A school requires that 1 adult accompany every 8 students on a field trip. How many adults are needed to accompany 32 students?
Answer: 4 adults are needed to accompany 32 students.
Step-by-step explanation:
Given: School requires 1 adult to accompany every 8 students on a field trip.
The number of adults are needed to accompany 32 students = [tex]\dfrac{32}{\text{Number of students accompanied by an adult}}[/tex]
[tex]=\dfrac{32}{8}\\\\=4[/tex]
Hence, 4 adults are needed to accompany 32 students.

Find the slope of each linear graph to solve the riddle.
( i just need help with V)
Answer:
slope=15÷10=1.5 or 3/2
Step-by-step explanation:
slope=rise÷run
10 right 15 up
slope=15÷10=1.5 or 3/2
The slope is calculated as the ratio of the rise and run. The slope of the given line will be [tex]\dfrac{3}{2}[/tex].
In mathematics, slope refers to the measure of the steepness or inclination of a line. It describes how much a line slants or rises/falls as it moves horizontally.
A positive slope means the line is upward-sloping, rising from left to right, while a negative slope indicates a downward-sloping line.
The slope can be calculated by the ratio of the rise and the run. The points on the given graph are A(10,30) and B(20,45). The slope is calculated by the formula written below,
[tex]m = \dfrac{y_2-y_1}{x_2-x_1}[/tex]
The slope of the line is calculated below
[tex]m = \dfrac{y_2-y_1}{x_2-x_1}\\m = \dfrac{45-30}{20-10}\\m = \dfrac{3}{2}[/tex]
The slope of the line will be [tex]\dfrac{3}{2}[/tex].

For questions 1-4, find the distance between points A and B. Round your solutions to the nearest tenth when necessary.
Answer:
1. AB= 8.94,
2. AB= 7.28
3. AB= 16.4
4. AB= 19.21
Step-by-step explanation:
This is fun! Well you have to find the (1,4) (or point e) point and count the distance to the other points point a and point b.
4 units from a to e and 8 b to e
a² + b² = c²
8² + 4² = c²
64 +16 = c
√80 = √c²
8.94 = c
It dose not matter which units you plug in for a and b but c has to be the long side of the triangle/ hypotonuse.

What is the volume of a cylinder, in cubic centimeters, with a height of 2 centimeters
and a base diameter of 20 centimeters? Round to the nearest tenths place
Answer:
V ≈ 628.3 cm³Step-by-step explanation:
Volume of cylinder: V = π×r² × h
diameter = 20 cm ⇒ r = 10 cm
h = 2 cm
Volume:
V = π×(10)²×2 = 200π cm³ = 628.318.... cm³ ≈ 628.3 cm³

PLZ ANSWER ASAP! LOGS
Answer:
[tex]\displaystyle \log_7\frac{1}{81}\approx -2.2[/tex]
Step-by-step explanation:
We want to find:
[tex]\displaystyle \log_7{\frac{1}{81}}[/tex]
First, using the quotient rule:
[tex]\displaystyle \log_b\frac{a}{c}=\log_b a-\log_b{c}[/tex]
We can rewrite our expression as:
[tex]=\log_7 1-\log_7 81[/tex]
The logarithm of 1 is always 0. Therefore:
[tex]=-\log_781[/tex]
We can rewrite this as:
[tex]=-\log_7 9\cdot 9[/tex]
Using the product rule:
[tex]\log_b ac=\log_ba+\log_bc[/tex]
This is equivalent to:
[tex]=-(\log_79+\log_79)[/tex]
Substitute:
[tex]=-(1.1+1.1)=-2.2[/tex]

i think thats the answer :3
Step-by-step explanation:
Solve the inequality. 5(x + 1) – 10 ≥ 2x + 3(x + 2)
The solution of the inequality 5(x + 1) - 10 ≥ 2x + 3(2x + 2) is x ≤ - 16/3.
What are inequalities and their types?Inequality is a relation that compares two numbers or other mathematical expressions in an unequal way.
The symbol a < b indicates that a is smaller than b.
When a > b is used, it indicates that a is bigger than b.
a is less than or equal to b when a notation like a ≤ b.
a is bigger or equal value of an is indicated by the notation a ≥ b.
Given, Inequality is 5(x + 1) - 10 ≥ 2x + 3(2x + 2).
5x + 5 - 10 ≥ 2x + 6x + 6.
5x + 5 - 10 ≥ 8x + 6.
5x - 8x ≥ 10 + 6.
- 3x ≥ 16.
3x ≤ - 16.
x ≤ - 16/3.
