In the 2004 Summer Olympics, Adam van Koeverden of Oakville, Ontario, won two medals. He won the gold medal in the men’s 500 m kayak race, with a time of 1 min 37.9 s. He also won the bronze medal in the 1000 m race, with a time of 3 min 28.2 s. In which race did he row with greater speed?

Answers

Answer: 500 meters

Step-by-step explanation:

Since he won the gold medal in the men’s 500 m kayak race, with a time of 1 min 37.9 s, the speed will be:

= Distance/Time

= 500m/1 min 37.9s

= 500m/97.9s

= 5.11m/s

Since he also won the bronze medal in the 1000 m race, with a time of 3 min 28.2s, the speed will be:

= Distance/Time

= 1000/3 min 28.2s

= 1000m/208.2s

= 4.80m/s

Therefore, he rowed with greater speed in the 500 meters.

Note that 60seconds = 1 minute

Sara makes some Blue paint. She mixes yellow, red and brown in the ratio 4: 6: 9. He uses 340 ml of the yellow paint. How much Blue paint does he make?

Answers

Answer:

1615

Step-by-step explanation:

the equation that represents the amount of yellow paint used =

(ratio of yellow paint / sum of ratios) x p = 340

p = blue paint

4 / 19 x p = 340

p = 1615

A business owner wants to have the front window of her store painted and is considering two
artists for the job. Tiana has quoted a flat rate of $292 for the job. Denise's quote is $39 per
hour, plus $19 to cover the cost of materials. Depending on how long it takes Denise to paint
the window, these two could end up charging the same amount. How long would Denise have
to take? How much would it cost?

Answers

denise would have to take seven hours to charge the same amount of money as tiana. furthermore, it would cost the same amount as that is what the prompt is asking for.

to get the answer:
i subtracted $19 from $292 to eliminate the
fee element because if you were to divide
$292 by $39 without the step, the hours would be incorrect and the price would be greater.

after subtracting i got $273

from there i divided $273 by $39 and got 7 (the amount of hours it would take)

what is the missing exponent?

17 / 17^4 = 17^8​

Answers

Answer:

The missing exponent is 12.

Step-by-step explanation:

Whenever you divide same-base exponents, you keep the base numbers the same and subtract the exponents.

The only number subtracted by 4 that would give you 8 is 12.

Or, if the numbers are larger, it is must easier to add the exponent in the answer to the number in the equation.

For example,

[tex]17^4+17^8=17^1^2[/tex]

Therefore, the missing exponent is 12.

Because:  [tex]17^1^2/17^4=17^8[/tex]

Step-by-step explanation:

We will use the standard form of a circle to solve for the radius and then fill it back in. h is 0, k is 0, x is 3, and y is 6:

[tex](3-0)^2+(6-0)^2=r^2[/tex] and

[tex]3^2+6^2=r^2[/tex] and

To answer you use the Pythagorean theorem, a^2+b^2=c^2

10. C= 5
11. B= 2 V55 (2 square root of 55)
12. C= 2 V5
13. A= V5.39

Explanation:

10. a^2+b^2=c^2
3^2+4^2=c^2
9+16=c^2 (add 9 and 16)
25=c^2
V25= Vc^2 (take the square root of both sides to get):
5=c

11. 6^2+b^2=16^2
36+b^2=256 (256-36)
b^2=220 (square root, 220 cannot be simplified so you factor it and get):
b= 2 V55

12. 4^2+2^2=c^2
16+4=c^2
20=c^2 ( square root it then factor)
2 V5 = c

13. a^2+3.5^2=4.2^2
a^2+12.25=17.64 (subtract 17.64 and 12.25)
a^2=5.39 ( square root/ cannot be simplified so the square root of 5.39 is your answer)


I hope this helped you understand! I hope you have a good day!

Answer:

Use Pythagorean to find the missing side lengths.It assumed a and b are legs and c is the hypotenuse.All numbers are rounded to the nearest tenth.

#10

[tex]c = \sqrt{3^2+4^2} = \sqrt{25} = 5[/tex]

#11

[tex]b = \sqrt{16^2-6^2} = \sqrt{220} = 14.8[/tex]

#12

[tex]c = \sqrt{4^2+2^2} = \sqrt{20} = 4.5[/tex]

#13

[tex]a = \sqrt{4.2^2-3.5^2} = \sqrt{5.39} = 2.3[/tex]
