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.

The solution of the inequality  5(x + 1) - 10 ≥ 2x + 3(2x + 2) is x ≤ - 16/3.

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.

step 2. a12 = -60 + 32

step 3. a12 = -28.

Answer:

Step-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

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].

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]
