Five boys each have 8 marbles. If all
their marbles are collected and placed
into
8heaps, how many marbles will there be in each jeap ?
5 marbles.
We first need to find how many marbles we have in total.
8 marbles * 5 boys = 40 marbles.
These 40 marbles will now be divided by 8, since we are taking the total amount of marbles we have and separating them into 8 different piles.
40/8 = 5
There will be 5 marbles in each heap.
Mrs. Turner planted seeds for a science fair project.

in the height of the plants in cm/day?
(fill out the chart)
PLEASE HELP IM FAILING
The rate of change (slope) in the height of the plants in cm/day is 0.3 cm/day.
We are given that Mrs. Turner planted seeds for a science fair project. After 2 days, the plants were 2 cm tall. After 10 days, the plants were 5 cm tall. We need to find the rate of change (slope) in the height of the plants in cm/day.
Let us first find the change in the height of the plants:
Change in height = Final height - Initial height
= 5 cm - 2 cm
= 3 cm
The change in height in 10 days is 3 cm. To find the rate of change (slope) in the height of the plants in cm/day, we divide the change in height by the time taken:
Rate of change (slope) in the height of the plants in cm/day = Change in height / Time taken
= 3 cm / 10 days
= 0.3 cm/day
Therefore, the rate of change (slope) in the height of the plants in cm/day is 0.3 cm/day.

Denise is designing the seating arrangement for a concert at an outdoor theater. to give everyone a good view, each row must have 6 more seats than the row before it, and the 1st row can only have 11 seats. explain to denise how to create an equation to predict the number of seats in any row. then, using your equation, show your work to determine the number of seats in row 18
An equation is formed of two equal expressions. The number of seats in row 18 will be 119.
What is an equation?An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
A.) Given the number of seats that the first row can have is 11, while the number of seats that the next row should have is six more than the previous one. Therefore, the number of seats will increase linearly.
Thus, the equation for the number of seats in any row can be given as y=11+6x, where y is the number of seats and x is the number of row.
B.) The number of seats in row 18 will be equal to,
y = 11 + 6x
y = 11 + 6(18)
y = 11 + 108
y = 119
Hence, the number of seats in row 18 will be 119.

(b) The variable brthord is birth order (one for the first-born child, two for a second-born child and so on). Explain why brthord could be used as an instrument for educ in equation (1). That is, does this variable satisfy the relevance and exogeneity conditions for it to be an appropriate instrument?
(a) The variable educ might be endogenous
(b) The variable brthord is birth order (one for the first-born child, two for a second-born child and so on) could be used as an instrument for educ in equation
a) The variable instruction might be endogenous because as compensation increases the income expansions which additionally make able to an individual more educating himself. So there is an opportunity for the instruction might be an endogenous variable.
The indigeneity may involve the 32 the coefficient of knowledge as well different variables like married, black, south, urban, etc.
b) There is a substantial high relationship exists between birth order and the status of teaching. it is more possible to have higher schooling with less the order of child-born and the birth order is autonomous of the error term as well with wage. So the variable "birth order" is a good variable to use as an agency for the endogenous variable instruction.

(8 points) Write the following numbers in the form a + bi (recall that powers and log's are not uniquely defined) with a, b E R. log(1) • log(-1) log(i) ii
The given expressions can be written in the complex form a + bi as follows,
1. log(1) = 0 + 0i
2. log(-1) = 0 + πi
3. log(i) = 0 + (1/2)πi
4. ii = e^(-π/2) + 0i
The given expressions can be written in the form a + bi, where a and b are real numbers, and i is the imaginary unit.
1. log(1)
Since log(1) = 0, we can write it as 0 + 0i.
2. log(-1)
Using the complex logarithm, log(-1) can be expressed as πi, so it is 0 + πi.
3. log(i)
The complex logarithm of i is (1/2)πi, so we can write it as 0 + (1/2)πi.
4. ii
To find ii, we first need to express i in exponential form. i = \(e^{\frac{i\pi }{2} }\), so:
ii = \((e^{\frac{i\pi }{2} })^{i}\)
Using the power rule for exponentials (a^(mn) = (a^m)^n):
ii = \(e^{\frac{-\pi }{2} }\)
This can be written as \(e^{\frac{-\pi }{2} }\) + 0i.
So, the given expressions can be written in the form a + bi as follows:
1. log(1) = 0 + 0i
2. log(-1) = 0 + πi
3. log(i) = 0 + (1/2)πi
4. ii = \(e^{\frac{-\pi }{2} }\) + 0i

Find the least common denominator for these two rational expressions -8/y^2 , 3/6y
Both rational expressions' least common denominator is 6\(y^{3}\)
LCD, what is it?The denominator of a group of fractions with the lowest common multiple is known as the lowest common denominator (Lowest Common Multiple, or LCD for short). For many denominators in the collection, LCD is the smallest positive integer. In writing fractions, as 3/4, a fraction bar is used.
According to the given information:The mathematical expressions are -8/y^2 and 3/6^y.
Let's factorize the denominators right now.
\(y^{2}\) = y,y
6y = 6,y
To locate the common component among the terms, we must now group them.
y,y and 6,y
We now need to determine which fraction has the lowest common denominator.
We must first take the common and missing components, then combine them to obtain the least common factor in order to discover the least common denominator.
The common factor in both denominators is equal to y.
The first rational expression's missing element is equal to 6.
The second rational expression's second missing element is y.
Thus, the rational expression's least common denominator is equal to 6\(y^{3}\).

a cylindrical glass is half full of lemonade. the ratio of lemon juice to water in the lemonade is $1:11$. if the glass is $6$ inches tall and has a diameter of $2$ inches, what is the volume of lemon juice in the glass? express your answer as a decimal to the nearest hundredth.
The volume of lemon juice in the glass is 0.38 cubic inches.
Explanation:
Given,
Let the volume of the lemonade in the glass be V cubic inches
Therefore, the volume of lemon juice in the lemonade is \($\frac{1}{12}$\) V cubic inches
Volume of water in the lemonade is \($\frac{11}{12}$\) V cubic inches
The volume of the cylindrical glass is given by:
\($V_{\text{cylindrical glass}} = \pi r^2h$\)
Here,
Radius r = 1 inch
Height h = 6 inches
\($V_{\text{cylindrical glass}} = \pi r^2h = \pi (1)^2(6) = 6 \pi$\)
Since the glass is half full of lemonade, the volume of lemonade in the glass is:
\($V_{\text{lemonade}} = \frac{1}{2}V_{\text{cylindrical glass}} = \frac{1}{2} 6 \pi = 3\pi$\)
The volume of lemon juice in the lemonade is given by:
\($V_{\text{lemon juice}} = \frac{1}{12}V$\)
Therefore
\($V_{\text{lemon juice}} = \frac{1}{12}3\pi = \frac{1}{4}\pi = 0.7854$\) cubic inches
Hence, the volume of lemon juice in the glass is 0.38 cubic inches (rounded to the nearest hundredth).

we know that when x= 2 y = 15
So we can write
15=a(2+1)²-3

2. hypotenuse is 7.8
3. hypotenuse is 9.8
4. hypotenuse is 3.6
Step-by-step explanation:
To find the hypotenuse, just use the formula a^2 + b^2 = c^2
a and b are the sides with short lengths, while c is the one with the greatest line.
Let's try #1, and then you can do the rest by yourself, as it is very easy.
1) sides a and b are given, a = 7 and b = 24
hypotenuse = a^2 + b^2 = c^2
--> 7a^2 + 24b^2 = c^2
--> 49 + 576 = c^2
--> 625 = c^2
--> take the square root of 625
--> 25 = c

Probability:
Possibility is referred to as probability. This branch of mathematics deals with the occurrence of a random event. The value's range is 0 to 1. Probability has been applied into mathematics to predict the likelihood of different events. Probability generally refers to the degree to which something is likely to occur. This fundamental theory of probability, which also applies to the probability distribution, can help you comprehend the possible outcomes for a random experiment. Gonna determine how likely something is to occur, use probability. Many things are hard to predict with 100% certainty. We can only anticipate the possibility of an event occurring using it, or how likely it is.
