What is slope in plain ?
A line or a part of a line that connects two locations is said to have a slope, which is a measure of how steep it is.
The ratio of how much y grows as x grows by a certain amount is known as a line's slope. The slope of a line indicates how steep it is, or how much y rises as x rises.
The slope-intercept form of an equation is used whenever the equation of a line is expressed in the form y = mx + b.

113 disproves the conjecture that all number ending in 3 are divisible by 3
What is divisible rule ?Mathematicians use a set of precise rules called the "divisibility rules" to determine whether a given integer is divisible by a certain number or not. Examples of well-known divisibility tests range from 2 to 20. It enables us to calculate multiples and factors of numbers without having to use lengthy division. Applying the rules of divisibility, a person can determine if a number is divisible by another number or not.
Divisibility rule for 3 states that a number is completely divisible by 3 if the sum of its digits is divisible by 3.
243 is divisible by 3 as its sum is 2 + 4 + 3 = 9 and 9 easily get divided by 3
113 is not divisible by 3 as its sum is 5 and 5 can not divided by 3
therefore ,
113 disproves the conjecture that all number ending in 3 are divisible by 3

What number am I?

I am the only number
that gives a bigger
answer when you add
me to myself than when
you multiply me by
myself.
I am
Answers
Answer:
1
Step-by-step explanation:
We see that 1 + 1 = 2, while 1 * 1 = 1
So 1 gives a bigger answer when you add 1 to itself then when 1 is multiplied by itself
In the answer it is given that this is the only number for which this is correct, so there is not really a need to check for other options
but if you would want, you could just compute 2 till 9 and see that for example 2 + 2 = 4 and 2 *2 = 4, which are the same, so it is not a bigger number when added then when multiplied.

Answer: C) 6cm
Step-by-step explanation:
6³= 6x6x6
6x6x6= 216
Answer:
Choice C: 6 cm
Step-by-step explanation:
The sides of a cube are all of equal length
If each side is a cm, then the volume = a x a x a = a³ cubic cm
So a = ∛V where V is the volume
Since we are given V = 216 cm³,
each side = ∛21 = 6 cm

Quinn knit a total of 4 centimeters of scarf over 2 nights. how many nights will quinn have to spend knitting in order to knit a total of 70 centimeters of scarf?
Answers
The nights required by Quinn in order to knit a total of 70 centimeters of the scarf is equal to 35.
The number of nights required by Quinn in order to knit a total of 70cm of the scarf can be calculated using multiplication. Multiplication can be described as one of the four basic arithmetic operations in which we perform the repeated addition of the same number or value. This problem can be solved using cross-multiplication as follows;
2 nights = 4 cm of scarf
x nights = 70 cm of scarf
70 × 2 = 4(x)
140 = 4(x)
x = 140 / 4
x = 35
Therefore, Quinn will have to spend 35 nights knitting in order to knit a total of 70 centimeters of the scarf.

How many solutions exist for the following system if m1 ≠ m2?
y = m1x + b
y = m2x + b
answers:
an infinite number, none, one, the number of solutions cannot be determined.
Answers
Because the lines have different slopes, we conclude that there is only one intercept, and thus, the system of linear equations has only one solution.
How many solutions does the system of equations has?Remember that a system of equations has as many solutions as intercepts are when we graph both equations in the same coordinate axis.
Now, in this case, we have a system of linear equations:
y = m1*x + b
y = m2*x + b
Remember that linear equations are parallel only if the two lines have the same slope, in this case, we know that m1 ≠ m2, so the slopes are different.
Then the lines are not parallel, which means that intersect only one time, so we conclude that the system of equations has one solution.

the sat and act college entrance exams are taken by thousands of students each year. the mathematics portions of each of these exams produce scores that are ap- proximately normally distributed. in recent years, sat mathematics exam scores have averaged 480 with standard deviation 100. the average and standard deviation for act mathematics scores are 18 and 6, respectively.
Answers
a) 75.80 percentage of students will be scoring below 550 in a typical year.
b) 22.2 marks should be set by the engineering school setas a comparable standard on ACT math test.
Here we have been mentioned that in the recent years, sat maths exam scores have averaged 480 with standard deviation 100. the average and standard deviation for act mathematics scores are 18 and 6, respectively.
a) The percentage of the students scoring below 550 marks in a typical year is calculated as follows:
Let x be the SAT score
So, x follows normal distribution
Given above,
mean (μ) = 480
standard deviation (σ) = 100
we will find P ( x < 550)
We will use the excel function NORM.DIST to find the required probability
P(x < 550) = NORM.DIST[tex](550, 480, 100, TRUE)[/tex]
= 0.7580
= 75.80%
Hence the percentage of the students who are scoring below 550 in a typical year = 75.80%
b) We calculate the score to be set by the engineering school as a comparable standard on the ACT math test as follows:
Let Z be the ACT score
Z follows the normal distribution
Given above, μ = 18 and σ = 6
Let Z' be the ACT score comparable to the standard set for SAT
Then we need to find Z' such that P(Z < Z') = 75.80% = 0.758
From standard normal tables we get Y' such that
Z' = NORM.INV[tex](0.758, 18, 6)[/tex]
= 22.2
The ACT score that needs to be set by the college = 22.2 marks

The solution is : The true inequality is √x > x³, Option C.
What is inequality?An inequality is a relation which makes a non-equal comparison between two numbers or mathematical expressions.
Here, we have,
Given 0.5≤ x ≤ 0.7
According to the range of x, we will check which option is true
Let x = 0.6
A. x/3 > √x
If x = 0.6
∴0.6/3 > √0.6 ⇒ 0.2 > 0.77 ⇒ Wrong inequality
B. x³ > 1/x
If x = 0.6
∴ 0.6³ > 1/0.6 ⇒ 0.216 > 1.667 ⇒ Wrong inequality
C. √x > x³
If x = 0.6
∴ √0.6 > 0.6³ ⇒ 0.77 > 0.216 ⇒ True inequality
D. (x/3) > (1/x)

Answer:

Step-by-step explanation:
1x + 3x + -1y + 1y + 2z + 1z
1x + 3x = 4x
-1y + 1y = 0
2z + 1z = 3z
so the answer is 4x + 3z
x + 3x - y + y + 2z + z

In this expression, y cancels out because -1 + 1 = 0, and would therefore have no value.

Guenther drove 260 miles in 5 hours. He has 494 more miles to drive on his trip. If he continues at this same average speed, what will his driving time in hours be for the remainder of his trip?
Answers
The driving time in hours for the remainder of Guenther's trip would be = 9.5 hours.
What is average speed?Average speed of a moving object is defined as the average change in distance divided by change in time.
The first distance covered by Guenther = 260 miles.
The time it took to cover the first distance= 5 hours.
The remaining distance = 494 miles
The time it will take to cover the remaining distance= X hours
But if , 260 miles = 5 hours
494 miles = X hours

Abhasra made a trip to the town hall and back. On the trip there she drove 60 mph and on the return trip she went 75 mph . How long did the trip there take if the return trip took four hours ?
HELP ASAP PLEEASE!!
Answers
Answer:
Trip to town hall took 5 hours
Step-by-step explanation:
Distance traveled = Speed x Time
We know the return trip took 4 hours at 75 mph
So distance traveled from town hall to start = 75 x 4 = 300 miles
The distance from start to town hall is assumed to be the same.
So distance to town hall from start = 300 miles also
Time taken to travel 300 miles at 60 mph = 300/60 = 5 hours
