What is the unitary method?

The unitarymethod is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value. The unitary method is a method by which we find the value of a single unit from the value of multiple devices and the value of more than one unit from the value of a single unit.

We are given the sum of 130 cm and 50 mm. in meters

130 cm = 130 / 100

= 1,3m

50 mm = 50 / 1000

= 0,05m

Therefore, the addition is;

1.3 + 0.05m = 1.35m

6 numbres

mean=(sum of all numbers)/(how many numbers)

mean=119
119=(102+122+106+113+107+x)/6
119=(550+x)/6
times 6 both sides
714=550+x

The points (4,t) and (5,-
4) fall on a line with a slope of
-
7. What is the value of t?
t=

Answers

Answer:

t = -3

Step-by-step explanation:

To answer this problem, first you have to know how to calculate the slope of a line. Since we know that y1-y2/x1-x2 is the equation to calculate slope, we are ready to tackle this problem.

Because y1 is t, y2 is 4, x1 is 4, and x2 is 5, we can now plug this in to our equation. The equation becomes t-4/4-5. And because we know the slope is 7, the equation is now (t-4)/(4-5)=7. If you solve this equation, you will get that t=-3

Explain why a change from 20 to 40 is a 100% increase, but a change from 40 to 20 is a 50% decrease.Increasing 20 to 40 is the same as increasing 20 by c. So, it is a 100% increase. Decreasing 40 to 20 is the same as decreasing 40 by one-half of c. So, it is a 50% decrease.
I don't understand how to fill in the blanks.

Answers

I believe the answer you are looking for is:

Increasing 20 to 40 is the same as increasing 20 by 20 (or itself), so it is a 100% increase. Decreasing 40 to 20 is the same as decreasing 40 by 1/2 or by 20. So it is a 50% increase.

Basically, when going from 20 to 40, the number is being doubled, and when youre going from 40 to 20 you are cutting the number in half.

Answer:

The first blank is 20 and the second is actually 40

4% of ____ days is 56 days

Answers

4%=4/100
4/100=56/x
(4)(14)=56, (100)(14)=1400)
4/100=56/1400
therefore 4% of 1400 days is 56 days
:)

We know that 4% = 56 days
To work out 1% we can divide the number of days by 4, as 4% / 4 = 1%
56 / 4 = 14
1% = 14 days

What we want to find next is what 100% is
From 1%, we multiply by 100 to get 100%, we do the same to the number of days
14 x 100 = 1400 days
