Ok so u have to multiply for this one

Work *Jake*:

So he spends 2 hours on each assignment. He has 3 assignments so u have to do :
2*3=6
 
He spend 6 hours a day doing home work so now u have to multiply that by 30:
6*30=180

Work *Orlando*:

So he spends 2 hours on each homework. He has 2 sheets each do so u have to multiply 2 and 2: 
2*2=4

He spends 4 hours a day doing homwork so u  have to multiply it by 30: 
4*30=120


Answer:
 

So Jake spends 130 hours
Orlando spends 120 hours 

Add both together:
120+130=250

They spend 250 hours together on work in 30 days/

Jamie has an old CD that she wants to use for an art project. The circumstance of the CD is 22 cm and she would like to cut from
nirvana33 [79]

Answer: 10 cm


Step-by-step explanation:

The circumference of the CD = 22\pi


We know that the formula of the circumference is:


Circumference = 2\pi r


We will substitute the value of circumference to find the radius:


22 pi = 2 x pi x r


r = 11


Therefore its radius will be 22 / 2 = 11 cm


Jamie wants to cut the CD from the middle of the CD to one side but leaving one cm. To find the measurement of the cut portion, we will subtract 1 from 11 to get:


11 - 1 = 10 cm

Plz help me, thank you
Kruka [31]

Answer:

P=40(1.03526)^{t}

Step-by-step explanation:

<u>Exponential Growth </u>

The natural growth of some magnitudes can be modeled by the equation:

P=P_o(1+r)^{t}

Where P is the actual amount of the magnitude, Po is its initial amount, r is the growth rate and t is the time.

The initial number of bacteria is Po=40 and it doubles (P=2Po) at t=20 min. With that point we can find the value of r:

2P_o=P_o(1+r)^{20}

Simplifying:

(1+r)^{20}=2

Solving for 1+r:

1+r=\sqrt[20]{2}

1+r=1.03526

The exponential function that models the situation is:

\mathbf{P=40(1.03526)^{t}}
