Verdich [7]

The answer would be .4% of the 150 would be boys choosing this. Here's my work.

First, I found out what 3/5 of 150 would be (divided by 5, then multiplied by 3)
Then I subtracted that number from 150 and ended up with 60 (since 3/5 of 150 is 90)
And finally, I took 60 and divided that by 150 to get .4% of the 150 students who said their fav flavor of ice cream was chocolate was boys.

Richland's Real GDP per person is #10b and poorland's Real GDP per person is #5b. However, Richland's Real GDP per person is gro

masya89 [10]

Answer:

after 5 years, rich : poor = 11.0 : 6.7
after 10 years, 12.2 : 9.0
35.3 years

Step-by-step explanation:

It is convenient to let a graphing calculator show the answers to these questions.

The exponential equation modelling the growth will be of the form ...

f(x) = (initial value) × (1 +growth rate)^x

Richland's GDP/person can be modeled by r(x) = 10·1.01^x

Poorland's GCP/person can be modeled by p(x) = 5·1.03^x

The attached graph shows values for x=5, 10 and r(x)=p(x).

It will take about 35.3 years for Poorland to catch up.

Hasil dari 64^5/6 + 27^2/3 - 81^3/4 adalah<br>tolong bantuannya kakak kakak<br>

NeTakaya

Answer:

Step-by-step explanation:

Given the indicinal expression 64^5/6 + 27^2/3 - 81^3/4

According to indices;

$a^{m/n} = (\sqrt[n]{a}) ^m$

Applying this to the question

$64^{5/6} \\= (\sqrt[6]{64}) ^5\\= 2^5= 32$

Similarly

$27^{2/3}\\= (\sqrt[3]{27}) ^2\\= 3^2\\= 9\\$

Also;

$81^{3/4}\\= (\sqrt[4]{81}) ^3\\= 3^3\\= 27$

Substitute inti the original equation

64^5/6 + 27^2/3 - 81^3/4

= 32 + 9- 27

= 41 - 27

= 14

Hence the required answer is 14
