A sprinter travels a distance of 100 m in a time of 8.96 seconds.
What is the sprinter's average speed rounded to 4 sf

Answers

Answer 1

The average speed is 40.176 Km/h.

What is Average speed?

The average speed is the total distance traveled by the object in a particular time interval.

Given:

distance = 100m

time= 8.96 seconds

So,

average speed = distance/time taken

= 100/8.96

= 11.16 m/s

and in Km/h

= 11.16* 18/5

= 40.176 Km/h

Hence, the average speed is 40.176 Km/h.

2.A baker has 400kg of flour on the first day of the month and uses no flour that day. How much will he have at closing time on the 17th day of the month, if he uses 24 kg each day after that?

Answers

1. At the end of the 5th week he would have saved a total of $700

2. The amount of flour he would have at the closing time on 17th of the month will be 16kg

1.

Azad amount = $500

He wants to go on a holiday but he lacks sufficient money. This means the $500 in his possession is not enough.

He decided to save $40 dollars per week for a number of weeks to make up the deposits.

let

w = number of weeks

Therefore, his saving for any number of weeks will be

40w

The amount he would have saved for 5 weeks will be

40×5=$200

The total amount in his possession at the end of the fifth week will be  200 + 500 = $700

2.

The baker has 400 kg of flour. The first day of the month he didn't use any flour. This means on the first day of that month the flour was still 400 kg. The amount he has on the 17th day of the month can be calculated below.

The 17th day simply implies he used the flour for 16 days, the first day of the month he didn't use anything. He uses 24 kg for each day. Therefore the amount he uses for 16 days will be

16×24=384 kg

The amount he has at the closing time of 17 days of the month will be

400kg - 384kg = 16kg

Find the direct variation.

if y=28 when x= 168, find y when x =108.

Answers

Answer:

18

Step-by-step explanation:

168 : 28 : : 108 : y

168 / 28 = 108 / y

6 = 108 / y

6 * y = 108

y = 108 / 6

y = 18

Answer:

y = 18

Step-by-step explanation:

Given y varies directly as x then the equation relating them is

y = kx ← k is the constant of variation

To find k use the condition y = 28 when x = 168

28 = 168k ( divide both sides by 168 )

[tex]\frac{28}{168}[/tex] = k , that is

k = [tex]\frac{1}{6}[/tex]

y = [tex]\frac{1}{6}[/tex] x ← equation of variation

When x = 108 , then

y = [tex]\frac{1}{6}[/tex] × 108 = 18

What’s the rise over run pleas???

Answers

9514 1404 393

Answer:

  -1/5

Step-by-step explanation:

To find the ratio of rise to run on a graph, it is convenient to start by looking for points where the graph crosses the intersection of grid lines. This lets you read the exact coordinates of the points, without any guessing.

In the attachment, the grid crossings we chose are circled.

The "rise" is the vertical distance between the points. If the right point is lower, the "rise" is negative.

The "run" is the horizontal distance between the points.

The reason for choosing grid crossings is that it then becomes fairly easy to count the grid lines between the points, vertically and horizontally.

On this graph, the "rise" is -1 for a "run" of 5. Then the slope, or ratio of rise to run, is ...

  m = rise/run = -1/5 . . . . . . slope of the line

On a coordinate plane, 2 straight lines are shown. The first solid line has a positive slope and goes through (0, negative 2) and (2, 0). Everything to the left of the line is shaded. The second dashed line has a negative slope and goes through (0, 2) and (4, 0). Everything below and to the left of the line is shaded.
Which system of linear inequalities is represented by the graph?

y > x – 2 and x – 2y < 4

Answer:

Step-by-step explanation:

Pythagorean theorem is [tex]a^{2} +b^{2} =c^{2}[/tex].

Which in this case:

'c' is hypotenuse. (hypotenuse = 20)

'a' and 'b' are the other sides. (a = x, b = 8)

[tex]a^{2} +b^{2}= c^{2}[/tex] [tex]x^{2} +8^{2} =20^{2}[/tex] [tex]x^{2} + 64 = 400[/tex] [tex]x^{2} = 336[/tex]

Now we should just take square root from the both sides.

and the answer will be [tex]\sqrt{336}[/tex] or [tex]-\sqrt{336}[/tex], but a side of a triangle can not be a negative number! so the answer will be [tex]\sqrt{336}[/tex].

As you see [tex]\sqrt{336}[/tex] is not the simplest radical.

We can write [tex]\sqrt{336}[/tex] as [tex]\sqrt{16 * 21}[/tex].

And from the laws of radical we can write [tex]\sqrt{16*21}[/tex] as [tex]\sqrt{16} * \sqrt{21}[/tex].

[tex]\sqrt{16} * \sqrt{21} = \sqrt{16}\sqrt{21} = 4\sqrt{21}[/tex]

If a²+b²=8ab, determine (a+b) in terms of a and b​

Answers

[The question's not wholly right! Since, (a+b) has a and b in it, it already is in terms of a and b. Here, we'll be representing (a+b) in terms of ab]

Answer:

[tex]\mathsf{\sqrt{10ab} }[/tex]

Step-by-step explanation:

We have the rules of indices, one of which is:

[tex]\boxed{\large{\mathfrak{(a+b)^2=a^2+b^2+2ab}}}[/tex]

Indices are the powers, the numbers written as superscript in front of a variable or the numbers that come along with "^". It shows how many times a number is to be multiplied by itself.

In the question, we're provided with one equation, i. e.,

a² + b² = 8ab . . . . . . . . (¡)

And, were asked to find out the value of (a+b) in terms of ab.

The above rule has variables that fit in the question efficiently!

So, instead of solving for (a+b), we'll be solving for (a+b)²,  then go for (a + b):

=> (a + b)² = (a² + b²) + 2ab

from eqn. (¡):

=> (a + b)² = 8ab + 2ab

=> (a + b)² = 10ab

taking under root on both the sides:

=> (a + b) = [tex]\mathsf{\sqrt{10ab} }[/tex]

That's the answer,  [tex]\mathsf{\sqrt{10ab} }[/tex]!
