Sides Of A Triangle Are Of The Ratio 2:3:4. If The Perimeter Of The Triangle Is 90 Cm, What Is The Area
Answer 2

The area of a triangle with ratio of 2:3:4 and a perimeter of 90 centimeter is 290. 47 centimetre squared.

What is perimeter of a triangle?

The perimeter of a triangle is the sum of the whole sides of the triangle.

Therefore, the perimeter is given as follows:

perimeter = 90 cm

Hence, the sides can found as follows:

2 / 9 × 90 = 20 cm

3 / 9 × 90 = 30 cm

4 / 9 × 90 = 40 cm

Area = √s(s-a)(s-b)(s-c)

where

a, b and c are the sidess = semi perimeter

Hence,

s = 90 / 2 = 45

a = 20 cm

b = 30 cm

c = 40 cm

Therefore,

area of the triangle = √45(45 - 20)(45 - 30)(45 - 40)

area of the triangle =√45(25)(15)(5)

area of the triangle = √84375

area of the triangle = 290.473750966

area of the triangle = 290. 47 cm²

Max bought two items that were both on sale one item was 10% off and one item was 20% off max says that he saved 15% althogether is he correct?

Answers

Answer:

yes

Step-by-step explanation:

No, Max was wrong about his claim. Max saved 30% altogether.

Let the first item be (a) Let the second item be (b)

Discount Offer

a = 10%b = 20%

For the two items, the total discount that Max saved was

= (10 + 20)%

= 30%.

Averagely, if we are to determine the average discount for each of the items, we have:

= 30% ÷ 2

= 15%

So, on each item, Max saved 15% on average.

Therefore, we can conclude that Max saved 30% altogether for the two items.

Jin has 34 feet of garden fence. He wants the shape of his garden to be a rectangle 5 feet wide.
Which should be the length of Jin's garden?
O A 42 feet
OB 24 feet
O c. 12 feet
D. 6 feet

Answers

C) 12 feet
Form equation 34=2x+10 (2 unknown lengths which are x and two 5 feet widths. They add up to his 34 feet of fence total).
Subtract 10 from both sides to whet 24=2x.
Divide both sides by 2 to isolate x and get the length is 12 feet.

E varies directly with G. When G is 6, E is 10. Find the value of G when E is 18.

Answers

Answer:

  10.8

Step-by-step explanation:

E has increased by a factor of 18/10 = 1.8, so G will increase by that factor. The corresponding value of G is ...

  6 × 1.8 = 10.8 = G

__

If you like, you can write an equation relating G to E:

  E = kG

  10 = k(6)

  k = 10/6 = 5/3

Now for E = 18, we have ...

  18 = (5/3)G

  18(3/5) = G = 10.8
