<u>Given</u><u> </u><u>Information</u><u> </u><u>:</u><u>-</u>

⠀

  • Each exterior angle of a regular polygon has a measure of 40°

⠀

<u>To</u><u> </u><u>Find</u><u> </u><u>:</u><u>-</u>

⠀

  • The number of sides of the polygon

⠀

<u>Formula</u><u> </u><u>Used</u><u> </u><u>:</u><u>-</u>

⠀

\qquad \star \:  \underline{ \boxed{ \green{  \sf No.~of~sides = \dfrac{360^ \circ}{exterior ~angle}}}} \:  \star

⠀

<u>Solution</u><u> </u><u>:</u><u>-</u>

⠀

Using the formula,

⠀

\sf \dashrightarrow No. ~of~sides= \dfrac{360}{40}  \\  \\  \\ \sf \dashrightarrow No. ~of~sides= \frac{ \cancel{360}}{ \cancel{40} } \\  \\  \\  \sf \dashrightarrow No. ~of~sides= \underline{ \boxed{ \blue { \frak{9}}}} \:  \star

⠀

Thus, the polygon is a nonagon, and hence has 9 sides.

⠀

\underline{\rule{227pt}{2pt}} \\  \\

A scale has a percent error of 7%. The scale reads the mass of a book as 450g. Which statement describes what the actual mass of
ozzi

Answer:

The actual mass of the book is between  481 . 5 g and 418 . 5 g.

Step-by-step explanation:

The mass of the book on the scale = 450 g

The percentage error in the scale = 7%

So, the actual mass of the book is 450 g ± 7%

Now, 7 % of  the mass 450 g = \frac{7}{100}  \times 450 = 31.5

⇒ 7% of 450 g = 31.5 g

Now, the Actual mass of the book =  450 g ± 31.5 g

450 g + 31.5 g   = 481 . 5 g

450 g - 31.5 g    = 418 . 5 g

Hence the actual mass of the book is between  481 . 5 g and 418 . 5 g.

Janelle has a 12 ounce can of soft drink. She drink 3/5 of the soft drink. How many ounces of soft drink are left in tbe can?
ivann1987 [24]

Answer:  4.8 ounces

Step-by-step explanation:

In total there are 12 ounces. If she drinks 3/5 of 12 you multiply 3/5 by 12.

3/5 * 12 would be equal to 3/5 * 12/1 which is 36/5. You have found how much she has drank. 36/5 is also equal to 7.2 ounces. Subtract 7.2 form 12 and you get 4.8 ounces.

Hope this helped!

A car of 1000 kg starts to move from rest and travels a distance of 150 m in 10 second. How much force is needed?​
allsm [11]
  • Initial velocity=u=0m/s
  • Distance=s=150m
  • Time=t=10s
  • Acceleration=a

Using second equation of kinematics

\\ \sf\longmapsto s=ut+\dfrac{1}{2}at^2

\\ \sf\longmapsto 150=0(10)+\dfrac{1}{2}a(10)^2

\\ \sf\longmapsto 150=\dfrac{1}{2}\times 100a

\\ \sf\longmapsto 50a=150

\\ \sf\longmapsto a=\dfrac{150}{50}

\\ \sf\longmapsto a=3m/s^2

  • Mass=m=1000kg
  • Force=F

Using newtons second law

\\ \sf\longmapsto F=ma

\\ \sf\longmapsto F=1000(3)

\\ \sf\longmapsto F=3000N
