Answer:
[tex]27[/tex]
Step-by-step explanation:
We start by setting an equation. We have [tex]2x+x+9=90[/tex] which simplifies to [tex]3x+9=90[/tex]. Subtract [tex]9[/tex] from both sides leaves us to solve for x when [tex]3x=81[/tex] divide by [tex]3[/tex] on both sides, we get [tex]x=27[/tex].

1. At the book sale, all books cost less than $5.
A. What is the most expensive a book could be? $[4.99]
B. Write an inequality to represent costs of books at the sale. [ ]
C. Describe the number line that represents this inequality. The circle has an (open/closed)
{ } dot on the 5, and the arrow is pointing to the (left/right)
{ } of the 5.
Answers
B. Books (B) < $5 OR Books (B) ≤ $4.99
C. The number line would begin at 5 on the number line with an open circle. The arrow and line point to the left.
Reasoning for each answer:
A. The cost of the books all cost LESS than $5. This means no book can be $5 or greater. With this in mind, $4.99 is the largest possible value of a book.
B. < means less than, and ≤ means less than or equal to. For this reason you could either write B < $5 (meaning that a book can cost LESS than $5) OR you could write B ≤ $4.99 (meaning that a book can cost LESS than or EQUAL to $4.99)
C. An open circle means that the number is not included we are trying to show that the value of the books are LESS than $5. Meaning, an open dot above 5 pointing to the left shows that a book can’t cost $5, but CAN cost anything LESS than $5.

The formula for circumfrence is C=pi x 2r or C= pi x r
In this case its C= 3.14 x 9 which is 28.26 rounded to 28.3
Answer:
Answer A is correct.
Step-by-step explanation:
Formula to find the circumference of a circle is :
C = π × d
Here,
d ⇒ diameter ⇒ 9m
First, let us find the circumference in terms of π.
C = π × d
= π × 9
= (9π)m
And now let us find the circumference to the nearest 10th.
Given that,
π = 3.14
Let us find now.
C = 9π m
= 9 × 3.14 m
= 28.26 m
≈ 28.3m
The area of a circle is approximately 28.27 square feet. What is the length of the diameter?
Answers
Answer:
d = 6 ft.
Step-by-step explanation:
[tex]A=\pi r^{2}[/tex]
[tex]28.27=\pi r^{2}[/tex]
[tex]r=\sqrt{\frac{28.27}{\pi } } =3[/tex]
diameter = 2 r = 2(3) = 6 feet

Good Afternoon. can someone answer this for me? IF YOU DONT HAVE AN ANSWER SIMPLY COMMENT DONT ANSWER BUT NOT ANSWER FOR THE POINTS PLEASE
Answers
Let’s start with the first one: The angles are 29 and 105. So if the triangle equal to 180 degrees we have to add 29 and 105 and subtract from 108. 29 +105=134, 180-134=46.
Question 1= 46 degrees
So if you follow the same method for all the triangles you will get your answers.
I will show you how to do the second one: A straight line is also equal to 180 degrees so angle 1+2=180 degrees. To find the area of the triangle you will do 55+78 which equals 133. So to find angle 2 you do 180-133=47 but the question asks for angle 1. Si nce a straight line is 180 degrees you do 180-47=133
Question 2=133 degrees
For question 3 you would follow the same way as question 2.

Each question is a division, and they want to know which mixed number is equivalent. I can help.
Answer:
28 ÷ 20 = 1.4 [tex]1\frac{2}{5} = \frac{7}{5} = 1.4[/tex]
18 ÷ 4 = 4.5 [tex]4\frac{1}{2}[/tex] [tex]= \frac{9}{2}[/tex] [tex]= 4.5[/tex]
9 ÷ 8 = 1.125 [tex]1\frac{1}{8}[/tex] [tex]= \frac{9}{8}[/tex] [tex]= 1.125[/tex]
11 ÷ 6 = 1.8333... [tex]1\frac{5}{6}[/tex] [tex]= \frac{11}{6} = 1.8333...[/tex]
12 ÷ 17 = 0.70588235 [tex]\frac{12}{17} = 0.70588235[/tex]
Steps:
1. In order to find your equivalent fraction you need to divide your equations. The dividing goes for the fractions too.
2. If you don't know how to divide mixed numbers I can show you one of the fractions.
Example:
4[tex]\frac{1}{2}[/tex]
multiply 4 x 2 4 x 2 = 8 add 8 + 1 8 + 1 = 9 convert into improper fraction [tex]\frac{9}{2}[/tex] denominator always stays the same. divide [tex]\frac{9}{2}[/tex] [tex]\frac{9}{2} = 4.5[/tex]3. now after dividing your fraction and equation it should turn out as a decimal.
4. check if the equation has the same decimal if they do they're equivalent.

easy question: A train travels 30 miles in 1/3 of an hour. Whats is the trains average speed
Answers
Answer:
90 MPH
30 / (1/3) = 90
Answer:
90mph
Step-by-step explanation;
if an object travels 30 miles in the first part of an hour, and the speed is constant, then we can assume 30*3=90
in the first third, it went 30 mi, in the second it went 30mi, and in the last part it went 30 mi
30+30+30=90
or you could do 30* the denominator (in this case its 3), so 30*3=90

The volume of this right prism is 240.5 ft³.
What is the height, x, of the prism?
Enter your answer as a decimal in the box.
x = (Answer) ft
Answers
Answer:
x = 7.4 ft.
Step-by-step explanation:
Find the area of the base (32.5ft^2) and divide the area by that to find the height (240.5/32.5= 7.4ft)
The height of the prism is 7.4 feet.
What is Volume?Volume of a three dimensional shape is the space occupied by the shape.
Given is a right trapezoidal prism.
Area of the prism = Base area × Height of the prism
Base is trapezoid.
Base area = [tex]\frac{1}{2}[/tex] (8 + 5) 5
= 32.5 feet²
Height of the prism = Length between the bases = x feet
So we have,
32.5 x = 240.5
x = 240.5 / 32.5
x = 7.4 feet
Hence the height of the prism is 7.4 feet.

Q6: What is the measure of 2 if 1 is (2x - 3) and 2 is (8x)?
Answers
Answer:
168 degrees
Step-by-step explanation: first you would do (2x-3)+8x so you would have 10x-3 and that equals 180 degrees since its a straight angle. so you would do 10x-3=180 divide by 10, x-3=18 and add 3 so x=21 then since 2 is 8x you would multiply 8 by 21 which is 168.
