How can parents that dont have a O blood type still have a O blood type baby???
Answer: While a child could have the same blood type as one of his/her parents, it doesn’t always happen that way.
Step-by-step explanation:
For example, parents with AB and O blood types can either have children with blood type A or blood type B. These two types are definitely different than parents’ blood types!
#11 PLEASE HELP!!! URGENT!! NEED ASAP!!!
Answer:
See bolded answers
Step-by-step explanation:
Since 1=100%, then 1.15=115%, meaning x increased by 15% is correct
Since 1=100%, then 0.15=15%, meaning 15% of x is correct
Since 1=100%, then 0.85=85%, meaning x decreased by 15% is correct

Can anyone solve this? If so tell me and make sure u know what ur doing please
Answer:
-2
Step-by-step explanation:
To find the slope of a line, you need to find the [tex]\frac{rise}{run}[/tex] between two points. I will be using the points (-3, 2) and (-1, -2).
[tex]\frac{rise}{run}[/tex] = [tex]\frac{-2-2}{-1-(-3)}[/tex]
= [tex]\frac{-2-2}{-1+3}[/tex]
= [tex]\frac{-4}{2}[/tex]
= -2
What is the population density of 13 lillies living in an area of 6 meters (length) and 4 meters (width)?
Answer:
0.54 lillies per square meter.
Step-by-step explanation:
First we calculate the area:
Area = length * width
Area = 6 m * 4 m = 24 m²
The we divide the population of lillies (13) by the area, to calculate the population density:
13 lillies / 24 m² = 0.54 lillies/m²
So the population density is 0.54 lillies per square meter.

What fraction of state legislatures must approve an amendment before it becomes law
Answer:
3/4.
Step-by-step explanation:
The process of amendments to the Constitution of the United States is established and specified in Article V of said regulation. This process can be initiated by Congress or by the state legislatures, and once the amendment is approved by them, the legislatures of at least 3 out of 4 states (75% of the total) must ratify the amendment so that it becomes operative and is inserted into the constitutional text.
PLEASE SHOW FULL SOLUTIONS!! Will Mark Brainliest for the best answer. The radius of a spherical balloon is 3.5 cm. What is the volume of air in the balloon? Show your answer in terms of pi or round your answer to one decimal place.
THANKS
9514 1404 393
Answer:
343π/6 cm³ ≈ 179.6 cm³
Step-by-step explanation:
The formula for the volume of a sphere is one of the volume formulas worth memorizing. It is ...
V = (4/3)πr³
For r = 3.5 cm, the volume is ...
V = (4/3)π(3.5 cm)³ = 343π/6 cm³ ≈ 179.6 cm³
The volume of air in the balloon is about 179.6 cm³.

whats 2% as a decmial (show your work) p.s.a will give brainlest
Answer:
.02
Step-by-step explanation:
can't really show work since you don't solve
Answer:
2% as a decimal would be 0.02
Step-by-step explanation:
Where I learned, we do DR. Pepper. We use the DR. 2% is in the ones place. The decimal point goes from the right of R to the left of D. 2% would then be 0.02.
Find the zeros for each function
1. f(x)= x^3 + 12x^2 + 21x + 10
2. f(x) = x^4 + x^3 - 11x^2 - 9x + 18
9514 1404 393
Answer:
zeros are -10, and -1 (multiplicity 2)zeros are {-3, -2, 1, 3}Step-by-step explanation:
For higher-degree polynomials I find it extremely useful to use a graphing calculator to find the zeros.
The usual approaches are ...
use the rational root theoremtry values of x=±1narrow the search using Descartes' rule of signsestimate maximum or minimum root values__
1. Rational roots will be factors of 10, so ±1, ±2, ±5, or ±10. The signs are all positive, so there are no positive real roots. The sum of odd-degree coefficients is the same as the sum of even-degree coefficients, so -1 is one of the roots. Removing that using synthetic division gives you ...
f(x) = (x +1)(x^2 +11 +10)
The quadratic (more or less obviously) factors as (x+1)(x+10), so the complete factorization is ...
f(x) = (x +1)^2(x +10)
and the zeros are {-10, -1, -1}.
__
2. Rational roots will be factors of 18, so will be ±1, ±2, ±3, ±6, ±9, ±18. The sum of coefficients is 0, so x=1 is a root. The rule of signs tells you that there are 2 positive real roots, so there is one more positive real root. Synthetic division tells you the factoring so far is ...
f(x) = (x -1)(x^3 +2x^2 -9x -18)
We note that the first two coefficients have the same ratio as the last two, so we can factor by grouping.
x^3 +2x^2 -9x -18 = x^2(x +2) -9(x +2) = (x^2 -9)(x +2)
Factoring the difference of squares gives you the complete factorization, hence all of the roots. (The zeros are the values of x that make the factors zero.)
f(x) = (x -1)(x +2)(x -3)(x +3)
The zeros are {-3, -2, 1, 3}.

solve for x.
x/2.5<10
Answer:
x < 25
Step-by-step explanation:
x/2.5 < 10
you need to get x alone so you multiply both sides by 2.5 to get the 2.5 crossed out on one side
x < 2.5 times 10
