An example should make this clear.
If $50 is 40% what is the value of the whole amount?
Answer:- Whole amount = 100^%
By proportion this = (100/ 40) * 50
= 2.5 * 50
= $125 (answer)
Answer:
i cant answer that
Step-by-step explanation: I cant answer because if it was for a quiz i bet the quiz is over now so there is no point in answering.
Answer:
Rider 1 does one round in 15 min, and will complete another in each consecutive multiple of 15 min
Rider 2 does one round in 18 min, and will complete another in each consecutive multiple of 18 min
Assuming that they start together, they will complete another round together in a time that is both multiples of 15min and 18 min.
Then we need to find the smallest common multiple between 15 and 18.
To smallest common multiple between two numbers, a and b, is equal to:
a*b/(greatest common factor between a and b).
Now, the greatest common factor between 15 and 18 can be found if we write those numbers as a product of prime numbers, such as:
15 = 3*5
18 = 2*3*3
The greatest common factor is 3.
Then the smallest common multiple will be:
(15*18)/3 = 90
This means that after 90 mins, they will meet again at the starting place.
Answer:
3
Step-by-step explanation:
3(1)² - 5(1) + 1
3x3 = 9
9-5+1
9-6 = 3
Answer:
Since there are already 2 angles shown, which are 48 and 90 (indicated by the square in the bigger triangle, we can set up an equation.
48 + 90 + y = 180
138 + y = 180
-138 + 138 + y = 180 - 138
y = 42°
