roni 1/30 t 1/30t

allie 1/75 t 1/75t

If Roni and Allie are working together, Roni will mow .71 of the field.

in a chart,  Roni's rate would be 1/30 and Annie's rate would be 1/75.

both of thier times would be x

and the part of field mowed would be 1/30x for Roni and 1/75x for Annie.

the answer is .71

hope this helps :)

Answer:

53 Million

Step-by-step explanation:

In 1991: t = 0 and A = 45 million

In 2002: t = 11 and p = 51 Million

You're Solving For k:

P = [tex]Ae^{kt}[/tex] In(1.0625) - In( [tex]e^{k*11}[/tex] )

51 = [tex]48^{k*11}[/tex] 0.0606 = k * 11

1.0625 = [tex]e^{k*11}[/tex] 0.0055 ≈ k

In 2008: t = 17

P = [tex]Ae^{kt}[/tex]

P = [tex]48e^{0.0055*17}[/tex]

P = [tex]48e^{0.094}[/tex]

P = 48*1.0986

P ≈ 52.71466 million as the population

P ≈ 53 Million If Rounded

The slope of the graph, in this case, is 3 and it indicates the cost per mile traveled in a taxi. The slope is obtained by dividing the change in total fare by the change in miles traveled.

The correct answer is 'The slope is 3 and it represents the cost per mile traveled'. In this context, the slope of the graph represents the taxi fare rate per mile traveled, meaning for each mile you travel in the taxi, you are charged this amount. To find the slope (m), you usually use the formula m = change in y / change in x. Here, 'y' refers to the total fare, and 'x' refers to the miles traveled.

8x =2x+24

6x = 24

x = 24/6 = 4

 angle 4 = 2(4) +39 = 8+39 = 47

 angle 6 = angle 4

angle 6 = 47 degrees

Answer:

Its B, ≤ 4

Step-by-step explanation:

The volume of a cube with a side length of [tex]4r^3s[/tex] is a monomial expressed as[tex]64r^9s^3[/tex], derived by cubing the side length according to the formula for the volume of a cube.

To express the volume of a cube with the side length[tex]4r^3s[/tex] as a monomial, we use the formula for the volume of a cube, which is [tex]Volume = side^3[/tex]. Therefore, for a cube with side length [tex]4r^3s[/tex], the volume V can be calculated as follows:

[tex]V = (4r^3s)^3 = 4^3 \times (r^3)^3 \times s^3 = 64 \times r^9 \times s^3[/tex]

This simplifies to V = 64r^9s^3, which is the monomial representing the volume of the cube.

Answer:

1 - 2n > 5. The solution set is (-∞, -2)

Step-by-step explanation:

We are dealing here with two problems:

"One less than twice a number" can be written as  [tex]\\1 - 2n[/tex], where n is the unknown number.

If it is not less than five, thus it is greater (no less) than five. Then, the symbol here is  " > " (greater).

As a result: "One less than twice a number is no less than five" could be rewritten as "One less than twice a number is greater than five", or:

[tex]\\1 - 2n > 5[/tex].

The solution set for this inequality is as follows:

[tex]\\ 1-2n > 5[/tex] ⇒

Subtract -1 from each member of the inequality:

[tex]\\ 1-1-2n>5-1 [/tex] ⇒ [tex]\\ -2n>5-1[/tex] ⇒ [tex]\\ -2n>4 [/tex]

Multiply each member of the inequality by [tex]\\-\frac{1}{2}[/tex] (or divide each member by -2). We have to remember here that when we multiply or divide an inequality by a negative number (-n), this inverts the inequality, that is:

[tex]\\ -\frac{1}{2}*(-2)*n< -\frac{1}{2}*4 [/tex]

[tex]\\ 1*n< -\frac{1}{2}*4 [/tex]

[tex]\\ n < -2 [/tex]

The solution set is then [tex]\\ n< -2 [/tex], which is any value less than -2 (not including -2, because is < and not ≤), and we have infinite negative numbers with such a characteristic. We can write it mathematically as an interval notation:

Solution set for [tex]\\1 - 2n > 5[/tex] is [tex]\\ (-\infty, -2)[/tex].

Answer: The answer would be 25/t + 6 = 2t + 1

The scale factor is 3.

The decimal 0.25 can be written in words as zero point two five or twenty five-hundredths .

To understand the value of 0.25 in terms of tenths and hundredths, let's break it down:

The digit 2 is in the tenths place, and it represents two tenths ( 2 / 10 ) or 0.2.

The digit 5 is in the hundredths place, and it represents five hundredths ( 5 / 100 ) or 0.05.

So, in terms of tenths and hundredths, 0.25 can be expressed as zero point two five, where the 2 represents two tenths and the 5 represents five hundredths twenty five-hundredths.

Answer:

This can be checked by looking at the number on the biggest place of the dividend, if it is less than the divisor, the answer will have one less digits place.

Step-by-step explanation:

Answer:

Find out the  how much is his overall budget .

To prove

Let us assume that the overall budget of Mr.Hollins be x.

As given

Mr. Hollins determined that he gives away $800 each month.

If he gives away 16% of his budget.

16% is written in the decimal form.

[tex]= \frac{16}{100}[/tex]

= 0.16

Than the equation becomes

x × 0.16 = 800

[tex]x = \frac{800}{0.16}[/tex]

x = $5000

Therefore the overall budget of Mr.Hollins be $5000 .
