Simply put you multiply 30 by 8.
30*8 = 240
So in total he bought 240 hot dogs.
Answer:
y=100
Step-by-step explanation:
You can solve this by comparing the ratio.
The first set is 10:20 or 1:2 when simplified.
This can then be applied to the second set. If x=50, then 50 times 2 will give you the answer of 100.
Hey there!
Solve using pythagoras theorem (it's given that is triangle is right angled. Pythagoras theorem only works in the case of right triangles) ⇨ Hypotenuse² = Base² + Altitude ²
Here,
Base = 9 mm
Hypotenuse = 15 mm
Altitude = b
Hypotenuse² = Base² + Altitude ²
15² = 9² + b²
225 = 81 + b²
225 - 81 = b²
144 = b²
√144 = b
<u>1</u><u>2</u><u> </u><u>mm </u>= b
Hope it helps ya!
