2.5 kilometres is 2500 meters as 1km is 1000m

2500-2050 = 450m

as david is the one that rode 2.5 kilometres he rode further by 450 meters

She will use 10/6 or 1 2/3 cups of vegetable oil (or applesauce idk).

Hope this helps, let me know if it's wrong!

Find the distance between the points (2,0) and (-4,6)
N76 [4]

Answer:

You have to move 6 times to the left and 6 times down.

Step-by-step explanation:

If you're at (2,0), you move 2 times to the left, and then you're at (0,0).

Next move 4 times to the left. Now you're at (-4,0).

Now, move 6 times down, and now, you're at (-4,-6).

Please help!! I need step by steps thank you!!
Dmitriy789 [7]

Answer:

  1. the number is -6.4
  2. 52 students were in each bus (but one)
  3. 1 quart

Step-by-step explanation:

1.  Let the number be represented by n. Then ten times the number is 10n, and 8 more than that is 10n+8. The problem statement tells us this sum is -56:

  10n +8 = -56

  10n = -64 . . . . . . . subtract 8 from both sides

  n = -6.4 . . . . . . . . . divide both sides by 10

The number is -6.4.

__

2. First of all, you can tell there is an issue with this question because the sum of digits of 472 is 13 and the sum of those digits is 4. This tells you that dividing 472 by 9 will give a remainder of 4, not 5. One of the buses will not be filled. (This process of adding digits until you get a single digit is called "casting out nines". The remaining digit is the remainder from division by 9.)

Let b represent the number of students in each bus. Then the problem statement tells us ...

  9b + 5 = 472

  9b = 467 . . . . . . subtract 5

  b = 467/9 = 51 8/9 . . . . almost 52

52 students rode in 8 of the buses; 51 students rode in the last bus.

__

3. Let q represent the number of quarts of 6% solution. Then the total amount of Boric Acid in the mix is ...

  15%×2 + 6%×q = 12%×(2+q)

Multiplying by 100 to clear the % signs, we have ...

  15·2 +6q = 12(2+q)

  30 +6q = 24 +12q . . . . . . eliminate parentheses

  6 = 6q . . . . . . . . . . . . . . . . subtract 24+6q from both sides

  1 = q . . . . . . divide by 6

1 quart of 6% solution must be used.

In circle 0, the radius is 4, and the measure of minir arc AB is 120 degrees. Find the lenght of minor arc AB to the newrest int
Ilya [14]

Answer:

8 units

Step-by-step explanation:

Note that 120 degrees represents 1/3 of 360 degrees.  The arc described here is thus 1/3 of the circumference of this circle.

Find this circumference and then multiply that result by 1/3:

The formula for the circumference of a circle with radius r is C = 2πr.  Here,

(1/3)*(2)(π)(4 units) = 8.38 units, or (to the nearest integer) approx. 8 units.
