10 yellow eggs out of 12 colored eggs ratios
Final answer:
The question asks for the ratio of yellow eggs to colored eggs, which is 10 yellow eggs to 12 colored eggs. Simplifying the ratio, we get 5:6. This concept of ratios is also seen in Mendel's genetic experiments with plants, where traits are passed in specific ratios like 3:1.
Explanation:
In mathematical terms, a student's question regarding the ratio of yellow eggs to the total number of colored eggs can be answered using simple division to derive a fraction or ratio. Given that there are 10 yellow eggs out of 12 colored eggs, the ratio can be expressed as 10:12.
However, ratios should be simplified to their smallest form to be more understandable; therefore, this ratio simplifies to 5:6 since both numbers can be divided by 2.
When looking at historical experiments, such as the ones conducted by Mendel, we find that phenotypic ratios play a significant role in understanding genetics. Mendel observed that traits could manifest in a specific ratio, like a 3:1 ratio for dominant to recessive traits. The ratios observed in the experiments provided can serve as examples to understand how ratios represent the occurrence of certain outcomes over others.
In this case, the ratio of yellow to green seeds in Mendel's experiment can serve as an analogy to understand the ratio of yellow eggs: both ratios quantitatively describe the presence of a certain characteristic compared to another.
CECE HIKING ON A MOUNTAIN AND STOPS AT 15 5/8 FEET ABOVE SEA LEVEL .THE BASE OF THE MOUNTAIN IS 10.2 FEET BELOW SEA LEVEL .WHAT IS THE VERTICAL DISTANCE BETWEEN CECE AND THE BASE OF THE MOUNTAIN?
Answer:
The vertical distance is 25.825 ft
Step-by-step explanation:
we know that
To find out the vertical distance between Cece and the base of the mountain, subtract the height of the base of the mountain from the height of Cece
Let
x -----> the height of Cece
y ----> the height of the base of the mountain
we have
[tex]x=15\frac{5}{8}\ ft[/tex] ----> is positive because is above sea level
convert to an improper fraction
[tex]x=15\frac{5}{8}\ ft=\frac{15*8+5}{8}=\frac{125}{8}=15.625\ ft[/tex]
[tex]y=-10.2\ ft[/tex] -----> is negative because is below sea level
so
[tex]x-y=15.625-(-10.2)=15.625+10.2=25.825\ ft[/tex]
Remember that -1*(-1)=+1

Solving
64 + -12w = 6w
Solving for variable 'w'.
Move all terms containing w to the left, all other terms to the right.
Add '-6w' to each side of the equation.
64 + -12w + -6w = 6w + -6w
Combine like terms: -12w + -6w = -18w
64 + -18w = 6w + -6w
Combine like terms: 6w + -6w = 0
64 + -18w = 0
Add '-64' to each side of the equation.
64 + -64 + -18w = 0 + -64
Combine like terms: 64 + -64 = 0
0 + -18w = 0 + -64
-18w = 0 + -64
Combine like terms: 0 + -64 = -64
-18w = -64
Divide each side by '-18'.
w = 3.555555556
Simplifying

Jillian owns 60% of the stock
in a private catering
corporation. There are 1,200
shares in the entire
corporation. How many
shares does Jillian own?
Answer:
720 shares
Step-by-step explanation:
Find 60% of 1,200, to figure out how many shares Jillian has.
Change 60% to decimal
0.6
Multiply with the total shares
0.6 x 1,200 = 720
720 shares
Jillian owns 720 shares in a catering corporation.
What is the percentage?The percentage is defined as a ratio expressed as a fraction of 100.
What are Arithmetic operations?Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions.
The operator that performs the arithmetic operation is called the arithmetic operator.
+ Addition operation: Adds values on either side of the operator.
For example 4 + 2 = 6
- Subtraction operation: Subtracts the right-hand operand from the left-hand operand.
for example 4 -2 = 2
* Multiplication operation: Multiplies values on either side of the operator
For example 4*2 = 8
We have to determine 60% of 1,200, to figure out how many shares Jillian has.
Convert 60% into a decimal
⇒ 0.6
Multiply with the total shares
⇒ 0.6 × 1200
⇒ 720
Hence, Jillian owns 720 shares in a private catering corporation.

Enter the correct answer.
Answer:
Vertex of parabola (-1, -10)

Step-by-step explanation:
!. lan wants to promote his band on the Internet. Site A offers website
hosting for $4.95 per month with a $49.95 startup fee. Site B offers
website hosting for $9.95 per month with no startup fee. For how
many months would lan need to keep the website for Site B to be less
expensive than Site A?
Answer:
Ian need to keep the website for site B less than 10 months
Step-by-step explanation:
Let
x -----> the number of months
y ----> the cost for website hosting
we know that
Site A
[tex]y=4.95x+49.95[/tex] -----> equation A
Site B
[tex]y=9.95x[/tex] -----> equation B
Equate equation A and equation B and solve for x
[tex]9.95x=4.95x+49.95[/tex]
[tex]9.95x-4.95x=49.95[/tex]
[tex]5x=49.95[/tex]
[tex]x=9.99\ months[/tex]
Round the number of months
[tex]x=10\ months[/tex]
For x=10 months ----> the cost for website hosting is the same in both sites
For x>10 months ---> the cost for website hosting is less expensive in site A
For x<10 months ---> the cost for website hosting is less expensive in site B
therefore
Ian need to keep the website for site B less than 10 months
When comparing the two hosting sites, Site B becomes cheaper than Site A after around 10 months, if the website is kept active during this period. This calculation is made by setting up an equation for the costs and solving for the number of months.
Explanation:When Ian wants to promote his band on the Internet by creating a website, he needs to make a decision about the cost effectiveness between the two hosting sites. Let's break down the costs for each site:
Site A = $49.95 (startup fee) + $4.95 (per month fee)Site B = $9.95 (per month fee) as there is not a startup fee.To find out when Site B would be cheaper than Site A, we need to set up an equation where the left-hand side is the cost for Site A and the right-hand side is the cost for Site B. The equation would therefore be, $49.95 + $4.95n (with n being the number of months) = $9.95n.
To solve for n, subtract $4.95n from both sides leaving $49.95 = $5n. Dividing $49.95 by $5 gives us n = 9.99, which means after around 10 months, Site B becomes cheaper than Site A provided Ian keeps the site active.

in 3 equal piles, she also ended up with one extra bill. Frustrated, they tried 4
5, and 6 equal piles and each time had $1 left over. Finally Rowena put all the
bills evenly into 7 equal piles, and none were left over.
Based on this information, Ms. Speedi is sure there is enough money for the
fieldtrip!
a. What is the least amount of money they could have raised? Show how
know.
b.
It turns out that they raised more than $500. Knowing this, what is the least
amount of money they could have raised?
Answer:
A. $301
B. $721
Step-by-step explanation:
Let $x be the amount of money they raised.
Rowena tried to put the $1 bills into two equal piles and found one left over at the end, then
[tex]x=2q_1+1[/tex]
Polly tried to put the $1 bills into three equal piles and found one left over at the end, then
[tex]x=3q_2+1[/tex]
Frustrated, they tried 4, 5, and 6 equal piles and each time had $1 left over, then
[tex]x=4q_3+1\\ \\x=5q_4+1\\ \\x=6q_5+1[/tex]
Finally Rowena put all the bills evenly into 7 equal piles, and none were left over, then
[tex]x=7q_6[/tex]
This means [tex]x-1[/tex] is divisible by 2, 3, 4, 5 and 6 without remainder, so
[tex]x-1=2\cdot 3\cdot 2\cdot 5n=60n[/tex]
Hence,
[tex]x=60n+1, \ n\in N[/tex]
The smallest amount of money they could have raised is $301, because
[tex]x=60\cdot 5+1=301[/tex] is divisible by 7.
Now, the number [tex]x=60n+1[/tex] should be divisible by 7 and must be greater than 500.
So,
[tex]60n+1>500\\ \\60n>499\\ \\n>8[/tex]
When n = 9,
[tex]x=60\cdot 9+1=541[/tex] is not divisible by 7.
When n = 10,
[tex]x=60\cdot 10+1=601[/tex] is not divisible by 7.
When n = 11,
[tex]x=60\cdot 11+1=661[/tex] is not divisible by 7.
When n = 12,
[tex]x=60\cdot 12+1=721[/tex] is divisible by 7.
B. The least amount of money they could have raised is $721
Answer:
A:301 and b: 721
