Answer:
11i= √-1
Step-by-step explanation:
So first take 1 to the other side so we can leave the numbers with I on one section. So when we take 1 to the other side it becomes negative so 0-1 = -1. Since the 8 is squared to get rid of it were going to put a square root on the whole equation. √8i² + 9i = √-1 and we have to put the square root on the other side of the equation to make it equal. So on the other side we now have 8i + 3i *because the square root of 9 is 3* and then the -1 stays like that so its 11i= √-1 because we combine the 8i and 3i. Happy I could help!!!

A factory makes rods by cutting plastic pipes that are 4 feet long into 7 equal-sized rods. How long is each rod? (enter your answer as a fraction or a mixed number)
What is the total length of 15 rods? (enter your answer as a fraction or a mixed number)
Answers
Answer:
4/7
Step-by-step-- It is given that we have cut the 4 ft long.
We have to make it into 7 times it's original piece.
To determine this Is the length of the new rods.
Let the length of each new rod be x.
We need 7 rods-
7x = 4 ft
1 = 4/7x
x = 4x/7x
So, x gets cancelled. Now, we get the answer as . 4/7

Find the measure of arc CD in p
Answers
9514 1404 393
Answer:
57°
Step-by-step explanation:
TD is a diameter, so arc TCD is 180°. Then arc CD is ...
CD = arc TCD -arc TC
CD = 180° -123°
arc CD = 57°
Find the measure of arc CD in P.
___________________Solution :-Given Information :-Arc TC = 123°Arc TCD = 180° ( Reason :- Arc TCD is the diameter of circle )Arc BT = 90° To Find :-Measure of Arc CD Calculation :-Because Arc TC and Arc CD comprise the Arc TCD,
⇒ Arc TC + Arc CD = Arc TCD
Substituting the values given, We get,
⇒ 123° + Arc CD = 180° ( Reason :- Arc TCD is the diameter of circle )
Now, Transposing 123° to Right Hand Side, We get,
⇒ Arc CD = 180° - 123°
⇒ Arc CD = 57°
∴ Arc CD = 57°
____________________Final Answer :-Arc CD measures 57°

Answer:
Alright, with this, its essentially asking for you to plug in X into each equation for the answer.
With the first box, it asks for y = 5 - x, given the x = -2.
y = 5-x
y=5-(-2)
y=5+2
y=7
With the second box down, it wants things a bit differently, it gives you the y value, and wants for you to find the x. Given this, this question can be done backwards for the x value.
y = 5-x
6 = 5-x
x+6= 5
x=-1
With the third one, its the same thing as with the first box.
y = 5-x
y = 5-0
y = 5
Same thing with the fourth one.
y = 5-1
y = 4

Can someone plz help me on this plz I beg u
Answers
Answer:
8
Step-by-step explanation:
So, lets go over a few things:
First off, all triangles have a total angle of 180 degrees.
Secondly, we know that the first two angles are 57 and 51.
Thirdly, we know that the missing angle is 9x
To solve this, we must add together the known angles, subtract them fro 180, and divide that by 9. This will give us the missing x value.
So, add together the two angles we know:
57+51
=
108
So we know 108 degrees of our triangle. We must find whats left of the 180.
To do this, subtract 108 from 180:
180-108
=
72
So our remaining angle is 72 degrres.
But recall that x isnt the misisng angle, 9x is.
So, to get x on its own, we must divide both the missing angle and 9x by 9:
72=9x
--- ---
9 9
=
8=1x
So now we know that x equals 8.
I hope this helps! :)
Answer:
X = 8
Step-by-step explanation:
Okay so we know that there are a total of 180 degrees in every triangle. We need to create the equation to define the triangle's angles. 51 + 57 + 9x = 180. Then, we will solve for x.
180 = 51 + 57 + 9x we are going to simplify the equation by solving what we can
180 = 108 + 9x * Now we will isolate x
180 - 108 = 9x * Solve the left side of the equation
72 = 9x * Divide both sides by 9
8 = x

to the movies? (7.10A)
Item

Cost (S)
6.00
6.00
popcom
candy
3.50
Answers
Answer:
6x + 25 ≤ 135
Step-by-step explanation:
Maximum amount to spend = $135
Boxes of popcorn = 2
Boxes of candy = 3
Cost per box of popcorn = $6
For 3 boxes = $6 * 3 = $18
Cost per box of candy = $3.50
For 2 boxes = $2 * 3.50 = $7
Item cost = Cost of candy and popcorn = $18 + $7 = $25
Ticket price = $6
Inequality to find number of friends ;
Let number of friends = x
Ticket cost = 6x
Hence ;
Ticket cost + item cost ≤ 135
6x + 25 ≤ 135
