The track star runs 100m at a rate of 10.4m/s. How long did it take to run 100m?
0.1 m/s
9.65
1040m/s
0.1s

Answers

Answer 1

Answer:

Time, t = 9.615 secs.

Explanation:

Speed can be defined as distance covered per unit time. Speed is a scalar quantity and as such it has magnitude but no direction.

Mathematically, speed is given by the equation;

[tex]Speed = \frac{distance}{time}[/tex] ....equation 1

[tex]Time = \frac{distance}{speed}[/tex] .....equation 2

Given the following data;

Distance = 100m

Speed = 10.4m/s

Substituting into equation 2;

[tex]Time = \frac{100}{10.4}[/tex]

Time, t = 9.615 secs.

Anagha's mother bought an equal number of ladoos and pedas. She put 13 of the ladoos and 15 of the pedas into a packet and gave it to Anagha to distribute at school. If there were a total of 80 sweets in the packet, how many ladoos did Anagha's mother buy?

Answers

Answer:

150

Step-by-step explanation:

Anagha's mother bought an equal number of ladoos and pedas. Let there are x number of ladoos and pedas.

She puts x/3 of the ladoos and x/5 of the pedas into a packet and gave it to Anagha to distribute at school.

Total no of sweets in the packet = 80

[tex]\dfrac{x}{3}+\dfrac{x}{5}=80\\\\\dfrac{5x+3x}{15}=80\\\\\dfrac{8x}{15}=80\\\\x=\dfrac{80\times 15}{8}\\\\x=150[/tex]

So, there are 150 ladoos brought by Anagha's mother.

The leg of a right triangle is 3 units and the hypotenuse is 4 units. What is the length, in units, of the other leg of the triangle?

Square root of 5
Square root of 7
5
7

Answers

Answer:

7

Step-by-step explanation:

let the other leg be x

Then using Pythagoras' identity

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is

x² + 3² = 4²

x² + 9 = 16 ( subtract 9 from both sides )

x² = 7 ( take the square root of both sides )

x = 7

Answer:

7

Step-by-step explanation:

let the other leg be x

Then using Pythagoras' identity

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is

x² + 3² = 4²

x² + 9 = 16 ( subtract 9 from both sides )

x² = 7 ( take the square root of both sides )

x = 7

Solve for the value of q.

Answers

Answer:

If you mean that 134 degrees = (9q - 8), the answer is: q = 15.78 degrees

142/9 = q

15.78 = q

q = 15.78 degrees

answer: 35°

explanation: the sum of all the interior angles in a triangle will always equal 180°. in this triangle we have a right angle which is equal to 90°, a 55° angle, and x°. To find out x you would do 90 + 55 = 145. once you get that you would then do 180 - 145 = 35. So, X = 35°

Then when you divide the denominators you'll get 15.

60 divided by 15 is 4.

10/3 x 6/5 = 4

Step-by-step explanation:

You multiply the numerators together, same with the denominator. You get 60/15. You divide those numbers so you get 4 as your answer. Hope this helps!

Step-by-step explanation:

Is that the right answer ?

Answers

Answer:

Yes, that is correct

Step-by-step explanation:

The formula for the slope can be referred to as "rise over run", a fraction where the rise (change in the y direction) is divided by the run (change in the x direction).

We can get the rise and run by choosing two points on the slope and looking for the change in the x and y direction. In this case, let us use the points (-4,0) and (0,-5). The change in the y direction is from 0 to -5, thus the rise will be -5. Likewise, the change change in the x direction is from -4 to 0 and the run will be 4.

Going back to "rise over run", we divide the rise by the run, giving us -5/4

24.7.
24.8
O 288
0 612

Answers

Answer:

24.7 inches

Step-by-step explanation:

Length = 18 inches

Width = 12 inches

Height = 12 inches

Length of the longest diagonal,d = length^2 + width^2 + height^2

d^2 = 18^2 + 12^2 + 12^2

d^2 = 324 + 144 + 144

d^2 = 612

d = √612

= 24.7 of inches

Length of the longest diagonal in the box = 24.7 inches

When playing a track on the outer edge, a CD rotates 300 times per
minute. Through how many degrees does it rotate in one second?

Answers

Answer:

I think it's 1800 Degress

Step-by-step explanation:

If the CD rotates 300 times per minute, we know that equals 300 rotations/60 seconds

That ends up being 5 rotations per second.

Since we know that a full rotation is 360 degrees, then it should equal 1800 degrees.
