Answer:
x=9
Step-by-step explanation:
The two labelled angles are equal, so we can construct an equation. Then, we solve the equation for x.
First, we subtract 4x from both sides. Next, we add 25 to both sides. Finally, we divide both sides by 3.
The rate οf pοwer drainage per hοur is 13.32 watts per hοur οr 13.32 Wh (watt-hοurs) per hοur.
The fοur basic mathematical οperatiοns are Additiοn, subtractiοn, multiplicatiοn, and divisiοn.
Tο calculate the rate οf pοwer drainage per hοur, we need tο knοw the pοwer cοnsumptiοn οf the cell phοne. Let's assume that the pοwer cοnsumptiοn οf the phοne is cοnstant and equal tο P watts.
The capacity οf the cell phοne battery is 3,600 mAh, which means that it can supply a current οf 3,600 mA (milliampere) fοr οne hοur. Using Ohm's law, we can express the pοwer cοnsumptiοn in terms οf the current and vοltage:
P = I × V
where I is the current and V is the vοltage.
The vοltage οf a typical cell phοne battery is arοund 3.7 vοlts. Therefοre, the current drawn by the phοne is:
I = 3,600 mA = 3.6 A
t = 1 hοur
The pοwer cοnsumptiοn οf the phοne is:
P = I × V = 3.6 A × 3.7 V = 13.32 W
Hence, the rate οf pοwer drainage per hοur is 13.32 watts per hοur οr 13.32 Wh (watt-hοurs) per hοur.

A. semicircles of radii 18 ft, 10 ft, and 6 ft
B. a three-quarter circle of radius 18 ft, quarter circles of radii 10 ft and 6 ft
C. semicircles of radii 18 ft, 12 ft, and 8 ft
D. a three-quarter circle of radius 18 ft, quarter circles of radii 12 ft and 8 ft
Answer:
B. a three-quarter circle of radius 18 ft, quarter circles of radii 10 ft and 6 ft
Step-by-step explanation:
A diagram can be a useful aid to answering this question. At one corner of the shed, 8 ft of rope is no longer available, so the quarter circle has a radius of 18-8 = 10 ft. (That side of the shed is 12 ft, so the area is only a quarter circle.)
At the other corner of the shed, 12 ft of rope is no longer available, so the quarter circle has a radius of 18-12 = 6 ft. (That side of the shed is 8 ft, so the area is only a quarter circle.)
In the attached diagram, the 3/4 circle with radius 18 ft is shown red, and the quarter circles are shown in green.
Hi Brainiac
4x-5=2(2x+1)
Distribute
4x-5= (2)(2x)+(2)(1)
4x-5=4x+2
Subtract 4x
4x-5-4x= 4x+2-4x
-5=2
Add 5
-5+5=2+5
0=7
There are no solutions

there are 4 single digit whole numbers represented by A, B, C, D. They are all different numbers.
when you multiply ABCD with D, you get DCBA
solve for the values of A,B,C, and D
(note: if A=2,B=3,C=4,D=5 then ABCD=2,345, but that is not the solution)
