Answer:
(x, y) = (2 2/9, -1 4/9)
Step-by-step explanation:
Equate the values of y and solve for x.
1/4x -2 = -2x +3
(2 1/4)x = 5 . . . . . . . . add 2+2x to both sides
x = 20/9 = 2 2/9 . . . multiply by 4/9
y = -2(2 2/9) +3 = -4 4/9 +3 . . . . substitute for x in the second equation
y = -1 4/9
The solution is x = 2 2/9, y = -1 4/9.
I'm may not be that good at math, but I'm going to try my best to help you, because I know how it feels to be in this situation!
The first one :
You might be right on D. But I'm thinking B also. The question asks "Which could be a cross section of a rectangular pyramid that has been intersected by a plane perpendicular". But a triangle is basically a flat pyramid.
(I'm typing really fast to help!!!!)
Second one: Its B!! Look at it really closely! You'll get it!!!
(Going really fast now!!!!)
Third one: Between B or D!!! But I think you're right on your choice!!!!
(FASTER FASTER!!!)
FINALLY: Copy and paste your answers into google. People have asked the same question!
I hope I helped. I don't want to make you fail, as I am in the SAME similar situation as you! I really REALLY REALLY HOPE YOU PASS!!!
First you convert centimeters to meters which will be 35 centimeters-> 0.35 meters
Once you have that, you multiply String A's length (0.35 m) by 5 to find String B's length which will be 1.75 meters.
Now that you have the two lengths you multiply each by 17.
17 x 1.75 = 29.75 and 17 x 0.35 = 5.95
Now you just add 29.75 and 5.95 and you get your answer which is
35.7 meters
Answer:
8
Step-by-step explanation:
Hello!
I believe the answer is 58°.
Explanation: In order to find this answer, we must first add up the two numbers; 87+35. After adding, your solution should be 122. In order to be a triangle, all of the degrees must all add up to 180°. Next we must subtract 122 from 180. After subtracting, the answer is 58. Therefor your answer is 58°.
