Answer:
90°
Step-by-step explanation:
Any corner angle in a rectangle is 90°. Rotating the figure does not change that. Angle O' = 90°.
_____
Additional comment
No rigid transformation (translation, rotation, reflection) changes any angles. Nor does uniform dilation (the kind we usually study). Hence any rectangle that is translated, rotated, reflected, or dilated will still have all angles measuring 90°.
If a series RC circuit is operating at 100 VAC and has an impedance of 52.5 ohms, what is the circuit current
Answer:
1.9 Amps
Step-by-step explanation:
In an RC circuit, the relationship between the current I in amps, the impedance Z in ohms and the voltage V in volts may be stated as
V = IZ
As such, given that z = 52.5 ohms and V = 100 Volts, the current in the circuit I may be computed as
100 = I * 52.5
Divide both sides by 52.5
I = 100/52.5
= 1.9 Amps

Gym a charges $25 per month plus a $60 initiation fee. Gym b charges $30 per month and no initiation fee. Find the number of months it will take for the total cost for both gyms to be equal
Answer:
12 months
Step-by-step explanation:
Given data
Gym A
charges $25 per month plus a $60 initiation fee
let the number of months be x
and the total charges be y
y= 60+25x---------------1
Gym B
charges $30 per month and no initiation fee
let the number of months be x
and the total charges be y
y=30x---------------2
Equate 1 and 2 above to find x
60+25x= 30x
collect like terms
60= 30x-25x
60= 5x
divide both sides by 5
x= 60/5
x= 12
Hence it will take 12 months

A cylindrical container contains some sand. If the diameter of the container is 10 inches and its height is 3 inches, about how much sand fits inside the container?
Answer:
251.33in²
Step-by-step explanation:
A cylindrical container contains some sand. If the diameter of the container is 10 inches and its height is 3 inches, about how much sand fits inside the container?
We solve the above question using the formula for Total surface area of a cylinder.
TSA = 2πr (h + r) Square units.
Where
h = Height of the cylinder
r = Radius of the cylinder
Diameter of the container is 10 inches
Hence, radius = Diameter/2 = 10/2 = 5 inches
Height is 3 inches.
Hence, Total surface area =
2 × π × 5 (5 + 3)
= 10π × (8)
= 251.32741229 in²
Approximately = 251.33 in²
Therefore, the amount of sand that can fit into the cylinder = 251.33 in²

i need help ASAP
(4,−4), (k,−1); m=3/4 i need to know what k is
Answer:
8
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
3/4=(-1-(-4))/(k-4)
3/4=(-1+4)/(k-4)
3/4=3/(k-4)
cross product
4*3=3(k-4)
12=3(k-4)
12/3=k-4
4=k-4
k=4+4
k=8

Complete Question
William has $7.50 to spend at the pretzel shop. A large pretzel costs $1.25 and a soft drink costs $0.90. He buys one drink and p pretzels. Which inequality can be used to find the number of pretzels William can buy?
a) 1.25p−0.9≤7.5
b) 1.25p+0.9≤7.5
c) 1.25p+0.9≥7.5
d) 1.25+0.9p≤7.5
Answer:
b) 1.25p+0.9≤7.5
Step-by-step explanation:
William has $7.50 to spend at the pretzel shop.
This means Williams can spend at least $7.50
A pretzel costs $1.25 and a soft drink costs $0.90. He buys one drink and ?pretzel
Therefore, the inequality can be used to find the number of pretzels William can buy is written as
1.25p+0.9≤7.5

x-4=-x+2
Answer:x=3
Step-by-step explanation:
Answer: x=3
Step-by-step explanation:
Given
x-4=-x+2
Add x on both sides
x-4+x=-x+2+x
2x-4=2
Add 4 on both sides
2x-4+4=2+4
2x=6
Divide 2 on both sides
2x/2=6/2
x=3
