All tests for the first six chapters of a textbook had 20–30 questions. The chapter 7 test will be given tomorrow. What reasonable conclusion can you make?
The chapter 7 test will have 20-30 questions on it. Novanet!
Answer:
We can conclude that the chapter 7 test will also have 20-30 questions on it.
Step-by-step explanation:
All tests for the first six chapters of a textbook had 20–30 questions.
The chapter 7 test will be given tomorrow.
Hence, based on reasoning, we can say that the chapter 7 test can also have 20-30 questions in it.
The probability is also high as all the 6 previous tests had 20 to 30 questions. Hence, it is very likely that the 7th test will also have same number of questions.
Harry pays $3.50 sales tax on a $70 item. What is the sales tax rate?
The answer is 5% tax rate for the item. Work shown below.
Harry pays 5% of the cost as sales tax.
What is Equation Modelling?
Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.
We have Harry who pays $3.50 sales tax on a $70 item.
Assume that the sales tax rate is x%. Then -
x = (3.5/70) x 100
x = 5%
Therefore, Harry pays 5% of the cost as sales tax.

Tickets to a concert cost $2 for children, $3 for teenagers and $5 for adults. When 570 people attended the concert, the total ticket receipts were $1950. Three-fourths as many teenagers as children attended. How many adults attended?
Answer: 220
Step-by-step explanation:
Children (x): $2
Teens (y): $3, [tex]\frac{3}{4}x[/tex]
Adults: (z): $5
Quantity: x + y + z = 570 ⇒ x + [tex]\frac{3}{4}x[/tex] + z = 570 ⇒ 1.75x + z = 570
Cost: 2x + 3y + 5z = 1950 ⇒ 2x + 3[tex](\frac{3}{4}x)[/tex] + 5z = 1950 ⇒ 2x + 2.25x + 5z = 1950 ⇒ 4.25x + 5z = 1950
Qty: 1.75x + z = 570 → 5(1.75x + z = 570) → 8.75x + 5z = 2850
Cost: 4.25x + 5z = 1950 → -1(4.25x + 5z = 1950 → -4.25x - 5z = -1950
4.50x = 900
x = 200
Teens (y): [tex]\frac{3}{4}x[/tex]
y = [tex]\frac{3}{4}(200)[/tex]
= [tex]\frac{600}{4}[/tex]
= 150
Quantity: x + y + z = 570
200 + 150 + z = 570
350 + z = 570
z = 220
the volume of a rectanglar box is 15,552 cubic inches. What is the volume of the box in cubic feet?
One (1) foot is equal to twelve (12) inches.
12 inches cubed is 1728.
Divide 15,552 by 1728
The answer is 9 cubic feet.
If you have any further questions feel free to ask.
Hope this helps.
The volume of the box is 9 cubic feet.
What is the volume of the cube?The volume of a cube is equal to the product of the length, width, and height of a cube.
The volume of a cube is length × breadth× height
What are Arithmetic operations?Arithmetic operations can also be specified by the subtract, divide, and multiply built-in functions. Operators which let do a basic mathematical calculation
/ Division operation: Divides left-hand operand by right-hand operand
For example 4/2 = 2
Given that,
Volume of a box = 15,552 cubic feet
Since one foot is equal to twelve inches.
We are to convert the dimension to cubic feet.
Using the conversion factor
∵ 1 feet = 12 inches
∴ 1 cubic foot = 1728 cubic inches
Divide 15,552 by 1728
⇒ 15,552/1728
⇒ 9
Hence, the volume of the box is 9 cubic feet.

The number of yellow fish at the aquarium is 5 fewer than 3 times the number of blue fish. The table shows how the number of yellow fish, y, depends on the number of blue fish, b. Choose the equation which represents the rule.
Answer:
If you are on USATestPrep (which you most likely are) the correct answer is C.
Step-by-step explanation:
C) y = 3b − 5
It is “5 fewer than 3 times”
Answer:
y = 3b-5
Step-by-step explanation:
The number of yellow fish is 5 fewer than 3 times the number of blue fish. Using b to represent the number of blue fish, 3 times this is 3b; 5 fewer than this is 3b-5. This gives us the equation
y = 3b-5

The statement that correctly describes the pattern 20, 25, 30, 35, ... is that it contains only factors of 5.
The given sequence of numbers is 20, 25, 30, 35,... and the correct statement describing this pattern is that it contains only factors of 5. This is because each number in the sequence is a multiple of 5 and can be divided by 5 without leaving a remainder. The sequence is not exclusively even or odd numbers, as it contains both (20 and 30 are even, while 25 and 35 are odd). Also, the pattern is not decreasing; it is instead increasing by increments of 5.

Find two numbers if their ratio is 9:11 and their difference is 6.
Answer: The required numbers are 27 and 33.
Step-by-step explanation: We are given to find two numbers if their ratio is 9:11 and their difference is 6.
Let the two numbers be 9x and 11x.
Then, according to the given information, we have
[tex]11x-9x=6\\\\\Rightarrow 2x=6\\\\\Rightarrow x=\dfrac{6}{2}\\\\\Rightarrow x=3.[/tex]
Therefore, the numbers are
[tex]9x=9\times3=27,\\\\11x=11\times3=33.[/tex]
Thus, the required numbers are 27 and 33.
To find the two numbers, we set up an equation based on the given conditions and solve for x. The two numbers are found by multiplying x by the ratio values.
Explanation:To find two numbers with a ratio of 9:11 and a difference of 6, we can set up the following equations:
Let the numbers be 9x and 11x.
According to the given conditions:
11x - 9x = 6
Simplifying the equation, we get:
2x = 6
Dividing both sides of the equation by 2, we find:
x = 3
Therefore, the two numbers are 9(3) = 27 and 11(3) = 33.
So, the two numbers are 27 and 33.

what is 6 7/8 + 7 5/12
[tex]6 \: \frac{7}{8} \: + 7 \frac{5}{12} [/tex]
Here is your equation:
[tex]6 \frac{7}{8} + 7 \frac{5}{12}[/tex]
As you can see, the denominators, which is the bottom number in the fraction, are different. You need to have the same denominator, so that you can add it. To change the denominators, you need to find the LCM of both denominators, which is 8 and 12. To find the LCM, first list the multiples of both numbers and see what is common.
[tex]8 - 8, 16, 24, 32, 40, 48, 56 \\12-12, 24, 36, 48[/tex]
The only common number is 48. That means you need to change both fractions so that they have a denominator of 48.
[tex]6 \frac{7 \times 6}{8 \times 6} \rightarrow 6 \frac{49}{48}[/tex]
[tex]7 \frac{5 \times 4}{12 \times 4} \rightarrow 7 \frac{20}{48}[/tex]
Here is your new equation:
[tex]6 \frac{49}{56} + 7 \frac{20}{48}[/tex]
Add:
[tex]6 \frac{49}{48} + 7 \frac{20}{48} = 13 \frac{69}{48}[/tex]
Simplify:
[tex]13 \frac{69}{48} \rightarrow 14 \frac{21}{48} \rightarrow 14 \frac{7}{16}[/tex]
Your answer is 14 [tex]\frac{7}{16}[/tex]

Answer: The correct option is 4th, i.e., [tex]\frac{7}{11}= \frac{10}{AC}[/tex].
Explanation:
It is given that ABC is similar to XYC. If BY = 4, YC = 7, XC = 10.
Draw a diagram by using the given information.
From the figure,
[tex]BC=BY+YC[/tex]
[tex]BC=4+7[/tex]
[tex]BC=11[/tex]
If the two triangles are similar then their corresponding sides are is in proportion and the corresponding angle are same.
[tex]\frac{YC}{BC}=\frac{XC}{AC}[/tex]
[tex]\frac{7}{11}=\frac{10}{AC}[/tex]
Therefore, the correct option is 4th.

35 rounded to the nearest hundred
Answer and Explanation: 35 rounded to the nearest 100 is 0. To round to the nearest hundred, you need to first identify the hundreds that are closest to the number you are rounding. For 35, the closest hundred that is lower than 35 is 0, and the closest 100 that is higher than 35 is 100.
The rounding of 35 to the nearest hundred gives us 0.
To round 35 to the nearest hundred, we need to determine which hundred it's closest to. In this case, we can see that 35 is near to 0 than to 100.
When rounding to the nearest hundred, we look at the number in the knock outs place.
However, we round up, and if it's lower than 5, If it's 5 or lesser.
In the number 35, the knockouts number is 3.
Since 3 is lower than 5, we round down.
When we round down, we keep the hundreds number as is and replace all the integers to the right with bottoms.
Thus, rounding 35 to the nearest hundred gives us 0.
