Quadrilateral ABCD is a rectangle. BE=2x+1 and AC=6x−12 . What is BE ?
Answer:
BE=15
Step-by-step explanation:
Since E is the center, BE=2x+1
And AC is 6x-12 with E being a midpoint.
Since AC is 2 segments and BE is only 1 then you multiply 2x+1 by 2 so that
you can find x. You multiply 2x+12 by 2 because E is the midpoint so that means ED is the same value as BE
6x-12=4x+2
BD=AC
6x-4x-12=2
2x=2+12
2x=14
x=7
BE= 2x+1
2(7)=14+1=15
Work out the size of the angle marked t
Answer:
35°Step-by-step explanation:
This is an isoceles triangle
And as we all know an isoceles triangle has two equal base angles.
And we also know that the sum of all interior angles of the triangle is 180°
So based on this we can form an algebraic equation of solve for angke t (Let's do it :))
[tex]110 + 2t = 180 \\ 2t = 180 - 110 \\ 2t = 70 \\ t = \frac{70}{2} \\ t = 35[/tex]
So the base angle is 35°

Bob wants to buy a television that costs $600, including taxes. To pay for the television, he will use a payment plan that requires her to make a down payment of $240, and then pay $68.50 each month for 6 months. What is the percent increase from the original cost of the television to the cost of the television using the payment plan?
Answer:
108.5% increase
Explanation:
Find how much payments will cost for 6 months
68.50 × 6 = 411
Add payments to down payment
411 + 240 = 651
Compare:
600 vs 651
Solve for percent increase:
651 ÷ 600 = 1.085
Convert decimal into percentage:
1.085 × 100% = 108.5%

.Meiling needs 5 dollars 35 cents to buy a ticket to a show. In her wallet, she finds 2 dollar bills, 11 dimes, and 5 pennies. How much more money does Meiling need to buy the ticket?
Answer:
$2.20
Step-by-step explanation:
First you find how much money Meiling already has
2 dollars is $2.00
11 dimes is $1.10
5 pennies is $0.05
Add them all together
2 + 1.10 + 5 = 3.15
Then subtract how much Meiling need to how much Meiling has
5.35 - 3.15 = 2.20
Meiling still needs $2.20 for the ticket

The circumference of a circle is 20m. What is the area, in square meters?
Answer:
c = 62.83185
a = 314.15927 m²
Step-by-step explanation:
Hey There!
So first thing that we want to do is find the formula for the circumference
[tex]C=2\pi r[/tex]
where r = radius
we are given the diameter which we can easily convert to radius by dividing by 2
20/2=10
so the radius is 10
now we plug in
[tex]C=2\pi 10\\C=62.83185[/tex]
So the circumference is equal to 62.83185 m ²
Now to find the area we use the formula
[tex]A = \pi r^2[/tex][tex]10^2=100\\100\pi =314.15927[/tex]
so we can conclude that the area of the circle is 314.15927
can someone help?.............
Answer:
Step-by-step explanation:
The sum of the three interior angles of a triangle is always 180.
Knowing this, we can set up an equation for the given angles:
[tex]8x + 10x + 12x = 180[/tex]
[tex]30x = 180[/tex]
[tex]x = 6[/tex]
Knowing this, we can now plug it into the angles:
[tex]8x[/tex]
[tex]8 * 6[/tex]
[tex]48[/tex]
[tex]10x[/tex]
[tex]10 * 6[/tex]
[tex]60[/tex]
[tex]12x[/tex]
[tex]12 * 6[/tex]

Answer:
D. y = -1/2x + 18.5
Step-by-step explanation:
First you want to find the slope of the line that these coordinates make. To do this, use the slope formula: (y₂ - y₁) / (x₂ - x₁). I will use the first and last points.
(1, 18) & (6, 15.5)
Plug in these values:
(15.5 - 18) / (6 - 1)
Simplify the parentheses.
= (-2.5) / (5)
Simplify the fraction.
-2.5/5
= -1/2
This is your slope.
Now plug this into the standard slope-intercept equation: y = mx + b
y = -1/2x + b
b is the y-intercept, or the value of y when x = 0.
To find b, we want to plug in a value that we know is on this line: in this case, it is (1, 18). Plug in the x and y values into the x and y of the standard equation.
18 = -1/2(1) + b
To find b, multiply the slope and the input of x (1)
18 = -1/2 + b
Now, add 1/2 to both sides to isolate b.
18.5 = b
Plug this into your standard equation.
y = -1/2x + 18.5
This is your equation.
Hope this helps!

Step-by-step explanation:
the perimeter of a semicircle is 108 cm what is the perimeter of the square drawn on the diameter of the semicircle
Answer:
Step-by-step explanation:
the perimeter of the semi-circle would be the diameter plus the circumference of half of the circle.
They want to know the perimeter of a square using the diameter of the sem-circle as ONE side, so the perimeter of the square would be 4 times the ONE side.
We should recall:
diameter = 2 times the radius circumference of a cirlce = 2π r
How do we find the diameter of the of the semi circle?
The perimeter of the semi circle is given as 108 cm
Perimeter of the semicirle = 2r + π r diameter plus semi circumference
108 = r ( 2 + π) factor out the r and solve for r
108 / (2 + π) = r divide both sides by ( 2 + r)
Now we know r, the perimeter of the squqre is 4 times 2r or 8r
perimeter of square = 8 [ 108 / (2 + π) ] π I used 3.14
= 864 / 5.14
= 168.1 cm I got rounded to nearest tenth

Use the converse of the side-splitter theorem to determine if T R is parallel to R S. Which statement is true? Line segment TU is parallel to line segment RS because StartFraction 32 Over 36 EndFraction = StartFraction 40 Over 45 EndFraction. Line segment TU is not parallel to line segment RS because StartFraction 32 Over 36 EndFraction not-equals StartFraction 40 Over 45 EndFraction. Line segment TU is parallel to line segment RS because StartFraction 32 Over 45 EndFraction = StartFraction 40 Over 36 EndFraction. Line segment TU is not parallel to line segment RS because StartFraction 32 Over 45 EndFraction not-equals StartFraction 40 Over 36 EndFraction.
Line segment TU is parallel to line segment RS because 32/36 = 40/45.
What is side splitter theorem?According to the "Side Splitter" Theorem, a line that crosses two sides of a triangle and runs parallel to its third side proportionally divides those two sides.
A line will divide two sides of a triangle proportionally if it runs parallel to one of the sides and intersects the other two.
Given
It is evident from the presented figure that QT=32, TR=36, QU=40, and US=45.
The opposite of the side splitter theorem asserts that a line is parallel to a third side if it divides two sides proportionally.
TU separates the two sides by a factor of in
QT/TR = 32/36 = 8/9
QU/US = 40/45 = 8/9
QT/TR = QU/US
It implies that the line TU divides the two sides equally.
Line segment TU is parallel to line segment RS using the reverse of the side splitter theorem because
32/36 = 40/45
Hence option 1 is correct.

A 300 long wire is used to fence a rectangular plot whose length is twice its width find the length and breath
Answer:
Length = 100
Width = 50
Step-by-step explanation:
Given :
Length = 2 * width
If :
length = l
Width, w
l = 2w
Perimeter, P of rectangle :
P = 2(l + w)
P = 2(2w + w)
300 = 2(3w)
300 = 6w
w = 300/6
w = 50
l = 2w
l = 2(50)
l = 100
A spinner has 9 equal sections numbers 1-9. Determine the probability of spinning an odd number twice.
Answer:
25 /81
Step-by-step explanation:
Sample space = (1, 2, 3, 4, 5, 6, 7, 8, 9)
Probability = required outcome / Total possible outcomes
Odd numbers in sample space = (1, 3, 5, 7, 9) = 5
Required outcome = odd numbers = 5
Total possible outcomes = sample space = 9
P(odd outcome) = 5 /9
P(odd number twice) = 5/9 * 5/9 = 25 /81
