The text of the question is incomplete. However, the likely question that can be asked may imply that; "what number of corn package did she use?"
Given that
1 package of corn = 8 cups
1 serving = 1 cup
Total individual = 11
Servings per individual = 2
If there are 2 servings per individual then 1 package of corn will serve the following number of people.
1 package of corn = 8 / 2 individuals
1 package of corn = 4 individuals
Divide both sides by 4.
1 package of corn / 4 = 4 individuals / 4
¼ package of corn = 1 individual.
Re-arrange
1 individual = ¼ package of corn.
So, this means that 11 individuals will get;
[Multiply both sides by 11]
11 * 1 individual = ¼ * 11 package of corn
11 individuals = 11/4 package of corn
11 individuals = 2.75 packages of corn.
Hence, Ron will need 2.75 packages of corn for 11 individuals
A child's sandbox is 5 feet wide, 4 feet long, and 3 feet deep. Grace fills the sandbox so that the sand is 2 ½ feet deep. What is the volume of the sand in the box?
Answer:
the volume of sand is [tex]50 ft^{3}[/tex]
Step-by-step explanation:
This problem bothers on the mensuration of solid shapes, rectangular prism.
Given data
[tex]Length l= 4 ft Width w= 5ft\\Height h = 3ft[/tex]
if the sandbox is filled with sand of [tex]2\frac{1}{2 } ft[/tex] deep the volume of the sand in the box will be calculated based on the the depth of the sand
converting the depth of sand from mixed fraction to proper fraction we have [tex]2\frac{1}{2} = \frac{5}{2}[/tex]
the expression for the volume of a rectangular prism is
[tex]volume of sand = length * width* height[/tex]
substituting our data into the expression we have
[tex]volume of sand= 5*4 * \frac{5}{2} \\volume of sand = \frac{100}{2} \\volume of sand = 50 ft^{3}[/tex]

You flip a coin twice.
What is the probability of getting tails and then getting heads?
Write your answer as a percentage.
___%
Your answer would be 25%.
Assuming the coin is not biased, the probability of flipping a heads or tails is 1/2 equally. This remains the same no matter how many times you flip the coin, because the outcome of one flip does not affect the outcome of another.
This means that the probability of getting a tails the first flip is 1/2, and the probability of then getting a heads is also 1/2, so to find the probability of both happening you need to multiply these probabilities together, and 1/2 × 1/2 = 1/4, and 1/4 as a percentage is 25%.
I hope this helps! Let me know if you have any questions :)
how would you solve 4x - 3y = 78 2x + 3y = 48 by elimination
Answer:
x = 21, y = 2
Step-by-step explanation:
4x- 3y = 78....(1)
2x + 3y = 48 ...(2)
Adding eqiautions (1) and (2)
4x- 3y = 78
2x + 3y = 48
-----------------------
6x + 0 = 126....(Here y has been eliminated)
6x = 126
[tex] x= \frac{126}{6}\\\\
\therefore x = 21\\[/tex]
Plugging x = 21 in equation (2) we find:
2 * 21 + 3y = 48
42 + 3y = 48
3y = 48 - 42
3y = 6
[tex] y= \frac{6}{3}\\\\
\therefore y = 2\\[/tex]

Answer:
1st option.
[tex]\sum_{k=1}^{6} \frac{1}{2k-1}[/tex]
Step-by-step explanation:
The given sequence is as follows:
[tex]1 + \dfrac{1}{3}+ \dfrac{1}{5}+ \dfrac{1}{7}+ \dfrac{1}{9}+ \dfrac{1}{11}[/tex]
Here, we can see that the denominator is in AP and the sequence is:
1, 3, 7, 9, 11
first term, a = 1
Common difference, d = 2
We know that nth term for an AP:
[tex]a_n = a+(n-1)d[/tex]
where a is the first term and
d is the common difference.
So, nth term for above AP:
[tex]a_n = 1+(n-1)\times 2\\\Rightarrow 2n-1[/tex]
Here, we have 'k' in place of 'n':
[tex]a_k = 2k-1[/tex]
And as per the given sequence in the question, the kth term is simply the reciprocal:
i.e. [tex]\dfrac{1}{2k-1}[/tex]
and sum is to be done up to k = 6 from k = 1.
Hence, the summation notation for the sequence
[tex]1 + \dfrac{1}{3}+ \dfrac{1}{5}+ \dfrac{1}{7}+ \dfrac{1}{9}+ \dfrac{1}{11}[/tex]
is:
[tex]\sum_{k=1}^{6} \frac{1}{2k-1}[/tex]

Square root of 8.8 up to two decimal step by step explanation
Answer:
2.97
Step-by-step explanation:
8.8 = 4 *2.2 = 4 * 220/100
220 = 4 *55
8.8 = (4 *4*55)/100 = 16 *55/100
[tex]\sqrt{8.8} =\sqrt{(16 * 55)}/\sqrt{100\\}[/tex]
[tex]\sqrt{8.8}= \frac{4}{10}*\sqrt{55}[/tex]

Answer:
A(x) = 6.2 - 0.005x
Step-by-step explanation:
If you think about it, either 0.5/0.005 needs to be equal to 0.5%
0.5 is the same as 1/2 and therefore it is the same as 50%
So it must be 0.005!
Tip: I always just divide by 100 to get the decimal, it is a nice, easy and quick method
A boat travels upstream for 96 miles in 4 hours and returns in 3 hours traveling downstream in a river. What is the rate of the boat in still water and what is the rate of the current?
Answer:
Speed of boat in still water = 28 miles/hr
Speed of current = 4 miles/hr
Step-by-step explanation:
Speed upstream, u = 96/4 = 24 miles/hr
Speed downstream, v = 96/3 = 32 miles/hr
Speed of boat in still water = ½(v+u)
= ½ (24 + 32) = 28 miles/hr
Speed of the current = ½ ( v - u)
= ½ (32 - 24) = 4 miles/hr

x^2 + x - 42
Answer:
x = 6 or x = -7
Step-by-step explanation:
Solve for x over the real numbers:
x^2 + x - 42 = 0
The left hand side factors into a product with two terms:
(x - 6) (x + 7) = 0
Split into two equations:
x - 6 = 0 or x + 7 = 0
Add 6 to both sides:
x = 6 or x + 7 = 0
Subtract 7 from both sides:
Answer: x = 6 or x = -7

b
Step-by-step explanation:
3 + 4x < 2(1 + 2x)
3 + 4x < 2 + 4x
Answer: the second answer
Step-by-step explanation:
If we want to find an inequality with no solution, that means we can expect no x and an unbalanced inequality (e.g., 3<0 which is untrue).
The second one is like that because the inequality is
3+4x[tex]\leq[/tex]2(1+2x)
If we solve it out, we get
3+4x[tex]\leq[/tex]2+4x
When you remove the variable from both sides, you now have
3[tex]\leq[/tex]2
This statement is false, since 2 will never be greater than 3.
If we look at the others, we can see that there are answers for all of them.

In parallelogram DEFG, DH = x + 2, HF = 2y, GH = 4x – 3, and HE = 5y + 1. Find the values of x and y.
Answer: x = 6, y = 4
Step-by-step explanation:
Given the following :
In parallelogram DEFG:
DH = x + 2, HF = 2y, GH = 4x – 3, and HE = 5y + 1
According to the diagram,
The diagonals of the parallelogram buscect each other
The diagonal GE:
GH = HE
4x - 3 = 5y + 1 - - - - (1)
The Diagonal DF:
DH = HF
x + 2 = 2y
x = 2y - 2 - - - - - (2)
Replace x = 2y - 2 in equation (1)
4(2y - 2) - 3 = 5y + 1
8y - 8 - 3 = 5y + 1
8y - 5y = 1 + 8 + 3
3y = 12
y = 4
Substityte y = 4 in equation (2)
x = 2(4) - 2
x = 8 - 2
x = 6
x = 6, y = 4

Simon took out a zero-interest loan for $3,300 to buy a boat. He must pay $300 per month to pay off the total balance of the boat's purchase price. Simon also has $1,000 in his savings account. He plans to deposit $600 every month in this account. So, Simon would like a system of equations that tells him at what point he will be able to pay off the total balance for the boat with the help of his savings. Write the second equation in the system. Enter the correct answer in the box. Substitute numerical values into the expression for all known variables.
Answer:
After 3 months, Simon will be able to pay off his loan with the money he holds at his savings account.
Step-by-step explanation:
ending loan's principal balance = beginning loan's principal balance - number of months x $300
or we can simplify it: l₁ = l₀ - 300x ⇒ l₁ = 3,300 - 300x
l₁ = ending loan's principal balance
x = number of months
ending savings account balance = beginning savings account balance + number of months x $600
or we can simplify it: s₁ = s₀ + 600x ⇒ s₁ = 1,000 + 600x
s₁ = ending savings account balance
x = number of months
account balances for months
month 1 month 2 month 3 month 4
boat loan $3.000 $2,700 $2,400 $2,100
savings account $1,600 $2,200 $2,800 $3,400
Answer:
y equals 300x plus 3300

the sign has a diameter of 30 inches what is the circumference use 3.14 for pie
Answer:
94.2 inches.
Step-by-step explanation:
First, I just want to clarify that [tex]\pi[/tex] is actually spelled pi, not pie, like the pie you eat.
Finding the circumference is pretty easy. It is just the diameter times pi.
So if the diameter is 30 inches, and we use 3.14 for pi, then the circumference of the sign would be 94.2 inches.
Hope this helps!
