Answer:
£17.20
Step-by-step explanation:
A clothes shop has some special offers. ?
The normal price of a T-shirt is £7.40 The normal price of a jumper is £9.80.
T-shirts are buy one get one free Jumpers are 3 for 2.
How much does it cost to get 5 jumpers and 2 T-shirts using this offer as appropriate?
The cost of 2 T-shirts since it is a buy 1 get 1 free => £7.40
The cost of 5 jumpers =
You buy 3 Jumpers ,you get 2 jumpers free => £9.80
The total cost = £7.40 + £9.80
= £17.20
Answer:
9.80 m
Step-by-step explanation:
The mnemonic SOH CAH TOA is intended to remind you of the relationship between sides of a right triangle and its angles.
__
<h3>setup</h3>
The geometry of this problem can be modeled by a right triangle, so these relations apply. We are given an angle and adjacent side, and asked for the opposite side, so the relation of interest is ...
Tan = Opposite/Adjacent
Using the given values, we have ...
tan(24°) = AC/AB = (tree height)/(distance from tree)
tan(24°) = AC/(22 m)
<h3>solution</h3>
Multiplying by 22 m gives ...
tree height = AC = (22 m)·tan(24°) ≈ 9.79503 m
The height of the tree is about 9.80 meters.
Answer:
It is not.
Step-by-step explanation:
Using the Pythagorean Theorem, a squared + b squared = c squared, we get 25 + 64 = 100, and this is not true.
Answer:
No
Step-by-step explanation:
A little trick to easily see if things are divisible by 3 is to add the 2 numbers together.
For example with 71 if you add 7+1 you get 8. 8 is not divisible by 3.
However if you were looking at 81 you add 8+1 to get 9. 3×3=9 so 81 is divisible by 3.
By putting that into a calculator you can see that 81/3=27 and 71/3=23.6666...
Hope that helped!
