Answer:
a) S varies inversely as G
[tex]S\propto\frac{1}{G}[/tex]
or [tex]S=\frac{K}{G}[/tex]
b) S=4 when G=7
Step-by-step explanation:
a) Write the variation.
S varies inversely as G
[tex]S\propto\frac{1}{G}[/tex]
So, We can write: [tex]S=\frac{K}{G}[/tex]
Where k is constant of proportionality
b) Find S when G is 7.
Now, if S=8, G = 3.5 we will find K
[tex]S=\frac{K}{G}\\K=SG\\K=8\times 3.5\\K=28[/tex]
So, value of K= 28
Now, find S when G is 7
[tex]S=\frac{K}{G}\\S=\frac{28}{7}\\S=4[/tex]
So, S=4 when G=7
Write an algebraic expression that represents each word expression. You want to store an equal number of books on each of the 5 shelves on your bookcase. If you have b books, how many books will be on each shelf?
Answer: [tex]\dfrac{b}{5}[/tex]
Step-by-step explanation:
Given: Let b = Total number of books.
Total shelves = 5
Number of books on each shelf = (Total number of books) ÷ (Total shelves)
= b ÷ 5
[tex]=\dfrac{b}{5}[/tex]
The required expression for the number of books on each shelf = [tex]\dfrac{b}{5}[/tex]

A driver drives to school along the same routine Monday through Friday. There is one traffic light on her route . The probability that the light will be red is 65% . What is the probability that she will not have to stop at the light all next week?
Answer:
0.525%
Step-by-step explanation:
Since we are trying to find the probability of a sequence of events we simply need to multiply the probability of each of these events happening separately from one another. We are told that the probability that the light will be red is 65% that means that the probability that it will be green and that the driver will not need to stop is 35%. This probability remains the same every day of the week. Therefore we need to multiply this probability 5 times, one time for each weekday Monday through Friday, but first we need to turn this percentage into a decimal form by dividing it by 100...
35% / 100 = 0.35
0.35 * 0.35 * 0.35 * 0.35 * 0.35 = 0.00525 ...multiply by 100 to get percentage
0.00525 * 100 = 0.525%
Finally, we can see that the probability that she will not have to stop at the light all next week is 0.525%
Draw a rectangle with dimensions that are a third of the rectangle below. Label the sides lengths of your new rectangle.
HELP PLEASE!!
After dilation the new dimensions of the rectangle is drawn and shown in the image attached below.
What is Dilation?Dilation simply refers to the enlargement or reduction of the size of an image.
When an image is enlarge, the original size of the image increases, while when it is reduced, the new image formed will have a size that is smaller than the original image.
To dilate an image, a scale factor is used. If the scale factor is less than 0, it is a reduction, if it is more than 0, it is an enlargement.
To get the length of the sides of the new image, multiply the length of each side of the original image by the scale factor.
In the diagram given, we have the following:
Length of original image = 12 units
Width of original image = 9 units
To create a third of the rectangle given, it means the scale factor for the dilation is 1/3.
Length of new rectangle = 12 units × 1/3 = 4 units
Width of new rectangle = 9 units × 1/3 = 3 units
Thus, after dilation the new dimensions of the rectangle is drawn and shown in the image attached below.

Colbalt-60 has half-life of about 5 years, How many grams of a 300 g sample will remain after 20 years?
Answer:
After 20 years 18.75 gm of sample will remain.
Step-by-step explanation:
The half-life is the time it takes for any amount of Cobalt-60 to decay to half the starting amount.
20 years is 4 times the half-life of 5 years. So there would be
(300 g) / 2⁴ = 18.75 g
remaining after 20 years.
In other words, after 5 years, 300 g decays to 150 g.
After another 5 years (total 10 years), 150 g decays to 75 g.
After another 5 years (total 15 years), 75 g decays to 37.5 g.
After another 5 years (total 20 years), 37.5 g decays to 18.75 g.

Answer:
A = $5183.36
Step-by-step explanation:
Compound Interest
It occurs when the interest is reinvested rather than paying it out. Interest in the next period is then earned on the principal sum plus previously accumulated interest.
The formula is:
[tex]{\displaystyle A=P\left(1+{\frac {r}{n}}\right)^{nt}}[/tex]
Where:
A = final amount
P = initial principal balance
r = interest rate
n = number of times interest applied per time period
t = number of time periods elapsed
Abdul deposited P=$4000 into an account with r=2.6% = 0.026 compounded quarterly. Since there are 4 quarters in a year, n=4. We are required to calculate the amount in the account after t=10 years.
Applying the formula:
[tex]{\displaystyle A=4000\left(1+{\frac {0.026}{4}}\right)^{4*10}}[/tex]
[tex]{\displaystyle A=4000\left(1.0065\right)^{40}}[/tex]
A = $5183.36

Answer:
37.4
Step-by-step explanation:
The most accurate measurement of Pat’s temperature in degrees Celsius is 37.39°.
Given that, Pat has a fever of temperature is 99.3° F.
What is the conversion of Celsius to Fahrenheit?Celsius to Fahrenheit is the conversion of temperature from Celsius unit to Fahrenheit unit. Temperature scales provide a way of measuring how hot or cold a body is. Fahrenheit and Celsius are temperature scales.
The formula to convert Celsius to Fahrenheit is given by: °F = °C × (9/5) + 32.
The formula to convert Fahrenheit to Celsius is C=5/9(F-32)
Now, C= 5/9 (99.3-32)
= 5/9 × 67.3
= 37.39°
Hence, the most accurate measurement of Pat’s temperature in degrees Celsius is 37.39°.

<2 = 121
Step-by-step explanation:
We know that angle 1 and angle 3 form a linear pair, which means they add to 180
7x+2 + 3x+8 = 180
Combine like terms
10x+ 10 = 180
Subtract 10 from each side
10x+10-10 = 180-10
10x = 170
Divide by 10
10x/10 =170/10
x = 17
Angle 1 and angle 2 are vertical angles and vertical angles are equal
<1 = <2 = 7x+2 = 7(17) +2 =119+2=121

hello im ganna do fraccions what is 13\15 + 8\3 + 2\9 =
Answer:
3 34/45
Step-by-step explanation:
The common denominator of these is 45.
13/15 = 39/45
8/3 = 120/45
2/9 = 10/45
Add that up and that is 169/45
Simplify as a mixed number, and it would be 3 34/45
Answer:
169/45
Step-by-step explanation:
First lets do 13/15 + 8/3.
We can multiply 8/3 by 5 to both num and denom for a ration, with the denominator being 15: 40/15.
Then add 13/15 to 40/15 to get 53/15
Now multiply that by 3 to both num and denom to get 159/45. This is to get the least common factor with 9.
2/9 can be multiplied by 5 to both num and denom to get the least common factor with 15: 10/45
Now add 159/45 with 10/45 = 169/45
169/45 is the least it can be simplified so that is the answer.
