Answer:
[tex]m=15[/tex]
Step-by-step explanation:
Slope Formula: [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
Simply plug in the 2 coordinates into the slope formula to find slope m:
[tex]m=\frac{6-3}{0.4-0.2}[/tex]
[tex]m=\frac{3}{0.2}[/tex]

A line parallel to y = x - 7
Answer:
y = x - 10, y = x, y = x + 1, y = x - 37,654,356, which are just a few examples
Step-by-step explanation:
There are infinite solutions to this, but one of them is y = x - 10. Just change the y-intercept in this equation, then you can see that the lines never touch, and are parallel, which is what we want.
Write the mixed number 8 4/5 as an improper fraction.
The mixed number can be written as an improper fraction of 44/5 after simplifying the answer is 44/5.
What is a fraction?Fraction number consists of two parts, one is the top of the fraction number which is called the numerator and the second is the bottom of the fraction number which is called the denominator.
It is given that:
The mixed number is 8 4/5
To write the mixed number as an improper fraction:
= 8 + 4/5
Take LCM as 5
LCM can be defined as the common number of two integers, which is the lowest number that is a multiple of two or more numbers. The full name of LCM is the least common multiple.
= (8x5 + 4)/5
= (40 + 4)/5
= 44/5
Thus, the mixed number can be written as an improper fraction of 44/5 after simplifying the answer is 44/5.

The numbers of ancestors in different generations of a male honey be follow a fibonacci sequence In 5 generations email honey bee has 8 relatives and 6 generations it has 13 oz and in 7 generations it has 21 relatives how many relatives does it have an 8 and 9 generations?
Answer:
8th generation: 34 relatives
9th generation: 55 relatives
Step-by-step explanation:
Fibonacci sequence is a sequence that is in such a manner that each number will be the sum of the two preceding ones.
Thus, to get how many relatives in the 8th generation, we will need to add the number of relatives in both the 6th and 7th generation.
We are given number of relatives in the 6th and 7th generation as 13 and 21 relatives respectively.
Thus;
No. of relatives in 8th generation = 13 + 21 = 34 relatives
Similarly;
No. of relatives in 9th generation is = no. in 7th generation + no. in 8th generation = 21 + 34 = 55 relatives

What is a ratio defined?The quantity, amount, or size link between two or more things: proportionRatios are used to compare two numbers by dividing them. If you want to compare one data point (A) to another (B), your formula would be A/B. This signifies that you are dividing data A by data B. If A is five and B is ten, your ratio will be 5/10.A ratio indicates the number of times one number contains another. For example, if a dish of fruit contains eight oranges and six lemons, the orange-to-lemon ratio is eight to six (that is, 8:6, which is equivalent to the ratio 4:3).a line segment on a coordinate plane has a slope of 1 and the end points at (1,a) and (9,b).

The volumes of two similar solids are 729 m^3 and 125m^3. The surface area of a larger solid is 324 m^3. What is the surface area of the smaller solid
Answer:
100 m^2
Step-by-step explanation:
The scale factor of the volume of solids is the cube of the scale factor of linear dimensions.
The scale factor of the area of solids is the square of the scale factor of the linear dimensions.
Volume scale factor:
125/729 = (5/9)^3
Linear scale factor:
5/9
Area scale factor:
(5/9)^2 = 25/81
Proportion to find the area of the smaller one:
Let the area of the smaller one equal x.
25/81 = x/324
81x = 25 * 324
Divide both sides by 81
x = 25 * 4
x = 100
Answer: 100 m^2

What Is The Slope Of The Line Passing Through (-3, 5) and (5, -3)?
A. Slope = -1
B. Slope = 0
C. Slope = 1
D. No Slope
Answer:
Answer choice A. Slope -1
Step-by-step explanation:
If we plot the two points on a graph we can see that the points go from left to right, starting from a higher point to a lower point. This means the slope is negative. B and D are the same choice, but just in different words, and 0 cannot be positive or negative. and C is positive, not negative. So it is A. I hope this helps, and I hope it's not wrong, but I don't think it is.

A) 180°
B) 225°
C) 270°
D) 360°

We need to find a + b + c + d.
What is the sum of the angles in a right triangle?The sum of the angles in a right triangle must be 180 degrees.
We have,
In right-triangle PQR
PQ is perpendicular to QR.
So,
∠PQR = 90 degrees.
∠QPR = ∠QRP = 45 degrees.
We see that,
QS is perpendicular to PR
So,
∠QSP = b = 90 degrees
∠QSR = c = 90 degrees
Now,
From right-triangle QSP and right-triangle QSR.
We have,
QSP = b = 90 degrees
QPS = a = 45 degrees
QSR = c = 90 degrees
QRS = d = 45 degrees
Find a + b + c + d.
= 45 + 90 + 90 + 45
= 270 degrees
Thus the correct answer is 270°
a + b + c + d = 270°

Which line is perpendicular to the line shown on the graph Map testing
Answer:
Step-by-step explanation:
Since the graph with the line isn't provided, I can only tell/show you how to find the perpendicular line.
When two lines a perpendicular, they can have different y-intercepts. But the slope of line will change to it's reciprocal.
So if you have a line that is y = 2x + 7 the perpendicular line would be,
y = -1/2 x + 7
