9.5 x 104 square miles. About how many
square miles is the area of the Great Lakes?
The area of the Great Lakes is 988 square miles.
According to the question,
We have the following information:
The area of the Great Lakes is about 9.5 x 104 square miles.
Now, the area of the Great Lakes can simply be found by multiplying the given two numbers.
Now, in the multiplication involving numbers with decimal points, we know that the numbers are multiplied first as if there is no decimal point but in the result obtained we put the decimal point to exactly counting the digits where the decimal point was placed in the input. We move the decimal point to the left hand side according to the number of digits.
In this case, point is after 1 digit.

how to find point-slope form off a graph
Solution
For this case we need to remember that the point-slope formula is given by:
y= mx+b

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]Then if we look at the graph we have two points:
x1= -2, y1= 3
x2= 0, y2= -1
And replacing we got:

From the problem, we have :

For 5/6, multiply this by 1/1 since the denominator is already 6.
[tex]\frac{5}{6}=\frac{5\times1}{6\times1}=\frac{5}{6}[/tex]For 1/2, multiply this by 3/3 to make the denominator equal to 6.

The price relative of a new Explorer compared to the cost of Explorer in 1990 is 1.66.
What is the price relative?The price relative is the ratio of the price of the Explorer today to the price of the Explorer in 1990. In order to determine the price relative, divide the price of the Explorer today to the price of the Explorer in 1990.
Division is the operation that is used to determine the quotient of two or more numbers. The sign that is used to represent division is ÷.

The number of citizens choosing cats, fish and dogs are 3360, 1820 and 3500 respectively.
Given, from the data which is represented by the pie chart, the percentage of citizens of a certain community choosing their favorite pet is listed below:
Fish = 13%
Dogs = 25%
Birds = 21%
Cats = 24%
Hamsters = 9%
Snakes = 8%
Altogether there are 14,000 citizens in the community.
we are asked to determine how many citizens have chosen cats, fish or dogs.
we use the method of percentage over here:
total citizens = 14000
percentage of citizens choosing cats = 24%
hence 24% of 14000 = 24/100 × 14000
= 24×140
= 3360
now, percentage of citizens choosing fish = 13%
hence 13% of 14000 = 13/100 × 14000
= 13×140
= 1820
And, percentage of citizens choosing dogs = 25%
hence 25% of 14000 = 25/100 × 14000
= 25 × 140
= 3500
hence the number of citizens choosing cats, fish and dogs are 3360, 1820 and 3500 respectively.

4 Which expressions represent the area of the triangle in square feet? Select all that apply. A. 48.9 B 16 +8719 D 16119 318319 E 16)(9) 1889)
Answer
Options B, C and D are correct.
Area = ½ × 14 × 9 = (14)(9) ÷ 2
Area = ½ (6 + 8) (9)
= ½ (6)(9) + ½ (8)(9)
= 63 ft²
Explanation
We are asked to pick out the options that give the area of the triangle.
To do that, we need to first note that the area of a triangle is given as
Area = ½ × Base × Height
For the triangle in the question
Base = 6 + 8 = 14 ft
Height = 9 ft.
So, the area of the triangle is
Area = ½ × Base × Height
Area = ½ × 14 × 9
We can then break this down for the two triangles in the one big triangle as
Area = ½ × 14 × 9 = (14)(9) ÷ 2
Area = ½ (6 + 8) (9)
= ½ (6)(9) + ½ (8)(9)
= 63 ft²

What is a set?
A set comprises elements or members that can be mathematical objects of any sort, including numbers, symbols, points in space, lines, other geometric forms, variables, or even other sets. A set is the mathematical model for a collection of various things. A set with a single element is a singleton, while a set with no elements is an empty set. A set can either be infinite or have a finite number of items. If all of the items in two sets are identical, then the sets are equal. Modern mathematics is rife with sets. In fact, since the first part of the 20th century, Zermelo-Fraenkel set theory has been the de facto method for constructing solid foundations for all areas of mathematics.
C₉³+C₉⁴+C₉⁵+C₉⁶+C₉⁷+C₉⁸+C₉⁹
C₉³ = 84 subsets consisting of 3 elements
C₉⁴ = 126 subsets consisting of 4 elements
C₉⁵ = 126 subsets consisting of 5 elements
C₉⁶ = 84 subsets consisting of 6 elements
C₉⁷ = 36 subsets consisting of 7 elements

And figure B is a trapezium with bases' lengths 2 and 4. And both trapeziums have the same height 2.
Thus, the figures are not congruent, not even similar.
Since the listed transformations map to congruent images of A, none of them maps A onto B.

The equation using the variable m to represent the cost of a Big Mac is
m + 1.07 = 15.07.
The cost of a Big mac is $14.
What is an equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
We have,

This can be written as an equation:
m + 1.07 = 15.07
Subtract 1.07 on both sides.
m + 1.07 - 1.07 = 15.07 - 1.07
m = 14
The cost of a Big mac is $14.

Find the equation of the line:
a) with a gradient of ½ and a y-intercept of -2
b) with a gradient of 3 and passing through the point (-2:2)
c) passing through the points (1; -2) and (-2; 1)
d) parallel to the y-axis cutting the x-axis at -1
Step-by-step explanation:
gradient means slope.
the slope is anyways the factor a of x on the slope-intercept form
y = ax + b
and in the point-slope form
y - y1 = a(x - x1)
"a" is as mentioned the slope. b is the y-intercept (the y- value when x = 0).
(x1, y1) is a point on the line.
a)
y = (1/2)×x - 2
b)
y - 2 = 3(x - -2) = 3(x + 2) = 3x + 6
y = 3x + 8
c)
remember, the slope is defined as ratio (y coordinate change / x coordinate change) when going from one point on the line to another.
so, let's go from (1, -2) to (-2, 1)
x changes by -3 (from 1 to -2)
y charges by +3 (from -2 to 1)
the slope is +3/-3 = -1/1 = -1
so, we pick one point, e.g. (1, -2), and the line is
y - -2 = -(x - 1) = -x + 1
y + 2 = -x + 1
y = -x - 1
d)
x = -1
this is a vertical line (parallel to the y-axis) representing all points on the grid for which x = -1.
the slope is undefined, as it is y/0 (because x never changes at all). and there is no y-intercept, as x can never be 0, and the line is parallel to the y-axis, so, there cannot be any intersection point.

Step-by-step explanation:
Part (a)Slope-intercept form of a linear equation:
[tex]y=mx+b[/tex]
where:
m is the slope.b is the y-intercept.Given values:
Slope = ¹/₂y-intercept = -2Substitute the given values into the formula to create the equation of the line:

Part (b)Point-slope form of a linear equation:
[tex]y-y_1=m(x-x_1)[/tex]
where:
m is the slope.(x₁, y₁) is a point on the line.Given:
Slope = 3(x₁, y₁) = (-2, 2)Substitute the given values into the formula to create the equation of the line:
[tex]\implies y-2=3(x-(-2))[/tex]
[tex]\implies y-2=3(x+2)[/tex]
[tex]\implies y-2=3x+6[/tex]
[tex]\implies y=3x+8[/tex]
---------------------------------------------------------------------------
Part (c)Slope formula:
[tex]\textsf{slope}\:(m)=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
where (x₁, y₁) and (x₂, y₂) are points on the line.
Given points:
(x₁, y₁) = (1, -2)(x₂, y₂) = (-2, 1)Substitute the points into the slope formula to calculate the slope of the line:
[tex]\implies m=\dfrac{1-(-2)}{-2-1}=\dfrac{3}{-3}=-1[/tex]
Substitute the found slope and one of the points into the point-slope formula to create the equation of the line:
[tex]\implies y-y_1=m(x-x_1)[/tex]
[tex]\implies y-(-2)=-1(x-1)[/tex]
[tex]\implies y+2=-x+1[/tex]
[tex]\implies y=-x-1[/tex]
