Thing 1
A. You can set up a proportion by dividing how much of something there is by the original. (This probably doesn't make much sense but I hope you can understand it from the answer to the problem below!)
B.First, do 168/21 to see how many more times he put flour in.
168/21= 8
Then to find out the milk in the same proportion do the number (in this case 8) times the original of the thing you wan to find out.
8x9=72
72 tablespoons of milk are needed for 168 cups of flour in this adapted recipe.

Thing 2
24/36=8y
To solve any equation, you want to have letters on one side and numbers on the other, so...
-8 from both sides...
(24/36)-8=y
24/36=0.6
y=(0.6-8)
y=-7.4

Hope this helps :)

3/4 liter of water in a bottle. if you drink 1/2 of the water, how many liters did you drink

Lapatulllka [165]

For this case we have that initially the bottle contains $\frac {3} {4}$ of liter of water.

If a person drinks $\frac {1} {2}$ of the contents of the bottle we have:

$\frac {\frac {3} {4}} {2} =\\\frac {3 * 1} {4 * 2} =\\\frac {3} {8}$

Thus, the person drinks $\frac {3} {8}$ liters of water.

Answer:

The person drinks $\frac {3} {8}$ liters of water.

How are the graphs of the functions f(x) = √16^x and g(x) =3√64^x related?

liberstina [14]

Answer:- The functions f(x) and g(x) are equivalent.

Explanation:-

Given functions:- $f(x)=\sqrt{16^x}$ and $g(x)=\sqrt[3]{64^x }$

Simplify the functions by using law of exponents

$(a^n)^m=a^{nm}$

Thus $f(x)=\sqrt{16^x}=\sqrt{(4^2)^x}=\sqrt{4^{2x}} =\sqrt{(4^x)^2}=4^x$

and $g(x)=\sqrt[3]{64^x}=\sqrt[3]{(4^3)^x}= \sqrt[3]{4^{3x}}= \sqrt[3]{(4^x)^3}=4^x$

⇒f(x)=g(x)

Therefore ,the functions f(x) and g(x) are equivalent.

The average salary for a doctorate is 39,000 less than twice that of someone with a bachelor's degree. Combined, a people (one w

tester [92]

Answer:

doctorate salary: d = $71,000

bachelor salary: b = $55,000

Step-by-step explanation:

doctorate salary: d

bachelor salary: b

relationship between b and d: d = 2b - $39,000

Unfortunately, your "1 + 126,000" could not be correct. I'm going to assume that the total of the two salaries is $126,000. If that's the case, then:

bachelor salary + (2 times bachelor salary less $39,000) = $126,000. In symbols,

b + 2b - $39,000 = $126,000

Consolidating the 'b' terms results in 3b - $39,000 = $126,000, and so:

3b = $126,000 + $39,000 = $165,000

Dividing both sides by 3 yields the bachelor salary: b = $55,000

Then the doctoral salary is 2b - $39,000 = 2($55,000) - $39,000, or $71,000.

Check: Does b + (2b - $39,000) = $126,000? Yes.

Then the doctoral salary is d = $103,000, and the bachelor salary $29,000
