Answer:
0.38
Step-by-step explanation:
Look at the tenths decimal place to compare
3 is less than 4
9 is greater than 4
6 is greater than 4
5 is greater than 4
The only one less than 4 is 3 which corresponds to the decimal 0.38

Answer:
x = 1.55
y = 1.86
Step-by-step explanation:
Determinant of the original matrices;
Do = -3(4) -9(6)
Do = -12 - 54
Do = -66
For Dx
Replace the answer in the first column and fine the determinant
Dy = 17(-3) - 8(9)
Dy = -51-72
Dy = -123
y = Dy/Do
y = -123/-66
y = 1.86
Get Dx
Dx = 4 (-8) - 17(6)
Dx = -32-102
Dx = -134
x = Dx/Do
x = -132/-66
x = 1.55
Judy began her proof of the converse of the Pythagorean theorem by drawing triangle ABC with side lengths in inches of 5, 12, and 13. She then showed that 5^2 + 12^2=13^2 as follows.
5^2+12^2=13^2
25+144=169
169=169
Next, she drew triangle DEF, with two of the sides forming a 90° angle. If she has done her proof correctly so far, which of these is a length of one of the sides forming the 90° angle? Select two that apply.
A.3 in
B.4 in
C.5 in
D.12 in
E.13 in
Answer:
5 and 12
Step-by-step explanation:
If Judy has done her proof correctly, then the length of one of the sides forming the 90° angle is, 5. So Option C is one of the correct option.
What is Pythagoras theorem?It is the most important theorem of mathematics, which tells us the relationship between sides of the right angle triangle, which are known as Base(A), Height(B), Hypotenuse(H).
Pythagoras theorem,
H² = A² + B²
Given that,
Judy began her proof of the converse of the Pythagorean theorem
The triangle ABC with side lengths in inches of 5, 12, and 13
She showed that 5² + 12² = 13²
Now, In triangle DEF
One of the side length = ?
Suppose, the unknown side length = x
Let, two sides which having length,
base = 3 in.
height = 4 in.
Now, by using Pythagoras theorem
It can be written as,
H² = A² + B²
x² = 3² + 4²
Hence, the third unknown side is of 5 in.

In respect to person A:
6x + 2y = 25.92
3x + y = 12.96
y = 12.96 - 3x
In respect to person B:
4x + 3y = 33.93
Putting the value of y from the first equation in the second, we get
4x + 3(12.96 - 3x) = 33.93
4x + 38.88 - 9x = 33.93
- 5x = - 4.95
x = 0.99 dollars
Putting the value of x in the first equation, we get
y = 12.96 - 3x

What is the solution to the system of equations? 2x + 3y = 26 3x + 5y = 40
Answer:
x = 10 , y = 2
Step-by-step explanation:
The solution of the system of equations will be x= 10 and y = 2.
What is an expression?The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that the system of equations is 2x + 3y = 26 and 3x + 5y = 40. the two equations by elimination method can be solved as;-
2x + 3y = 26
3x + 5y = 40
Cross-multiply with the variable of x,
6x + 9y = 78
-6x - 10y = -80
___________
-y = -2
y = 2
The value of x will be:-
2x + 3y = 26
2x + 3 ( 2 ) = 26
2x = 20
x = 10
Hence, the solution of the system of equations will be x= 10 and y = 2.

Additional comment
A triple of integers that satisfy the Pythagorean theorem (form a right triangle) is called a "Pythagorean triple." One you see often, and that has the special property that it is the only triple that is an arithmetic sequence is (3, 4, 5). A couple of other common ones are (5, 12, 13) and (7, 24, 25).
Any of these can be scaled by a common factor to make sides of a right triangle. Here, we have (5, 12, 13) scaled by a factor of 1/8 to make (5/8, 12/8, 13/8) = (5/8, 3/2, 13/8) — the numbers in the problem statement.
If you're aware of these common triples, you can check to see if they are being used in any right-triangle problem you may run across. Recognizing that one of these applies can save you the effort of working out the squares and/or root that would otherwise be involved.

The distance a boy travels while hiking is a function of how fast he hikes and how long he hikes at this rate. The boy usually maintains a speed of miles per hour while hiking. Let t represent the input variable. Let h represent the function, and h(t)t the output variable. Evaluate and write a sentence describing its meaning. Write the result as an ordered pair.
Answer:
The distance you travel while hiking is a function of how fast you hike and how long you hike at this rate. You usually maintain a speed of three miles per hour while hiking.
Answer:
h(t)=3t
,where h(t) represents the distance we travel while hiking in time t which is the dependent variable.
Step-by-step explanation:
The distance we travel while hiking is a function of how fast we hike and how long we hike at this rate.
The maintained speed while hiking= 3 miles per hour
If t represent the time of hiking which is independent variable, and h(t) represents the distance we travel while hiking which is dependent variable.
Then, h(t)=3th(t)=3t

The mosquitos have different traits because they have different proteins for body size feature in their cells. Differences in the structure of protein molecules affect how they interact with other protein molecules. A gene version provides instructions for making a specific protein, so mosquitos with different combinations of gene versions will have different proteins in their cells that result in small, medium, or large body sizes. Each parent randomly passes on one of its two copies of a gene for a feature, which is why each mosquito offspring can have a different combination of gene versions even though they have the same parents.
Answer:
The mosquitos have different traits because they have different proteins for body size feature in their cells. Differences in the structure of protein molecules affect how they interact with other protein molecules. Genes provide rules for making particular energy, so mosquitos with different mixtures of genes will have different proteins in their cells that end up in different body sizes. Each parent randomly gives on one out of two of a gene for a characteristic, which is why each mosquito babies can have different mixtures of genes, even though they have the same parents.

Answer:
C
Step-by-step explanation:
y = -7x - 3 is a linear function that follow y = mx+b. M is the slope or rate. Here m = -7 so the fish descends 7 meters per second. B is the y-intercept or starting position. Here the starting position is -3 so the fish starts 3 feet below sea level.
