Answer:

The 20-day old worm is \frac{5}{6} inches more longer than the 10-day old worm.

Step-by-step explanation:

Jack is growing Red wiggler worms to help make compost. He measured the lengths of two young worms. The 10- day old worm is \frac{10}{12} inch long. The 20-day old worm is 1\frac{4}{6} inches long.  

Therefore, the 10-day old worm is \frac{10}{12} i.e \frac{5}{6} inches long.

And the 20-day old worm is 1\frac{4}{6} i.e. \frac{10}{6} = \frac{5}{3} inches long

Therefore, the 20-day old worm is (\frac{5}{3} - \frac{5}{6}) = \frac{5}{6} inches more longer than the 10-day old worm. (Answer)

Answer:

Length of arc = 5 cm (Approx)

Step-by-step explanation:

Given:

Radius of circle = 20 cm

Angle = 1/4 radian

Find:

Length of arc

Computation:

Angle in degree = 1/4 radian × 180°π

Angle in degree = 1/4 × 180°  / 22/7

Angle in degree = 14.31° Approx

Length of arc = (Ф / 360)2πr

Length of arc = (14.31 /360)2(22/7)(20)

Length of arc = 4.997 cm

Length of arc = 5 cm (Approx)

let x represent one number and let y represent the other number. use the given conditions to write a system of equations. solve
kiruha [24]

9514 1404 393

Answer:

  (x, y) = (8, 2)

Step-by-step explanation:

The relevant equations are ...

  3x -y = 22

  x +2y = 12

__

We can eliminate y by adding twice the first equation to the second.

  2(3x -y) +(x +2y) = 2(22) +(12)

  7x = 56

  x = 8

Substituting into the first equation gives ...

  3(8) -y = 22

  y = 24 -22 = 2

The first number is 8; the second number is 2.

Mr.Ramirez had $600. He saved 3/5 and spent 3/8 of the remainder
Alex73 [517]

Answer:

$450

Step-by-step explanation:

Given function:

  • $600,3/5,3/8

To solve:

  • $600-3/5-3/8+3/5

Subtract the two terms:

  1. 600=\frac{30}{5}
  2. 600·\frac{3}{5}=360

Subtract the first value by 360:

  • 600-360=240

Find 3/8 of 240 and then subtract it:

  • 240·\frac{3}{8}=90

Combine the terms:

360+90=450

Therefore, Mr.Raminrez now have a total of $450..

[Please help]~granola bite contains 27 calories. Most of the calories come from c grams of carbohydrates. The rest come from oth
lutik1710 [3]

Answer: calories from other ingredients

Step-by-step explanation:

Hi, to answer this question we have to analyze the information given:

4c + 5 = 27

27 = calories contained in a granola bite

Most of the calories come from c grams of carbohydrates. The rest come from other ingredients. One gram of carbohydrate contains 4 calories.

So:

c = grams carbohydrates

4 = calories contained in 1 gram of carbohydrate

Since the sum of the product of the calories contained in 1 gram of carbohydrate (4) and the number of carbohydrates(c ); plus the calories from other ingredients is equal to the calories contained in a granola byte (27);

5 represents the calories from other ingredients

Feel free to ask for more if needed or if you did not understand something.
