Which fraction is equal to 5/6? 8/22, 25/30, 5/15?

1 answer:

3 0

If the fraction cannot be simplified any more, you can multiply both the numerator and denominator by an number.

5/6 (multiply the top and bottom by 2) is the same as 10/12
8/22 (can be simplified by dividing top and bottom by 2) is 4/11
25/30 (simplified by dividing by 5) is 5/6
5/15 (simplified by dividing by 5) is 1/3

Hope this helps!

A boat has a rip-hole in the bottom while 20 miles away from the shore. The water comes in at a rate of 1.5 tons every minute, a

Montano1993 [528]

Answer:

t = 70 tons/1.5 tons/min = 46.7 min = 2800 sec before boat sinks

S = V * t

V = S / t = 20 mi * 5280 ft/mi / 2800 sec = 37.7 ft/sec

Since 88 ft/sec = 60 mph

the speed is 60 * 37.7 / 88 = 25.7 mph

You roll a pair of dice. What is the approximate probability that the dice shows a sum of 10 or the same number on each die?

kirza4 [7]

probability that the dices show a sum of 10:
4,6 - 5,5 - 5,5 - 6,4 >> four outcomes


probability that the same number appears on each dice:
1,1
2,2
3,3
4,4
5,5
6,6
>>>>>>>> 6 outcomes

and all outcomes are 36 results

so our probability will be: (4+6) / 36 = 10 / 36 = 5/18 =0.2778 = 27.78%

hope that helps

Find an equation for the line that passes through the points (6, -1) and (-6, 2).

kirill115 [55]

Answer:

$D : y = \frac{-1}{4}x + \frac{1}{2}$

Step-by-step explanation:

let D be the line that passes through the points (6, -1) and (-6, 2)

Then D has an equation of the form D: y = ax + b

Now we need to find a and b in order to be able to write the equation of the line D:

$a = \frac{-1-2}{6-(-6)}= \frac{-3}{12}= \frac{-1}{4}$

Since the point (6 , -1) lies on the line D then :

-1 = (-1/4) × (6) + b

then

-1 = (-6/4) + b

then

b = -1 - (-6/4) = -1 + 6/4 = -4/6 + 6/4 = (-4+6)/4 = 2/4 = 1/2

then

b = 1/2

Conclusion:

Since a = -1/4 and b = 1/2 then

$D : y = \frac{-1}{4}x + \frac{1}{2}$

Please help !! Will mark brainliest answer

Norma-Jean [14]

Answer:

x = 12

Step-by-step explanation:

18:24 (comparing the same sides for the similar shapes; 18 and 24) when simplified down is equal to 3:4.

Using this 3:4 scale factor we can find the missing side x.

Solving for x :

$\frac{3}{4}$ × 16 = 12

x = 12

OR: Set up a proportion:

$\frac{24}{16}$ × $\frac{18}{x}$

cross-multiply

16 × 18 = 288

24 × x = 24x

288 = 24x

x = 12
