The cost of one ounce of cereal is $0.23
Given:
Amount of cereals a box contain = 24 ounces
Cost of one box = $5.52
Cost of cereal per ounce = Cost of cereal / Amount of cereals in a box
Cost of cereal per ounce = $5.52 / 24
Cost of cereal per ounce = $0.23
What is Ounce ?An ounce is any of various units of mass, weight or volume derived almost invariably from the ancient Roman unit of measure, the ounce. an avoirdupois ounce is 1⁄16 avoirdupois pound; it is the US and British imperial ounce. 1 ounce is equal to 437.5 grains or 28.349 grams, A US customary fluid ounce is 1⁄16 of a US liquid pint and 1⁄128 of a US liquid gallon or exactly 29.5735295625 mL.

The sum of a number and its half is thirty. Find the number
Answer:
20
Step-by-step explanation:
The sum of a number and its half is thirty. Find the number:
the formula would be:
1.5x = 30
divide both sides by 1.5:
1.5x/1.5 = 30/1.5
x = 20
check:
20 = 20
1/2 of 20 = 10
20 + 10 = 30
Answer:
x+0.5x=30
1.5x=30
x=20

The number line (C) represents the solution to the inequality -0.96 ≥ 0.3x option (C) is correct.
What is inequality?It is defined as the expression in mathematics in which both sides are not equal they have mathematical signs either less than or greater than known as inequality.
The inequality is:
Let the number is x:
-0.96 ≥ 0.3x
0.3x ≤ -0.96
x ≤ -0.96 /0.3
x ≤ -3.2
x ∈ (-∞, -3.2]
As we know, the number line can be defined as the representation of the numbers on a straight line that goes infinitely on both sides.
The number line (C) represents the solution to the inequality -0.96 ≥ 0.3x
Thus, the number line (C) represents the solution to the inequality -0.96 ≥ 0.3x option (C) is correct.

Solve the following system of equations
2x -9y = -1
-4x -3y = -19
(See picture attached)
Solution :-
2x - 9y = -1
2x = 9y - 1
x = 9y - 1 / 2 _________ (1)
Now, substitute it here!
-4x - 3y = - 19
-4 (9y - 1 /2) - 3y = -19
(-36y + 4 - 6y / 2) = -19
(-42y + 4 / 2) = -19
-42y + 4 = -38
-42y = -38 - 4
-42y = -42
y = 1
Value of x :
Substituting the value of y that is 1 in this equation. x = 9y - 1 / 2
x = 9(1) - 1 / 2
x = 9 - 1 / 2
x = 8 / 2
x = 4
four minus 7 times a number is equal to 12 minus 3 times the number
Answer:
number is - 2
Step-by-step explanation:
let the number be n then 7 times the number is 7n and 3 times the number is 3n, so
4 - 7n = 12 - 3n ( add 3n to both sides )
4 - 4n = 12 ( subtract 4 from both sides )
- 4n = 8 ( divide both sides by - 4 )
n = - 2

If a store advertised a sale that gave customers a 1/4 off the original price of $825.00 he also wanted to use a coupon for 1/5?of the sales price . How much did he pay ?
If a store advertised a sale that gave customers a 1/4 off the original price of $825.00 he also wanted to use a coupon for 1/5 off the sale price, then he paid $453.75
The original price of the item = $825
The off offered by the store = 1/4
The off offered by the coupon = 1/5
Total off = 1/4 + 1/5
= 9/20
Then the selling price = The original price of the item - The original price of the item× (9/20)
= 825 - 825×9/20
= 825-371.25
= $453.75
Hence, if a store advertised a sale that gave customers a 1/4 off the original price of $825.00 he also wanted to use a coupon for 1/5 off the sale price, then he paid $453.75

which critical value is appropriate for a 99% confidence level where n17, is unknown, and the population appears to be normally distributed? question content area bottom part 1 a. 2.567 b. 2.921 c. 2.898 d. 2.583
The critical value that is appropriate for a 99% confidence level where n17, is unknown, and the population appears to be normally distributed is 2.921 (Option B).
What is the Critical Value in statistics?A Critical value is the value of the test statistic that establishes the upper and lower boundaries of a confidence interval or the statistical significance threshold in a statistical test.
How did we arrive at the above conclusion?
We are given:
n=17, where n is the size of the set
df = n-1; (df means degree of freedom)
= 17-1
df = 16, at 99% confidence level.
Here we apply the t-test because the data is normally distributed.
∝ = 1-99% [Shere ∝ is the significance level)
= 0.01
∝/2 = 0.01/2
= 0.005
hence,
[tex]t_{\alpha /2} ,df[/tex] = [tex]t_{0.005}[/tex], 16 = 2.921. this is derived using the T-Table.
The above leads us to conclude therefore that Option B is correct.

A package falls from an airplane and hits there ground 12 seconds later. How high was the airplane flying?
The plane was flying at a height of 706.32 m .
The fundamentals of an object's motion, such as its position, velocity, or acceleration over time, are defined by kinematics equations of motion. An object's motion in one, two, and three dimensions is determined by these three equations of motion. One of three equations of motion can be used to calculate components like displacement (s), velocity (initial and final), time (t), and acceleration (a). The following are the three motion equations:
Initial formula: v = u + at
The second formula is s = ut + 0.5at2.
The third formula is v2 = u2 + 2as.
Let t stand for the package's flight time, s for the plane's altitude, and u for the packet's initial vertical velocity since it is simply dropped.
Given: t = 12 seconds for the delivery to arrive to the ground
With t = 12 and u = 0 in the second equation of motion, we so obtain
s = 0*t + 0.5*9.81*12² = 706.32 m

The values of x and y in the system of equations are x = 1 and y = 2
What are linear equations?Linear equations are equations that have constant average rates of change.
How to determine the solution to the system?A system of linear equations is a collection of at least two linear equations.
In this case, the system of equations is given as
4x + 3y = 10
y - x = 1
Make y the subject in the second equation, by adding x to both sides of the equation
y - x + x = x + 1
This gives
y = x + 1
Substitute y = x + 1 in 4x + 3y = 10
4x + 3(x + 1) = 10
4x + 3x + 3 = 10
Evaluate the like terms
7x = 7
This gives
x = 1
Substitute x = 1 in y = x + 1
y = 1 + 1
Evaluate
y = 2
Hence, the solution for the system of linear equations 4x + 3y = 10 and y - x = 1 are x = 1 and y = 2

your average score?
Hint: Find the mean of both sets of data. Then
find the difference between the two. Round to
the nearest %.
His grades improved by 2.2 %
What is mean?The sum of all values divided by the total number of values determines the mean (also known as the arithmetic mean, which differs from the geometric mean) of a dataset. The term "average" is frequently used to describe this measure of central tendency.
Given: Original grades = 75, 85, 90, 90,
100, 75, 80, 100, 90.
And grades after the retake = 85, 85, 100, 90, 100, 85, 80, 100, 90.
So the sum of the original scores = 785.
Thus the percentage can be calculated by 785/ total marks
= 785/ 900 × 100 = 87.2 %
And the sum of the grades after retake= 805
Thus the percentage will become = 805/900 × 100 = 89.4 %
The mean of the first set is 87 and the mean of the second set is 89.
Thus the difference between the two is 2.

The area of the rectangle will be 512[tex]cm^{2}[/tex] .
let the longer side of the rectangle be "l" and the shorter side of the rectangle be "b".
Hence, the perimeter of rectangle = 2(l+b)
we are given the perimeter =96cm
thus, 2(l+b)=96
l+b = 96/2
l+b =48
also, we are given the condition that the longer side of the rectangle is two times the length of the Shorter side.
Thus, l=2b, substituting this in l+b=48 we get
2b+b=48
3b=48
b=48/3
b=16cm, now substituting this in l=2b,
l=2(16)
l=32cm
area of the rectangle = length x breadth
