Answer:

N(t) = N0/2^t

Step-by-step explanation:

Given that:

Number of cells present after t hours = N

Let initial number of cells = N0

Using the exponential decay relation:

N(t) = N0(1/2)^t

N(t) = N0/2^t

Hence, the number of cells N present after t hours is N(t) = N0/2^t.

I'm not quite 'out there in the real world' but whenever I'm limited on money and whatnot, instead of trying to go ahead and add it all up by the exact price I'll round it up to the nearest dollar. Sometimes I'll even round it up two dollars. If it's something like '$25.98', I'll figure $27.00. That always helps me not spend as much.

Making a list and strictly following the list helps as well. I wouldn't try to spend money on things unessential, or things that you really don't have the money for.

A box and whiskers chart divides the data set into 4 equal parts called quartiles. (second option)

A box and whiskers chart is used to study the distribution and level of a set of scores. The values are distributed into 4 groups. Each group has a value of 25%

The whiskers represent the minimum and the maximum values. On the box, the first line to the left represents the lower quartile. 25% of the score represents the lower quartile. The next line on the box represents the median. 50% of the score represents the median. The third line on the box represents the upper quartile. 75% of the scores represents the upper quartile.

Jada travels faster at a speed of 45mph

Step-by-step explanation:

Jada travels faster at a speed of 45mph

When you divide the overall miles from the time it takes you get the miles per hour.

Jada: 135/3= 45

Andre: 228/6= 38

Jada travels at 45mph as Andre travels at 38mph.

Hope this helps!

Answer:

45

Step-by-step explanation:

Answer:

The values are a=6, b=8

Step-by-step explanation:

The following system of equations

ax - by = 4

bx - ay = 10

Has the solution x=2, y=1. Substituting:

2a - b = 4      [1]

2b - a = 10      [2]

Multiply [1] by 2:

4a - 2b = 8

Add with [2]:

3a = 18

a = 18/3 = 6

a = 6

From [1]:

2*6 - b = 4

b = 12 - 4

b = 8

The values are a=6, b=8

Step-by-step explanation:

To subtract fractions, find the LCD and then combine.

506

Please give me brainiest and also add me please.

Answer:

506

Step-by-step explanation:

First, we have to solve 8 to the power of 3 according to PEMDAS, which will give us 512.

Since we have to follow PEMDAS or GEMDAS (whichever you know), we will have to multiply 9 by 2 next. That will give us the equation: 512 - 18 / 3

Then we have to divide 18 by 3 to give us 6 which will give us the equation: 512 - 6 which we can solve to get 506

Answer:

The ordered pair (-6, -1) is the only solution.

Step-by-step explanation:

-6x + y = 35

Let's plug in the points.

(-1, -7) --> -6(-1) - 7 = 6 - 7 = -1 which does not equal 35

(-6, -1) --> -6(-6) -1 = 35

(-1, -6) --> -6(-1) - 6 = 0 which does not equal 35

(-7, -1) --> -6(-7) - 1 = 41 which does not equal 35

Answer:

The missing length is 12

Step-by-step explanation:

Required

Determine the missing length (LS)

If RS = 28 and KS = 14

Then

[tex]KR = RS - KS[/tex]

[tex]KR = 28 - 14[/tex]

[tex]KR = 14[/tex]

The sides of the given shape are directly proportional.

This implies that:

[tex]KS : LS = RS : QS[/tex]

[tex]KS = 14[/tex]

[tex]RS = 28[/tex]

[tex]QS = 12 + LS[/tex]

[tex]LS = ??[/tex]

So, the expression becomes:

[tex]14 : LS = 28 : 12 + LS[/tex]

Represent as a fraction

[tex]\frac{14}{LS} = \frac{28}{12 + LS}[/tex]

Cross Multiply:

[tex]14(12 + LS) = 28 * LS[/tex]

Divide through by 12

[tex]12 + LS = 2 * LS[/tex]

[tex]12 + LS = 2 LS[/tex]

Collect Like Terms

[tex]2LS - LS = 12[/tex]

[tex]LS = 12[/tex]

The length of the missing side is 12

Answer:

srry but search 12 z6xs

Step-by-step explanation:

(a) The total interest that Ravi will have to pay is $120.  (b) The total repayment amount will be $920.

a) The interest rate is 5% per year, so Ravi will pay 5% * 800 = $40 per year in interest.

Since he borrowed the money for 3 years, he will pay a total of 3 * 40 = $120 in interest.

b) The total repayment amount will be the principal amount of $800 plus the interest of $120, for a total of 800 + 120 = $920.

Simple interest formula: I = P * r * t

Where:

I is the interest

P is the principal amount

r is the interest rate

t is the time in years

Interest per year: 5% * 800 = $40

Total interest: 3 * 40 = $120

Total repayment amount: 800 + 120 = $920

Answer: 530.3

Step-by-step explanation:

Difference means to subtract

620-89.7=530.3

Answer:

530.3

Step-by-step explanation:

You want to subtract 620-89.7. If you want to use the standard algorithm you have 620.0-89.7. You "borrow" from the 2 in the tens place, then "borrow" from the ones place. To subtract 10-3 tenths. Then you subtract the ones place which is 9-9=0 ones. Now you subtract 62-8=53 tens. So you have 530.3 as the difference.
