Agnes, evangelina, isabela, omar, and yuri each made a tower using wooden blocks. each person used a different number of blocks in their tower, and the mean (average) number of blocks in each tower was 25 . yuri used the most blocks in her tower, and agnes used the fewest blocks in her tower. if yuri used 32 blocks, determine the minimum possible number of blocks that agnes could have used.
Given a block play problem, the minimum number of blocks Agnes can use to build a tower is 3 or 1.
To calculate the average (mean) of a set of values, first divide by the number of values in the set. Therefore, the sum of the values in the set is equal to their average multiplied by the number of values in the set. The average number of blocks in each tower was 25, and since there were 5 towers, the total number of blocks used was 5 × 25 = 125. Yuri's Tower used 32 blocks, so the remaining towers used a total of 125 minus 32 = 93 blocks.
To find the minimum possible number of blocks for Agne's tower, let the other three towers use as many blocks as possible. Now we know that Yuri's tower used the most blocks and each tower used a different number of blocks. So the other 3 towers can use up to 31, 30 and 29 blocks respectively. The result was an absolute minimum number of blocks that Agnes could use, 93 - 31 - 30 - 29 = 3
By the way, the minimum number of blocks Agnes can use is not 93 - 32 - 32 - 32 = - 3 , but negative value is not possible. so, if everyone could use the same number of blocks. Agnes must have used at least one block, as it is possible to use a negative number of blocks.

Solve for the single variable in the equation below:
−16+x=−27
Answer:
x = -11
Step-by-step explanation:
Hello!
This is a one-step equation. To solve for x, you simply have to isolate it.
Since -16 is being added to x, we can add 16 to both sides to cancel out the negative 16.
Solve for x-16 + x = -27-16 + x + 16 = -27 + 16x = -11The value of x is -11.
In a given year, residents of a country spent approximately $52.9 billion on their pets. Of this amount, $17.3 billion was for veterinarian bills. What percent of the total was spent on veterinary cave?About ...% of the total was spent on veterinary care.
32.7 %
Explanation
we can easily solve this by using a rule of three
Step 1
Let x represents the percent of the total that was spent on veterinary
[tex]\begin{gathered} \text{ \$ 52.9 billions}\rightarrow100\text{ percent} \\ \text{ \$ 17.3 billons}\rightarrow x\text{ percent} \end{gathered}[/tex]
the ratios are equal , so we have a proportion
[tex]\frac{52.9}{100}=\frac{17.3}{x}[/tex]Step 2
solve the equation
[tex]\begin{gathered} \frac{52.9}{100}=\frac{17.3}{x} \\ \text{cross multiply} \\ 52.9x\cdot17.3\cdot100 \\ 52.9x=1730 \\ \text{divide both sides by 52.9} \\ \frac{52.9x}{52.9}=\frac{1730}{52.9}=32.7 \\ x=32.7 \\ \\ \end{gathered}[/tex]so, the answer is
About 32.7% of the total was spent on veterinary care.

a. Write an inequality for this situation. Let x represent
the number of weeks she withdraws money from her
account.
b. What is the maximum whole number of weeks
that Olivia can withdraw money from her account?
Explain how you know your answer is correct.
a. The amount remaining in the account after x week is 700 - 40x
b. Olivia can withdraw can withdraw money from her account money for approx. 13 weeks.
Let x represent the number of weeks. Then the amount of withdrawal in this time is 40x
So, the amount remaining in the account after x weeks is 700 - 40x
Since he needs 150$ in the account for safety net, we must have
700 – 40x ≥ 150
So,
700 - 150 ≥ 40x
550 ≥ 40x
550/40 ≥ x
x ≤ 13.75
Hence, he can withdraw money for approx. 13 weeks.

. of the 27 tasks available, 3 will pay $1000, 5 will pay $500, 10 will pay $200, and 9 will pay $100. you are assigned two tasks. what is the probability that you will make at least $1300?
The probability that you will make at least $1300 is 2/39 or 0.0513.
Probability is defined as the likeliness of an event to occur. The probability of any event to occur ranges from 0 to 1, and the sum of all the probabilities of all the events happening is 1.
probability = desired outcome / total outcomes
Using combinations, if there are 27 tasks available, then there are 351 combinations of two tasks assigned.
27C2 = 351
Also, count how many ways you could make at least $1300.
# ways = 2 of $1000 each or 1 of $1000 and 1 of $500
# ways = (3C2) + (3 x 5)
# ways = 3 + 15
# ways = 18
Solve for the probability by dividing the number of the desired outcomes by the number of total possible outcomes.
probability = desired outcome / total outcomes
probability = 18 / 351
probability = 2/39 or 0.0513

an instructor has graded 22 exam papers submitted by students in a class of 23 students, and the average so far is 73. how high would the score on the last paper have to be to raise the class average by 1 point?
The next score have to be 96 to raise the class average by 1 point.
Explanation :
Let the score of the last paper be x, then
(22(73) + x)/23 = 74
22(73) + x = 74 x 23
1606+ x = 1702
x = 1702- 1606 = 96
x = 96
The next score have to be 96 to raise the class average by 1 point.
Solution in math :
An assignment of values to the unknown variables that establishes the equality in the equation is referred to as a solution. To put it another way, a solution is a value or set of values that, when used to replace the unknowns, cause the equation to equal itself. You can solve an equation numerically or symbolically.When an equation is solved numerically, only numbers are accepted as solutions. When an equation is solved symbolically, the solutions can be represented by expressions. The distinction between known variables and unknown variables is generally made in the statement of the problem, by phrases such as "an equation in x and y", or "solve for x and y", which indicate the unknowns, here x and y. Any solution, all solutions, or a solution that meets additional properties, such as belonging to a particular interval, may be found by solving an equation, depending on the context. An optimization problem is one where the goal is to identify the solution that meets a particular criterion best. A solution is a tuple of values, one for each unknown, that satisfies all of a given set of equations or inequalities. The solution set of a given set of equations or inequalities is the set of all of its solutions. There are no values of the unknowns that satisfy all equations and inequalities simultaneously if the solution set is empty.To learn more about how to find value of x refer :

Is the given trinomial, 4x squared -20x + 25, a perfect square trinomial?
Yes, 4x² - 20x + 25 = (2x+5)² is a perfect square trinomial.
What is perfect square trinomial?
A trinomial that may be expressed as the square of a binomial is referred to as a perfect square trinomial. Remember that the square of the first term, twice the product of the first two terms, and the square of the final term are the results of squaring a binomial.
The perfect squared trinomials are always in the form:
[tex]a^2 +- 2ab + b^2 = (a+-b)^2[/tex]
The given equation can also be written as:
(2x)² - 2(2x)(5) + 5² = (2x+5)²

Define Tangent.The straight line that "just touches" the curve at a given location is referred to as the tangent line to a plane curve in geometry. It was described by Leibniz as the path connecting two points on a curve that are infinitely near together. A line that only touches a circle or an ellipse at one point is said to be tangential in geometry. If a line contacts a curve at point P, that point is referred to as the point of tangency. In other words, it is described as the line that, at that particular location, indicates the slope of a curve.
Given Data
