Which expression can be used to convert 22 Australian dollars to US dollars?Assume 1.2 Australian dollars equals 1 US dollar.

Answers

Answer 1

Answer:

Answer:

Expression used to convert 22 Australian Dollar to US Dollar is $(22)/(1.2)$

Step-by-step explanation:

Given:

22 Australian Dollars.

To Do: Expression which can be used to convert Australian dollar to Us dollar.

Let, x be the number of Australian Dollars and y be the US Dollars.

We know that 1.2 Australian Dollar equal to 1 US Dollar.

⇒ 1 Australian Dollar = $(1)/(1.2)$ US Dollar

So, x Australian Dollar = $(1)/(1.2)* x\:=\:(x)/(1.2)$ US Dollar

Thus, Expression that can be used to convert Australian Dollar into US Dollar is given by,

$y=(x)/(1.2)$

So. 22 Australian Dollar

put x = 22

$y=(22)/(1.2)=18.3$ US Dollars

Therefore, Expression used to convert 22 Australian Dollar to US Dollar is $(22)/(1.2)$

Answer 2

Answer: 1.2(22)=x
x= US Dollar amount of 22 Australian dollars.

What polynomial identity should be used to prove that 16^2=(10+6)^2? (A. Difference of Cubes; B. Difference of Squares; C. Square of Binomial; D. Sum of Cubes)

Answers

Answer:

C. Square of Binomial

Step-by-step explanation:

To prove the identity you should use square of Binomial that states the following:

$(a+b)^(2)=a^(2)+2ab+b^(2)$

Lets prove it, so first take the equation to solve:

$(10+6)^(2)$

Then square the first term:

$(10+6)^(2)=10^(2)$

Then multiply by 2 the first and second terms:

$(10+6)^(2)=10^(2)+2(10)(6)$

Finally square the second term:

$(10+6)^(2)=10^(2)+2(10)(6)+6^(2)$

Solve the values:

$(10+6)^(2)=100+2(10)(6)+6^(2)$

$(10+6)^(2)=100+120+6^(2)$

$(10+6)^(2)=100+120+36$

$(10+6)^(2)=256$

And prove the polynomial identity:

$16^(2)=256$

Calculate the radius of the sphere with the given volume.

Volume=4/81π ft^3

Answers

Answer:

(∛3)/2 ft = r

Step-by-step explanation:

Start with the formula for the volume of a sphere: V = (4/3)πr³. Solve this for r³ and then take the cube root of the result:

V = (4/3)πr³ => (3/4)V = πr³ => (------- = r³

4π

3 · 4/81π ft^3 3 · 4π ft³ 3 ft³

Here we have r³ = -------------------- = ---------------- = -------------

4π 8(4π) 8

and so the radius is r = ∛[ (3/8) ft³] = (∛3)/2 ft = r

Solve k + 4 - 2k - 24 > 0

Answers

k + 4 - 2k - 24 > 0
Subtract k from 2k
4 - k - 24 > 0
Add 24 to both sides
4 - k > 24
Subtract 4 from both sides
-k > 28
Divide -1 on both sides while flipping the inequality sign.
Final Answer: k < -28
