A building blueprint has a scale of 2 inches equal to 25 feet. on the blueprint, the 10 story building has a height of 12 inches what is the actual height of 1 story

Answers

Answer 1

Answer:

Answer:

The actual height of 1 story is 15 feet.

Step-by-step explanation:

The given scale is

$2 \ inches = 25 \ feet$

We know the 10 story building has a height of 12 inches, but we need the actual height of 1, that is, the height of 1 story in feet.

Let's divide to find the number of inches per story

$(12)/(10)=1.2$

There are 1.2 inches per story.

Now, we know $2 \ inches = 25 \ feet$ , let's use the rule of three

$x=1.2in(25ft)/(2in)= 15ft$

Therefore, the actual height of 1 story is 15 feet.

Answer 2

Answer: 2 inches: 25 feet.

1 inch: 25/2 feet

1 inch = 12.5 feet.

12 inches = 12.5 * 12 feet

= 150 feet.

The 12 inches height has an actual height of 150 feet.

The image shows a geometric representation of the function f(x) = x2 – 2x – 6 written in standard form.What is this function written in vertex form?

f(x) = (x –1)2 – 7

f(x) = (x +1)2 – 7

f(x) = (x –1)2 – 5

f(x) = (x +1)2 – 5

Answers

we know that

To find the equation in vertex form, we need to factor the function

$f(x) = x^(2) - 2x - 6$

Complete the square. Remember to balance the equation

$f(x) = x^(2) - 2x +1-1- 6$

$f(x) = x^(2) - 2x +1-7$

Rewrite as perfect squares

$f(x) = (x-1)^(2) -7$

in this problem

the vertex is the point $(1,-7)$

therefore

the answer is

The function written in vertex form is equal to $f(x) = (x-1)^(2) -7$

The cost of a jacket increased from $75.00 to $87.75. What is the percentage increase of the cost of the jacket?

Answers

1) we have to calculate the increase of the cost of the jacket.
Increase of the cost of the jacket=new price - previous price
increase of the cost of the jacket=$87.75 - $75.00=$12.75

2)Now, we calculate the percentaje incresae of the costo of the jacket by the rule of three.
$75=100%

$75------------------100%
$12.75------------- x

x=($12.75 * 100%) / $75=17%

Answer: the percentage increase of the cost of the jacket is 17%

Mr McKay bought b boxes of crackers for $3 each and p pounds of cheese for $4 per pound. How much did he spend in all.

Answers

In normal circumstances, you would multiply the amount of boxes by 3, and the amount of pounds by 4. So you do the same here:
3b + 4p
