can someone please help me im struggling on this one

Answer:

The fraction of the day Rehee spent pulling weeds = 1/16

Step-by-step explanation:

Let us take the fraction representing a whole day to be a whole number - 1

Renee spent 1/8 of the day landscaping around the house.

This means she spent 1/8 X 1 landscaping around the house = 1/8

She spent half of the time pulling weeds.

This means she spent 1/2 of 1/8 of  1 landscaping around the house = 1/16

1/2 X 1/8 X 1 = 1/16

The fraction of the day Rehee spent pulling weeds = 1/16

Answer:

The rate of change for the height of the cone is [tex]-2.849\times 10^{-3}[/tex] centimeters per minute.

Step-by-step explanation:

We derive an expression for the rate of change for the height of the cone by differentiating the volume formula given on statement:

[tex]\dot V = \frac{\pi}{3}\cdot (2\cdot r\cdot h \cdot \dot r + r^{2}\cdot \dot h)[/tex] (1)

Where:

[tex]\dot V[/tex] - Rate of change for the volume of the cone, measured in cubic centimeters per minute.

[tex]r[/tex] - Radius of the cone, measured in centimeters.

[tex]h[/tex] - Height of the cone, measured in centimeters.

[tex]\dot r[/tex] - Rate of change for the radius of the cone, measured in centimeters per minute.

[tex]\dot h[/tex] - Rate of change for the height of the cone, measured in centimeters per minute.

If we know that [tex]\dot V = -148\,\frac{cm^{2}}{min}[/tex], [tex]r = 222\,cm[/tex], [tex]V = 21\,cm^{3}[/tex], [tex]\dot r = -5\,\frac{cm}{min}[/tex], then the rate of change for the height is:

[tex]h = \frac{3\cdot V}{\pi\cdot r^{2}}[/tex] (2)

Where [tex]V[/tex] is the volume of the cone, measured in cubic centimeters.

[tex]h = \frac{3\cdot (21\,cm^{3})}{\pi\cdot (222\,cm)^{2}}[/tex]

[tex]h \approx 4.069\times 10^{-4}\,cm[/tex]

From (1):

[tex]\frac{3\cdot \dot V}{\pi} = 2\cdot r\cdot h\cdot \dot r + r^{2}\cdot \dot h[/tex]

[tex]r^{2}\cdot \dot h = \frac{3\cdot \dot V}{\pi}-2\cdot r\cdot h\cdot \dot r[/tex]

[tex]\dot h = \frac{3\cdot \dot V}{\pi\cdot r^{2}}-\frac{2\cdot h\cdot \dot r}{r}[/tex]

[tex]\dot h = \frac{3\cdot \left(-148\,\frac{cm^{3}}{min} \right)}{\pi\cdot (222\,cm)^{2}} -\frac{2\cdot (4.069\times 10^{-4}\,cm)\cdot \left(-5\,\frac{cm}{min} \right)}{222\,cm}[/tex]

[tex]\dot h = -2.849\times 10^{-3}\,\frac{cm}{min}[/tex]

The rate of change for the height of the cone is [tex]-2.849\times 10^{-3}[/tex] centimeters per minute.

Answer:

Step-by-step explanation:

First we need to find the volume of the cube;

Volume = Length * Width * height

Given;

Length = 3 1/3 in

Width = 2 2/3 in

Height = 2 1/3 in

Volume = 3 1/3  * 2 2/3 * 2 1/3

Volume = 10/3 * 8/3 * 7/3

Volume = 560/3 in^3

To know thw amount of 1/3 in^3 it takes to fill the box, we will take the ratio of the volume to the unit volume;

Ratio = 560/3÷1/3

Ratio = 560/3 * 3/1

Ratio = 560

Hence it will take 560 1/3 in^3 to fill a box with that volume

Answer:

Step-by-step explanation:

The 2-point form of the equation of a line is useful for these problems. It is ...

  y = (y2 -y1)/(x2 -x1)(x -x1) +y1

__

a) The two points are (0, 255) and (9, 480). The equation is ...

  y = (480 -255)/(9 -0)(x -0) +255

  y = 25x +255

__

b) The two points are (0, 450), (9, 90). The equation is ...

  y = (90 -450)/(9 -0)(x -0) +450

  y = -40x +450

__

c) The point where both populations are the same is (3, 330).

__

d) The second population will be eliminated after 11 1/4 seasons.

Answer:

113.04

Step-by-step explanation:

To calculate a circle's area, the formula is Pi R Squared. R is radius. Radius squared would be 36. (6*6) Now, multiplied by Pi, the area would be:  113.04. (36*3.14)

Answer:

113.04

Step-by-step explanation:

The radius of a circle is 6 yards. What is the circle's area?

r=6 yd

Use 3.14 for ​.

square yards

You answered:

113.1

square yards

remember

Use this formula to find the area from the radius.

A=​r2

Use 3.14 as an approximation for ​.

​≈3.14

solve

The radius is 6 yards. Replace r by 6 in the formula.

A

= ​r2

≈ 3.1462

≈ 3.1466

≈ 113.04

The area is about 113.04 square yards.

Answer:

hello the geinus has arrived

Answer:

x = 6

Step-by-step explanation:

This means that they are equivalent to each other.

10 = 30 *Multiply by 3

2 = x

Since we multiplied by 3 to get 30, x is just 2 mulitplied by 3.

x = 6

Answer:

Hi

the answer would be:

10/40 = 2/2+x => if you solve the equation, it'll be equal to : x = 6

I hope that it's correct.

Step-by-step explanation:

Answer:

First, we convert the fraction to a decimal number by dividing the numerator by the denominator:

16 / 20 = 0.800

There are two parts to the decimal number above:

Integer Part: 0

Fractional Part: 800

Now, we will make the Fractional Part just two digits (nearest hundredth) by using our rounding rules.*

In this case, Rule I applies, so 16/20 (or 0.800) rounded to the nearest hundredth in decimal format is:

0.80

Next, we will make 16/20 rounded to the nearest hundredth in fraction format. Since you can divide our decimal format answer above by 1 and keep the same value, you can make it like this:

0.80 = 0.80/1

Then, we multiply the numerator and denominator by 100 to get rid of the decimal point:

(0.80 x 100) / (1 x 100) = 80/100

That's it. 16/20 rounded to the nearest hundredth is displayed below (simplified if necessary):

Answer:

The student will have $145

Step-by-step explanation:

The student would already have $100 and if you take 15 times the number of weeks, 3 weeks. 15 times 3 is $45. $100 + $45 = $145

Answer:

D. $145

Step-by-step explanation:

In order to find out the answer to the equation 100 + 15w = ? we have to multiply 15 by the 3 weeks the student has saved up 15 dollars to get the total money they have saved by saving 15 dollars per week:

15 * 3 = 45

we then add the 100 dollars that was already saved up to 45

100 + 45 = $145

So after 3 weeks $145 have been saved up

Hope this helps!!!

Answer:

third option

Step-by-step explanation:

The n th term of a geometric sequence is

[tex]a_{n}[/tex] = a₁ [tex](r)^{n-1}[/tex]

where a₁ is the first term and r the common ratio

[tex]\frac{1}{4}[/tex] [tex](2)^{k-1}[/tex] ← is in this form

with a₁ = [tex]\frac{1}{4}[/tex] and r = 2

Answer:

Option B

Step-by-step explanation:

Slope of the line is calculated by the formula:

[tex]m=\frac{y_2-y_1}{x_2-x_1}\\\\[/tex]

We have the points ( -2 , 4) and (3 , -5) so plug in the values in the formula:

[tex]m=\frac{y_2-y_1}{x_2-x_1}\\\\m=\frac{-5-4}{3-(-2)}\\\\m=\frac{-9}{5}\\[/tex]

so the slope(m) equals -9/5

Answer:

g(2) = -9

Step-by-step explanation:

g(2) = -1 x g(1) - 4

g(2) = -1 x 5 - 4

g(2) = -5 - 4

g(2) = -9

Answer:

You subtract the final temperature from the starting temperature to find the difference. So if something starts at 50 degrees Celsius and finishes at 75 degrees C, then the change in temperature is 75 degrees C – 50 degrees C = 25 degrees C. For decreases in temperature, the result is negative.
