The required distance on the number line is  -0.75 to 1.25 i.e. 2 units.

Given that,
To add using a number line.​ −3 / 4 + 1 1 / 4 ​Drag and drop the word SUM to the correct value on the number line.

What is a number line?

A number line is defined as the number marked on the line calibrated into an equal number of units. For example -1, 0, 1, and so on.

What is Distance?

Distance is defined as the difference of numbers between two numbers.

Here,
-3 / 4 = - 0.75
Pin -0.75 on the number line will lie right of the -1

1 1 /4 = 1.25
Pin 1.25 on the number line it will lie right of 1.

Now from -0.75 to 1.25, the distance is given as
= 1.25 - (-0.75)

= 2.00

Thus, the required distance on the number line is  -0.75 to 1.25 i.e. 2 units.

Answer:

so length of sides is 6 .2 m ( other side will also be 6.2 m)

base = 3.2 cm

Step-by-step explanation:

solution

let the length of sides of isosceles triangle is = x

as two sides of  of isosceles triangle are equal

let the length of the side be x

so length of side = x

base  = x -3 ( as it is 3 m smaller in length )

according to formula of perimeter of isosceles triangle

perimeter = 2 (side) + Base

adding the values  

15.6  = 2 (x) + x-3

15.6 = 2x +x -3

15.6 = 3x-3

15.6 = 3( x-1) taking 3 common

dividing both sides by 3

15.6/3 = 3(x-1)/3

5.2  =x-1

or x -1 = 5.2

adding 1 from both sides

x-1 +1 = 5.2 +1

x = 6.2

so length of sides is 6 .2 m ( other side will also be 6.2 m)

base = x-3 = 6.2-3 = 3.2 m

Answer:

6 .2 m ,6.3 m, 3.2 m

Step-by-step explanation:

Ratio of areas of similar triangles is 9 : 25.

Solution:

Given data:

Ratio of sides of two similar triangles = 3 : 5

To find the ratio of areas of the triangles:

We know that,

In two triangles are similar, then the ratio of their area is equal to the square of the ratio of their sides.

Ratio of areas of similar triangles is 9 : 25.

Calculating 36 x 3/4 gives you the result of 27.

To find 36 multiplied by 3/4 mentally, you can follow these steps:

1. Simplify the fraction: 3/4 can be simplified by dividing both the numerator and the denominator by their greatest common divisor, which is 1 in this case.

This simplification leaves us with 3/4 as the fraction.

2. Convert the whole number to a fraction:

Since 36 is a whole number, we can rewrite it as a fraction with a denominator of 1. So, 36 can be expressed as 36/1.

3. Multiply the numerators: Multiply the numerators of the fractions together: 36 x 3 = 108.

4. Multiply the denominators: Multiply the denominators of the fractions together: 1 x 4 = 4.

5. Write the result as a fraction: Take the product of the numerators and write it over the product of the denominators: 108/4.

6. Simplify the fraction if possible: Divide both the numerator and the denominator of the fraction by their greatest common divisor, which is 4 in this case. Simplifying the fraction gives us 27/1 or simply 27.

Therefore, mentally calculating 36 x 3/4 gives you the result of 27.
