Answer:

When we are dividing exponents, there is this rule:

$\frac{a^n}{a^m}=a^{(n-m)}$

So, in our case we have this:

$\frac{16a^5b^3}{8ab} = \frac{16}{8}a^{(5-1)}b^{(3-1)}$ $=2a^4b^2$

Jojo likes to paint. She estimates the number of paintings she completes using the function P of w equals two thirds times w min

pantera1 [17]

Answer:

$P = \frac{2}{3} [J(y)] - 2$

Step-by-step explanation:

If Jojo completes P number of paintings working w weeks then the relation between P and w is given by $P = \frac{2}{3} w - 2$ . ........ (1)

Again, the function J(y) represents how many weeks per year she spends painting.

So, w = J(y). ...... (2)

Therefore, the composite function which represent how many paintings Jojo completes in a year, is given by

$P = \frac{2}{3} [J(y)] - 2$ (Answer)

Find the volume of a pyramid with a square base, where the perimeter of the base is

Liula [17]

Answer:

33.4 m^3

Step-by-step explanation:

The edge length of the base is 1/4 of the perimeter, so is ...

(10.3 m)/4 = 2.575 m

Then the area of the base is the square of this, or ...

B = (2.575 m)^2 = 6.630625 m^2

The volume is ...

V = (1/3)Bh = (1/3)(6.630625 m^2)(15.1 m) ≈ 33.4 m^3

The volume of the pyramid is about 33.4 cubic meters.

Jake and amber worm at McDonald's they each earn $8 per hour jake works three more hours then amber if jake and amber made a tot

Nadya [2.5K]

Answer:

9 hours

Step-by-step explanation:

Set up the equations: x is the amount of hours Amber worked and y is the hours Jake worked

8x + 8y = 120

y = 3 + x

Substitute the second equation into the first

8x + 8(3+x) = 120

Distribute

8x + 24 + 8x = 120

Combine like-terms

16x + 24 = 120

Subtract 24 on both sides

16x = 96

Divide 16 on both sides

x = 6 (hours Amber worked)

Plug in this x-value into on of the two equations. I will use the second

y = 3 + 6

y = 9
