Answer:
As property of a rectangle:
1. AC = 13
AC = 2 x EC (E is midpoint of AC and BD)
13 = 2 x (3x - 11)
13 = 6x - 22
35 = 6x
x = 35/6 m
2. DB = AC = 13 m( two diagonals are equal)
3. BAE = ABE = 40 degree
4. BDA = 90 - ABE = 90 - 40 = 50 (triangle ABD is a right triangle at A)
5. BC = AD = 5m (two opposite sides are equal)
6. AB = sqrt(BD^2 - AD^2) = sqrt(13^2 - 5^2) = sqrt(144) = 12 m
Perimeter = 2 x (AD + AB) = 2 x (5 + 12) = 2 x 17 = 34 m
7. Area= AD x AB = 5 x 12 = 60 m2

Answer:
y = 1.48 or y = - 0.193 to 3 s f.
Step-by-step explanation:
By comparing the 2 equations term by term we see that x = 1/y
So 1/y = 0.676
giving y = 1 / 0.676
= 1.48 to 3 s f.
an
1/y = -5.18
y = - 0.193 to 3 s f.
Evaluate f (x) = 2 x torx =-5.
Answer:
-10.
Step-by-step explanation:
f(x) = 2x, x = -5.
f(-5) = 2(-5)
= 2 * (-1) * 5
= 10 * (-1)
= -10.

Ms.Kayla theatre group is having a play. On Thursday the ticket sale is 287, Friday ticket sale was 618, Saturday ticket sale was 973, and on Sunday the ticket sale was 532. Which two-day ticket sales can be combined to equal more than the tickets sold on Saturday. Please show your work I will mark you brainiest and show your work, please
Answer:
Friday & Sunday
Step-by-step explanation:
Thursday: 287
Friday: 618
Saturday: 973
Sunday: 532
973 < 287 + 618 = 973 < 905
We now know this isn't true.
973 < 287 + 532 = 973 < 819
This isn't true either.
973 < 532 + 618 = 973 < 1150
This is true. The two days with the time are Friday and Sunday.
I really hope this helps you! Tell me if it's right or not! :D

Answer:
The coordinates of D′ if polygon ABCD rotates 90° counterclockwise to create A′B′C′D′ is at (-2, 2)
The coordinates of C″ if polygon ABCD rotates 90° clockwise to create A″B″C″D″ is at (3, -1)
The coordinates of A′′′ if polygon ABCD rotates 180° clockwise to create A′′′B′′′C′′′D′′′ is at (4, -2)
The coordinates of B″ if polygon ABCD rotates 270° counterclockwise to create A″B″C″D″ is at (4, 2)
Step-by-step explanation:
A transformation is the movement of a point from its initial position to a new position. If a shape is transformed, all its points are also transformed. Types of transformation are reflection, rotation, dilation and translation.
Given Polygon ABCD is defined by the points A(-4, 2), B(-2, 4), C(1, 3), and D(2, 2).
If a point X(x, y) is rotated 90° counterclockwise, the new location X' is at (-y, x)
If a point X(x, y) is rotated 90° clockwise, the new location X' is at (y, -x)
If a point X(x, y) is rotated 180° clockwise, the new location X' is at (-x, -y)
If a point X(x, y) is rotated 270° counterclockwise, the new location X' is at (y, -x)
The coordinates of D′ if polygon ABCD rotates 90° counterclockwise to create A′B′C′D′ is at (-2, 2)
The coordinates of C″ if polygon ABCD rotates 90° clockwise to create A″B″C″D″ is at (3, -1)
The coordinates of A′′′ if polygon ABCD rotates 180° clockwise to create A′′′B′′′C′′′D′′′ is at (4, -2)
The coordinates of B″ if polygon ABCD rotates 270° counterclockwise to create A″B″C″D″ is at (4, 2)
Answer:
Transformation is the movement of a point from its initial location to a new location. Types of transformation are rotation, reflection, translation and dilation.
If a point A(x, y) is rotated 90° counterclockwise, the new point is at A'(-y, x).
If a point A(x, y) is rotated 90° clockwise, the new point is at A'(y, -x). If a point A(x, y) is rotated 180° counterclockwise, the new point is at A'(-x, -y).
If a point A(x, y) is rotated 270° counterclockwise, the new point is at A'(y, -x).
Polygon ABCD is defined by the points A(-4, 2), B(-2, 4), C(1, 3), and D(2, 2).
The coordinates of D′ if polygon ABCD rotates 90° counterclockwise to create A′B′C′D′ is D'(-2, 2)
The coordinates of C″ if polygon ABCD rotates 90° clockwise to create A″B″C″D″ is C"(3, -1).
The coordinates of A′′′ if polygon ABCD rotates 180° clockwise to create A′′′B′′′C′′′D′′′ is A''"(4, -2)
The coordinates of B″ if polygon ABCD rotates 270° counterclockwise to create A″B″C″D″ is B"(4, 2)
Are the ratios 11:9 and 2:1 equivalent?
yes or no
Answer:
no
Step-by-step explanation:
We can determine if they are equivalent if the cross products are equal
11 2
----- = ------
9 1
11*1 = 2*9
11 = 18
This is false so the ratios are not equivalent

£200
Step-by-step explanation:
4 friends - 4 tickets
They need to BUY 3 tickets.
3 tickets will cost £1200
Divide the £1200 between the 4 friends which is £300.
They will then get the other 1 ticket for free and have 4 altogether!
Katherine's class is selling raffle tickets for $3 to raise money for charity. Katherine's class raised $504. Which equation would you use to find the number of tickets sold?
Hey there! I'm happy to help!
Let's represent each ticket with the variable t. For each ticket sold, there will be 3 dollars added to the total. So, if you multiply the number of tickets by 3, you will have your total.
This gives us the following equation.
3t=504
We could use this equation to find the number of tickets sold by dividing both sides of it by 3, which isolates the t, showing us that t=168.
Have a wonderful day!
Answer:
$504 / $3 = t
Step-by-step explanation:
t = total tickets sold
If each ticket cost $3 and the class raised $504, just divide the total amount by the cost.
I hope this helps you! Please tell me if I am wrong!
x²+x=0
x³-25x=0
x²=4x
4x²-4x=1
Answer:
x²+ x = 0
x ( x +1 ) = 0
x = -1
x³-25x=0
x ( x² - 25 ) = 0
x² = 25
x = 5
x²=4x
x² - 4x = 0
x ( x- 4 ) = 0
x = 4
4x²-4x=1
4x²-4x - 1 = 0
4 x² - 2x - 2x - 1 = 0
2x ( 2x - 1 ) - 1 ( 2x- 1 ) = 0
2x- 1 ) ² = 0
2x = 1

How do we solve 56x + 79 if x = 23? (30 points!) GIVE A GOOD EXPLANATION, NOT JUST AN ANSWER, WHO EVER DOES IT FIRST GETS BRAINLIEST.
Hello friend!
The answer is: 1367
First, since x = 23, we rewrite the problem.
56(23) + 79 = ?
Now we need to figure out 56 time 23
56 times 23 = 1288
Now we have 1288 + 79.
1288 + 79 = 1367
Answer:
1,367
Explanation:
Step 1 - Input the value of x in the given expression
56x + 79
56(23) + 9
Step 2 - Multiply fifty six by twenty three
56(23) + 79
56 × 23 + 79
1,288 + 79
Step 3 - Add
1,288 + 79
1,297
Therefore, the answer to the given expression is 1,367.

Answer:
14 cm
Step-by-step explanation:
from the right triangle we know that:
- A leg is 8 cm
- B leg is 11 cm
- angle between A and B leg is 90'
If we have one angle which is 90' we can use the following formula:
[tex]c = \sqrt{a^{2} + {b^{2} }[/tex]
[tex]c = \sqrt{8^{2} + {11^{2} }[/tex]
[tex]c = 13.60147[/tex]
A baker has three banana muffin recipes. Recipe AAA uses 333 bananas to make 121212 muffins. Recipe BBB uses 555 bananas to make 242424 muffins. Recipe CCC uses 111111 bananas to make 484848 muffins. Order the recipes by number of bananas per muffin from least to greatest.
Answer:
The order from least to greatest is B, A, C
Step-by-step explanation:
Given
Recipe A = 3 bananas to 12 Muffins
Recipe B = 5 bananas to 24 Muffins
Recipe C = 11 bananas to 48 Muffins
Required
Order the recipe from least to greatest
To solve this, we have to divide the number of bananas by number of muffins; this will give the unit banana per muffin
Recipe A: 3 bananas to 12 Muffins
[tex]A = \frac{3}{12}[/tex]
[tex]A = 0.25[/tex]
Recipe B: 5 bananas to 24 Muffins
[tex]B = \frac{5}{24}[/tex]
[tex]B = 0.2083[/tex]
Recipe C: 11 bananas to 48 Muffins
[tex]C = \frac{11}{48}[/tex]
[tex]C = 0.229167[/tex]
By comparison;
Recipe B (0.2083) is the smallest; followed by Recipe C (0.229167) then Recipe A (0.25)
Hence; the order from least to greatest is B, A, C

how to do this question plz answer me step by step plzz plz
Answer:
2 Pi
Step-by-step explanation:
Notice that the shape is made of:
● 1 square with a side of 1 meter length
● 4 half-circles wich means 2 cicles with a diameter lf 1 meter.
■■■■■■■■■■■■■■■■■■■■■■■■■■
The square is inside so it isn't necessary to calculate the perimeter.
The perimeter of a circle is:
P' = d × Pi
We have 4 half-squares wich means two circles
So the total perimeter is:
● P = 2×P'
● P = 2 × d × Pi
● P = 2 × 1 × Pi
● P = 2Pi

4. Solve for x
please help!!
Answer:
x = -5
Step-by-step explanation:
Isolate the variable x:
-3x = 15
Since x is being multiplied by -3, we must find a way to cancel it out. To cancel -3 being multipled, divide by -3 instead. Remember, whatever we do to one side of the equation, we must do to the other!
-3x ÷ -3 = 15 ÷ -3
1x = -5
x = -5
Answer:
[tex] - 3x = 15 \\ \frac{ - 3x}{ - 3} = \frac{15}{ - 3} \\ x = - 5[/tex]
