Answer:
Step-by-step explanation:
This is a proportion problem. I think you just lost a zero.
12/100 = 9/x Cross multiply
12x = 100*9 Combine the right.
12x = 900 Divide by 12
12x/12 = 900/12
x = 75 grams
So if you put 75 grams of tasty Oats in a bowl and covered it with milk the cereal would give you 9 grams of Protein.
2.
1 gram of Tasty Oats cereal contains 12/100 = 0.12 grams of protein.
1 gram of Cornbits contains 5/45 = 0.11 grams of protein.
By the narrowest of margins the Tasty Oats has more protein in it.
Step-by-step explanation:
First, replace f(x) with y . ...
Replace every x with a y and replace every y with an x .
Solve the equation from Step 2 for y . ...
Replace y with f−1(x) f − 1 ( x ) . ...
Verify your work by checking that (f∘f−1)(x)=x ( f ∘ f − 1 ) ( x ) = x and (f−1∘f)(x)=x ( f − 1 ∘ f ) ( x ) = x are both true.
On a right triangle, to find one missing side you can use this equation
a^2 + b^2 = c^2
a and b are the sides next to the right angle, and c is the hypotenuse (side not connected to right angle).
You first need to find the length of the dotted line before finding x. This is because to be able to use the above formula, you have to know the length of two out of three of the sides.
To solve the length of the dotted line, note that it also makes a triangle with the 5 unit line and the 5 √5 unit line. You can plug these numbers into the formula.
(5)^2+b^2=(5 √5)^2
25+b^2=125
b^2=100
b=10
Now that you know the length of the dotted line is 10 units, you can now solve for x
(20)^2+(10)^2=x^2
400+100=x^2
500=x^2
x= √500, which equals 22.361
6 × (13 - 6) = 42, not 7, but 7² is 49 and 42² is 1,764.
I hope this helps!
