Answer:
Blood groups are inherited from both parents. ... Individuals with IAIA or IAi have type A blood, and individuals with IBIB or IBi have type B. IAIB people have both phenotypes, because A and B express a special dominance relationship: codominance, which means that type A and B parents can have an AB child.

What is the slope of a line that is perpendicular to the line whose equation is 8y−5x=11?
Ill give someone brainlist
9514 1404 393
Answer:
-8/5
Step-by-step explanation:
When you solve for y, the slope of the line is the x-coefficient. For the given line, that is ...
8y = 5x +11 . . . . . add 5x
y = 5/8x +11/8 . . . . divide by 8
The given line has a slope of 5/8. The perpendicular line will have a slope that is the opposite of the reciprocal of this:
-1/(5/8) = -8/5 . . . . slope of perpendicular line
Answer:
The slope of the perpendicular line will be -8/5, or -1.6
Step-by-step explanation:
First we need to rearrange the equation to show the slope, putting in the format y = sx + c:
[tex]8y - 5x = 11\\8y = 5x + 11\\y = \frac{5}{8}x + \frac{11}{8}[/tex]
So the given line has a slope of 5/8.
A line perpendicular to that will have a negative reciprocal of that slope, so it's slope will be -8/5.

A 13ft ladder is leaning against a wall when its base starts ti slide away from the wall. By the time its base is 12 feet from the wall, the base is moving at the rate of 5ft/sec. How fast is the top of the ladder sliding down the wall?
Given :
A 13ft ladder is leaning against a wall when its base starts ti slide away from the wall.
By the time its base is 12 feet from the wall, the base is moving at the rate of 5ft/sec.
To Find :
How fast is the top of the ladder sliding down the wall.
Solution :
By, Pythagoras theorem, distance of ladder from horizontal to wall is 5 feet.
Now, [tex]x^2 + y^2 = 13^2[/tex]
Differentiating both sides, we get :
[tex]2x\dfrac{dx}{dt}+2y\dfrac{dy}{dt}=0\\\\(2\times 12\times 5) + (2\times 5 \times \dfrac{dy}{dt})=0\\\\\dfrac{dy}{dt}= -12 \ feet/sec[/tex]

Answer:
(2x^2 + x-7)/3x+ 3
Step-by-step explanation:
Here, we want to write the following as a single fraction;
2x-1/3 - 2/x + 1
That will be;
(2x-1)(x + 1) -2(3)/3(x+ 1)
= 2x^2+ 2x-x-1-6/3(x + 1)
= (2x^2+x-7)/3(x+1)
= (2x^2 + x-7)/3x+ 3

Samiya bought a tree 3 inches long. Each year, the tree expected to grow 5 inches. How long (How many years) it takes the tree to reach the height of 8 feet (or 96 inches)? Let \large y be number of years it takes to reach 96 inches tall;
Answer:
19 years
Step-by-step explanation:
Initial height of tree when Samiya bought the tree = 3 inches
Growth in the height of tree every year = 5 inches
Number of years = [tex]y[/tex]
Growth in the height of tree in [tex]y[/tex] years = 5 inches multiplied by number of years
Growth in the height of tree in [tex]y[/tex] years = 5[tex]y[/tex] inches
To find:
Number of years taken by the tree to be 8 ft or 96 inches.
Solution:
The equation for height of tree after [tex]y[/tex] years can be written as:
3 + 5[tex]y[/tex] which is to be compared with 96 inches.
Therefore, the equation is:
[tex]3 + 5y = 96\\\Rightarrow 5y=93\\\Rightarrow y \approx 19[/tex]
Therefore, it will take 19 years for the tree to reach a height of 96 inches.

Which system of equations is represented by this graph?
y= _ x+3
y= _ x-3
The system of equations represented by the graph are
y = 2x + 3 and y = (-1/2)x - 3
What is an equation of a line?The equation of a line is given by:
y = mx + c
where m is the slope of the line and c is the y-intercept.
Example:
The slope of the line y = 2x + 3 is 2.
The slope of a line that passes through (1, 2) and (2, 3) is 1.
We have,
The equation of one line on the graph.
y = mx + c
Select two coordinates from the line.
(0, 3) and (-3, -3)
m = (-3 - 3) / -3 = -6/-3 = 2
(0, 3) = (x, y)
3 = 0 + c
c = 3
The equation of the line is y = 2x + 3
The equation of the other line on the graph.
y = mx + c
Select two coordinates from the line.
(0, -3) and (2, -4)
m = (-4 + 3) / 2 = -1/2 = -1/2
(0, -3) = (x, y)
-3 = 0 + c
c = -3
The equation of the line is y = (-1/2)x - 3
Thus,
y = 2x + 3 and y = (-1/2)x - 3 are the system of equations.

Sydney has a bag of stuffed animals containing, 1 elephant, 4 bears, 3 cats, and 2 dogs. If she randomly selects 1 stuffed animal from the bag, places it on her bed and then selects another animal. What is the probability that she chooses a bear both times?
Answer:
2/15
Step-by-step explanation:
Step one:
given data
sample space
1 elephant,
4 bears,
3 cats, and
2 dogs.
sample size= 1+4+3+2= 10
Required:
By selecting without replacement, the probability that she chooses a bear both times
Step two:
the first event= Pr(bear)= 4/10= 2/5
the second event, the sample size is now 9 and the number of bears is now 3
Pr(bear)= 3/9= 1/3
Hence, the probability that she chooses a bear both times
= 2/5*1/3
=2/15

Trent has 12 cups of ice cream for his daughter's birthday party
If each serving is
3/4
of a cup, how many children can eat ice cream?
А
1
B
9
С
12
D
16
Answer:
B. 9
Step-by-step explanation:
12 times 3/4 is 9
Answer:
it takes 4 of the 3/4 servings to make a whole number and it's 3 cups.
12/3= 4 and 4*4= 16
so 16 children can eat ice cream
or you could do 12/0.75= 16
you would do that because 3/4=0.75
you would divide and not multiply because you're seeing how many times 0.75 can go into 12

Calculate the average speed of an insect that walked 27 centimeters in 9 seconds. *
A 9 cm/s
B 27 cm/s
C 243cm/s
D 3 cm/s
Answer:
D) 3cm/s
Step-by-step explanation:
Speed (or velocity) is calculated with d/t (distance/time). From the multiple-choice options, we know the unit is cm/s, which makes it super convenient.
Now, using the equation and seeing that 27cm is the distance and 9s is the time, 27/9 =3.
Therefore, the answer is D, 3cm/s.

OA. 3
O B. 4
O C. 7
O D. 8
Answer:
C
Step-by-step explanation:
Answer:
B. 4
Step-by-step explanation:
5x - 2(2x-1) = 6 Distribute first the 2 to (2x-1)
5x - 4x + 2 = 6 Subtract 5x - 4x
x + 2 = 6 Transpose 2 to the right side by subtracting both side by 2
x = 6 -2
x = 4
