45 and for the top and 10/45; 3/45 for the bottom
Answer:
Step-by-step explanation:
The ration of weight of nickel, zinc, and copper in an alloy is 4:1:2
The weight of alloy can be written as
4x + x + 2x = 35 Kg
7 x = 35 Kg
X = 35 Kg/7
X = 5kg
The weight of nickel the alloy = 4 x 5 = 20 Kg
The weight of zinc in the alloy= 1 x 5 = 5kg
The weight of copper in the alloy = 2 x 5 = 10 kg
Answer:
-2/3, I'm Sorry If The Answer Is Wrong, However I'm Trying
Step-by-step explanation:
Answer:
√23 = a
Step-by-step explanation:
/ab/²= /ac/²+/bc/² (Pythagoras theorem)
12² = a² +11²
144 = a² + 121
144 - 121 = a²
23 = a²
√23 = a
ANSWER

EXPLANATION
We want to write 100,000 using exponents.
This means that, we want to write 100,000 as an index number, that is a certain number raised to a certain index or exponent.
The exponent tells us how many times that number multiplies itself to give 100,000

Since 10 multiplies itself 5 times to give 100,000, we write
