A box of cereal is halfway full. How much cereal is in the box? 14 in 2 in 8.8 in
Answer:
I'm honestly proud of myself for getting this right, the answer is 123.2
Step-by-step explanation:
14 x 8.8 x 2 divides by 2 and that's your answer pretty self-explanatory and simple
(2x2 + 2x + 3) - (x2 + 2x + 1) =
O A. x2 + 4
O B. x2 + 4x + 2
O C. x2 + 4x + 4
O D. x2 + 2
Answer:
\( \boxed{\sf D. \ x^2 + 2} \)
Step-by-step explanation:
\( \sf Simplify \ the \ following: \)
\( \sf \implies (2 {x}^{2} + 2x + 3) - ( {x}^{2} + 2x + 1)\)
\( \sf - ( {x}^{2} + 2x + 1) = - {x}^{2} - 2x - 1 : \)
\( \sf \implies (2 {x}^{2} + 2x + 3) - {x}^{2} - 2x - 1\)
\( \sf Grouping \ like \ terms: \)
\( \sf \implies (2 {x}^{2} - {x}^{2}) + (2x - 2x)+ (3 - 1)\)
\( \sf 2 {x}^{2} - {x}^{2} = {x}^{2} : \)
\( \sf \implies {x}^{2} + (2x - 2x)+ (3 - 1)\)
\( \sf 2x - 2x = 0 : \)
\( \sf \implies {x}^{2} + 0+ (3 - 1)\)
\( \sf 3 - 1 = 2 : \)
\( \sf \implies {x}^{2} +2\)

Answer:
10, 3,6,-1,3 respectively$100 are shared between Adam and Hamza in the ratio 1:3.
A)
How many dollars did Adam receive?
How many dollars did Hamza receive?
Answer:
$25 for Adam and $75 for Hamza
Step-by-step explanation:
$100 will be divided to 3 + 1 = 4 parts
the dollars Adam received
= $100 × 1/4
= $25
the dollars Hamza received
= $100 × 3/4
= $75
-----------------------------------------------------------
the dollars Hamza give to Adam
= $75 × 25%
= $75 × 25/100
= $18.75
the dollars Adam have
= $25 + $18.75
= $43.75
the dollars Hamza have
= $75 - $18.75
= $56.25
the ratio
= 43.75:56.25
= 7:9

Step-by-step explanation:
The first 4 digits are simple, you multiply the first digit of the equation by the 2nd digit and then for the other 2 you multiply the first digit of the equation by the 3rd digit.
6 + 2 + 8
6 * 2 = 12
6 * 8 = 48
Then the last 2 digits are the sum of the products of the 1 and 2 and 1 and 3 and subtract it by the 2
12 + 48 = 60
60 - 2 = 58

What is the slope of the line
represented by the equation
2y = 5x + 4?
Answer: The slope is 5/2.
Step-by-step explanation:
Convert the equation into slope intercept form, ( y=mx+b)
2y = 5x + 4 Divide each side by 2
y = 5/2x + 2 In this form the slope will be the coefficient of x variable.
The coefficient is the number that comes before x.
In this case, the slope is 5/2.

Find the length of QR
Answer:
QR = 15
Step-by-step explanation:
The product of the length of the secant segment and its external part equals the square of the length of the tangent segment.
(QR+5) *5 = 10^2
(QR+5) *5 = 100
Divide each side by 5.
(QR+5) *5/5 = 100/5
(QR+5) = 20
Subtract 5 from each side.
QR = 20-5

You number each subject in the population. Then place numbered cards in a bowl, mix them thoroughly, and select as many cards as needed. This is an example of which sampling method? ç”æ¡ˆé€‰é¡¹ç»„ Random Sampling Stratified Sampling Cluster Sampling Systematic Sampling
The described sampling method is an example of random sampling.
The sampling method described in the question is known as simple random sampling, which is a common method of selecting a representative sample from a population.
In this method, each member of the population is assigned a unique number, and a certain number of individuals are selected randomly from the population.
Simple random sampling is a type of probability sampling, which means that each member of the population has an equal chance of being selected for the sample.
This is important because it ensures that the sample is representative of the population as a whole, and reduces the risk of sampling bias.
The process of simple random sampling is straightforward and easy to implement, making it a popular choice for researchers. However, it can be time-consuming and may not be practical for very large populations. In such cases, other sampling methods such as stratified sampling or cluster sampling may be more appropriate.
Overall, simple random sampling is a reliable and effective method of selecting a representative sample from a population, and is widely used in research studies and surveys.

choose the expression that best completes this sentence: the function f(x) = ________________ has a local minimum at the point (8,0). a) x−8 b) (x−8)−1 c) x2−16x 64 d) −|x−8| e) (x−8)13
The correct answer to this question is option C: f(x) =\(x^2 - 16x + 64\). This is because the expression \(x^2 - 16x + 64\) can be factored as\((x - 8)^2,\) which represents a parabola that opens upwards and has its vertex at the point (8, 0).
The fact that the vertex is a minimum point can be seen by observing that the coefficient of \(x^2\) is positive, which means that the parabola opens upwards. In addition, the squared term in the expression \((x - 8)^2\)ensures that the function is symmetric around x = 8, which means that the vertex is the lowest point on the curve within some neighborhood of x = 8. Therefore, the function f(x) = \(x^2 - 16x + 64\)has a local minimum at the point (8,0).

A granola bite contains 27 calories. Most of the calories come from grams of carbohydrates. The rest come from other
ingredients. One gram of carbohydrate contains 4 calories.
The equation 4c + 5 = 27 represents the relationship between these quantities.
1. What could the 5 represent in this situation?
2. Priya said that neither 8 nor 3 could be the solution to the equation. Explain why she is correct.
3. Find the solution to the equation.
Answer:
Step-by-step explanation:
Total calories in a granola bite= 27
The calories contained are from grams of carbohydrates and other ingredients
One gram of carbohydrate contains 4 calories
The equation 4c + 5 = 27 represents the relationship between these quantities.
1. 5 from the equation represent calories from other ingredients
2. Neither 8 nor 3 is the solution to the equation
4c + 5 = 27
When 8 is the solution
4(8)+5=27
32+5=27
37=27
When 3 is the solution
4(3)+5=27
12+5=27
17=27
Neither 8 nor 3 is the solution to the equation because 8 gives a higher calories in the granola bite and 3 gives a lower calories in the granola bite.
3. Solution to the equation
4c + 5 = 27
4c= 27-5
4c = 22
Divide both sides by 4
c=22/4
=5 2/4
=5 1/2
The solution to the equation is 5 1/2

The volume of the soup pot is approximately 429.6 cubic inches.
The volume of a cylinder (like the soup pot) can be calculated using the formula:
V = πr²h
where:
V = volume
π = 3.14159 (approximate value of pi)
r = radius
h = height
Substituting the given values, we get:
V = π*(4²)*(8.5)
V = 3.14159*(16)*(8.5)
V = 429.58124
Rounding to the nearest tenth, the volume of the soup pot is approximately 429.6 cubic inches.

The long hand of the clock is about 5 inches long. How far does the end of the long hand of the clock travel in 2 1/2 hours?
The end of the long hand of the clock travels about 78.54 inches (25π) in 2 1/2 hours.
What is clock ?
Clock can be defined as a machine in which a device that performs regular movements in equal intervals of time is linked to a counting mechanism that records the number of movements
The long hand of the clock completes one full revolution in 12 hours. Therefore, in one hour, it travels a distance equal to the circumference of a circle with a radius of 5 inches, which is given by 2πr = 2π(5) = 10π inches.
In 2 1/2 hours, the long hand of the clock travels a distance equal to (2 1/2) x 10π = 25π inches.
So, the end of the long hand of the clock travels about 78.54 inches (25π) in 2 1/2 hours.
