An isosceles triangle has two sides that are twice as long as the third side. If the perimeter is 60, what is the length of each side of the triangle?
Answers
First side of triangle: 2x
Second side of triangle: 2x
Third side of triangle: x
Since all three sides add up to equal 60, we can set up the following equation and solve for each side:
(x) + (2x) + (2x) = 60
5x = 60 --> x = 12
Side 1 length: 2x = 2(12) = 24
Side 2 length: 2x = 2(12) = 24
Side 3 length: x = 12

R'after the translation (x,y) + (x-17-1), followed by a dilation by a scale factor of 2 centered at the origin?
Answers
Answer:
To find the scale factor for a dilation, we find the center point of dilation and measure the distance from this center point to a point on the preimage and also the distance from the center point to a point on the image. The ratio of these distances gives us the scale factor, as Math Bits Notebook accurately states.

Answer: 132
Step-by-step explanation:
Area of rectangle = length x width
(10 x 14. Add on the length of the triangle base)
Area of triangle = 1/2 base x height
(1/2*4 x 2. Notice the missing lengths on either side of 6 would be 2. 2 is also the height of the triangle)
In the figure, you have a rectangle with two equal triangles cut out at the bottom.
Find the area of the rectangle and subtract the area of the two triangles.
Area of rectangle 10x14= 140
Area of one triangle (1/2)4 x 2 = 4
Area of rectangle - two times area of triangle
140 - 2(4) =
140 -8 = 132

Which graph represents the solution say to the system of equations
Answers
Answer:
Step-by-step explanation:
System of equations has been given as,
y = [tex]-\frac{1}{2}x+3[/tex] -------(1)
and y = [tex]\frac{1}{2}x-1[/tex] -------(2)
Slope-intercept form of the equation of a line is,
y = mx + b
Here, m = slope of the line
b = y-intercept
By comparing this equation with the given lines,
y-intercepts of the given equations are 3 and -1
For solution of the systems,
[tex]-\frac{1}{2}x+3=\frac{1}{2}x-1[/tex]
[tex]\frac{1}{2}x+\frac{1}{2}x=3+1[/tex]
x = 4
From equation (2),
y = [tex]\frac{1}{2}(4)-1[/tex]
y = 1
Point of intersection of these lines is (4, 1).
Therefore, 4th graph (Extreme last from the left) will be the answer.

Ashton has an offer to buy an item with a sticker price of $4900 by paying

the TVM Solver of a graphing calculator will give him the correct answer for
the interest rate being offered?
A. N=4; 1% = ; PV=-4900; PMT=0; FV=140; P/Y=1; C/Y=12; PMT:END
B. N=4; 1% = ; PV=-4900; PMT=0; FV=6720; P/Y=1; C/Y=12; PMT:END
O C. N=4; 1% = ; PV=0; PMT=-4900; FV=6720; P/Y=1; C/Y=12; PMT:END
O D. N=4; 1% = ; PV=0; PMT=-4900; FV=140; P/Y=1; C/Y=12; PMT:END
Answers
The correct answer is b
We can plug them into the TVM Solver as follows:
N=4; 1% = ; PV=0; PMT=-4900; FV=6720; P/Y=1; C/Y=12; PMT:END
Option C is the correct answer.
What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example: so
1 + 3x + 4y = 7 is an expression.com
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
To use the TVM (Time Value of Money) Solver of a graphing calculator to find the interest rate being offered, we need to input the correct values in the calculator.
PV = -$4900 (negative because it represents a payment)
PMT = $140
N = 48
FV = $0 (because we are assuming Ashton will pay off the item in full)
Using these values, we can plug them into the TVM Solver as follows:
N = 48; I/Y = 1%; PV = -$4900; PMT = $140; FV = $0; P/Y = 1; C/Y = 12; PMT: END
Thus,
We can solve for I/Y, which gives us an interest rate of approximately 13.41%.
