Answer:

it says if it was the exact same size thats what i understood so it would be 605ft tall

Step-by-step explanation:

Answer:

The model is 6.05 feet tall.

Step-by-step explanation:

Now to the breakdown.

What does it mean to scale? Scaling is used for representation drawing or model is designed to tell the audience(those interested in the design) the ratio to which the design was done in respect to the actual size.

From the above definition we can scale down or scale up. To scale down is to reduce the dimensions of the actual size in our design (possibly in an effort to conserve available space). To scale up is to enlarge the dimensions of the actual size in our design (possible in an effort to show intricate and tiny parts).

Back to question, The actual size of the space needle is 605 feet to design this using the actual size will require a very large amount of resources.  So the scale model is made at a scaled down ratio of 1:100 (in a bid to manage available resources like paper size and others pertaining to the design).

1:100 means that every 1ft in the scale model represents 100ft of the actual model.

So for an Height of 605ft the scale model will have representing height of 605/100 = 6.05ft.

Answer:

12

Step-by-step explanation:

there are 60 minutes in a hour

60/20 is 3

so you muiltply 4 and 3 to get 12

Answer: 12 kilometer

Step-by-step explanation:

If he run 4 kilometer per 20 mins, it will take him one hour to run 12 kilometer.

Original

4 kilometer. X kilometer

——————- = ————————-

20 mins. 60 min

20x3 = 4x3

4x3= 12 kilometer

Answer:

A) 5 minutes

Step-by-step explanation:

What you’re looking for is where the two lines on the graph intersect, which is at 5 minutes. Therefore, they have filled the same number of barrels in 5 minutes

Answer:a I believe because it multiplies 15 by 1.5 to get 22.5

Step-by-step explanation:

Answer:

Option A

Step-by-step explanation:

Function One is represented by the graph. We can see that the slope of the First Function is positive because the formula of slope is

[tex]Slope=\frac{Change\ in\ y}{Change\ in\ x} \\\\[/tex]

And we can see that in the graph the change in y and change in x are both positive as the function is increasing because if we see the graph closely,

When x = 1 the value of y = 2 and when x = 2 the value of y = 4 and when x = 3 the value of y = 6 so the values are increasing of x and of y hence the slope is positive and the value of slope is 2.

Now the Second Function which is y = -4x here the slope is negative because the slope-intercept form of the equation is .

[tex]y=mx+b[/tex]

and the second function is

[tex]y=-4x[/tex]

if we compare both these equations we get the value of m = -4 where m is also called the slope. So the slope of the second function is negative.

So

Option B is incorrect because the slope of the first function is positive

Option C is incorrect because the slope of the second function is negative

Option D is incorrect because the slope of the first function is 2 and the slope of the second function is -4

That leaves us with Option A which is correct, where we can see that the slope of the first function is positive and the slope of the second function is negative

Answer:

A) The slope of function one is positive and the slope of function two is negative.

General Formulas and Concepts:

Algebra I

Slope-Intercept Form: y = mx + b

Step-by-step explanation:

We see that the 1st graph has a positive slope; as x increases, the y-value also increases. Therefore, the 1st graph must have a positive slope.

We are given the equation y = -4x as our second line. Using our y = mx + b form, we see that our slope m = -4. Therefore, the 2nd graph has a negative slope.

Our answer choice then would be A, as it is the only one that matches the descriptions.

Answer:

Y=1/2x-2

Step-by-step explanation:

Answer:

325 miles and 77 dollars

Step-by-step explanation:

First, create equations. Let x equal the miles driven. The first plan expression  is 38 + 0.12x and the second plan expression is 51 + 0.08x. Setting these equal and solve for x: 38 + 0.12x = 51 + 0.08x -> 0.04x = 13 -> x = 325 miles.

The cost is found by substituting it into any of the expressions: 51 + 0.08(325) = 77 or 38 + 0.12(325) = 77

Answer:

The answer is 67x - 1,526 < 2,016.

Answer:

Se below

Step-by-step explanation:

Simplifying, using formula a^2 - b^2 = (a +b)(a - b)

As  we see the resulting expression is multiple of 8
