Try these solutions:
<u>Task 1.</u>
a) the required angle is arctan(CG/AC);
b) according to the condition CG=AE=11.4 (cm.);
c) BC=EH=9.6 (cm.), then
d) the required angle is:
Answer: 29°
<u>Task 2.</u>
a) the required angle is EFV (see the attached picture): arctan(EV/FE);
b) to calculate FE: FE=0.5AB=7.25 (cm.);
c) to calculate EV:
d) to calculate the required angle:
m(∠EFV)=arctan(13.80996/7.25)=arctan(1.9048)≈62.302°=62°.
Answer: 62°
Answer:
A.) 34 = 10 + 4x
Step-by-step explanation:
This equation would mean the customer rented one bike ($10) plus the hours they had it ($4 per hour) for x hours.
That means the equation would look like this 10 + 4x = 34
The dimensions are multiplied by 2 so the volume is multiplied by 2^3 ( - 8)
The jumbo bos will contain 250 * 8 = 2,000 paperclips.
The answer is: "No."

Explanation:
_____________________________
Given: y = 5x - 1 ;
is: (1, -2) a solution?
______________________________
When "x" = 1, does "y" = -2 ?
______________________________
5*(-2) - 1 = -10 - 1 = -11 . No.
_________________________________
So, the answer is: No.

Answer:
y=4.875
x=.75
Step-by-step explanation:
6x-y=16
3x+2y=12
2(6x-y=16)=
12x-2y=32
3x+ 2y=-12
(get rid of Y and add down)
15x=20
x=15/20= 3/4= .75
if x= 3/4 then
3(.75) +2y= 12
2.25+ 2y=12
2y=9.75
y=4.875
(i hope i did this right if not im sorry!!)
