What is a unitary method?A unitary method is a mathematical way of obtaining the value of a single unit and then deriving any no. of given units by multiplying it with the single unit.
Given, 32 jelly beans were shared with 8 students.
The no. of jelly beans each student will get can be obtained by dividing the total no. of jelly beans divided by the total no. of students which is,
= (32/8) jellybeans each.
= 4 jelly beans each.

volcano Puu Puai in Hawaii was formed in 1959 when a massive “lava fountain” erupted. The lava shot from the ground with an initial velocity of 350 feet per second.
a. For how long was the lava in the air until it returned to the ground?
b. What was the maximum height of the lava?
c. After how many seconds did the maximum height occur?
Answers
Answer:
a)Tt = 21,41 s
b) y(max) = 1873 ft
c) t = 10,70 s
Step-by-step explanation:
We assume that this is a case of vertical shooting then:
a) Vf = V₀ - g*t
Vf = 0 -g*t = -V₀
t = V₀ /g t = 350 ft/s / 32,7 ft/s²
t = 10,70 s time for lava to reach y maximum
a) Then Tt = 2*10,7 Tt = 21,41 s
Lava was in the air for Tt = 21,41 s
b) y = y₀ + v₀*t - (1/2 )*g*t²
for y = ymax we get:
y(max) = 0 + 350*10,70 - 0,5* 32,7* ( 10,70)²
y(max) = 3745 - 1872
y(max) = 1873 ft
c) t = 10,70 s

The probability that a randomly selected reference book is hardcover is 0.4.
The two-way table depicts the distribution of books in Eliza's home by type (hardcover, paperback, biographies, fiction, and reference), as well as the number of books in each category (32 fiction books, 3 biographies, and 25 reference books).
There are a total of 25 reference books, of which 10 are hardcover.
So the probability that a randomly selected reference book is hardcover is:
10/25 = 0.4
Therefore, the probability is: 0.4.

The slope is the m in that form.
we will solve for y.
[tex]7x - 3y = 21 \\ \frac{- 7x \: \: \: \: \: \: = - 7x}{ - 3y = - 7x + 21} \\ \\ \frac{ - 3y}{ - 3} = \frac{ - 7x + 21}{ - 3} \\ y = \frac{7}{3} x - 7[/tex]

Why are whole numbers rational numbers? Use 15 as an example.
Answers
Answer:
Every whole number n can be written as a fraction of integers.
Step-by-step explanation:
Every whole number n can be written as a fraction of integers: x=x/1.
If we use 15 as an example, it would be 15 = 15/1. 15/1 is 15.
So whole numbers are rational
Whole numbers are rational numbers because all whole numbers can be expressed in the form a/b. Hence, 15 can be expressed as a rational fraction thus 15/1
When a number can be expressed in the form a/b ; such that the value of the denominator, b ≠ 0 ; then the number is said to be rational. Whole numbers are positive integer values and as such, they are not decimals. Every whole number can be expressed such that the denominator is 1 ; hence, they can be expressed in the form a/b.15 as a whole number can be rewritten as 15/1. Hence, all whole numbers are rational.

B. 5x2 - 6
C. 3x2 - 4
D. 5x2 - 4
Answers
Step-by-step explanation:
(f + g)(x) = f(x) + g(x) = (4x² + 1) + (x² - 5) = 5x² - 4. (D)
Answer:
D. 5x^2-4
Step-by-step explanation:
We are asked to find (f+g)(x), which is really just the sum of the two functions.
(f+g)(x)=f(x)+g(x)
We know the the functions are:
• f(x)= 4x^2+1
• g(x)=x^2-5
Substitute the functions in.
(f+g)(x)=(4x^2+1)+(x^2-5)
Add the functions by combining like terms. For this equation, the like terms are those with x^2 and the constants.
(f+g)(x)= (4x^2+x^2)+(1-5)
Add the terms with x^2
(f+g)(x)=(5x^2)+(1-5)
Add the constants or terms without variables.
(f+g)(x)=(5x^2)+(-4) = 5x^2-4
The sum of the functions is D. 5x^2-4

[tex]Amount = \$500[/tex] --- Maximum
Required
Determine the number of pair of jeans he can buy
To represent as an inequality, we have:

[tex]S + J \leq 500[/tex]
Substitute 2J for S
[tex]2J + J \leq 500[/tex]
[tex]3J \leq 500[/tex]
