Answer:

1300 and 700 respectively.

Step-by-step explanation:

Let x be invested in first account and y be invested in second account.

ATQ, x+y=2000 and 101=(4)*x/100+7*y/100. Solving it will give us x=1300 and y=700

2. For a particular model of a car, a dealer offers 3 sizes of engines, 2 types of stereos, 18 body

Gnesinka [82]

The given details follow the product rule. The different model of the car available are 756.

Given that:

$Engines = 3$

$Stereos = 2$

$Body=18$

$Color = 7$

The different possibility is calculated using the following product rule:

$Total =Engines \times Stereos \times Body \times Color$

So, we have:

$Total = 3\times 2\times 18 \times 7$

$Total = 756$

Hence, there are 756 different models available.

Simplify (2z^5)(12z^3)/4z^4

Sphinxa [80]

Answer:

$6z^{4}$

Step-by-step explanation:

Given in the question an expression,

$\frac{ (2z^5)(12z^3)}{4z^4}$

Step 1

Apply exponential "product rule"

$x^{m}x^{n}=x^{m+n}$

$\frac{ 12(2)z^5)(z^3)}{4z^4}$

$\frac{ (24)z^5)(z^3)}{4z^4}$

$\frac{ 24(z^{(5+3)})}{4z^4}$

$\frac{ 24(z^{8})}{4z^4}$

Step 2

Apply exponential " divide rule"

$\frac{x^{m}}{x^{n}}=x^{m-n}$

$\frac{24/4(z^{8})}{z^4}$

$\frac{6(z^{8})}{z^4}$

$\frac{6(z^{8-4})}{1}$

$6z^{4}$
