liliana decides to crop a square photo 2 inches on each side to fit it into a frame. the area of the original photo was 121 square inches. in the equation (x 2)2
The dimensions of the cropped photo will be 9 inches by 9 inches
Step-by-step explanation:
From the formula of area of square
Length x width = area
[tex]x^{2}[/tex] = area
But we are given the equation as
[tex](x+2)^{2}[/tex] = 121
The equation gives the measures of the cropped dimension as "x". This means we need to solve the equation
[tex](x+2)^{2}[/tex] = 121
[tex]x^{2}[/tex] + [tex]2^{2}[/tex] + 2(x) (2) = 121
[tex]x^{2}[/tex] + 4 + 4x = 121
[tex]x^{2}[/tex] + 4x -117 = 0
[tex]x^{2}[/tex] + 13x - 9x -171 = 0
x( x+13) -9 (x+13) = 0
(x+13)(x-19) =0
This means
x = 9, -13
Since, dimension can't be negative. So, the measure of dimension would be 9 inches by 9 inches

The teacher has the following cards in a bag::
what is the probability that the teacher randomly selects a card with an 8 on it?
Answer:
20% or .20
Step-by-step explanation:
There are a total of 10 cards in the sample.
Of these 10 cards there are 2 of them with the number 8 on them.
To find the probability, you divide the part (2) over the whole (10)
2/10 = .20
Then you can multiply by 100 to find the percent
(.20)(100) = 20%
Therefore, if the teacher were to select a card at random there is a 20% chance that it has the number 8 on it.
I hope this helps!

How long will it take for a debt to double at 42% p.a. compound interest?
According to the given statement ,
a debt to double at 42% p.a. compound interest will take approx 2 years.
What is compound interest ?Compound interest, also known as interest on principal and interest, is the practice of adding interest to the principal amount of a loan or deposit.
Compound interest is calculated on the initial principal of a deposit or loan, which also takes into account all of the accumulated interest from prior periods.
The yearly interest rate is raised to the number of compound periods minus one, and the starting principal amount is multiplied by both of these factors.
According to the given data,
Let principal = P
Time = t
Rate == 42%
Amount = A
Given Condition is A = 2P
=> P[1+ r/100]ⁿ = 2P
=> P [1 + 42/100 ]ⁿ = 2P
=> (1.42)ⁿ=2
n= log₁.₄₂ 2 =0.301/0.152
n=1.980≅2
Hence , the time it take for a debt to double at 42% p.a. compound interest is approx 2 years.

a rectangular window frame has demotions expressed by 3x and (2x -5). find a simplified expression for its perimeter and determine the actual perimeter if x equals 3meteres
Answer: Simplified Equation (10x-10)
Answer if 3=x is 20
Step-by-step explanation:
the original side lengths are 3x and (2x-5) so multiply both those by 2.
Now you have 6x and 4x-10.
Now combine those and you have 10x-10.
Then plug in 3 for x

8x10^3 is how many times as large as 4x10^2
Answer:
(3.2 × 10²) times as large
Step-by-step explanation:
First, set up an equation:
(8 × 10³) ÷ (4 × 10²)
Using the laws of exponents, we know that when two exponents with the same base are being divided by each other, the exponents subtract from each other:
(8 × 4) × (10³⁻²) = (32 × 10¹)
Move the decimal one space to the left, which increases the exponent by 1:
(3.2 × 10²)

Is Figure A’B’C’D a reflection of figure ABCD ? A: yes it is a reflection over the x-axis. B: yes it is a reflection over the y-axis. C: yes it is a reflection over line f. D: no it is not a reflection
A’B’C’D' will be a reflection of figure ABCD about line f
what is a reflection about a line?A reflection over a line l(notation l) is a transformation in which each point of the original figure (pre-image) has an image that is the same distance from the line of reflection as the original point but is on the opposite side of the line.
reflection of point D will be D' if the distance between point D and line f is the same as the distance between point D' and line f
let us consider point (10,0) on line f for our convenience. we will calculate each distance from this point (10,0)
distance is 2 units from both the points D and D'
reflection of point C will be C' if the distance between point C and line f is the same as the distance between point C' and line f
distance of point C from line f= distance of point C' from line f
[tex]\sqrt{(14-10)^2 + (-2-0)^2} = \sqrt{(10-8)^2+ (4-0)^2} =\sqrt{20}[/tex]
similarly, point A and B will also be equidistant from line f
therefore, A’B’C’D' will be a reflection of figure ABCD about line f.

an ordinary (fair) die is a cube with the numbers 1 through 6 on the sides (represented by painted spots). imagine that such a die is rolled twice in succession and that the face values of the two rolls are added together. this sum is recorded as the outcome of a single trial of a random experiment. compute the probability of each of the following events. event : the sum is greater than 5. event : the sum is divisible by 2 or 3 (or both).
Probability of sum greater than 5 event is reduces to 13/18 .
Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur, or how likely it is that a proposition is true. The probability of an event is a number between 0 and 1, where, roughly speaking, 0 indicates impossibility of the event and 1 indicates certainty.
probability of getting number whose sum is divisible by 2 and 3 both is 6/36 which reduces to 1/6 .
The sample space of rolling two dice has 36 possible outcomes. Remember that the "sample space" is a set which contains all possible outcomes. (1,1)(2,1)(3,1)(4,1)(5,1)(6,1)(1,2)(2,2)(3,2)(4,2)(5,2)(6,2)(1,3)(2,3)(3,3)(4,3)(5,3)(6,3)(1,4)(2,4)(3,4)(4,4)(5,4)(6,4)(1,5)(2,5)(3,5)(4,5)(5,5)(6,5)(1,6)(2,6)(3,6)(4,6)(5,6)(6,6)
The probability of the sum is greater than 5 event is 26/36 which reduces to 13/18 .And the probability of getting number whose sum is divisible by 2 and 3 both is 6/36.
