The height of the tree in Jasmines drawing is; 6.25 inches tall
How to interpret Scale Drawing?The scale factor used by Louis is; 3in : 10 ft
The scale factor used by Jasmine is; 5in : 20ft
We are told that the tree in front of the school in Luis's drawing is 7.5 inches tall. Thus;
True height of tree in Louis drawing is; (7.5 * 10)/3 = 25 ft
Thus, height of tree in Jasmines drawing = (25 * 5)/20 = 6.25 inches tall

A teacher asks students to place tiles on the classroom wall to show the alphabet. The tiles will each have one letter or be blank. Each letter will have only one tile. The list shows the teachers rules for the arrangement of tiles.
• How many columns of tiles will there be?
• How many blank tiles will be used?
• What multiplication fact helped you solve the problem?
1. They must form a rectangle.
2. The rectangle must have 4 rows.
3. The rectangle must have the least possible number of columns.
The least possible number of columns is 7
2 blank tiles is will be used
Yes using multiplication facts the question can be solved.
Given data
Alphabet arrangement on tiles
The rules for arrangement of the alphabets
1. They must form a rectangle.
2. The rectangle must have 4 rows.
3. The rectangle must have the least possible number of columns.
How to find the column of tiles the arrangement will havenumber of alphabets = 26
let the row represent the width of the rectangle, so that the rectangle has 4 rows.
The length will be
length * width = 26
length = 26 / width
length = 26 / 4
length = 6.5 ≅ 7
Hence the least possible number of columns is 7
How to find the number of blank tiles used
26 / 4 gives 6 remainder 2 hence it requires 2 more tiles to make it up a rectangle of 7 columns.
The remaining part is filled with blank tiles therefore 2 blank tiles is used
How to solve the problem with multiplication factUsing multiplication we solve the problem as thus:
let the number of column be x such that
4 * x = 26
x = 26 / 4
so we use blank tiles to make the equation divisible by 4 without remainder.
using mental math: 28 / 4 = 7
therefore 2 blank tiles were added and the minimum number if rows is 7
Yes using multiplication facts the question can be solved.

A. The function must be a straight line. The function must be a straight line.
B. The function must pass the vertical line test. The function must pass the vertical line test.
C. The inverse relation must be a straight line. The inverse relation must be a straight line.
D. The inverse relation must pass the vertical line test.
the correct option is D:
" The inverse relation must pass the vertical line test."
Which is one condition that must be present for an inverse relation to be a function?
Remember that a relation is only a function if each value in the domain is only mapped into a single value in the range.
All functions need to pass what is called the "vertical line test" this means that if you draw a vertical line on the graph of the function, the vertical line can intersect the graph at most one time. If the vertical line intercepts the graph two or more times, then it is not a function.
From this we conclude that the correct option is D:
" The inverse relation must pass the vertical line test."

The equation of the circle is given by (C) (x-3)² + (y + 4)² = 9
All points in a plane that are at a specific distance from a specific point, the center, form a circle. In other words, it is the curve that a moving point in a plane draws to keep its distance from a specific point constant. The radius of a circle is the separation between any point on the circle and its center.
The equation of the circle in the general form is given by the
(x-a)²+(y-b)²=r²
Where (a,b) is the co-ordinates of the center of the circle and the radius is r.
Now the center of the circle is given at (3,-4) and the radius is r.
We know that the general equation of a circle is [tex]{\displaystyle (x-a)^{2}+(y-b)^{2}=r^{2}}[/tex]
Substituting the values in the equation we get:
(x-3)²+(y-(-4))²=(3)²
or, (x-3)²+(y+4)²=9
Hence the equation of the circle is (x-3)² + (y + 4)² = 9.

Which expression is equivalent to (2x − 1)(4x + 3) − (9x + 1)(2x − 1)?
The given expression (2x − 1)(4x + 3) − (9x + 1)(2x − 1) is equivalent to -10x^2 + 9x - 2, that is, option b.
If terms of the form (a + b) and (a + c) are to be multiplied, then each number or variable in the 1st term is multiplied by every variable in the 2nd term. Thus, (a + b)(a + c) = a^2 + ac + ab + bc.
Here, we are given an expression (2x − 1)(4x + 3) − (9x + 1)(2x − 1)
let us simplify the given expression-
[2x(4x) + 3(2x) -4x - 3] - [9x(2x) -9x + 2x -1)]
8x^2 + 6x - 4x - 3 - (18x^2 -9x + 2x -1)

12. CONCERT A concert venue surveyed
680 concert attendees about the concession
stand. Of those that visited the concession
stand, 527 said the concession stand prices
are excessive, and the remaining 44 did not.
Write an equation to find the number of
attendees a who did not visit the concession
stand. (Lesson 1-1)
Solving a linear equation, we will see that 109 attendees did not visit the concession stand.
How to find the number of attendees who did not visit the concession stand?
First, we know that the total number of surveyed people is 680.
Of these 680, we know that:
527 said that the concession stand prices are excessive.44 said that the concession stand prices are not excessive.x did not visit the concession stand.Now, the 3 numbers above should add up to the total number of surveyed people.
527 + 44 + x = 680
Solving that linear equation for x:
x = 680 - 527 - 44 = 109
We conclude that the number of attendees who did not visit the concession stand is 109.
