Sonya has a collection of gold and silver coins.

Mathematics
1 answer:
faltersainse [42]3 years ago
3 0

Answer:

10.5

Step-by-step explanation:

65% of 70 is 45.5

So gold is 45.5 and silver is 54.5

so but45.5 + 54.5 = 100% but divide by 2

which is 50% but now we find 10% and 5%

10% = 7

5% = 3.5

now add 7 and 3.5 together

7+3.5 = 10.5

What is the notation for an inverse function?
solniwko [45]

Answer:

Notation. The inverse of the function f is denoted by f -1 (if your browser doesn't support superscripts, that is looks like f with an exponent of -1) and is pronounced "f inverse". Although the inverse of a function looks like you're raising the function to the -1 power, it isn't.

19x^3 + (14x + 4x^3) =
Brrunno [24]
19x³ + (14x + 4x³)=
You can assume that there is a 1 in front of the parentheses, so you can distribute the one to each term in the parentheses.
19x³ + 1(14x+4x³)=
19x³ + 14x + 4x³=
Then combine like terms to get 23x³ + 14x.
So 19x³ + 14x + 4x³= 23x³ + 14x

12345 what is the answer if you multiply 1x2x3x4x5 and do the same with subtraction, addition and devision, in that order. Then
Alexandra [31]

Well, we just need to perform the operations:

  • Multiplication: 1\cdot 2 \cdot 3 \cdot 4 \cdot 5 = 120
  • Subtraction: 1-2-3-4-5 = -13
  • Addition: 1+2+3+4+5 = 15
  • Division: 1 \div 2 \div 3 \div 4 \div 5 = \frac{1}{120}

So, if you add all the numbers together you get

120-13+15+\dfrac{1}{120} = 122 + \dfrac{1}{120}

Or, if you prefer,

\dfrac{1681}{120}
