Answer:

Do not have enough time to answer all of them, but I hope the one I answered will help You, and You can solve 11 too

Step-by-step explanation:

10. Now Jane is x years old. 12 years ago she was (x-12) years old. So Anne at that time was (x-12)/5 years old. After 3 years Jane will be (x+3) years old and Ann (x+3)/2. 12 years ago Anne was (x-12)/5 years old and after 3 years she will be (x+3)/2 years old. If we subtract ages` (x+3)/2-(x-12)/5=15(years passed)

solving this` x=37. Now Jane is 37, and Anne 17

8. In given triangle all sides are equal thus (3x-y)=(x+5)=(y+3)

Representing x with y we have x=y-2. Replace x with y-2 =>

3y-6-y=y+3 => Simplifying y=9, hence each side is y+3=12, x is 7

Answer to 8. 12

Fiesta28 [93]

Answer: option 4 is the correct answer.

Step-by-step explanation:

The graphs shown in the photo are plots of distance versus time.

Distance travelled = speed × time

On a run, Natasha ran for 1 1/4 hours at a speed of 6 miles per hour. The distance that she covered would be

6 × 1.25 = 7.5 miles

She then rested for 1/4 hour. This means that her speed is 0 and the distance covered is also 0 miles.

She then ran for another hour at a speed of 5 miles per hour. Distance covered would be

5 × 1 = 5 miles

Total time spent would be

1.25 + 0.25 + 1 = 2.5 hours

Total distance covered would be

7.5 + 5 = 12.5 miles

Therefore, the 4th graph best represents the distance she traveled

5 ft is ____ % of 37 1 2 ft; 37 1 2 ft is ____ % of 5 ft
hichkok12 [17]

Answer:

The answer is:

5 ft is <u>13.33</u>% of 37 1/2 ft; 37 1/2 ft is <u>750</u>% of 5 ft.

Step-by-step explanation:

Given:

5 ft is ____ % of 37 1 2 ft.

Now, to find the __ :

Let __ be x.

So, 5 ft is x\% of 37 1/2

5=x\% of 37\frac{1}{2}

⇒ 5=\frac{x}{100} \times \frac{75}{2}

⇒ 5=\frac{75x}{200}

Multiplying both sides by 200 we get:

⇒ 1000=75x

Dividing both sides by 75 we get:

⇒ 13.33=x

⇒ x=13.33\%.

Now, 37 1/2 ft is x% of 5 ft.

\frac{75}{2} =x\%\ of\ 5

\frac{75}{2}=\frac{x}{100}\times 5

\frac{75}{2} =\frac{5x}{100}

Multiplying both sides by 100 we get:

\frac{7500}{2} =5x

Dividing both sides by 5 we get:

750=x

x=750\%

Therefore, the answer is 5 ft is <u>13.33</u>% of 37 1/2 ft; 37 1/2 ft is <u>750</u>% of 5 ft.
