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

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?
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
Determine if the sequence is arithmetic, geometric, or neither. For arithmetic and geometric sequences, identify the common difference or common ratio. For neither, enter n/a. {-45, -38, -31, -24, ...}
Arithmetic, Geometric, or Neither?
Common difference, ratio, or neither?
9514 1404 393
Answer:
Arithmeticcommon difference = 7Step-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.

13.) An electrician has a piece of wire that is 3 feet long (36 inches). She needs a piece that is exactly 31.05 inches to fit perfectly in the outlet. How much wire will she have left over? *
O she needs to buy more baseboard, she doesn't have enough
O 4.95 inches
O 28.05 inches
O5.05 inches
Answer: 4.95 inches
Subtract: 36 - 31.05 = 4.95
Step-by-step explanation:
Whoever created this question hasn't done much real electrical work!
An outlet (also known as a receptacle) usually requires about 4 to 6 inches of wire within the junction box to make the connections, depending on what else may be connected in the box. We don't have to measure to 0.05 of an inch. The insulation may have to be stripped precisely to 3/8, 1/2 or 5/8 inch for connections.
The electrician used 3 feet of cable between junction boxes, and had 8 ¹/₂ inches pulled through the junction box. She needed 4 inches to connect the receptacle. How much the excess did she have to cut off?
Math questions should be realistic.

Please help me ASAP please
9514 1404 393
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.
