two sides of a triangle measure to 20cm and 30cm. Which of the following could be measure by the third side

gizmo_the_mogwai [7]

Answer: With no choices given here, here are a few possibilities.

If it is not a right triangle, the third side could be any number less than 50 cm

If it is a right triangle, the third side could be the hypotenuse, which would be 10√13 or about 36.05 cm.

If 30cm is the hypotenuse, the other side would be 10√5 or about 22.36 cm

Step-by-step explanation: If the two given sides add up to 50, they flatten out to a straight line, equal to the third side, so it is no longer a triangle. The third side must be less than the sum of the other two sides.

We can use the Pythagorean Theorem a² + b² = c² to calculate the lengths of the sides of a right triangle.

For example

20² + 30² = c²

400 + 900 = c²

1300 = c²

√1300 = √(100)(13) = √c²

10√13 = c ≈ 36.05

Which number has a cube root between 7 and 8

lubasha [3.4K]

Step-by-step explanation:

Here ,There are no options given to choose which number is a cube root between 7 & 8 . So below provided answer is way to choose which numbers have cube root between 7 & 8 .

Here , We have to find that Which number has a cube root between 7 and 8 . Let's find out :

We know that ,

$\sqrt[3]{343} = 7\\\sqrt[3]{512} = 8$

So , the number which have cube root between 7 & 8 will surely lie in between of 343 & 512 . Suppose the numbers which which have cube root between 7 & 8 are $x_1,x_2,x_3,....,x_n$ , So these numbers lie between 7 & 8 i.e.

⇒ $343$

Therefore, all the numbers which lies between 343 and 512 or $343$ , have a cube root between 7 & 8 .

You are ordering softballs for two softball leagues. The Pony Leagues uses an 11-inch softball prices at $2.75. The Junior Leagu

Zigmanuir [339]

Answer:

I have ordered 30 softballs of 11-inch and 50 soft balls of 12-inch.

Step-by-step explanation:

Let the number of 11-inch softball be 'x'.

Let the number of 12-inch softball be 'y'.

Given:

Total number of soft balls = 80

Now we know that.

Total number of soft balls is equal to sum of the number of 11-inch softball and the number of 12-inch softball.

framing in equation form we get;

$x+y=80 \ \ \ \ equation \ 1$

Also Given:

Price of 11- inch softball = $2.75

Price of 12-inch softball = $3.25

Total Bill = $245

Now we know that;

Total bill of soft balls is equal to sum of Price of 11- inch softball multiplied by the number of 11-inch softball and Price of 12- inch softball the number of 12-inch softball.

framing in equation form we get;

$2.75x+3.25y = 245 \ \ \ \ equation \ 2$
