The school gym can hold no more than 650 people. The bleachers will seat 176 people. The PTA is setting up 25 rows of chairs for their meeting. At most, how many chairs can be in each row?
A) 18
B) 19
C) 26
D) 27
Answers
650 - 176 = 474
474 / 25 = 18.96
You cannot round in the situation because you can't have 18.96 of a chair. It's either whole or it's not going to be built.
Answer:
A)18
Step-by-step explanation:
The number of chairs in the school gym can be represented by inequality 176 + 25c ≤ 650, where c represents the number of chairs in each row. When you solved for c, we find that c = 18.96. Since you cannot have a fraction of a chair, we know that the maximum number of chairs in each row must be 18.
Hope this helps!!!!!!!!!!!!!!!!!!!!!!!!

If y=-7 when x=-21, what is the value of x when y=9
Answers
So then when y=9, 9=x-21.
Solve for x.
x=9+21
x=30
If y = -7 when x = -21, then y = (1/3)x, and (1/3) is the constant of proportion.
A similar truth is that x = 3(y), as -21 = 3(-7)
So, if y=9, x = 3(9) = 27

After m months, the height of a plant is 10+3m millimeters. How tall is the plant after 8 months? 3 years?
Answers
After 8 months, the plant is 34 millimeters tall, and after 3 years (36 months), it's 118 millimeters tall.
To find the height of the plant after 8 months and 3 years, let's first understand the pattern. The height is given by the equation ( 10 + 3m ), where ( m ) represents the number of months.
Height after 8 months:
Substituting ( m = 8 ) into the equation:
[tex]\( \text{Height} = 10 + 3(8) \)[/tex]
[tex]\( \text{Height} = 10 + 24 \)[/tex]
[tex]\( \text{Height} = 34 \)[/tex] millimeters.
Height after 3 years (36 months):
Substituting ( m = 36 ) into the equation:
[tex]\( \text{Height} = 10 + 3(36) \)[/tex]
[tex]\( \text{Height} = 10 + 108 \)[/tex]
[tex]\( \text{Height} = 118 \)[/tex] millimeters.
So, after 8 months, the plant is 34 millimeters tall, and after 3 years (36 months), it's 118 millimeters tall.

Question 2: The answer is: " -12.8 ".

Question 3: The answer is: " 12.3 " .

Explanation:

Question 1:
_______________________________________________________
(-4/3) − (-3/2) = [tex] \frac{-4}{ 3} [/tex] + [tex] \frac{3}{2}[/tex] ;
→ The least common multiple (LCM) of the numbers "2" and "3" (which are the numbers in the denominators) is: "6" ; so we can convert each fraction value to the equivalent fraction with a denominator of "6" ;
→ [tex] \frac{-4}{3} [/tex] = [tex] \frac{?}{6} [/tex] ;
→ What value is the "?" ? ; → Look at the denominators.
→ (3 * ? = 6); → (6÷3 = 2).
→So; [tex] \frac{-4}{3} [/tex] = [tex] \frac{-4*2}{3*2} [/tex] ;
= [tex] \frac{-8}{ 6} [/tex] ;
_______________________________________________________
→ Now; → [tex] \frac{3}{2} [/tex] = [tex] \frac{?}{6} [/tex] ;
→ What value is the "?" ? ; → Look at the denominators.
→ (2 * ? = 6); → (6÷2 = 3).
→So; [tex] \frac{3}{2} [/tex] = [tex] \frac{3*3}{ 2*3} [/tex] ;
= [tex] \frac{9}{6} [/tex] ;
_______________________________________________________
Now, we can rewrite the problem:
________________________________
→ [tex] \frac{-8}{ 6} [/tex] + [tex] \frac{9}{ 6} [/tex] ;
= [tex] \frac{-8+9}{6}[/tex] ;
= [tex]\frac{1}{6} [/tex] .

Mr. Venn knows that 60% of his students will score no more than 5 points above or below the class average,75% on the test.
Write an inequality that represents the test scores of 60% of his students?
Answers
Answer:
[tex]70\leq x\leq 80[/tex]
Step-by-step explanation:
Let x represent the test scores of 60% of his students.
We have been given that Mr. Venn knows that 60% of his students will score no more than 5 points above or below the class average,75% on the test.
We will use tolerance formula to solve our given problem.
[tex]|\text{Actual}-\text{Ideal}|\leq\text{Tolerance}[/tex]
[tex]|x-75|\leq5[/tex]
Using rule [tex]|u|\leq a[/tex], then [tex]-a\leq u\leq a[/tex], we will get:
[tex]-5\leq x-75\leq5[/tex]
[tex]-5+75\leq x-75+75\leq5+75[/tex]
[tex]70\leq x\leq 80[/tex]
Therefore, the inequality [tex]70\leq x\leq 80[/tex] represents the test scores of 60% of Mr. Venn's students.

And never forget to label your units!
The perimeter of the rectangle is 138 inches.
To get the area, multiply the sides by each other.
30 x 39 = 1170
The area of the rectangle is 1170 inches^2, or 1170 inches squared.
Area is 1170 (30*39)

Step-by-step explanation:
We are given the following information in the question:
Percentage of students at Rockwood Junior High School who speak Spanish = 12%
Number of students at Rockwood Junior High School who speak Spanish = 36
We have to find the total number of students who surveyed:
Formula:
Let x be the total number of students who were surveyed.
[tex]12\% \text{ of }x = 36\\\\\displaystyle\frac{12}{100}\times x = 36\\\\x = \frac{36\times 100}{12}\\\\x = 300[/tex]
