Paulette wrote the equation below to show f, the amount of framing she needs for a square frame with a side length of s centimet

tatyana61 [14]

Answer: 61.2 centimeters

Step-by-step explanation:

Since the equation given to show the amount of framing that she needs for a square frame with a side length of s centimeters is:

f = 4s

Therefore, the number of centimeters of framing needed by Paulette for a square frame that has a side length of 15.3 centimeters will be:

f = 4s

f = 4 × 15.3

f = 61.2 centimeters

On a set of blueprints for a new home, the contractor has established a scale of 0.5in : 10 ft. What are the dimensions on the b

Kipish [7]

Answer:

The dimensions on the blueprints are 0.9 inches and 0.8 inches

Step-by-step explanation:

* Lets explain the relation between the drawing dimensions and

the real dimensions

- A scale drawing make a real object with accurate sizes reduced

or enlarged by a certain amount called the scale

- Ex: If the scale drawing is 1 : 10, so anything drawn with the size of

1 have a size of 10 in the real so a measurement of 15 cm on the

drawing will be 150 cm on the real

- In a scale drawing, all dimensions have been reduced by the same

proportion

* Lets solve the problem

- On a set of blueprints for a new home, the contractor has

established a scale of 0.5 in : 10 ft

∵ The drawing scale ratio must be in same unit

∴ Change the feet to inch

∵ 1 foot = 12 inches

∴ 10 feet = 10 × 12 = 120 inches

∴ The scale is 0.5 inches : 120 inches

- Simplify the scale by multiply it by 2

∴ The scale is 1 in : 240 in

- Lets find the dimensions on the blueprints

∵ The real dimensions are 18 feet and 16 feet

- Change the feet to inches

∴ 18 feet = 18 × 12 = 216 inches

∵ 16 feet = 16 × 12 = 192 inches

∵ The scale is 1 : 240

∴ 1/240 = x/216 ⇒ use cross multiplication

∴ 240 x = 216 divide both sides by 240

∴ x = 0.9 inch

∵ The scale is 1 : 240

∴ 1/240 = y/192 ⇒ use cross multiplication

∴ 240 y = 192 divide both sides by 240

∴ y = 0.8 inch

* The dimensions on the blueprints are 0.9 inches and 0.8 inches

What is the image of the point (8,4) after a rotation of 90° counterclockwise about the origin?<br>

Alenkinab [10]

<h3>Answer: (-4, 8)</h3>

=========================================================

Explanation:

The 90 degree counterclockwise rotation rule we use is

$(x,y) \to (-y,x)$

the x and y coordinates swap places, and we change the sign of the first coordinate after the swap.

After using that rotation rule, we would go from (8,4) to (-4, 8) which is the final answer.

----------------

Extra info (optional section):

Define the following three points

A = (0,0)

B = (8,4)

C = (-4,8)

Use the slope formula to find that AB and AC have slopes of 1/2 and -2 in that order.

Those slopes multiply to -1, since (1/2)*(-2) = -1. This is a property of any two perpendicular lines as long as neither line is vertical and neither is horizontal. So this is sufficient to prove that the lines are perpendicular. This further means that a 90 degree rotation has taken place.
