Answers
The three negative effects of aggregates containing excessive amounts of very fine materials are Reduced workability, Increased water demand, Decreased strength and durability.
To mitigate these negative effects, proper grading and selection of aggregates is important. Using well-graded aggregates with a suitable proportion of coarse and fine materials can improve workability and reduce the negative impacts on concrete strength and durability.
The negative effects of aggregates containing excessive amounts of very fine materials, such as clay and silt, in concrete can include:
1. Reduced workability: Excessive amounts of clay and silt can lead to a sticky and cohesive mixture, making it difficult to work with. This can result in poor compaction and uneven distribution of aggregates, affecting the overall strength and durability of the concrete.
2. Increased water demand: Fine materials tend to absorb more water, which can lead to an increase in the water-cement ratio. This can compromise the strength of the concrete and result in a higher risk of cracking and reduced long-term durability.
3. Decreased strength and durability: Clay and silt particles have a larger surface area compared to coarse aggregates, which can lead to higher water absorption and a weaker bond between the aggregates and the cement paste. This can result in reduced strength and durability of the concrete over time.

Answers
option B accurately represents the relationship between the number of smoothies sold and the balance of the cash box, demonstrating the gradual increase in the cash box balance as Jackie sells more smoothies.
Option B is the correct answer.
We have,
The graph plots the number of smoothies sold (x) on the x-axis and the balance of the cash box (y) on the y-axis.
The points on the graph indicate specific values of x and y.
For example, at the starting point (0, 15), which represents zero smoothies sold, the cash box balance is $15.
As Jackie sells more smoothies, the balance increases gradually.
The diagonal curve in the graph indicates a linear relationship between the number of smoothies sold and the balance of the cash box.
Each time two smoothies are sold (x increases by 2), the balance of the cash box increases by $7.5 (y increases by 7.5).
This linear relationship is consistent throughout the graph, showing that as more smoothies are sold, the cash box balance increases in a predictable and proportional manner.
Therefore,
option B accurately represents the relationship between the number of smoothies sold and the balance of the cash box, demonstrating the gradual increase in the cash box balance as Jackie sells more smoothies.

Answers
Answer:
i say 24,890
Step-by-step explanation:
The number of stuffed animals did the toy store sell in 2014, 2015, and 2016 combined is 87,049.
Given that, in 2014, a toy store sold 12,823 stuffed animals. In 2015, the toy store sold 24,290 more stuffed animals than it did in 2014.
What is an equation?In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
Let the number of stuffed animals did the toy store sell in 2014, 2015, and 2016 combined be x.
Number of toys sold in 2014 = 12,823
Number of toys sold in 2015 = 12,823 + 24,290
=37,113
The toy store sold the same number of stuffed animals in 2016 as it did in 2015. That is, 37,113.
Now, x = Number of toys sold in 2014 + Number of toys sold in 2015 + Number of toys sold in 2016
=12,823+37,113+37,113
=87,049
Therefore, the number of stuffed animals did the toy store sell in 2014, 2015, and 2016 combined is 87,049.

Find (x) given that ′ (x) = 10x^4 − 12x^3 + 8^−4x + 7 and
(0) = −9. Show All Work.
Answers
The value of y at x = 0 is -9/7 for the given differential equation y' = 10x⁴ − 12x³ + 8⁻⁴ˣ + 7 . Therefore, option C is correct.
Given the differential equation y' = 10x⁴ − 12x³ + 8⁻⁴ˣ + 7 and (0) = −9,
we are to find the value of y at x = 0.
The given differential equation is,
y' = 10x⁴ − 12x³ + 8⁻⁴ˣ + 7
It is in the form y' = f(x)
Now, we integrate the given differential equation with respect to x,
∫y' dx = ∫(y' = 10x⁴ − 12x³ + 8⁻⁴ˣ + 7) dx
Integrating the right hand side w.r.t x, we get
y = 10x⁵/5 − 12x⁴/4 + 8⁻⁴ˣ²/2 + 7x + c
where c is the constant of integration.
Now, we have (0) = −9 i.e. y = -9 when x = 0.
Substituting the values of x and y, we have
-9 = 0 + 0 + 0 + 7c
Therefore,
c = (-9 - 0 - 0)/7
= -9/7
Hence, the value of c is -9/7
Putting the value of c in the equation of y, we have
y = 2x⁵ - 3x⁴ + 4x² - 9/7
The value of y at x = 0 is
y = 0 - 0 + 0 - 9/7
= -9/7.
Therefore, option C is correct.

The z score associated with the highest 10% is closest to: option (c) 1.28
-To find the z score associated with the highest 10%, first determine the percentage that corresponds to the lower 90%, since the z score table typically represents the area to the left of the z score.
- Look up the 0.90 (90%) in a standard normal distribution (z score) table, which will give you the corresponding z score.
-The z score closest to 0.90 in the table is 1.28, which corresponds to the highest 10% of values.
Therefore, the z score associated with the highest 10% is closest to 1.28.

In may, seattle's daily high temperature has a mean of f and a standard deviation of f. the formula to convert degrees fahrenheit f to degrees celsius c is:_____.
Answers
The answer is : C = (F - 32) * 5/9.
To convert degrees Fahrenheit (F) to degrees Celsius (C), you can use the following formula:
C = (F - 32) * (5/9)
This formula is a commonly used conversion equation in which you subtract 32 from the temperature in Fahrenheit and then multiply the result by 5/9 to obtain the equivalent temperature in Celsius.
Let's break down the formula to understand how it works. Starting with the Fahrenheit temperature (F), subtracting 32 adjusts the temperature relative to the freezing point of water in Fahrenheit (32°F). This step ensures that 0°F in Celsius is equivalent to -17.78°C, which is the freezing point of water in Celsius.
After subtracting 32, we multiply the result by 5/9. This step converts the adjusted Fahrenheit temperature into the equivalent Celsius temperature. The multiplication by 5/9 accounts for the ratio of the size of a degree Fahrenheit to the size of a degree Celsius.
By using this formula, you can convert any temperature from Fahrenheit to Celsius. For example, if the mean daily high temperature in Seattle in May is represented by f, you can substitute that value into the formula to calculate the mean temperature in Celsius.

A rectangle is 3 cm longer than it is wide. The diagonal is 15 cm. Find the dimensions of the rectangle?
Answers
Answer:
The length is 12 cm, and the width is 9 cm.
Step-by-step explanation:
The length and width of a rectangle as legs form a right triangle with the diagonal of the triangle as the hypotenuse.
We can use the Pythagorean theorem to write an equation.
Let the width = w = leg a
The length = w + 3 = leg b
The diagonal = the hypotenuse = 12 = c
a^2 + b^2 = c^2
w^2 + (w + 3)^2 = 15^2
w^2 + w^2 + 6w + 9 = 225
2w^2 + 6w - 216 = 0
w^2 + 3w - 108 = 0
(w + 12)(w - 9) = 0
w + 12 = 0 or w - 9 = 0
w = -12 or w = 9
Since a width cannot be a negative number, we discard the solution w = -12.
width = w = 9
length = w + 3 = 9 + 3 = 12
Answer: The length is 12 cm, and the width is 9 cm.

For example, if your answer is 4/15 + 6/15, leave it in that form or you could write it as 10/15 or 2/3 but don't write it as a decimal. Use to indicate multiplication and to indicate raising a number to a certain power. (eg. (4/15)^2 means 4/15*4/15) 1. Suppose you randomly selected one juice box from the cooler. What is the chance that the juice box is either red or green?
Answers
The probability of selecting a juice box that is either red or green is 7/15 or about 0.47.
There are a total of 15 juice boxes in the cooler, 5 of which are red and 2 of which are green. Therefore, the probability of selecting a red juice box is 5/15, or 1/3, and the probability of selecting a green juice box is 2/15.
To find the probability of selecting either a red or a green juice box, we can add the individual probabilities of selecting a red juice box and a green juice box.
P(selecting a red or a green juice box) = P(selecting a red juice box) + P(selecting a green juice box)
= 5/15 + 2/15
= 7/15
This means that out of every 15 juice boxes selected at random, approximately 7 will be either red or green.

The Length of AD is 78 cm.
From the figure, G is Centroid.
The point in which the three medians of the triangle intersect is known as the centroid of a triangle.
It is also defined as the point of intersection of all the three medians. The median is a line that joins the midpoint of a side and the opposite vertex of the triangle.
The centroid of the triangle separates the median in the ratio of 2: 1.
Centroid divides median in the ratio 2:1 .
