A certain type of bacteria doubles every 4 hours. If you started with 37 bacteria, how many would you have after 12 hours?

Answer:

B

Step-by-step explanation:

Based on the amount that Sam saves and his living expenses, the amount he needs to save and the length of time it will take him to do so is B. 5,136; Approximately 24 months.

= Fixed essential expenses + Variable essential expenses

= 1,292 + 420

= $1,712

Sam needs to save three times his expenses:

= 1,712 x 3

= $5,136

= Amount to be saved / Amount saved monthly

= 5,136 / 210

= 24 months approximately.

________________________________________________________

The question is:

Using his essential expenses as a guideline, how much will Sammy need to save if he wants to have 3 times the amount of his living expenses in the bank as part of his emergency savings. How long will it take him to achieve his goal?

a. $1,712; approximately 8 months

b. $5,136; approximately 24 months

c. $6,486; approximately 30 months

d. $2,162; approximately 6 months

Answer:

Step-by-step explanation:

So because Howard wants to divide the granola evenly among all of his friends, we have to divide the amount of pounds he has by the number of friends he has.

(3/5) / 4

Dividing by four is the same as multiplying by the reciprocal of 4 which is 1/4.

So (3/5) * (1/4) is 3/20 which is .15 pounds

Answer:

I got 5^10 x 2^14 x 3

Step-by-step explanation:

1. Do a tree to find 480 as a product of its prime factors

2. You should get 480= 5x2x3x2x2x2x2

3. 10 expressed as a product of its prime factors is 5x2

4. so 10^9 expressed as a product of its prime factors would be

5x2x5x2x5x2x5x2x5x2x5x2x5x2x5x2x5x2

5. You can then write out 480x10^9 as a product of its prime factors

5x2x3x2x2x2x2x5x2x5x2x5x2x5x2x5x2x5x2x5x2x5x2x5x2

6. change this to use powers

5^10 x 2^14 x 3

N = 5^(10) × 2^(14) × 3

This is about prime factors

By definition, a prime factor is a factor of a number and that factor is also a prime number.

A prime number is one that is divisible by only itself and 1.

The number we have is; 480 × 10^(9)

Now, let's list the prime factors or 480 and they are;

2, 3, 5

Now, using these prime factors alone to get 480, we have;

5 × 3 × 2 × 2 × 2 × 2 × 2 = 480

In powers, gives;

5 × 3 × 2^(5)

Now,the 10^(9) with the 480 can also be expressed in terms of it's prime factors which are 2 and 5 as;

(5 × 2)^(9)

Expanding this gives; 5^(9) × 2^(9) = 10^(9)

Thus;

480 × 10^(9) = 5 × 3 × 2^(5) × 5^(9) × 2^(9)

This gives;

5^(10) × 2^(14) × 3

x= 13

Step-by-step explanation:

3x-4+20= 55

combine like terms:

3x+16= 55

subtract 16 from both sides:

3x = 39

divide 3 to both sides:

x= 13

Answer:

x = ±6

General Formulas and Concepts:

Pre-Algebra

Algebra II

Step-by-step explanation:

Step 1: Define

-x² = -36

Step 2: Solve for x

Step 3: Check

Plug in x to verify it's a solution.

Here we see that both -6 and 6 do indeed work as solutions.

∴ x = ±6 are both solutions to the equation.

Answer:

x ≥ - 3

Step-by-step explanation:

Step 1:

- 7x - 13 ≥ 8       Equation

Step 2:

- 7x ≥ 21      Add 13 on both sides

Step 3:

x ≥ 21 ÷ - 7      Divide

Answer:

x ≥ - 3

Hope This Helps :)

Answer:     x≤−3

Step-by-step explanation:

So first you  -7*x-13-(8)≥0

then you are supposed to pull out like the factors  -7x - 21  =   -7 • (x + 3)

then you divide both sides by -7 then you flip the inequality sign remember that :). then subtract 3 from both sides. and then you got  x ≤ -3 So I really hoped this helped :)

Answer:

1) Measure angle QWT and TWX are complementary because their measures add up to 90 degrees.

2) Both measure angles add up to 90 degrees because they're complementary.

3) Angle QWT = 2x and angle TWX = x + 6, and since angles QWT + TWX = 90 then 2x + x + 6 = 90.

4) (Made up?:) Angle measure QWX = 90. The quarter-turn, or the small square, indicates that the angle is 90 degrees.

5) (?)

6) x = 28 because it fulfills the equation, 2x + x + 6 = 90, or 3x + 6 = 90. 90 - 6 is 84, and 84/3 is 28.

Answer:

{x,y}={31,4}

Step-by-step explanation:

x-8y = -1  x-6y = 7

Answer:

first we find the value of 'y' so

x-8y=-10+8y

x=-10+8y

-2(-10+8y)-6y=-24

20-16y-6y=-24

20-22y=-24-20

-22y=-44

y=2

then also we can find the value of 'x'

-2x-6y=-24

2x-6(2)=-24

2x-12= -24

2x= -24+12

x= -12

Step-by-step explanation:

Answer:

54

Step-by-step explanation:

What the shorthand is telling you is wherever you see an x on the right, you put in -8

f(x) = 6(1- x)

f(-8) = 6(1 - - 8)

f(-8) = 6(1+8)

f(-8) = 6*9

f(-8) = 54

radius (r) = 8.7 cm

Plug in the values into the formula

Area of sector = [tex] \frac{260}{360} \times \pi 8.7^2 [/tex]

Area of sector = [tex] \frac{260 \times \pi 75.69}{360} [/tex]
