Faction Equivalent demcimal for 2.46
Paul [167]

Here is you're answer:

In order to find the answer you have to switch all the options into decimals to see which one is equivalent to 2.46!

  • \frac{246}{1000}
  • \frac{246}{1000} = 246 \div 1000 = 0.246
  • 2\frac{46}{1000}
  • 2\frac{46}{1000} = \frac{1023}{500} = 1023 \div 500 = 2.046
  • 2 \frac{23}{50} = \frac{123}{50} = 123 \div 50=2.46 <-- You're answer.
  • \frac{223}{500} = 223 \div 500 = 0.446

Therefore you're answer is option C "2 23/50." Remember when wanting to find the decimal divide the numerator by the denominator after you convert the mixed number (if it's a mixed number) into a improper fraction!

Hope this helps!

2.2.3 Quiz: Angle Theorems
serious [3.7K]

The value of y is 40 degree , Option B is the correct answer.

<h3>What is Angle Sum Property ?</h3>

According to angle sum property, the sum of all angles of a triangle is equal to 180 degree.

It is given in the question a triangle  , here

the angles given are 2y , y+10 , 50 degree

From the property ,

2y + y +  10 +50 = 180

3y +60 = 180

3y = 120

y = 40 degree

Therefore The value of y is 40 degree , Option B is the correct answer.

Please Answer <br><br> This is due by tomorrow night and I need help
labwork [276]

Answer:

AY = 16

IY = 9

FG = 30

PA = 24

Step-by-step explanation:

<em>The </em><em>centroid </em><em>of the triangle </em><em>divides each median</em><em> at the ratio </em><em>1: 2</em><em> from </em><em>the base</em>

Let us solve the problem

In Δ AFT

∵ Y is the centroid

∵ AP, TI, and FG are medians

→ By using the rule above

∴ Y divides AP at ratio 1: 2 from the base FT

∴ AY = 2 YP

∵ YP = 8

∴ AY = 2(8)

∴ AY = 16

∵ PA = AY + YP

∴ AP = 16 + 8

∴ AP = 24

∵ Y divides TI at ratio 1: 2 from the base FA

∴ TY = 2 IY

∵ TY = 18

∴ 18 = 2

→ Divide both sides by 2

∴ 9 = IY

∴ IY = 9

∵ Y divides FG at ratio 1:2 from the base AT

∴ FY = 2 YG

∵ FY = 20

∴ 20 = 2 YG

→ Divide both sides by 2

∴ 10 = YG

∴ YG = 10

∵ FG = YG + FY

∴ FG = 10 + 20

∴ FG = 30
