Answer:no
Step-by-step explanation:
The circumference and radius are different
Answer:
3 in
Step-by-step explanation:
Sum of all sides of ∆ = perimeter
Given that it has a perimeter of 13 in, and the following sides: (x - 5) in, x/2 in, and 6 in, therefore:
Solve to find the value of x
Multiply both sides by 2
Subtract 2 from both sides
Divide both sides by 3
The shortest side = (x - 5) in
Plug in the value of x
= (8 - 5) in
= 3 in
Answer:
A) 1/45
B) 1/60
Step-by-step explanation:
<u>Part A</u>
The actual car has a length to width ratio of ...
length/width = (570 cm)/(180 cm) = 57/18 = 3 1/6
The rectangle on the screen has a length to width ratio of ...
length/width = (13 cm)/(4 cm) = 3 1/4
Relative to its width, the screen rectangle is longer than necessary for a model of the car. So, the scale factor will be determined by the width of the car relative to the width of the screen model.
For a model width of 4 cm, the scale factor is ...
model/life-size = (4 cm)/(180 cm) = 1/45
__
<u>Part B</u>
For a model width of 3 cm, the scale factor is ...
model/life-size = (3 cm)/(180 cm) = 1/60
x = [-(-6) +/- sqrt((-6)^2 - 4*1 * 8))] / 2
= (6 + sqrt4) / 2 , ( 6 - sqrt4)/2
= 4 , 2
To start off scaling is another way of saying resizing the numbers --
Example: "1" on paper means "10" in real life --
To predict a product of a number/fraction using scaling, you would compare the size of a product on the basis of the size of the other.
Most scaling is used in maps or something to do with rulers
I hope this helps!!
