Which fractions are equivalent to 40%?
Answers
All of them except 8/100 because it results 0.08 or 8%.
The rest:
2/5 = 0.4 = 40%
8/20 = 0.4 = 40%
4/10 = 0.4 = 40%
16/40 = 0.4 = 40%
8/100 doesn’t equal to 40 because it’s already over 100
2/5 x 20 = 40/100
8/20 x 5 = 40/100
4/10 x 10 = 40/100
16/40 divide by 2 = 1/5 x 20 = 20/100
So your answers are 2/5, 8/20 and 4/10

What is 10 percent of 80

The percentage increase in team sales is 44% and this can be determined by using the unitary method.
Given :
The sales increase from 90 units to 130 units.
The following steps can be used in order to determine the percentage increase in sales:
Step 1 - The unitary method can be used in order to determine the percentage increase in sales.
Step 2 - According to the given data, the team sales are 90 units which are 100%. After increasing the sales becomes 130 units.
Step 3 - So, let the percentage of 130 units be 'x'. So, the value of 'x' is:
Step 4 - So, the percentage increase in sales is:
The percentage increase in team sales is 44%.
For more information, refer to the link given below:
The sales was increased by 44.4%.
Step-by-step explanation:
- Lets do this cumulative
- 90 of 10 % = 9 which is 99
- 90 of 10 % = 9 which is 108
- 90 of 10% = 9 which is 117
- 90 of 10% = 9 which is 126
- 90 of 4 % = 3.6 which is 129.6
- 90 of 0.044% = 0.0396 which is 129.99
- This comes to nearly 44.44 to be closer there was an increase.
- Always rule 1 approximation use 50% of 90 if it is above 130.
- Down it to 40% of 90 see if the sales is lower than 130.
- It should always start with 50,40,30....10 percents.
- Alternative should be 10,1 or decimals.
- Approximation using decimals rounding up becomes simple.
and enter your answer as a decimal.

Answer:
14.13
Step-by-step explanation:
The formula for area of a circle is πr^2.
This is a semicircle which is half a circle, so the formula for area of a semicircle is (πr^2)/2
The diameter of the circle is 6, which means that the radius is 3. Since the radius of a circle is always half the diameter. (1/2*6=3)
This means we can plug the known values into our formula.
π(3)^2/2
Simplify.
9π/2
Now we plug 3.14 in for π.
9(3.14)/2
28.26/2
14.13
But for a semicircle the area is pi multiplied by radius squared divided by two
So, we do 3.14*3^2/2
Which is 14.13

The base and height of the triangle are 6 and 12 feet respectively.
What is the perimeter of a triangle ?
The perimeter of a triangle is sum of the lengths of it's sides.
According o the given question A triangle has area of 36 square feet.
Also given that the height is 6 feet more than it's base.
Assuming base of the triangle to be b.
∴ Height of the triangle (h) = (b+6).
We know area of a triangle is (1/2)×base×height.
∴ (1/2)×b×(b+6) = 36.
b² + 6b = 72.
b² + 6b - 72 = 0.
b² + 12b - 6b - 72 = 0.
b(b+12) -6(b+12) = 0.
b - 6 = 0 OR b + 12 = 0.
b = 6 OR B = -12. ( -12 is not applicable since length can't be negative )
So, The base of the triangle is 6 feet.
∴ Height is 6 + 6 = 12 feet.

Answer:
(x - 1)(x - 3)(x + 2).
Step-by-step explanation:
f(1) = 1^3 - 2(1)^2 - 5(1) + 6
= 1 - 2 - 5 + 6
= 0
so one factor is (x - 1) (by the Factor Theorem).
Divide f(x) by x - 1 we get:
x- 1) x^3 - 2x^2 - 5x + 6 ( x^2 - x - 6 <------ answer
x^3 - x^2
-x^2 - 5x
-x^2 + x
-6x + 6
-6x + 6
= x^2 - x - 6
= (x - 3)(x + 2).
