Answer:
5 ft
Step-by-step explanation:
When we draw out our triangle, we should see that we have a right triangle and we need to solve for a leg:
Pythagorean Theorem: a² + b² = c²
12² + b² = 13²
144 + b² = 169
b² = 25
b = 5
Answer:
£15.7
Step-by-step explanation:
32 cans x 50P = 1600p
1600p to Pounds = £26.66 (1600 divided by 60)
Remaining cans = 18 (50 - 32)
18 cans x 20p = 360p
360p to Pounds = £6 (360 divided by 60)
£26.66 + £6 = £32.66
£32.66 (Profit) - £17 (Cost of cans) = £15.66
15.66 to 3SF = 15.7
To solve this problem you have to convert the percentage to a decimal which would
be .40.
40% =40/100=.40
After doing so all you need to do is divide the amount needed by the percentage which gives you the amount she has saved.
225/.40= $90
Lauren has $90 saved
