Erin buys 3 packs of potatoes costing £3 each, 3 packs of carrots for £2 per pack, and 4 turnips costing 60p each.
If she pays with a £20 note, how much change would she get?

Answers

Answer:

£2.6

Step-by-step explanation:

Given data

3 packs of potatoes costing £3 each= 3*3= £9

3 packs of carrots for £2 per pack= 3*2= £6

4 turnips costing 60p each= 4* 0.60= £2.4

Hence the total cost = 9+6+2.4= £17.4

Hence the change will be 20-17.4

= £2.6

Answers

Answer:

  1

Step-by-step explanation:

The right triangle is isosceles, so x = 45° and tan(x) = 1.

__

You can determine tan(x) either from your knowledge of trig function values, or from the fact that the two legs of the triangle are of equal length. The tangent is the ratio of the opposite leg to the adjacent one. When those legs are the same, the ratio is 1.

Common difference, ratio, or neither?

Answers

9514 1404 393

Answer:

Arithmeticcommon difference = 7

Step-by-step explanation:

First differences are ...

  -38 -(-45) = 7

  -31 -(-38) = 7

  -24 -(-31) = 7

The first differences are constant, so this is an arithmetic sequence with a common difference of 7.

Please help!! 1/6+1/3+1/6

Answers

Answer:

2/3

Step-by-step explanation:

1/6+1/6= 2/6, both divided by 2 gives you 1/3

1/3+1/3= 2/3

Good luck luv

Hope this helps

Answer:

2/3

Step-by-step explanation:

To add fractions with different denominators, change the denominator to the least common multiple of the denominators.

The denominators here are 6, 3, and 6. The least common multiple of these three numbers is 6. Now, convert each of the fractions into fractions with a denominator of 6, specifically only 1/3.

1/6+2/6+1/6

Now add up the numerators,

1/6+2/6+1/6 = 4/6

Simplify.

4/6 = 2/3
