Answer:

A

Step-by-step explanation:

This can be rearranged as 4^3 * 1/(4^6)

or (4^3)/(4^6)

This can be changed to:

(4^3)/((4^3)*(4^3)

Which is equal to 1/(4^3)

or

4^(-3)

Answer:

It takes 8.7 hours for there to be 3300 bacteria present.

Step-by-step explanation:

Exponential equation for population growth:

The exponential equation for population growth is given by:

[tex]P(t) = P(0)(1+r)^t[/tex]

In which P(0) is the initial population and r is the growth rate.

2400 bacteria are placed in a petri dish.

This means that [tex]P(0) = 2400[/tex]

So

[tex]P(t) = P(0)(1+r)^t[/tex]

[tex]P(t) = 2400(1+r)^t[/tex]

The conditions are such that the number of bacteria is able to double every 19 hours.

This means that [tex]P(19) = 2P(0)[/tex]. We use this to find 1 + r.

[tex]P(t) = P(0)(1+r)^t[/tex]

[tex]2P(0) = P(0)(1+r)^{19}[/tex]

[tex](1+r)^{19} = 2[/tex]

[tex]\sqrt[19]{(1+r)^{19}} = \sqrt[19]{2}[/tex]

[tex]1 + r = 2^{\frac{1}{19}}[/tex]

[tex]1 + r = 1.03715504445[/tex]

So

[tex]P(t) = 2400(1+r)^t[/tex]

[tex]P(t) = 2400(1.03715504445)^t[/tex]

How long would it be, to the nearest tenth of an hour, until there are 3300 bacteria present?

This is t for which [tex]P(t) = 3300[/tex]. So

[tex]P(t) = 2400(1.03715504445)^t[/tex]

[tex]2400(1.03715504445)^t = 3300[/tex]

[tex](1.03715504445)^t = \frac{3300}{2400}[/tex]

[tex]\log{(1.03715504445)^t} = \log{\frac{33}{24}}[/tex]

[tex]t\log{1.03715504445} = \log{\frac{33}{24}}[/tex]

[tex]t = \frac{\log{\frac{33}{24}}}{\log{1.03715504445}}[/tex]

[tex]t = 8.7[/tex]

It takes 8.7 hours for there to be 3300 bacteria present.

Step-by-step explanation:

Given

Represent each friend with the first letter of their name

So:

[tex]A + B + C =200[/tex]

[tex]B + C + D = 215[/tex]

[tex]C + D +E= 224[/tex]

[tex]A + B + C + D + E = 350[/tex]

[tex]D , E > C[/tex]

Substitute: [tex]A + B + C =200[/tex] in [tex]A + B + C + D + E = 350[/tex]

[tex]200 + D + E = 350[/tex]

Collect like terms

[tex]D + E = 350-200[/tex]

[tex]D + E = 150[/tex]

Make D + E the subject in [tex]C + D +E= 224[/tex]

[tex]D + E = 224 - C[/tex]

Substitute [tex]D + E = 224 - C[/tex] in [tex]D + E = 150[/tex]

[tex]224 - C = 150[/tex]

Collect like terms

[tex]C = 224 - 150[/tex]

[tex]C = 74[/tex]

Substitute [tex]C = 74[/tex] in [tex]A + B + C =200[/tex] and [tex]B + C + D = 215[/tex]

[tex]A + B + 74 = 200[/tex]

[tex]A + B =- 74 + 200[/tex]

[tex]A + B =126[/tex]

[tex]B + 74 + D = 215[/tex]

[tex]B + D = -74 + 215[/tex]

[tex]B + D = 141[/tex]

So, we have:

[tex]A + B =126[/tex]

[tex]B + D = 141[/tex]

[tex]D + E = 150[/tex]

We have: [tex]D , E > C[/tex]

i.e.

[tex]D , E > 74[/tex] and [tex]D + E = 150[/tex]

For [tex]D , E > 74[/tex] and [tex]D + E = 150[/tex] to be true,

[tex]D = E = 75[/tex]

i.e.

[tex]75 + 75 = 150[/tex]

So, we have:

[tex]D = 75[/tex]

[tex]E = 75[/tex]

[tex]B + D = 141[/tex]

[tex]B + 75 = 141[/tex]

[tex]B = 141 - 75[/tex]

[tex]B = 66[/tex]

[tex]A + B =126[/tex]

[tex]A + 66 = 126[/tex]

[tex]A = 126 - 66[/tex]

[tex]A = 60[/tex]

Answer: 160

Step-by-step explanation:

Based on the information given in the question, let the total reviews left for the product be represented by x.

Therefore, 65% of x = 104

65% × x = 104

0.65 × x = 104

0.65x = 104

x = 104/0.65

x = 160

Therefore, 160 reviews were left for the product.

Answer:

It would take 4 years. The formula for continuously compounded interest is: where P is the principal, r is the interest rate as a decimal number, and t is the number of years.

Step-by-step explanation:

You deposit $800 in an account that pays 3.6% annual interest compounded quarterly. after 11 years your balance first exceed $1200.

If n is the number of times the interested is compounded each year, and 'r' is the rate of compound interest annually, then the final amount after 't' years would be:

[tex]a = p(1 + \dfrac{r}{n})^{nt}[/tex]

You deposit $800 in an account that pays 3.6% annual interest compounded quarterly.

[tex]a = p(1 + \dfrac{r}{n})^{nt}[/tex]

[tex]1200 = 800(1 + \dfrac{3.6}{4})^{4t}\\\\300 = (1 + 0.9)^{4t}\\\\t = 11.4[/tex]

28.3 (b)

Step-by-step explanation:

To solve circumference, you will need to use the equation C = 2 *pi* r

for this, we will use 3.14 for pi and the radius is 4.5 so this is how we need to solve it

C= 2 pi (4.5)             Solve 2*4.5

C= 9 pi                     Now we input 3.14 for pi and multiply

C= 9(3.14)

C= 28.26                  Now we round to the nearest tenth to get

C=28.3

The monthly rate of interest is 0.0074. Therefore, option C is the correct answer.

An interest rate tells you how high the cost of borrowing is, or high the rewards are for saving. So, if you're a borrower, the interest rate is the amount you are charged for borrowing money, shown as a percentage of the total amount of the loan.

The given rate of interest is 8.9%.

The monthly payment formula is M = Pr(1+ r)ⁿ/(1+ r)ⁿ - 1

Here, rate of interest

= 8.9%/12

= 0.089/12

= 0.0074

Therefore, option C is the correct answer.

juzt find the scale factors of the two numbers given (120 and 96).

Step-by-step explanation:

Answer:

Here is the picture

Step-by-step explanation:

The number lies between x-values 4 and 6 and y-values 6 and 9.

Coordinates are a pair of integers (Cartesian coordinates), or occasionally a letter and a number, that identify a certain place on a grid, often referred to as a coordinate plane.

Given that scatter plot lies in quadrant 1 of a coordinate plane, and the 14 points are plotted in the first quadrant.

We need to find the range of x and y values for this scatter plot.

The x values of the 14 points are given as;

2, 4, 4,1, 5, 5, 5, 5, 6, 6, 7, 8, 9.5, 9.5

The y values of the 14 points are given as;

5, 6, 9, 7.2, 6, 6.8, 8, 9, 7, 8.5, 10, 10.5, 9.5, 11.4

We can conclude that that most of the points are clustered between x-values 4 and 6 and y-values 6 and 9.

Therefore, the points are clustered between the x-values 4 and 6 and y-values 6 and 9.

Answer:

Distances:

A=1/2

B= 1

C= 3/2

Heights:

D= 1

E= 0

F= -1

Step-by-step explanation:

The distances asked in the circle are a = 1 / 2 π, b = 1π, and c = 3 / 2 π.

Distance is a numerical or occasionally qualitative measurement of how far apart objects or points are. In physics or everyday usage, distance may refer to a physical length or an estimation based on other criteria.

The complete movement of an object, regardless of direction, is referred to as distance.

The amount of ground a thing travels from its starting point to its destination is also referred to as distance.

Distance is the total movement of an object without any regard to direction. We can define distance as to how much ground an object has covered despite its starting or ending point.

Given, is a table defining the relations between the distance and the radius and time in references to a circle,

we need to find the distances, according to the question asked,

Since, we know that,

The time, t = π / 2 sec,

Also,

Calculate the distance by using the formula given below,

Distance = radius x time

So, for distance, a = 1 × π / 2 =  π / 2

for distance, b = 1 × π =  π

for distance, c = 1 × 3 π / 2 =  3 π / 2

Therefore,

We get, the distance of a = 1 / 2 pi, b = 1 pi, and c = 3 / 2 pi.

Hence, the distances asked in the circle are a = 1 / 2 π, b = 1π, and c = 3 / 2 π.
