To calculate perimeter (borderline) of the rectangle use: 2(l+b). ‘It’s the same as adding the length of all four sides, you can do that too’
To calculate the area of a rectangle the formula is length*width
Now let’s look at the question. For part a it asks us to wrap ribbon *around* the mirror
This means the length of the ribbon will be the same as the perimeter of the mirror
Perimeter=
2(6+10)
= 2(16)
= 32 inches
For part be we have to find the area so:
Length * width
6 * 10 inches
= 60 inches

Find the value of x and YZ if Y is between X and Z. You may need to draw a picture. XY = 2x + 1, YZ = 6x, and XZ = 81 X YZ =
Answers
Answer:
x= 10
YZ=60
Step-by-step explanation:
X____Y____Z
XZ= XY+YZ
81 = (2x+1) + 6x
81 = 8x +1
8x = 81 -1
8x =80
x = 80/8
x = 10
YZ = 6x = 6(10) = 60

For a ride on a rental scooter, Dante paid a $2 fee to start the scooter plus 12 cents per minute of the ride. The total bill for Dante's ride was 16,28. For how many minutes did Dante ride the scooter?
Answers
Answer:
119 minutes
Step-by-step explanation:
First let's get rid of the starting fee of $2
[tex]16.28 - 2 = 14.28[/tex]
Then divide 14.28 by 0.12 ($14.28 ÷ $0.12)
[tex]14.28[/tex] ÷ [tex]0.12 = 119[/tex]
Thus Dante rode the scooter for 119 minutes
The number of minutes that Dante rode the scooter will be 119 minutes.
What is a linear equation?A relationship between two or more parameters that, when shown on a graph, produces a linear model. The degree of the variable will be one.
The linear equation is given as,
y = mx + c
Where m is the slope of the line and c is the y-intercept of the line.
For a ride on a rental scooter, Dante paid a $2 fee to start the scooter plus 12 cents per minute of the ride.
Let x be the number of minutes and y be the total amount.
y = 0.12x + 2
The total bill for Dante's ride was $16.28. Then the number of minutes that Dante rode the scooter will be
16.28 = 0.12x + 2
14.28 = 0.12x
x = 119 minutes
The number of minutes that Dante rode the scooter will be 119 minutes.

D. X is gold.

Answer:
C. X is not blue.
Step-by-step explanation:
Hi there!
We're given that if X is blue, then Y is gold, but Y is not gold.
Therefore, there is no way that X is blue, because if it was, then Y would be gold. But it's not, so X is not blue.

Perimeter of Triangle Please. Thank you ASAP
Answers
Step-by-step explanation:
The perimeter of a parallelogram is twice the sum of the length of a longer and a shorter side.
The length can be evaluated by the distance formula between two points (x_1,y_1), (x_2, y_2)
[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
For the longer side,
[tex]d=\sqrt{(7-(-4))^2+(3-2)^2}=\sqrt{122}[/tex]
or the shorter side,
[tex]d=\sqrt{(7-6)^2+(3-(-2))^2}=\sqrt{26}[/tex]
Therefore, the perimeter is given by,
[tex]2(\sqrt{122}+\sqrt{26})\approx254.2[/tex]

2 cos^2 (45°-A ) = 1 +sin 2 A
Answers
I am guessing that you mean 2cos2(45° - A) = 1 + sin2A
According to a double angle identity, 2cos2θ - 1 = cos(2θ)
So, 2cos2(45° - A) - 1
= cos (90° - 2A) =cos90°cos2A + sin90°sin2A = (0)cos2A + (1)sin2A = sin2
Thus, 2cos2(45° -A ) = 1 + sin2A

The given formula for y as; y=x/r-s
How to choose what quantity to multiply the first equation?This method is actually called method of elimination to solve a system of linear equations.
We make one specific variable's coefficients of equal magnitude so that we can subtract or add the equations and eliminate that variable to make it easy to get the value of the other variable which will then help in getting the value of the first variable (if working in dual variable system).
The given formula as; ry-sy=x
WE have to Solve for y means we have to make y alone.
ry-sy=x
Taking y as a common;
ry-sy=x
(r - s)y = x
Divide by (r - s) on both sides, we get
y = x/(r-s)

Step-by-step explanation:
The steps in the original function of f of B are
1. multiply by 2
2. subtract 9
Then the steps of the inverse equation would be
1. add 9
2. divide by 2
And this is what we see here. G is actually the inverse of f. Therefore B is the correct answer. If you repeat the same process for the other answers you'll find that it doesn't actually make an inverse.
You can also graph these to see whether or not its an inverse.
