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 ratio of boys to girls in Mr. Johnson’s class is 3:5. If there are 32 students in his class, how many of these students are girls? Write equation and solve.
Answer:
12:20
Step-by-step explanation:
3 : 5 = 3x : 5x = 32
3x + 5x = 8x = 32
x = 32/8 = 4
3x = 3x4 = 12
5x = 5x4 = 20

Answer:

Step-by-step explanation:
Calculate the slope m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
(8)
with (x₁, y₁ ) = (- 3, 2) and (x₂, y₂ ) = (8, 2)
m = [tex]\frac{2-2}{8+3}[/tex] = [tex]\frac{0}{11}[/tex] = 0
A slope of zero indicates the line is horizontal and parallel to the x- axis with equation
y = c
where c is the value of the y- coordinates the line passes through
The line passes through (- 3, 2) and (8, 2) with y- coordinates 2, thus
y = 2 ← equation of line
(9)
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
with (x₁, y₁ ) = (- 6, 1) and (x₂, y₂ ) = (- 3, 2)
m = [tex]\frac{2-1}{-3+6}[/tex] = [tex]\frac{1}{3}[/tex] , then
y = [tex]\frac{1}{3}[/tex] x + c ← is the partial equation
To find c substitute either of the 2 points into the partial equation
Using (- 3, 2) , then
2 = - 1 + c ⇒ c = 2 + 1 = 3
y = [tex]\frac{1}{3}[/tex] x + 3 ← equation of line

Step-by-step explanation:
The number line given run from -20 to +20 and so we record Niki's losses and wins using the negative numbers and positive numbers respectively. If Niki wins(scores 20 points) we add, that is a positive number on the number line. If Niki loses(loses 10 and 25 points) we subtract from her positive number using the negative values(points missed) on the number line. If we do this, Niki's value on the number line ends up at -15
To get Niki's final score, we calculate hence
+20-10-25 = -15 points

The price of silver has increased by 25% per year from 2000. In the year 2000,Harry bought a silver bowl for $170. Write a function F(x) that can be used to represent the price of the bowl in x years after 2000
Answer:
Results are below.
Step-by-step explanation:
Giving the following information:
The price of silver has increased by 25% per year from 2000. In the year 2000, Harry bought a silver bowl for $170.
To calculate the price of the silver bowl after x years, we need to use the following formula:
F(x)= PV*(1+g)^x
F(x)= future value
PV= present value
g= growth rate
x= number of years
For example, we determine the value of the coin after 10 years:
F(x)= 170*(1.25^10)
F(x)= $1,583.25
Answer:
F(x)= 170*(1.25^10)
F(x)= $1,583.25

it takes joan 5h to paint the porch, while jan can do it in 4h. how long will it tae them working together
It will take them 2 hours and 22 minutes to working together.
Here,
Joan paint the porch in 5 hours.
Jan can take 4 hours to paint the porch.
We have to find the time to take them working together.
What is Fraction?
A fraction simply tells us how many parts of a whole we have.
Now,
Let x is number of hours to take them working together.
Then, 1/x is how much of the porch they can paint together in 1 hour.
Joan paint the porch in 5 hours.
Then, Joan can take 1 hour to paint the 1/5 part of porch.
Jan can take 4 hours to paint the porch.
Then, Jan can take 1 hour to paint the 1/4 part of porch.
To find how much of the porch they can paint together in 1 hour, we can add together;
[tex]\frac{1}{5}+ \frac{1}{4} = \frac{1}{x} \\\\\frac{4+5}{20} = \frac{1}{x} \\\\\frac{9}{20} = \frac{1}{x}\\\\x = 20.22[/tex]
Hence, It will take them 2 hours and 22 minutes to working together.

A group of seven golfers paid $345 to play a round of golf. Of the golfers, one is a member of the
club and six are nonmembers. Another group of golfers consists of one member and three
nonmembers. They paid a total of $180. What is the cost for a member to play a round of golf,
and what is the cost for a nonmember?
Part 1 out of 2
The cost per member is S
Answer:
member = 15
nonmember = 55
Step-by-step explanation:
m = member, n= nonmember
1m+6n=345
2m + 2n =140 (divide all by 2 )
m + n = 70
m= 70 - n
70-n + 6n =345
70 + 5n = 345
5n = 345-70
5n = 275
n = 275÷5
n = 55
m = 70 - 55 = 15
m=15

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

The value of AG is 37cm
How to determine the valueFrom the diagram shown, we have that;
AG = 3x + 3GB = 11x + 6AB = 166cmBut;
AG + GB = AB
Let's substitute the values
3x + 3 + 11x + 6 = 166
collect like terms
3x + 11x + 9 = 166
14x = 166 - 9
14x = 157
Make 'x' the subject
x = 157/ 14
x = 11. 2cm
But line AG = 3x + 3 = 3 ( 11. 2) + 3 = 33. 6 + 3 = 37cm
