You increase the size of a page by 50% then you decrease it by 50% what is the size of the page now
Artyom0805 [142]

Answer:

75% of the original paper’s size.

Step-by-step explanation:

Let’s say that the original size was 10 inches.

You then increase it by 50%. It is now 15 inches.

Now, you decrease it by 50%. 50% of 15 is 7.5. So, the paper is now 7.5 inches.

7.5 inches is 75% of the original paper size.

I hope I helped!

When Kevin bought a new bike ramp, he borrowed $1,200 at a rate of 18% for 9 months. How much interest did he pay?
AURORKA [14]

We would apply the formula for determining simple interest which is expressed as

I = PRT/100

I is the interest

P is the principal or initial amount

R = interest rate

T = time in years

From the information given,

P = 1200

r = 18

Since there are 12 months in a year,

T = 9/12 = 0.75

Thus,

I = (1200 x 18 x 0.75)/100

Interest = $162

  • ➣ Given two paris are linear pairs

  • ➣ Linear :- Having the form of a line; straight or roughly straight; following a direct course.

\large\underline{  \boxed{ \sf{✛\: Assumptions\:✛ }}}

  • ➣ let given two angles be p and q that is
  • ➣ angle p is 3x-4
  • ➣ angle q is 3x-8
  • ➣ we have to find "x" in the given expressions

\large\underline{  \boxed{ \sf{✰\: let's\:solve }}}

\rm\angle \: p +  \angle \: q = 180 \degree \\

★ Substituting values

\rm { \pink➾ \:( 3x  - 4) + (3x - 8) = 180} \\ \rm { \pink➾}arranging \: and \: solving \: like \: terms \\ \rm { \pink➾ \: 3x + 3x - 4 - 8 = 180} \\ \rm { \pink➾ \: 6x - 12 = 180} \\ \rm  { \pink➾6x = 180  + 12}
