Answer:

Ancwer is C

Step-by-step explanation:

Answer:

n= -7

Step-by-step explanation:

subtract 3 from both sides,-6n=42,divide both sides by -6

Answer:

[tex]\boxed{n = - 7}[/tex]

Step-by-step explanation:

[tex] \boxed{you \: solve \: by \: making \to n :} \\ the \: subjet \: of \: the \: equation \to \: \\ it \: means \: making \: \to \: n : to \: stand \: on \: its \: own \to \\ - 6n + 3 = 45 \\ - 6n = 45 - 3 \\ - 6 n= 42 \\ \frac{ - 6}{ - 6} n = - \frac{42}{6} \\ \boxed{n = - 7}[/tex]

Answer:

4c+6≤−10

4c+6−6≤−10−6 ... subtract 6

4c≤−16...divide both sides by 4

final: c≤−4

5c-3>2

5c-3>2...add 3

5c>5...divide by 5

c>1

Answer: c

Answer:

The estimated number of bacteria after 20 hours is 40.

Step-by-step explanation:

This is a case where a geometrical progression is reported, which is a particular case of exponential growth and is defined by the following formula:

[tex]n(t) = n_{o}\cdot \left(1+\frac{r}{100} \right)^{t}[/tex] (1)

Where:

[tex]n_{o}[/tex] - Initial number of bacteria, dimensionless.

[tex]r[/tex] - Increase growth of the experiment, expressed in percentage.

[tex]t[/tex] - Time, measured in hours.

[tex]n(t)[/tex] - Current number of bacteria, dimensionless.

If we know that [tex]n_{o} = 30[/tex], [tex]r = 1.4[/tex] and [tex]t = 20\,h[/tex], then the number of bacteria after 20 hours is:

[tex]n(t) = 30\cdot \left(1+\frac{1.4}{100} \right)^{20}[/tex]

[tex]n(t) \approx 39.616[/tex]

[tex]n(t) = 40[/tex]

The estimated number of bacteria after 20 hours is 40.

Answer:

it would probably be 7 hours

Answer:

you have a 1 in 4 chance or 25% chance

Step-by-step explanation:

there is 20 balls and 5 are black, right? And if you do 5/20 it eachs 1/4 or 0.25.

Answer:

the answer is 1,674

Step-by-step explanation:

because if 3hours in 558 miles you multiply the 3hours in 558miles and the answer is 1,674

Substitute x = 3 - 2 cos(θ) and dx = 2 sin(θ) dθ (where "sin" = "sen"). So we have

∫ sin(θ) / (3 - 2 cos(θ)) dθ = 1/2 ∫ 1/x dx

= 1/2 ln|x| + C

= 1/2 ln(3 - 2 cos(θ)) + C

(We can remove the absolute value because -1 ≤ cos(θ) ≤ 1, so 1 ≤ 3 - 2 cos(θ) ≤ 5, and |x| = x when x ≥ 0.)

the graph is (0,2)

Step-by-step explanation:

Answer:

468,119 < 486,191

Step-by-step explanation:

compare the left numbers. Four is equal to four, so go right. 6 is less than 8, so 468,119 < 486,191

Answer:

66.4, 70.4, 223.2

Step-by-step explanation:

make the equation x + (x+4)+ 3x+24=360

then it's 5x+28=360

subtract 28 on both sides

5x=332

then divide by 5 on both sides

x=66.4

then, just plug in the numbers

                      40 seconds

                    = 15 meters per second

Answer:

Yes, it is

Step-by-step explanation:

Yes, because all x terms have null or positive integer exponents:

g(x) = -x^3 + 2x^1 + 8^0.

Answer: You have to save $128 more dollars.

Step-by-step explanation: The iPad costs $353 and you already have $225, so to find the answer you have you subtract what you already have from how much it costs. So 353 - 225 = 128. You need to save up $128 more dollars to get the iPad. (I think this is correct, I tried)

Answer:

The village market

Step-by-step explanation:

Price per can at the village market

= 2.30÷5

= $0.46

Price per can at Best Food

=5.10÷10

= $0.51

Answer:

Village market

Step-by-step explanation:

Find the unit rate at village market and Best food and compare.

Village market:

Rate per can  = 2.30 ÷ 5

                      = $ 0.46

Best food:

Rate per can = 5.10 ÷ 10

                     = 0.51

0.46 < 0.51

Buying can from village market is best buy as that is less priced

Answer:

15.6 meters in a minute

Step-by-step explanation:

Here's why:

1 centimeter= 0.01 meter

So, if you have 26 cm, that equals 0.26 meters.

Now, we know that there are 60 seconds in a minute.

So, we have to do 0.26 times 60 which equals 15.6 meters.

I hope this helps you! :)
