Answer:
25units²Step-by-step explanation:
Given the coordinates of three vertices of a square as A(1, –1), B(6, –1), and C(6, 4). The area of the square is expressed as;
A = L² where;
L is the one of the side length of the square.
Note that all the sides of a square are equal;
To get one of the side length, we will find the distance between any two of the coordinates points. Using the coordinates A(1, –1), B(6, –1)
L = AB = √(x2-x1)²+(y2-y1)²
L = √(6-1)²+(-1-(-1))²
L = √5²+0²
L = √25
L = 5
Area of the square = 5²
Area of the square = 25units²
Hence the area of the square is 25units²

−7x + 25 = 48 Step 1: −7x + 25 − 25 = 48 − 25 Step 2: −7x = 23 Step 3: negative seven times x over seven = twenty-three over seven Step 4: x = twenty-three over seven Step 1: He should have added 25 to each side. Step 1: He should have divided both sides by −7. Step 3: He should have divided both sides by −7. Step 3: He should have multiplied both sides by −7.
Answer:
Step 3: He should have divided both sides by −7
Step-by-step explanation:
Incorrect calculation
−7x + 25 = 48
Step 1: −7x + 25 − 25 = 48 − 25 Step 2: −7x = 23
Step 3: negative seven times x over seven = twenty-three over seven
-7*x/7 = 23/7
-7x/7 = 23/7
Step 4: x = twenty-three over seven
Correct calculation
−7x + 25 = 48
Step 1: −7x + 25 − 25 = 48 − 25 Step 2: −7x = 23
Step 3: negative seven times x over seven = twenty-three over seven
-7*x/-7 = 23/-7
-7x/-7 = 23/-7
Step 4: x = twenty-three over negative seven
x = -23/7

In a newspaper, it was reported that the number of yearly robberies in Springfield in 2012 was 90, and then went down by 50% in 2013. How many robberies were there in Springfield in 2013?
Answer:
m
Step-by-step explanation:
m
Answer:
There were 140 robberies in Springfield in 2012.
Step-by-step explanation:
Let's marked (named) robberies in 2012 with x, which is worth 100%
196 robberies in 2013 worth 100% + 40% = 140%
Now we will make proportion
x : 196 = 100 : 140
When we multiply external and internal members we get
140 x = 196 · 100 => 140 x = 19600 => x = 19600/140 = 140
x = 140 robberies in 2012
In standard form 0.0325 is written as?
Answer:
In standard form 0.0325 is written as 0.0325
In scientific notation it is written as:
[tex]3.25^{ - 2} [/tex]
The standard form of 0.0325 is written as
[tex] = 3.25 \times {10}^{ - 2} [/tex]
Given:
0.0325
Writing in standard form means writing in scientific notation (power of be 10)
When moving decimal point to the right, it is raised to a negative power of the number of times the decimal is moved.When moving decimal point to the left, it is raised to a positive power of the number of times the decimal is moved.0.0325
The decimal point will be moved 2 times before it gets between the be significant value of 3 and 2

You are given a various set of values: xbar = 12 ybar = 16 r = .46 Sy = 18 Sx = 6 Find a and b, then write them as an equation for a line. b = a = yhat =
Answer:
Slope, b = 1.38 ; intercept, a = - 0.56 ;
Y = - 0.56 + 1.38x
Step-by-step explanation:
Given that :
xbar = 12
ybar = 16
r = .46
Sy = 18
Sx = 6
The equation of a line can be expressed as :
Y = a + bx
Where ;
a = intercept ; b = slope ; x = independent variable ; y = dependent variable
The slope b ; can be obtained using the relation :
b = r(Sy / Sx)
= 0.46(18/6)
= 0.46(3)
= 1.38
The intercept a, can be obtained using the relation :
Ybar - b(Xbar)
16 - 1.38(12)
16 - 16.56
a = - 0.56
Hence ;
Slope, b = 1.38 ; intercept, a = - 0.56
Th equation of the line will be :
Y = - 0.56 + 1.38x

PLZ HELP I WILL GIVE 20 POINTS WHOEVER ANSWERS FIRST:
Answer:
-2
Step-by-step explanation:
So to find slope you just subtract y^1 - y^2 and divide it by x^1 - x^2
The first point is (2, 1)
The second is (0, 5)
1 is our y^1 and 5 is our y^2
1 - 5 = -4
2 is our x^1 and 0 is our x^2
2 - 0 = 2
So our slope is -4/2, reduced its -2

A train covers 165 km in 1.5 hours. How far will the train travel in 2.2 hours if it maintains the same speed?
Answer:
242
Step-by-step explanation:
165 ÷ 15 = 110
110 × 2.2 = 242
The distance that trains travel in 2.2 hours with the same ratio or same speed will be 242 km.
What are the ratio and proportion?The ratio is the division of the two numbers.
For example, a/b, where a will be the numerator and b will be the denominator.
Proportion is the relation of a variable with another. It could be direct or inverse.
As per the given,
A train covers 165 km in 1.5 hours.
The ratio of distance covered to the number of hours is 165/1.5.
Let's say in 2.2-hour train travel x number of km.
The ratio of distance covered to the number of hours x/2.2
Both ratios must be the same,
x/2.2 = 165/1.5
x = 110 x 2.2 = 242 km
Hence "The distance that trains travel in 2.2 hours with the same ratio or same speed will be 242 km".

Paul drank 18.2 ounces of water per day during soccer practice for a total of 54.6 ounces of water. Ryan drank 20.4 ounces of water each day after football practice for a total of 81.6 ounces of water. How many more days of practice did Ryan have than Paul?
A.
They both had the same number of days.
B.
1 day
C.
2 days
D.
3 days
Answer:
B
Step-by-step explanation:
Paul: 54.6/18.2= 3 days
Ryan: 81.6/20.4= 4 days
Answer:
B. 1 day
Step-by-step explanation:
First, we need to find how many days each person practiced for:
Paul- 54.6 ÷ 18.2 = 3
Ryan- 81.6 ÷ 20.4 = 4
4 - 3 = 1, so B is the answer.

Solve for x in the diagram below
Answer:
29
Step-by-step explanation:
(x+12) + 100 + x = 180
2x + 112 = 180
Subtract 112 from both sides
2x = 58
Divide 2 from both sides
x = 29
Suppose 15% of x equals 20% of y. What percentage of x is y ?
Answer:
x = [tex]133\frac{1}{3}[/tex] of y
Step-by-step explanation:
Given:
15% of x equals 20% of y
So,
0.15x = 0.20y
so
x = 0.20 y / 0.15
x = 1.3333y
x = [tex]133\frac{1}{3}[/tex] of y

Here is the other question
Part A and B are done
A. Lesson
1. Describe the formula for slope in words and with an equation.
M=y^2-y^1/x^2-x^1
1. What is the slope of all horizontal lines? What is the slope of all vertical lines?
The slope of all horizontal lines is 0. The slope of all vertical lines is undefined.
B. Lesson Content
3. Copy and paste the 3-step procedure for finding the slope using the formula.
4. Use Example 3 as your model for the following: In the 2000 census, the population was 8000; in the 2010 census, the population was 7500. Find the rate of growth for the town. Show the 3-step procedure, as well as the final answer in words.
A(200(x1), 8000(y1)) and B(2010(x2), 7500(y2))
M=(y2-y1)(x1-x2)=7500-8000/2010-2000
M=-50=50 people per year decrease
C. Write the slope-intercept (y = mx + b) form of the equation from the information given. Show your steps as done in the lesson content to earn credit.
Answer:
Step-by-step explanation:
Slope is m
in this case slope is -50
b is the y-int,
in this case the y-int is 8000
so your equation: y = -50x + 8000

what is the square root of 199 lie between
Hi!
I'm assuming the question means what integers, so let's figure it out.
Starting from 12, 12 squared is 144, or the square root of 144 is 12.
13 squared is 169, or the square root of 169 is 13.
14 squared is 196, or the square root of 196 is 14.
15 squared is 225, or the square root of 225 is 15.
Based on that list of numbers, we can determine that the square root of 199 lies between the square root of 196 and the square root of 225 -- aka 14 and 15.

line g has and undefined slope. If line k contains the point (-6,3) and is parallel to line g, what are the x-coordinates of the other points that lie on the line?
Answer:
-6 is the x-coordinate value
Step-by-step explanation:
Mathematically, slope can be calculated as;
m = (y2-y1)/(x2-x1)
For the value of the slope to be undefined, it means that we are actually dividing by zero
For us to be dividing by zero, it actually means that there is no change in the x-value
The unchanging x-value is what has caused us to have an undefined slope value
Since line k and line g are parallel, their slopes are equal and the slope of k is undefined too
So the x-coordinates of the other points that lie on the line that we used in calculating the slope is -6
