If 4/10 of the population have blood type O+, that means 40% of the population have that blood type. To change a fraction to percent, the easiest way is to make the denominator 100. To do this, multiply the whole fraction by 1 (1/1, 2/2, etc). In this case, multiply by 10/10. 4/10 * 10/10 is equal to 40/100. Then, if you have a denominator of 100, the numerator is the percent. Therefore, 40/100 is 40%.
Answer:
72 Centimeters
Explanation:
Formula for area: 1 /2 b · h
b = Base (18 cm.)
h = height (8 cm.)
1 / 2 Base: 9
height: 8
9 · 8 = 72
Therefore the area of the triangle is 72 centimeters
Answer:
20
Step-by-step explanation:
just substitute 0 for time in your equation, you will get 20.
Answer:
The polynomial would be x^4 - 5x^3 + 4x^2
Step-by-step explanation:
In order to find this, we need to take each answer and set it equal to x. Then we solve until it equals 0.
x = 4
x - 4 = 0
x = 1
x - 1 = 0
x = 0
x = 0
Now we have 4 of them and we simply multiply them all together.
(x)(x)(x - 1)(x - 4)
(x)(x)(x^2 - 5x + 4)
(x)(x^3 - 5x^2 + 4x)
x^4 - 5x^3 + 4x^2
