When a number is decreased by 19% the result is 66 what is the original number to
dybincka [34]

Answer:

<em>The original number is x = 66 .19</em>

Step-by-step explanation:

<em>Let 'x' be the number</em>

Given data a number is decreased by 19% the result is 66

x - 19% = 66

x-0.19 = 66

Adding '0.19' on both sides , we get

x - 0.19 +0.19 = 66 +0.19

x = 66 .19

<em>The original number is x = 66 .19</em>

An aircraft jet engine has a thrust of I80N. What impulse is produced<br> in 30 S?
neonofarm [45]

The impulse that was produced by this aircraft jet engine is 5,400 Ns.

<u>Given the following data:</u>

  • Thrust = 180 Newton.
  • Time = 30 seconds.

To determine the impulse that was produced by this aircraft jet engine:

<h3>How to calculate impulse.</h3>

Mathematically, impulse is given by this formula:

I = Ft

<u>Where:</u>

  • F is the force or thrust.
  • t is the time measured in seconds.

Substituting the given parameters into the formula, we have;

I = 180 \times 30

Impulse, I = 5,400 Ns.

Question: 7 After seven years, the age of father will be 4 times the age of his daughter. If x stands for the present age of the
enot [183]

Answer:

Here is your answer

Step-by-step explanation:

Step -1: Forming equations.

                  Let, present age of son = x

                  And, present age of father = 3x+3

                  3 years later, age of son = x+3

                  age of father = 3x+3+3=3x+6                                  ...(i)

                  According to the given condition, age of father = 10+2(x+3)        ...(ii)

Step -2: Solving for x

                  From (i) and (ii)

                  ∴3x+6=10+2(x+3)

                  ⇒3x+6=10+2x+6

                  ⇒3x−2x=10+6−6

                  ⇒x=10

                  ∴Present age of son = 10 

                  and present age of father = 3x+3=3×10+3=33

Hence, son’s present age is 10 years and father’s
