Alexander has nickels, dimes, and quarters in the ratio of 2:1:8, if 40 of Alexander's coins are quarters, how many nickels and
ch4aika [34]

Answer:

He has 10 nickels and 5 dimes

Step-by-step explanation:

We can take advantage of the ratio by dividing 40 by 8, giving us that every 1 in the ratio = 5. So we can multiply 2 x 5 = 10 and 1 x 5 = 5.

Hope this Helps!

Which of these choices show a pair of equivalent expressions? Check all that apply.
AleksAgata [21]
The main rule we use in this exercise is 

( \sqrt{a} ) ^{m} =( a^{ \frac{1}{2}} )^{m} = a^{ \frac{1}{2}*m}=a^{ \frac{m}{2}}

and the more general case: 

(  \sqrt[n]{a}  ) ^{m} =( a^{ \frac{1}{n}} )^{m} = a^{ \frac{1}{n}*m}=a^{ \frac{m}{n}}
Using these rules, we make all the indices, or exponents, look like a^{ \frac{m}{n}}, and compare them to each other.

A. ( \sqrt{8} )^{9} =  (  8^{ \frac{1}{2}}   )^{9} = 8^{ \frac{1}{2}*9}= 8^{ \frac{9}{2}}

B. ( \sqrt{4} ) ^{5} =( 4^{ \frac{1}{2}} )^{5} = 4^{ \frac{1}{2}*5}=4^{ \frac{5}{2}}

C. (  \sqrt[3]{125} ) ^{7} =( 125^{ \frac{1}{3}} )^{7} = 125^{  \frac{1}{3}*7}= 125^{ \frac{7}{3}}

D. ( \sqrt{12} ) ^{7} =( 12^{ \frac{1}{2}} )^{7} = 12^{ \frac{1}{2}*7}=12^{ \frac{7}{2}}

Find the value of X in the triangle shown below.
Travka [436]

Answer:

50

Step-by-step explanation:

The sum of a triangle's angles are 180 so since you know one angle is 80, you would put 2x + 80 = 180, which would be 2x = 100, which simplifies to x = 50
