ANSWER:
1/12 of the cereal box
STEP-BY-STEP EXPLANATION:
In this case we must divide the amount that we have, that is, half a box of cereal by the number of portions that are desired equal, that is, 6
Therefore, we are left with:
[tex]\frac{\frac{1}{2}}{6}=\frac{1}{2\cdot6}=\frac{1}{12}[/tex]That is, for each day, you will have to eat 1/12 of the cereal box

Given:
There are given that the 209 ounces to convert into the decigram.
Explanation:
According to the concept:
To convert the ounces into the decigram, we need to multiply the mass values by 283.
That means,
The value of 1 ounce is 283 decigram
So,
[tex]\begin{gathered} 209ounces=209\times283decigram \\ =59147decigram \end{gathered}[/tex]Final answer:
Hence, the value of the 209 ounces is 59147 decigrams.
L) Point A bisects CR. CA = 8x + 1 and AR = 6x+13.Find CA.34927
We will investigate some application of line bisectors.
We have a line segment denoted as ( CR ). A point ( A ) is said to be bisecting the line segment.
Line bisection involves the process of equally dividing the entire line segment in two equal halves! We can also represent this scenario graphically for clearification:
We can also represent line bisection mathematically in terms of two smaller divisions ( CA and AR ) as follows:
[tex]Bi\sec tion\colon\text{ |CA| = |AR| = }\frac{|CR|}{2}[/tex]Where, the quantities are expressed as magnitudes/lengths of each segment indicated.
We are given expressions for bifurcated line segments |CA| and |AR| in terms of variable ( x) as follows:
[tex]\begin{gathered} |CA|\text{ = 8x + 1} \\ |AR|\text{ = 6x + 13} \end{gathered}[/tex]Now we will use the expression given for each smaller division of line |CR| and plug it in the general " Bisection " expression developed above:
[tex]\begin{gathered} |CA|\text{ = |AR|} \\ 8x\text{ + 1 = 6x + 13} \end{gathered}[/tex]We have constructed an equation with a single variable ( x ). We can solve this equation for the variable ( x ) using basic mathematical operations as follows:
[tex]\begin{gathered} 8x\text{ - 6x = 13 - 1} \\ 2x\text{ = 12} \\ x\text{ = 6} \end{gathered}[/tex]Once we have solved for the variable ( x ). We will again use the defined expression for each smaller segments and determine the magnitudes as follows:
[tex]\begin{gathered} |CA|\text{ = 8}\cdot(6)\text{ + 1 } \\ |CA|\text{ = 49 units} \\ \\ |AR|\text{ = 6}\cdot(6)\text{ + 13 } \\ |AR|\text{ = 49 units} \\ \\ |\text{ CR | = 2}\cdot|CA|\text{ = 2}\cdot49 \\ |\text{ CR | = 98 units} \end{gathered}[/tex]Amount of money in Ivanna's account and the amount of money in Brian's account and write the equation
Given
Starting amount of Ivanna = $180
put per month = $70
Starting amount of Brian = 0
put per month = $100
Find
Amount of money in Ivanna's account
the amount of money in Brian's account
equation to show when the two accounts have the same amount of money
Explanation
Let x be the number of months after today.
so, according to the question ,
Amount of money in Ivanna's account = starting amount + amount per month.
so , 180 + 70x
amount of money in Brian's account = 0 + 100x = 100x
equation to show when the two accounts have same amount of money =
[tex]180+70x=110x[/tex]so ,
[tex]\begin{gathered} 180=110x-70x \\ 180=40x \\ x=4.5 \end{gathered}[/tex]so , in 4.5 months both have same money
Final Answer
Hence ,
Amount of money in Ivanna's account = 180 + 70x
Amount of money in Brian's account = 110x
Equation to show when the two accounts have same amount of money =
[tex]180+70x=110x[/tex]Convert percent to fraction and simplify if possible 11% =
To convert percent to fraction divide it by 100
Then to change 11% to a fraction divide 11 by 100

11% = 11/100 in the simplest form

We can break apart the figure into 4 separate figures and find the area of each of these individual figures. Then sum to get area of total figure.
We break apart the figure as shown below:
First,
Area of Triangle = 0.5 * base * height
Area of Rectangle = base * height
Now, let's find each of the Areas A through D:
Area of A:
To find the base of this triangle, we have to use pythagorean theorem. By which we can write:
[tex]b^2+4^2=6^2[/tex]Where b is the base. let's solve for b:
[tex]\begin{gathered} b^2+16=36 \\ b^2=36-16 \\ b^2=20 \\ b=\sqrt[]{20} \\ b=\sqrt[]{4}\sqrt[]{5} \\ b=2\sqrt[]{5} \end{gathered}[/tex]Area is
[tex]\begin{gathered} 0.5\cdot\text{base}\cdot\text{height} \\ =\frac{1}{2}\cdot2\sqrt[]{5}\cdot4 \\ =4\sqrt[]{5} \end{gathered}[/tex]Area of B:
This is a rectangle with base = 10 and height 4, so the area is:
Area = 4 * 10 = 40
Area of C:
Area of C is exactly same as area of B, base is 10 and height is 4. So,
Area = 4 * 10 = 40
Area of D:
Like area of A, we have to find the base of the triangle first, using pythagorean theorem. We can write:
[tex]\begin{gathered} b^2+4^2=4.5^2 \\ \end{gathered}[/tex]Solving for b:
[tex]\begin{gathered} b^2+4^2=4.5^2 \\ b^2+16=20.25 \\ b^2=\frac{17}{4} \\ b=\frac{\sqrt[]{17}}{\sqrt[]{4}} \\ b=\frac{\sqrt[]{17}}{2} \end{gathered}[/tex]Now, area of triangle is:
[tex]A=\frac{1}{2}(\frac{\sqrt[]{17}}{2})(4)=\sqrt[]{17}[/tex]Area of whole figure:
[tex]\begin{gathered} 4\sqrt[]{5}+40+40+\sqrt[]{17} \\ =80+4\sqrt[]{5}+\sqrt[]{17} \end{gathered}[/tex]Since mulch costs $3 per square feet, we have to multiply the area by "3", so we have:

if Sarah has 98 baseball cards in her collection for birthday her she's given 78 new cards and she sold 108 cards how many baseball cards does Sarah have left
68
1) Gathering the data
Sarah has 98 cards
She's given 78 then we can add
98 +78 = 176 cards
2) And right after that Sarah sold 108 cards, so now we can write
176 -108 = 68
3) Finally, Sarah now has 68 baseball cards left.
The mean life of a television set is 97 months with the variance of 169. If a sample of 59 televisions is randomly selected what is the probability that the sample mean would be less than 100.9 months? Round your answer to four decimal places if necessary
Given that the mean life of a television set is 97 months, you can set up that:
[tex]\mu=97[/tex]You also know that the variance is:
[tex]\sigma^2=169[/tex]You can find the standard deviation by taking the square root of the variance. Then:
[tex]\sigma=\sqrt{169}=13[/tex]You need to find:

Which car traveled at the slowest rate? a.750 miles in 10 hours b. 800 miles in 12 hours c. 450 miles in 6 hours d.1000 miles in 14 hours e. 1000 miles in 14 hours
The car with the smallest speed (or slowest rate) exists the car with 800 miles in 12 hours.
What is meant by rate of speed?The ratio of the distance traveled and the time it took to travel that distance yields the rate at which cars move (also known as the speed).
To determine each unit rate (number of miles traveled in 1 hour). To determine the unit rate, we will divide the distance by the time.
rate = distance/time
Substitute the values in the above equation, we get
Then, for each car we will the speeds:
a) S = 750 mi/10 h = 75 mi/h
b) S = 800 mi/12 h = 66.66 mi/h
c) S = 450 mi/6 h = 75 mi/h
d) S = 1000 mi/14 h = 71.428 mi/h
Then we can see that the car with the smallest speed (or slowest rate) is the car with 800 miles in 12 hours.
Therefore, the correct answer is option b) 800 miles in 12 hours.
