how do we know 35° is complementary to 55°
Answers
Answer: Complementary angles are two angles whose measures add up to 90° . Two angles need not be adjacent to be complementary. The angles in the next figure are also complementary, since 35°+55°=90° . See also supplementary angles .
Answer:
because complementary is equal to 90 degrees so add 35 and 55 degrees up together it equals 90 degrees

Jessica, Chau, and Kareem sent a total of 84 text messages during the weekend. Kareem sent 4 times as many messages as Chau. Jessica sent 6 fewer messages than Chau. How many messages did they each send?
Answers
Answer:
Number of messages sent by Chau = 15
Number of messages sent by Kareem = 4 * 15 = 60
Number of messages sent by Jessica = 15 - 6 = 9
Step-by-step explanation:
Let number of messages sent by Chau = c
Number of messages sent by Kareem = 4 times as Chau
= 4 * c = 4c
Number of messages sent by Jessica = 6 fewer messages than Chau
= c - 6
Total messages = 84
c + 4c + c - 6 = 84 {Combine like terms}
6c - 6 = 84 {Add 6 to both sides}
6c = 84 + 6
6c = 90 {Divide both sides by 6}
c = 90/6
c = 15
Number of messages sent by Chau = 15
Number of messages sent by Kareem = 4 * 15 = 60
Number of messages sent by Jessica = 15 - 6 = 9
Kareem = 4*15 = 60
Jessica = 15-6 = 9

Polygon JKLM is drawn with vertices J(−4, −3), K(−4, −6), L(−1, −6), M(−1, −3). Determine the image coordinates of L′ if the pre-image is reflected across y = −3.
L′(−3, 6)
L′(−1, 6)
L′(−1, 0)
L′(1, 0)
Answers
To reflect the pre-image across y = -3, we need to flip the entire polygon over the line y = -3. This means that the x-coordinates of each point will remain the same, but the y-coordinates will be reflected across the line.The y-coordinate of point L is -6, which is 3 units below the line y = -3. When reflected, this point will be 3 units above the line y = -3. Therefore, the image coordinates of L' will be (−1, 0), since the x-coordinate of L is -1 and the y-coordinate of L' is 3 units above y = -3, which is 0.So, the image coordinates of L' are (−1, 0).

Answers
Answer:
1872 ft.²
Step-by-step explanation:
First lets figure out all of the easy shapes:
The bottom one: 8 * 7 = 56
The one on the left: 5 * 8 = 40
The one of top: 8 * 3 = 24
The slanted rectangle: 5 * 8 = 40
The small rectangle below that : 2 * 8 = 16
Now we just have the polygon facing toward us. It can be broken up into 2 parts:
The lower half: 2 * 7 = 14
Imagine a line going from the top of the line marked "2" straight across to the other side. That is the bottom half. Now we are left with a trapezoid. The formula for the area of a trapezoid is as follows:
A = ((a + b) / 2) * h
What this means is that we had the top and bottom of the figure, divide that by 2, and multiply it by the height. That can be shown here:
(3 + 7) / 2 = 5 * 3 = 15
15 is the area of the trapezoid. Now we can combine that with 14 to get the total area of the polygon:
14 + 15 = 29
Then do the same again for the other identical figure
14 + 15 = 29
Now we have all the areas of our shapes. Let's add them up:
56 + 40 + 24 + 40 + 16 + 29 + 29 = 234
234 is the total surface area of the box. Since there are 8 boxes, multiply this by 8 to get your final answer:
234 * 8 = 1872 ft.²
Don't forget to include units!
The solution is : 1872 ft.² of the new material is needed to build all 8 containers.

x-2y=3, x^2-2y=3, x^2-2xy+4y^2=11, find the value of x^2y-2xy^2
Answers
This is a system of three equations with two unknowns, x and y. To solve it, we can use the method of elimination. First, we can eliminate y by subtracting the first equation from the second equation:
x^2-2y=3 - (x-2y=3) => x^2-x=0
Then we can factor the resulting equation and find the values of x:
x^2-x=0 => x(x-1)=0 => x=0 or x=1
Next, we can substitute these values of x into any of the original equations and find the corresponding values of y. For example, using the first equation:
x-2y=3 => 0-2y=3 => y=-3/2 when x=0 x-2y=3 => 1-2y=3 => y=-1 when x=1
Finally, we can substitute these values of x and y into the expression x2y-2xy2 and evaluate it:
x2y-2xy2 => 02(-3/2)-2(0)(-3/2)2 => 0 when x=0 and y=-3/2 x2y-2xy2 => 12(-1)-2(1)(-1)2 => -3 when x=1 and y=-1
Therefore, the value of x2y-2xy2 can be either 0 or -3 depending on the values of x and y.

Answer:

Step-by-step explanation:
The integer in the replacement set that will make the equation true is (d) 18
How to determine the solution to the expression?From the question, we have the following parameters that can be used in our computation:
"23 of a number is 12."
Rewrite properly
So, we have
"2/3 of a number is 12."
Express as an equation
This gives
2/3p = 12
Where the variable is p
Multiply 3/2 to both sides of the expression
So, we have the following representation
3/2 * 2/3p = 12 * 3/2
Evaluate the products on both sides of the equation
p = 18
Hence, the solution is p = 18
