Answer:

2. y = 25 km

Step-by-step explanation:

To find the dimensions, write a proportion. A proportion is an equation of ratios.

[tex]\frac{scale}{factor} = \frac{Actual}{Model}[/tex]

Then solve for the unknown value by cross multiplying.

2. [tex]\frac{2}{5} = \frac{10}{y}[/tex]

2y = 5*10

2y = 50

y = 25

Select the correct answer! Which point is the vertex of the graph defined by f(x) = 6|x − 2| − 5?
A. (6, 5)
B. (2, -5)
C. (0, 0)
D. (6, -2)

Answers

The Answer to your question is:

B: (2,-5)

Answer:

the vertex is (2,-5)

Step-by-step explanation:

f(x) = 6|x − 2| − 5

WE need to find out the vertex of the given absolute function

The vertex form of absolute function is

f(x) = a|x − h| +k

where (h,k) is the vertex

Now we compare the given f(x) with the vertex form

h= 2  and k = -5

so the vertex is (2,-5)

Use the provided ruler suppose you re-create the drawing so I had a scale of 1 cm to 4 cm in length and width of the new scale drawing be

Answers

Final answer:

To recreate a drawing on a new scale of 1 cm to 4 cm, simply multiply the original dimensions by the scale factor of 4.

Explanation:

If you are given a drawing and you want to recreate it on a new scale where 1 centimeter (cm) in the original equals to 4 centimeters in the new drawing, then you simply have to multiply the dimensions of the original by 4. Suppose the original drawing is 2 cm in length and 3 cm in width. Then the new length would be 2 cm * 4 = 8 cm and the new width would be 3 cm * 4 = 12 cm. Remember this is a general concept and can be applied to all dimensions of the drawing. It's a basic concept in proportion and scale factor.

Solve for x: −3|x − 3| = −6

Answers

Answer:

x = 5                         x = 1

Step-by-step explanation:

−3|x − 3| = −6

Divide each side by -3

−3/-3|x − 3| = −6/-3

|x − 3| = 2

An absolute value is equal to a positive and negative solution

x-3 =2      and      x-3 = -2

Add 3 to each side

x-3+3 = 2+3            x-3+3 = -2+3

x = 5                         x = 1

there are four students in each small reading group there are 24 students in all.
how many reading groups are there​

Answers

Answer:

6

Step-by-step explanation:

24 / 4 = 6

Final answer:

The number of reading groups can be determined by dividing the total number of students, which is 24, by the number of students in each group, which is 4. The calculation is 24 ÷ 4, resulting in 6 reading groups.

Explanation:

To find the number of reading groups, we can use a simple division operation because we are dividing a larger group of items (students) into smaller equal-sized groups. In this case, we have 24 students and want to find out how many groups of 4 students we can create from that total.

Here's the step-by-step explanation:

Identify the total number of students, which is 24.

Identify the number of students in each reading group, which is 4.

Divide the total number of students by the number of students in each group: 24 ÷ 4 = 6.

Therefore, there are 6 reading groups.

what is the height and length of a rectangular box with a volume of 6x^2-600 with a width of 6

Answers

Answer:

(x+10) and (x-10)

Step-by-step explanation:

The volume of a rectangular box is defined as

Volume = width*height*length

In this case

Volume  = 6x^2-600  =  6*(x^2 - 100)

And we also know,

Volume  =  (6)*height*length

So,

6*(x^2 - 100) = (6)*height*length

This means that

height*length = (x^2 - 100)

height*length = (x+10)*(x-10)
