If the area of triangle is 1200 sq m and its length is 60 m , find the breadth .

Answers

Answer:

20 m

Step-by-step explanation:

The area of a triangle is 120 sq m

The length is 60 m

We are required to find the breadth

Therefore to find the breadth of the traingle the formular below will be applied

Area= length × breadth

120= 60 × breadth

Breadth= 120/60

= 20 m

Hence the breadth of the traingle is 20 m

answer this equation-3x+2<8

Answers

Answer:

x > -2

Step-by-step explanation:

-3x+2<8

Subtract 2 from each side

-3x+2-2<8-2

-3x<6

Divide each side by -3, remembering to flip the inequality

-3x/-3 > 6/-3

x > -2

Hey there!☺

[tex]Answer:\boxed{x>-2}[/tex]

[tex]Explanation:[/tex]

[tex]-3x+2<8[/tex]

Let's subtract 2 from both sides of the inequality.

[tex]-3x+2-2<8-2\\-3x<6[/tex]

Now divide both sides by -3.

[tex]\frac{-3x}{-3}<\frac{6}{-3}[/tex]

Simplify 6/-3. Also remember that dividing a positive with a negative will give us a negative.

Approximately how many times greater is 2.3x10^-4 than 1.15x10^-8?

Answers

Answer:

2.3 ×  is 20,000 times greater than 1.15 ×

Step-by-step explanation:

Given as :

The first number= x = 2.3 ×

The second number= y = 1.15 ×

Let The first number is z times greater than second number

i.e x = z × y

Or, z =

Or, z =

Or, z = 2 ×

∴  z = 20,000

So,The first number is 20,000 times greater than second number

Hence, 2.3 ×  is 20,000 times greater than 1.15 ×

For which values of a the system has at least one solution: x≤7 x≥a urgent pls help now

Answers

Answer:

We have the system:

x ≤ 7

x ≥ a

Now we want to find the possible values of a such that the system has, at least, one solution.

First, we should look at the value of a where the system has only one solution:

We can write the 2 sets as:

a ≤ x

x ≥ 7

So, writing both together:

a ≤ x ≤ 7

if a is larger than 7, we do not have solutions.

then a = 7 gives:

7 ≤ x ≤ 7

Here the only solution is 7.

Now, if a is smaller than 7, for example 5, we have:

5 ≤ x ≤ 7

Now x can take different values, so we have a lot of solutions.

Then the restrictions for a, such that the system has at least one solution, is:

a ≤ 7.

What is the value of x?

Answer:

  The train is not moving

Step-by-step explanation:
