Answer:
4x ( 1 + 9x)
Step-by-step explanation:
4x + 36x²
= 4x ( 1 + 9x)
Solve for x
O 10°
O 189
O 20°
O 22.5°
Answer:
[tex]\boxed{x=10}[/tex]
Step-by-step explanation:
We are given two angles, which together, have a sum of 90°. We call these complementary angles. The angle ∠EAF is the complement of angle ∠FAB and vice versa.
Therefore, because they sum up to be 90°, we can simply add the angles together and solve for x this way.
[tex]4x+5x=90\\\\9x = 90\\\\\frac{9x}{9} = \frac{90}{9}\\\\\boxed{x = 10}[/tex]
The variable x equals 10. We can go even further to check and verify that this is correct by substituting our original value for x into the equation.
[tex]4(10)+5(10)=90\\\\40 + 50 = 90\\\\90 = 90[/tex]
90 does in fact equal 90, so your final answer is x = 10°.
Hope this helps! :)

put -3, 1 3/4, -0.5 and 3 least to greatest to least.
Answer:
-3, -0.5, 1 3/4, 3
Step-by-step explanation: in a number line negative is always less than positive so the bigger the negative number the more is goes down on the number line so that's why -3 is smaller then -0.5 because -0.5 is closer to positive than -3
Make 0.26 and a fraction
Answer:13/50
Step-by-step explanation:
Answer: 26/100 or 13/50

The sum of three consecutive odd integers is -75. What is the smallest number
Answer:
-27
Step-by-step explanation:
First, let's call the smallest number: n
Then, the next two consecutive odd numbers would be:
n+2 and n+4 (this is because it's only odd numbers so we add 2)
We know the sum of these is −75 so we can write this equation and solve for n:
n + (n + 2) + (n + 4) = -75
n + n + 2 + n + 4 = -75
n + n + n + 2 + 4 = -75
n + n + n + 6 = -75
1n + 1n + 1n + 6 = -75
3n + 6 = -75 Subtract 6 from each side, which cancels the 6 on the left.
3n + 6 - 6 = -75 - 6
3n = -75 - 6
3n = -81 Divide each side by 3
3n/3 = -81/3
n = -81/3
n = -27
n + 2 = -27 + 2 = -25
n + 4 = -27 + 4 = -23
The 3 consecutive odd integers would be:
-27, -25, -23
Let's check our work:
-27 + -25 + -23 = -75 We are correct!
The smallest number is -27

Men have XYâ (or YX) chromosomes and women have XX chromosomes.â X-linked recessive genetic diseasesâ (such as juvenileâ retinoschisis) occur when there is a defective X chromosome that occurs without a paired X chromosome that is not defective. Represent a defective X chromosome with lowercaseâ x, so a child with the xY or Yx pair of chromosomes will have the disease and a child with XX or XY or YX or xX or Xx will not have the disease. Each parent contributes one of the chromosomes to the child.
Required:
a. If a father has the defective x chromosome and the mother hasgood XX chromosomes, what is the probability that a son willinherit the disease?
b. If a father has the defective x chromosome and the mother asgood XX chromosomes, what is the probability that a daughter willinherit the disease?
c. If a mother has one defective x chromosome and one good Xchromosome, and the father has good XY chromosomes, what is theprobability that a daughter will inherit the disease?
d. If a mother has one defective x chromosome and one good Xchromosome, and the father has good XY chromosomes, what is theprobability that a daughter will inherit the disease?
Answer:
A) 0
B) 0
C) 0
D) 0.5
Step-by-step explanation:
We are told that Men have XY (or YX) chromosomes and women have XX chromosomes
A) If a father has the defective x chromosome and the mother has good XX chromosomes, the four possible outcomes will be;
{xX, YX, YX, xX}
The outcome for the son is;
{YX, YX}
The son will have the disease only if it's xY. Thus, probability of son having the disease is; 0/2 = 0
B) If a father has the defective x chromosome and the mother has good XX chromosomes, the four possible outcomes will be;
{xX, YX, YX, xX}
The outcome for the daughter is;
{xX, xX}
The daughter will have the disease only if it's xx. Thus, probability of daughter having the disease is; 0/2 = 0
C) If a mother has one defective x chromosome and one good Xchromosome, and the father has good XY chromosomes, the possible outcomes are;
{xX, xY, XX, XY}
Outcome for daughter is {xX, XX}
The daughter will have the disease it's xx. Thus, probability of daughter having the disease is; 0/2 = 0
D) If a mother has one defective x chromosome and one good Xchromosome, and the father has good XY chromosomes, the possible outcomes are;
{xX, xY, XX, XY}
The male outcome is;
{XY, xY}
The son will have the disease only if it's xY. Thus, probability of son having the disease is; 1/2 = 0.5

Please help me solve this equation and show the work show me how you got the answer
Answer: k=3
Step-by-step explanation:
To solve for k, you want to isolate k.
[tex]\frac{2}{5} (5k+35)-8=12[/tex] [add both sides by 8]
[tex]\frac{2}{5} (5k+35)=20[/tex] [multiply both sides by 5/2]
[tex]5k+35=50[/tex] [subtract both sides by 35]
[tex]5k=15[/tex] [divide both sides by 5]
[tex]k=3[/tex]
Now, we know that k=3.

which fraction is equal to 0.5 7
The value of fraction 0.5 7 is equal to 1/2.
We are given that;
Number = 0.57
Now,
There are different ways to express a fraction as a decimal, but one common method is to divide the numerator by the denominator.
For example, 1/2 as a decimal is 1 ÷ 2 = 0.512.
Another method is to use a fraction to decimal conversion chart or calculator345. According to these sources, 0.5 as a fraction is equal to 5/10 or 1/2.
These fractions are equivalent because they have the same value when simplified or reduced.
To simplify a fraction, we can divide both the numerator and the denominator by their greatest common factor (GCF).
Therefore, by algebra the answer will be 1/2.

What is Decimal ?Decimals are one of the types of numbers, which has a whole number and the fractional part separated by a decimal point.
Here, given value
0.02 = 002/100
= 2/100
On multiply numerator and denominator by 10, we get
0.02 = 20/1000
or 20 = 1000 X 0.02

put the steps for the deriving for the area of a triangle in the correct order
Answer:
See Below.
Step-by-step explanation:
Steps:
1) Draw the altitude of the triangle from Vertex B to side CA and label it h.
2) Find [tex]\sin(C)[/tex] of the triangle.*
3) [tex]\displaystyle \sin(C)=\frac{h}{a}[/tex]
4) Solve for h.
5) [tex]h=a\sin(C)[/tex]
6) Substitute expression for h into traditional formula for area of a triangle,[tex]\displaystyle A=\frac{1}{2}bh[/tex].
7) [tex]\displaystyle A=\frac{1}{2}ba\sin(C)=\frac{1}{2}ab\sin(C)[/tex]

Line a through (2, 3) is parallel to line b with equation y = -1, which point below a lso lies on line a? A (2,9) B(-5, 3) C (0, 1) D (1, 4)
Answer:
B (-5, 3)
Step-by-step explanation:
The line a passes through point ( 2,3 ).
Line b has equation y= -1
Plot the graph for line b, y=-1 , which is a horizontal line as shown in the attached graph
Plot point (2, 3) and draw the graph of line a, y=3 to form a line a parallel to line b
You will notice that point B (-5, 3) is the one the lies on line a.
The answer option A,(2,9) is incorrect because it does not lie on any of the lines
The answer option C (0, 1) is incorrect because it lies along the y-axis
The answer option D (1, 4) is incorrect because it does not lie on any of the lines.
