]\sqrt{3}[/tex] / 2

cos(0) =  [tex]\sqrt{4}[/tex] / 2   aka  1

see the pattern.. it's pretty easy to memorize, knowing that :)

now let's use the above to plug into the given equation

16* [tex]\sqrt{3}[/tex] / 2 - 20* [tex]\sqrt{3}[/tex] / 2- 8*[tex]\sqrt{4}[/tex] / 2

8* [tex]\sqrt{3}[/tex] - 10 [tex]\sqrt{3}[/tex]  -8

-2*[tex]\sqrt{3}[/tex]  - 8

this isn't quite the same answer as you got before.. I feel like it's right

Answer:

.2 degrees

Step-by-step explanation:

180-170 is 10

10/50 is .2

The size of the other angle will be 0.2 degrees.

A polynomial in mathematics is an expression made up of coefficients and indeterminates and involves only the operations of multiplication, addition, subtraction, and non-negative integer exponentiation of variables.

The angle is defined as the span between two intersecting lines or surfaces at or close to the point where they meet.

It is given that a polygon has 50 sides but one of its angles is 170 degrees.

The remaining angle will be calculated as:-

180-170 = 10

The size of the other angle is calculated below:-

Angle = 10/50

Divide the value 10 by 50 to get the angle.

Angle = 0.2

Therefore, the size of the other angle will be 0.2 degrees.

Answer:

  x = 33

Step-by-step explanation:

The angles are complementary.

  x° = 90° -57°

  x = 33

Given:

Length of the rectangle = [tex]x+4[/tex]

Width of the rectangle = [tex]x[/tex]

The perimeter of the rectangle is less than 140.

To find:

The inequality for the given situation and solve it.

Solution:

We have,

[tex]l=x+4[/tex]

[tex]w=x[/tex]

We know that, the perimeter of a rectangle is

[tex]P=2(l+w)[/tex]

[tex]P=2(x+4+x)[/tex]

[tex]P=2(2x+4)[/tex]

[tex]P=4x+8[/tex]

It is given that the perimeter of the rectangle is less than 140.

[tex]P<140[/tex]

[tex]4x+8<140[/tex]

[tex]4x<140-8[/tex]

[tex]4x<132[/tex]

Divide both sides by 4.

[tex]x<\dfrac{132}{4}[/tex]

[tex]x<33[/tex]

Therefore, the correct option is A because the sign of inequality is < and the solution of inequality is [tex]x<33[/tex].
