The percentage change in the number of burglaries over the two-year period is 35% .
The change in burglaries over the two-year period to have a 40% increase is 6.7%.
Let's assume that the annual number of burglaries in 2011 is 1000. After the 50% increase in 2012, the number of burglaries would be: 1000(1.50) = 1500.
The number of burglaries after the 10% reduction in 2013 would be: 1500(.90) = 1350
The change in burglaries over the two-year period = (1350 / 100) - 1 = 35%
In order to determine how much burglaries would have to reduce in order to have a 40% change in burglaries, this formula would be used
(x - 1000) / 1000 = 0.40
x - 1000 = 400
x = 1400
The change in burglaries over the two-year period to have a 40% increase = (1400 / 1500) - 1 = 6.7%

A $600 fax machine is on sale for 20% off. Find the amount of the discount and the sale price.
The amount of discount is $0.
The sale price is $0
Answer:
The amount of discount is $120
The sale price is $480
Step-by-step explanation:
The amount of discount = Original price × the Percentage off
The amount of discount = $600 × 20 %
The amount of discount = $600 × .20
The amount of discount = $120
The sale price = Original price - Discount
The sale price = $600 - $120
The sale price = $480

Step-by-step explanation:
You have to add all the numbers in the cube.
These are the following ones.
19 = 4 + 8 + 7
11 = 2 + 8 + 1
11 = 5 + 5 + 1
4 + 3 + 2 = 9

A high school teacher teaches three classes per day. Her first class has double the number of students as her
second class, while her third class has 13 more students than her second class. In total, she teaches 57
students. The equation 2x + x + (x +13) = 57 represents this scenario, where x is the number of students
in her second class.
How many students are in her second class?
Number
students are in her second class.
Answer:
11
Step-by-step explanation:
2x + x + x + 13 = 57
4x + 13 = 57
4x = 57-13
4x = 44
44/4 = 11
x = 11
To study the effects of a medication on migraines, every 10th adult from an alphabetized list of patients who suffer from migraines were selected. Then, the sample was surveyed about the number of migraines they have each month. The names of the 50 adults selected were written on equal sized tiles, placed in a bag, and mixed well. The people with names on the first 25 tiles selected were given the migraine medication. The remaining 25 people were given a placebo. After six months, all patients were surveyed again about the number of migraines they had each month. The change in the mean number of migraines between the two groups was compared.

The hypotenuse of an isosceles right triangle is 4cm longer than either of its legs note that an isosceles right triangle is a right triangle who’s legs are the same length find the exact length of its legs and it’s hypotenuse
Legs ? Cm
Hypotenuse? Cm
Answer:
Step-by-step explanation:
let the side of triangle=x
hypotenuse=x+4
(x+4)^2=x^2+x^2
x^2+8x+16=2x^2
x^2-8x-16=0
x²-8x=16
x²-8x+16=16+16=32
(x-4)²=16×2=(4√2)²
x-4=±4√2
x=4±4√2
either x=4+4√2=4(1+√2)
or x=4-4√2=-4(√2-1)<0 (rejected)
leg x=4(1+√2)≈4(1+1.414)≈4×2.414≈8.828≈8.83 cm
hypotenuse≈8.83+4=12.83 cm
What is the solution to the system of equations? y=−2x−64x−y=−36 (−15, 24) (−7, 8) (−5, 4) I don't know.
Answer:
Since y = −2x − 6 and 4x − y = −36, the solution would be B.) (-7, 8).
A solution to the given system of equations is [tex](\frac{100}{3}, \frac{8}{3} )[/tex]
Given the following system of equations:
[tex]y=-2x-64[/tex] ...equation 1.
[tex]x-y=-36[/tex] ...equation 2.
To find a solution to the given system of equations, we would use the substitution method:
First of all, we would make x the subject of formula in equation 2.
[tex]x=-36+y[/tex] ...equation 3.
Substituting eqn. 3 into eqn. 1, we have:
[tex]y = -2(-36+y)-64\\\\y=72-2y-64\\\\y+2y=72-64\\\\3y=8\\\\y=\frac{8}{3}[/tex]

Identify the axis of symmetry of the parabola.
A. y = 1
B. x = 1
C. y = −1
D. x = −1
Answer:
D. x = −1
Step-by-step explanation:
In the graph, the vertex of the parabola hits point (-1,-2). Therefore, the axis of symmetry is x = -1. It is not y = -2, since the parabola opens vertically, not horizontally.
Find the values of the six trigonometric functions for angle θ.Give answers in simplest form.
Answer:
Below in bold.
Step-by-step explanation:
The length of the side opposite to theta:
= √(24^2-21^2)
= √(24-21)(24+21)
= √(135)
= 3√15.
sin theta = 3√15/ 24 = √15/8. csc theta = 1/√15/8 = 8/√15 = 8√15/15.
cos theta = 21/ 24 = 7/8. sec theta = 8/7.
tan theta = 3√15/21 = √15/7. cot theta = 7/√15 = 7√15/15.

Is X=7 an oblique Line?
Answer:
no
Step-by-step explanation:
Generally oblique is used to describe the relationship between 2 lines, but only 1 is given. Oblique means slanted to a degree other than a multiple of 90°, usually in reference to the other line.
x = 7 is a vertical line, and that is exactly 90°, -90°, or even 270° or -270° depending on how you look at it, so it is not oblique on its own.
Answer:
x = 7 is not an oblique line.
Step-by-step explanation:
x = 7 is the standard equation for a vertical line, x = a, with an undefined slope. Vertical lines do not have horizontal change. Hence, its line will not be oblique (or slanted).
The equations in slope-intercept form (y = mx + b), standard form (Ax + By = C), and point-slope form [y - y₁ = m(x - x₁)] will most likely represent an oblique line, as long as its slope (m) ≠ 0. A line with a zero slope is a horizontal line (which is also not an oblique line).
Therefore, x = 7 is not an oblique line, but rather a vertical line.

The rectangle below is dilated by a scale factor of 3/2. Find the area of the dilated rectangle.
Answer:
108 square units
Step-by-step explanation:
When the dimensions are multiplied by 3/2, they become ...
8·3/2 = 12
6·3/2 = 9
Then the area of the dilated figure is ...
A = LW
A = 12·9 = 108 . . . . square units
_____
Additional comment
If you're paying attention, you see that the original area is multiplied by the square of the scale factor.
A = LW
A = (8·3/2)(6·3/2) = (8·6)·(3/2)²
This is generally true for the area of scaled figures: the original area is multiplied by the square of the scale factor to get the area of the scaled figure.
