What is 20% of 40, work it out

Darina [25.2K]

Hey there

Answer:

20% of 40 is 8 .

Step-by-step explanation:

In this question we are given a number that is 40 . And we have asked to find 20% of it .

Solution : -

$\longmapsto \qquad \: \: 20\% \times 40$

We know that ,

Percent ( % ) represent 1/100

So ,

 $\longmapsto \qquad \: \: ( 20 \times \dfrac{1}{100}) \times 40$ 

or ,

 $\longmapsto \qquad \: \: \dfrac{20}{100} \times 40$ 

Now cancelling zero :

$\longmapsto \qquad \: \: \dfrac{2 \cancel{0}}{1 \cancel{0} \cancel{0}} \times 4 \cancel{0}$

We get ,

$\longmapsto \qquad \: \: 2 \times 4$

$\longmapsto \qquad \: \: \blue{\underline{\boxed{\frak{8}}}} \quad \bigstar$

Therefore , 20% of 40 is 8 .

The sum of x,y and z is 952. if z is 40% less than the sum of x,y, then what is the value of z?

julsineya [31]

The answer is z is about equal to 380.4
Here is my math
952/3=317*2=643/100=6.43*40=253.6
643-253.6=380.4

Answer:

see explanation

Step-by-step explanation:

the exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.

∠ 4 , ∠ 5 , ∠ 6 are exterior angles of the triangle

-------------------------------------------

(14)

∠ 1 and ∠ 4 are adjacent angles and sum to 180° , then

∠ 1 = 180° - 58° = 122°

∠ 2 + ∠ 3 = ∠ 4

∠ 2 + 32° = 58° ( subtract 32° from both sides )

∠ 2 = 26°

∠ 5 = ∠ 1 + ∠ 3 = 122° + 32° = 154°

∠ 6 = ∠ 1 + ∠ 2 = 122° + 26° = 148°

(15)

∠ 4 = ∠ 2 + ∠ 3 = 11° + 143° = 154°

∠ 1 = 180° - ∠ 4 = 180° - 154° = 26°

∠ 5 = ∠ 1 + ∠ 3 = 26° + 143° = 169°

∠ 6 = ∠ 1 + ∠ 2 = 26° + 11° = 37°

Why is the distributive property so important

vlabodo [156]

Answer:
When you distribute something, you are dividing it into parts. In math, the distributive property helps simplify difficult problems because it breaks down expressions into the sum or difference of two numbers.

Good luck !
