Compatible numbers

Step-by-step explanation:

Compatible numbers are pairs of numbers that are easy to add, subtract, multiply, or divide mentally. When using estimation to approximate a calculation, replace actual numbers with compatible numbers. ... An estimate of 513 + 299 is found by mentally calculating 500 + 300 = 800.

A parachutist descends 44 feet in 4 seconds. Express the rate of the parachutist's change in height as a unit rate.
Montano1993 [528]

The unit rate of the parachutist change in height is 11 feet per second.

   • In Mathematics, Unitary method is a technique for solving a question by first finding the value of a single unit and then finding the required value by multiplying the number by value of single unit .

   • We use unitary method to find the ratio of one thing with respect to other thing.

   • There are two types of unitary method one is Direct Variation and the other is Inverse variation.

We have the rate of descend as 44 feet in 4 sec.

So, in 1 second it will be = 44 / 4 = 11 feet.

Which is the unit rate.

Therefore, the unit rate of descend for the parachutist is 11 feet per second.

You don’t even have to give the answer just please explain
jenyasd209 [6]

Answer:

1/2

Step-by-step explanation:

remember that the formula for the slope of a line is

m=\frac{y_{2}-y_{1}  }{x_{2}-x_{1}  }

where m is the slope, and the x and y variables are the x-y coordinates of two points. Choose two points on the line:

Point 1 : (-1,3) and Point 2 : (1,4)

Plug in your values:

m=\frac{4-3}{1-(-1)}

m=\frac{1}{2} \\

So the slope of this line is 1/2 !
