After w weeks , a student has saved 100 + 15w dollars. How much money has the student saved after 3 weeks ?
A$105
B$65
C$120
D$145
Answers
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!!!

Answers
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

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

What was the difference in the starting temperature and the ending temperature
Answers
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.

Answers
what is 16/20 to the nearest hundreth
Answers
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):

Answers
Answer:
560Step-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

From each of the following sets make all possible ordered pairs,
(a) P= {x,y)
(b) X= {1, 2, 3)
Answers
Answer:
All possible ordered pairs are as follows:
{(x, 1), (x, 2), (x, 3), (y, 1), (y, 2), (y, 3)}Step-by-step explanation:
In an ordered pair (x, y),
x is called the first component y is called the second component.Let
P = {x, y}
X = {1, 2, 3}
The number of elements in the set P = n(P) = 2The number of elements in the set X = n(X) = 3So, the number of possible ordered pairs = 2 × 3 = 6
Therefore, all possible ordered pairs are as follows:
{(x, 1), (x, 2), (x, 3), (y, 1), (y, 2), (y, 3)}Let p(x)=x^3+15x^2-8x+2. What is the remainder when p(x) is divided by x-2?

Renee spent 1/8 of the day landscaping around the house. She spent half of the time pulling weeds. What fraction of the day did rehne spend pulling weeds?
Answers
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

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

The radius of a cone is decreasing at a constant rate of 5 centimeters per minute, and the volume is decreasing at a rate of 148 cubic centimeters per minute. At the instant when the radius of the cone is 222 centimeters and the volume is 21 cubic centimeters, what is the rate of change of the height? The volume of a cone can be found with the equation V=1/3πr^2h. Round your answer to three decimal places.
Answers
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.
