Make 37.5% into decimal form : Since it is being marked up, add 100% = 1.375
1.375 x 80
1.375
x 80
_________
0000
+11000
_________
110.000
80 marked up by 37.5% is 110.
3. 3/10 and 5/10 4. 12/20 and 15/20 5.4/8 and 7/8 6. 8/12 and 5/12 7. 3/12 and 2/12. 8. 1/2>2/5 9.1/2 = 3/6 10. 3/4<5/6 11. 6/10=3/5
Answer:

</h3>
Step-by-step explanation:
The SI unit of work is Joule.
Further more explanation:
▪️
⇒Work done by a force acting on a body is defined as the product of force and displacement of the body in the direction of the force.
▪️
⇒The system of units which is agreed by the international convention of scientists held in France in 1960 is called SI unit.
▪️
⇒One joule is the amount of work done when one Newton force displaces a body through one metre in its own direction.

Answer:
503.47
Step-by-step explanation:
the third one
x^2 + 2x + 8
First, we'll try using the AC method.
(Because the degree of the quadratic is 2, there are two solutions.)
We cannot split the term using the AC method.
We'll instead use the quadratic formula.

Plug in values.
(-2 +/- √4 - 32)/2
(-2 +/- √-28)/2
(-2 +/- i√28)/2
(-2 +/- 2i√7)/2
(-1 +/- i√7)
<h3>x = (-1 + i√7)</h3><h3>x = (-1 - i√7)</h3><h3>The two values of x are found.</h3>
