Two sides of a triangle are 15 mm and 10 mm. The perimeter of the triangle is 35 mm. What's the third side?

Answers

35mm-10mm-15mm=10mm
The third side is therefore 10mm in length

( $x^(2)$ -3x=2)-(3 $x^(2)$ -5x-1)

Answers

(x^2-3x+2)-1(3x^2-5x-1)=
x^2-3x+2-3x^2+5x+1=
x^2-3x^2-3x+5x+2+1=
-2x^2+2x+3

(x² - 3x + 2) - (3x² - 5x - 1)

This problem can be split up into like terms. So, all of the terms containing x² would be put together, the terms containing just one x would be put together, and the terms without x's would be put together.

(x² - 3x²) = -2x²

(-3x - -5x) Simplify the double negative
(-3x + 5x) = 2x

(2 - -1) Simplify the double negative
(2 + 1) = 3

So, when you put those all together you get -2x² + 2x + 3.

A cube with side length m has a volume of 343 cubic centimeters. The following equation shows the volume of the cube.m^3 = 343m

What is the side length of the cube in centimeters?

Answers

The side length of the cube in centimeters is equal to 7.

Given the following data:

Volume of cube = 343 cubic centimeters.

To calculate the side length of the cube in centimeters:

How to calculate the volume of a cube.

Mathematically, the volume of a cube is given by the following formula:

$Volume = m^3$

Where:

m is the length of sides of the cube.

Substituting the given parameters into the formula, we have;

$343 = m^3\n\n$

Taking the cubic root of both sides, we have:

$m=\sqrt[3]{343}$

m = 7 centimeters.

Answer:

7 cm

Step-by-step explanation:

Given : A cube with side length m has a volume of 343 cubic centimeters.

To Find: What is the side length of the cube in centimeters?

Solution:

Volume of cube = $Side^3$

The side of the cube is m

So, Volume of cube of m = $m^3$

Since the volume of cube is 343 cubic centimeters

So, $m^3=343$

$m=\sqrt[3]{343}$

$m=7$

Hence the length of the cube is 7 cm.

Whats the mean, media, maximum,minimum,mode and range of 1,2,1,3,4

Answers

First put the numbers in order least to greatest.
(1,1,2,3,4)
The mean is the average of the group of numbers.
Too find it you add all the numbers up and divide it by how many numbers there are.
In this case it would be 11 divided by 5 so the mean would be $2 (1)/(5)$

Median is just another word for middle. After putting the numbers in order, the number in the center of the group is the median, in this case it would be 2.

The maximum would just be the largest number which is self explantory (4)

The minimum would be the lowest number (1)

I was taught to see mode as the word "most". All you do is see which number occurs the most. If all the numbers only occur once, your answer would be "No mode"

It is that simple! The Range is the difference between the lowest and highest number. So all you have to do is subtract the maximum by the minimum. In this case it would be 4-1 = 3
