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.

The total distance around the garden is 96 feet.

Step-by-step explanation:

We are given a rectangular garden which is 30 feet by 6 yards.

In order to solve this problem, first we have get our units right. We decide to work with feet.

1 yard = 3 feet.

Therefore,

6 yard = 18 feet.

Thus, in feet we have a rectangular garden which is 30 feet by 18 feet.

Therefore the total distance around the garden—i.e its perimeter—is:

Answer: f(-3) = 26

The number of students in Mr. Boggs’s homeroom

is equal to b. Add the total number of students in

each class and set it equal to 90.

90 = b + 1.5(b + 2) + 15 + (2b – 9)

Use the Distributive Property, and collect like terms.

90 = b + 1.5b + 3 + 15 + 2b – 9

90 = 4.5b + 9

The equation to find out the number of students in Mr. Bogg's homeroom when the total number of students is 90, is 'x = 90', where x represents the number of students in Mr. Bogg's homeroom.

To write an equation to solve this problem, we'll define a variable, let's say x, to represent the number of students in Mr. Bogg's homeroom. If we know that the total number of students is 90, then the equation becomes simple: x equals 90. Thus, the complete equation would be: x = 90.

This equation states that the number of students in Mr. Bogg's homeroom (x) is equal to 90. To solve it, you just need to look at the number on the other side of the equals sign, which in this case is 90. Therefore, according to this equation, Mr. Bogg's homeroom has 90 students.

-9/10 - 2/5 is -13/10... or -1 3/10

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.

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.

A rectagle has 4 sides. There are 2 lengths and 2 widths.

The would be written like this to start with

P = 2L + 2W             Using the distributive property 2 can be taken outside the brackets

P = (2L + 2W)

P = 2(L + W)              You have shown how the 4 sides can be written more efficiently.

Harry pays 5% of the cost as sales tax.

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.

f(3) = 1

substitute x = 3 into f(x)

f(3) = (2 × 3) - 5 = 6 - 5 = 1

To find the value of f(3) for the function f(x) = 2x - 5, substitute x = 3 into the function. The value of f(3) is 1.

To find the value of f(3) for the function f(x) = 2x - 5, we substitute x = 3 into the function.

So, f(3) = 2(3) - 5.

Simplifying further, we get f(3) = 6 - 5 = 1.

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.

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.
