Answer:

$\dfrac{2x}{3a^2}$

Step-by-step explanation:

$\dfrac{3a^4b}{2x}\cdot\dfrac{4x^2}{9a^6b}=\dfrac{3\cdot 4}{2\cdot 9}a^{4-6}b^{1-1}x^{2-1}=\dfrac{2x}{3a^2}$

The applicable rules of exponents are ...

(a^b)(a^c) = a^(b+c)
a^-b = 1/a^b

Answer:

About 34 workers

Step-by-step explanation:

200/30 to find on average how many trees can be carved by one worker

The answer is 6.666, so just 6

Then 6*4=24 to figure out how many more trees can be carved by (4 more) workers

So, add 4 to 30 and about 224 trees can be carved.

Answer:

1/8

Step-by-step explanation:

The slope equation for this problem is

y2-y1

--------

x2-x1

So the y2=4, y1=3, x2=8, and x1=0

4-3 =1

----- --

8-0 =8

Which is 1/8

Answer:

The required expression is $\frac{y}{4}-3$ .

The value of the expression when y=20 is 2.

Step-by-step explanation:

Consider the provided phase.

3 less than the quotient of a number y and 4

The quotient of a number y and 4 can be written as: $\frac{y}{4}$

Now 3 less than the quotient of a number y and 4 can be written as:

$\frac{y}{4}-3$

Hence, the required expression is $\frac{y}{4}-3$ .

Now evaluate when y=20.

Substitute y=20 in above expression.

$\frac{20}{4}-3$

$5-3$

$2$

Hence, the value of the expression when y=20 is 2.

Harlamova29_29 [7]

Answer:

25.133 units

Step-by-step explanation:

Since the density ρ = r, our mass is

m = ∫∫∫r³sinθdΦdrdθ. We integrate from θ = 0 to π (since it is a hemisphere), Φ = 0 to 2π and r = 0 to 2 and the maximum values of r = 2 in those directions. So

m =∫∫[∫r³sinθdΦ]drdθ

m = ∫[∫2πr³sinθdθ]dr ∫dФ = 2π

m = ∫2πr³∫sinθdθ]dr

m = 2π∫r³dr ∫sinθdθ = 1

m = 2π × 4 ∫r³dr = 4

m = 8π units

m = 25.133 units
