1 answer:
Troyanec [42]3 years ago
7 0

Answer:

Lengths all the three sides are 9m, 18m and 12m

Step-by-step explanation:

Let us assume the length of the second side  to be x m

According to the question:

first side = 2x

third side = x + 3

Applying the formula of perimeter:

Perimeter = length + breadth + height

39 = 2x + x + (x + 3)

39 = 2x + x + x + 3

39 = 4x + 3

39 - 3 = 4x

4x = 36

x = \frac{36}{4}

x = 9

length of the first side (x) = 9 m

length of the second side (2x) =2 × 9 =18 m

length of the third side (x + 3) = 9 + 3 = 12 m

∴ lengths all the three sides are 9m, 18m and 12m

What’s the volume of 4.3ft 5.2ft cone round to nearest hundredth
Vika [28.1K]

Answer:

Pick the best solution.

Step-by-step explanation:

Volume of a cone is V = ⅓πr²h

If cone diameter is 4.3

V = ⅓π(4.3/2)²(5.2) = 25.17148... ≈ 25.17 ft³

If cone radius is 4.3

V = ⅓π(4.3)²(5.2) = 100.685950... ≈ 100.69 ft³

If cone diameter is 5.2

V = ⅓π(5.2/2)²(4.3) = 30.439938... ≈ 30.44 ft³

If cone radius is 5.2

V = ⅓π(5.2)²(4.3) = 121.75975... ≈ 121.76 ft³

Three different golfers played a different number of holes today. Rory played 9 holes and had a total of 42 strokes. Jordan play
stiv31 [10]
Okay so for each person we're pretty much gonna have to find the value of strokes over holes.
Rory: 42 strokes per 9 holes
Jordan: 79 strokes per 18 holes
Ricky: 123 strokes per 27 holes

Now, we can do the division for each person and round. But first, I'll say stokes per hole is s/h. Just feed each number into a calculator like this: <em>per </em>means divide.

Rory: 4.66667 s/h
Jordan: 4.38889 s/h
Ricky: 4.55556 s/h
Well, Jordan had the lowest number of strokes per hole since his value is the smallest.

Answer: Jordan

Samantha is making soup. to make the broth, she combines 2/5 cup of vegetable stock and 2/3 cup of chicken soup stock. Boiling
iogann1982 [59]
First,you do,2/5+2/3,but since you will need a common denominator,you will find the least common denominator for 5 and 3.The LCD(Least Common Denominator) will be 15 since both 5 and 3 could go in 15.Now,the equation looks like this: 2/15+2/15 since whatever you do to the bottom numbers,you NEED to do to the top numbers:2 and 2.Now you will need to do,2x3,since 5x3=15 and the answer to 2x3=6 then you do 2x5,since 3x5=15 the answer is 10 now the equation looks like this:6/15+10/15 now you add them together,and the answer will be 16/15 and if you want the answer to be a mixed number,it would look like this: 1 1/15. Hope this helps!
