1 foot = 12 inches
42 feet = (42 x 12) = 504
The factor of (6 inches / 42 feet) is (6 inches / 504 inches) = 1 / 84 .
The scale factor is not in inches. It's a factor, and has no units.
A 1-ft model would represent a real 84 feet.
A 1-meter model would represent a real 84 meters.
A 1-yard model would represent a real 84 yards.
Answer: 50,001²-49,999²=0,2.
Step-by-step explanation:
First, we can convert feet to inches 1 foot=12 inches 7 feet=84 inches Next, we find out inches per hour 84 inches/27 1/2 hours ----------- -------------- 27 1/2 27 1/2 =3.054 inches/hour
Answer:
5438.5
Step-by-step explanation:
To complete this equation, we must use the order of operations also known as PEMDAS.
For the case of this problem, we start by multiplying or dividing numbers before adding or subtracting numbers.
First let's start on the left:
100 x 54 + 77 ÷ 2
5,400 + 77 ÷ 2
5,400 + 38.5
5438.5
I hope this helps! Just remember to always add or subtract number last and start on the left, so that you don't get confused.
y=mx+b is the equation of a line;
m=slope , b= y-intercept
m=4 ; so we have : y=4x+b
We are give a set of points which it passes through, we can simply plug them in:
-2 = 4(3)+b (3 is the x and -2 is the y)
We get -2 = 12 +b .... -14=b
our final equation is : y=4x-14
